How divorce can affect your taxes in Illinois

On Behalf of | Jul 1, 2026 | Divorce

Divorce can change your household. It may also affect the way you file taxes and the financial decisions you make after your marriage ends.

Those changes often become important as you begin dividing property, planning future expenses and building a new budget. If you are navigating divorce in Illinois, knowing what to expect can make it easier to evaluate settlement terms.

Your filing status could change after your divorce becomes final

The date your divorce becomes final plays a key role in determining your filing status. For federal tax purposes, your marital status on Dec. 31 controls how you file for the entire year. If your judgment is entered on or before that date, you generally must file as single or, if you qualify, head of household.

If your divorce becomes final after Dec. 31, you remain legally married for that tax year. Illinois also follows the filing status used on the federal return.

Spousal maintenance may no longer change taxable income in the same way

Maintenance payments follow different federal tax rules than they did in the past. For divorce judgments entered on or after Jan. 1, 2019, the spouse making payments generally cannot deduct them. Likewise, the receiving spouse does not report those amounts as taxable income. Because of that change, maintenance terms often carry different financial effects during settlement negotiations.

Property division and retirement accounts can create future tax issues

Most couples divide homes, savings or investment accounts during divorce. Those transfers often do not trigger immediate taxes. However, future tax obligations may arise if you later sell property and realize a taxable gain.

Retirement accounts deserve additional attention. Dividing a 401(k) or similar employer-sponsored plan often requires a Qualified Domestic Relations Order (QDRO). Using the proper court order can help preserve tax treatment when the transfer or rollover follows plan and IRS (Internal Revenue Service) requirements.

Planning ahead may reduce costly tax surprises

Tax consequences often continue after a divorce becomes final. Reviewing settlement terms with those financial effects in mind can help you understand how today’s decisions could influence future obligations. Even with that preparation, applying tax rules to your circumstances may not always be straightforward.

An attorney can identify which tax issues need closer review. That support may also help you make informed decisions that align with both your divorce agreement and applicable tax requirements.
