The IRS is urging taxpayers to check their mid-year withholdings.

The IRS is now required to hold 2017 income tax refunds for a few weeks for taxpayers who claim the Earned Income Tax Credit and the Additional Child Tax Credit. The IRS will also be reviewing returns more closely due to the threat of identity theft and that will cause a delay in returns and refunds being processed.

If you are accustomed to receiving a large refund early in the spring, you may want to change your withholdings so that you can have more take home money now.

You can read the full notice from the IRS here.

Form W4 is used to adjust withholdings.
