- 90 days
- How urgent
- Emergency. Act this week

- Yes, with a deadline
How long you have
This notice gives you 90 days to respond. The due date is printed on the letter itself.
The IRS's own guidance on any notice is short: “If we ask you to respond, act by the due date.”
What we do with a Letter 531
Everything the 90-day letter demands, we handle: petition, Appeals settlement talks, or the resolution track that fits the numbers.
This page is general information, not advice on your specific matter. An Enrolled Agent has to read your actual notice and your transcripts before telling you what to do about it.
