Federal Revenue in America 2025

The federal revenue landscape in the United States during 2025 has demonstrated remarkable dynamics, reflecting both economic resilience and significant policy shifts. The federal government’s ability to generate revenue remains fundamental to funding critical national programs, infrastructure development, and public services that millions of Americans depend on daily. Throughout fiscal year 2025, which runs from October 1, 2024, to September 30, 2025, the nation witnessed unprecedented changes in revenue composition, particularly driven by new trade policies and sustained economic growth that bolstered traditional tax collections.

Understanding federal revenue in 2025 provides essential insights into the nation’s fiscal health and economic trajectory. According to the Congressional Budget Office, total federal revenue reached approximately $5.2 trillion in fiscal year 2025, representing a 6 percent increase from the previous year. This growth reflects multiple contributing factors including rising wages that expanded payroll tax collections, increased individual income tax receipts from a robust labor market, and historic surges in customs duties resulting from expanded tariff policies. The revenue composition reveals how the government finances essential services ranging from Social Security and Medicare to national defense and infrastructure investments, making it imperative for citizens, policymakers, and analysts to comprehend these financial flows that underpin America’s economic foundation.

The remarkable transformation in federal revenue composition in 2025 showcases how policy decisions directly impact government finances. The explosive growth in customs duties from tariff implementations represents one of the most dramatic shifts in revenue sourcing witnessed in decades. Monthly collections quadrupled from baseline levels, fundamentally altering the revenue mix that traditionally relied heavily on income and payroll taxes. This shift demonstrates the government’s evolving approach to revenue generation while highlighting ongoing debates about trade policy effectiveness and economic impacts on American businesses and consumers.

Equally significant is the milestone crossing of $1 trillion in net interest payments on the public debt, representing a watershed moment in federal finances. This figure underscores mounting fiscal pressures as accumulated debt requires increasingly substantial servicing costs that compete with funding for discretionary programs. The combination of elevated debt levels and rising interest rates created this historic threshold, signaling long-term challenges for fiscal sustainability that policymakers must address through balanced approaches to revenue enhancement and spending prioritization.

Individual Income Tax Revenue in the US 2025

Income Tax Category Amount (Billions) Percentage of Total Revenue Year-over-Year Change
Total Individual Income Tax $2,600 billion 50% +$185 billion
Withheld Taxes $2,100 billion 40% +6%
Non-Withheld Payments $350 billion 7% -11% (adjusted for timing)
Refunds Issued ($450 billion) N/A -5%
Average Tax Rate (All Filers) 14.5% N/A Stable
Top 1% Average Rate 26.1% N/A Higher than other groups

Data Source: Congressional Budget Office, Internal Revenue Service Statistics of Income, Penn Wharton Budget Model Federal Budget Tracker

Individual income taxes maintained their position as the cornerstone of federal revenue in 2025, generating approximately $2.6 trillion and accounting for half of all government receipts. The strength in income tax collections reflected robust labor market conditions throughout the year, with employment levels remaining elevated and wage growth continuing across most sectors. Withheld taxes, which employers deduct from employee paychecks, showed particular resilience with a 6 percent increase totaling approximately $82 billion more than the previous year. This growth directly correlated with rising compensation levels as businesses competed for talent in a tight labor market, automatically expanding the tax base without rate increases.

The progressive nature of the federal income tax system continued driving revenue patterns, with higher-income earners contributing disproportionately larger shares. Data from tax year 2022 (the most recent available) revealed that taxpayers in the top 1 percent of the income distribution, those with adjusted gross income exceeding $663,164, paid an average tax rate of 26.1 percent, which was seven times higher than the 3.7 percent rate paid by taxpayers in the bottom half of the income distribution. This progressivity ensures that revenue collections respond dynamically to economic conditions affecting different income groups, with capital gains realizations, bonuses, and business income from high earners creating revenue volatility that budget forecasters must carefully monitor throughout each fiscal year.

