You're not allowed to deduct sales tax where the rate was "slightly different". The law was written that way, on purpose.
Generally, you can deduct the actual state and local general
sales taxes you paid in 2024, but only if the tax rate was the same as the general sales tax rate.
Exception: You can deduct the sales tax paid on the following items up to the general sales tax rate:
- Vehicles
- Off-road vehicles
