VT Announces Interest Rate on Unpaid and Overpaid Taxes for 2026

The State of Vermont Department of Taxes recently announced that the interest rate on unpaid and overpaid taxes will be 7.75% for 2026.

Pursuant to Vermont statute, the interest rate is calculated based on the average prime rate charged by banks during the preceding 12 months commencing on October 1st of the prior year, rounded up to the nearest quarter percent.  This new interest rate for unpaid and overpaid taxes represents a decrease from the 2025 rate of 8.5%. 

The interest rate will take effect on January 1, 2026, and will apply to interest that accrues in the 2026 calendar year.
