The Parent Is Not a Dependent Until the Tests Pass: Check Support, Income, and the Other Sibling Before You Claim

Claiming a parent on the family return can lower the tax bill, or it can draw a notice a year later if the parent did not qualify. The question is not whether you pay a lot for your mother. The IRS applies a set of tests one at a time, and one failed line decides the answer.

Local option: New Plan Care gives families in the St. Louis area in-home help so a parent can stay home: companionship, help with bathing and dressing, meals, and overnight care. Call (314) 405-0887.

Start with the relationship and the income line

A parent is a qualifying relative, not a qualifying child. A parent does not have to live in your home to qualify, which is different from most other relatives. The parent's gross income for the year must stay below the threshold the IRS sets for each year. That threshold is indexed and changes, so take the current figure from IRS Publication 501 rather than from a website or an older return.

For this test, gross income means taxable income the parent receives. Social Security counts only to the extent it is taxable. Get the annual benefit statement from SSA, find the taxable part, and bring that number to the preparer. Do not assume the whole check counts, and do not assume none of it does.

Count the support, including the parent's own money

The support test compares what you paid for the parent against everything spent on the parent for the year. Housing, food, utilities, medical costs, and care costs all go into that total. The parent's own money counts too, even if you never touched it. If the parent's benefit checks pay the facility or an in-home worker, the parent provided more than you did, and the support test can fail.

Build the list before you add anything up. For each month, write the amount, the payee, and the account it came from. A ledger like that is what turns a guess into a figure a preparer can check.

Settle the sibling question before anyone claims

If another sibling also pays part of the parent's support, the family may need a multiple support agreement, which is filed on IRS Form 2120. Only one person can claim the parent in a given year. Ask each sibling in writing which year they plan to claim and what each has paid. A claim made without that conversation is the kind that comes back as a notice.

What to bring to the preparer

• The parent's gross income by source for the year, with the taxable part of Social Security marked.
• The monthly ledger of every payment for the parent's housing, food, medical, and care costs, with the account each came from.
• Each sibling's support amounts and the years each plans to claim.
• Receipts for the medical costs you paid, not estimates.

Medical costs you paid for a parent can sometimes count toward your own medical deduction even when you cannot claim the parent as a dependent. IRS Publication 502 explains when that applies, so check its rules against your own payments before you decide how to file.

These are the order of the tests, not a ruling on your return. The preparer and the IRS publications decide what gets filed. For the public sources behind this page, see the Sources page.