Social Insurance and Payroll Tax Revenue in the US 2025

Payroll Tax Type Amount (Billions) Tax Rate Wage Base Limit Growth Rate
Total Payroll Taxes $1,800 billion N/A N/A +6%
Social Security Tax $1,200 billion 12.4% (split employer/employee) $176,100 (2025) +6%
Medicare Tax $450 billion 2.9% (split employer/employee) No limit +5%
Additional Medicare Tax $30 billion 0.9% (employee only) $200,000+ income +7%
Unemployment Insurance $50 billion Varies by state State-specific Stable
Federal Employee Retirement $70 billion Various rates N/A +4%

Data Source: Congressional Budget Office, Social Security Administration, Centers for Medicare & Medicaid Services

Payroll taxes, also known as social insurance taxes, represented the second-largest revenue source for the federal government in 2025, collecting approximately $1.8 trillion or roughly 35 percent of total receipts. These dedicated taxes fund specific social insurance programs including Social Security retirement and disability benefits, Medicare hospital insurance, and unemployment compensation. The 6 percent growth in payroll tax collections mirrored the expansion in individual income tax withholdings, both driven by the same underlying factor of increased wage and salary income across the American workforce. With more people employed and earning higher wages, the automatic nature of payroll tax withholding ensured steady revenue flows throughout the year.

The structure of Social Security taxation creates interesting dynamics in revenue generation. For 2025, the taxable wage base stood at $176,100, meaning any wages earned above this threshold were not subject to the 12.4 percent Social Security tax. This cap affects revenue progressivity, as high-income earners pay Social Security tax on only a portion of their total compensation while paying Medicare taxes on all earnings. The Additional Medicare Tax of 0.9 percent on earnings exceeding $200,000 partially addresses this discrepancy, generating approximately $30 billion annually from high-income taxpayers. The reliability of payroll tax revenues makes them crucial for long-term program planning, though demographic shifts with aging baby boomers retiring continue creating sustainability challenges that require ongoing policy attention to maintain promised benefits for future generations.

Corporate Income Tax Revenue in the US 2025

Corporate Tax Metric Amount/Rate Details Change from 2024
Total Corporate Tax Revenue $470 billion 9% of total revenue -$32 billion
Statutory Tax Rate 21% Permanent since 2017 TCJA No change
Effective Tax Rate ~15-18% After deductions and credits Stable
Number of C Corporations 2.4 million Subject to corporate tax Slight increase
April Collections $110 billion Quarterly payment month +4%
Corporate Share of GDP 1.7% Historical comparison Above 2024

Data Source: Congressional Budget Office, Internal Revenue Service, U.S. Treasury Department, Tax Foundation

Corporate income tax collections in fiscal year 2025 generated approximately $470 billion, representing about 9 percent of total federal revenue. While this marked a slight decline of roughly $32 billion compared to 2024, corporate tax receipts remained broadly in line with Congressional Budget Office projections made at the beginning of the year. The decline primarily stemmed from timing issues related to disaster-related tax deadline postponements from 2023 that artificially boosted 2024 collections, creating a difficult year-over-year comparison. When adjusted for these timing shifts, corporate tax revenues demonstrated resilience despite global economic uncertainties and fluctuating business profitability across different sectors.

The 21 percent statutory corporate tax rate, made permanent by the Tax Cuts and Jobs Act of 2017, continues shaping business decisions and revenue patterns. However, actual effective tax rates paid by corporations typically range between 15 to 18 percent after accounting for various deductions, credits, and international tax provisions. Corporate tax revenue as a percentage of GDP reached 1.7 percent in 2025, exceeding pre-TCJA projections and demonstrating that lower rates combined with broader bases and improved enforcement can generate substantial revenues. The evolution of corporate taxation reflects ongoing balancing acts between maintaining international competitiveness, ensuring adequate revenue contributions from profitable businesses, and addressing concerns about corporations using complex structures to minimize tax obligations while benefiting from American infrastructure and legal systems.

Customs Duties and Tariff Revenue in the US 2025

Customs Duty Metric Amount (Billions) Key Details Percentage Change
Total Customs Duties FY 2025 $195 billion Record annual collection +250% from 2024
First Half Collections $44 billion October 2024 – March 2025 Baseline period
Second Half Collections $151 billion April – September 2025 +300% surge
January 2025 Monthly $7 billion Pre-escalation baseline Normal rate
September 2025 Monthly $30 billion Post-tariff implementation 328% increase
Average Effective Tariff Rate 9.75% July 2025 Up from 2.2% in January
China-specific Tariff Rate 40% Highest among trading partners Substantial increase

Data Source: Committee for a Responsible Federal Budget, U.S. Customs and Border Protection, Penn Wharton Budget Model, Congressional Budget Office

The most dramatic revenue story of fiscal year 2025 centered on customs duties, which experienced an unprecedented surge to $195 billion, representing more than a 250 percent increase from the previous year’s collections. This explosive growth stemmed from the Trump Administration’s implementation of sweeping new tariff policies throughout the year, fundamentally transforming customs duties from a relatively minor revenue source into the fourth-largest contributor to federal receipts. The monthly trajectory illustrated the policy’s escalating impact, with collections jumping from $7 billion in January to $30 billion by September, creating a revenue arc that dramatically reshaped federal budget projections and sparked intense debates about trade policy effectiveness.

