Bottom line
If you are a single mother in New Mexico, your tax return may be worth filing even if your income was low. Check federal EITC, federal child credits, New Mexico’s Working Families Tax Credit, New Mexico’s Child Tax Credit, the Low-Income Comprehensive Tax Rebate, and the state Child Day Care Credit.
For tax year 2025, the federal EITC can be as high as $8,046 for a worker with three or more qualifying children. New Mexico’s Working Families Tax Credit is 25% of the federal EITC. The state child credit can be worth up to $637 per qualifying child for 2025, based on income.
This guide is general information, not tax advice. For an IRS letter, custody issue, ITIN question, or denied credit, use free filing help, New Mexico TRD, or a Low Income Taxpayer Clinic.
Urgent tax help in New Mexico
If you missed the April filing deadline and expect a refund, file as soon as you can. The IRS says there is no federal penalty for filing late when the IRS owes you a refund, but you cannot get the refund until you file. If you may owe tax, file and pay what you can to reduce penalties and interest.
- Use missed deadline steps from the IRS if you have not filed.
- Check federal refund status with Where’s My Refund.
- Check New Mexico refund status with the state refund tracker.
- Call New Mexico Taxation and Revenue at 1-866-285-2996 or use TRD contact.
- For IRS audits, tax debt, or a denied credit, contact the New Mexico Legal Aid tax clinic.
If the tax refund delay is causing a food, rent, utility, or child care problem, also use ASMOM’s 211 guide, bill help, and rent help while you work on the tax issue.
Where to start
Start with the return you need to file for the tax year. In May 2026, most people are dealing with tax year 2025 returns. If you are reading later, check the current IRS and New Mexico forms before using any dollar amount.
If you worked in 2025
Check the federal EITC first. Use the IRS EITC Assistant. Then check New Mexico’s Working Families Tax Credit on your state return.
If you have children
Check the federal Child Tax Credit, the Additional Child Tax Credit, and New Mexico’s Child Tax Credit. Rules depend on age, residency, support, and Social Security numbers.
If you paid child care
Check both the federal care credit and the New Mexico Child Day Care Credit. Keep the provider’s name, address, taxpayer ID, receipts, and any caregiver statement needed by New Mexico.
If income was very low
Do not assume filing is pointless. Refundable credits can still matter. Also check the Low-Income Comprehensive Tax Rebate on the New Mexico PIT-RC schedule.
If you need help before a refund comes, see ASMOM’s real help guide, SNAP guide, child care guide, and housing guide.
Quick tax credit table
This table is a starting point. Your real amount can be lower or zero based on income, filing status, child rules, residency, documents, and whether someone else claims the child.
| Credit or rebate | What it helps with | 2025 tax year amount | Where to claim |
|---|---|---|---|
| Federal EITC | Refundable credit for workers with low or moderate income | Up to $8,046 with three or more qualifying children | Federal Form 1040 and Schedule EIC |
| Federal Child Tax Credit | Credit for qualifying children under 17 | Up to $2,200 per qualifying child; up to $1,700 may be refundable | Federal Form 1040 and Schedule 8812 |
| Federal care credit | Work-related child or dependent care costs | A percentage of up to $3,000 for one qualifying person or $6,000 for two or more | Federal Form 2441 |
| NM Working Families Tax Credit | New Mexico credit tied to federal EITC | 25% of your federal EITC | New Mexico PIT-1 |
| NM Child Tax Credit | Refundable state child credit | Up to $637 per qualifying child, based on income | New Mexico PIT-1 |
| NM rebates and day care credit | Low-income rebate and certain child care costs | Depends on income, household, and expenses | New Mexico PIT-RC |
Federal tax credits to check first
Earned Income Tax Credit
The EITC is for people who worked and had earned income. Earned income can include wages, tips, self-employment, gig work, and some other work income. It does not include child support, unemployment, Social Security benefits, interest, or dividends.
For tax year 2025, IRS EITC tables list maximum credits of $649 with no qualifying children, $4,328 with one qualifying child, $7,152 with two, and $8,046 with three or more. The investment income limit is $11,950 or less.
