Impact of Tax Credit Extensions on Federal Deficit

The Congressional Budget Office (CBO) has reported to Senator Jeff Merkley (D-OR), who serves as the ranking member of the Senate Budget Committee, that one significant legislative measure, which represents the cornerstone of President Trump’s domestic policy, could potentially increase the deficit by $5 trillion over the next ten years if the temporary tax credit provisions are extended for another decade.

The CBO anticipates that these temporary tax credit provisions, including tax exemptions for wages up to $25,000 and advanced deductions worth $6,000, are likely to become permanent. This shift would consequently add approximately $789 billion to federal obligations in the coming ten years.

Furthermore, the costs related to servicing this debt, estimated at $718 billion, would elevate the total expenses associated with Trump’s initiatives to nearly $5 trillion within a decade.

According to the CBO, the public-held federal debt is projected to rise by 11.5 percentage points by the conclusion of 2034.

“All analysis from the Nonpartisan Congressional Budget Office consistently indicate the same findings, regardless of perspective. This bill will escalate the debt into trillions for the benefit of billionaires’ tax credits,” Merkley stated.

He added, “It’s deeply hypocritical for his party to present itself as financially responsible.”

The CBO compiled this estimate in response to Merkley’s inquiry about the budgetary implications of establishing ten permanent provisions within Trump’s domestic policy legislation set to expire in the coming years.

These provisions encompass advanced deductions, income tax exemptions of up to $12,500 for individuals, $25,000 for joint filers, and tax credits for domestic car loans.

The CBO further informed Merkley that, according to the Tax Commission’s projections, making these ten provisions permanent would result in an additional $78.9 billion in costs over the period from 2025 to 2034.

“This change would lead to a total cumulative impact on the deficit of $5.0 trillion,” the CBO communicated to Merkley.

“Consequently, if there are no alterations to the federal credit program borrowings, the CBO anticipates that public debt will see an increase of 11.5 percentage points by the end of 2034, compared to its January 2025 GDP forecast.”
