Interest rates are adjusted on a quarterly basis and are determined by the federal short-term rate plus three percentage points. Interest paid on late tax payments is not deductible.

2022 Q4 interest rates are:

  • 6% for overpayments (5% for corporations)
  • 5% for the portion of a corporate overpayment exceeding $10,000
  • 6% for underpayments
  • 8% for large corporate underpayments

Arizona is among the many states that follow the federal interest rate. The Arizona Department of Revenue applies interest, compounded annually, in the same manner and at the same time as the Internal Revenue Code.

With inflation still in the news and the Federal Reserve not quiet about their plans to keep hiking rates, the moral of the story is pay your taxes on time. It’s getting more and more expensive to not.
