The dynamisation of art in the 20th century and its impact on typographie by Michael Mahla As early as the first decades of this century, velocity, machines and films were well-known phenomena. They had a decisive impact on the artists of those days.
The statute of limitations on how far back the IRS can audit (called the Assessment Statute Expiration Date or ASED) varies depending upon the circumstances of the tax return. In most cases the IRS will not go back more than 3 years unless there is something very wrong with the tax return that was filed.
It is not until you actually do file a return that the audit time limit -- three years -- and collection time limit -- ten years -- starts to run. As a practical matter, however, if you haven't heard from the IRS in six years, you don't need to worry too much about taxes owed on a nonfiled return. The IRS usually doesn't go after nonfilers after six years -- unless the IRS begins its investigation before the six years elapsed and you owe a large amount of taxes. After six years, the IRS frequently purges its computer files.
