• Accepted simply means the government received your e-filed tax return. 

• The next step is for the government to approve your refund. It can take anywhere from a few days to 3 weeks to go from acceptance to approval. 

NOTE: Now that you are accepted you can start tracking your federal refund on the IRS Where's My Refund site.
