Here is the link for the Spindle Tax Limitation Calculator (SB12)
https://tools.spindlemedia.com/TaxLimitationCalculator
1. First you choose your school district. In this case I used Mesquite ISD
2. Next you enter the Homestead-able Taxable value for the school for each year from 2018 through 2022 (this can be found in Appraisals in Taxoffice4).
3. Then you enter the 2018 ceiling amount, and unless the Ceiling has an adjustment you set the 2019 - 2023 Ceiling Adjustments values set to 0.
4. The Ownership %'s, and MCR values should already be filled out.
5. Enter the 2023 Total tax rate for the school, you can also find this in Appraisals in Taxoffice4
6. Then you click the submit button
7. The SB12 Reduction is calculated by taking the 2022 value * the 2022 MCR - the 2023 Value * the 2023 MCR and \ by 100 or 110,230 x (2022 MCR (0.8046) - 2023 MCR (0.6192)) / 100
8. The SB2 Reduction is calculated by taking the addition of tax rate * the exemption differences or
(15,000 x 1.2846 / 100) + (60,000 x 1.0992 / 100)
