Verified answer

Your in-laws do not meet the qualifications under the tax code for claiming you as dependents. First of all, in order to claim someone, you have to provide over 50% of their (monetary) support.

If they EACH had less than $3,650 in gross income for 2009 (excluding only non-taxable Social Security) AND you provided more than half of their total support for ALL of 2009 then yes, you can claim them.

'tro' has not read IRS Pub 501 and is just guessing again. In-laws (your spouse's parents) are in a class of relatives who do NOT need to live in your home at all to be classified as dependents.

In IRS pub 501, page 20, there is a support test worksheet. If their income (including unemployment and ssa benefits) is low enough, fill the form out and see if you qualify.

Who was paying the bills (and with what?) for january to october?

Where were they from January to September? To claim them you'd have to show that you provided over half their support FOR THE YEAR, and that they each had under $3650 gross income for the year, not counting social security. So the answer is probably no.

An in-law can be a qualifying relative and does not have to live in the taxpayer's home for the entire year.

unless they lived with you at least 6 months and you paid more than half of their annual support, I don't see how you could or why they would even let you claim them
