If your brother "gave" you part of the proceeds of the sale, you do not have any tax. The recipient of a gift does not owe tax on the gift. But we have no details----was this a distribution of assets from your mother's estate? Or was the house left in a will to your brother alone and did he then choose to give part of the money to you? Details are needed.

Money that you receive as a gift is not taxable income to you, and you do not need to report it on your income tax return. Money that you gave as a gift to someone else is not deductible for your taxes.
