Starting April 1, the new interest rates on overpayments will be:
- 3% for corporate overpayments (1.5% for the portion of a corporate overpayment exceeding $10,000);
- 4% for other overpayments (section 6621(a)(1)).
The new interest rates on underpayments will be:
- 6% for large (over $100,000) corporate underpayments (section 6621(c));
- 4% for other underpayments (section 6621(a)(2)).
