How far back can you pay taxes?
Nathan Sanders 
The IRS can go back to any unfiled year and assess a tax deficiency, along with penalties. However, in practice, the IRS rarely goes past the past six years for non-filing enforcement. Also, most delinquent return and SFR enforcement actions are completed within 3 years after the due date of the return.
