Even ignoring the political impossibility of this, extending Capital Gains Tax (CGT) to a person's home is a non-starter.
Firstly, a couple are each taxed individually, and everyone has a CGT exempt amount each year - currently £11,100. So, if the family home is sold, owned jointly by a married couple, who has the tax liability, and what is the exempt amount? (Remember, it cannot be a joint liability.)
Secondly, it would be a bureaucratic nightmare for home-owners. Before any Chargeable Gain is calculated for CGT purposes, allowable expenses are deducted from the profit on the disposal, including repairs and enhancements. If CGT was extended to the principal private residence, every time the home-owner replaced anything on a like-for-like basis, or any improvements were made, these would be allowable deductions upon disposal - but you'd have to keep the documentation to prove it. How many times over the course of twenty years (or more) does the average householder redecorate, repair or make improvements to the home in which they live? That's a lot of receipts to keep - or wave goodbye to the money when they sell the house.
Thirdly, and, on the subject of fairness, perhaps the most important: It would disproportionately hit the lower paid.
Currently, the main exemptions from Capital Gains Tax are:
- chattels bought and sold for £6,000 or less
- wasting chattels (ie anything with an expected life span of fifty years or less)
- cars
- principal private residence (PPR), providing the owner has occupied the property throughout the period of ownership (although certain exemption periods apply.)
This means that pretty much everything owned by those on lower earnings is likely to be exempt from CGT. By making the PPR liable to Capital Gains Tax, you would be taxing the lower-paid on the only thing they own that is likely to bring in a large-enough profit to bring them into the CGT bracket. Not only that, but CGT is levied at only two rates; currently 18% and 28%. The higher rate kicks-in when the tax payer has used all of his or her Basic Rate Band (nominally £31,785 until April 5th, although the actual figure varies up or down depending on other things not pertinent here.) If CGT was levied on profits from the sale of one's PPR, even a modest wage earner would go way over their Basic Rate Threshold for the year and end up paying the higher rate of CGT on the lion's share of the profit they made. For CGT purposes, once the taxpayer has surpassed their Basic Rate Threshold, it doesn't matter whether they are earning £4,000 over the limit or £4 million.
To use someone I know as an example: they earn a modest £15,000 per annum, and have lived in the same terraced house for over 40 years. If the house was to be sold now, a profit of around £85,000 would be made (as the house was bought for a paltry £800!) In that scenario, the tax due according to the total income, would be as follows:
- £15,000 p.a. earnings - £17,702 tax liability - (118.01% of earnings)
- £20,000 p.a. earnings - £18,202 tax liability - (91.01%)
- £30,000 p.a. earnings - £19,202 tax liability - (64.01%)
- £40,000 p.a. earnings - £20,202 tax liability - (50.51%)
- £50,000 p.a. earnings - £20,440 tax liability - (40.88%)
- £100,000 p.a. earnings - £20,440 tax liability - (20.44%)
It would penalize the pensioner more than the millionaire. There
are reforms that could be made to CGT, but this is not one of them.