A child usually must meet age, relationship, residency, and joint-return tests. If a custody order lets the other parent claim the Child Tax Credit, that does not automatically let the other parent claim EITC. Check IRS qualifying child rules when parents disagree.
If you are married but separated, do not guess at filing status. IRS rules may allow EITC for some married filing separately parents who lived apart for the last 6 months or were legally separated. Check IRS EITC rules or use free tax help.
Child Tax Credit and Additional Child Tax Credit
The federal Child Tax Credit helps families with qualifying children. For tax year 2025, the IRS says the credit is worth up to $2,200 per qualifying child. If your federal tax is low, part of it may be refundable through the Additional Child Tax Credit, up to $1,700 per qualifying child, depending on income.
For 2025, the IRS says you, your spouse if filing jointly, and each qualifying child must have a valid work-authorized Social Security number by the return due date, including extensions. Use the IRS IRS child credit page and Schedule 8812 instructions.
Child and Dependent Care Credit
This federal credit can help if you paid for care so you could work or look for work. It may apply to a child under 13, or to a spouse or dependent who cannot care for themselves and meets IRS rules. It is not the same as the Child Tax Credit.
For tax year 2025, the credit is based on a percentage of care expenses. The usual expense cap is $3,000 for one qualifying person or $6,000 for two or more. You must identify the care provider on Form 2441. Use IRS care credit information before claiming a babysitter, relative, or informal provider.
New Mexico tax credits and rebates
Working Families Tax Credit
New Mexico’s Working Families Tax Credit is one of the most important state credits for working single mothers. For recent tax years, New Mexico describes it as 25% of the federal EITC. It is refundable, which means it can increase your refund even if your New Mexico income tax is already zero.
New Mexico’s 2026 filing season notice also says refundable credits can give money back even when taxpayers do not owe taxes and are not required to file. Use New Mexico credits and rebates information and the current PIT-1 instructions.
New Mexico Child Tax Credit
New Mexico has its own refundable Child Tax Credit. The state says the credit may be claimed for each qualifying child as defined by federal tax rules, and the amount changes by adjusted gross income.
For 2025 New Mexico Personal Income Tax, the state lists these credit amounts per child: $637 for income up to $25,000; $424 for over $25,000 up to $50,000; $212 for over $50,000 up to $75,000; $106 for over $75,000 up to $100,000; $79 for over $100,000 up to $200,000; $53 for over $200,000 up to $350,000; and $26 for over $350,000. Check the state NM child credit page before you file or amend.
Low-Income Comprehensive Tax Rebate
The Low-Income Comprehensive Tax Rebate, often called LICTR, is a New Mexico refundable rebate for some low-income residents. New Mexico’s PIT-RC schedule is used for this and other refundable rebates. For 2025 forms, people with modified gross income of $36,000 or less may qualify, but the amount depends on the PIT-RC table and your household information.
Do not skip this just because you had little income. If you are not sure how to complete PIT-RC, use free tax preparation help or call TRD.
New Mexico Child Day Care Credit
New Mexico also has a Child Day Care Credit for some low-income residents who paid child care so they could work. For 2025 PIT-RC information, people with modified gross income of $30,160 or less may qualify. New Mexico forms also point to a Child Day Care Credit Worksheet and a caregiver statement.
This credit has paperwork rules. New Mexico’s day care worksheet says to use it with the PIT-CG caregiver statement when claiming the credit on PIT-RC. Keep receipts and provider information. If your provider will not fill out paperwork, ask free tax help what other records may be allowed before you file.
How to file and get free help
You can file a federal return through IRS Free File if you meet the rules, or use a trusted tax preparer. New Mexico offers online services through TAP account for filing, payments, refunds, and account services. First-year New Mexico filers should read the current instructions.
Free in-person tax help may be available through IRS VITA/TCE sites. The IRS says VITA and TCE prepare basic returns for free for qualifying taxpayers, and the locator is updated during the tax season. Use the IRS VITA locator or call 800-906-9887. AARP Tax-Aide can be found through AARP or by calling 888-227-7669.
New Mexico’s tax agency says CNM Tax Help New Mexico and AARP offer federal and state filing help in the Albuquerque and Santa Fe areas starting in February each year. Check state filing help and local appointment pages. United Way’s Tax Help NM page also lists current income limits and appointment information.
