For New Mexico, Turbo Tax seems to be using the 2024 PIT-ADJ Instructions, instead of the 2025 PIT-ADJ Instructions. As a result, it is miscalculating the net capital gains deduction limit to be 40% up to $1,000,000, instead of $2,500. The 40% limit now only applies to net capital gain income from the sale of a business that is allocated or apportioned to New Mexico.
