The tax season is officially open. Monday, Jan. 27 is the first day you can file your returns. They may not be due until April 15, but getting a head start will get you a quicker refund. Or give you more time to save if you owe the Internal Revenue Service (IRS) some cash.

“The IRS expects more than 140 million individual tax returns for tax year 2024 to be filed ahead of the Tuesday, April 15 federal deadline,” reads the release. “More than half of all tax returns are expected to be filed this year with the help of a tax professional, and the IRS urges people to use a treated tax pro to avoid potential scams.”

Here's a look at key dates in the tax filing season, including deadlines to file, when to request extensions and how long until you get your refund.
