Terms of use

The pages here are general information about IRS letters, based on the irs.gov pages they link. They are not tax, legal or accounting advice for your case. Check any rule against the linked irs.gov page before you act.

The letter reader and the counters are automated tools and can be wrong. The date printed on your notice controls, so never let a tool make you miss it.

When you call or send the form, you talk with an independent licensed tax professional, who is responsible for the advice they give. Do not send someone else's details without their permission.

These terms come from IRS Notice Code, 55 E 11th St #1OTH, New York, NY 10003. We may change them; the date below shows the last change.
