Stamp Duty & Commercial Leases

When entering into a commercial lease, tenants and landlords often overlook Stamp Duty Land Tax (SDLT) until the bill arrives. It’s a tax due to HM Revenue & Customs (HMRC) on both the upfront premium and the net present value (NPV) of rent. Understanding how SDLT applies ensures you plan effectively and avoid surprises!

In this article, we will explain what SDLT is, when it applies to commercial leases, how it’s calculated and what steps you should take to be compliant.

Stamp Duty Land Tax is a tax payable on property transactions. In the context of commercial property, SDLT applies to two key elements:

• Premium – a lump-sum payment made to secure the lease.
• Net Present Value (NPV) of rent – the total value of future rent payments, discounted to present-day value.

SDLT becomes payable on commercial leases when either:

• A premium is paid that exceeds £150,000, or
• The NPV of rent over the lease term exceeds £150,000.

Even if no tax is payable, a return might still be necessary if lease terms exceed 7 years and meet the threshold conditions, including if either of the above amounts to more than £40,000.

1. Premium

The SDLT rates for premiums on commercial leases mirror non-residential property rates:

• Up to £150,000 – 0%
• £150,001 to £250,000 – 2%
• Over £250,000 – 5%

2. Net Present Value (NPV) of Rent

Rent SDLT is calculated on the NPV of rent payments:

• Up to £150,000 – 0%
• £150,001 to £5 million – 1%
• Over £5 million – 2%

You must submit the SDLT return and pay any tax due to HMRC within 14 days of the lease’s effective date—usually the completion date. It is important to note that should you choose to backdate your lease, the SDLT may be payable from that date. Should you pay SDLT late, fees and interest are payable based on the rent and how late the SDLT submission is made. Even if no tax is payable, a return is still necessary for leases of 7 years or more exceeding thresholds.

Lease renewals generally count as a new lease for SDLT purposes. Extensions or rent increases may also trigger additional SDLT liability. It is important to obtain advice before proceeding with any conveyancing matters to understand your SDLT obligations and the consequences of your transaction.
