A plain-English definition of Montgomery County property tax and why a bill can change.
Last updated: 2026-05-19
Independent and unofficial. Source-linked term.
Property tax is a tax on real property. In Montgomery County, the real property tax rate is set each year by the County Council and applied to assessed value.
The rate is not the whole bill. The levy year, tax class, assessed value, credits, municipality or special district, and property-specific charges can also affect what is due.
Why It Matters
Property tax is a major county revenue source and a direct bill for many residents, but the budget category and the household bill are not the same thing.
Common Misunderstanding
A tax bill can change even when a headline rate does not. Assessment changes, credits, and special charges can also change the amount due.