The second half of fiscal year 2025 proved particularly consequential, with $151 billion collected between April and September, nearly 300 percent higher than the comparable period in 2024. This timing reflected both the phased implementation of tariff increases and initial delays as businesses adjusted purchasing patterns. The average effective tariff rate climbed to 9.75 percent by July, a fourfold increase from the 2.2 percent rate at the year’s beginning, with certain products and countries facing substantially higher rates. Steel and aluminum products bore the highest burden at 41.2 percent, while automotive vehicles faced 22.3 percent rates, and goods from China encountered 40 percent average duties, showcasing how targeted tariffs concentrated on specific sectors and trade relationships. This revenue windfall, however, came with significant uncertainty, as court challenges to tariff authority threatened to require refunds of potentially $90 billion if adverse rulings were ultimately upheld by the Supreme Court.

Other Federal Revenue Sources in the US 2025

Revenue Source Amount (Billions) Percentage of Total Primary Uses/Notes
Excise Taxes $95 billion 1.8% Gasoline, tobacco, alcohol, airline
Estate and Gift Taxes $27 billion 0.5% Estates over $13.99 million
Customs Fees (Non-tariff) $15 billion 0.3% User fees, merchandise processing
Federal Reserve Earnings $55 billion 1.1% Interest on securities held
Fees and Fines $40 billion 0.8% Regulatory fees, park admissions
Miscellaneous Receipts $28 billion 0.5% Various government services
Total Other Sources $260 billion 5.0% Combined smaller sources

Data Source: U.S. Treasury Department Monthly Treasury Statements, Congressional Budget Office, Federal Reserve System

Beyond the major revenue categories, federal revenue in 2025 included approximately $260 billion from various other sources, collectively representing 5 percent of total receipts. Excise taxes remained the largest component of this miscellaneous category, generating $95 billion from taxes on specific goods and services including gasoline, aviation fuel, tobacco products, alcoholic beverages, and health-related items. These taxes serve dual purposes of raising revenue and influencing behavior, with tobacco and alcohol taxes explicitly designed to discourage consumption while transportation-related excise taxes help fund highway and airport infrastructure. The 55 percent increase in excise tax collections during 2025 reflected both higher consumption levels and rate adjustments across multiple categories.

Estate and gift taxes contributed $27 billion to federal coffers, though this represented a shortfall of approximately $5 billion compared to projections, potentially reflecting estate planning strategies or valuation timing issues. The 2025 exemption threshold of $13.99 million per individual meant that only the wealthiest 0.13 percent of decedents faced estate taxation, making this one of the most progressive elements of the federal tax system. Federal Reserve earnings transferred to the Treasury provided $55 billion, though this figure remained substantially below historical peaks as elevated interest rates paid on reserves reduced the central bank’s net income. The diversity of these smaller revenue sources provides fiscal flexibility and reduces over-reliance on any single tax base, though their combined contribution remains modest compared to income and payroll taxes that dominate federal financing.

Federal Revenue and GDP Relationship in the US 2025

Economic Indicator Value Historical Context Fiscal Impact
Revenue as % of GDP 17.3% Above 17.0% historical average Strong relative to economy
Nominal GDP $30.1 trillion Growth continued Expanded tax base
Budget Deficit $1.8 trillion 6.0% of GDP Above sustainable levels
Debt Held by Public $30.1 trillion 100% of GDP Debt reached GDP parity
Primary Deficit $800 billion Deficit excluding interest Structural imbalance
Revenue Growth vs GDP Growth 6% vs 5% Revenue outpaced economy Progressive tax effects

Data Source: Congressional Budget Office, Bureau of Economic Analysis, U.S. Treasury Department

The relationship between federal revenue and GDP in 2025 provides crucial context for understanding fiscal sustainability. Federal receipts of $5.2 trillion represented 17.3 percent of gross domestic product, exceeding the 50-year historical average of 17.0 percent and signaling relatively robust revenue performance given economic conditions. This ratio matters because it normalizes revenue collections against the overall size of the economy, allowing meaningful comparisons across different time periods despite inflation and economic growth. The above-average revenue-to-GDP ratio reflected several factors including progressive tax structures that capture higher shares during prosperous periods, temporary revenue boosts from tariff policies, and continued economic expansion supporting employment and income growth.

