The clock is ticking: there are less than two weeks until Tax Day.

If you haven't filed your return yet, you're not alone.

The Internal Revenue Service reported that it received nearly 81 million returns as of March 24. In total, the IRS said more than 168 million individual tax returns are expected to be filed this year "with the vast majority of those coming before the April 18 tax deadline."

If your return contains no errors or red flags, your refund should be delivered within 21 days if you file electronically and opt to have the money directly deposited in your bank account, the IRS said.

But if you're scrambling to finish your tax return by April 18, you should file an extension immediately before it's too late.

How to file an extension: If you can't make the April 18 tax deadline, file an extension now. Here's what to know.
