Yeah. We got a notice a few months ago telling us that some of the income we had received in our work was WAAAAY under-reported. Fortunately, we had kept our originals in a tax file; copied them and sent them back. It was resolved in our favor, but had we not kept originals or if they’d been lost or burned up - we’d be liable for the boo boo their errors had caused.
They wanted me to sign off on about $14K in taxes, interest, and penalties.
