What PAYGO Requires for Federal Budget Discipline

Updated: October 25, 2026

PAYGO requires new legislation that increases mandatory spending or reduces revenue to be offset by savings or revenue elsewhere. It is a budget-enforcement rule, not a guarantee that federal deficits will fall.

That distinction matters: PAYGO disciplines the cost of certain policy changes, while leaving other forces on the budget untouched. Understanding what the rule covers—and how its enforcement works—shows both its value and its limits for federal budget discipline.

• 29% Share of net federal outlays represented by domestic and global health programs and services in FY2023
• $1.9 trillion out of $6.4 trillion Federal domestic and global health program spending compared with net federal outlays in FY2023
• 13% Share of total outlays accounted for by Medicare
• 10% Share of total outlays accounted for by Medicaid and CHIP
• FY1991-95 Period covered by nominal discretionary spending limits under the Budget Enforcement Act of 1990

What does PAYGO require a bill to offset?

Statutory PAYGO requires legislation that cuts federal revenue or increases mandatory spending to offset those changes so the bill does not add to the federal deficit under the applicable budget estimates. The rule applies to tax changes and mandatory programs, not simply to a bill’s overall policy goals.

How the offset works

A tax cut must be balanced by raising revenue elsewhere or reducing mandatory spending. For example, a bill that lowers federal tax receipts would need a revenue increase or a cut to a mandatory program to compensate for that loss.

An increase in mandatory spending must likewise be matched by higher revenue or reductions in other mandatory programs. The practical test is the legislation’s estimated effect on the federal deficit: if its revenue and spending changes leave the deficit higher, the bill has not met statutory PAYGO’s offset requirement.

How does the PAYGO scorecard enforce the rule?

Statutory PAYGO enforces budget discipline by recording the budget effects of enacted laws on scorecards and allowing a sequester to offset a debit. This means the rule looks at legislation’s combined effect, not just whether each bill contains an offsetting provision.

Bill-level offsets

A bill can reduce federal revenue or increase mandatory spending without including enough tax increases or mandatory-spending cuts to cover those costs. If its budget effects are not sufficiently offset, the legislation can add a debit to the statutory PAYGO scorecard.

Cumulative scorekeeping

The scorecard tracks the effects of covered enacted laws together, so an offset in one law can matter alongside costs in another. If the recorded balance shows a debit, the enforcement mechanism can trigger a sequester—an across-the-board cancellation of certain budgetary resources—to offset it.

How is statutory PAYGO different from spending caps?

Statutory PAYGO applies to changes in revenue and direct, or mandatory, spending; discretionary spending caps limit appropriations. The distinction turns on how a proposal is funded: changing an entitlement or tax law engages PAYGO, while funding an agency through annual appropriations falls under the discretionary caps.

The Budget Enforcement Act of 1990 supplemented deficit caps with nominal limits on discretionary spending categories for FY1991-95 and statutory pay-as-you-go rules to discipline direct spending and revenue. These were separate controls within the same law: one addressed annual appropriations, while the other covered legislation affecting revenues and mandatory spending.

• Mandatory spending or revenue: Statutory PAYGO applies when legislation changes entitlement spending or taxes.
• Discretionary appropriations: Spending caps apply to funding provided through annual appropriations.

As a result, the budget control a proposal faces depends on what it changes. A bill that alters an entitlement or tax law is treated differently from one that provides agency funding through appropriations.

How large can the budget stakes be for health programs?

Health outlays in FY2023

Federal health spending was large enough to make changes to major mandatory programs potentially consequential for PAYGO: domestic and global health programs and services accounted for 29% of net federal outlays in fiscal year (FY) 2023, or $1.9 trillion out of $6.4 trillion. KFF reports that breakdown, which includes Medicare, Medicaid and CHIP, and other health spending.

• Medicare: 13% of total federal outlays.
• Medicaid and CHIP: 10%.
• Other domestic health spending: 4%.
• Hospital and medical care for veterans: 2%.
• Global health: 0.1%.

These categories show why legislation changing major mandatory health programs can affect the PAYGO calculation: the rule requires increases in mandatory spending to be offset by savings elsewhere or by additional revenue. The outlay shares provide context for the scale of the programs involved; they do not, by themselves, determine whether a particular bill complies with PAYGO.

When does PAYGO fail to ensure lasting budget discipline?

Limits of the rule

PAYGO does not ensure lasting budget discipline because it constrains only covered legislation, not the federal budget as a whole, and Congress can waive or change its enforcement. The rule requires tax cuts and increases in mandatory spending to be offset, but it does not require Congress to balance all federal revenues and spending.

Statutory PAYGO began in 1990, but enforcement was later waived and the law expired in 2002; deficit-increasing legislation followed. That history shows why compliance with a particular bill is not a lasting guarantee: later legislation can remove the enforcement mechanism or undo offsets.

The distinction is between a bill’s treatment under PAYGO and the rule’s continued force:

• Covered legislation: Tax cuts and increases in mandatory spending must be offset.
• The overall budget: PAYGO does not require Congress to balance all federal spending and revenue.
• Future enforcement: Congress can waive or change the rule, and later legislation can fail to preserve earlier offsets.

What should readers check when a bill claims to be PAYGO-compliant?

Readers should test a bill’s PAYGO claim by identifying whether it changes federal revenues, mandatory spending or discretionary appropriations, then checking what pays for any tax cuts or mandatory-spending increases. Statutory PAYGO applies to changes in revenues and mandatory spending; discretionary appropriations are a separate category.

• Identify the budget effect: Check the bill’s provisions for changes to taxes, mandatory programs or discretionary funding. A claim of PAYGO compliance should be assessed against the changes it actually makes.
• Verify the offsets: Look for tax increases or reductions in mandatory spending that counter the bill’s costs. Savings assumed elsewhere in the proposal are not themselves an offset unless the legislation makes them real.
• Separate the bill from the scorecard: A bill may describe its own offsets, but statutory PAYGO tracks the combined effect of enacted legislation on its scorecard. A bill-level claim does not, by itself, establish that the scorecard remains clear.
• Check enforcement provisions: Read for language that waives, modifies or otherwise changes PAYGO enforcement. Such language can affect what happens even when a bill’s stated offsets appear sufficient.

Frequently asked questions

Key takeaways

• PAYGO requires offsets for tax cuts and increases in mandatory spending.
• Statutory PAYGO scorekeeping is distinct from discretionary spending caps.
• The Budget Enforcement Act of 1990 combined PAYGO rules with discretionary limits for FY1991-95.
• Enforcement can be waived, so compliance does not guarantee lasting fiscal discipline.
