Box 6. Shows certain real estate tax on a residence charged to the buyer at
settlement. If you have already paid the real estate tax for the period that
includes the sale date, subtract the amount in box 6 from the amount already
paid to determine your deductible real estate tax. But if you have already
deducted the real estate tax in a prior year, generally report this amount as
income on the “Other income” line of Schedule 1 (Form 1040). For more
information, see Pub. 523, Pub. 525, and Pub. 530
