What Documents Do You Need to Change Your Filing Status After Marriage or Divorce?
Changing your filing status after a marriage or divorce can affect your tax brackets, credits, withholding, and eligibility for deductions. This checklist explains which documents matter, when to use them, and practical steps to reduce errors and delays. The guidance below references IRS resources and common procedures I use when helping clients make the transition.
Why documentation matters
Accurate documentation shows your legal status and supports claims such as Head of Household or dependency exemptions. The IRS and other agencies may request evidence if they question your return. Keep originals or certified copies and maintain scanned backups for at least three years (longer if your return includes certain credits or business items).
Authoritative sources: IRS guidance on marital filing choices (IRS: Married Filing Status) and amending returns (IRS: About Form 1040-X). See: https://www.irs.gov/individuals/marriage and https://www.irs.gov/forms-pubs/about-form-1040-x. For name/SSN changes, use the Social Security Administration: https://www.ssa.gov/.
Core document checklist (universal)
- Government-issued photo ID(s) for you and your spouse/ex-spouse (driver’s license or passport).
- Social Security cards or Social Security Numbers (SSNs) for you, spouse/ex-spouse, and any dependents. If you changed your name, get an updated Social Security card before filing (Social Security Administration).
- Prior-year tax returns (at least the most recent year) to compare filing choices, deductions, and dependents.
- Proof of address (utility bill, lease, mortgage statement) if the IRS requests residency evidence.
- Bank account and routing numbers for direct deposit or payment.
Documents specific to marriage
- Certified marriage certificate (county or state record). Keep an original or certified copy; photocopies aren’t accepted for some administrative processes.
- Updated Social Security card showing any legal name change (SSA instructions) and updated driver’s license or passport.
- If either spouse was previously married: divorce decrees or death certificates that prove prior marriages ended before this marriage.
- Prenuptial agreement or marital property agreement, if it affects income or asset reporting.
Why: A certified marriage certificate proves your marital status for the tax year. If you and your spouse change your names, update the Social Security record before you file to ensure wages and credits match IRS records.
Documents specific to divorce or legal separation
- Final divorce decree or separation agreement showing the date of divorce or legal separation and settlement terms.
- Child custody, support, or visitation orders (court documents) showing who qualifies to claim a child as a dependent or to use Head of Household status.
- Property settlement papers that clarify who is responsible for specific debts or receives assets; these documents matter when allocating income, gains, or losses.
Why: The divorce decree establishes the legal date of marital dissolution, which affects the filing status for the tax year and who can claim dependents.
Documents relevant to Head of Household claims
If you plan to file as Head of Household, gather:
- Proof of qualifying person(s) relationship (birth certificates, adoption papers, or foster placement documentation).
- Residency evidence showing the qualifying person lived with you more than half the year (school records, medical records, or absentee ballots).
- Court orders or custody agreements that clarify who the child’s custodial parent is for tax purposes.
Note: Head of Household rules carry specific tests the IRS enforces—collect clear documentation before you file. For help understanding qualifying tests, see FinHelp’s guide on Qualifying for Head of Household Filing Status and IRS guidance (https://www.irs.gov/credits-deductions/individuals/head-of-household).

Timing: when to update records and file
- Filing for the tax year: Your marital status on December 31 generally determines your federal filing status for the entire year. If you were married on December 31, you’re considered married for that tax year (IRS: Married Filing Status).
- Midyear changes: If you marry or divorce midyear, update your withholding (W-4) with your employer(s) and notify the Social Security Administration if your name changes.
- Amending a return: If you later discover a different filing status would have been better, you can file Form 1040-X to amend (IRS: About Form 1040-X). Refund claims using an amended return generally must be filed within three years of the original return’s filing date or within two years of when the tax was paid, whichever is later—check Form 1040-X guidance on the IRS site.
Common supporting documents for income and deductions
- W-2s and 1099s for both spouses (or ex-spouses if income was shared or reported jointly during the year).
- Form 1098 (mortgage interest), property tax statements, and loan documents that may be allocated in divorce settlements.
- Records of alimony received or paid (note: for divorces finalized after 2018, alimony treatment changed; check current rules or consult a tax professional).
- Receipts, bills, or records supporting credits and deductions (child care provider information for Child and Dependent Care Credit, tuition statements for education credits, charitable contribution documentation).
Practical steps I recommend to clients
- Update your name with the Social Security Administration first if it changed—your SSN record must match IRS wage records to avoid processing delays (SSA: www.ssa.gov).
- Collect certified copies of marriage certificates or final divorce decrees and scan them into a secure document folder.
- Review prior-year returns with your tax preparer (or tax software) to model whether Married Filing Jointly, Married Filing Separately, Single, or Head of Household yields the best result.
- Update W-4 withholding with employers after marital status changes to avoid under- or over-withholding.
- If you file jointly and later divorce, remember a joint return remains binding for that year unless you amend with Form 1040-X and meet IRS rules. Discuss potential liability with a tax professional.
Common mistakes to avoid
- Filing before updating your Social Security record when you’ve legally changed your name.
- Failing to keep certified copies of marriage or divorce records.
- Assuming the midyear marital status change allows you to split the tax year; federal filing status is generally based on your status on December 31.
- Not documenting custody or residency for Head of Household claims.
If the IRS asks for proof
If the IRS questions your filing status, they typically request specific documents by mail. Provide certified copies where requested and include a cover letter explaining the relevant facts (dates of marriage or divorce, custody arrangements). Keep copies of everything you send and use certified mail or a trackable delivery service.
Record retention and security
- Keep tax returns and supporting documents for at least three years; keep records for seven years if you report a large loss or bad debt deduction. For property or asset records, retain them until the statute of limitations expires for taxes and you can prove basis for capital gains.
- Store scanned copies in an encrypted folder or secure cloud service and retain certified paper copies in a safe or fireproof file.
When to get professional help
Contact a CPA, enrolled agent, or tax attorney if any of the following apply:
- You and your former spouse disagree on who can claim a child or dependency.
- You have complicated property settlements or community property issues.
- You need to amend a joint return after you divorce and are concerned about shared liability.
This is a common situation in my practice: clients benefit from a short consultation to model filing scenarios and identify the minimal documentary proof needed for an IRS inquiry.
