Bottom line
If you worked in 2025, had children, paid for child care, paid Illinois property tax, or paid certain K-12 school costs, it is worth checking tax credits before you file or fix your return.
For many single mothers, the biggest tax help comes from the federal Earned Income Tax Credit, the Illinois Earned Income Tax Credit, the federal Child Tax Credit, the Additional Child Tax Credit, the Child and Dependent Care Credit, and Illinois credits claimed on state forms.
The regular 2025 tax return deadline was April 15, 2026. If you filed an extension, you may have until October 15, 2026, to file, but the extension did not give more time to pay tax you owed. If you missed the deadline, file as soon as you can, especially if you may be due a refund.
Need help before a tax refund arrives?
A tax refund can help, but it may not come fast enough for rent, food, medicine, child care, utility shutoff, or a court deadline. For urgent local help, call or search 211 Illinois. You can also use ASMOM’s Illinois emergency help page for state and local starting points.
If you have a serious IRS problem causing hardship, contact the Taxpayer Advocate. If you received a tax notice, do not ignore it. Notices often have response dates.
Where to start
This article is written for 2025 tax returns filed in 2026. Rules can change each tax year, so use current official sources.
If you have not filed yet
Gather your income forms, child documents, child care provider information, and Illinois records. Then use IRS Free File, a VITA site, a trusted preparer, or MyTax Illinois for your state return.
If you filed but missed a credit
Do not file a second regular return. Ask a tax preparer, VITA site, IRS, or IDOR whether you need to amend your federal return, your Illinois return, or both.
If another parent claimed your child
Get help before filing. EITC and child tax rules can depend on custody, where the child lived, and filing status. ASMOM’s Illinois child support page may help too.
If you owe tax
File even if you cannot pay in full. Filing can reduce penalties. Then ask the IRS and Illinois about payment options instead of using high-cost refund loans or credit products.
Quick tax credit table for Illinois single mothers
| Credit or help path | What it may help with | Key 2025 rule | Where to check |

| Child and Dependent Care Credit | May reduce federal tax if you paid care so you could work or look for work | You need earned income, qualifying care, and provider information | care credit page |
| Illinois Schedule ICR credits | Property tax, K-12 education expense, and volunteer emergency worker credits | These are nonrefundable and have special limits | Schedule ICR instructions |
Federal and Illinois EITC
The Earned Income Tax Credit is one of the most important tax credits for working parents. It can reduce tax and may create a refund. You usually must file a tax return to get it, even if you were not required to file.
The federal rules are strict. Your income, filing status, investment income, Social Security numbers, and your child’s relationship, age, residency, and joint return status can all matter. The IRS updates the details in its IRS EITC tables.
2025 federal EITC income limits
For 2025 returns, both earned income and adjusted gross income must be below the limit for your filing status and number of qualifying children. The table below uses the main IRS limits for single, head of household, qualifying surviving spouse, and married filing jointly.
| Qualifying children | Single, head of household, or widowed | Married filing jointly | Maximum federal EITC |
|---|---|---|---|
| 0 | $19,104 | $26,214 | $649 |
| 1 | $50,434 | $57,554 | $4,328 |
| 2 | $57,310 | $64,430 | $7,152 |
| 3 or more | $61,555 | $68,675 | $8,046 |
Illinois EITC is different from the federal EITC
Illinois has its own EITC. For 2025, Illinois calculates the credit as 20% of the federal EITC amount or the Illinois expanded EITC amount. You claim it on Schedule IL-E/EITC.
Illinois also has expanded EITC rules. Some people who do not qualify for the federal EITC may still qualify for Illinois EITC, including some ITIN filers and some workers without qualifying children who are age 18 to 24 or age 65 and older.
Example: If your federal EITC or Illinois expanded EITC amount is $1,000, your Illinois EITC would generally be $200 before any part-year or nonresident adjustment. If you also qualify for the Illinois Child Tax Credit, that state child credit is figured after the Illinois EITC.
EITC mistakes that can delay a refund
- Claiming a child who did not live with you for the required time.
- Using the wrong filing status after separation or divorce.
- Forgetting self-employment income, cash income, or 1099 work.
- Entering a Social Security number, ITIN, birth date, or last name wrong.
- Ignoring a letter from the IRS or Illinois Department of Revenue.
If you are not sure who should claim the child, do not guess. Free tax sites, legal aid, and qualified preparers can help. ASMOM’s Illinois legal help page can help when the issue is tied to custody, abuse, or court orders.
Federal and Illinois child tax credits
Federal Child Tax Credit and ACTC
The federal Child Tax Credit is for qualifying children. For 2025, the IRS says the credit is worth up to $2,200 per qualifying child. If you have little or no federal income tax, you may qualify for the Additional Child Tax Credit, which can refund up to $1,700 per qualifying child depending on your income.
Age, relationship, residency, support, dependent status, and Social Security number rules matter. Mixed-status families should get tax help because federal and Illinois rules are not the same.
Illinois Child Tax Credit
The Illinois Child Tax Credit is not the same as the federal child credit. For tax year 2025, Illinois says you qualify if you qualified for the Illinois EITC and have at least one dependent child under age 12 as of the last day of 2025. The credit is 40% of your Illinois EITC.
Example: If your Illinois EITC is $200 and you meet the Illinois Child Tax Credit rules, the Illinois Child Tax Credit would generally be $80. The form does the math. Claim it on Step 5 of Schedule IL-E/EITC.
