The IRS recently announced an interest rate increase for the fourth quarter of 2022, starting October 1st. The IRS charges interest for tax underpayments and pays interest on tax overpayments. This includes tax obligations such as estimated taxes and withholdings.

For individuals, the interest rate for overpayments and underpayments will be 6% per year, compounded daily. This is up from 5% for Q3 of 2022.

For corporations, the interest rate will be 5% for overpayments and 6% for underpayments. For corporate overpayments exceeding $10,000, the overpayment interest rate will be 3.5%. And for large corporate underpayments, the interest rate has been increased to 8%.

IRS interest rates are set quarterly and are based on the federal short-term rate from an earlier month. The current change for Q4 was based on the federal short-term rates from July 2022.
