Check whether you qualify for the Schedule R credit and see the exact dollar amount before the income phase-out wipes it out.
| Scenario | Credit | Reduced Base | Starting Base |
|---|---|---|---|
| Single, 68, $5,000 AGI | $375 | $5,000 | $5,000 |
| Single, 68, $12,000 AGI | $75 | $500 | $5,000 |
| Single, 70, $8,000 AGI, $2,000 SS not taxed | $375 | $2,500 | $5,000 |
| Married, both 65+, $12,000 AGI | $563 | $5,500 | $7,500 |
| Single, 68, $16,000 AGI (phased out) | $0 | $0 | $5,000 |
Schedule R works down from a base amount: you start with $5,000 (single) or $7,500 (joint, both 65+), subtract income above the $7,500 / $10,000 threshold, subtract nontaxable Social Security, then take 15% of whatever is left — never more than the cap. Every row above comes from the same code this page runs.
| Filing status | Base | Threshold | Maximum credit |
|---|---|---|---|
| Single | $5,000 | $7,500 | $375 |
| Head of household | $5,000 | $7,500 | $375 |
| Married filing jointly (both 65+) | $7,500 | $10,000 | $562.50 |
The credit is non-refundable: it reduces tax owed but generates no refund by itself. Because you need income above $7,500 (single) before any phase-out begins but exceed roughly $17,500 before the credit disappears entirely, the window of usefulness is narrow — which is exactly why so many eligible seniors miss it.
The credit for the elderly or the disabled — Schedule R, attached to Form 1040 — is one of the smallest and least-claimed credits in the tax code, precisely because its income phase-out is so low. Yet for a retiree living on Social Security plus a small pension, it can be worth up to $375 (single) or $562.50 (couple), and it is easy to miss because most tax software only offers it if you answer the age and disability questions.
It is a non-refundable credit, so it only helps if you owe tax after the standard deduction. The computation runs the opposite way from most credits: you begin with a base amount and subtract, rather than starting from income. Single filers rarely benefit once AGI tops about $17,500; joint filers lose the credit entirely above roughly $25,000 with both spouses 65+. That makes it a targeted credit for lower-income seniors and for people under 65 who retired on permanent and total disability.
A single retiree with $12,000 of AGI and $2,000 of tax-free Social Security has a reduced base of $2,500 and a credit of about $375 — right at the cap. Compare that to a couple both over 65 with the same $12,000 AGI: their base is $7,500 with a $10,000 threshold, giving a reduced base of $5,500 and a credit of $562.50. The credit is claimed by perhaps 1% of filers, and the IRS does not flag it, so it is frequently left unclaimed on self-prepared returns.
⚠️ Important: The credit for the elderly or disabled is non-refundable and applies only to certain low-income taxpayers. This estimate uses the 2025 Schedule R base amounts, thresholds and 15% rate. Confirm eligibility and your exact figure with the IRS Schedule R instructions or a tax professional.
