Should homeowners pay higher taxes on "mansions" valued over £2m?

Yes, but only on properties valued at over £5m.

No, only those worth more than £10m

everyone should pay the same

Yes, especially since the government has issued the bedroom tax, targeting many lower income families. Having seen local residents forced to move out of their homes because they cannot afford the bedroom tax, they should also bring in the mansion tax. The wealthy have not seen any tax increases under this government, theirs have been cut, yet the lower class families have been far worse off especially due to services cut by the same government that's cutting taxes for the higher class.

Increase the threshold value, as in the current market, 2 million pounds is not actually that large of a house

Progressive Structure: Instead of a flat mansion tax, implement a graduated system (e.g. 0.3% on £2–3m, rising in tiers beyond that).
• Deferral Options: Allow low-income residents to defer payment until the sale of the property, preventing unfair burdens on the elderly or “cash-poor” homeowners.
• Council Tax Reform: Consider updating council tax bands to reflect modern property values, which may be a more effective long-term solution.
• Targeting Empty or Investment Properties: Apply higher rates to second homes or properties owned by non-resident investors, rather than all owner-occupied homes.

Yes, but only on properties that are purchased at that cost, not for those who have built their houses from the ground up & then have had their property valued at that price.
