Finance · Taxes After Divorce
Your marriage ended on a specific date. Your tax return cares about that date more than almost anything else on the form.
Your marital status on December 31 determines how you file for the entire year — even if you were married for eleven months of it and divorced for one. That single fact catches a lot of newly divorced women off guard, and it's the starting point for almost everything else that changes on a tax return after divorce: your filing status, who claims the kids, and how a few specific transactions (the house, retirement accounts, alimony) actually get reported.
Before anything else: tax law is detailed, changes periodically, and interacts with your specific situation in ways a general article can't fully capture. This post explains the general landscape; for your actual return, work with a CPA or tax preparer, especially in the first year after your divorce.
If your divorce was finalized by December 31, you're considered unmarried for the entire tax year and can't file jointly, regardless of how much of the year you were actually married. From there, you're generally choosing between Single and Head of Household. Head of Household requires meeting three things: being considered unmarried, having paid more than half the cost of keeping up your home for the year, and having a qualifying child or dependent who lived with you for more than half the year. If you meet all three, it's almost always worth claiming — it comes with a meaningfully higher standard deduction and more favorable tax brackets than filing Single.
By default, the IRS gives the dependency claim to the custodial parent — defined specifically as the parent the child lived with for the greater number of nights during the year (if the nights are exactly equal, it goes to whichever parent has the higher income). This is true regardless of what your divorce decree says about custody labels; the IRS applies its own night-count definition. If your settlement calls for the noncustodial parent to claim a child in certain years, that's handled through IRS Form 8332, which the custodial parent signs to release the claim for that year. Without a properly filed Form 8332, the noncustodial parent generally can't claim the child, even if your decree says they're entitled to.
This is one of those places where "but the decree says" doesn't automatically translate into "the IRS agrees." Get the actual form filed, every year it applies, rather than assuming the paperwork you already have covers it.
— JenniferIt's worth saying plainly: two parents can't both claim the same child in the same year. If both of you file claiming the same dependent, the IRS will flag the conflict, and it can significantly delay both returns while it's sorted out. If your agreement alternates years, or splits multiple children between you, confirming who's claiming whom before either of you files — not after — prevents an entirely avoidable delay.
For agreements finalized in 2019 or later, alimony is not deductible by the person paying it and not taxable income for the person receiving it — a significant change from how older agreements were treated. Child support, regardless of when the order was issued, has never been taxable to the recipient or deductible by the payer. If your settlement references an older agreement, it's worth confirming which set of rules actually applies before assuming either.
Under current tax law, a single person can generally exclude up to $250,000 of capital gains on the sale of a primary residence, and a married couple filing jointly can exclude up to $500,000 — but this requires meeting ownership and use tests tied to living in the home for a certain period. Divorce creates a specific wrinkle: if one spouse moved out as part of the separation while the other continued living in the home, the spouse who moved out can generally still count toward the "use" requirement, as long as the divorce or separation agreement specifies that the remaining spouse gets to use the home. This detail is easy to miss and can meaningfully affect the tax outcome of selling the house, so it's worth raising directly with a tax professional if a home sale is anywhere in your near-term plans.
A practical next step: gather your final decree, any Form 8332 agreements, and documentation of your home's purchase price and any major improvements before your first post-divorce tax filing — having it organized in advance makes the appointment with your preparer far more useful.
If part of your settlement involved dividing a retirement account through a Qualified Domestic Relations Order, the transfer itself generally isn't a taxable event when it's done correctly through that mechanism — but once you actually withdraw funds from the account later, standard tax rules for that account type apply. This is a good reminder that the paperwork dividing an account and the tax treatment of what happens after are two separate things, both worth understanding rather than assuming one covers the other.
If your tax withholding was set up while you were married — especially if it assumed a joint income, joint deductions, or a spouse's separate paycheck adjustments — it's very likely no longer accurate for your new situation as a single filer or Head of Household. Filing a new Form W-4 with your employer as soon as your filing status changes helps avoid an unpleasant surprise the following spring, whether that's owing more than expected or, less commonly, having too much withheld throughout the year when you could have used that money in your monthly budget instead. This is a five-minute form that's easy to forget in the middle of everything else divorce requires, which is exactly why it's worth doing early rather than waiting until tax season reminds you.
Even if you've always done your own taxes, the first return after a divorce is a reasonable year to bring in a CPA or enrolled agent, simply because there are more moving pieces than usual — filing status, dependency claims, possibly a home sale, possibly a retirement account distribution — happening at the same time you're adjusting to nearly everything else in your life. Getting this one right, with someone who can catch a detail you might not know to look for, tends to be worth the cost — and once things settle into a more routine year, you can always decide whether to keep the help or take it back over yourself.
