Understanding Joint and Several Liability in Ordinary Partnership Transactions

SDLT partnership liability: joint and several responsibility

For ordinary partnerships, certain partners treated as responsible for SDLT obligations can be jointly and severally liable. This means HMRC may recover the full amount from any one of those partners, rather than only that person’s share. A key exception applies to partners who joined after the transaction’s effective date, unless a later default after they joined caused the penalty or interest.

• The rule covers SDLT, interest on unpaid SDLT, repayment of an excessive repayment, SDLT penalties, and interest on those penalties.
• Joint and several liability means HMRC can pursue any one responsible partner for all of the amount due.
• A partnership agreement may divide costs internally, but it does not prevent HMRC claiming the full amount from one responsible partner.
• A person who became a partner only after the effective date of the transaction is usually not liable for that earlier SDLT debt or penalty.
• If a penalty or interest arose from a default that happened after a new partner joined, that later-joining partner may still be jointly and severally liable if they are a responsible partner.
• In practice, it is important to identify the type of liability, the transaction’s effective date, when the person became a partner, and when any default occurred.

SDLT and partnerships: when responsible partners are jointly and severally liable

This page explains a narrow but important SDLT rule for ordinary partnerships. Where certain partners are treated as responsible for an SDLT obligation, their liability is usually joint and several. In practical terms, that means HMRC can pursue any one of those responsible partners for the full amount, not just that partner’s share. The timing of when a person became a partner can matter.

What this rule is about

The source material deals with SDLT liabilities arising in relation to ordinary partnership transactions. It is not setting out who the responsible partners are in the first place. Instead, it explains how liability works once a person falls within that category.

The key issue is whether each responsible partner is only liable for a proportion of the tax, interest or penalty, or whether each can be held liable for the whole amount. The rule says the liability is joint and several, subject to an important limit for people who only joined the partnership later.

What the official source says

The official material says that where the responsible partners are liable:

• to pay SDLT, or interest on unpaid SDLT,
• to repay an excessive repayment under Finance Act 2003 Schedule 10 paragraph 29, or
• to pay an SDLT penalty, or interest on such a penalty,

that liability is joint and several between those partners.

The source then adds an important qualification. Joint and several liability does not extend to responsible partners who joined the partnership only after the effective date of the transaction that gave rise to the SDLT liability or penalty. The exception is where the default that caused the penalty or interest happened after that person had become a partner.

What this means in practice

Joint and several liability means HMRC is not limited to collecting only a fraction of the amount from each responsible partner. If the partnership owes SDLT, interest, a repayment of excessive repayment, or a penalty, HMRC can usually pursue any one of the responsible partners for all of it.

That matters because the economic burden within the partnership and the legal liability to HMRC are not the same thing. A partnership agreement may say that liabilities are shared in a particular way, but that does not stop HMRC from seeking the full amount from one responsible partner if the statutory rule allows it.

The timing point is especially important when the membership of the partnership changes. A person who was not a partner when the relevant land transaction took effect is not automatically exposed to joint and several liability for that earlier transaction. But if a penalty or interest arises because of a later default, and that default happened after they became a partner, the source indicates that joint and several liability can extend to them in relation to that later default.

How to analyse it

A sensible way to approach the issue is to ask these questions in order:

• Is this an ordinary partnership transaction for SDLT purposes?
• Who are the responsible partners under the relevant SDLT rules?
• What kind of liability is in point: SDLT itself, interest on unpaid tax, recovery of an excessive repayment, a penalty, or interest on a penalty?
• What was the effective date of the transaction that triggered the SDLT liability or penalty?
• Was the person being considered already a partner on that effective date?
• If not, did the default giving rise to the penalty or interest occur only after that person became a partner?

This sequence matters because the source draws a distinction between liability tied to the original transaction and liability tied to a later default. A later-joining partner is not generally brought into joint and several liability for an earlier transaction merely because they later became a partner. But where the relevant failure happens later, after they joined, the position may be different.

Example

Illustration: a partnership enters into a land transaction, and SDLT becomes due. At that time, A and B are the responsible partners. Later, C joins the partnership.

If the issue is the SDLT due on that earlier transaction, the source indicates that joint and several liability falls on the responsible partners connected with that transaction, and it does not extend to C merely because C joined later.

But if, after C has joined, there is a default that gives rise to a penalty or interest, the source says the exclusion for later-joining partners does not apply where the default occurred after they became a partner. In that situation, C may fall within the joint and several liability for that penalty or interest, depending on whether C is a responsible partner for the purpose of the relevant rule.

Why this can be difficult in practice

The source is brief and assumes the reader already knows who counts as a responsible partner under the wider partnership provisions. In real cases, that can be the first area of difficulty.

Another practical difficulty is identifying exactly what triggered the amount HMRC is seeking. Tax due on the transaction, interest on unpaid tax, recovery of an excessive repayment, penalties, and interest on penalties are related but not identical. The timing rule for later-joining partners can produce different results depending on which of those liabilities is in issue and when the relevant default occurred.

There can also be a factual question about the date on which a person truly became a partner, especially if admission was agreed informally first and documented later. Since the source makes timing central, that factual point may matter.

Finally, the source is HMRC manual material. It is helpful for understanding HMRC’s view of the legislation, but the legal effect ultimately depends on the statutory provisions it is explaining.

Key takeaways

• Where responsible partners are liable for certain SDLT amounts, that liability is generally joint and several.
• HMRC can therefore pursue one responsible partner for the full amount, not just a proportion.
• A person who joined the partnership after the effective date of the transaction is not generally caught for that earlier liability, unless the penalty or interest arose from a default that happened after they became a partner.
