My first instinct was no! As emotionally cathartic as it would be - there must be some reason to hold onto those documents? And the answer - in this case - is probably not. In terms of the IRS, there are three basic statutes of limitations:
- Three years - The IRS can contest any return they like for any reason 3 years after it has been filed (basically)
- Six years - The IRS has a number of exceptions to the three year rule where they can still contest your return
- Unlimited - If you have intentionally filed a fraudulent and they can prove that, there is no statute of limitations.
Any documentation relating to "basis", or what you paid for an asset should be kept for the life of the asset. The IRS always assumes basis is $0.00 - the burden is on the taxpayer to prove what they paid. So, if next year she sold some equipment related to that business for $1,000 - the IRS will assume a gain of $1,000 unless she could prove otherwise.
I don't have my official blog disclaimer - yet - but you know you can't take tax advice from a blog on the internet into tax court, right?
