How do I get W2 info for previous years (before 2005)?

Question

I just filed my 2006 and 2005 Illinois Tax returns. I've done my federal tax returns every year, but this is my first time doing my state taxes. I want to file as far back as possible (I never realized I'd be getting money back!), but I can't find my old W2's or completed copies of my federal tax returns before 2005. Also, does anybody know how many years I can go back on an Illinois Tax return? I also heard that I could get interest on refunds from state tax returns that I didn't previously file. Is this true, and if so how much interest would I get? Thanks, for any help anyone gives. Matthew 7:12

Answer 1

You will either need to contact the IRS or your previous employer and ask for the W2 for that time period. Your best bet is probably going to be the IRS.

Answer 2

Employers are required by law to keep payroll records until hell freezes over. Contact pre-05 employers and ask for a copy of your W-2 for year whichever. Usually you get interest if the state has messed up somehow and delayed your refund. If the fault is yours I wouldn't bet on interest; instead they will charge you interest for being late, late, late. If you are due a refund they had the use of your money and won't charge you interest. You usually have to file returns back for as many years as there are that you didn't file a return. Good luck.
