Taxes are due today, April 15.  If you need more time to pay, you can request an instalment agreement.

If you haven't filed yet:

1. Go to File
2. On the How do you want to pay your federal taxes? screen, select Request an IRS payment plan

If you have already filed, you can apply for a payment plan (Form 9465) at the IRS Payment Plans and Installment Agreements website. 

The initial date is of course April 15th, but you can ask for an extension to give you some extra time, which is generally three to six months. You can ask for another extension, but you will need to explain the reason for the delay. They will work with you, but you can't put them off forever.