Despite strong revenue performance, the federal government still recorded an $1.8 trillion deficit in fiscal year 2025, equal to 6.0 percent of GDP. This substantial gap between receipts and expenditures occurred because spending reached $7.0 trillion, or 23.3 percent of GDP, driven by mandatory program growth in Social Security and Medicare, elevated defense spending, and the historic crossing of $1 trillion in net interest costs. The persistent deficit pushed federal debt held by the public to $30.1 trillion, reaching 100 percent of GDP for the first time since the post-World War II era. Projections indicated further deterioration ahead, with debt potentially climbing to 118 percent of GDP by 2035 absent policy changes to narrow the gap between revenues and spending through some combination of tax increases, spending reductions, or economic growth acceleration.

Federal Revenue Allocation by Source in the US 2025

Revenue Source Amount (Trillions) Share of Total Primary Funding Purpose
Individual Income Taxes $2.60 50.0% General revenue – all programs
Payroll/Social Insurance $1.80 34.6% Social Security, Medicare, unemployment
Corporate Income Taxes $0.47 9.0% General revenue – all programs
Customs Duties $0.19 3.7% General revenue – all programs
Excise Taxes $0.10 1.9% Highway Trust Fund, other specific
Other Sources $0.04 0.8% Various government operations
Total Federal Revenue $5.20 100.0% All federal government operations

Data Source: Congressional Budget Office, U.S. Treasury Department, Committee for a Responsible Federal Budget

The allocation of federal revenue by source in 2025 revealed how different tax mechanisms contributed to overall government financing. Individual income taxes dominated with 50 percent of all receipts, providing flexible general revenue that Congress appropriates annually for discretionary programs including defense, education, transportation, and scientific research, while also funding portions of mandatory programs. This revenue source’s flexibility makes it the government’s primary tool for financing diverse national priorities, from military operations to federal law enforcement to space exploration, while its progressive structure ensures higher-income Americans contribute larger shares to common public goods and services.

Payroll taxes claiming 34.6 percent of revenue served dedicated purposes, primarily funding Social Security retirement and disability benefits and Medicare hospital insurance. Unlike income tax revenue that flows into the general fund for broad allocation, payroll tax receipts legally must support these specific social insurance programs, creating earmarked revenue streams that provide political protection and dedicated financing. The distinction between general revenue and earmarked taxes shapes fiscal debates, as Social Security and Medicare enjoy dedicated funding sources while other priorities compete for discretionary appropriations. Understanding this revenue structure proves essential for evaluating federal finances, as proposals to expand or contract different programs must account for their funding sources and the political feasibility of redirecting earmarked revenues or increasing general taxes to support new or expanded initiatives.

Federal Revenue Projections Through 2035 in the US

Fiscal Year Projected Revenue (Trillions) % of GDP Key Assumptions
2025 (Actual) $5.2 17.3% Baseline year
2026 $5.5 17.5% Continued economic growth
2027 $5.7 17.6% Tax provisions phase-in
2030 $6.5 18.0% Full implementation current law
2035 $8.0 18.3% Long-term projection
2026-2035 Total $67.5 18.1% average 10-year projection window

Data Source: Congressional Budget Office Budget and Economic Outlook (January 2025), American Action Forum Analysis

Looking beyond 2025, the Congressional Budget Office projects federal revenue will continue growing both in absolute terms and as a share of the economy, reaching $8.0 trillion or 18.3 percent of GDP by 2035. This increase reflects several factors including real economic growth expanding the tax base, progressive tax structures capturing larger shares as incomes rise, and scheduled phase-ins of tax provisions under current law. The projected revenue growth, however, proves insufficient to match anticipated spending increases, with outlays expected to reach $10.7 trillion or 24.4 percent of GDP by 2035, creating persistent deficits averaging nearly $2 trillion annually over the coming decade.

