About UK stamp duty (SDLT)

How UK Stamp Duty Land Tax (SDLT) is calculated

Progressive rate on purchase price

SDLT rates, first-time-buyer relief, and the additional-dwelling surcharge are all set by HMRC. Source: GOV.UK — Stamp Duty Land Tax.

SDLT is calculated on a progressive scale — you pay each rate only on the portion of the price within that band. For a £400,000 purchase (standard): 0% on £0–£125,000 = £0; 2% on £125,001–£250,000 = £2,500; 5% on £250,001–£400,000 = £7,500. Total SDLT = £10,000.

Payable within 14 days

SDLT must be paid within 14 days of completing the purchase (30 days for non-residential). Your solicitor typically files the SDLT1 return and arranges payment as part of the conveyancing process. SDLT cannot be added to your mortgage — it must be paid from cash/savings.

First-time buyer relief is lost entirely if purchase price exceeds £500,000.

How first-time buyer relief reduces Stamp Duty Land Tax

0% up to £300,000

First-time buyers pay no SDLT on the first £300,000 of a residential property purchase. On the portion between £300,001 and £500,000, 5% applies. Above £500,000, standard rates apply with no relief.

Qualifying conditions

All purchasers must be first-time buyers (never owned a residential property in the UK or abroad). The property must be your main residence. You must be an individual buyer — companies cannot claim first-time buyer relief. HMRC validates claims against property records.

When the 5% SDLT surcharge applies to additional property purchases

5% on top of all standard bands

When you purchase an additional residential property (buy-to-let, holiday home, second home), a 5% surcharge applies across all SDLT bands (raised from 3% on 31 October 2024). On a £350,000 second property, SDLT is £25,000 vs £7,500 for a standard purchase — an extra £17,500.

Reclaiming if you sell your main home

If you paid the additional dwelling surcharge but then sold your previous main residence within 3 years of the new purchase, you can apply to HMRC for a refund. The refund window is 12 months from the sale date (or from the 3-year anniversary).

UK Stamp Duty reliefs and exemptions 2026-27

First-time buyer relief

No SDLT on properties up to £300,000. Reduced 5% rate £300k-£500k. No relief above £500k. Both buyers must be first-time buyers. Includes purchases as trustee for minor.

Non-residential and mixed-use rates

Commercial/mixed-use: 0% up to £150,000, 2% to £250,000, 5% above. No 5% investor surcharge. Useful for flats above shops.

Multiple dwellings relief

Mostly abolished June 2024 but still for buying 6+ properties in single transaction — calculated per-property.

Refund of 5% surcharge

If buying new main home before selling old, pay 5% surcharge, claim refund within 36 months of completion. HMRC 3-year rule.

Right to Buy SDLT

Council tenants pay SDLT on the discounted price, not market value. Substantial saving for larger RTB discounts.

Charities and registered social landlords

Full SDLT exemption on property acquisitions. Similar reliefs for pension schemes and certain housing associations.

How to pay UK Stamp Duty — process and deadlines

14-day payment deadline

SDLT return and payment due within 14 days of completion. Your solicitor handles via conveyancing. Late: £100 penalty, then £200 after 3 months, plus interest.

The SDLT1 return

Online form submitted by solicitor. Includes property, buyers, reliefs claimed. You receive SDLT5 certificate as proof of payment — needed for Land Registry.

Common mistakes to avoid

Missing FTB relief. Over-apportioning to fittings/chattels (anti-avoidance rules). Forgetting linked transactions. Second-home surcharge: applies to ANY additional residential property, including inherited or overseas properties.

Overpaid SDLT refunds

Amend SDLT return within 12 months. Common refund scenarios: FTB relief missed, multiple dwellings relief, separated couple relief. Professional review worthwhile if refund could exceed £2,000.

Who qualifies as first-time buyer

Never previously owned a residential property anywhere in the world. Both buyers must qualify if buying jointly. Inheritance of a share counts as ownership — check carefully. Includes previous buy-to-let ownership. Trust arrangements also count as prior ownership.

Common FTB relief mistakes

Partner previously owned — loses relief for both. Buying with parents not on deed — can claim if only FTBs on deeds. Previous overseas ownership — yes, counts as prior ownership. Prior inherited share under £40k — may still disqualify, get advice.

Shared ownership and FTB relief

Can claim FTB relief on shared ownership. Two options: pay SDLT on full market value upfront (preserves FTB relief forever) or pay SDLT only on initial share (pay more on future staircasing). Choose wisely — can't change later.

UK second home and buy-to-let SDLT surcharge

5% additional SDLT surcharge (from October 2024)

5% additional SDLT on any additional residential property worth £40,000+. Was 3% before October 2024 — doubled under Budget changes. Applies on top of standard SDLT rates.

