What is the last day you can pay income taxes?

Answer 1

Taxes MUST be paid throughout the year, in estimates as to what will be due.. This is done by either withholding from paychecks or from quarterly estimated payments, generally made by the self employed and others without an employee paycheck. Tax returns are filed by April 15th of the following year and any additional tax owed above the estimate is paid at that time. (Refunds will be sent following the filing too). If the estimates are below certain thresholds (underpaid), then penalties and interest are due too. An extension of time to file the return, BUT NOT TO PAY THE TAX, is easily obtained. OF COURSE YOU CAN (or must) PAY THE TAX AT ANYTIME AFTER THAT TOO. Not paying it does NOT make it go away. The longer it goes not paid, the more the penalty and interest that may also be due.
