With the approaching 1040 deadline, we and agencies are experiencing extremely high e-filing volume. You may experience longer wait times for acknowledgements (ACKs) from the Electronic Filing Center (EFC), the IRS, and states.
We recommend that you transmit e-files early (don't wait until the deadline) and often (not in large batches) during this period, as ACKs may take longer to post.
We appreciate your patience.
