IRS Tax Liability Guide

IRS Tax Liability Guide

Last reviewed October 2026Reviewed by Safwan Al-Sayyad, Global Gate Tax and Accounting

Short answer

If you owe the IRS, the balance grows with penalties and interest until it is paid, and unpaid balances move through a fixed series of notices toward levy. Most people can stop that path with a payment plan, an offer in compromise or hardship status. Start by confirming the exact amount in your IRS Online Account, then match your notice to the options below.

Key takeaways

  • The IRS generally has 10 years (IRS.gov, 2026) from assessment to collect a balance, and interest runs the whole time at the federal short-term rate plus 3 percentage points (IRS.gov, 2026).
  • Notices escalate in a set order. The final notice of intent to levy starts a 30 days (IRS.gov, 2026) window to ask for a Collection Due Process hearing.
  • Individuals who owe $50,000 (IRS.gov, July 2026) or less can usually set up a Simple Payment Plan online, without financial statements.
  • Collection can be paused while a payment plan or offer is pending, but interest does not stop.
  • You can handle many cases yourself through IRS.gov. Free help exists through the Taxpayer Advocate Service and Low Income Taxpayer Clinics.

How to use this guide

The guide follows the order most people need it in. First, figure out what is happening and how serious it is. Then compare the ways out. Then act, either on your own or with help. Each page links to the IRS sources behind it, and every IRS figure shows the date we last checked it.

  1. Find your notice. The notice number is in the top or bottom right corner of the letter (for example CP14, CP504 or LT11). Look it up in the table below.
  2. Confirm the amount. Sign in to your IRS Online Account to see the balance by year, payments and any payment plan. Treat any letter that does not match your account with suspicion.
  3. Check your deadline. Most notices give a response date. A final notice of intent to levy and a notice of deficiency have legal deadlines you cannot get back once missed.
  4. Pick a path. Use the options section to see which IRS programs fit your balance and your ability to pay.

Find your IRS notice

The IRS sends collection notices in a set order. The later your notice sits in this table, the less time you have and the more the IRS can do on its own.

Understand what is happening

A balance due is not a one-time bill. The failure-to-pay penalty adds 0.5% (IRS.gov, 2026) of the unpaid tax for each month or part of a month, and the failure-to-file penalty is 5% (IRS.gov, 2026) per month when a return is late. Interest is charged on both the tax and the penalties. That is why the same balance looks larger on each notice.

If you do nothing, the IRS moves from letters to enforcement. It can file a federal tax lien, which is a public claim against your property, and after the final notice it can levy wages, bank accounts and some federal payments. Unpaid balances over $66,000 (IRS.gov, 2026) can also be certified to the State Department, which can deny or revoke a passport.

Compare your options

Which option fits depends on three things: how much you owe, what you can afford each month, and whether all your returns are filed. Balance size alone decides a lot. Individuals who owe $10,000 (IRS.gov, July 2026) or less have a guaranteed installment agreement if they meet its conditions, and at $50,000 or less a Simple Payment Plan needs no financial statement. Above that, the IRS looks at your income, expenses and assets.

Payment plan You can pay the full balance over time IRS payment plans
Offer in compromise You cannot pay in full before the collection statute ends Offer in compromise

Levies by type, and tools

The rules for a levy depend on what the IRS is taking. These guides cover each type, and the calculators help you check dates and amounts yourself.

Guides by situation

Why a balance builds up, and which option fits, often depends on your work and what is happening in your life. These guides apply the same IRS rules to specific situations.

Get it handled

Many people resolve an IRS balance on their own. If you owe $50,000 or less, are current on filing and can pay over time, the IRS Online Account is often all you need. Free help is available from the Taxpayer Advocate Service when an IRS problem is causing hardship, and from Low Income Taxpayer Clinics if your income qualifies.

A professional is worth considering when a levy is active or a final-notice deadline is close, when the balance is above the Simple Payment Plan limit, when you have several unfiled years, or when a business owes payroll taxes.

Already have a final notice? The window to request a Collection Due Process hearing is 30 days from the date on the letter. Read the 30-day action plan today.
