Tax year covered: 2026, filed in 2027. The filing deadline for the 2026 return is 15 April 2027 for most individual filers. The steps below are about what to do when the amount on that return is more than you can pay at once.

Step 1: File on time, even if you pay nothing with the return

This is the single most important step, and it is counter-intuitive. Filing late is punished far more heavily than paying late:

  • Failure-to-file penalty: generally 5% of the unpaid tax for each month (or part of a month) the return is late, up to 25%.
  • Failure-to-pay penalty: generally 0.5% of the unpaid tax for each month (or part of a month) it remains unpaid, up to 25%.
  • When both apply in the same month, the failure-to-file penalty is generally reduced by the failure-to-pay amount, so the combined rate is 5% per month for the first five months.

Filing on time stops the larger penalty immediately. Not filing does not make the tax go away, and it does not stop interest.

Step 2: Pay what you can, when you file

Penalties and interest are calculated on the tax that remains unpaid, so every dollar you pay at filing shrinks the base they run on. A partial payment is not a failed payment. Pay through IRS Direct Pay, EFTPS, or the payment option in your filing software, and keep the confirmation with your tax folder.

Interest is separate from penalties. It accrues from the original due date (15 April 2027 for the 2026 return) until the balance is paid in full, it is set quarterly based on the federal short-term rate plus three percentage points, and it generally cannot be waived or abated. That is why a payment plan does not “freeze” what you owe — it organises how you pay it while interest continues.

Step 3: Ask about a payment plan before the balance grows

The IRS offers payment plans, often called installment agreements, for individuals who cannot pay in full. In general terms:

  • A short-term plan covers a balance you can pay within a short period (the IRS states the current period on its payment-plan page).
  • A long-term installment agreement spreads the balance over monthly payments.
  • If your return was filed on time and an installment agreement is approved, the failure-to-pay penalty rate generally drops from 0.5% to 0.25% per month while the agreement is in effect. Interest still accrues.
  • Eligibility, setup fees and the online application depend on your balance and situation. Check the IRS Online Payment Agreement page for the current eligibility rules before you apply — this article does not state a dollar limit, because that limit can change.

Do not wait for a notice to act. Applying early, while the balance is only tax plus a small amount of penalty and interest, is easier than applying after months of additional charges.

Step 4: If you already have a penalty, ask whether relief applies

Two relief paths exist for failure-to-file and failure-to-pay penalties, not for interest:

  • First-time penalty abatement: if you have a clean compliance history — generally, you filed the same type of return for the three prior tax years and had no penalties in those years — you can ask the IRS to remove the penalty. You must ask; it is not automatic.
  • Reasonable cause: if circumstances outside your control, such as a serious illness or a natural disaster, prevented timely filing or payment, you can explain those facts and ask for relief. Keep any documents that support the explanation.

Neither path guarantees a result. If a penalty is removed, interest charged on that penalty is generally removed with it — interest on the underlying tax itself is not.

What not to do

  • Do not skip filing because you cannot pay. That trades a 0.5% monthly penalty for a 5% monthly penalty.
  • Do not file an extension and treat it as extra time to pay. Form 4868 extends the filing deadline, generally to 15 October 2027 for the 2026 return, but tax owed is still due 15 April 2027. See Your First 1099 Tax Calendar.
  • Do not ignore an IRS notice about the balance. Read it, check the tax year and amount against your return, and respond by the date on the notice.
  • Do not pay a third party that promises to “settle” your tax for pennies without checking the IRS options above first. If your situation involves a large balance, a lien or levy notice, or a prior-year problem, get a qualified professional involved early — that is the situation where professional help pays for itself.

Preventing the same surprise next year

The reason first-timers often cannot pay in April is that nothing was withheld during the year. The fix is not a trick: set aside a percentage of each payment when it arrives, and make estimated payments during the year.
