From April 2026 there will be a charge of 20% inheritance tax on agricultural assets worth more than £1m for the first time, although the threshold for some farmers to pay would be £3m.
The protests were organised by campaign group Farmers To Action.
Farmers took part in a tractor convoy in Weston-super-Mare and others gathered outside the council offices on Euclid Street, Swindon.
Ms Broughton, who farms near South Petherton, Somerset said: “My children will be left with a farm that’s not viable, it’s going to be bought by a big investor who isn’t interested in the local community.”
