Leasehold Property Tax 2026/27

Ground Rent and Service Charges

Ground rent and service charges are payments made by a leaseholder to the freeholder or management company. For tax purposes, the treatment depends on whether you are the leaseholder (tenant) or the freeholder (landlord). For leaseholders: ground rent and service charges are not generally tax-deductible if the property is your main home. If the property is let out to a tenant, ground rent and service charges are allowable expenses that can be deducted from rental income. For freeholders: ground rent received is rental income and must be declared on the SA105 property pages of your Self Assessment tax return. Ground rent is treated as property income and is taxable at your marginal income tax rate. Service charges collected from leaseholders are not generally taxable as income if they are held on trust for the purpose of maintaining the building — they are treated as a trust fund. However, any surplus in the service charge account at the end of the year may be taxable as property income if it is not returned to leaseholders or held for future expenditure. The tax treatment of ground rent and service charges can be complex, particularly for larger blocks with multiple leaseholders and sinking funds. Professional advice from a chartered accountant with property expertise is recommended for freeholders managing leasehold properties. The Leasehold Reform (Ground Rent) Act 2022 prohibited ground rent on most new residential leases of 1 July 2022 or later, capping ground rent at a peppercorn (nil). This reform means new leaseholders will not have ground rent to pay or deduct, simplifying the tax treatment.

SDLT on Leasehold Purchases

SDLT on leasehold property has two components: the lease premium (the purchase price for the lease) and the net present value (NPV) of the ground rent. SDLT is charged on the lease premium at the same residential rates as freehold purchases. The nil-rate band is £250,000, with rates rising to 12% above £1.5 million. The additional 5% surcharge applies to second homes and buy-to-let purchases. In addition to the premium, SDLT is charged on the NPV of the ground rent at 1% on any amount above £150,000. The NPV is calculated by HMRC using a formula that discounts the future ground rent payments to a present-day value. For leases with low or peppercorn ground rent, the NPV is likely to be below £150,000, meaning no additional SDLT. For leases with high ground rent, the NPV charge can be significant. For example, if a ground rent of £500 per year is payable on a 99-year lease, the NPV will be well above £150,000, generating an additional SDLT charge. The NPV calculation is complex and must be done using HMRC's approved formula. Your solicitor or conveyancer will calculate the SDLT due on both the premium and the ground rent. First-time buyer relief applies to leasehold purchases, covering both the premium and the ground rent element, provided the total purchase price is within the first-time buyer limits (£425,000 for relief, up to £625,000 for reduced rates).

Lease Extensions

When you extend a lease, you typically pay a premium (lump sum) to the freeholder. The tax treatment of lease extension costs depends on the purpose of the extension. For owner-occupiers: the cost of extending your residential lease is not deductible for income tax purposes. However, it can be added to the cost base for Capital Gains Tax purposes when you sell the leasehold interest, reducing your CGT liability. The cost of the extension (including legal and valuation fees) is treated as enhancement expenditure. For landlords (investors): the cost of extending a lease on a rental property is capital expenditure and is not deductible against rental income. It should be added to the cost base for CGT purposes when you sell the property. If the lease extension is for a short lease (under 50 years remaining), the CGT calculation on disposal becomes more complex due to the wasting asset rules. The cost of the extension can reduce the gain but the interaction with the wasting asset rules requires careful computation. The Leasehold Reform, Housing and Urban Development Act 1993 gives leaseholders the right to extend their lease by 90 years (for flats) or 50 years (for houses), with the ground rent reduced to a peppercorn. The cost of exercising this statutory right is treated as capital expenditure for tax purposes. If you are extending a lease on a property you let out, the cost is not an allowable expense against rental income but can reduce CGT on eventual disposal.

Enfranchisement (Buying the Freehold)

Enfranchisement is the process by which leaseholders collectively buy the freehold of their building. The cost of acquiring the freehold is capital expenditure and is not deductible against rental income. Instead, it forms part of the cost base for CGT purposes when you sell the leasehold interest (or the freehold if you have merged the leasehold and freehold interests). SDLT is payable on the enfranchisement premium if it exceeds the SDLT threshold. The 5% additional SDLT surcharge may apply if the purchase is of an additional residential property for investment purposes. If you are an owner-occupier buying the freehold of your own flat, the freehold interest is treated as part of your main residence and is covered by Principal Private Residence Relief when you sell. When you sell a property following enfranchisement, the CGT calculations can be complex because you have merged two separate interests (the leasehold and the freehold) with different acquisition dates and costs. Professional valuation advice is essential to apportion the costs correctly between the leasehold and freehold interests and to calculate the gain accurately on disposal. The enfranchisement process is governed by the Leasehold Reform, Housing and Urban Development Act 1993 and requires a formal valuation by a qualified surveyor. The legal costs of enfranchisement are also capital expenditure and can be added to the cost base for CGT purposes.

Tax Treatment of Premiums

Lease premiums — payments made by a tenant to a landlord for the grant of a lease — have specific tax treatment for both parties. For the landlord (freeholder): a lease premium received is treated as property income and is taxable as part of the landlord's rental business. However, for leases granted for 50 years or less, part of the premium is treated as income (taxable in the year of receipt) and part as capital (potentially subject to CGT on disposal of the freehold). The income element is calculated using the formula: P × (50 - Y) ÷ 50, where P is the premium and Y is the number of complete years of the lease (excluding the first year). This rule prevents landlords from converting income into capital gains by taking large premiums instead of high rent. For the tenant (leaseholder): a lease premium paid is capital expenditure and can be added to the cost base for CGT when the lease is disposed of. However, if the premium relates to a short lease (under 50 years), the tenant may be able to claim a deduction against rental income for the part of the premium that the landlord pays income tax on. This is known as the lease premium deduction and is available to tenants who use the property for business purposes (including letting). The deduction is spread over the term of the lease. The tax treatment of lease premiums is complex and professional advice is strongly recommended for both landlords and tenants involved in granting or taking leases.

Leasehold Reforms 2026/27

The Leasehold Reform (Ground Rent) Act 2022 has significantly changed the landscape for new residential leases. Ground rent on most new long residential leases is now set at a peppercorn (nil), simplifying the tax treatment for both leaseholders and freeholders. The government has also committed to further leasehold reforms, including: banning the sale of new leasehold houses (except in exceptional circumstances), restricting ground rent on existing leases, making it easier and cheaper for leaseholders to extend their leases or buy the freehold, and increasing the standard lease extension term to 990 years for both flats and houses. These reforms will affect the tax treatment of leasehold property, particularly the income tax treatment of ground rent for freeholders and the CGT treatment of lease extensions and enfranchisement. Leaseholders considering extending their lease or buying their freehold should act sooner rather than later, as the costs of statutory lease extensions may increase under the new regime. The reforms are being phased in, and the full implementation is expected by 2027. Professional advice is essential to navigate the current transitional arrangements and to understand the impact of the reforms on your specific circumstances.
