Second home tax is not one single charge. In the UK it is the combination of a 5% Stamp Duty Land Tax surcharge on additional homes in England and Northern Ireland, a possible council tax premium of up to 100%, Capital Gains Tax when you sell, and Income Tax on any rent you earn. Together, these can add tens of thousands of pounds to the lifetime cost of a holiday cottage or buy-to-let flat.
Owning a second home can be an exciting opportunity, whether you want a coastal bolthole, a rental income stream or a base for retirement. This guide explains each tax in plain English, shows a worked stamp duty example, compares the rules across the UK nations and the US, and sets out the legitimate ways owners reduce what they pay.
Second Home Tax at a Glance
| Tax or charge | When it applies | What to expect (UK) |
|---|---|---|
| Stamp Duty Land Tax (SDLT) surcharge | On purchase of an additional residential property in England or Northern Ireland | 5% on top of standard rates on every band, for purchases of £40,000 or more |
| Land Transaction Tax (Wales) | On purchase of an additional home in Wales | Separate higher residential rates set by the Welsh Government |
| Additional Dwelling Supplement (Scotland) | On purchase of an additional home in Scotland | 8% of the total price on top of LBTT |
| Council tax premium | Every year you own a furnished home that is nobody’s main residence | Up to 100% extra in England and Scotland where the council adopts it; up to 300% in Wales |
| Income Tax on rent | If you let the property | Profit taxed at your marginal rate; mortgage interest only gets a 20% tax credit |
| Capital Gains Tax (CGT) | When you sell or give the property away | 18% or 24% on gains above the £3,000 annual exemption, reported and paid within 60 days |
| Inheritance Tax | On death, as part of your estate | Counts towards your estate; the residence nil-rate band applies to only one home passed to direct descendants |
What Is Second Home Tax?
“Second home tax” is shorthand for the higher rates and extra charges that apply once you own more than one residential property. HMRC and local councils do not issue a bill with that name. Instead, several existing taxes are applied more heavily to additional homes, both when you buy and every year you hold the property.
The policy aim is to cool speculative buying, keep homes available for local residents and first-time buyers, and raise revenue. Whatever the motive, the practical effect is the same: a second property costs noticeably more to buy, hold and sell than your main home.
Who counts as owning a second home?
For stamp duty, the test is simple: if, at the end of the day of completion, you (or your spouse or civil partner) own more than one residential property worth £40,000 or more anywhere in the world, and you are not replacing your main residence, the higher rates usually apply. This catches people who might not think of themselves as landlords, such as someone who inherited a share of a parent’s house or who kept a flat abroad.
Stamp Duty on Second Homes in England and Northern Ireland
Since 31 October 2024, the higher rates for additional dwellings add 5 percentage points to every SDLT band (it was 3% before that date). From 1 April 2025, the standard nil-rate threshold returned to £125,000, which makes the surcharge bite from the first pound.
| Portion of price | Standard rate | Second home rate |
|---|---|---|
| Up to £125,000 | 0% | 5% |
| £125,001 to £250,000 | 2% | 7% |
| £250,001 to £925,000 | 5% | 10% |
| £925,001 to £1.5 million | 10% | 15% |
| Above £1.5 million | 12% | 17% |
Worked example: a £300,000 second home
- As a main home: 0% on the first £125,000, 2% on the next £125,000 (£2,500) and 5% on the final £50,000 (£2,500) = £5,000.
- As a second home: 5% on £125,000 (£6,250), 7% on £125,000 (£8,750) and 10% on £50,000 (£5,000) = £20,000.
- The surcharge alone costs £15,000, which is 5% of the price, and it must be paid within 14 days of completion.
Replacing your main residence and refunds
If you buy a new main home before selling your old one, you pay the higher rates at first, but you can claim the surcharge back if you sell the previous main home within three years. Many buyers miss this, so keep your completion statements and diary the deadline for the refund claim.
Wales and Scotland
Wales uses Land Transaction Tax with its own higher residential rates, and Scotland charges the Additional Dwelling Supplement (8% of the whole price) on top of Land and Buildings Transaction Tax. If you are buying across the border, check the relevant revenue authority’s calculator rather than relying on English figures.
Council Tax on Second Homes
Second homes are usually charged full council tax, with no single-person discount. On top of that, councils can now add a premium:
- England: from 1 April 2025, councils can charge up to a 100% premium on furnished second homes that are no one’s main residence, which doubles the bill. Long-term empty homes can face higher premiums still.
- Wales: councils can set premiums of up to 300%, and several holiday hotspots use high rates.
- Scotland: councils have been able to charge up to 100% extra on second homes since April 2024.
Some exceptions exist, for example job-related homes or properties being actively marketed for sale or let, but they differ by council. Check your local authority’s published policy before you buy, especially in coastal and national park areas where premiums are most common.
Capital Gains Tax When You Sell
Your main home is normally protected from Capital Gains Tax by Private Residence Relief. A second home is not, so any increase in value is taxable when you sell or gift it.
- Rates: 18% for gains falling within the basic-rate band and 24% above it.
- Annual exempt amount: £3,000 per person, so joint owners get two allowances.
- Deductions: buying and selling costs (legal fees, stamp duty, estate agent fees) and the cost of improvements such as an extension, but not routine repairs.
- Deadline: UK residents must report the sale and pay any CGT due within 60 days of completion using HMRC’s property account.
If you genuinely live in both properties, you can nominate which one is your main residence for CGT purposes. The election generally has to be made within two years of starting to own a second residence, and the final nine months of ownership of a former main home are still covered by relief.
