Even though the IRS issues 9 out of 10 tax refunds within 21 days, it's possible your return may require additional review and take longer to process.

For some taxpayers, PATH Act requirements and other identity-protection safeguards implemented by the IRS may account for longer wait times. (Earned Income Tax Credit (EIC) and/or Additional Child Tax Credit)

Other things that can delay your refund include but are not limited to:

• Liens, back taxes, or refund offsets;
• Errors, inconsistencies, or missing information;
• Identity fraud;
• Form 8379, Injured Spouse Allocation, which can take 11-14 weeks to process.

Also, if you chose direct deposit, your financial institution may need another day or two to post the refund to your account, so keep that in mind.

If it has been more than 21 days since your return was  accepted , you can  call the IRS directly  to check on your refund status.
