If you get an IRS tax bill, the short answer is this: read the notice carefully, check the numbers against your own records, and either pay, set up a payment plan, or formally dispute the bill before the deadline printed on it. What to do if you get an IRS tax bill depends mostly on whether the amount is correct and whether you can afford to pay it — but in every case, the worst move is setting the letter aside and hoping it resolves itself.
Read the Notice Before Anything Else
Every IRS tax bill has a notice number in the upper-right corner of the first page. That number identifies exactly why the IRS is contacting you. The most common one for individuals is Notice CP14, sent after the IRS processes a return showing $5 or more owed with no math error involved.1Taxpayer Advocate Service. Notice CP14 – Balance Due $5 or More, No Math Error Businesses get Notice CP161 in the same situation.2Internal Revenue Service. Understanding Your CP161 Notice If the IRS corrected a calculation on your return and that changed what you owe, the notice will be a CP11 instead.3Internal Revenue Service. Understanding Your CP11 Notice
The notice breaks the balance into your original tax, penalties applied so far, and interest that has accrued since the return’s due date. Near the top or bottom of the first page, in a highlighted box, is the total due and a response deadline. Treat that date as hard. Missing it triggers additional penalties and can close off options you’d otherwise have. The notice also lists a toll-free number and the address of the service center handling your case; you’ll need both if you want to dispute or discuss the bill.
Check Whether the Bill Is Correct
Before paying, compare the IRS’s numbers to your own. Pull up the Form 1040 for the tax year on the notice and walk through it line by line against the summary the IRS provided. If the notice says you underreported income, check whether you actually received that income or whether a payer filed an incorrect W-2 or 1099. If a credit was adjusted, check whether you met the eligibility rules and had documentation to back it up.
Gather your W-2s, any 1099s, and records of estimated tax payments or checks you sent to the IRS. The goal is to pinpoint where your figures diverge from theirs. Common trouble spots include adjusted gross income, credit eligibility, and payments that were made but not yet posted to your account.
You can also log into your IRS online account to see balances owed by tax year, up to five years of payment history, and digital copies of notices.4Internal Revenue Service. Online Account for Individuals The online account is especially useful when you believe a payment was made but the notice doesn’t show it.
How to Dispute the Bill
If your records show the bill is wrong, don’t wait for the IRS to catch its mistake. Your options and deadlines depend on the type of notice.
For math error notices like CP11, you have 60 days from the notice date to request an abatement, essentially asking the IRS to undo its adjustment. You can make the request in writing or by calling the number on the notice.5Internal Revenue Service. 21.5.4 General Math Error Procedures – IRM Miss that window, and the IRS can proceed with collection without giving you a formal chance to challenge the assessment in Tax Court.
For larger disputes coming out of a formal examination, you’ll eventually receive a notice of deficiency, sometimes called a 90-day letter. You have 90 days from the date of that notice to file a petition in the U.S. Tax Court, or 150 days if you live outside the United States.6Taxpayer Advocate Service. 90-Day Notice of Deficiency Filing in Tax Court lets you challenge the amount before paying it. Once those 90 days close, that option is gone.
If the IRS files a Notice of Federal Tax Lien or sends a notice of intent to levy, you can request a Collection Due Process hearing by submitting Form 12153 within 30 days of the notice date.7Taxpayer Advocate Service. Collection Due Process (CDP) The hearing, run by the IRS Independent Office of Appeals, lets you propose alternatives like a payment plan or argue the tax itself is wrong. Miss the 30 days and you can still request an “equivalent hearing,” but you give up the right to take the case to court afterward.
How Penalties and Interest Grow While You Decide
Waiting has a price. Two charges run at the same time on an unpaid balance.
The failure-to-pay penalty is 0.5% of the unpaid tax for each month or partial month the balance remains outstanding, capped at 25% of the original amount. On an approved payment plan, that rate drops to 0.25% per month, which is one reason to get on a plan quickly even if you can’t pay in full. If the IRS sends a notice of intent to levy and you don’t pay within 10 days, the rate jumps to 1% per month.8Internal Revenue Service. Failure to Pay Penalty
If your return was also filed late, a separate failure-to-file penalty of 5% per month applies, also capped at 25%.9Internal Revenue Service. Failure to File Penalty When both penalties apply in the same month, the failure-to-file amount is reduced by the failure-to-pay amount, so you aren’t doubled up, but the combined charge still stacks.
Interest accrues daily on the unpaid balance from the return’s original due date. For the first quarter of 2026, the IRS underpayment interest rate is 7% per year, compounded daily.10Internal Revenue Service. Interest Rates Remain the Same for the First Quarter of 2026 The rate is reset quarterly. Interest also accrues on penalties once they’re assessed, which is why older tax debts can grow well past the original amount.
Paying the Balance in Full
If the bill is accurate and you can afford to pay, doing so right away stops both the failure-to-pay penalty and further interest from piling on. You have several ways to send the money:
- IRS Direct Pay is a free electronic transfer from a checking or savings account, with no registration required. You can schedule payments and cancel within two business days.11Internal Revenue Service. Direct Pay with Bank Account
- EFTPS, the Electronic Federal Tax Payment System, requires enrollment and handles more complex payments, including estimated taxes.12Internal Revenue Service. EFTPS: The Electronic Federal Tax Payment System
- Check or money order, mailed with the voucher from the notice. Write your Social Security number (or EIN for businesses) and the tax year on the check so the payment credits the right account.
