EITC and Tax Credits for Single Mothers in Montana

What has changed

• The October 15, 2026 federal and Montana extension dates have passed for most 2025 filers. Late filers need an action plan now, not an extension reminder.
• Tax year 2026 has a higher Montana EITC rate of 20%. The 2025 rate remains 10% for most residents.
• The federal Child and Dependent Care Credit has a higher possible rate starting with 2026 costs. Do not use that newer rate for child care paid in 2025.
• This guide now spells out when a Montana EITC must be reduced and which tax benefits can be split between parents living apart.

Where to start

1. Pick the tax year. Use 2025 rules for 2025 income, even if you file late in 2026. Use 2026 rules for income earned from January through December 2026.
2. Gather all pay records. Include W-2 forms, 1099 forms, cash work, tips, and gig work. Not all money you receive is earned income for EITC.
3. Check the children you can claim. Write down where each child slept during the year. Ask a tax expert if another adult may claim the child.
4. Check your credits. Try the IRS EITC Assistant. Also check child, care, and school credits.
5. File both returns when needed. Montana generally requires a state return if you must file federally and were a resident or had Montana income. You also must file to claim Montana EITC. Check the Montana filing rules if you have low income, live in more than one state, or are unsure.

If you are worried about bills while you file, use the Montana help guide to find benefits and local support. Those programs are separate from tax credits.

Tax credits at a glance

Federal EITC for 2025 income

The EITC helps workers with low or moderate income. It can reduce federal tax and may increase a refund. Earned income can include wages, tips, farm work, household employee wages, and self-employment. Unemployment checks, child support, Social Security, pensions, most interest, and alimony do not count as earned income for this credit. Some special payments have different rules.

Both earned income and adjusted gross income must fit the rules. The chart shows the 2025 upper income limits and highest possible credit. You will not always get the maximum. The first income column also applies to a qualifying surviving spouse or to married filing separately when the special EITC rule is met. If you are married and not filing jointly, you usually need a qualifying child and must meet the IRS separation rule.

For 2025, investment income must also be $11,950 or less. The IRS has rules for the worker’s age if claiming EITC without a qualifying child, and for where the worker lived. A child generally must meet family, age, residence, and tax filing tests. Check the IRS qualifying-child guide rather than guessing.

What can stop an EITC claim?

• Using an ITIN in place of a Social Security number that meets EITC rules.
• Claiming a child who did not live with you for the required time, with no special exception.
• Leaving out cash work, gig income, or self-employment income.
• Using the wrong filing status or missing a past IRS notice.
• Having no qualifying earned income or too much investment income.

If two adults could claim the same child, stop and check before sending a return. The IRS has tie-breaker rules. An agreement between parents does not by itself change EITC residence rules.

Child Tax Credit and Additional Child Tax Credit

For 2025, the federal Child Tax Credit can be up to $2,200 per qualifying child. If your tax is small, you may qualify for the refundable Additional Child Tax Credit, up to $1,700 per child. The actual amount may be lower. The IRS has a calculation on Schedule 8812.

For 2025, a qualifying child is generally under age 17 at year-end, meets the family and dependent tests, and has the required citizenship or residence status. The child must have a Social Security number that meets the new CTC rule. The parent, or at least one spouse on a joint return, must also have the required SSN. If you use an ITIN or a child has another tax number, check the official rules before claiming the credit. The IRS Child Tax Credit page explains these tests.

A child who does not meet the Child Tax Credit rules may qualify for the Credit for Other Dependents. That credit is not refundable, so it may cut tax but not create a refund on its own. The broader ASMOM tax credits and filing guide covers other parent credits.

Child care, school, and other tax help

Care costs when you work or look for work

You may be able to claim the Child and Dependent Care Credit if you paid for care so you could work or seek work. The qualifying person is often a child under age 13, but rules also cover some people who cannot care for themselves. You generally need the care provider’s name, address, and taxpayer number. The credit is not the same as a child care subsidy. See the IRS care-credit rules.

For care paid in 2025, the credit rate ranged from 20% to 35% of allowed costs and was generally not refundable. Starting with 2026 care costs, the highest rate rises to 50%. That can mean a credit of up to $1,500 for one qualifying person or $3,000 for two or more, depending on income and expenses. Those higher figures are for 2026 returns, generally filed in 2027. If you need help with this week’s child care bill, use Montana child care assistance rather than counting on a later credit.

College and training expenses

If you, your child, or a dependent paid eligible college or training costs, ask about the American Opportunity Tax Credit or the Lifetime Learning Credit. These have different student, income, and cost rules. Keep tuition records, Form 1098-T if issued, and proof of eligible costs. Use the IRS education-credit guide. Do not claim the same expense twice. For help paying tuition before filing, check Montana education grants.

