Whether Your Son Must File Taxes on SSDI Payments
Your son does not have to file a federal income tax return based on SSDI payments alone. Social Security Disability Insurance is not counted as taxable income by the IRS, even if he receives a large monthly benefit. However, if your son has other income — wages from work, interest, dividends, or self-employment earnings — he may be required to file a return depending on the total amount.
The key rule is this: SSDI payments themselves are never taxable. But if your son's other income crosses certain thresholds, he must file. For 2024, a single person with no dependents must file if their non-SSDI income exceeds $14,600. If he is blind or over 65, the threshold is higher. The IRS does not care that part of his total income came from SSDI — they only count the other income.
If your son is your dependent and you claim him on your tax return, different rules explore. You may be required to file on his behalf even if his own income is below the filing threshold, depending on your household's total income and filing status. This is a separate calculation from whether he personally must file.
Key Takeaways
- SSDI payments are never taxable income, so your son does not owe federal income tax on the benefit itself.
- If your son has earned income (wages) or unearned income (interest, dividends), he must file a return if that income exceeds $14,600 for 2024, regardless of SSDI.
- If you claim your son as a dependent on your return, you may be required to file on his behalf under different income thresholds than explore to him alone.
- State income tax rules vary — some states do not tax SSDI, but others may tax it under certain circumstances, so check your state's rules.
- Keeping records of your son's SSDI statements (Form SSA-1099) and any other income is necessary to determine filing requirements each year.
When Your Son Has Work Income or Other Earnings
If your son works part-time or has any earned income, the filing requirement changes. The IRS requires him to file if his earned income plus unearned income (interest, dividends, capital gains) exceeds the standard deduction for his age and filing status. For 2024, the standard deduction for a single person under 65 is $14,600. If your son is 65 or older, it is $18,150. If he is blind, add another $1,850.
This matters because many people on SSDI work part-time under the Substantial Gainful Activity (SGA) rules or the Student Earned Income Exclusion. If your son earned $8,000 in wages and receives $1,500 per month in SSDI, he does not file based on SSDI. But if he earned $15,000 in wages, he must file because his earned income alone exceeds $14,600. The SSDI is not counted in that calculation.
If your son has investment income — even a small amount of interest from a savings account — that counts toward the filing threshold too. Add up all non-SSDI income and compare it to the standard deduction for his age. If the total is over the threshold, he must file.
If You Claim Your Son as a Dependent
If your son is your dependent, you have a separate filing obligation. You must file a return on his behalf if his gross income exceeds a threshold that depends on your filing status and whether he has unearned income. For 2024, if your son has only earned income and is your dependent, he must file if his earned income exceeds $14,600. If he has unearned income (interest, dividends), the threshold is lower — $1,300 for unearned income alone, or $14,600 if he has both types.
The reason this matters is that you may be required to file on his behalf even if he would not be required to file for himself. This happens when your household income is high enough that you must file, and your son's income pushes your filing requirement higher. The IRS uses a different calculation for dependents than for independent filers.
If your son is your dependent and you do not file a return when you are required to, you may lose tax credits or deductions that benefit your household. It is worth checking your filing status each year, especially if your son's income changes.
State Income Tax and SSDI
Federal tax rules do not tax SSDI, but state rules vary. Most states follow the federal rule and do not tax SSDI payments. However, a few states tax SSDI under certain circumstances. Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont may tax SSDI depending on your total income and filing status. The rules are different in each state.
If you live in one of these states, you may need to file a state return even if you do not file a federal return. Some states have their own standard deduction or income thresholds that differ from the federal amounts. Check your state's tax agency website or contact them directly to learn whether your son's SSDI is taxable in your state and whether he must file a state return.
If your son has moved to a different state during the year, you may need to file returns in both states. This is rare but possible, especially if he moved mid-year for work or other reasons.
What Documents You Need to Track
Social Security sends a Form SSA-1099 to your son each January if he received SSDI during the previous year. This form shows the total SSDI payments he received. He should keep this form with his tax records, even though SSDI is not taxable. The IRS may ask for it if there is ever a question about his income.
If your son has earned income, his employer will send him a Form W-2 (if he is an employee) or he will need to track income and expenses if he is self-employed. If he has interest or dividends, financial institutions will send Form 1099-INT or Form 1099-DIV. Collect all of these forms by the end of January and add up the totals to determine whether filing is required.
Keep the SSA-1099 even if your son does not file a return. If the IRS ever questions his income or yours, the form proves that part of his income came from a non-taxable source. This can protect him and you from penalties or audits.
How to File If Your Son Must File
If your son must file a return, he can file on his own using free software (IRS Free File), by mail, or with a tax preparer. If he is your dependent, you can file his return separately or include his income information on your own return, depending on your situation and the software you use. Most tax software will ask whether you have dependents and will guide you through reporting their income.
If your son has a representative payee (someone who manages his SSDI benefits on his behalf), that person does not file the tax return for him — your son files it himself, or you file it on his behalf if he cannot. The representative payee's role is to manage the money, not to handle taxes.
If your son's income is very low and he does not meet the filing threshold, he still may want to file to claim the Earned Income Tax Credit (EITC) or other refundable credits. Filing can result in a refund even if he owes no tax. This is a choice, not a requirement, but it can put money back in his pocket.
Frequently Asked Questions
Does SSDI count as income for tax purposes?
No. SSDI is never taxable income for federal tax purposes. However, if your son has other income (wages, interest, dividends), that income is taxable and may trigger a filing requirement. The SSDI itself does not count toward the threshold.
What if my son receives SSI instead of SSDI?
Supplemental Security Income (SSI) is also not taxable. However, SSI has strict income and resource limits, so any other income your son receives may affect his SSI payment amount. If he has earned income, Social Security will reduce his SSI benefit. Consult with Social Security about how work income affects his specific situation.
Can my son file a return to get a refund even if he does not have to file?
Yes. If your son had taxes withheld from wages or is may have access to to the Earned Income Tax Credit, he can file a return to claim a refund even if filing is not required. This is optional but often results in money back.
Who files the return if my son cannot do it himself?
If your son is unable to file due to disability or age, you can file on his behalf as his parent or legal guardian. You will need to sign the return and may need to provide proof of authority. A tax preparer or the IRS can tell you what documentation is needed.
What happens if we do not file when we should?
If a return was required but not filed, the IRS may assess penalties and interest. If your son is owed a refund, he has three years to claim it before the refund is forfeited. If he owes tax, penalties accrue. Filing late is better than not filing at all.
