Worksheets are generated monthly and approved between the 5th and the 10th. For monthly returns, the worksheet will be approved monthly. Quarterly returns’ worksheets will stay in a pending approval state until the quarter expires.

Once the worksheet approval occurs, the filing calander cannot be edited or adjusted. For more information about filing calendar actions, take a look at your options for unlocking approved returns