- Debit or credit card, through IRS-approved processors. They charge processing fees, so this is the most expensive option.
However you pay, keep the confirmation number or canceled check. The IRS occasionally misapplies payments, and a record protects you if collection efforts continue on a balance you’ve already settled.
Payment Plans When You Can’t Pay in Full
If you can’t cover the full balance immediately, the IRS offers two main types of plan. Getting on one sooner cuts the failure-to-pay penalty in half and signals you’re engaging in good faith.
Short-Term Payment Plan
If you can pay the full amount within 180 days, a short-term plan is available with no setup fee. Individual taxpayers qualify if they owe less than $100,000 in combined tax, penalties, and interest.13Internal Revenue Service. Payment Plans; Installment Agreements Interest and the reduced failure-to-pay penalty keep running, but the plan itself costs nothing.
Long-Term Installment Agreement
For balances that need more than 180 days, a long-term installment agreement lets you pay monthly. Individual taxpayers can apply online if they owe $50,000 or less and have filed all required returns.13Internal Revenue Service. Payment Plans; Installment Agreements Setup fees depend on how you apply and pay:
- Direct debit, applied online: $22
- Direct debit, applied by phone, mail, or in person: $107
- Non-direct-debit, applied online: $69
- Non-direct-debit, applied by phone, mail, or in person: $178
Low-income taxpayers, defined as those with adjusted gross income at or below 250% of the federal poverty level, get the direct debit setup fee waived entirely. For non-direct-debit plans, the fee drops to $43 and may be reimbursed when the agreement is completed.13Internal Revenue Service. Payment Plans; Installment Agreements Applying online is cheapest at every income level, and direct debit is cheapest within every application method.
Relief If Paying Would Cause Real Hardship
If paying anything meaningful would leave you unable to cover basic living expenses, the IRS has programs beyond ordinary payment plans.
Currently Not Collectible Status
When the IRS agrees you genuinely can’t afford to pay, it can place your account in Currently Not Collectible status. Collection activity stops, and the IRS won’t levy your wages or bank accounts while the status holds.14Taxpayer Advocate Service. Currently Not Collectible The debt doesn’t disappear, and interest and penalties keep accruing, but it buys time. You apply by contacting the IRS and providing detailed financial information, typically on Form 433-A (for individuals) or Form 433-F. All past-due returns must be filed before the IRS will consider the request.
Offer in Compromise
An offer in compromise lets you settle for less than the full amount if you can show that paying in full isn’t realistic based on income, expenses, assets, and future earning potential. The application requires Form 656, a $205 fee, and an initial payment.15Internal Revenue Service. Offer in Compromise Low-income taxpayers meeting specific guidelines are exempt from both. You must be current on all required filings and estimated payments, and you can’t be in an open bankruptcy. The IRS rejects most offers, evaluating your “reasonable collection potential” against what you propose, so this isn’t a shortcut for people who simply prefer not to pay.
First-Time Penalty Abatement
If your compliance record is clean, first-time penalty abatement can remove the failure-to-file, failure-to-pay, or failure-to-deposit penalty for a single tax period. You qualify if you filed the same type of return for the three prior tax years and had no penalties during that period, or any penalty was removed for a reason other than this relief.16Internal Revenue Service. Administrative Penalty Relief The relief is available regardless of the penalty amount, so it’s worth asking for even on large balances. Request it by calling the number on your notice or writing to the address listed. Interest isn’t abated, but removing the underlying penalty stops interest from accruing on that penalty going forward.
What Happens If You Ignore the Bill
Ignoring a tax bill doesn’t make it go away. The IRS follows a predictable escalation, and each step tightens your finances further.
The first notice is the CP14 or its equivalent. If you don’t respond, follow-up notices arrive over several months, eventually culminating in a CP504, the formal notice of intent to levy your wages, bank accounts, or state tax refund.17Internal Revenue Service. Understanding Your CP504 Notice The CP504 is the final warning before the IRS starts seizing assets.
At any point after the initial demand goes unpaid, the IRS may file a public Notice of Federal Tax Lien. That filing alerts creditors, attaches to your property, damages your credit, and makes it harder to sell property or borrow. If you later set up a direct debit installment agreement and owe $25,000 or less, you can request that the lien notice be withdrawn.18Internal Revenue Service. Understanding a Federal Tax Lien
For larger debts, the consequences reach beyond money. If your unpaid federal tax exceeds $66,000, adjusted annually for inflation, the IRS certifies the debt to the State Department, which can revoke or deny your passport.19Internal Revenue Service. Revocation or Denial of Passport in Cases of Certain Unpaid Taxes Entering into a payment plan or having your account placed in Currently Not Collectible status removes the certification, but processing takes time, so this isn’t something to discover at the airport.
When to Bring in a Professional
Most straightforward tax bills don’t need outside help. You filed, the math checks out, you owe money — set up a payment plan and move on. Certain situations do benefit from a tax professional: an offer in compromise application, a Tax Court petition, a balance that spans multiple years, or any notice proposing changes you don’t understand. Enrolled agents, CPAs, and tax attorneys can represent you before the IRS directly. If you can’t afford representation, Low Income Taxpayer Clinics offer free or low-cost help to qualifying taxpayers, and the IRS maintains a state-by-state list on its website.
