Filing Taxes After Divorce in Maryland

Your divorce changes everything about how you file taxes — your filing status, your deductions, your credits, and potentially your state tax rate. The rules are strict, and the IRS doesn't care about when your divorce proceedings started — only whether you were legally married on December 31.

The December 31 Rule

Your marital status for the entire tax year is determined by your status on December 31. If your Judgment of Absolute Divorce was entered before December 31, you file as unmarried for the entire year — even if you were married for the first 11 months.

If your divorce was finalized on or after January 1, you and your ex-spouse can still file a joint return for the previous tax year. Whether you should is a different question — joint filing usually results in a lower combined tax bill, but both parties are jointly and severally liable for the entire return.

Your New Filing Status Options

Once divorced, you have two options:

Single. The default status for anyone who is unmarried and doesn't qualify for Head of Household.

Head of Household. Available if you meet all three requirements:

1. You were unmarried on December 31
2. You paid more than half the cost of keeping up a home for the year
3. A qualifying person (typically your child) lived with you for more than half the year

Head of Household gives you a larger standard deduction ($21,900 vs. $14,600 for Single in 2024) and more favorable tax brackets. If you have custody, this is almost always the better filing status.

Immediate Action Items

Update Your W-4

Contact your employer's HR department and submit a new W-4 immediately after your divorce is final. Your withholding was calculated based on your married filing status — without an update, you'll either owe a large balance at tax time or receive a smaller refund than expected.

Change your filing status to Single or Head of Household and recalculate your allowances based on your individual income. The IRS Tax Withholding Estimator (irs.gov) can help you determine the correct withholding amount.

Update Maryland State Withholding

Maryland has its own withholding form (MW507). Update it through your employer at the same time as your federal W-4. Maryland's state income tax rates are progressive, and your county income tax rate varies by jurisdiction — Montgomery County, for example, has a different local rate than Baltimore City.

Child-Related Tax Benefits

If you have children, your divorce decree or custody agreement should address who claims each child as a dependent. Only one parent can claim each child per tax year.

The dependency exemption goes to the custodial parent — the parent the child lived with for the greater number of nights during the year. The non-custodial parent can claim the child only if the custodial parent signs IRS Form 8332 releasing the claim.

Child Tax Credit ($2,000 per qualifying child) follows the dependency exemption — whoever claims the child gets the credit.

Child and Dependent Care Credit can only be claimed by the custodial parent, regardless of who pays for childcare.

Capital Gains on the Marital Home

If one spouse is keeping the marital home, the property transfer itself isn't a taxable event — IRC § 1041 makes transfers between spouses (or former spouses incident to divorce) tax-free.

But when the house is eventually sold, the capital gains exclusion changes. A married couple filing jointly can exclude up to $500,000 in capital gains on a primary residence. A single filer can exclude only $250,000. If the home has appreciated significantly, this reduction can result in a substantial tax bill at the time of sale.

Alimony and Maryland Taxes

For divorces finalized after December 31, 2018, alimony payments are not deductible by the payor and not taxable income for the recipient (under the Tax Cuts and Jobs Act). Maryland follows this federal treatment.

For divorces finalized before January 1, 2019, the old rules still apply: the payor deducts alimony, and the recipient reports it as income. This matters only if your divorce predates the TCJA.

Joint Liability for Prior Years

Even after divorce, both ex-spouses remain jointly and severally liable for any tax returns filed jointly during the marriage. If the IRS audits a prior-year joint return, both parties are on the hook for any additional tax, penalties, and interest — regardless of who earned the income or made the error.

If you believe your ex-spouse understated income or claimed improper deductions on a joint return, you may qualify for Innocent Spouse Relief (IRS Form 8857).

The Maryland After-Divorce Checklist includes a tax transition worksheet that covers W-4 updates, filing status determination, dependency allocation, and a timeline for coordinating with your ex-spouse on any remaining joint filings.
