SDLT on Leasehold Premiums: Rates, Surcharges and Reliefs

SDLT on leasehold premiums is charged on the lump sum you pay the landlord when a lease is granted or assigned, using the same progressive band structure as freehold purchases. For residential leases the tax-free slice runs up to £125,000; for non-residential and mixed-use leases it runs up to £150,000. Rent under the lease is taxed separately through a net present value calculation, so a leasehold transaction can produce two SDLT charges.

Residential Premium Rates

Each slice of the premium is taxed at its own rate:

Up to £125,000: 0%
£125,001 to £250,000: 2%
£250,001 to £925,000: 5%
£925,001 to £1.5 million: 10%
Above £1.5 million: 12%

On a £300,000 premium you pay nothing on the first £125,000, 2% on the next £125,000 (£2,500), and 5% on the remaining £50,000 (£2,500). Total: £5,000.¹

Non-Residential and Mixed-Use Premium Rates

Commercial and mixed-use premiums use lower rates and a bigger tax-free band:

Up to £150,000: 0%
£150,001 to £250,000: 2%
Above £250,000: 5%

Any lease that is not purely residential falls under these bands, including a property with both commercial and residential elements.²

The 5% Surcharge on Additional Residential Properties

If you already own a residential property anywhere in the world and buy another residential leasehold, a 5% surcharge sits on top of every band. The starting slice becomes 5%, the next becomes 7%, and so on. It applies when the new property costs £40,000 or more and you have not sold your previous main home.³

The impact is large. A £400,000 leasehold premium that would attract £7,500 in standard SDLT costs £27,500 with the surcharge. Many buyers hit this because they intend to sell their existing home but have not completed the sale by the time the new purchase completes.

Refund If You Sell Your Old Home

You can reclaim the 5% surcharge if you sell your previous main residence within three years of buying the new property. The refund claim must reach HMRC by the later of: 12 months after the sale date, or 12 months after the SDLT filing date for the new purchase. HMRC reads “exceptional circumstances” narrowly where the three-year window has passed; a slow market at your asking price is not enough.⁴

Non-UK Resident Surcharge

Non-UK residents pay a further 2% on residential leasehold premiums of £40,000 or more. It stacks on both the standard rates and the additional-property surcharge, so a non-resident second-home buyer pays 7% on the first slice alone.⁵

Residence is measured by days in the UK. You count as UK-resident if you spend at least 183 days here during any continuous 365-day period within a window running from 364 days before to 365 days after the transaction date. Because the SDLT return is due within 14 days of completion, you will not usually have hit 183 days by the filing deadline. File as non-resident, and if you later meet the threshold, amend the return and reclaim the 2%.⁶

SDLT on the Rent as Well as the Premium

If the lease reserves more than nominal rent, SDLT is charged on the rent separately from the premium. The rent charge is calculated on the net present value (NPV), which discounts the rent payable across the full lease term back to a present-day figure.⁷

For residential leases, rent SDLT only applies if the NPV exceeds £125,000, and then at 1% on the excess. Most residential ground rents sit well below that, so many flat buyers owe nothing on the rent side.¹ For non-residential leases the NPV threshold is £150,000, with 1% on the slice from £150,001 to £5 million and 2% above that.

Uncertain rent, such as turnover rent, is estimated for the return and recalculated once the actual figures are known or after the first five years. If the recalculated NPV is higher, you must tell HMRC and pay the additional tax within 30 days.⁷

Reliefs That Cut the Premium Charge

First-Time Buyer Relief

If you have never owned property before and are buying a leasehold to live in as your main home, first-time buyer relief gives you 0% on the first £300,000 of the premium and 5% on the slice from £300,001 to £500,000. Above a £500,000 premium the relief falls away entirely and standard rates apply to the whole amount.¹

Every buyer named on the purchase must qualify individually. If one buyer has previously owned property, neither can claim.

Shared Ownership

Buying through an approved shared ownership scheme lets you choose between two SDLT approaches. A market value election charges SDLT once, based on the full market value of the property. The alternative is to pay SDLT only on the premium for your initial share and then pay again as you staircase into larger shares.⁸

The election is permanent once the return is filed. Staged payment costs less upfront but each staircasing step can produce its own SDLT charge. The market value election often makes sense where the full value falls inside first-time buyer relief bands, because you pay once and never revisit.

Multiple Dwellings Relief Has Gone

Multiple Dwellings Relief, which cut SDLT on transactions involving more than one dwelling, was abolished on 1 June 2024. Buyers who exchanged contracts on or before 6 March 2024 and have not varied the contract since are protected by a transitional rule, but no new claims are possible.⁹

Assignments and Lease Extensions

Buying an existing lease from the current tenant is an assignment. Any capital sum you pay is subject to SDLT at the same rates as a premium. HMRC treats some assignments as if they were the grant of a new lease, which means you could also owe SDLT on the NPV of the remaining rent.¹⁰

When a landlord surrenders your existing lease and grants a new, longer one, the premium is taxed in the normal way. Because the new lease overlaps the remaining term of the old one, rent could be taxed twice. Overlap relief prevents that by reducing the rent used in the NPV calculation for the overlapping period by the amount already taxed under the old lease.¹¹

Overlap relief only applies if the old lease was itself subject to SDLT. Leases that predate SDLT’s introduction on 1 December 2003 fell under the old stamp duty regime, and for those no overlap relief is available; the full rent under the new lease goes into the NPV calculation.¹¹

Filing and Payment Deadlines

The SDLT return and the payment are both due within 14 days of the effective date, which is normally completion. File through the HMRC online portal or on paper.¹²

HMRC accepts online banking, debit or corporate credit card, CHAPS, Faster Payments, Bacs, and cheque. CHAPS and Faster Payments arrive same or next working day; Bacs and cheques take three working days. Card payments are treated as received on the date made, including weekends.¹³

Once the return and payment are processed, HMRC issues an SDLT5 certificate. HM Land Registry will not register your leasehold interest without it, so a late filing does more than trigger penalties. It can hold up the whole transaction.¹⁴

Penalties and Interest for Getting It Wrong

Missing the 14-day deadline triggers an automatic £100 penalty. After three months outstanding it rises to £200. Returns more than 12 months late can attract a tax-based penalty of up to 100% of the SDLT due.¹²

Inaccuracy penalties run separately. A careless error is between 0% and 30% of the extra tax that should have been paid. A deliberate error is 20% to 70%, and a deliberate error that is then concealed is 30% to 100%. Voluntary disclosure and cooperation bring the penalty down.¹⁵

Late payment interest runs on top of penalties. The rate is currently 7.75%, set at the Bank of England base rate plus 4%, and runs from the date payment was due, not from any reminder. On a large premium, a short delay adds up quickly.¹⁶
