How long should I keep my yearly folders containing everything I need for my taxes? (paystubs, deductions, receipts etc). I've heard various answers, from 3 years, 5 years, 7 years? What is the max the IRS could ever go back? I have complete folders going back 30 years.
I need to keep my paystubs, as with the kind of work I used to do they are proof that I worked on certain projects (and indeed more than once I've had to submit 30-year-old paystubs as such proof), but other than the paystubs, which I'll keep for non-IRS reasons, how many years back do I need to keep everything else (yearly tax returns, receipts, deductions, investment receipts, everything else tax-related) before I can throw it away? And is there any reason you can think of that I'd want to keep things other than paystubs for longer than that?
