IRS just announced it will hold fourth quarter interest rates steady for federal tax payments.
According to Revenue Ruling 2021-17, your interest rates as of October 1 will be:
- 2% for overpayments
- 0.5% for the portion of a corporate overpayment exceeding $10,000
- 3% for underpayments, and
- 5% for large corporate underpayments.
That’s the same as it’s been for several quarters now.
