Capital Gains Tax on Garages: How Much You'll Owe When You Sell

When you sell a garage at a gain, HMRC takes a cut. The amount of the cut depends on how the garage was held, who you are, what reliefs apply, and what other gains you have crystallised in the same tax year. Most garage investors underestimate the eventual tax bill because the gain compounds quietly over the hold period.

This is the 2026/27 calculation, with the structural choices that move the bill.

How garage CGT works

Capital gains tax on a garage sold by a UK individual in 2026/27:

The gain. Sale proceeds minus acquisition cost minus enhancement expenditure (capital improvements) minus selling costs. Routine repairs are revenue, not capital, and do not reduce the gain. Conversion costs and major improvements do.

The annual exempt amount. Each individual has a £3,000 CGT-free allowance per tax year for 2026/27 — sharply reduced from the £12,300 it was in 2022/23. Couples with both spouses on the title get £6,000.

The applicable rate. Garages held by individuals are non-residential property for CGT purposes. The rates in 2026/27:

• Basic rate taxpayers: 10% on the portion of gain that falls within their unused basic-rate band, 20% on the portion above.
• Higher and additional rate taxpayers: 20% flat.
• The 2024 changes increasing residential CGT rates do not apply to garages classed as non-residential or chattels.

The reporting deadline. Property gains must be reported and paid within 60 days of completion via the Capital Gains Tax on UK property service. Failure to report attracts penalties.

A worked example

A higher-rate-taxpayer investor sells a garage in 2026/27:

• Bought 7 years ago for £15,000.
• Sold for £24,000.
• Paid £1,200 in initial acquisition costs (legal, stamp duty, etc.).
• Spent £2,500 on a door replacement and roof refurbishment 3 years in (capital improvements).
• Paid £1,400 in selling costs (auction fees, legal).

The gain. £24,000 − £15,000 − £1,200 − £2,500 − £1,400 = £3,900.

Annual exempt amount. £3,900 − £3,000 = £900 of taxable gain.

Tax at 20%. £180.

That is a manageable bill for a single garage at modest gain. The picture changes when the gain is bigger, or the investor is selling multiple garages in the same year.

What goes wrong at scale

Three patterns that produce surprise CGT bills.

Selling multiple garages in one tax year. The £3,000 annual exempt amount applies once per individual per year, not per asset. Sell three garages with £3,000 of gain each, and you are taxed on £6,000 of gain — only the first £3,000 is exempt.

Long holds compound the gain. A garage bought at £15,000 in 2010 and sold at £35,000 in 2026 has a £20,000 gain (before deducting costs). Even at the basic rate, that is a £3,400 tax bill. At the higher rate, £4,000.

Selling alongside other gains. If you sell a garage in the same year you sell shares with a £4,000 gain, the £3,000 annual exempt amount does not double — it covers the highest-rate gain first, leaving the rest taxed in full.

The structural choices that move the bill

Six choices, in rough order of effect.

Hold in a Ltd company. Companies do not pay CGT — they pay corporation tax on chargeable gains, currently at 19-25%. The annual exempt amount does not apply, but the rate is lower for additional-rate taxpayers. Crucially, a company can also defer the gain through internal reinvestment without crystallising tax. For investors planning to recycle proceeds into more garages, this is structural.

Spousal transfer before sale. Transferring half the garage to a lower-rate-taxpayer spouse before selling can save 10 percentage points of CGT on half the gain. Transfers between spouses are at no-gain-no-loss for CGT, so the transfer itself does not trigger tax. Specific advice essential.

Stagger sales across tax years. Selling one garage in March and one in May puts each into a different tax year and gives you £6,000 of annual exempt amount instead of £3,000. Simple, low-friction, often forgotten.

Use up the annual exempt amount each year. If you have £3,000 of headroom in the AEA you do not otherwise use, harvesting a small gain (selling a garage at £3,000 of gain into a year where you have no other gains) costs nothing in tax and resets your base cost on the asset if you re-buy. Niche, but effective for portfolio housekeeping.

Realise capital losses. If you have other capital losses (failed share investments, losses on other property), they offset garage gains. Losses unused in the year of disposal can be carried forward indefinitely.

Death and the CGT uplift. Garages held at death are revalued to market value for the heirs (the "uplift on death"), and the historic gain is wiped out for CGT purposes. This is the only fully tax-efficient way to eliminate large embedded gains, although it requires you to die first.

What we'd actually do

For investors in the higher rate or above, with growing portfolios, hold in a Ltd company — the corporation-tax route on gains is more predictable and the deferral options are richer.

For basic-rate taxpayers with one or two garages, personal ownership is fine until the portfolio scales, but watch the annual exempt amount each year and consider the spousal transfer if your spouse is in a lower band.

For everyone, plan the tax year of disposal in advance. Garage sales are not usually time-critical, so staggering disposals across tax years is essentially free.

The CGT bill on a single garage sold at modest gain is small. The CGT bill on a portfolio liquidated in a single year by a higher-rate taxpayer is considerable. The structural choices above are what determines which scenario you live with.
