All properties in Dallas County pay a school equalization tax - it's part of the Dallas
County tax rate. All properties in the CFBISC pay CFBISD school taxes, all properties do. Be careful what you research on the internet, it's kind of like that GEICO commercial, not everything you read on the internet is accurate. When you pull up information on the DCAD sight, you are not seeing a tax bill, you are seeing an information sheet - and the possibility exists that it may not match the tax bill. Your agent should be able to calculate and estimate the correct taxes for any property, I do that for my clients on a daily basis. Ask your agent to calculate the right taxes for you.
