Where AI form filling goes wrong on Form 1099-C

Form 1099-C has only a few boxes, but a canceled-debt file holds many dates, many dollar amounts and several codes, and only one of each belongs on the form. These are the common places AI tools and autofill get it wrong. What the form requires is for the IRS to say. Follow its instructions. IRS instructions for Form 1099-C.

The balance, the payment or the discharged amount

A canceled-debt file is full of dollar amounts: the original loan, the unpaid balance, the payoff, the sale proceeds, what the borrower paid. Software can copy any of them into box 2.

Which date is the identifiable event

The file carries a charge-off date, an approval letter, a closing date, two signature dates and the date the report was prepared. Software often takes the first date it sees, or the date on the letter.

Interest in the total, or interest on the account

Box 3 is only for interest included in the discharged amount, as the form says. Payoff statements also show interest paid this year, a daily interest charge and a rate, and software can copy one of those.

The event code letter, not a status code

Box 6 takes one letter for the kind of event. Collection notices and loan systems carry their own status and workflow codes, and software can copy one of those, or the whole explanation.

Which value is the fair market value

A short sale file has a listing price, a sale price, an assessed value and an appraised value. Software can put any of them in box 7.

The sold property isn’t the debtor’s address

The loan, the notices and the appraisal all show the property’s address, and the borrower has since moved. Software can fill the old address as the debtor’s.

How Fyllyo takes care of them

With a test client and seven documents (the lender’s reporting authorization, a deficiency waiver, a payoff statement, an appraisal, a short-sale closing summary, an address change and a collections notice), Fyllyo filled 13 fields in 9 seconds. Each answer shows the lines it came from.

Fyllyo's review of a test Form 1099-C: box 1, the date of the identifiable event, filled as 07/15/2025, shown with the line from the lender's reporting authorization it came from.
  • The balance, the payment or the discharged amount. Reads only the amount the lender says was discharged, never a balance, a payoff or a payment. In the test, that was 53,420.
  • Which date is the identifiable event. Fills box 1 with the date the lender gives for the identifiable event, never a letter, approval, signature or preparation date.
  • Interest in the total, or interest on the account. Fills box 3 only with interest the lender says is included in box 2. In the test, that was 6,180, not the year’s interest paid or the daily charge.
  • The event code letter, not a status code. Copies only the code the lender assigns to box 6. In the test, that was F, not the collection system’s G2.
  • Which value is the fair market value. Fills box 7 with the valuation the lender designates for it. In the test, that was the 271,000 appraisal, not the sale, listing or assessed figures.
  • The sold property isn’t the debtor’s address. Reads the debtor’s current mailing address from the latest address record, never the property or a former address.
