Question: how long do you have to pay your federal taxes owed?
Answer: Consider an installment plan. This is a good option if you need more than 120 days to pay your tax bill and you owe less than $50,000. When you file your tax return, fill out IRS Form 9465, Installment Agreement Request (PDF). The IRS will then set up a payment plan for you, which can last as long as six years.
