Are Alimony Payments Taxable in Illinois?

Alimony payments in Illinois are subject to tax rules that align closely with federal regulations, primarily depending on the date your divorce or separation agreement was finalized. A significant change in federal tax law impacts whether these payments are taxable to the recipient or deductible by the payor. Understanding these federal guidelines is paramount, as Illinois largely follows the federal treatment of such income.

Federal Tax Rules for Alimony

The Tax Cuts and Jobs Act (TCJA) of 2017 introduced substantial changes to the tax treatment of alimony payments at the federal level. For divorce or separation agreements executed on or before December 31, 2018, alimony payments are generally deductible by the payor and includable in the gross income of the recipient.

However, for agreements executed after December 31, 2018, the tax treatment of alimony reversed. Alimony payments are not deductible by the payor, and the recipient does not include them in their gross income. This shift affects how financial settlements are structured.

For federal tax purposes, “alimony” must meet specific criteria. Payments must be in cash, made under a divorce or separation instrument, and designated as alimony. Additionally, spouses cannot file a joint tax return, and there should be no liability to make payments after the recipient’s death. Payments that are child support, noncash property settlements, or voluntary payments not required by an agreement do not qualify as alimony for federal tax purposes.

Illinois’ Stance on Alimony Taxation

Illinois income tax law largely conforms to federal adjusted gross income (AGI). This means that Illinois generally adopts the federal definition of income and allowable deductions when calculating state income tax.

Consequently, Illinois largely follows the federal tax treatment of alimony. If payments are not taxable federally for agreements executed after December 31, 2018, they are also not taxable in Illinois. Conversely, if the payments are taxable federally for agreements executed on or before December 31, 2018, they remain taxable income in Illinois. Illinois does not impose a separate state income tax on alimony that deviates from this federal treatment.

Important Considerations for Alimony Payors and Recipients

The tax treatment of alimony has financial implications for both payors and recipients, making clear designation in divorce or separation agreements important. Parties should explicitly state whether payments are intended as alimony, child support, or property division to avoid future tax ambiguities. This clarity helps ensure that the agreed-upon financial arrangements align with the applicable tax rules.

Distinguishing between alimony and other financial transfers in a divorce is important for tax accuracy. Child support payments, for example, are never taxable to the recipient nor deductible by the payor. Property settlements are generally not taxable events. These distinctions impact net financial outcomes for both parties.

For pre-2019 agreements, modifications can affect the tax treatment of alimony. If an agreement executed on or before December 31, 2018, is modified after that date, the payments may retain their original tax treatment unless the modification explicitly states that the new TCJA rules apply. Individuals should understand how changes to their divorce or separation instrument could alter taxability and deductibility.
