EITC and Tax Credits for Single Mothers in Arizona

Where to start

1. Check the federal EITC: If you had wages, tips, or self-employment income during 2025, use the IRS EITC Assistant. It checks more than income.
2. Check child credits: A child younger than 17 at the end of 2025 may count for the Child Tax Credit. Other dependents may qualify for a different, nonrefundable credit. Review the IRS child credit rules.
3. Check Arizona credits: Use the Arizona tax credit guide and the 2025 form instructions.
4. Choose a filing route: If you missed October 15, see the late-filing section below. Ask if a free volunteer site can still take your 2025 return.

Our tax assistance guide explains common tax terms and free help for parents. Our Arizona family help guide covers support beyond tax credits.

Quick reference: Which credit fits?

Refundable means a credit may give you money back even when the tax you owe is low. Nonrefundable means it usually lowers tax owed but cannot by itself make a refund. Tax credit and tax deduction are different.

Federal tax credits Arizona families should check

Earned Income Tax Credit (EITC)

The EITC, also called EIC, helps some workers with low or moderate incomes. Wages, tips, gig work, and net earnings from your own business may count. Child support, unemployment pay, Social Security, pensions, and investment earnings are not earned income for this credit. Some disability payments have special rules, so ask before deciding they count.

These are the 2025 tax-year maximums from the IRS EITC tables. The dollar figures are ceilings, not promised refunds. Both earned income and adjusted gross income tests apply.

The 2025 investment income cap is $11,950. You and each child used for EITC generally need a valid Social Security number issued by the return due date, including extensions. A qualifying child also has age, family relationship, and residency rules. An unmarried parent is not automatically the one who can claim the child.

If you are married but living apart, IRS Publication 596 explains the limited situations where you may still claim EITC without filing a joint return. Do not choose “single” only because you live alone. Ask a VITA worker when your legal marital status or custody situation is not clear.

Child Tax Credit and Additional Child Tax Credit

For 2025, the Child Tax Credit (CTC) is up to $2,200 for each eligible child younger than 17. The refundable Additional Child Tax Credit (ACTC) may be up to $1,700 per child if you meet the earned-income and other tests. ACTC usually requires at least $2,500 of earned income. The Credit for Other Dependents may help for an older child or another dependent, but it is not refundable.

For 2025 CTC and ACTC, the child must have a work-valid Social Security number issued by the deadline. The person claiming the credit must also meet the new 2025 Social Security number requirement. On a joint return, one spouse needs a work-valid SSN and the other needs an SSN or ITIN issued on time. The 2025 Schedule 8812 instructions explain exceptions and how to calculate the credit.

For most cases, the child must live with you for more than half the year and be claimed on your return. If two people claim one child, IRS rules decide who may take each credit. A divorce order or child support payment alone does not settle EITC rights. In some cases, the parent the child lived with may sign IRS Form 8332 so the other parent can claim CTC. That release does not transfer the right to claim EITC. Our child tax credit guide gives a wider overview. The rule that EITC or ACTC refunds cannot go out before mid-February mattered early in the 2026 filing season; it is not a new October waiting period.

Child and Dependent Care Credit

This credit may lower 2025 federal tax if you paid for care so you could work or look for work. It usually covers a qualifying child younger than 13, but some people who cannot care for themselves may qualify at older ages. You need the care provider’s name, address, and tax ID. Not all family members can be paid providers for this credit.

Use 2025 Form 2441 instructions. The 2025 federal credit is nonrefundable. Do not use the higher 2026 rates when fixing a 2025 return: the IRS child care credit page says the higher rates begin in tax year 2026, generally filed in 2027. If you need help paying for care now, see our Arizona child care help guide.

Premium Tax Credit

If your family bought health insurance through HealthCare.gov in 2025, look for Form 1095-A. You may need to use Form 8962 instructions to compare the advance premium tax credit paid for your plan with the amount you qualified for. You may owe some money back if too much was paid in advance. For 2025, repayment limits may apply in some cases.

For 2026 coverage, the IRS premium credit guidance says the excess advance-credit repayment cap no longer applies. That is a different tax year. If your income or household changes, update the Marketplace rather than hoping it will sort itself out at tax time.

Education credits

If you or your child attended an eligible college or trade school, ask about the American Opportunity Tax Credit (AOTC) or Lifetime Learning Credit. The AOTC can be partly refundable in some cases. Keep Form 1098-T and receipts for eligible school costs. The IRS education credit guide explains rules for school years, enrollment, income, and expenses. Do not claim the same education costs for two tax benefits.

Arizona tax credits to check

Arizona credits are separate from federal EITC. Most Arizona credits reduce your state tax; some are refundable. Use the right form for 2025 and answer the credit questions even if your tax bill seems small.

Arizona Dependent Tax Credit

The 2025 Arizona Form 140 booklet uses $100 for each dependent under age 17 and $25 for each other dependent, before any high-income phaseout. Arizona asks for names, identifying numbers, relationships, and months lived with you. Some recent online law text shows a different amount; do not copy a later-year figure onto a 2025 return. Ask ADOR or a tax preparer which year’s rule applies.

