A petition to cut beer duty is being stepped up amid fresh warnings of pub closures across the UK.
A protest, backed by the Long Live The Local campaign group, is being held outside Parliament on Thursday, over complaints that pubs are overtaxed.
Spokesman David Cunningham said: "Pubs employ almost 600,000 people, and on average a pub contributes over £100,000 to its local economy.
"Despite this, pubs are overtaxed, with each pub paying an average of £140,000 every year through a range of taxes, one of which is beer duty.
"Beer duty in the UK is 11 times higher than in Germany and Spain, which is why we're asking for a modest cut to save thousands of jobs and help protect the future of local pubs."
The group said British beer drinkers have already paid as much in duty as those in Germany will pay all year, despite the fact that German drinkers consume nearly double the amount annually.
Pub owner and Great British Bake Off winner Candice Brown joined the protest.
She said: "Pubs are the beating heart of cities, towns and villages up and down Britain - they not only provide jobs but a place where everyone and anyone can meet and socialise. If the Chancellor does not act now, he is set to damage not only businesses but communities as well."
The new Chancellor, Rishi Sunak, is being urged to cut beer duty in next month's Budget, with the campaign group warning that taxes are putting local pubs at risk of closure.
Currently one in three pounds spent in the pub goes to the taxman.
Beer Duty raises a whopping £3.4billion a year for the Treasury - four times more than any other European nation.
Spain brews almost as much beer as the UK, yet locals pay 11 times less Beer Duty.
In Britain, pub-goers pay 54p in Beer Duty for every for every pint purchased. In Spain, you would pay only 5p for the same drink.
