In NYS, a transfer tax equivalent to .4% of the sale price (rounded up to the next $500) is payable upon the transfer of real estate
Erie County levies a surcharge equivalent to .5% of the sale price (again, rounded up to the next $500) on the transfer tax. Supposedly, this surcharge goes to the NFTA.
So, for a house in Erie Co. that sells for $250k, the total transfer tax is $2250. Generally, the Seller pays this fee.
