How long does it take the IRS to receive my return once I E-File?

What does "Pending" mean? 

Pending simply means that your e-filed return is on its way and that the government hasn't accepted or rejected it yet.

If you e-filed your return in January, it'll stay in Pending status until the IRS starts processing the backlog of returns.  The official start date for processing is 1/27/20 however some early filed returns MAY be pulled in one of the testing batches. 

After January, e-filed returns generally sit in Pending status for 24–48 hours before coming back as either Accepted or Rejected. Sometimes state returns stay in Pending for several days or even longer.

Keep calm and check back

Until your state or the IRS processes your return,  you may hear there's "no record found." That actually means the return's still being processed. Just check back in a few days.

Usually within 24 to 48 hours after filing.  But since you e-filed before the IRS is officially open to receive tax returns on January 27, it may be several days after opening.
