Chancellor John Healey has decided against lowering the mansion tax threshold to £1.5 million and will not align capital gains tax with income tax rates. These decisions provide relief to thousands of property owners ahead of the October 28 Budget.

The 145,000 homes spared by the £1.5 million threshold

The decision by Chancellor John Healey to maintain the current threshold for the High Value Council Tax Surcharge prevents a significant expansion of the tax base. According to the report, the government had been considering lowering the entry point from £2 million to £1.5 million, a move that would have ensnared an additional 145,000 properties. For those affected, this would have meant an annual tax burden ranging from £2,500 to £7,500 starting in 2028.

This reprieve is particularly significant for residents in London and the South East, where property values are inflated. As the report notes, many of the homes valued between £1.5 million and £2 million are standard family residences in expensive postcodes rather than luxury estates. For homeowners who purchased their properties in the 1980s or 1990s, a sudden annual surcharge could have forced a choice between taking on lodgers or selling their long-term family homes.

Avoiding the jump from 24 per cent to 45 per cent CGT

Landlords and second-home owners have avoided a potentially devastating shift in how profits are taxed upon the sale of an asset. Currently, higher and additional rate taxpayers pay a 24 per cent Capital Gains Tax (CGT), while basic rate taxpayers pay 18 per cent.. Had Chancellor John Healey aligned these rates with income tax, some sellers would have faced tax bills as high as 40 or 45 per cent.

The financial impact of such a change would have been stark. For instance, a landlord realizing a £100,000 gain (after the £3,000 annual allowance) would currently pay £23,280 in CGT. As reported, aligning this with income tax rates could have spiked that bill to between £38,800 and £43,650. By ruling out this alignment, the Treasury has opted not to aggressively squeeze the profit margins of the buy-to-let sector.

London's detached homes and the 7.7 per cent break-even struggle

This policy decision arrives at a time of extreme pressure on the UK rental market. A Money Mail investigation highlighted that a typical landlord with a 75 per cent buy-to-let interest-only mortgage now requires a gross rental yield of 7.7 per cent just to break even. When combined with higher mortgage rates and increased regulation, the environment has become increasingly hostile for small-scale investors.

The broader trend shows a growing number of landlords exiting the market. Analysts warned that if the mansion tax threshold had been lowered, one in four detached homes in London would have fallen under its scope. By avoiding these hikes, the government may be attempting to prevent a mass sell-off of rental properties that could further destabilize housing availability in the capital.

Will the 24 per cent CGT rate still climb to 28 per cent?

Despite the relief on the mansion tax and income tax alignment, the Treasury's objective remains plugging a £35 billion budget black hole. while the Chancellor has ruled out the most extreme CGT alignment, he has not completely closed the door on a more modest increase. There remains a possibility that the CGT rate for highr-rate taxpayers could still be raised, perhaps to 28 per cent.

The central question remains how the government will recover the necessary funds if these high-profile property taxes are off the table . the report focuses on the relief for homeowners, but it leaves open whether other assets or different tax brackets will be targeted to meet the £35 billion requirement by the October 28 deadline.
