Did the tax rule change this year for claiming an elderly parent? She made social security last year but this year the from indicates she is not allowed more $5,000.?

You do not count her Social Security.   The $5050 limit is for OTHER kinds of income like pensions, investment income, working part-time, etc etc. etc.

Qualifying relative

• They don't have to be related to you (despite the name).
• They aren't claimed as a dependent by someone else.
• They're a U.S. citizen, resident alien, national, or a Canadian or Mexican resident.
• They aren’t filing a joint return with their spouse.
• They lived with you the entire year (exceptions apply).
• They made less than $5050 in 2024.   (Not counting Social Security)

When you add someone as a dependent, we'll ask a series of questions to make sure you can claim them. There may be other tax benefits you can get when you claim a dependent.
