Blue state Red State and it will get worse....
I can't speak for NY but my Father in Law owns land in NJ and the only way he keeps it is because he is under farmland/woodland Assessment. Much Lower taxes.
Requirements are a licensed forester putting together a timber plan and actively pursuing the plan. Which is not killer when you're waiting for a 4" white oak to become a tiber log.
There is a small earning off the land requirement but it's not to hard to sell your neighbor firewood and then buy some from him so you both meet the requirement. (just sayin)
I think NY has something similar. You need the advice of a Licensed NY private
forester. Your local tax accessor is not going to volunteer this info to you.
Here is some info on NY
"Forest Land Exemption
To encourage the long-term ownership of woodlands, Section 480-a of the Real Property Tax Law allows eligible owners of forest land to receive reductions in tax assessment. Landowners must own a minimum of 50 acres of contiguous forestland and be willing to commit the land to forest crop production. In addition, landowners must follow forest management plans that have been prepared by qualified foresters and approved by the New York State Department of Environmental Conservation (DEC). Owners of tracts certified by DEC must apply annually to their local assessors for the exemption. Landowners must comply with the program for nine years following the last year of commitment. Penalties may be imposed if a landowner fails to follow the approved management program or converts the land to a use that prevents continued forest crop production.
For more information about the forest land exemption, contact the New York State Department of Environmental Conservation, Division of Lands and Forests, Bureau of Private Land Services."