Renting Out a Second Home: Income Tax Rules
Letting the property, whether to long-term tenants or holidaymakers, makes the profit taxable at your marginal Income Tax rate. You can deduct allowable costs such as letting agent fees, insurance, repairs, utility bills you pay and accountancy fees.
Mortgage interest is treated differently. Individual landlords cannot deduct it from rental income; instead they receive a tax credit worth 20% of the interest. Higher-rate taxpayers therefore lose part of the relief. The special furnished holiday lettings regime was also abolished from April 2025, so short-term lets are now taxed much like other rental property.
Second Home Tax in the United States
Readers with property across the Atlantic should note that the US has no tax officially called a second home tax. Property taxes are set locally and apply to second homes in the same way as main homes. The Internal Revenue Service allows mortgage interest on a qualifying second home to be deducted within overall limits, but renting the home out for more than a short period changes how it is treated. The US home-sale exclusion applies only to a principal residence, so gains on a second home are generally taxable. UK residents who own US property may also have UK reporting duties, so cross-border advice is worth paying for.
Why Governments Impose Second Home Taxes
Housing market stability
Higher purchase taxes reduce the appeal of buying multiple properties purely for capital growth, which is intended to stop investors bidding prices beyond the reach of local buyers.
Fairer tax distribution
Because additional homes are concentrated among wealthier households, governments see surcharges as a progressive way to raise money without increasing taxes on ordinary homeowners.
Fewer empty homes
Council tax premiums are aimed at villages and towns where a high share of properties sit empty for much of the year. The extra charge nudges owners to let the home, use it more, or sell to someone who will live there.
The Full Cost of Owning a Second Home
Tax is only part of the picture. When budgeting, list every recurring and one-off cost:
- Stamp duty surcharge and legal fees on purchase
- Council tax, potentially with a premium
- Buildings and contents insurance, which costs more for homes left empty or let to holidaymakers
- Maintenance, utility standing charges and gardening while you are away
- Letting or management fees and safety certificates if you rent it out
- Income Tax on rental profit and CGT on eventual sale
A useful exercise is to calculate the yearly holding cost and divide it by the number of nights you actually expect to stay. Many owners find a second home works out far more expensive per night than holiday rentals, which helps decide whether to let it.
How to Reduce Second Home Tax Legally
You cannot avoid these taxes entirely, but careful planning can cut the bill:
- Time the purchase of a replacement home. If you are moving, selling first avoids the stamp duty surcharge, or use the three-year refund window.
- Use both spouses’ allowances. Transfers between spouses and civil partners are usually free of CGT, so holding the property jointly can use two £3,000 exemptions and two basic-rate bands.
- Make the main residence election on time. If you live in both homes, nominating the one likely to grow more in value can save significant CGT.
- Keep improvement receipts. Capital spending such as a new kitchen or loft conversion reduces the taxable gain.
- Claim every allowable letting expense and keep records for at least five years after the filing deadline.
- Check council exemptions before the premium applies, especially if the home is being marketed or used for work.
Tax rules change often, and the right structure depends on your income and family circumstances. Speak to a qualified tax adviser or chartered accountant before buying, transferring or selling. HMRC’s official guidance on residential stamp duty rates is the best starting point for checking current figures.
Key Questions to Ask Before Buying a Second Home
- Can I pay the surcharge in cash on top of my deposit?
- Does the local council charge a second home premium, or plan to?
- Will rental income cover the mortgage after tax, given the 20% interest credit?
- How long do I intend to keep it, and what CGT might I face on sale?
- Is the local market stable, or heavily dependent on tourism?
- Does my mortgage lender permit letting, and does my insurer cover it?
Bottom Line on Second Home Tax
Second home tax raises the cost of buying, holding and selling an extra property at every stage: 5% extra stamp duty in England and Northern Ireland, possible doubled council tax, Income Tax on rent and CGT at up to 24% on sale. Run the numbers for all four before you make an offer, then use spouse allowances, timely elections and good record-keeping to keep the bill as low as the rules allow.

Frequently Asked Questions
How much is stamp duty on a second home in the UK?
In England and Northern Ireland, you pay standard SDLT plus a 5% surcharge on every band for additional homes costing £40,000 or more. On a £300,000 second home that means £20,000 rather than £5,000. Wales and Scotland run separate systems with their own higher rates.
Can I get the second home stamp duty surcharge back?
Yes, if you paid the higher rates because you bought a new main home before selling your previous one. Selling the old main home within three years lets you claim a refund of the surcharge from HMRC.
Do I pay double council tax on a second home?
Possibly. Councils in England and Scotland can add a premium of up to 100% on furnished second homes, effectively doubling the bill, while Welsh councils can charge up to 300%. Whether you pay depends on your council’s policy and any exceptions that apply.
What Capital Gains Tax rate applies when I sell a second home?
Gains on residential property are taxed at 18% within the basic-rate band and 24% above it, after the £3,000 annual exempt amount. You must report the sale and pay the tax within 60 days of completion.
Can I choose which home is my main residence?
If you genuinely live in both properties, you can nominate one as your main residence for Capital Gains Tax. The nomination usually has to be made within two years of acquiring the second residence, so act promptly.
Is it possible to have two residential mortgages?
Subject to affordability and lender criteria, many people do hold more than one residential mortgage. Lenders will look closely at your income and existing commitments, and a buy-to-let mortgage is normally required if you plan to rent the property out.
