How Notice Response Deadlines Work

Every compliance notice from the IRS or state agencies comes with a statutory response window. This is the number of calendar days you have to respond before the agency takes default action — which almost always works against you.

IRS notice deadlines typically range from 21 to 90 days, depending on the severity of the notice. State agency deadlines are often shorter — some states give employers as few as 10 calendar days to respond to unemployment claims.

Missing a deadline does not just mean a penalty — it often means losing your right to contest the action entirely. For example, if you miss the 30-day window on a CP90 notice, you lose your Collection Due Process hearing rights. If you miss a state UI claim response window, the claim is approved and your SUI rate increases.