When surcharge applies

Second homes, buy-to-let, holiday homes, any property acquired while already owning residential property. Property must be worth £40,000+ to trigger. Properties in UK or overseas count — inherited share abroad can trigger surcharge.

Moving main home — 5% refund rule

Buying new main home before selling old: pay 5% surcharge upfront. Sell old home within 3 years: claim refund of surcharge from HMRC. Within 12 months of sale of old home. 36-month window exists in exceptional circumstances.

Limited company SDLT — no surcharge exemption

Companies buying residential property pay surcharge on first property. Plus 15% flat rate if property over £500,000 unless used for qualifying property business. SPV structures popular despite surcharge due to other tax efficiencies.

UK Stamp Duty history and recent changes

Recent SDLT changes

DateChange
April 2025FTB threshold reverted to £300k (from temporary £425k); nil-rate band reverted to £125k (from £250k)
October 2024Second home surcharge raised to 5% (from 3%)
September 2022Nil rate band temporarily raised to £250k (expired April 2025)
July 2020COVID stamp duty holiday — nil to £500k
April 20163% surcharge introduced on additional homes
December 2014Slab system replaced with progressive bands
1997Modern SDLT (then Stamp Duty) regime established

Historical rates comparison

Pre-2014: slab system charged percentage on entire value. £251k home at 1% = £2,510, but £250k at 1% = £2,500 — creating distortion. Progressive system fixed this — each band only charges its rate on the portion within it.

Current outlook

Government has indicated SDLT thresholds will be reviewed periodically. Potential future changes: further rise in second home surcharge; possible FTB threshold cuts. Labour government has committed to maintaining current structure through 2026-27.

UK Stamp Duty on commercial and mixed-use property

Non-residential/mixed-use SDLT rates

PortionRate
Up to £150,0000%
£150,001 - £250,0002%
Above £250,0005%

No 5% surcharge on commercial

Commercial property (shops, offices, warehouses) uses these lower rates without the 5% additional surcharge. Mixed-use (flat above shop) can qualify too. Significant saving vs residential purchase — £500k shop = £17,500 SDLT vs £40,000 for second home.

When property qualifies as mixed-use

Must have commercial element — flat above operational shop. Not: large garden, paddock. HMRC guidance has tightened — treating properties as mixed-use aggressively has been challenged in tribunal. Get tax advice before claiming mixed-use.

SDLT on leases

Lease premium taxed like purchase (above £150k). Plus 1% on net present value of rents above £150k threshold. Long leases can create significant SDLT charges. SDLT on rent reviews too.

UK Stamp Duty scenarios: divorce, inherited property, gifts

Transfer between spouses/civil partners

Transfers between spouses: usually no SDLT. Divorce transfers under court order: exempt. Cohabiting couples not exempt — standard SDLT applies to property transfers.

Inheriting a property

No SDLT on inherited property (no chargeable consideration). But inheriting a share can trigger 5% surcharge on future purchases — as you become a 'second home' owner. Keep or sell inheritance before next purchase to avoid surcharge.

Gifted property

Outright gifts (no mortgage): usually no SDLT. If mortgage transferred: SDLT due on outstanding mortgage amount. Gifts to children: watch potential Gifts With Reservation rules and 7-year IHT rule.

SDLT on divorce

Court-ordered transfers: exempt from SDLT even if outside standard spouse exemption. Voluntary transfers before divorce: need careful timing. Post-separation but pre-court order: SDLT may apply.

Second home you're forced to buy

Relocation for work, divorce — you may temporarily own two properties. 5% surcharge applies upfront. Claim refund within 36 months when old home sold. HMRC extended period to 3 years for exceptional circumstances (e.g. market frozen).

Property bought in joint names

All buyers must qualify for FTB relief, or relief lost entirely. Only one buyer previously owned? Lose FTB relief and pay standard rates on full purchase. Joint purchases with non-FTB partners very common mistake.

UK Stamp Duty planning strategies

Buy before selling — surcharge refund strategy

Buy new main home first, pay 5% surcharge. Sell old home within 36 months: full refund of surcharge from HMRC. Popular in tight markets where you can't coordinate chain timing.

Transfer shares instead of property

Company owning property: selling shares vs selling property. Share sale may avoid SDLT. But company gains subject to corporation tax. Complex but can be tax-efficient for investors at scale.

Mixed-use classification

Properties with commercial element use lower non-residential rates. £1m purely residential: £43,750 SDLT. Same at £1m mixed-use: £39,500 SDLT. HMRC has challenged aggressive mixed-use claims — get professional advice.

Multiple dwellings relief (limited post-2024)

Before June 2024: buy multiple dwellings in one transaction, calculate SDLT per-dwelling rather than aggregated. Now only for 6+ dwelling transactions. Saves thousands on qualifying purchases.

