A property tax increase occurs when a property owner's tax bill is higher than the previous year. Increases can result from rising assessed property values, higher municipal tax rates to fund expanded services or cover cost increases, or increased provincial education levies. Even if your individual assessment stays flat, your taxes may rise if the municipality increases rates. Conversely, rising assessments might not increase your taxes if rates are lowered correspondingly. Property tax increases are common as municipal costs grow with inflation, population growth, and infrastructure needs. Understanding whether increases come from assessment or rate changes helps evaluate local tax policy.
