, using tax information the IRS already has,
I had a carpenter that before this had revenues close to $100,000. After this we only got 1099’s showing he made $50,000 as the home owners never filed the 1099.
He filed his tax return based on what the government knew.
I’d think that could come back to bite him if one of his clients sells a home and claims the improvement to adjust the value of the home (to reduce the gain on sale); if the client can prove to the IRS that he paid the carpenter, the IRS may look into the payment (and open a can of worms).
