I looked at the article but it didn't give any more info. I'm going to be purchasing land mid January; I wonder how much I'm saving when I split the tax 50/50 with the seller...
Edit: found another article with all the details. For me:
Measures to reduce the registration fee for housing rights and juristic acts in 2023 by reducing the registration fee for transferring real estate from 2 percent to 1 percent and reducing the registration fee for real estate mortgages from 1 percent to 0.01 percent for trading at Residential, including single houses, twin houses, row houses, commercial buildings, and condominiums (both first-hand and second-hand houses), only with the purchase price and the appraisal price not exceeding 3 million baht and the mortgage amount not exceeding 3 million baht per contract.
