Yes, our taxes do go to the military. Federal income taxes are the main channel: they flow into the Treasury’s General Fund, and Congress then directs a large share of that pool to national defense. For fiscal year 2026, the Department of Defense requested $961.6 billion, and national defense claims roughly 60% of the discretionary spending Congress votes on each year.1The White House. Fiscal Year 2026 Discretionary Budget Request Not every tax you pay contributes, though. Payroll taxes for Social Security and Medicare, plus all state and local taxes, are legally walled off from the defense pot.
Which Taxes Actually Fund Defense
When the IRS collects your income tax, the money is not sorted into labeled buckets. It pools with other federal revenue in the Treasury, and once deposited, dollars lose their individual identity. There is no tracking system connecting your specific payment to a fighter jet or a soldier’s paycheck. Only after Congress passes spending legislation does any of it get directed toward the military.
Individual income taxes are by far the largest source feeding that pool, accounting for about 52% of all federal revenue so far in FY 2026.2U.S. Treasury Fiscal Data. Government Revenue Corporate income taxes, excise taxes, and customs duties fill in most of the rest. All of it is available for defense appropriations.
Payroll taxes are different. Under 26 U.S.C. § 3101, employees pay 6.2% of wages toward Social Security and 1.45% toward Medicare’s hospital insurance fund, with an additional 0.9% Medicare surtax on wages above $200,000 for single filers or $250,000 for joint filers.3Office of the Law Revision Counsel. 26 USC 3101 – Rate of Tax Employers match the base rates. Those dollars flow into dedicated trust funds and cannot be spent on the military. State and local taxes are entirely outside the federal system and fund schools, police, roads, and other local services.
How Much of the Federal Budget Goes to the Military
The share depends on which slice of the budget you look at, and both common figures are true.
The federal budget divides into mandatory spending, which runs on autopilot under permanent law, and discretionary spending, which Congress must appropriate fresh each year.4U.S. Treasury Fiscal Data. Federal Spending National defense dominates the discretionary side. The White House’s FY 2026 request put total defense discretionary spending at roughly $1.01 trillion out of $1.69 trillion in total discretionary spending, about 60%.1The White House. Fiscal Year 2026 Discretionary Budget Request The FY 2026 defense appropriations bill provides a base discretionary total of $838.7 billion for the Department of Defense specifically.5U.S. Senate Committee on Appropriations.

Zoom out to the entire federal budget, including mandatory programs, and defense accounts for roughly 24% of total spending, behind Medicare and Social Security.6USAspending.

What Your Defense Dollars Buy
Personnel is the largest recurring expense. The military employs roughly 1.33 million active-duty service members, and their base pay, housing allowances, and benefits consume a significant share of the defense budget. The TRICARE health system serves over 9 million beneficiaries, including active-duty members, families, retirees, and Guard and Reserve members.7Defense Health Agency. TRICARE by the Numbers
Beyond payroll, tax dollars fund procurement of tactical vehicles, aircraft, naval vessels, and satellite systems, often under multi-year contracts that lock in billions for programs like stealth fighters or nuclear-powered submarines. Research and development absorbs another large slice, from hypersonic weapons to cyber defense tools. Simply keeping existing hardware running is expensive too: maintenance contracts for aging ships, aircraft, and vehicles consume billions annually.
The military maintains hundreds of installations worldwide, from major bases to small logistics hubs, each requiring construction, staffing, utilities, and security. Fuel costs alone run into the billions; the Department of Defense is one of the largest single consumers of petroleum on the planet. Training exercises, deployments, and transportation layer additional costs on top.
National Security Spending Outside the Pentagon
The DoD budget captures most defense spending but not all of it. Several other agencies handle national security functions funded by federal income taxes.
- Nuclear weapons sit at the Department of Energy. Its National Nuclear Security Administration maintains the stockpile, runs the weapons labs, and builds naval reactors. Its FY 2026 budget request is $30 billion, a 24% jump over the prior year.8Energy.gov. DOE FY 2026 Volume 1 – NNSA Congressional Justification
- The National Intelligence Program, which funds the CIA, NSA, and other intelligence agencies, requested $81.9 billion for FY 2026. Only the topline is disclosed; the detailed breakdown remains classified.9Office of the Director of National Intelligence. DNI Releases FY 2026 Budget Request Figure for the National Intelligence Program
- The Department of Veterans Affairs requested $441.3 billion for FY 2026, including $134.6 billion in discretionary spending. The VA is not part of the defense budget, but its costs are a downstream consequence of military service.10U.S. Department of Veterans Affairs. FY 2026 Budget Submission Budget Highlights
- The State Department’s Foreign Military Financing program provides grants and loans to allied nations for buying U.S. defense equipment. It received $6.2 billion in FY 2026 appropriations.11Democrats House Appropriations Committee. National Security, Department of State, and Related Programs Summary
Add it all up and the true cost of national security significantly exceeds the headline DoD number.
Can You Refuse to Pay the Military Portion of Your Taxes
Some taxpayers, motivated by moral objections to military spending, have tried to withhold the share of their income tax they estimate funds defense. The IRS does not recognize this as a valid reason to reduce or skip payment. Courts have consistently held that allowing individuals to withhold taxes based on disagreements with how the money is spent would impair the government’s ability to function.12Internal Revenue Service. Anti-Tax Law Evasion Schemes – Law and Arguments
The consequences are real even when criminal prosecution is rare. If you file a return but don’t pay, the IRS adds civil penalties and compound interest. Filing a return that includes protest language or claims false deductions to offset “military taxes” can trigger a $5,000 frivolous return penalty under 26 U.S.C. § 6702.13Office of the Law Revision Counsel. 26 USC 6702 – Frivolous Tax Submissions Once the IRS formally assesses what you owe, it can levy bank accounts, garnish wages, and seize property. Taxpayers with seriously delinquent tax debt above $64,000 (as of 2025, adjusted annually for inflation) can also have their passport revoked or renewal denied.14Internal Revenue Service. Revocation or Denial of Passport in Cases of Certain Unpaid Taxes
There is no legal mechanism to direct your tax dollars away from the military. The fungibility of the General Fund makes earmarking at the individual level impossible by design.
Where Accountability Falls Short
The Department of Defense has never passed a comprehensive financial audit. The most recent independent audit of the DoD’s FY 2025 financial statements resulted in a “disclaimer of opinion,” meaning auditors could not obtain enough reliable evidence to form a conclusion about whether the books were accurate.15Department of Defense Office of Inspector General. Independent Auditors Reports on the DoD FY 2025 Financial Statements
The audit identified 26 material weaknesses in internal financial controls. Reporting entities that received disclaimers accounted for at least 43% of the DoD’s total assets, meaning auditors could not verify the existence, completeness, or value of nearly half the Pentagon’s reported holdings.15Department of Defense Office of Inspector General. Independent Auditors Reports on the DoD FY 2025 Financial Statements For taxpayers wondering whether their dollars are well spent, the honest answer is that the Pentagon itself cannot yet fully account for them.
