There are two possible reasons for the change. The first is that another taxing entity (school district, Davis County, etc.) has gone through the Truth-in-Taxation process and raised their rates on one or more years which would increase your taxes. The second is that your property has increased in value more than other properties. When the property value of the City increases, the tax rate automatically decreases which gives the City the same revenue from year to year. However, if your property increases in value at a rate higher than the tax rate decreased then you will see a tax increase. The City will not see that increase because another property’s value would have been decreased or become tax exempt which would mean a tax decrease, and result in no change to City revenue.
Below is an example of a city that experiences market value inflation. You will notice that even though the taxable values increases, the tax rate decreases, causing the total tax revenue collected by the city to remain the same.
