How Disability Tax Credits Work and Who Can Claim Them

What disability tax credits are and how they reduce what you owe

A disability tax credit is a federal tax benefit that lowers your income tax bill if you or a dependent has a severe and prolonged impairment. The credit does not pay you money directly — instead, it reduces the amount of tax you owe, or increases a refund you are due. The two main programs are the Earned Income Tax Credit (EITC) for working people with lower incomes, and the Child Tax Credit for families with children, both of which have disability-related provisions.

The amount you receive depends on your income, your filing status, and which credit you claim. Because these are federal credits, they work the same way regardless of what state you live in, though some states offer additional disability-related tax breaks on top of the federal ones.

Key Takeaways

• The Earned Income Tax Credit can add hundreds to thousands of dollars to your refund if you work and earn below a certain income threshold, which varies by filing status and number of dependents.
• The Child Tax Credit provides up to $2,000 per child under 17, and families with disabled children may be able to claim it even if their income is higher than the standard limit.
• You do not need a formal disability diagnosis to claim these credits — you need proof that an impairment substantially limits a major life activity and is expected to last at least 12 months.
• The IRS does not require you to register as disabled or file a separate disability application; you claim the credit on your tax return using Form 1040 and supporting schedules.
• State tax returns often have their own disability credits separate from federal ones, so check your state's tax authority website to see what additional credits may be available.

The Earned Income Tax Credit for workers with disabilities

The EITC is a refundable credit, meaning that if the credit is larger than the tax you owe, the IRS sends you the difference as a refund. In 2024, the maximum credit ranges from about $600 for a single person with no children to about $3,900 for a married couple filing jointly with three or more children. The exact amount depends on your earned income — the credit phases out as your income rises, and the income limits vary by filing status and number of dependents.

To claim the EITC, you must have earned income from work (wages, self-employment, or farm income). You file using Schedule EIC attached to your Form 1040. The IRS does not require proof of disability to claim the EITC; instead, you report your income and filing status, and the credit is calculated based on those factors. However, if you have a dependent with a disability, that can affect how much you receive, because the credit is larger for filers with children.

Many people claim the EITC without realizing they are may have access to to it. If your income is low to moderate and you worked during the year, you can check whether you may have access to by using the IRS EITC Interactive Tax Assistant on the IRS website, or by asking a tax preparer.

The Child Tax Credit for families with disabled children

The Child Tax Credit provides up to $2,000 per child under age 17. Normally, the credit begins to phase out when your income exceeds $400,000 (for married couples filing jointly) or $200,000 (for single filers). However, if your child has a disability, you may be able to claim the credit even if your income is above these thresholds, depending on the specific circumstances and the year you are filing.

To claim the credit, you list your child's name, date of birth, and Social Security number on Schedule 8812 (or Form 1040, depending on the tax year). The IRS does not ask for medical documentation of disability when you file; the credit is based on your child's age and your income. However, if the IRS questions whether your child meets the age requirement or your income qualifies, you may need to provide supporting documents.

The Child Tax Credit is partially refundable through the Additional Child Tax Credit, which means some filers receive a refund even if they owe no tax. The refundable portion is limited, so not all of the $2,000 credit may come back to you as a refund, but a portion of it can.

What the IRS means by "disability" for tax purposes

The IRS does not use the same definition of disability as the Social Security Administration or state disability programs. For tax credit purposes, disability generally means a physical or mental impairment that substantially limits one or more major life activities — such as seeing, hearing, walking, working, or self-care — and is expected to last at least 12 months or result in death.

You do not need to be receiving Social Security Disability Insurance (SSDI) or Supplemental Security Income (SSI) to claim a tax credit. You do not need a formal diagnosis from a government agency. What matters is whether the impairment, as documented by a medical provider, meets the IRS standard. This means a person with a chronic condition, a serious mental health condition, a mobility limitation, or a sensory impairment may all may have access to, depending on how substantially the condition limits daily functioning.

