1. Get your tax forms online

Never got your W-2 in the mail? Don't panic, because many employers maintain employees' W-2 online. Check with your HR department to find out if yours is posted on a third-party site like MyTaxForm, Tax Form Management or Rapid Tax. 

If you can't get your hands on your W-2, file anyway on time, according to GoBankingRates.com. Use form 4852, which is the substitute for the W-2 and just estimate your wages to the best of your ability. If you are anticipating a refund, expect a delay as the IRS will have to verify the information before releasing your refund.

You can also log onto your bank and online investment accounts for any 1099 forms you might need to report interest and capital gains. Many tax programs will even automatically import the forms into their software so you never have to hand type in the numbers. Just be careful that nothing got mixed up during the process, since any errors are on you.​

2. Look for easy credits and deductions

Whether you do your taxes yourself or hire a pro, be sure not to miss obvious deductions. 

Start with your IRA, which you can contribute to all the way up until tax day. An IRA contribution will lower your taxable income, which means you'll owe less money in taxes to Uncle Sam. (Don't have an IRA yet? Here's how to open one.) 

If you make less than $30,750 (or $61,500 if married and filing jointly), you can also get a tax credit  — known as the saver's credit  — on an IRA contribution of up to $2,000, which will save you even more money.

Don't forget to indicate that the contribution is for 2016 — an easy error to make if you are in a rush. You can contribute up to $5,500 annually to your IRA if you are under age 50.

4. Consider getting an extension

If you really don't think you can make it work, you have until October 16 to get your federal tax forms turned in if you request an automatic extension using this IRS form or tax software like TurboTax Easy Extension. 

The good news is there's no fee to file

3. Consider getting an extension

If you really don't think you can make it work, you have until October 16 to get your federal tax forms turned in if you request an automatic extension using this IRS form or tax software like TurboTax Easy Extension. 

The good news is there's no fee to file for an extension and — here's a myth-buster — filing for an extension doesn't mean you will be audited either, according to Forbes. All you'll need is your social security number, an estimate of your 2016 tax liability, the total amount you paid in 2016 — which includes withholding and estimated payments along with the total amount you are paying with your extension request.

4. Pay what you owe (if you owe)

You read that right — just because you file late, doesn't mean you get to pay late. Instead, it means you need to estimate what you owe and send the IRS a check.

Be careful not to underestimate. "If you are $1,000 off from what you owe, you will be charged interest on the additional amount you owe until you pay," Brian Ashcraft, director of compliance at Liberty Tax Service, told Mic by phone. The interest rate is the federal short-term rate, plus 3%, according to the IRS, which is calculated every three months.

Those who can't pay what they owe to the IRS can workout a payment-plan agreement instead. As with any loan, you make monthly payments, but keep in mind that interest and fees apply.