Child and Dependent Care Credit
If you paid someone to care for your child so you could work or look for work, check the federal Child and Dependent Care Credit. A qualifying person is often a dependent child under 13, but the credit can also apply to some spouses or dependents who cannot care for themselves.
This credit is claimed on your tax return, usually with Form 2441. You must list the provider’s name, address, and taxpayer identification number. If your provider will not give you needed information, ask a free tax site how to handle it.
If child care costs are the bigger problem right now, tax credits may not be enough. See ASMOM’s Illinois child care guide for subsidy and child care assistance options.
Other Illinois credits that may matter
Illinois also has nonrefundable credits on Schedule ICR. Nonrefundable means the credit can reduce Illinois tax you owe, but it will not create a refund by itself beyond your tax liability.
| Illinois credit | Who should check it | Important limit | What to keep |
|---|---|---|---|
| Property Tax Credit | Homeowners who paid Illinois property tax on their main home | Generally 5% of qualifying Illinois property tax paid, subject to rules and income limits | Property tax bill, parcel number, payment proof |
| K-12 Education Credit | Parents or legal guardians who paid qualifying Illinois K-12 expenses | 25% of qualifying expenses over $250, up to $750, subject to rules and income limits | School receipts for tuition, book fees, and lab fees |
| Volunteer Emergency Worker Credit | People awarded a 2025 certificate by IDOR | $500 if awarded, or $1,000 for a joint return if both spouses were awarded | Credit certificate number and copy of certificate |
Renters usually do not claim the Illinois Property Tax Credit unless they also owned and lived in a qualifying Illinois home during the required period. If housing costs are your main stress, see Illinois housing help and Illinois utility help.
Free and lower-cost ways to file
Check free options before paying. Many single mothers can file free online or get free volunteer help.
- IRS Free File: For the 2026 filing season, guided software is available through IRS partners for taxpayers with 2025 adjusted gross income of $89,000 or less. Start at IRS Free File, not through an ad.
- VITA and TCE: IRS-certified volunteers prepare returns for qualifying taxpayers. Use the VITA/TCE locator to find sites.
- IDOR resources: The Illinois Department of Revenue lists free filing and tax preparation options on its IDOR free tax help page.
- AARP Tax-Aide: This program gives free tax help, with a focus on adults over 50 and people with low to moderate income. AARP membership is not required. Search AARP Tax-Aide.
- Ladder Up TAP: In Chicagoland, Ladder Up provides free basic tax return help for eligible residents. Check Ladder Up TAP before going, because sites and limits can change by season.
Tip
Some free software partners include a free Illinois return, and some do not. Read the partner offer before entering all your information. If the site tries to charge you, stop and compare another free option.
If you also need food, cash help, or health coverage, tax filing is only one step. ASMOM has Illinois guides for Illinois SNAP, Illinois TANF, Illinois WIC, and Illinois health care.
Documents and information checklist
Bring or upload complete records. Missing documents are a common reason returns get delayed or credits are missed.
| Category | Bring or collect | Why it matters |
|---|---|---|
| Identity | Photo ID for you and spouse if filing jointly; Social Security cards or ITIN letters for everyone on the return | Names and numbers must match IRS and state records |
| Income | W-2s, 1099s, unemployment forms, self-employment records, cash job records | EITC depends on earned income and adjusted gross income |
| Children | Birth dates, relationship, school or medical records, custody papers if helpful | Credits can depend on where the child lived and who may claim the child |
| Child care | Provider name, address, amount paid, and EIN or SSN | Needed for the Child and Dependent Care Credit |
| Illinois credits | Property tax bill, parcel number, K-12 receipts, credit certificates | Needed for Schedule ICR credits |
| Banking | Routing number and account number, or safe prepaid account details | Direct deposit is usually faster and safer than a paper check |
If the April 15 deadline already passed
For 2025 Illinois individual income tax returns, Illinois says the original due date to file and pay was April 15, 2026. Illinois grants an automatic six-month extension to file, but not to pay. The IRS also says a federal extension gives extra time to file, not extra time to pay.
If you filed a valid extension, use the time to file an accurate return by October 15, 2026. If you did not file or extend, file as soon as you can and ask about payment options if you owe.
Check official deadline details at the Illinois extension page and the IRS extension page.
Watch out for refund loans and surprise fees
Some tax preparers and apps advertise quick refund products. These may be loans, refund transfers, or paid add-ons. They can reduce the money you actually receive. Before you agree, ask:
- Is this a loan or my real IRS refund?
- What is the total fee?
- Can I file free instead?
If a refund is meant to catch up rent or bills, also review Illinois community help and the Illinois assistance guide.
What to do if your refund is delayed, denied, or changed
First, check the refund tracker. Use the IRS refund tracker for your federal refund and Illinois refund tracker for your state refund. Make sure you use official sites, not search ads.
If you receive a notice, read the whole letter. Look for the tax year, the reason, the deadline, and what documents the agency wants. Keep copies of everything you send. If you cannot understand the notice, take it to a VITA site, Low Income Taxpayer Clinic, legal aid office, or a trusted preparer.
Common reasons for changes include income that did not match IRS records, a child already claimed on another return, missing Form 2441 provider details, missing Illinois attachments, or a Schedule ICR credit that IDOR wants to verify.
Backup options while you wait
If the refund delay is affecting rent, utilities, food, or transportation, do not wait for the tax agency to fix everything. Call 211, ask your township or county about emergency help, and check Illinois financial recovery.