For food, health care, and cash help, see ASMOM’s New Mexico help, WIC guide, Medicaid guide, TANF guide, and school support guide.
Documents checklist
Use this checklist before you file, amend, or call for help. You may not need every item, but missing records can slow a refund or cause a credit to be denied.
| What to gather | Why it matters | Examples |
|---|---|---|
| Income forms | Used for EITC, CTC, state credits, and filing rules | W-2, 1099, gig work records, self-employment income and expenses |
| Child records | Shows the child meets residency and dependent rules | School, child care, medical, benefits, or lease records with address |
| Identity records | Needed for tax filing and credit rules | SSN cards, ITIN letters, photo ID, birth certificates |
| Child care records | Needed for federal Form 2441 and NM child day care credit | Provider name, address, SSN or EIN, receipts, PIT-CG if needed |
| Past returns and letters | Needed for amendments, notices, and refund problems | IRS letters, TRD letters, 2023 or 2024 returns, refund notices |
| Bank information | Direct deposit is usually faster and safer | Routing number and account number from a bank or credit union |
Common mistakes to avoid
- Do not claim a child for EITC just because you paid support. The child usually must live with you for more than half the year.
- Do not split tax benefits by agreement without checking IRS rules. A release to the other parent for the Child Tax Credit is not the same as EITC or child care credit.
- Do not leave self-employment or gig income off the return. EITC is based on earned income, but income must be reported correctly.
- Do not use a child care provider’s made-up number. Wrong provider information can delay or deny the care credit.
- Do not ignore IRS or New Mexico letters. Most letters have deadlines and tell you what proof to send.
- Do not pay a preparer who promises a bigger refund without showing the legal reason. You sign the return, and you are responsible for it.
If something goes wrong
If you already filed and forgot a credit, you may need to amend. The IRS says you generally must file an amended federal return within 3 years after you filed the original return or 2 years after you paid the tax, whichever is later, to claim a refund. Start with the IRS amended return page.
If a federal change affects New Mexico, the state may also need an amended New Mexico return. New Mexico says to use PIT-X for the tax year being amended and to attach federal forms and schedules when the change is tied to a federal amended return. Read the state correcting returns page.
If your refund is delayed, check official status tools first. New Mexico generally processes e-filed refunds within 6 to 8 weeks and paper refunds within 8 to 12 weeks. Identity checks and missing documents can add time.
Backup options while waiting for a refund
A tax refund can help, but it is not emergency income. If you need help before the refund arrives, try the benefit or community program that matches the bill. For safety, custody, or tax problems with an abusive partner, use ASMOM’s legal safety guide and local advocacy programs.
| Need | Better first step | Reality check |
|---|---|---|
| Food | SNAP, WIC, school meals, food banks | Tax refunds can take weeks; food help may be faster. |
| Rent or eviction | Legal aid, 211, housing charities, court help | Do not wait for a refund if you have a court date. |
| Utilities | LIHEAP, shutoff protection, payment plan | Ask the utility about hardship rules before shutoff. |
| Child care | Child care subsidy, Head Start, employer help | A tax credit comes after filing; subsidy help may reduce current costs. |

FAQ
Can I get EITC if I had no income?
No. EITC is based on earned income from work. If you had no earned income, check other benefits and state rebates, but do not claim EITC unless you meet the IRS rules.
Can I claim EITC if I am separated from my spouse?
Maybe. Some married filing separately parents can claim EITC if they meet the IRS separated-spouse rule and have a qualifying child. Use the IRS EITC Assistant or free tax help before filing.
Does New Mexico have its own EITC?
New Mexico has the Working Families Tax Credit. It is tied to the federal EITC and is worth 25% of the federal EITC for recent tax years.
Can I still file if the April deadline passed?
Yes. File as soon as you can. The IRS says there is no federal late filing penalty if you are due a refund, but you must file to receive it. If you owe tax, filing and paying what you can may reduce added costs.
What if I forgot the New Mexico Child Tax Credit?
You may need to amend your return. Check the New Mexico correcting returns page and use the PIT-X form for the tax year you are fixing. Free tax help can help you decide if an amendment is needed.
