Divorce significantly changes your tax situation, and there are many important steps you need to take. This comprehensive checklist covers everything you need to do after a divorce to ensure your taxes are handled correctly and you're taking advantage of all available benefits.
Immediate Actions After Divorce
1. Understand Your Divorce Date
- December 31 rule: Divorced on December 31 = divorced for entire year

2. Get Your Divorce Decree

3. Update Your Address
If you moved:

Update Your Filing Status
Your filing status changes immediately after divorce.

Head of Household Requirements
To file as Head of Household:
- Unmarried: On December 31

- Benefits: Higher standard deduction ($23,100 vs. $15,400), better brackets

Update Your Withholding
This is critical after divorce.
Why Update Withholding?
- Filing status changes: Single or Head of Household (not Married)
- Income changes: May have different income situation
- Dependents change: May have different number of dependents
- Avoid surprises: Prevent owing money or large refunds
How to Update
- Get new W-4 form: From your employer

- Submit updated form: To your employer
W-4 Considerations
- Single or Head of Household: Choose appropriate status
- Dependents: Account for children you'll claim
- Other income: Include alimony (if taxable), investment income, etc.
- Multiple jobs: Use "Multiple Jobs" worksheet if applicable
Action: Update W-4 form immediately after divorce.
Handle Dependents and Children
This is one of the most important and complex aspects of divorce taxes.
Who Claims the Children?
- Custodial parent: Generally the parent the child lives with more than half the year
- Non-custodial parent: Can claim only with Form 8332 (signed by custodial parent)
- Divorce decree: May specify, but IRS rules still apply
Form 8332
If non-custodial parent will claim:
- Custodial parent signs: Form 8332 (Release of Claim to Exemption)
- Non-custodial parent attaches: To their tax return
- What transfers: Dependency exemption and Child Tax Credit
- What doesn't transfer: Head of Household status, EITC, Dependent Care Credit
Coordinate With Ex-Spouse
- Agree on arrangement: Who claims which children
- Document it: Put agreement in writing
- Avoid conflicts: Only one parent can claim each child per year
- Alternate years: Consider alternating if beneficial
Benefits of Claiming Children
- Child Tax Credit: Up to $2,000 per child
- Head of Household: If unmarried with qualifying child
- EITC: Up to $7,340 for 2 children (if income qualifies)
- Dependent Care Credit: For childcare expenses
Action: Coordinate with ex-spouse and determine who claims each child.
Alimony and Child Support
Understanding the tax treatment is crucial.
Alimony (For Divorces After 2018)
- Not deductible: Alimony paid is NOT deductible
- Not taxable: Alimony received is NOT taxable
- New rule: Applies to divorces finalized after December 31, 2018
Alimony (For Divorces Before 2019)
- Deductible: Alimony paid IS deductible (for payer)
- Taxable: Alimony received IS taxable (for recipient)
- Old rule: Applies to divorces finalized before 2019
Child Support
- Never deductible: Child support is never deductible
- Never taxable: Child support is never taxable
- Always: Regardless of when divorce was finalized
Key Distinction
- Alimony: Spousal support (tax treatment depends on divorce date)
- Child support: Support for children (never affects taxes)
Action: Understand which applies to your situation and plan accordingly.

Frequently Asked Questions
When am I considered divorced for tax purposes?
You're considered divorced for the entire tax year if you're divorced on December 31 of that year.
Do I need to update my W-4 immediately?
