❓ Frequently Asked Questions

Common questions about Illinois spousal support calculations

How is spousal support calculated in Illinois? ▼

Illinois uses a formula-based approach: 33.33% of the payor’s net income minus 25% of the recipient’s net income. However, the total cannot exceed 40% of the combined net income of both parties. Courts also consider factors like marriage length, age, health, and earning capacity.

How long does spousal support last in Illinois? ▼

Duration depends on marriage length: marriages under 5 years typically receive support for 20% of the marriage length, 5-10 years get 40%, 10-15 years get 60%, and 15-20 years get 80%. Marriages over 20 years may qualify for permanent support, especially if the recipient is over 50 or has health issues.

What factors can modify spousal support amounts? ▼

Courts consider: length of marriage, age and health of both parties, earning capacity, standard of living during marriage, contributions as homemaker, education and training needs, property division, child custody arrangements, and any agreements between the parties.

Is spousal support taxable in Illinois? ▼

For divorces finalized after December 31, 2018, spousal support is not deductible by the payor and not taxable income to the recipient under federal law. For divorces before this date, the old tax rules may still apply. Always consult a tax professional for your specific situation.

Can spousal support be modified after divorce? ▼

Yes, spousal support can be modified if there’s a substantial change in circumstances, such as job loss, significant income change, remarriage, or health issues. The requesting party must petition the court and prove the change warrants modification.

What happens if the payor doesn’t pay spousal support? ▼

Non-payment of court-ordered spousal support can result in wage garnishment, asset seizure, contempt of court charges, and other enforcement actions. The recipient can file a motion for contempt or seek other legal remedies through the court system.

Does remarriage affect spousal support? ▼

Generally, spousal support terminates when the recipient remarries. However, cohabitation with a new partner may or may not affect support depending on the specific circumstances and court order terms. Some agreements include specific provisions about cohabitation.

How accurate is this calculator? ▼

This calculator provides estimates based on Illinois guidelines and common factors. However, each case is unique, and judges have discretion in making final determinations. Actual awards may vary based on specific circumstances, local court practices, and individual case factors not captured in this calculator.

⚖️ How Is Spousal Support Calculated in Illinois?

Illinois uses a standardized formula to determine alimony, based on both partners’ income and combined earnings.

📘 Formula (Illinois Maintenance Law)

33.3% of payor’s net income – 25% of payee’s net income = Annual Spousal Maintenance

✅ However, total maintenance cannot exceed 40% of both spouses’ combined net income.

🧮 Example:

Payor’s Income: $100,000
Payee’s Income: $40,000

33.3% × 100,000 = $33,300
25% × 40,000 = $10,000
$33,300 – $10,000 = $23,300/year (~$1,941/month)

Your real calculation may vary depending on marriage duration, child support, and tax factors.
