Not sure why you'd need your 2006 tax form? Here are a few reasons:

• Buying a car? Unless you pay cash, you'll be borrowing money - and if you borrow money, you'll need to prove that you can earn enough to pay it back.
  And your 2006 tax forms can do that for you!
• Renting an apartment? 2006 tax forms will show that you can earn enough to pay the rent.
  
• Just need some extra cash? Your 2006 tax forms could be a gold mine! The IRS reports that over 17% of paper tax returns have errors - if yours is one of them, you could have overpaid your taxes by hundreds of dollars (but you'll have to act fast, or the IRS might not be willing to pay up).
  

So you're ready to get 2006 tax form - what's the next step? First, you need to figure out your situation: did you file taxes after 2006? If you did, you're fine; if you didn't, asking for the old return could trigger some questions from the IRS.

However, it's best to work with a company that specializes in helping people get their 2006 tax forms, so you'll get the most out of the process.
