Tax season is underway, and the IRS expects 140 million people will file returns by April 15. The agency has also debuted a new online tool to help taxpayers check the status of any refund they may be entitled to.

President Donald Trump this week offered all federal employees a buyout package in an effort to reduce the size of the government workforce, which could impact IRS staffing at an important period for the agency, though it’s not yet clear how. The IRS did not immediately respond to a request for comment.

Receiving refund

If you file your tax return electronically, the IRS says it should take 21 days or less to receive your refund. If you choose to receive your refund with direct deposit, it should take even less time. If you file a paper return, the refund could take four weeks or more, and if your return requires amendments or corrections, it could take longer.

Checking status

Taxpayers can use the online tool Where’s My Refund? to check the status of their income tax refund within 24 hours of e-filing and generally within four weeks of filing a paper return.

Earned Income Tax Credit (EITC)

To qualify for the EITC, you must have under $11,600 in investment income and earn less than a specific income level from working. If you’re single with no children, your income level must be $18,591 or below. And if you’re married filing jointly with three or more children, you must make $66,819 or below.

Child Tax Credit

If you have a child, you are most likely eligible for the Child Tax Credit. The credit is up to $2,000 per qualifying child.

What’s different

The IRS has expanded a program that allows people to file their taxes directly with the agency for free. The federal Direct File program, which permits taxpayers to calculate and submit their returns without using commercial tax preparation software, is now available to taxpayers in 25 states, up from 12 states that were part of last year’s pilot program.
