Filing Taxes After Divorce in Mississippi

Your Filing Status Changes the Year the Divorce Is Final

Your marital status on December 31 determines your filing status for the entire tax year. If your Mississippi divorce is finalized any time before midnight on December 31, you file as Single or Head of Household for that year — you cannot file as Married Filing Jointly even if you were married for 11 months of the year.

If the decree is entered on January 2, you are considered married for the prior tax year and may still file jointly for that year (though most divorcing couples choose Married Filing Separately to limit liability exposure from the other spouse's returns).

Head of Household: Who Qualifies

Head of Household filing status offers a higher standard deduction and more favorable tax brackets than Single status. To qualify after divorce, you must meet all three conditions:

• You are unmarried on December 31 (your divorce was finalized before year-end)
• You paid more than half the cost of maintaining a home for the year (rent/mortgage, utilities, food, insurance, property taxes)
• A qualifying person lived with you for more than half the year — typically a dependent child

The parent who has the child for more overnight stays during the tax year claims Head of Household status. This is based on physical custody, not what the decree says about "primary custody." If you share 50/50 custody, one parent must have at least 183 overnights.

Who Claims the Children as Dependents

The custodial parent (the one with more overnights) claims the child as a dependent by default. If your decree assigns the dependency exemption to the non-custodial parent, the custodial parent must sign IRS Form 8332 (Release/Revocation of Release of Claim to Exemption for Child by Custodial Parent) for each applicable tax year.

This is a common source of post-divorce conflict. If your decree specifies that you and your ex alternate claiming the children, keep copies of Form 8332 with your tax records every year.

Mississippi State Tax Filing

Mississippi follows federal rules for filing status on state returns. You will file Mississippi Form 80-105 (individual income tax return) using the same status as your federal return. For 2026, Mississippi's income tax rate is 0% on the first $10,000 of taxable income and 4% on taxable income over $10,000. The Mississippi Department of Revenue lists a $6,000 exemption for Single filers and an $8,000 exemption for Head of Family filers.

If you changed your name as part of the divorce, make sure your Social Security records are updated before filing. A name mismatch between your SSA records and your tax return triggers processing delays.

Property Transfers Between Ex-Spouses

Property transfers between spouses as part of a divorce settlement are generally tax-free under IRC § 1041. This means the quitclaim deed transferring the marital home to one spouse, the car title transfer, and retirement account rollovers via QDRO do not trigger capital gains or income tax at the time of transfer.

The catch: the receiving spouse inherits the original tax basis. If the marital home was purchased for $150,000 and is now worth $300,000, the spouse keeping the home has a $150,000 basis. A future sale may trigger capital gains unless the $250,000 single-filer exclusion (IRC § 121) applies.

Update Your Address With the IRS

If you moved out of the marital home, file IRS Form 8822 (Change of Address) so the IRS sends correspondence and any refund checks to your current address. You should also update your address with the Mississippi Department of Revenue.
