WASHINGTON
With the April 18 deadline fast approaching, the Internal Revenue Service today offered taxpayers still working on their 2016 taxes a number of tips. These tips are designed to help taxpayers avoid common errors that could delay their refunds or cause other tax problems in the future.

The IRS encourages taxpayers to file electronically. Doing so, whether through e-file or IRS Free File, vastly reduces tax return errors, as the tax software does the calculations, flags common errors and prompts taxpayers for missing information. And best of all, there is a free option for everyone. Whether filing electronically or on paper, be sure to keep a copy of your tax return.

In addition, the IRS offers these last-minute tips:

Refunds

The best and fastest way for taxpayers to get their refund is to have it electronically deposited into their bank or other financial account. Taxpayers can use direct deposit to deposit their refund into one, two or even three accounts. See Form 8888, Allocation of Refund, for details.

Make sure the financial institution routing and account numbers entered on the return are accurate. Incorrect numbers can cause a refund to be delayed or deposited into the wrong account. After filing, whether or not direct deposit was chosen, use “Where’s My Refund?” on IRS.gov or download the IRS2Go Mobile App to track the status of a refund.

The IRS issues nine out of 10 refunds in less than 21 days. “Where’s My Refund?” provides the most up-to-date information. The tool is updated once per day, usually overnight, so checking more often will not generate new information. Calling the IRS will not yield different results from those available online, nor will ordering a tax transcript.

Special Instructions for Paper Filers

Math errors and other mistakes are common on paper returns, especially those prepared or filed in haste at the last minute. These tips may help those choosing this option:

• Fill in all requested Taxpayer Identification Numbers, usually Social Security numbers, including all dependents claimed. Check only one filing status and the appropriate exemption boxes.

• When using the tax tables, be sure to use the correct row and column for the filing status claimed and taxable income amount shown.

• Sign and date the return. If filing a joint return, both spouses must sign.

•Attach all required forms and schedules, such as Schedule A for people who itemize their deductions. In addition, attach to the front of the return all Forms W-2 and other forms reflecting withholding.

• Mail the return to the right address. Check Where to File on IRS.gov or the last page of the tax instructions. If mailing on Tuesday, April 18, be sure to do so early enough to meet the scheduled pick-up time and ensure a postmark before the midnight deadline.
