Never done a 90 day report before. Im on 12 month based on marriage, and due on 29th this month at Udon. I want to go early b4 amnesty ends. so how early can i go and what do i need to take. Thanks.
TLDR : Answer Summary
You can file your 90-day report in person between 15 days before the due date and 7 days after the due date. Since your report is due on the 29th, you could have filed as early as the 15th of this month.
