Yes, a parent can be your dependent. Your mother does not have to live with you, but for 2026 her gross income (not counting tax-exempt Social Security) must be under $5,300 and you must pay more than half of her total support. At a household income of $750,000 or more, though, the dependent label itself is worth almost nothing. What matters is how her care costs, your benefits and any gifts are handled.
This guide covers the four IRS tests, why the dependent credits disappear at your income, and the three places where supporting a parent can still change your tax bill in California or Washington.
The four tests a parent must pass to be your dependent
A parent can only be a “qualifying relative,” never a qualifying child. IRS Publication 501 lists four tests, and all four must be met:
- Not a qualifying child test. She cannot be anyone’s qualifying child. For a parent this is almost always met.
- Relationship test. A mother, father, stepparent or grandparent qualifies by relationship alone. She does not need to live with you. A parent-in-law also qualifies.
- Gross income test. Her gross income for 2026 must be less than $5,300 (Rev. Proc. 2025-32, section 4.23). Gross income means income that is not exempt from tax: pensions, IRA withdrawals, rental receipts, interest and the taxable part of Social Security. Tax-exempt Social Security does not count toward this test.
- Support test. You must provide more than half of her total support for the year. Total support includes the fair rental value of her housing, food, medical care and anything she pays for herself from her own income or savings, including tax-exempt Social Security.
She must also be a U.S. citizen, U.S. national or resident of the U.S., Canada or Mexico, and she generally cannot file a joint return with a spouse (except to claim a refund).
The test that usually fails is gross income. A modest pension or a required IRA distribution can push a parent over $5,300 on its own.
What claiming her is worth at a $750k to $3M income
Very little, directly. The federal credit for other dependents is $500 per qualifying relative (Schedule 8812). It shares the phase-out with the Child Tax Credit: the combined credit drops by $50 for every $1,000 of modified AGI over $400,000 for joint filers. A family with two children under 17 and a dependent parent has $4,900 of possible credits ($2,200 x 2 + $500). That is gone by $498,000 of MAGI.
California works the same way. The 2025 dependent exemption credit is $475 per dependent (Form 540), and it shrinks by $6 for every $2,500 of federal AGI over $504,411 for joint filers (FTB 540 booklet, line 32). At $900,000 of AGI the reduction is $954 per dependent, more than the credit itself. California’s separate Credit for Dependent Parent is only available to married people filing separately whose spouse lived elsewhere for the last six months of the year, so it rarely applies.
Washington has no individual income tax in 2026, so there is no state dependent benefit to chase. Note that Washington has enacted a 9.9% tax on individuals and joint filers with AGI over $1,000,000 starting January 1, 2028 (WA DOR); the detailed rules are still pending.
So for this reader the real question is not “can I claim Mom?” It is “how should we pay for Mom’s care?”
Where supporting a parent still moves your tax bill
1. Her medical and long-term care costs
You can deduct medical expenses you pay for a parent who is your qualifying relative, and Publication 502 drops the gross income test for this purpose. If you provide more than half her support, her medical bills can count on your Schedule A even if her pension is far above $5,300. The catch is the floor: only medical costs above 7.5% of your AGI are deductible, and only if you itemize.
Assisted living and memory care count when a principal reason she is there is to get medical care, or when the services are qualified long-term care services for a chronically ill person under a plan of care prescribed by a licensed health care practitioner. For the second route, a licensed health care practitioner must have certified her as chronically ill within the previous 12 months, so families typically keep that letter on file each year.
2. Your dependent care FSA
A parent who cannot dress, feed or care for herself and lives with you for more than half the year can be a qualifying person for dependent care benefits (Publication 503). Again, her income does not disqualify her. But the 2026 dependent care FSA limit is $7,500 per household, not per person (P.L. 119-21, section 70404). If your children’s preschool or after-school care already uses the full amount, your mother’s care adds no room. The same dollar of care also cannot be used for both the FSA and the medical deduction.
3. How you pay matters for gift tax
Money you give your mother to spend counts toward the 2026 gift tax annual exclusion of $19,000 per recipient per donor ($38,000 for a married couple who split gifts). Payments made directly to a doctor, hospital, care facility or insurer for her medical care are excluded from gift tax with no dollar limit (Form 709 instructions, “Medical exclusion”). Paying the memory care facility directly, rather than sending her a monthly transfer, can keep those dollars out of your gift tax reporting, but only the part that counts as medical care under the income tax definition. Any part of the payment that is not medical care is still a gift to her. Gifts above the annual exclusion rarely create tax (the lifetime exclusion is $15,000,000 per person for 2026), but they do require filing Form 709.