Arizona Family Income Tax Credit

Arizona’s Family Income Tax Credit is for some households with very low income. Under Arizona law 43-1073, it is $40 for each eligible Arizona resident listed on the return, up to $240 for head-of-household or married joint filers, or $120 for single or married-separate filers. Income limits depend on filing status and number of dependents. This is a nonrefundable credit: it cannot be larger than your Arizona tax due.

Arizona Increased Excise Tax Credit

Some low-income Arizonans may get a credit of $25 per qualifying person, up to $100 per household. The Arizona Form 140ET page lists 2025 income tests, including federal adjusted gross income no greater than $25,000 for a head of household or joint filers, and $12,500 for single or married-separate filers, plus other limits. A person claimed as someone else’s dependent cannot claim it. Some who do not otherwise need an Arizona return can use Form 140ET. Use the credit worksheet in your own filing form or ask ADOR whether Form 140PTC is the right route.

Arizona Property Tax Credit

Arizona’s Property Tax Credit is not for every renter or homeowner. It may fit a person who lived in Arizona all year, paid rent or property tax on a main home, met very low household income limits, and was age 65 or older by year-end or received the qualifying Supplemental Security Income specified by ADOR. This can matter to some grandmothers raising children or mothers who meet the SSI rule. ADOR lists household income under $3,751 if you lived alone, or under $5,501 otherwise. Read the ADOR eligibility summary and Form 140PTC for full rules and filing timing.

Donation-based Arizona credits

Arizona has state credits for some gifts to approved charities, foster care groups, public schools, and school tuition groups. These are not benefit checks and do not usually help if you owe no Arizona income tax. ADOR says a qualifying donation made by April 15, 2026 may count on a 2025 return even if filed later. Gifts made after that date do not become 2025 gifts simply because the return is late; read Arizona’s tax-season FAQ. Never donate money needed for rent or groceries solely to seek a tax credit.

How to file a 2025 return now

October 15, 2026 has passed. The IRS says its 2025 Free File guided service and Fillable Forms were available through that date. Do not promise yourself that a closed seasonal site will still accept a 2025 return. The IRS filing steps describe other ways to file; ask a free tax site whether it can prepare and file an overdue 2025 return. Arizona also has a free-filing information page, but each software provider sets rules and seasonal access. The old FileYourStateTaxes service closed October 31, 2025 and did not return for the 2026 filing season. Do not follow old Direct File instructions for Arizona.

The IRS VITA/TCE locator lists free help. VITA focuses on many lower-income filers, people with disabilities, and people who need language help. The IRS does not set one income cap for all sites; ask the location about its rules. Some sites are seasonal. Local leads include Phoenix VITA and Pima County VITA; call before making a trip.

If you owe taxes, file even if you cannot pay everything. The extension did not extend the April payment deadline. The IRS late-filing guidance explains penalties, interest, and payment choices. If you expect a refund, filing late may still be possible, but refund claims have time limits. Ask for help before you lose a refund or credit. Check disaster relief or special filing rules if they affect you.

Documents checklist

Keep copies of these items. Take both parents’ or children’s records only when they are needed for your claim. Never send Social Security numbers or tax forms through an unverified email or text link.

• Identity: Photo ID; your SSN or ITIN document; SSN cards or approved identification for people on your return; prior return if available.
• Income: W-2, 1099, tips, unemployment forms, and records of cash or gig work, sales, mileage, and business costs.
• Child’s home: School, child care, health, lease, or benefit records that may show where the child lived if disputed.
• Child care: Provider’s legal name, mailing address, taxpayer ID, and payment proof.
• Health and school: Marketplace Form 1095-A, school Form 1098-T, tuition bills, and covered school receipts.
• Arizona claims: Donation receipts, rent or property tax papers, Arizona tax notices, and any Form 140PTC records.
• Refunds and notices: Safe bank details for direct deposit, letters, dates, and copies of returns sent.

For gig work, write down business income and real business costs before claiming EITC. If you are building a small business, our Arizona business resources guide also covers business records and local advisors. Business grants are not the same as tax credits.

What to do if your refund is delayed or a credit is denied

1. Check the correct tracker. The IRS refund tracker guide explains when a return may show up. The Arizona refund checker is for state refunds. A submitted return is not the same as a refund approved for payment.
2. Read every notice. Note whether it is about a missing form, a credit check, identity theft, or a refund offset for debt. Check the response deadline and write down what proof is requested.
3. Fix only what needs fixing. If income, dependents, or credits were wrong, the IRS amended-return guidance helps you decide whether Form 1040-X is needed. Do not submit a second original return just because the first is slow.
4. Ask about credit denials. If EITC, CTC, ACTC, the Credit for Other Dependents, or AOTC was disallowed, you might need Form 8862 before you can claim it again. Read Form 8862 instructions; there are exceptions based on why the claim was denied.
5. Get help with a contested child claim. If someone else claimed your dependent, use the IRS dependent identity-theft guidance. Save school or medical records. A free tax clinic or qualified advisor can help you respond.

An IRS refund may be reduced for certain overdue debts, such as federal tax or some child support debts. If you believe the offset is wrong, follow the notice’s contact and appeal instructions. Do not miss an appeal window while calling a general help line. For Arizona account questions, use the official ADOR contact page.
