Stamp Duty Land Tax Calculation for Successive 3-Year Leases Example

SDLT treatment of successive linked leases

When linked leases follow one another between the same parties, SDLT may treat them as one single lease rather than separate leases. This commonly applies where an original lease includes a right to renew and a further lease is granted on expiry on the same terms, which can increase SDLT because the tax on rent is based on the combined term and rent.

• If the statutory rule on successive leases applies, SDLT is calculated as if one lease had been granted at the start of the first lease.
• The deemed lease uses the first lease date, the total combined term and the rent payable across the series.
• In the example given, a 3-year lease from 1 January 2004 renewed for another 3 years is treated for SDLT as one 6-year lease from 1 January 2004 at £50,000 a year.
• This does not change the property law position of the later lease; it only changes the SDLT calculation.
• You should check whether the leases are between the same parties, cover the same property and form a continuing series, especially where there is a renewal right.
• Borderline cases can be harder where terms, rent, parties or timing differ, so the exact wording of Schedule 17A paragraph 5 and the facts will matter.

SDLT and successive linked leases: when renewal leases are treated as one lease

This page explains a specific SDLT rule for leases that follow each other between the same parties. In some cases, what looks like a new lease is not treated separately for SDLT. Instead, the leases are treated as a single lease running from the start of the first one. That matters because SDLT on rent depends heavily on the total term and the total rent profile.

What this rule is about

The rule deals with successive leases. These are leases that come one after another and are linked in the way described by Schedule 17A to Finance Act 2003. The example in the official material concerns a lease that includes a right to renew, followed by a new lease on the same terms between the same parties.

The legal effect is important. If the leases are successive within the legislation, SDLT is not worked out by looking at each lease in isolation. Instead, the series is treated as if it were one lease granted at the beginning of the first lease.

This can increase the SDLT position compared with looking only at the later lease by itself, because the notional single lease has a longer total term.

What the official source says

The official example says:

• a 3-year lease is granted on 1 January 2004 at a rent of £50,000 a year;
• the lease includes a right to renew on expiry at the same rent;
• on 1 January 2007, a new 3-year lease is granted between the same parties on the same terms.

Under paragraph 5 of Schedule 17A to Finance Act 2003, the two leases are treated as successive leases. SDLT is then calculated as though there were a single lease:

• granted on 1 January 2004, being the date of the first lease;
• for a 6-year term, being the combined length of both leases; and
• at a rent of £50,000 a year, reflecting the rent payable under the leases in the series.

The source is giving a worked example of the statutory fiction created by the legislation. It is not saying that the second lease disappears in property law terms. It is saying that, for SDLT purposes, the series is taxed as one lease.

What this means in practice

If a lease contains a right to renew and that right is exercised through a new lease on expiry, you should not assume the new lease is taxed as a completely separate transaction. The legislation may require you to combine the leases and recalculate SDLT as though there had been one longer lease from the outset.

In practice, that means you need to focus on three things:

• when the first lease in the series began;
• the total length of all leases in the series; and
• the rent payable across the series.

For lease transactions, SDLT on rent is based on the lease term and rent figures. A longer deemed term can change the SDLT result. So this rule is not just technical drafting. It can alter the tax calculation materially.

The example also shows that the same parties and the same terms matter. The official material uses a renewal lease granted between the same parties on the same rent and terms. That is the factual pattern the example is illustrating.

How to analyse it

A sensible way to approach this issue is to ask the following questions:

• Is there an earlier lease and a later lease of the same property or substantially the same subject matter?
• Does the earlier lease include a right to renew, or is there some other reason the leases may fall within the statutory rule on successive leases?
• Are the leases between the same parties, as in the official example?
• Does the later lease begin when the earlier one ends, or otherwise form part of a continuing series?
• If they are successive leases under the legislation, what is the aggregate term of the whole series?
• What rent is payable under the leases in the series for SDLT purposes?

Once you conclude that the rule applies, the SDLT analysis is carried out on the notional single lease rather than on each lease separately. The deemed lease starts on the date of the first lease and runs for the combined term.

That is the key shift in analysis. The question is no longer “what is the SDLT on the second lease?” but “what is the SDLT position if both leases are treated as one lease from the start?”

Example

Illustration: a tenant takes a 3-year lease from 1 January 2004 at £50,000 a year. The lease gives the tenant the right to renew at the same rent when it ends. On 1 January 2007, the landlord grants a further 3-year lease to the same tenant on the same terms.

Under the official example, these are successive leases. So for SDLT, you do not treat the 2007 lease as a fresh standalone 3-year lease. Instead, you treat the arrangement as if one 6-year lease had been granted on 1 January 2004 at £50,000 a year.

The practical consequence is that the SDLT calculation must be based on that deemed 6-year lease.

Why this can be difficult in practice

The official example is short and clear on its facts, but real transactions are often less neat.

Difficulties can arise where:

• the later lease is not on exactly the same terms;
• the parties have changed;
• the rent changes on renewal;
• there is a gap between leases;
• it is unclear whether the later lease is truly a renewal contemplated by the earlier lease, or simply a new bargain.

The source material here does not explore those variations. So while the example clearly demonstrates the principle, it does not answer every borderline case. In those situations, the exact wording of Schedule 17A paragraph 5 and the facts of the lease arrangements will matter.

Another practical difficulty is procedural. Where a later lease causes the earlier and later leases to be treated as one notional lease, the SDLT position may need to be revisited by reference to the first grant date and the aggregate term. The source example does not set out the filing or amendment mechanics, so it should not be read as doing so.

Key takeaways

• A renewal lease can be treated with the original lease as one lease for SDLT purposes if the statutory rule on successive leases applies.
• The deemed single lease starts on the date of the first lease and runs for the combined term of the leases in the series.
• Do not assume a later renewal lease is taxed in isolation; the SDLT calculation may need to be based on the whole series.