Worked example: a $900,000 Bay Area household supporting a mother
Assumptions: married filing jointly in California, $900,000 of W-2 and RSU income (AGI), two children ages 4 and 7. The family already itemizes. Priya’s mother, 76, has a $9,000 taxable pension and $22,000 of Social Security, and spends all of it on herself. The family pays $5,000 of its own unreimbursed medical costs and has $40,000 of other itemized deductions (including the $10,000 SALT cap that applies at this income for 2026). We assume she is certified as chronically ill and all of the care below qualifies as medical care. Tax year 2026.
Her $9,000 pension fails the $5,300 gross income test, so she is not their dependent. That costs them nothing, because the $500 credit would have phased out anyway. The medical deduction can still work if the family pays more than half of her total support, which is clearly the case in Scenario B ($132,000 from the family against the $31,000 she spends herself).
| Scenario A: in-home aide | Scenario B: memory care | |
|---|---|---|
| Care paid by the family | $48,000 | $132,000 |
| Family’s own medical costs | $5,000 | $5,000 |
| Total medical expenses | $53,000 | $137,000 |
| Floor: 7.5% x $900,000 AGI | $67,500 | $67,500 |
| Deductible amount | $0 | $69,500 |
| Approximate federal value (35 cents per dollar) | $0 | About $24,300 |
Why 35 cents and not 37: from 2026, households in the 37% bracket have itemized deductions reduced by 2/37 (P.L. 119-21, section 70111), so each deducted dollar saves about 35 cents federally. With the assumptions above, the family’s taxable income stays in the 37% bracket after the deduction, which is what makes the 35-cent figure hold. California itemized deductions follow California law and are figured separately.
The lesson: below roughly $67,500 of combined medical spending, the deduction does nothing at this income. Full-time facility care is where it starts to matter, and that is often the same year the family is least able to think about receipts.
When siblings share the cost
If you and your siblings together pay more than half of your mother’s support but no one pays more than half alone, one of you can still treat her as a qualifying relative under a multiple support agreement. Each person counted must provide more than 10%, the others sign a statement agreeing not to claim her, and the claiming sibling attaches Form 2120 (Publication 501, “Multiple Support Agreement”). The claiming sibling can count only the medical costs they actually paid themselves; the other siblings cannot deduct any of them. Families usually pick the sibling who benefits most, often the one with the lower AGI, whose 7.5% floor is lower and whose credits have not phased out.
Common mistakes with a dependent parent
- Forgetting that a required IRA distribution or small pension counts as gross income.
- Leaving out her own Social Security when adding up total support, which makes your share look larger than it is.
- Assuming she must live with you. A parent can live in her own home or a facility and still qualify.
- Paying her care through transfers to her account instead of directly to the provider.
- Counting the same care cost in both the dependent care FSA and the medical deduction.
What to write down for your family
Caring for a parent is one of the clearest money decisions your children will watch you make. Write a short Decision Memo: who in the family pays for what, why you chose facility care or home care, how you split it with siblings, and where the receipts and physician letters are kept. Keep it in your FamilyKnowledge® Library next to your own estate documents. Conversations fade. Documentation compounds. One day your children may be making the same decision about you.
Frequently asked questions
Can I claim my mother as a dependent if she lives in her own home?
Yes. A parent meets the relationship test without living with you. She still has to pass the gross income test (under $5,300 of taxable income for 2026) and you must pay more than half of her total support, which includes the fair rental value of the home she lives in. The dependent care FSA is different: it requires her to live with you for more than half the year.
Does my mother’s Social Security count toward the $5,300 limit?
Only the taxable part. If Social Security is her only income, it is usually not taxable and does not count. It does count as money she spent on her own support, which matters for the support test. Pensions, IRA withdrawals and interest all count toward the gross income limit.
Can a disabled adult parent be claimed as a dependent?
The same four tests apply. Disability does not change the gross income limit for a parent. What it changes is the dependent care FSA: if she cannot care for herself and lives with you for more than half the year, her care can qualify even when her income is too high for her to be your dependent.
Next step
Before the next open enrollment, check whether your dependent care FSA is already used up by the children, and start a folder for your parent’s care receipts and physician letters. If a parent’s care is becoming a five-figure annual cost, our tax management and estate planning work at the Age Five Family Office™ can help you decide how to structure the payments.
