Hi, I'm a little confused with "claiming the fact that I work from home 3 days a week" on their taxes.
One, they would have to be paying more than 50% of yours and your son's support, which sounds like it is not possible.
Two, if you are not aware what their income situation is, you may not even know whether they have any taxable income to report in the first place and not have any tax liability.
There is no benefit in them trying to claim you and or your son, as they would need to know your SSN and dates of birth to make that attempt, which may not be justified.