Health coverage and other costs

If you bought health insurance through the Marketplace and received help paying premiums, check whether you must file Form 8962 to settle that help with your tax return. The result can change your refund or tax due. Check the IRS Marketplace credit rules. Ordinary rent and utility bills are not general federal tax credits. If you need heat or power now, ask about Montana utility assistance. Ask a tax professional about less common credits such as adoption credits if they apply to your family.

When parents live apart

Do not assume that a court order, child support payment, or agreement about taxes lets someone claim every child-related credit. In most cases, the parent with whom the child lived more nights during the year has the stronger claim under the federal child residence rules.

Under special rules, a parent with custody may sign Form 8332 so the other parent may claim the Child Tax Credit or Credit for Other Dependents, if all rules are met. But that form does not transfer the EITC, head-of-household status, or the dependent care credit. A child may also meet tie-breaker rules when several relatives live together. Use the IRS separated-parents guide and seek tax help if a child was claimed twice.

If the issue also involves a custody order, abuse, or a safety concern, get qualified legal advice. The Montana legal help guide can help you find a starting point. This guide cannot decide who may claim your child.

How to file a 2025 return now

Federal: For most people, the 2025 tax return was due April 15, 2026. People who requested a valid federal extension normally had until October 15, 2026, to file. Both dates have passed. File as soon as you can if you have not filed. If you owe tax, unpaid balances may have penalties or interest, and you may be able to ask about a payment plan. A refund-only federal return usually does not face a late-filing penalty, but the right to claim a refund has a time limit. Some tax relief, military, or disaster cases have special dates. Use the IRS filing hub for current filing methods, or ask a tax clinic.

Montana: The state gives most individual taxpayers an automatic six-month filing extension, with no separate Montana extension form. That did not extend the payment deadline. The usual 2025 extended deadline has also passed. File the state return now if needed and ask about costs or special relief. The Montana extension guide covers the rules, including military exceptions.

Free filing: IRS Free File guided software for 2025 returns was offered to those with 2025 adjusted gross income of $89,000 or less, but its normal 2026 filing season closed October 15. Do not assume it is still taking 2025 returns. The IRS free filing page lists available options. Also check Montana filing options. Ask a VITA site whether it is open and can handle a late return. Some complex returns need a trained tax specialist.

Use the free Montana TAP portal to manage state tax information, payments, or refund checks. Use your own secure login. Do not give your password to an unknown preparer.

Can you still claim an old refund?

Often yes, but the law sets time limits. The federal refund-claim rule generally looks at when you filed and paid, and extensions and special relief can matter. The IRS refund deadline guide explains this. Do not assume every past-year refund remains available. Ask for help promptly if you did not file an older return.

When to expect a refund

The IRS cannot issue a refund based on EITC or ACTC before mid-February of the normal filing season. That rule applies to the whole federal refund, not just those credits. It does not mean the IRS holds every EITC refund until a fixed date later in the year. See the IRS EITC refund guide. A return filed months late can have its own timing.

Montana says a state refund can take up to 90 days to issue, and some cases take more time if the state must check an error or identity. The state refund status page says online status may appear about two weeks after e-filing, or about 18 weeks after mailing a paper return. First-time Montana filers get a paper check, not direct deposit. An offset may also take part of a refund to pay some government debts.

If you get a Montana identity-check letter, follow its steps. If more than 90 days have passed with no clear answer, contact Montana Revenue. Keep your tax return, refund amount, dates, and any letter close at hand.

Documents to gather before filing

Take copies or secure photos of the records you give a preparer. Save copies of the final signed returns and proof of filing. If you cannot find a W-2 or other record, ask the payer for a copy and tell the tax preparer what is missing.

If your credit is denied, delayed, or questioned

1. Read the notice. Write down the notice number, the year, and the reply date. IRS and Montana letters do not all use the same deadline.
2. Check the reason. The problem may be child residence, income records, a tax number, a return error, identity checks, or a debt offset.
3. Gather proof. Use school records, child care bills, pay records, tax forms, and other records the notice calls for.
4. Reply the way the letter says. Keep copies, proof of mailing or upload, and the name of anyone who helped you. Do not send original documents unless asked.
5. Get help before the deadline. If the issue is complex, ask a tax clinic, qualified tax preparer, or attorney. Do not assume a benefits office can handle tax appeals.

If the IRS denied or cut your EITC, CTC, ACTC, Credit for Other Dependents, or American Opportunity Tax Credit in an earlier year for a reason other than a math or clerical error, you may need Form 8862 guidance before you claim that credit again. If someone may have filed in your name, the IRS IP PIN service can help protect later returns.

For an error that led to a missed credit, ask whether you need an amended return. Do not send a second original return unless the agency says to. Check each notice’s appeal or response rights. Montana tax objections and IRS appeals follow their own rules.
