I just received my invoice and the claimed savings does not make sense if I calculate the difference in taxes from last year to this year.

In order to calculate the actual savings generated by a reduction in assessment you must calculate what your property taxes would have been at the originally assessed value before filing the appeal and what they are at the reduced assessed value using the tax rates appearing on the bills issued with the reduced assessment. All of our invoices provide these details for your review. The reason you cannot calculate the savings in taxes by comparing this year’s bill to last year’s, is that the tax rates increase every year. Accordingly, if you do not challenge your assessment, your tax bills will naturally increase every year.
