I owe money back for taxes. I dont have the money to pay now or the Turbo Tax fee. What happens if file one week late?

IRS will send you a bill for seven days of interest.

to avoid other fees, go to  IRS.gov make-a-payment page and pay $5.00

select reason for payment: EXTENSION.

final amount you owe will be five dollars less.
