With the start of a new year comes a new income tax filing season. So here are a few key tax dates to plug into your smartphone – or if you prefer old school, pencil them in on that shiny new 2016 calendar.

At some time in your life, it’s a fair bet you’ll get one of those nice “invitations” from the IRS, telling you you’re being audited. And while there are some definite steps you should take, the first rule of thumb comes from our British friends: “Keep Calm and Carry On.”

Well, you made it! You got your income tax return e-filed before the Oct. 15 deadline. But what happens if you got a reject notice instead of an acceptance?

There’s no need to panic, although your time to fix the problem isn’t unlimited. The IRS gives you five days after the deadline to fix any problems and refile. So that means you have until Oct. 20 to resend a rejected return.

You’ll get the news in a plain-looking envelope; your only clue – the IRS logo in the return address. That’s right, you lucky taxpayer, you get to justify your income tax choices to the nice IRS agent.

Whoa there, partner. Take a few deep breaths. Calm down. We'll help you through this.
