Not yet. Accepted means your tax return is now in the government's hands and has passed the initial inspection (your verification info is correct, dependents haven't already been claimed by someone else, etc.).
Is accepted the same as approved?
Acceptance is what we need and want from each other, but all too often we go around asking for approval instead. And we go around giving out approval (or disapproval) instead of offering acceptance. Acceptance is not the same as approval and approval is not the same as acceptance.
What does it mean when your tax return is approved?
When you receive confirmation that the IRS accepted your return, it means that they have reviewed your return, and it has passed their initial inspection. They verify your personal information and other basic items, like if your dependents have already been claimed by someone else.
