How long do i have to wait? I filed my 2020 taxes in Jan. it was accepted 24hrs later and I still have not received my refund. Anyone else have this issue?

Yes. A lot of taxpayers are in the same situation as you due to the IRS backlog right now. Although The IRS issues most refunds from e-filed returns in about 21 days, some returns take more time to review. In addition, the IRS is processing millions of returns, as well as stimulus checks, and they are doing everything they can to be as prompt as possible. 

Since your return has been accepted, you can begin to track your refund at the IRS Where's My Refund? site. You'll need your Social Security number or ITIN, filing status, and the exact amount of your refund to check your status.

For some taxpayers, PATH Act requirements and other identity-protection safeguards implemented by the IRS may account for longer wait times.

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.

It could not have been Accepted in January, as the IRS did not start to do so until February 12, so please check that first.

That being said, the IRS is seriously backlogged due to all the new tax laws and extra stimulus filings, as well as unprocessed 2019 returns left over from the COVID shutdown.  Lots of other folks are still waiting, so please continue to be patient.  Also see:
