How to Avoid or Reduce Stamp Duty: 7 Legal Strategies
You cannot avoid stamp duty entirely on most property purchases, but there are legitimate ways to reduce the amount you pay. This guide covers every legal strategy available in 2026, including specific methods for second home buyers.
Can You Legally Avoid Stamp Duty?
Stamp duty (SDLT) is a mandatory tax on property purchases in England and Northern Ireland. There is no blanket exemption for most buyers. However, HMRC provides several legitimate reliefs, thresholds, and structural options that can significantly reduce your bill.
The difference between tax avoidance (legal) and tax evasion (illegal) matters. Every strategy in this guide is based on reliefs and rules that HMRC explicitly recognises. Aggressive schemes that artificially reduce your liability can result in penalties and criminal prosecution.
Key Principle
The best way to reduce stamp duty is to use reliefs you genuinely qualify for, not to create artificial structures. HMRC has broad anti-avoidance powers under the General Anti-Abuse Rule (GAAR) and can challenge any arrangement whose main purpose is avoiding tax.
How to Reduce Stamp Duty on a Second Home
The 5% additional property surcharge is the biggest cost driver for second home buyers. Here are the most effective strategies:
1. Sell your existing property first
If this is a replacement main residence, sell before buying to avoid the surcharge entirely. On a £400,000 purchase, this saves £20,000.
2. Claim the 36-month refund
If you cannot sell first, pay the surcharge and claim a refund once the old property sells within 3 years.
3. Check the property value
The surcharge only applies where the chargeable consideration is £40,000 or more, so a purchase below that figure does not attract it. This applies to some rural or remote properties, garages, or small plots of land.
4. Do not buy through a company to save stamp duty
A limited company does not avoid the surcharge. Companies pay the higher rates on every residential purchase of £40,000 or more, even if they own nothing else, and above £500,000 a flat 17% applies unless a relief (for example for a property rental business) brings it back to the higher rates. Any case for a company rests on income tax, not stamp duty.
Use the second home calculator to see how the surcharge affects your specific purchase, and read the full second home guide for detailed rules.
Strategy 1: First-Time Buyer Relief
If you have never owned property anywhere in the world, first-time buyer relief provides the largest stamp duty saving available. You pay:
Properties above £500,000 do not qualify for any FTB relief, and you pay standard rates on the entire amount.
Potential Saving
On a £300,000 property: save £5,000 (standard buyer pays £5,000, FTB pays £0)
On a £450,000 property: save £5,000 (standard buyer pays £12,500, FTB pays £7,500)
£5,000 is the maximum the relief can save, and it applies at any price from £300,000 up to £500,000. Above £500,000 the relief is lost entirely.
Use the first-time buyer calculator to see your exact saving. If you are buying jointly with someone who has owned property before, FTB relief is lost for the entire purchase. Check your FTB eligibility first.
Strategy 2: Replacement Main Residence Refund
If you are buying a new main home before selling your current one, you will initially pay the 5% additional property surcharge. However, you can claim a full refund of that surcharge if you sell your previous main residence within 36 months.
How It Works
Step 1: Buy new home, pay SDLT including 5% surcharge
Step 2: Sell your previous main residence within 36 months
Step 3: Claim online or on form SDLT16, so that HMRC receives it within 12 months of the sale (or of the new home's filing date, if later)
Result: Full refund of the 5% surcharge portion
Potential Saving
On a £400,000 property, the 5% surcharge adds £20,000. If you sell your old home within 36 months, you reclaim the full £20,000.
See the full 36-month refund rule guide and the refund claim process for step-by-step instructions.
Strategy 3: Negotiate the Purchase Price Down
Stamp duty is calculated on the purchase price. Even small price reductions near band thresholds can produce meaningful savings.
| Price Paid | Standard SDLT | Saving vs. Higher Price |
|---|---|---|
| £260,000 | £3,000 | Baseline |
| £250,000 | £2,500 | Save £500 |
| £935,000 | £37,250 | Baseline |
| £925,000 | £36,250 | Save £1,000 |
While stamp duty uses progressive bands (so there are no dramatic jumps), negotiating a lower price always reduces SDLT. Use the stamp duty calculator to model different prices before making an offer.
Strategy 4: Separate Fixtures and Fittings
SDLT is charged on the price of the land and buildings, not on moveable items. If the sale includes items like curtains, carpets, freestanding appliances, or garden furniture, these can legitimately be excluded from the SDLT-liable amount.
Can Be Excluded
- Freestanding appliances (washing machine, fridge)
- Curtains and blinds
- Loose carpets and rugs
- Freestanding furniture
- Garden ornaments and pots
Cannot Be Excluded
- Fitted kitchen units
- Built-in wardrobes
- Central heating system
- Bathroom suites
- Fitted carpets (debated, but HMRC often includes)
HMRC Scrutiny Warning
Valuations must be genuine and reasonable. A common figure is £5,000 to £15,000 for typical contents. Claiming £50,000 of fixtures in a £300,000 property will attract HMRC attention. Keep an itemised list with realistic valuations.
Strategy 5: Time Your Transactions
Timing can determine whether you pay the 5% additional property surcharge:
- Sell before you buy: If you sell your current main residence before completing on the new purchase, you own only one property at completion and avoid the surcharge entirely. You may need temporary rental accommodation.
- Complete on the same day: If the sale of your old home and purchase of your new home complete on the same day, you do not pay the surcharge. This is common in property chains but carries risk if the chain breaks.
- Buy before you sell: You pay the surcharge upfront but can claim it back once you sell the old property within 36 months.
For detailed timing guidance and worked examples, see the home mover guide.
Annexe, land or an old home not sold yet?
These are the purchases where a standard calculator can get your stamp duty wrong. Get it checked before you exchange.
Strategy 7: Mixed-Use Property Classification
Properties with both residential and commercial elements qualify for non-residential SDLT rates, which top out at 5% instead of 12%. This can apply to:
- Flats above shops or offices bought in the same transaction
- A house sold with land that is genuinely used for a separate commercial purpose, such as farmland let to a farmer, rather than forming part of the garden or grounds
- Live/work units with dedicated commercial space
- Properties that include a separate commercial unit, such as a shop, office or workshop in business use (an annexe let as holiday accommodation is still residential)
HMRC Crackdown
HMRC actively challenges mixed-use claims, and tribunals look closely at them. In Hyman v HMRC [2022] EWCA Civ 185 the Court of Appeal rejected the buyers' argument that land around their house was not part of its grounds. Taxpayers do sometimes win: in Sehgal v HMRC [2025] UKFTT 1439 (TC) a storage unit bought with a flat was held to be non-residential. A small home office or a garden shed does not make a property mixed-use; the non-residential element must be genuine. Claims that fail can result in the full residential rate plus penalties.
How Stamp Duty Avoidance Schemes Work, and Why HMRC Defeats Them
Marketed schemes usually split a purchase into several steps (sub-sales, company or partnership transfers, options or leases) so that each step attracts less tax than a straightforward purchase. The law has three answers to them:
- Section 75A Finance Act 2003: where a disposal and acquisition of land involve a number of transactions and the total SDLT is less than on a single notional purchase, SDLT is charged as if that notional purchase had happened. There is no motive test. The Court of Appeal applied it in Tower One St George Wharf v HMRC [2025] EWCA Civ 1588.
- Disclosure of tax avoidance schemes (DOTAS): SDLT is one of the taxes covered. Promoters must tell HMRC about a scheme within 5 days of making it available, and HMRC issues a scheme reference number that users must be given, so HMRC knows who used it.
- General anti-abuse rule (GAAR): Part 5 of the Finance Act 2013 applies to SDLT and lets HMRC counteract arrangements that are abusive.
The legitimate ways to pay less are the reliefs and timing choices above. A scheme that promises to cut the tax on an ordinary purchase is very likely to fail, leaving you with the original tax, interest and possibly penalties.
What Counts as Illegal Evasion
The following are not legitimate stamp duty avoidance strategies and can result in criminal prosecution:
- Under-declaring the purchase price: Reporting a lower price to HMRC than what you actually paid
- Side payments: Paying part of the price in cash or through separate agreements to reduce the declared consideration
- False first-time buyer claims: Claiming FTB relief when you or your co-buyer have previously owned property
- Sham trusts or nominees: Using artificial structures with no genuine commercial purpose to reduce the taxable amount
- Fake commercial elements: Claiming mixed-use rates when there is no genuine business activity
HMRC can assess stamp duty for up to 20 years where the loss of tax was deliberate. Inaccuracy penalties are up to 30% of the extra tax for careless errors, 70% for deliberate ones and 100% where they are deliberate and concealed, on top of the tax itself and interest.
Frequently Asked Questions
Can I avoid stamp duty by gifting a property?
If there is no mortgage involved and no money changes hands, a genuine gift between individuals has no SDLT liability (the consideration is £0). However, if a mortgage is transferred as part of the gift, the recipient pays SDLT on the outstanding mortgage amount. See the transfer of equity calculator.
Is it worth buying through a company to avoid stamp duty?
No. Below £500,000 a company pays the standard bands plus the 5% surcharge. Above £500,000 a flat 17% rate applies to the whole purchase price unless a relief applies, such as for a property rental business, which takes it back to the standard bands plus 5%. Company purchase does not reduce SDLT. It may offer other tax advantages (corporation tax rather than income tax on rental profits), but these require professional advice and long-term planning.
Can I avoid stamp duty on a new build?
New builds are subject to standard SDLT rules. Some developers offer stamp duty paid promotions as a sales incentive, which effectively means the developer covers the cost. This does not reduce the tax itself but transfers the financial burden. FTB relief still applies if eligible.
Does stamp duty apply in Scotland and Wales?
Scotland has Land and Buildings Transaction Tax (LBTT) and Wales has Land Transaction Tax (LTT). Many of the same principles apply (additional-property surcharges, refund rules), but rates, thresholds, and reliefs differ. Scotland has its own first-time buyer relief; Wales has none. Each country has its own refund rules and timescales.
Can I claim stamp duty back after buying?
You can claim a refund of the additional property surcharge if you sell your previous main residence within 36 months. You can also amend an SDLT return within 12 months if you overpaid due to an error. See the stamp duty refund guide for all refund scenarios.
