Filing a tax return after the April 15th deadline typically isn't any different than the normal procedures. Be sure you have all your tax-related documents for income and deductions, prepare your tax returns, and send them into the IRS. Tax software such as TurboTax, H&R Block's At Home and TaxACT are will still be available in desktop and online software through October 15th. The IRS e-file and Free File services also remain operative through October 15th.

The only a couple of extra things to remember about filing after April 15th.

First, remember to include any extension payment along with your other withholdings and payments on your tax return.

Second, if you have a refund, the IRS typically won't assess any late fees -- as long as you file before October 15th. But if you have a balance due, then the IRS will assess a late payment fee along with interest.