Timing purchase with tax year

SDLT based on completion date. Budget announcements sometimes change rates mid-year. Monitor announcements — early completion can save surcharges or benefit from thresholds.

First-time buyer partner strategy

Non-FTB partner buying solo preserves other partner's FTB status for future separate purchase. Less common but valid planning if one partner will likely buy separately later.

UK Stamp Duty for overseas buyers and non-residents

2% non-resident surcharge

Additional 2% SDLT on residential property purchases by non-UK residents (from April 2021). On top of any other rates (FTB, 5% second home). Applies to individuals spending fewer than 183 days in UK in 12 months before purchase.

£2,000,000£153,750£193,750£293,750

UK residents returning from abroad

UK residents returning after long-term non-residency: treated as non-resident for SDLT in first 12 months. After 12 months of UK residency, normal rates apply. Plan timing carefully for significant purchases.

Refund of non-resident surcharge

If you become UK resident (183+ days) within 12 months of purchase: can claim refund of 2% surcharge. Must apply within 2 years. Useful for those relocating permanently to UK.

Company purchases of UK property

Offshore companies: Annual Tax on Enveloped Dwellings (ATED). Properties over £500,000 owned by companies: £4,150 to £287,500 annual charge (2024-25). Plus 15% flat SDLT on purchase if over £500k unless qualifying business.

Frequently asked questions about UK Stamp Duty

How much is stamp duty on a £350,000 house?

Standard: 0% on first £125k, 2% on £125k-£250k (£2,500), 5% on £250k-£350k (£5,000) = £7,500. First-time buyer: £2,500 (0% to £300k, 5% on £300k-£350k). Additional property: £7,500 + 5% surcharge (£17,500) = £25,000.

When does stamp duty need to be paid?

SDLT must be paid and the SDLT1 return filed within 14 days of completing the purchase. Your solicitor typically handles this as part of conveyancing. Late filing incurs penalties: £100 after 14 days, £200 after 3 months, plus interest and potentially further penalties.

Does stamp duty apply in Scotland and Wales?

No — Scotland uses Land and Buildings Transaction Tax (LBTT) with different rates and thresholds, administered by Revenue Scotland. Wales uses Land Transaction Tax (LTT) with its own rates, administered by the Welsh Revenue Authority. This calculator covers England and Northern Ireland (SDLT) only.

Can stamp duty be added to my mortgage?

No. SDLT must be paid in cash — it cannot be added to your mortgage. Some buyers use a short-term loan or gifted funds from family, but SDLT must be paid from funds available at completion. Factor SDLT into your total purchase budget alongside legal fees, surveys, and moving costs.

Where these figures come from

Property and mortgage figures on this page are drawn from HMRC (Stamp Duty Land Tax), The Bank of England (mortgage-rate data), The FCA (mortgage conduct rules), and HM Land Registry (house-price data).

Last checked: April 2026. Rates and thresholds are reviewed against the source of record each November, when annual adjustments for the following tax year are published.

Understanding your result

Select the question that matches where you are right now.

Your result reflects the financial position of the property scenario you entered — based on current rates, market rules, and standard calculation methods used across the Australian property industry.

What to do with it

Use this as a planning figure. Compare different property prices, deposit sizes, or loan terms to see how each changes the outcome. Adjust inputs in Standard or Advanced mode for more detail.

What it is not

Not a bank approval, valuation, or guarantee. Lenders apply their own policies, credit checks, and property assessments beyond what any calculator can model.

Accuracy

Calculations use current published rates and standard formulas. All processing runs in your browser — no data is sent to any server.

Property calculations are most sensitive to the interest rate, loan amount, and time horizon. Small changes to these inputs produce the largest shifts in your result.

Interest rate

A 0.5% rate change on a £500k loan shifts annual interest by ~£2,500. Use Standard mode to compare fixed vs variable rate scenarios.

Loan term and structure

Extending the loan term reduces repayments but increases total interest. Interest-only periods change cash flow but not total cost. Model both in Advanced mode.

Property value and LVR

The ratio of your loan to the property value affects LMI, rate pricing, and lender appetite. Crossing the 80% LVR threshold changes the cost structure significantly.

To improve your property outcome, focus on the inputs with the highest leverage — these typically produce more impact per dollar than broad changes.

Increase your deposit

A larger deposit reduces LVR, eliminates LMI at 80%, and may unlock better rate pricing. Even £10k–£20k extra deposit can shift the cost picture.

Reduce existing debts

Credit card limits and personal loans reduce borrowing capacity pound-for-pound. Closing unused cards before applying is one of the fastest levers.

Compare across lenders

Rate, policy, and LVR treatment vary between lenders. A mortgage broker can identify the best fit for your specific profile and property type.

Property decisions involve multiple linked calculations. Use the related calculators to model the full picture before committing.
