Richard Blackburn, a dairy farmer from Nantwich, said farmers already paid “a lot of tax” and this was “a kick in the teeth”.
The change would mean he would have to sell all or part of his farm, he said.
Farming was “quite hard as it is”, generally working on low returns, and this insecurity would deter his children from taking over the business, he added.
“This tax is just the wrong one completely,” he said.
“There must be other places where they can look.”
The government has been approached for a response to the protest.
