There are six rallies going on at the same time, one in each county. To express their objection to the reforms, which go into effect in April of next year, hundreds of tractors are taking to the highways in each area.
In Britain, protests are also occurring. Changes to inheritance taxes that were proposed in the most recent UK budget have infuriated farmers.
It implies that farmers who were previously spared from paying a large payment now have to pay it for the first time when they pass on land and other assets to the next generation.
Farmers worry that those who will inherit their land will have to sell it to cover the tax demand, which they have ten years to satisfy.
According to the British government, only the wealthiest landowners will be impacted due to a number of exemptions. However, a large number of typical family farms will be subject to taxes, according to the Ulster Farmers Union, which is organising the day of action.
The deputy president of the UFU, John McLenaghen, was present at the tractor run and rally in Derry.
"The fear is that some of the farm will have to be sold in order to pay the tax," he stated. "It's that easy, and that will render the farm unprofitable.
Additionally, if you want to pass the farm on to the next generation and they have ten years to pay the taxes, they will work for nothing but paying the taxes, which won't encourage them to farm.
"And that's where we're going to see a mass, we fear, a mass exodus out of our industry."