These 10-year revenue projections carry significant uncertainty, depending heavily on assumptions about economic growth rates, labor force participation, productivity gains, international trade patterns, and policy stability. Actual revenues could vary substantially from projections if economic conditions differ from forecasts, if major tax legislation passes altering rates or structures, or if tax administration and enforcement change compliance patterns. The baseline projections assume current law continues without major modifications, meaning scheduled expirations and phase-ins proceed as written, and new legislative changes are not anticipated. Policymakers face crucial decisions about whether to extend expiring tax provisions, implement new revenue measures to address deficits, or allow current law trajectories to play out, with each choice carrying different implications for economic growth, income distribution, and fiscal sustainability that will shape America’s financial landscape for decades.

Tax Revenue Distribution by Income Level in the US 2025

Income Percentile AGI Threshold Average Tax Rate Share of Total Taxes Share of Total Income
Top 1% $663,164+ 26.1% 42.3% 22.2%
Top 5% $261,591+ 22.4% 63.3% 38.6%
Top 10% $178,611+ 19.8% 74.1% 51.0%
Top 25% $100,399+ 15.4% 89.2% 70.1%
Top 50% $50,399+ 14.7% 97.7% 88.5%
Bottom 50% Under $50,399 3.7% 2.3% 11.5%

Data Source: Internal Revenue Service Statistics of Income, Tax Foundation Analysis (Tax Year 2022, most recent available)

The distribution of tax burdens across income levels in 2025 demonstrated the strongly progressive nature of the federal income tax system. Taxpayers in the top 1 percent of the income distribution, those with adjusted gross income exceeding $663,164, paid an average tax rate of 26.1 percent and contributed 42.3 percent of all individual income taxes collected despite earning 22.2 percent of total income. This concentration reflects both higher marginal tax rates applied to elevated income levels and the types of income high earners receive, including substantial amounts from capital gains, business income, and other sources beyond wages and salaries.

In contrast, taxpayers in the bottom 50 percent of the distribution, those earning under $50,399, faced an average tax rate of just 3.7 percent and collectively paid only 2.3 percent of total income taxes while earning 11.5 percent of all income. This pattern results from standard deductions and personal exemptions that shelter lower incomes from taxation, along with refundable tax credits like the Earned Income Tax Credit that can reduce tax liability below zero. The gap between the 26.1 percent average rate for top earners and the 3.7 percent rate for lower earners illustrates the tax code’s redistributive effects, though debates continue about whether progressivity should be enhanced, maintained, or reduced through future tax policy changes that balance revenue needs, economic growth objectives, and equity considerations.

Monthly Federal Revenue Patterns in the US 2025

Month Total Revenue (Billions) Key Features Year-over-Year Change
October 2024 $360 Fiscal year start +3%
January 2025 $420 Estimated payments +5%
April 2025 $850 Tax filing deadline peak +10%
June 2025 $526 Quarterly payments +13%
September 2025 $480 Fiscal year end +8%
April Surplus $256 Rare monthly surplus +$47 billion

Data Source: Congressional Budget Office Monthly Budget Reviews, U.S. Treasury Department Daily Treasury Statements

Federal revenue flows throughout 2025 followed predictable seasonal patterns while exhibiting notable growth compared to 2024. April traditionally represents the peak collection month due to the tax filing deadline, and 2025 proved no exception with $850 billion in receipts, $74 billion or 10 percent higher than the previous April. This surge generated a $256 billion monthly surplus, one of the rare occasions when monthly revenues exceeded spending, providing temporary relief to Treasury cash management and demonstrating the concentrated nature of income tax collections around filing deadlines when both final payments for the previous tax year and first quarter estimated payments for the current year come due simultaneously.

Other months showed more modest revenue levels, with collections typically ranging between $360 billion and $480 billion depending on the timing of quarterly estimated tax payments, payroll tax withholdings that flow steadily throughout the year, and corporate tax payments concentrated in specific months. The monthly variation in customs duties proved particularly dramatic during 2025, climbing from $7 billion in January to $30 billion by September as tariff policies took full effect. Understanding these monthly patterns helps Treasury officials manage government cash flows, borrow appropriately to cover shortfalls during low-revenue months, and invest surplus funds during high-collection periods. The predictability of these patterns, disrupted occasionally by disaster-related deadline extensions or legislative changes, provides some stability to fiscal planning despite the massive year-over-year growth in aggregate revenue that characterized this transformative fiscal year.

