At the start of 2025, I was working as a sole proprietor, but halfway through the year, I started an LLC and elected to file as an S corp. I have a client that I worked with while I was a sole proprietor, and then I continued to work with them after I made the switch. They sent me one 1099-NEC and attributed all compensation to my company, even though some of it was earned earlier in the year before my company existed. Will it cause any issues with the IRS if I file my taxes with the amount I know to be correct, which is different than the amounts on the 1099?
