Enacts the "mansion tax adjustment act"

This bill raises the sales price threshold for a special tax on high-value residential property sales from $2 million to a higher, annually adjusted amount. It affects sellers of homes or residential properties (including condos and co-ops) priced at or above the new threshold, which will increase yearly based on inflation. The tax rate remains at 1% on the amount exceeding the threshold, calculated using the Consumer Price Index. The adjustment mechanism automatically updates the threshold each year starting in 2027 to reflect rising prices. The bill takes effect immediately upon enactment.
