If you are required to pay quarterly estimated income tax, an upcoming change in interest rates being imposed by the IRS may have a direct impact on you. Effective April 1, 2022, corporations and self-employed filers who submit quarterly estimated taxes will see a hike in the interest rates that the agency charges for both overpayments and underpayments.

The new rates will be:

  • 4% for underpayments;
  • 6% for large corporate underpayments
  • 4% for overpayments (3% in the case of a corporation)
  • 1.5% for the portion of a corporate overpayment exceeding $10,000

Though these changes will not affect you if you calculate your liability correctly and pay on time each quarter, those taxpayers who have an outstanding balance or who are otherwise out of compliance with their tax obligation need to remember that the longer they take to address the situation, the more their obligation will grow as their liabilities accrue interest at a rate of 3%.
