IRS Interest Rates Hold Steady for Q2 2025: What Taxpayers Need to Know

IRS Interest Rates: Starting April 1, 2025, the Internal Revenue Service (IRS) will maintain its interest rates at the same level for the second calendar quarter of the year. This decision affects both individual taxpayers and corporations with regard to overpayments and underpayment.

Key Rates for April 1, 2025

Individuals: Overpayment and underpayment interest rate remains 7%, compounded daily.
Corporations:
- Overpayments: 6% for standard corporate overpayments.
- Excess Overpayments: 4.5% on the amount exceeding $10,000.
- Underpayments: 7% for standard corporate underpayments.
- Large Corporate Underpayments: 9%.

How These Rates Are Determined

Under the Internal Revenue Code, rates are updated quarterly based on the federal short-term rate. The interest rate for individual overpayments and underpayments is the federal short-term rate plus three percentage points. Corporations typically see one percentage point less for overpayments (federal short-term rate plus two), while large corporate underpayments can add up to five percentage points above the short-term rate.

Why It Matters

Cash Flow Management: Taxpayers with outstanding tax obligations or pending refunds should plan around these interest rates to optimize their financial decisions.
Corporate Considerations: Large corporate underpayments carry higher rates, emphasizing the importance of accurate tax calculations and timely payments.
Quarterly Updates: These rates are recalculated every three months, so stay tuned for the next announcement if you have ongoing tax matters.
