H.J. Res. 139 proposes a constitutional amendment that would limit annual federal spending and change how Congress raises revenue or exceeds that limit.
The measure requires Congress to enact rules implementing the amendment and delays the amendment’s operation until the fifth year after ratification.
The amendment would reshape fiscal decision-making: by tying spending to recent receipts it would make federal budgets more rigid, raise the bar for tax increases and for statutory exceptions to the cap, and shift fiscal pressure onto program priorities, borrowing practices, and economic stabilization tools. Compliance and enforcement would rest largely with Congress, with significant operational choices left to future implementing legislation.
At a Glance
What It Does
The amendment sets a constitutional cap: annual federal expenditures cannot exceed the average annual receipts of the previous three years, adjusted for population and inflation; it excludes debt-service expenditures and excludes borrowing from receipts. Congress can authorize specific overages by a two-thirds roll-call vote, and can provide exceptions during declared wars. The amendment also requires a two-thirds roll-call approval in each House for any new tax or tax-rate increase.
Who It Affects
The amendment directly affects Congress, the Treasury, federal program managers, and anyone dependent on federal funding—particularly entitlement programs and discretionary grant programs. Financial markets, credit-rating analysts, and states that rely on federal transfers would also face downstream effects from tighter federal fiscal flexibility.
Why It Matters
This would be the first constitutional cap on federal spending, turning a statutory fiscal rule into a structural constraint on budgetary choices. It alters the legislative calculus by embedding a high procedural barrier for tax increases and by making short-term revenue fluctuations directly constrain annual outlays.

What This Bill Actually Does
The core mechanic is straightforward: calculate the limit for any fiscal year by taking the average of the federal government’s receipts over the three prior years, then adjust that number for changes in U.S. citizen population and for inflation. Under the amendment, federal outlays for the year cannot exceed that adjusted average.
Two items are carved out of the arithmetic: payments to service the public debt do not count as expenditures for the cap, and receipts that come from borrowing do not count when computing available receipts.
If Congress wants to spend more than the cap in a given year, Section 2 creates a built-in escape valve: Congress can enact specific expenditures above the limit, but only if two-thirds of each House approve the enabling law by roll-call vote. Separately, the amendment raises the threshold for enacting any bill that: levies a new tax or increases an existing tax rate—those bills require approval by two-thirds of the whole number of each House.
For years when a declaration of war is in effect, Section 3 permits Congress to authorize overages by roll-call vote (the text states that Congress "may by a roll call vote provide by law" for excess spending during war years, without specifying a supermajority in that clause).The amendment does not itself spell out enforcement mechanics beyond a single sentence directing Congress to "enforce and implement this article by appropriate legislation." That means the practical rules—how the cap is calculated in disputed cases, how agencies adjust obligations during a year when receipts fall, or whether courts can enforce compliance—would be left to future statutes and potentially litigation. Finally, the amendment delays going into effect until the fifth year beginning after ratification, giving a multi-year window for states and Congress to adjust before the cap binds.
The Five Things You Need to Know
The spending limit is the average annual receipts from the three prior years, adjusted for changes in the U.S. citizen population and inflation.
Debt-service payments are excluded from the definition of 'total expenditures,' and receipts from borrowing are excluded when calculating receipts.
Congress can authorize specific expenditures above the cap only by a roll-call vote of two-thirds of each House; the text sets a two-thirds threshold for statutory overrides outside war years.
Any bill that levies a new tax or raises a tax rate requires approval by two-thirds of the whole number of each House of Congress to become law.
The amendment would not take effect until the fifth year beginning after three-fourths of the states ratify it, and Congress must adopt implementing legislation to operationalize the rule.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Formula-based annual spending cap
Section 1 defines the constitutional spending cap: annual outlays must not exceed the three-year average of receipts, adjusted for population and inflation. It clarifies two exclusions that materially change the arithmetic: (1) payments for debt service do not count as 'total expenditures' under the cap, and (2) receipts derived from borrowing do not count as receipts. Practically, the section creates a formulaic ceiling that will fluctuate with recent revenue performance and demographic changes, making federal spending procyclical unless policymakers smooth it with other tools.
Two-thirds Congressional override for specific excess expenditures
Section 2 allows Congress to pass laws that authorize specific expenditures above the cap, but only after roll-call approval by two-thirds of each House. That creates a high legislative hurdle for exceptions, meaning that broad or recurring departures from the cap would require sustained supermajority support or frequent special legislation. The provision leaves open whether overrides are project-specific, time-limited, or permanent; those details would come in implementing statutes.
