The IRS says electronic filing has forever changed the way Americans file their taxes. The IRS says they broke their goal of two million filers using E-file this year.
At the Wausau Post Office, people who were mailing their paper returns said they wanted until today's deadline because they were paying Uncle Sam.
H & R Block's Bob Smith says it's best to get your returns in today, even if you can't afford to pay the full amount of tax owed. Extensions are available until Aug. 15 but that only gives you more time to get your documents together, you still need to estimate what you owe and pay as much as possible.
Smith says you should double check your math, remember to sign your return and if your return has more than five sheets of paper inside, it may require extra postage. The tax deadline is midnight.
