Can I avoid CGT by making my second home my main residence before selling?

undefined If you own two homes, you can elect which is your main residence within 2 years. By doing so, the elected property gains PPR relief for the period of the election. You can then vary the election to switch main residence between properties, building up exempt periods on both. However, you must actually live in the elected property — HMRC looks at where you spend your time, where your family lives, electoral registration, etc. Simply making the election without genuine occupation is ineffective. Relevant legislation: TCGA 1992 s.222(5)-(10) — main residence election within 2 years; s.222(8) — variation of election.. Example: A client owning a London flat and a country cottage elected the cottage as their main residence for 3 years, then switched back to the flat. When they sold the cottage, 3 years of ownership was PPR-exempt (plus the final 9 months), reducing the taxable gain by 35%. Common mistake: Making a main residence election without actually moving. HMRC looks at the reality of occupation — electoral roll, council tax, utility bills, time spent. An election without genuine occupation may be set aside by HMRC.

What costs can I deduct from the gain when selling a second home?

undefined The gain is calculated as: sale price - selling costs - purchase price - acquisition costs - enhancement costs. Selling costs include estate agent fees, legal fees, and marketing costs. Acquisition costs include SDLT, legal fees, and survey fees. Enhancement costs include capital improvements (extensions, new kitchens, loft conversions) but NOT repairs, maintenance, or decoration. Keep receipts for all enhancement work — without evidence, HMRC may disallow the deduction. Relevant legislation: TCGA 1992 s.38 (allowable costs); s.39 (enhancement expenditure).. Example: A client selling a second home for £500,000 (bought for £300,000) had £5,000 in selling costs, £3,000 in original acquisition costs, and £40,000 in enhancement expenditure (a kitchen extension and loft conversion). The taxable gain was £500,000 - £5,000 - £300,000 - £3,000 - £40,000 = £152,000. Common mistake: Forgetting to deduct enhancement expenditure. Many sellers don't realise that capital improvements (extensions, structural work) reduce the taxable gain. However, repairs, decoration, and general maintenance do NOT qualify — only improvements that enhance the property's value.

Capital Gains Tax on Selling a Second Home

How much CGT you pay when selling a second home, holiday home, or buy-to-let property, and how to reduce it.

Quick Answer

Selling a second home triggers CGT at 18% (basic rate) or 24% (higher rate) on the gain, after deducting the £3,000 annual exemption. Unlike your main home, second homes don't qualify for full PPR relief. However, if you've ever lived in the property, you may get partial PPR relief for the periods of occupation plus the final 9 months, and potentially lettings relief. CGT must be reported and paid within 60 days of completion.

How CGT Works on Second Homes

A second home — whether a holiday home, buy-to-let, or inherited property — is subject to CGT on sale. The taxable gain is the sale price minus the purchase price, minus acquisition costs (stamp duty, legal fees) and enhancement costs (improvements, not repairs).

If you've never lived in the property, the full gain (after the annual exemption) is taxable. If you previously lived there, partial PPR relief may apply to the periods of actual occupation plus the final 9 months of ownership.

Main Residence Election Strategy

If you own two or more properties, you can elect which one is treated as your main residence for CGT purposes within 2 years of acquiring the second property. This can be a powerful planning tool:

The election must be made within 2 years of acquiring the second property
You must actually reside in the elected property (spend time there, have it registered for council tax, electoral roll, etc.)
You can vary the election — switching main residence between properties — to build up exempt periods on both
Once the 2-year window passes without an election, HMRC determines main residence based on the facts
This strategy works best when both properties have significant gains — by rotating residence, both gain partial PPR exemption

Lettings Relief (Restricted)

Lettings relief was heavily restricted from 6 April 2020. Previously worth up to £40,000 per owner (£80,000 per couple), it's now only available where the property was your main residence at some point AND you shared occupancy with the tenant (i.e., you let out part of your own home while living there).

For typical buy-to-let properties where you never lived in the property, lettings relief no longer applies. However, if you previously lived in the property and let it out, you may still get partial PPR relief for the period of occupation plus the final 9 months.

Relevant Legislation

PPR relief: TCGA 1992 s.222-226. Main residence election: TCGA 1992 s.222(5)-(10). Lettings relief: TCGA 1992 s.223C (restricted from 6 April 2020 by FA 2020 s.16). 60-day reporting: FA 2019 Sch.2.

Practical Example

A client sold a holiday home in Cornwall with a £200,000 gain. They had owned it for 10 years and never lived there. Full CGT applied: £197,000 at 24% = £47,280. We advised transferring 50% to the spouse before sale (tax-free transfer), using both annual exemptions (£6,000 total) and the spouse's lower-rate band. CGT reduced to £35,280 — a saving of £12,000.

Common Mistake

Not making a main residence election when owning two properties. Without an election within 2 years, HMRC decides based on facts — which may not be the property with the larger gain. This mistake alone can cost tens of thousands of pounds. Another common error is forgetting to deduct enhancement expenditure (extensions, renovations) from the gain — only improvements count, not repairs or maintenance.
