Filing Taxes After Divorce: Tax Tips and Deductions for 2025

Taxes after divorce: Filing status

Your marital status as of December 31 controls your tax filing status. So, if you split up, but aren't officially divorced before the end of the year, you can still file a joint return (which is likely to save you money) or choose the married-filing-separately status for the tax return you file for the year you separate.

You can also file as head of household if you lived apart from your spouse for the last six months of the year, file separate returns, had a dependent living with you for more than half of the year, and paid more than half of the upkeep for your home.

Once you are divorced, you can file as a head of household (if you have a dependent living with you for more than half of the year and you pay for more than half of the upkeep for your home) or as a single taxpayer.

Your filing status can have a significant impact on your tax liability. For example, income tax brackets differ for each filing status, and so do standard deduction amounts.

Here are the 2024 standard deduction amounts for each filing status:

• Single or married filing separately: $14,600
• Married filing jointly or qualifying widow(er): $29,200
• Head of household: $21,900

Is alimony taxable?

You can generally deduct alimony you pay to a former spouse if the divorce agreement was in place before December 31, 2018. (If you’re the receiving spouse, you must include alimony or separation payments in your income.)

However, you cannot deduct alimony under divorce or separation agreements that were signed after December 31, 2018. Otherwise, it's not deductible (or taxable to the recipient). You also lose the deduction if the agreement is changed after 2018 to exclude the alimony from your former spouse's income.

To qualify as deductible alimony, the cash-only payments must be spelled out in your divorce agreement. You're required to report the Social Security number of your ex-spouse, too, so the IRS can make sure that your former spouse reports the alimony as taxable income.

Child tax credits after divorce

Generally, only the custodial parent (the one the kids live with most of the year) can claim the child tax credit or credit for other dependents for a divorced couple's qualifying children.

The 2024 child tax credit (for tax returns filed in early 2025) is $2,000 per child 16 years old or younger. Children who are too old for the child tax credit may qualify for the credit for other dependents, which can be as high as $500 per qualifying dependent.

What many people don't know is that it's legal for the noncustodial parent to claim one of these credits for a child if the other parent signs a waiver agreeing not to claim an exemption for that child on their own tax return. That means the custodial parent can't claim the credit. Form 8332 must accompany the noncustodial parent's return each year that they claim the tax credits for the child.

This approach could make financial sense if, for example, the noncustodial parent is in a higher federal income tax bracket than the custodial parent.

Who claims child medical expenses after divorce?

If you continue to pay a child's medical bills after the divorce, you can include those costs in your medical expense deductions even if your former spouse has custody of the child.  However, you must itemize deductions to do so. That means you can't take the standard deduction in the same tax year that you deduct medical expenses.

Additionally, medical expenses are deductible only to the extent they exceed 7.5% of adjusted gross income (AGI), but the child's bills you pay could push you over the 7.5% threshold.

Property transfer after divorce

When a divorce settlement shifts property from one spouse to another, the recipient doesn't pay tax on that transfer. That's the good news.

But it's important to remember that the property's tax basis shifts as well. So, if you get property from your former spouse in the divorce and later sell that property, you will pay capital gains tax on all the appreciation before, as well as after, the transfer. 

That's why, when you're splitting up property, you need to consider the tax basis as well as the value of the property.

What is the exclusion for the sale of a home after divorce?

If, as part of your divorce, you and your former spouse decide to sell your home, the timing can have tax consequences. Normally, the law allows you to exclude tax on the first $250,000 of gain on the sale of your primary home if you have owned the home and lived there at least two years out of the last five. Married couples filing jointly can exclude up to $500,000. For sales after a divorce, if the two-year ownership-and-use tests are met, you and your ex can each exclude up to $250,000 of gain on your individual returns.

If the two-year tests haven't been met, sales of a home after a divorce can still qualify for a reduced exclusion. The limit on tax-free profit would depend on the portion of the two-year period for which the home was owned and used.

If, for example, it was one year instead of two, you each can exclude $125,000 of gain. What happens if you receive the house in the divorce settlement and sell it several years later? Then you're stuck with the $250,000 maximum.

Taxable alimony IRA contribution

Generally, a taxpayer must have earned income from a job or self-employment to qualify to contribute to an IRA. However, there's an exception for some divorced people.

Taxable alimony you receive counts as compensation for the purposes of making IRA contributions. For 2024, you could contribute up to $7,000 to a traditional IRA a Roth IRA, or a combination of the two. The 2025 IRA contribution limit remains unchanged. 

If you're at least 50 years old, you can contribute an additional $1,000 for the year (for a total of $8,000 for the 2024 tax year).
