When property is sold, Montgomery County requires that Sellers provide an array of disclosures related to taxes and assessments. Tax bills are the best way to disclose this information. The link to access Montgomery County tax bills is: https://www.montgomerycountymd.gov/apps/tax/index.asp.
This page lets you print out a copy of the tax bill for the property and a tax rate chart which itemizes special assessment charges.
Printing this information for your sellers is a good way to ensure that proper disclosures are made to prospective buyers.
