Yes, members of Congress pay taxes. Senators and representatives owe federal income tax, Social Security tax, Medicare tax, and state income tax under the same rules that apply to every other American worker. Their paychecks show the same automatic withholding you’d see on any W-2, and no provision in the tax code gives lawmakers a blanket exemption from any tax.
A rank-and-file senator or representative earns a base salary of $174,000, a figure that has not changed since 2009.1Office of the Clerk, U.S. House of Representatives. Salary Leadership positions pay more: the Speaker of the House earns $223,500, and the majority and minority leaders in both chambers each earn $193,400.2Congress.gov. Congressional Salaries and Allowances: In Brief All of that compensation counts as gross income under the Internal Revenue Code.
Federal Income Tax on Congressional Pay
For the 2026 tax year, the $174,000 base salary falls in the 24% marginal bracket for a single filer, which covers taxable income between $105,700 and $201,775.3Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 The Speaker’s salary crosses into the 32% bracket, which starts at $201,775. Married members filing jointly hit different thresholds, and deductions, credits, and outside income all shift the final bill, exactly as they would for any taxpayer.
Members who fail to file or pay on time face the same penalties as anyone else. The IRS charges a failure-to-file penalty of 5% of unpaid tax per month, capped at 25%, and a failure-to-pay penalty of 0.5% per month, also capped at 25%.4Office of the Law Revision Counsel. 26 USC 6651 – Failure to File Tax Return or to Pay Tax Willful tax evasion is a felony carrying fines up to $100,000 and up to five years in prison.5Office of the Law Revision Counsel. 26 USC 7201 – Attempt to Evade or Defeat Tax Those consequences apply whether the taxpayer is a first-year staffer or a sitting senator.
Social Security and Medicare
Congressional paychecks are subject to the same FICA withholding as any private-sector job. The Social Security tax rate is 6.2% on earnings up to the 2026 wage base of $184,500.6Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates Because the $174,000 base salary falls below that cap, every dollar of a rank-and-file member’s congressional pay is subject to Social Security tax. The Speaker’s salary exceeds the cap, so the portion above $184,500 is exempt from Social Security tax but not from Medicare.
Medicare tax is 1.45% on all earnings, with no upper limit. Members whose total wages exceed $200,000 also owe the Additional Medicare Tax of 0.9% on the excess.6Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates The Speaker and party leaders trigger that extra 0.9% automatically on part of their salary; rank-and-file members only hit it if outside income pushes them past the threshold.
This wasn’t always the case. Before 1984, members participated in a separate retirement system and didn’t contribute to Social Security at all. The Social Security Amendments of 1983 brought them into the system effective January 1, 1984, eliminating what had been one of the most visible tax differences between lawmakers and their constituents.7Social Security Administration.

State Income Tax
The one genuine wrinkle sits at the state level. Federal law fixes each member’s state tax residence as the state they represent, regardless of how much time they spend in Washington.8Office of the Law Revision Counsel. 4 USC 113 – Residence of Members of Congress for State Income Tax Laws The District of Columbia cannot treat a member as a D.C. resident or tax their congressional salary as D.C.-source income, even if the member owns a home there and sleeps in it most nights of the year. The D.C. delegate, who actually represents the District, is the only exception.
The practical impact varies enormously. Members from states with no individual income tax owe nothing at the state level on their congressional salary. Members from states with top marginal rates above 13% face a significantly larger total tax burden. Two senators with identical salaries and identical federal bills can take home very different amounts depending entirely on which state elected them. Members file state returns and pay whatever their home state’s brackets require, just like any other resident.
What They Cannot Deduct
Maintaining homes in both a member’s home district and the D.C. area is expensive, and tax law used to offer modest relief. For decades, members could deduct up to $3,000 per year in living expenses while in Washington.
The 2017 tax overhaul eliminated that deduction. The statute now reads that living expenses for members of Congress “shall not be deductible for income tax purposes.”9Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses No partial deduction, no cap. Members pay the full cost of dual housing out of their after-tax salary, which is one reason some members sleep in their offices.
Retirement and Investment Income
Members participate in the Federal Employees Retirement System, the same pension and savings framework available to civilian federal workers. Since 2014, newly elected members contribute 4.4% of basic pay toward the FERS defined-benefit annuity, the same rate as other new federal hires.10Federal Register. Retirement: Members of Congress and Congressional Employees
Members can also contribute to the Thrift Savings Plan, which works like a 401(k). For 2026, the maximum employee contribution is $24,500, with an $8,000 catch-up for those 50 and older and an $11,250 catch-up for those between 60 and 63.11Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Traditional TSP contributions reduce taxable income in the year they’re made; Roth TSP contributions don’t, but qualified withdrawals come out tax-free.
When a former member starts drawing a FERS pension, part of each payment is treated as a tax-free return of contributions already paid in. The rest is taxable as ordinary income.12U.S. Office of Personnel Management. Learn More About Taxes and Federal Retirement There is no special pension tax break for former members. Their annuity checks show up on the same 1099-R forms and follow the same IRS rules as any other federal retiree.
Dividends, capital gains, and other investment income get taxed under the same rules that apply to every other investor. Short-term gains on assets held a year or less are taxed as ordinary income; long-term gains and qualified dividends get the preferential 0%, 15%, or 20% rates. What’s different for members is the disclosure layer, not the tax layer. The STOCK Act of 2012 requires them to file periodic transaction reports for any stock, bond, or commodity trade exceeding $1,000, within 30 days of learning about the transaction and no later than 45 days after it occurs.13House Committee on Ethics. Instruction Guide for Financial Disclosure Statements and Periodic Transaction Reports Public reporting doesn’t change the tax treatment.
Outside Income
Members can earn money from teaching, writing, consulting, and similar activities, but their total outside earned income is capped at 15% of the Executive Schedule Level II pay rate. For 2026, that ceiling is $33,855.14House Committee on Ethics. FAQs About Outside Employment Every dollar of outside income is taxable like any other earnings. Members are also flatly prohibited from accepting honoraria, meaning payments for speeches, articles, or appearances.
Office Allowances Are Not Personal Income
House members receive a Members’ Representational Allowance, and senators receive the Senators’ Official Personnel and Office Expense Account. These funds cover staff salaries, office supplies, travel, and the other costs of running a legislative operation.15House Committee on Ethics. Members’ Representational Allowance – House Ethics Manual Because that money pays for government operations rather than personal expenses, it isn’t treated as the member’s taxable income, and it can’t be converted to personal or campaign use. Diverting official funds for personal benefit would make the diverted amount taxable income on top of whatever ethics and criminal consequences followed.
