Interest Rates

Title 32 V.S.A. § 3108 (Establishment of Interest Rate) requires the Commissioner to set the interest rate no later than December 15 each year for the calculation of the interest on the underpayment and overpayment of tax liabilities for the upcoming calendar year. The annual rate for overpayments and underpayments is rounded up to the nearest quarter percent.

The average prime loan rate charged by banks (as determined by the Board of Governors of the Federal Reserve System) for the 12-month period beginning October 1, 2022, and ending September 30, 2023, was 7.78%. Rounding up to the nearest quarter of a percent, the annual rate for the overpayment and underpayment of tax for 2024 will be 8.0%.

This rate will be effective beginning January 1, 2024, and will apply to interest that accrues in calendar year 2024.