If you are unsure whether your condition meets the IRS definition, you can contact the IRS directly at 1-800-829-1040, or work with a tax preparer who has experience with disability-related credits. Some nonprofit organizations that serve people with disabilities also offer free tax preparation and can advise you on whether you may have access to.

How to claim a disability tax credit on your return

You claim disability tax credits when you file your annual federal income tax return. The process depends on which credit you are claiming. For the EITC, you use Schedule EIC. For the Child Tax Credit, you use Schedule 8812 or report it directly on Form 1040, depending on the tax year. Both schedules are available on the IRS website at irs.gov.

You can file your return yourself using tax software, work with a tax preparer, or use free tax preparation services. The IRS Free File program offers free tax software to people who earn below a certain income threshold (usually around $60,000 to $70,000, depending on the year). Many community organizations, libraries, and nonprofits also offer free tax preparation during tax season, and some specialize in helping people with disabilities or low incomes.

When you file, you do not need to submit medical records or proof of disability with your return. However, you should keep documentation on file in case the IRS asks questions later. This might include medical records, letters from your healthcare provider, or documentation from a disability program you are enrolled in.

State disability tax credits and deductions

Many states offer their own tax credits or deductions for people with disabilities, separate from the federal credits. These vary widely by state. Some states offer a disability income exclusion, which allows you to exclude a portion of disability-related income from your state taxable income. Others offer a credit similar to the federal Child Tax Credit but with different income limits or credit amounts.

To find out what your state offers, visit your state's tax authority website — usually called the Department of Revenue or Department of Taxation. You can search for "disability tax credit [your state]" or call the state tax helpline. If you use a tax preparer, they can advise you on state credits as well. Some states require you to file a separate form or schedule to claim a state disability credit, while others allow you to claim it directly on your state return.

What happens if the IRS questions your claim

If you claim a disability tax credit and the IRS has questions, they will contact you by mail. They may ask for documentation of the disability, proof of income, or clarification about your filing status or dependents. This is called an audit or examination. You do not need to respond immediately, and you have the right to representation — you can have a tax preparer, attorney, or enrolled agent respond on your behalf.

If you receive a notice from the IRS, read it carefully to understand what information they are requesting. Respond within the timeframe they give you (usually 30 days). Include copies of supporting documents — do not send originals. If you are unsure how to respond, contact a tax professional or the IRS directly at the number on the notice.

If you disagree with the IRS's decision, you have the right to appeal. The IRS will explain your appeal rights in their notice. You can also contact the Taxpayer Advocate Service, a free IRS program that helps people resolve disputes with the IRS.

Frequently Asked Questions

Do I need to be on Social Security Disability to claim a tax credit?

No. You do not need to receive SSDI or SSI to claim a disability tax credit. The IRS uses its own definition of disability based on whether an impairment substantially limits a major life activity. Many people who do not may have access to for Social Security benefits do may have access to for tax credits, and vice versa.

Can I claim a disability tax credit if I did not work during the year?

It depends on which credit. The EITC requires earned income from work, so you cannot claim it if you did not work. The Child Tax Credit does not require you to work — you can claim it based on your child's age and your income, regardless of whether you are employed. Other credits may have different rules.

What if my income is too high to claim the EITC?

The EITC phases out at specific income levels that vary by filing status and number of dependents. If your income exceeds the limit, you cannot claim the EITC. However, you may still be able to claim the Child Tax Credit or other tax benefits. A tax preparer can review your situation and tell you what credits you may be may have access to to.

Do I have to report my disability to the IRS when I file?

You do not check a box or formally register as disabled with the IRS. You simply claim the credit on the appropriate schedule when you file your return. The IRS does not maintain a registry of people with disabilities. You only need to provide documentation if the IRS asks for it after you file.

Can I claim a tax credit for a family member with a disability who is not my child?

The Child Tax Credit applies only to children under 17. If you support an adult family member with a disability, you may be able to claim them as a dependent on your return, which can affect your tax bill in other ways, but there is no separate disability credit for adult dependents. Consult a tax preparer about your specific situation.
