The old £2 million SDLT threshold for company home purchases
The short answer
The £2 million threshold can survive for some old company-home contracts made before 20 March 2014. Later changes to the deal can stop that result.
- Check the contract date and substantial-performance date.
- Check for later variations, assignments, options and sub-sales.
- Partnership cases have a separate historic-date rule.

The old £2 million SDLT threshold for company home purchases

The old £2 million SDLT threshold for company home purchases
A company that bought a home under an old contract may fall within a £2 million threshold rather than £500,000. This narrow rule transitional rule dates from 2014. A later change to the deal can remove it and may make a major difference to stamp duty.
What this rule is about
On 20 March 2014, Finance Act 2014 cut the threshold for a special SDLT charge on certain company and similar buyers of homes from £2 million to £500,000.
Parliament did not apply the change to every case involving an old contract. It kept the £2 million threshold for some arrangements already in place. Rather than asking when completion occurred, you should ask what happened to the contract before and after 20 March 2014.
This is an historic rule. It matters only if old arrangements still underpin the transaction.
What the official source says
HMRC’s manual says the older £2 million threshold remains where parties entered into and substantially performed a contract before 20 March 2014. It can also remain if the parties entered into the contract before that date, even if they had not then substantially performed it.
That second route has important limits. Any of the following events on or after 20 March 2014 removes the £2 million threshold:
- the contract was varied in any way
- rights under the contract were assigned to someone else
- the deal followed the exercise of an option, pre-emption right or similar right
- there was an assignment, sub-sale or similar transaction involving all or part of the property
- as a result, someone other than the original buyer could require the property to be transferred to them
In this context, substantial performance has a specific legal meaning. It can occur before formal completion if the buyer takes possession of most or all of the property, or pays most or all of the amount due.
The manual also identifies a separate rule for certain partnership arrangements. A deemed land transaction following a transfer of a partnership interest, or a withdrawal from a partnership, keeps the £2 million threshold if the partnership’s own purchase had an effective date before 20 March 2014.
What this means in practice
You cannot safely decide this issue by looking only at the completion date. An old contract may preserve the higher threshold. However, a later document that seemed routine at the time may move the result to the £500,000 threshold.
This is the point people can miss: the rule looks for any relevant later step, rather than only a wholesale replacement of the contract.
- Keep the original signed contract, not just the transfer deed.
- Check whether anyone changed the terms after 20 March 2014.
- Check whether a different person gained a right to call for the transfer.
- Review options, nomination arrangements and sub-sale paperwork.
- For partnerships, identify the date of the partnership’s own purchase first.
How to analyse it
Begin with the documents and dates. Labels do not settle the issue. For example, describing a document as an administrative change does not answer whether it varied the contract or moved rights under it.
- Is this a purchase that otherwise falls within the special rules for a company or similar buyer?
- What amount is attributable to the home?
- Was the contract entered into before 20 March 2014?
- Was it substantially performed before that date?
- If not, was it varied on or after that date?
- Did rights under it move to another person?
- Did an option, pre-emption right or similar right lead to the purchase?
- Did a sub-sale or other step let someone else require the transfer?
- If a partnership is involved, what was the effective date of its earlier land purchase?
Decide which threshold applies only after answering those questions. The threshold question remains separate from other conditions and any relief that may affect the wider SDLT result.
Example
Assume a company agreed to buy one home for £1.4 million on 1 March 2014. The company completed the contract later. Nothing was changed, assigned or passed to another buyer on or after 20 March. On the facts stated, HMRC’s manual says the old £2 million threshold remains relevant. The £1.4 million price is below that threshold.
Now change one fact. If the parties varied that contract on 21 March 2014, the manual says the old threshold is not retained. The £500,000 threshold would then be the relevant one. The example does not decide the final SDLT bill. It shows why the later variation matters.
Why this can be difficult in practice
Old property deals can involve many papers: side letters, deeds of variation, nominations and funding changes. Their titles may not make their effect obvious. Timing also matters, particularly where possession or large payments came before completion.
- A formal completion after 20 March 2014 does not by itself settle the answer.
- Taking possession or making a large payment may mean the contract was substantially performed earlier.
- A later change that seems minor may still be a variation under the transition rule.
- A partnership event needs separate analysis under the partnership provisions.
- HMRC’s manual describes its view, but it is not itself the legislation.
Key takeaways
- The £2 million threshold survives only for defined pre-20 March 2014 arrangements.
- Later changes to the contract can remove that historic protection.
- Check the full paper trail, including partnership records where relevant.

Legislation
- an Act of 2014 we do not have an identifier for section 111 — cuts the company-home threshold to £500,000 (no link: an Act of 2014 we do not have an identifier for)
- FA 2003 Schedule 4A para 1 — defines a high-threshold interest in one home
- FA 2003 section 44 — explains when a contract is substantially performed

Official guidance
The pages below are HMRC’s guidance. Guidance is not law. It sets out how HMRC reads the legislation, and it is not binding on you, on a tribunal or on a court. Where guidance and the legislation differ, the legislation wins. HMRC can also change or withdraw guidance, and it may not cover your facts.
Where this is not settled
- Whether a later document is a variation, an assignment, a sub-sale or a similar transaction can depend on its legal effect and the full transaction documents.
- For a partnership case, the relevant event and the effective date of the partnership’s earlier purchase must be established from the facts.
Evidence you would need
This kind of case is decided on the facts of the individual property. These are the records that usually settle it, and the ones an adviser would ask you for.
- The signed contract and its date.
- Completion, possession and payment records showing whether and when the contract was substantially performed.
- Any later variation, assignment, option, pre-emption agreement, nomination or sub-sale document.
- For a partnership case, records of the partnership’s original land purchase and later changes in partnership interests or withdrawals.
