When are taxes due to the IRS?
HI OPTION # 1: If you owe taxes when you file the IRS would prefer that you send them a check along with form 1040-V (payment voucher) and your return. OPTION # 2 Or if you elect to make monthly payments then you need to file form 9465 (installment agreement request) this form explains the fee that they charge if your request is approved. Bottom line: if you can pay what you owe your better off. If you make payments there will be an interest of 1% charged daily on your unpaid balance.
