Best IRS Forms to Know When You Owe

Updated September 2026

If you owe the IRS, the forms that matter most are Form 9465 or the online tool for a payment plan, Form 433-F or 433-A to show your finances, Form 656 for an offer in compromise, Form 12153 to appeal a levy or lien, and Form 2848 if someone will represent you. The rest cover penalties, appeals, innocent spouse claims and transcripts. Revision dates below are the current versions on IRS.gov in September 2026; always download the latest before you file.

1. 1

   Form 9465, Installment Agreement Request

   Form 9465 asks the IRS for a monthly payment plan when you can’t pay in full. The IRS says not to use it if you can pay within 180 days or if you prefer to apply online, and most individuals who owe $50,000 or less in combined tax, penalties and interest can use the Online Payment Agreement instead, at a lower setup fee (2026, per IRS.gov).

   If you’d rather have payments taken from your paycheck, your employer completes Form 2159, Payroll Deduction Agreement. See our installment agreement page.

2. 2

   Form 433-F, Collection Information Statement

   Form 433-F (Rev. 7-2024) is the IRS’s shorter financial statement: bank and investment accounts, real estate, vehicles, employment and household income, and monthly living expenses. Per the Form 9465 instructions (Rev. July 2024), you generally need it when you owe more than $50,000, when you owe $25,000 to $50,000 and won’t pay by direct debit or payroll deduction, or when your proposed payment won’t pay the balance before the collection statute expires.

   That last case is a partial payment installment agreement, which IRS.gov says is reviewed every two years.

3. 3

   Form 433-A, Collection Information Statement for Wage Earners and Self-Employed Individuals

   Form 433-A (Rev. 6-2026) is the longer financial statement, often requested when a revenue officer is assigned or the IRS needs more detail than Form 433-F gives, especially for self-employed people. It covers assets, liabilities, business income and expenses, and household expenses, and it is signed under penalty of perjury.

   Don’t confuse it with Form 433-A (OIC), which is used only for offers in compromise and has its own rules and attachments. Businesses use the matching Form 433-B. Whatever the version, the numbers should match your bank statements, because the IRS verifies them.

4. 4

   Form 656 and Form 433-A (OIC), Offer in Compromise

   An offer in compromise needs Form 656 plus a signed Form 433-A (OIC) for individuals or Form 433-B (OIC) for businesses, all in the Form 656-B booklet (Rev. 4-2026). For 2026, IRS.gov lists a $205 non-refundable application fee and, for a lump-sum offer, 20% of the offer amount paid with the application. Individuals who meet the Low-Income Certification guidelines on Form 656 don’t send the fee or payments.

   If you believe you don’t owe the tax at all, the separate Form 656-L covers doubt as to liability. See our offer in compromise page.

5. 5

   Form 843, Claim for Refund and Request for Abatement

   Per IRS.gov, Form 843 is used to claim a refund or request an abatement of certain taxes, interest, penalties, fees and additions to tax. For people who owe, it is most often the written route for asking the IRS to remove a failure-to-file or failure-to-pay penalty for reasonable cause or first-time abatement.

   Penalty relief lowers the balance you then pay or settle, so it is worth checking before a payment plan or offer. Our penalty abatement page explains the grounds.

6. 6

   Form 2848 and Form 8821, authorizing someone to act for you

   Form 2848, Power of Attorney and Declaration of Representative, lets a person eligible to practice before the IRS, such as an attorney, CPA or enrolled agent, represent you and receive your confidential tax information. Form 8821 is narrower: it lets someone inspect or receive your information but not represent you.

   IRS.gov lets both forms be submitted online. The OIC booklet reminds filers to list every year and form involved, including the current tax year, on the 2848. Without a valid 2848 on file, a representative can’t speak for you on the phone or in an appeal.

7. 7

   Form 12153, Request for a Collection Due Process or Equivalent Hearing

   Form 12153 (Rev. 7-2022) is how you appeal a lien filing or a proposed levy to the IRS Independent Office of Appeals. Per Publication 1660, a CDP request is generally due within 30 days of a levy notice such as the LT11 or Letter 1058, or by the date shown on a lien notice. Late requests can be made as an equivalent hearing within one year, by checking the equivalent hearing box.

   On the form you list your reasons for disagreeing or the alternative you propose, such as an installment agreement, an offer or lien withdrawal.

8. 8

   Form 9423, Collection Appeal Request

   Form 9423 (Rev. 2-2020) is used for the Collection Appeals Program, which covers more actions than CDP: liens, levies, seizures, and rejected, terminated or modified installment agreements. Publication 1660 gives short windows. If a revenue officer is involved, the form must be postmarked within 3 business days after your conference with the Collection manager, and an installment agreement rejection must be appealed by the 30th day after the rejection letter.

   CAP decisions are faster but can’t be taken to court.

9. 9

   Form 911, Request for Taxpayer Advocate Service Assistance

   Form 911 (Rev. 6-2026) asks the Taxpayer Advocate Service, an independent office inside the IRS, to step in. TAS help is free. It can help when an IRS problem is causing financial difficulty, when you’ve tried and failed to resolve an issue through normal channels, or when an IRS process isn’t working as it should. The form doubles as an application for a Taxpayer Assistance Order.

   Describe the problem and the specific relief you want in the form’s section on your tax issue.

10. 10

    Form 8857, Request for Innocent Spouse Relief

    Form 8857 asks the IRS to relieve you of tax, penalties and interest on a joint return when you believe only your spouse or former spouse should be responsible. The instructions (Rev. June 2021) say to file as soon as you become aware of the liability and generally no later than 2 years after the IRS first attempts to collect from you. Equitable relief from an unpaid balance can generally be requested within the collection period.

    Don’t wait for complete paperwork before filing; the instructions say not to delay.

11. 11

    Form 4506-T and online transcripts

    Before choosing any option, pull your IRS transcripts. Form 4506-T requests tax return, tax account, wage and income, record of account and verification of non-filing transcripts, and many individuals can get the same data faster through Get Transcript online. Your account transcript shows assessment dates, which drive your Collection Statute Expiration Date, and the payments and penalties already posted, so you can check a bill line by line.

    You may also hear of Form 4506-C: that is the IVES version lenders use to verify income, not a form for resolving what you owe.

12. 12

    Form 12277, Application for Withdrawal of a Filed Notice of Federal Tax Lien

    Form 12277 asks the IRS to withdraw the public Notice of Federal Tax Lien (Form 668(Y)). Withdrawal removes the public notice, but you still owe the balance. Under the Fresh Start Initiative, IRS.gov describes a withdrawal path for taxpayers who owe $25,000 or less and pay by direct debit installment agreement, if they meet compliance requirements (2026, per IRS.gov).

    If you’ve paid in full, you don’t need this form to get a release: the IRS says it releases a lien within 30 days after payment. Withdrawal and release are different outcomes, so ask which one you are getting.

Which form do you need first?

• You just got a bill and can pay over time: the Online Payment Agreement or Form 9465.
• You received an LT11, Letter 1058 or lien notice: Form 12153, on time.
• You can’t pay at all: a collection information statement, then an offer or a hardship review.
• Someone will help you: Form 2848 first, so they can see your account.
