Bug Report - 2024 Sched A, Tax and Interest Deduction Worksheet

[Deckard]

Line 1b Sales Tax Per State of Residence is providing a much lower result than the IRS online tool ( https://www.irs.gov/credits-deductions/individuals/use-the-sales-tax-deduction-calculator ) for the State of Florida, Nassau County. The 2024 TurboTax result is also lower than what the 2023 software provided, even though my 2024 Total available income is slightly higher. 

The entered State & Local Rate of 7% in column (4) breaks down properly into (5) State Rate of 6% and (6) Local Rate of 1%, but the calculated values are lower than expected.

Thank you for sending over your token, however it was partially obscured. Can you please resend it in a screenshot?

Please disregard my last message, we were able to get your token.

I compared the state sales tax in your return to the sales tax using the sales tax calculator at the IRS website. The amounts were the same. The income that you entered into the IRS website would have to be higher than the income being reported in TurboTax for the website to produce a higher deduction.

The income that's being used to calculate your tax deduction is your adjusted gross income plus your nontaxable IRA distributions. Is this the number you would expect to use, or were you using a different number on the IRS website? (If you're using TurboTax Online, click here for instructions on how to preview your 1040 to get these numbers.)

Your 2023 adjusted gross income is higher than your 2024 adjusted gross income. If your nontaxable IRA distributions were the same in 2023 as they were in 2024, your total 2023 income used for this calculation would be higher than 2024 which would explain why your 2024 deduction is lower than 2024.

I checked things again today, and saw that the IRS web site now matches TurboTax for the 2024 numbers. Digging further, the actual tables in Schedule A for calculating the amounts are lower in the IRS 2024 instructions than they were in their 2023 instructions.