Tax Refunds and Processing in the US 2025

Refund Metric Amount/Figure Details Comparison
Total Refunds Issued $450 billion Full fiscal year -5% from 2024
Average Refund Amount $2,939 Per taxpayer +$70 from 2024
Returns Processed (Week 1) 11.7 million First week of filing season Strong start
Direct Deposit Refunds 28% Of first week returns Fastest method
Standard Processing Time 21 days For e-filed returns With direct deposit
Paper Check Processing 6-8 weeks Mail delivery Slower option
EITC/ACTC Refund Delay Mid-February Earliest issue date PATH Act requirement

Data Source: Internal Revenue Service Statistics, U.S. Treasury Department, Bipartisan Policy Center

The Internal Revenue Service processed and issued approximately $450 billion in tax refunds during fiscal year 2025, representing a 5 percent decrease from the previous year despite the average refund amount increasing to $2,939. This apparent contradiction reflected fewer taxpayers receiving refunds as wage withholding patterns adjusted and more precise tax payment calculations reduced overpayments that generate refunds. The 2025 filing season began on January 27, with the IRS processing 11.7 million returns in the first week alone, demonstrating robust taxpayer engagement and effective agency operations despite budget constraints and staffing challenges that had plagued previous years.

Processing speed improvements characterized the 2025 refund experience, with approximately 28 percent of first-week filers receiving direct deposit refunds, the fastest delivery method available. Taxpayers who filed electronically and selected direct deposit typically received their refunds within 21 days of filing, while those choosing paper checks faced 6 to 8 weeks of waiting. The IRS expanded its Direct File program to 25 states in 2025, up from 12 states in the initial pilot, providing free online filing for taxpayers with straightforward returns and contributing to higher e-filing rates that accelerated refund processing. However, refunds claiming the Earned Income Tax Credit or Additional Child Tax Credit faced delays under the PATH Act, which prohibits the IRS from issuing these refunds before mid-February to combat fraud, meaning many eligible taxpayers did not receive funds until early March despite filing in January.

State and Local Tax Deduction Changes in the US 2025

SALT Deduction Metric 2025 Amount Previous Amount Eligibility Details
New SALT Cap $40,000 $10,000 (pre-2025) Married filing jointly
Married Filing Separately $20,000 $5,000 (pre-2025) Half of joint cap

Annual Inflation Adjustment +1% per year N/A 2026-2029
Reversion Year 2030 N/A Returns to $10,000

Data Source: One Big Beautiful Bill Act (H.R. 1, Public Law 119-21), Joint Committee on Taxation, Bipartisan Policy Center

The most significant federal tax policy change affecting revenue in 2025 involved the dramatic expansion of the state and local tax deduction, commonly known as SALT. On July 4, President Trump signed the One Big Beautiful Bill Act into law, temporarily quadrupling the SALT deduction cap from $10,000 to $40,000 for tax year 2025. This change primarily benefited homeowners in high-tax states including New York, California, New Jersey, and Connecticut, where residents had been particularly impacted by the $10,000 cap imposed by the Tax Cuts and Jobs Act of 2017. The expanded deduction allows taxpayers who itemize to claim up to $40,000 in combined state and local income or sales taxes plus property taxes, substantially reducing federal tax liability for six-figure households facing significant state and local tax burdens.

The structure of the new SALT provision includes income-based limitations designed to concentrate benefits on upper-middle-class households rather than the very wealthy. Taxpayers with modified adjusted gross income exceeding $500,000 experience a 30 percent phaseout rate, reducing their available deduction by 30 cents for every dollar above the threshold. This phaseout continues until the deduction reaches the original $10,000 floor at $600,000 of income, ensuring that the highest earners receive no additional benefit from the expanded cap. The $40,000 cap and $500,000 threshold both increase by 1 percent annually through 2029, with the cap reaching approximately $41,600 and the threshold hitting $520,000 before reverting to the original $10,000 cap in 2030. This temporary expansion costs the federal government an estimated $140 billion over the 10-year budget window, representing a significant revenue sacrifice intended to deliver targeted tax relief to constituencies in high-cost areas.
