⚠️ READ THIS BEFORE PANICKING:
A transcript sequence is not the same thing as an IRS
determination. Dates, dollar amounts, tax period,
Action Codes and related transactions can change the meaning.
For example, a 570 can indicate an account
hold, but it does not automatically mean an audit.
A 420 can indicate examination activity,
but it does not automatically mean the taxpayer will
ultimately be audited.
