Hundreds of protesters are to take part in a demonstration in Corby on Saturday against the so-called bedroom tax.
The protest is one of 50 taking place in towns and cities across the UK as part of a national day of action.
In Corby, the rally has been organised by Karen McCluskey and borough and county councillor John McGhee.
Corby and East Northants MP Andy Sawford will be among those speaking at the demonstration outside The Cube, starting at 12.30pm.
Karen said: “We are expecting hundreds of people to turn out and protest against this immoral tax on those least able to pay.
“Whether people are affected by it or not, we want everyone to take part in this peaceful demonstration to show the strength of feeling there is against the tax.”
Cllr McGhee said: “The bedroom tax will hit the most vulnerable in society. It is immoral and a disgrace.”
Organisers were due to hold the protest last Saturday but called it off as a mark of respect for Lance Corporal James Ashworth, of Corby, who has been awarded the Victoria Cross after being killed in action in Afghanistan.
Plans for a parade in his honour on the same day had to be cancelled because of the bad weather.
Corby has 970 council and social housing tenants who will have their housing benefit cut because their homes are deemed under-occupied.
