If you are selected for audit and have taken a deduction, the auditor is going to ask to see a receipt. And if you have a receipt that you’ve gotten from a cash register that prints on thermal paper, you might now have a blank receipt.
And over time and exposure to light, thermal receipts fade.
You can bring them back to life with an iron or hair dryer. You end up with a reverse image, but at least it’s readable for awhile.
Looks like we’re in for an onslaught on IRS and state audits. The government’s broke and the budgets across the board are funneling money into the division that puts money in the coffers – the audit division. Make sure you have good records!