War years exception
Section 3 permits Congress, by a roll-call vote, to authorize expenditures above the cap for any year in which a declaration of war is in effect. Unlike Section 2, this clause does not specify a two-thirds threshold, which suggests a standard roll-call vote (i.e., a simple majority) could suffice; that textual distinction may invite legal and political debate about which voting rule applies during wartime. The provision confines the exception to formally declared wars, not to other military engagements.
Supermajority requirement for new or higher taxes
Section 4 raises the bar for tax legislation: any bill that levies a new tax or increases the rate of an existing tax cannot become law unless two-thirds of the whole number of each House approve it by roll-call vote. This changes the ordinary majority rule for tax bills, shifting the balance between revenue-raising and spending choices and making it structurally harder to use tax increases to meet the constitutional cap.
Congressional implementing authority
Section 5 directs Congress to 'enforce and implement' the amendment through appropriate legislation. The single-sentence grant leaves enormous discretion to Congress—and creates an immediate legislative priority if the amendment were ratified: define calculation methods, create remedies for noncompliance, set transitional rules, and allocate responsibility across Treasury, OMB, and federal agencies. The practical reach of the amendment will therefore depend heavily on these follow-on statutes.
Delayed effective date after ratification
Section 6 delays the amendment’s operation until the fifth year beginning after ratification. That multi-year lag gives a window for statutory implementation and for federal and state actors to prepare, but it also creates a period when the political incentive to enact preparatory statutes may be limited. The delay could also shape fiscal choices made in the interim, including potential attempts to pre-position spending or revenues ahead of the cap’s effective date.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Fiscal-conservative policymakers and advocacy groups: The constitutional cap institutionalizes a rule they favor, converting statutory commitments into a higher-order constraint that is harder to reverse without another constitutional amendment.
- Long-term creditors and markets seeking commitment devices: A binding constitutional rule could be interpreted by some investors as reducing the risk of unchecked future deficits, potentially affecting long-term interest-rate expectations.
- Taxpayers focused on limiting federal outlays: Individuals and groups prioritizing lower federal spending would gain a structural tool that restrains annual budget growth absent supermajority action.
- States and local governments prioritizing predictable federal fiscal posture: Some subnational actors may benefit from clearer federal budget discipline if it reduces abrupt federal funding shifts, though results will vary by program exposure.
Who Bears the Cost
- Federal program beneficiaries (especially means-tested and discretionary programs): Programs funded annually could face tighter caps, scaled back benefits, or increased competition for constrained dollars unless Congress authorizes overrides by supermajority.
- Congress as a policymaker: The amendment raises procedural hurdles and transfers significant authority to supermajority coalitions, limiting the ability of simple-majority coalitions to enact comprehensive fiscal responses.
- Treasury and federal financial managers: The rules change budget execution and cash-management practices; excluding borrowing from receipts but excluding debt-service from the cap creates operational questions about cash flow and debt issuance strategies.
- Agencies with entitlements and mandatory spending: If receipts decline, agencies could be forced into difficult choices about benefit levels, eligibility, or administrative cuts absent legislative relief.
- Tax policy flexibility: Requiring two-thirds approval for new or higher taxes makes it harder to respond to revenue shortfalls, shifting pressure toward spending cuts or creative accounting.
Key Issues
The Core Tension
The amendment pits a legitimate desire for long-run fiscal restraint against the need for flexible, countercyclical, and emergency fiscal policy: locking spending to recent revenues promotes discipline but reduces the federal government's capacity to respond promptly to recessions, natural disasters, pandemics, or other large shocks without needing supermajority support or invoking narrow exceptions.
The amendment embeds several tensions that implementing legislation and courts would immediately confront. First, the cap’s reliance on a three-year trailing average of receipts makes federal spending explicitly sensitive to recent revenue cycles; during recessions receipts fall and the cap tightens, forcing procyclical fiscal contraction unless Congress uses overrides or other stabilizing tools.
Second, excluding debt-service from the cap but excluding borrowing from receipts creates an accounting asymmetry that could be gamed: policymakers might alter the timing or categorization of receipts and outlays to stay inside the letter of the formula while undermining its spirit.
Enforcement is another major open question. The amendment places enforcement responsibility on Congress but does not provide judicial remedies or administrative mechanisms for adjudicating disputes.
If Congress fails to pass implementing rules or if agencies interpret the cap differently, the result could be litigation, inconsistent agency practices, or last-minute fiscal maneuvers. The two different supermajority thresholds—the two-thirds requirement for general overrides and for new taxes versus the unspecified roll-call standard in the war clause—create textual ambiguities that invite strategic behavior and potential constitutional litigation about voting rules and the scope of the war exception.
