Your not really clear on what your saying.
The amount of deductions (they aren't done by specific person) you use for withholding purposes does not effect what you can or may claim on the return for the period. The correct amount must be used on the return, and the specific SS# and reason established. Any over or under paid tax, after all types of income (some may not even had withholding) and deductions are determined is what you pay or get refunded.
You should report having a dependant in the home.
Depends on the tax rules that apply to the country you are claiming in.
no, once you claim someone you cannot be claimed yourself
no
If they aren't a qualified child or a qualified relative, as defined, you can't claim them.
Yes, you can generally claim someone on your taxes if they have been in jail, as long as they meet the qualifying criteria for being a dependent. The IRS does not restrict claiming someone simply because they have been in jail. However, there are specific criteria that must be met, such as living with you for more than half the year and not providing more than half of their own support.
Of course, they must be a "qualified relative" before you can even hope to claim them. It depends on your specific tax situation, but each dependent is worth +/- $750 of additional refund.
No you do not have to file unless someone is claiming you as a dependent. Then file jointly with them.
A large fine.An audit also.
they get taxed more and if they don't pay that then they get sewed
Unless you are providing more than half of a person's support, you can not claim them on your taxes. If a person is surviving on public assistance, and supporting themselves from that they can not be claimed on taxes.
If you have paid for more than half of their support and they do not claim themselves on their taxes, I believe you can claim them as long as you have documentation to prove it.
