Multiple outlets report that Keir Starmer and Rachel Reeves have introduced plans for a mansion tax, with implementation potentially as early as April 2028. The reporting also says Greater Manchester Mayor Andy Burnham is considering changes to the policy, specifically by lowering the threshold that would determine which properties fall under the tax.

The articles reference Burnham’s earlier comments in which he described a mansion tax as representing “politics of envy,” suggesting he is now reconsidering his position or adapting the proposal in response to broader government plans. The coverage characterizes Burnham’s current discussions as aimed at making the tax apply to a wider range of homes by reducing the qualifying limit.

Taken together, the sources focus on the timeline for possible implementation under the new government framework and the reported direction of travel around the threshold, rather than on detailed rate structures or exemptions.
