I forgot to get a tax permit before selling—what do I do after the fact?
The best move is to register quickly and proactively report your sales.
The Narrative
The Empathy
You made sales without a permit and now feel anxious about penalties. You want to fix it without making things worse.
The Education
Tax agencies typically prefer voluntary compliance. If you register quickly and report what you collected (or should have collected), you can often resolve the issue with minimal penalties. The longer you wait, the more complicated it can become. Keeping clear records of those sales will help you file accurately.
The Solution
Apply for the permit as soon as possible, then contact the tax authority or use their portal to file for the period in question. If you did not collect tax, you may need to pay it out of pocket. Save your records and keep future sales tax separate so you stay on track going forward.
