You are trying to enter values in lines 6-10 of the Florida DR15 form, and it is showing an error that the “amount due” cannot be negative.
Florida will not allow you to file the return with a negative amount due, so TrustFile will not accept the return, to prevent filing issues.
The amount due is calculated by adding your total amount due for sales/services, taxable purchases, commercial rentals, and transient rentals, with estimated tax due (line 9), and subtracting your credits and estimated tax paid (line 8).
If the value in line 8 exceeds the total amount due from all of these other lines added together, then most customers typically change line 8 to equal that amount, and manually credit any remaining balance on their next tax return.
Full instructions on the form can be found on page 6 of the Department of Revenue’s DR15 instructions.
