The adopted rate is 42 cents per $100 valuation, and represents the lowest rate in the greater Austin MSA with a population over 20,000. The effective rate is the rate the City would need to charge in order to produce the same amount of property tax revenues as last year while using the new valuations of the current year. Typically, property values appreciate from year to year. In most years, the increased value of a property means a lower tax rate could produce the same amount of revenue. For example, a home valued at $100,000 with a tax rate of 42 cents would produce $420 in property tax revenue. If in the following year, the home is now valued at $105,000, the effective rate would be 40 cents to produce the same $420 worth of revenue. The effective rate enables the public to evaluate the relationship between taxes for the prior year and for the current year. The rollback rate is the maximum tax rate the City can set before the taxpayers can petition for an election to reduce the tax rate. After adjustments for debt calculations, the rollback rate is equal to the effective rate times 8%, or in this example 43.2 cents for FY2018.
