The Scottish Government’s proposed new “Mansion Tax” will not take effect until April 2028 and is expected to apply directly to fewer than one in every hundred Scottish homes. It would therefore be easy for most homeowners, particularly here in Dunfermline and West Fife, to conclude that it has little to do with them. The Government consultation closed on 24 August and, as attention turns towards the detail and eventual legislation, the possible implications for the wider Scottish property market merit closer examination.
Despite its popular description, this is not in fact a separate new tax. The proposal is to introduce two additional Council Tax bands: Band I for properties valued between £1 million and £2 million and Band J for those worth more than £2 million. Subject to legislation, they would take effect from 1 April 2028, with potentially affected properties assessed according to their estimated market value at 1 April 2026.
The final charges have still to be determined but for consultation purposes, the Government illustrated annual charges of approximately £4,770 for Band I and £7,650 for Band J – average increases of around £720 and £3,600 respectively compared with the present highest band. It estimates the change would raise approximately £12 million to £16 million each year for local authorities.
For the overwhelming majority of our clients, the prospect of receiving a Band I or Band J bill is we accept extremely remote. Recent figures put the average selling price in Dunfermline at approximately £228,000, with three-bedroom houses averaging around £248,000. Across West Fife and Kinross, the recent average has been approximately £223,000.
That is clearly a very different market from areas where seven-figure sales are commonplace. Registers of Scotland recorded only 392 residential sales above £1 million across Scotland during 2025/26, more than half in Edinburgh. Why, then, should a homeowner in Dunfermline care about a tax aimed at properties worth four or five times the value of their own?
The answer lies in the interconnected nature of the property market and, perhaps, in a version of the “butterfly effect”: a relatively small change in one place can ultimately have consequences somewhere seemingly far removed from it. Nobody is suggesting that an additional Council Tax charge on a £1 million Edinburgh townhouse will suddenly change the value of a £225,000 Dunfermline house. The local property market is however far less “local” than you might think and frequently operates through interconnected transactions across wide geographical areas. Here in Dunfermline, having someone in the chain buying or selling in Edinburgh is, in fact, very common.
Consider an ordinary property chain. Someone sells a £225,000 home and moves to a £350,000 property. Those sellers move to something at £500,000, whose owners buy at £750,000. Further along that chain somebody may ultimately purchase at £1 million or more. The individual homes may have little in common, but their transactions can be directly connected. Anything which materially affects people’s willingness to buy, sell or move can therefore have consequences beyond the section of the market at which it is directed.
The wider tax picture.
This becomes particularly interesting when the proposal is considered alongside Scotland’s existing property taxes. Land and Buildings Transaction Tax already produces substantial revenue when properties change hands, with higher-value transactions making a disproportionately significant contribution. Recent independent analysis estimates that residential transactions above £1 million currently generate around £65 million a year in LBTT.
That compares with the £12 million to £16 million the Scottish Government expects the new Council Tax bands to raise annually. It would be wrong to suggest that £65 million of LBTT revenue is somehow placed at risk by the new bands. It plainly is not. The comparison simply illustrates that the calculation should consider not only how much additional revenue a measure raises, but whether it changes buyer and seller behaviour and, consequently, transaction numbers.
At the lower end of the proposed bands, the additional cost may prove relatively insignificant. The illustrative Band I increase is around £720 per year compared with Band H – approximately £60 per month. It is questionable whether that would materially influence someone contemplating a million-pound home. For properties above £2 million, however, the proposed differential is considerably greater.
There may also be a psychological effect around the £1 million threshold. Buyers consider not simply price but LBTT, mortgage costs and the continuing costs of ownership. Whether a new Council Tax boundary at £1 million becomes another figure around which purchasing decisions are made remains to be seen.
Why the ripple effect matters.
Importantly, any ripple effect need not be negative. If the additional cost of owning a property above £1 million persuaded some prospective purchasers to concentrate instead on homes below that level, demand in the upper-middle market could increase. Where demand already exceeds supply, that could potentially support prices rather than depress them, with the effect perhaps travelling further down the property chain.
Whether that happens to any meaningful extent is another matter. An additional £60 per month seems unlikely, on its own, to transform the decision of someone contemplating a million-pound home. Nevertheless, it demonstrates why the consequences may be less straightforward than simply asking how many households will pay the new charge.
The wider issue is mobility. A healthy property market relies upon people being willing and able to move. First-time buyers enter, allowing existing owners to take their next step. Families trade upwards, while others downsize or relocate. Those individual decisions collectively create the chains upon which thousands of transactions depend.
Scotland recorded more than 104,000 residential sales during 2025/26, with the total value of property changing hands reaching a record £24.3 billion. West Fife, with recent average selling prices around £223,000, bears little resemblance to the £1 million-plus sector targeted by the proposed bands. Yet they are not entirely separate ecosystems.
A relatively small intervention at the top of the market does not automatically produce a large consequence further down – and may ultimately produce virtually none. But if it alters enough decisions about whether, when or where people move, those decisions can ripple into other transactions and price brackets.
That is why the proposed Scottish Mansion Tax deserves attention now rather than in April 2028. For almost every homeowner in Dunfermline and West Fife, the new bands will have no direct effect whatsoever. The more interesting issue is their indirect effect.
Should Scotland be able to raise additional revenue from a very small number of its most valuable homes without materially affecting transactions, the wider consequences may prove negligible. If the policy does change behaviour at the upper end, however, its impact may not necessarily stop at the front door of Scotland’s million-pound homes. In an interconnected property market, even a relatively small flutter of the wings can sometimes be felt rather further away.
