Q. 34K check from joint account, need to file Form 709?
A. No. That is each of you making a $17K gift, which is the limit.
Q. If i need to file, does TurboTax support Form 709?
A. No.
Q. If not, can I submit Form 709 separately?
A. You must file form 709 separately. It is not part of your income tax filing.
"Gift Tax" is somewhat of a misnomer. Even though a gift tax return may be required, very few people ever actually pay federal gift tax. The purpose of the gift tax return is usually only to document a reduction in the allowable estate tax exemption.
