It's April 15th. If you know there's no way in h-e-double hockey sticks that you're going to make it getting your taxes done and filed online or by snail mail by midnight; here's the link of the day.
Don't forget to do the same for state taxes. There are still residents of two states who don't have to worry about that part; Texas and Florida.
One last tip: the prevailing belief is that those that file online are less likely to get audited.
Good luck. Don't forget to write off those iPhones as a business expense (assuming you use yours for business and you're not reimbursed by your employer).
