IRS Collection Statue Expiration Date (CSED)
“It is a basic concept of law that once a statute of limitation has passed, no action barred by the statute may take place.”
The IRS collections statute expiration date (CSED) is the date after which the IRS can no longer collect a tax debt.
When things are simple, the CSED is easily calculated as 10 years from the date of assessment.
This means that no matter how little the IRS has been able to collect on a tax debt assessed in April of 2007, they must cease collection on that debt in April of 2017.
However, when you’re working with the IRS, things are rarely as simple as you’d like. There are a handful of events that can result in extending the CSED date (sometimes called “tolling events”).
