<\/span>What\u2019s New for Q1 2026?<\/span><\/h2>\n

The IRS<\/a> decided to keep the interest rate unchanged for the first quarter of 2026 (January 1 to March 31) and same as the fourth quarter of 2025<\/a>, which indicates stability in the underlying federal short-term rates used to compute IRS interest. Here\u2019s how the rates break down:<\/p>\n

\n\n\n\n\n\n\n\n\n\n\n\n
Taxpayer Type<\/th>\nQ1 2026 IRS Interest Rate<\/th>\n<\/tr>\n<\/thead>\n
Individuals \u2013 Overpayments (Refunds)<\/strong><\/td>\n7% per year, compounded daily<\/td>\n<\/tr>\n
Individuals \u2013 Underpayments (Balances Owed)<\/strong><\/td>\n7% per year, compounded daily<\/td>\n<\/tr>\n
Corporations \u2013 Overpayments<\/strong><\/td>\n6% per year<\/td>\n<\/tr>\n
Corporations Overpayments > $10,000<\/strong><\/td>\n4.5% per year<\/td>\n<\/tr>\n
Corporations \u2013 Underpayments<\/strong><\/td>\n7% per year<\/td>\n<\/tr>\n
Large Corporate Underpayments<\/strong><\/td>\n9% per year<\/td>\n<\/tr>\n
IRC 6603 Deposit (Federal Short-Term Rate)<\/strong><\/td>\n4% per year<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

<\/span>How Are the IRS Interest Rates Determine?<\/span><\/h2>\n

With statutory percentage point modifications in accordance with the Internal Revenue Code, these interest rates are computed using the federal short-term rate that was established in the previous relevant month, in this case, October 2025, and rounded to the nearest full percent (4%), resulting in the 7% individual rate currently.<\/p>\n

    \n
  • For underpayments, the rate is the federal short-term rate plus 3 percentage points.<\/li>\n
  • For individual overpayments, it is also the short-term rate plus 3 percentage points.<\/li>\n
  • For corporate overpayments, the “plus-up” is usually only 2 percentage points.<\/li>\n<\/ul>\n

    <\/span>The Impact of Rate Stability on Your Financial Situation<\/span><\/h2>\n

    Making the decision to maintain rates at 7% offers some consistency for 2026 tax planning. However, compared to the 3% rates observed in 2021, 7% is still much greater. This means that 7% interest is applicable if you don\u2019t pay your taxes on time or if the IRS takes longer than 45 days to process your refund.<\/p>\n

    <\/span>Interest Compounding Daily<\/span><\/h3>\n

    Remember that the IRS interest rate is compounded daily. Your principal balance is increased by the interest from Monday to Tuesday, and interest is calculated on the higher amount. So, the small tax debt can increase significantly over several months.<\/p>\n

    <\/span>Understanding the Difference: Individual vs. Corporate Taxpayers<\/span><\/h3>\n
      \n
    • For individual taxpayers, the IRS will charge 7% interest compounded daily on the unpaid amount or the refund you owe. Though interest only starts after a certain time threshold under the IRS rules.<\/li>\n
    • Businesses have a slight change with 6% on regular corporate overpayments and 9% on large corporate underpayments ($100,000), which is costly for companies delaying paying tax bills.<\/li>\n<\/ul>\n

      <\/span>Steps to Avoid Underpayment Interest<\/span><\/h2>\n

      The 2026 filing season starts in late January; here is how to protect yourself from underpayment interest.<\/p>\n

      • E-file accurately to avoid processing delays and increase the risk of interest.<\/li>\n

      • If you can\u2019t pay in full, pay partially to save money and reduce the balances on which the interest is calculated.<\/li>\n
