Late Tax Return Penalty for Partnership; Partner D Jointly Liable

Late SDLT partnership returns and partner liability for penalties

When an SDLT return for a partnership land transaction is filed late, the person liable for the penalty may not be the same person liable for the tax or interest. A partner who is a responsible partner when the filing failure happens can be jointly and severally liable for late filing penalties, even if they are not liable for the SDLT itself or for late payment interest.

• SDLT, late payment interest, and late filing penalties must be considered separately because the rules do not always make the same people liable for each.
• A new or continuing partner may face a fixed late filing penalty if they were a responsible partner when the return should have been filed.
• That partner does not automatically become liable for the underlying SDLT or the interest just because they were a responsible partner at that time.
• Daily penalties depend on timing: a person is only liable for the days on which they were actually a responsible partner.
• Joint and several liability means HMRC can recover the full penalty from any one liable partner, who must then seek any contribution from the others separately.

Late SDLT partnership returns: when a new partner can be liable for penalties but not the tax

This page explains a narrow but important SDLT point for ordinary partnership transactions: if a land transaction return is filed late, a person who is a responsible partner at the relevant time may be liable for penalties even if they are not liable for the underlying tax or interest. This matters where partnership membership changes between the effective date of the transaction and the date the return should have been filed or paid.

What this rule is about

In SDLT, partnership transactions have special rules about who must deal with the return and who is liable for tax, interest, and penalties. The source material deals with a situation where the partnership transaction has already happened, but the return and payment are made late.

The key issue is that liability does not work in exactly the same way for all amounts due. The legislation distinguishes between:

• the SDLT itself,
• interest on late payment, and
• penalties for failing to file on time.

A person may be a “responsible partner” for procedural purposes without becoming liable for every amount that arises.

What the official source says

The HMRC manual gives an example based on an earlier partnership example, but changes one fact: the SDLT return and tax payment were not made until 10 June 2019.

HMRC says that:

• a penalty and interest arise because the return was filed late,
• partner D is a responsible partner,
• D is not liable for the tax or the interest, and
• D is jointly and severally liable with the other partners for the fixed penalty because D was a responsible partner when the failure occurred that triggered the penalty.

The manual also says that if daily penalties were incurred, D would be liable for those too, but only if D was a responsible partner on the particular day or days for which those penalties were charged.

What this means in practice

The practical point is that you must look separately at each kind of liability.

Being a responsible partner does not automatically make someone liable for the SDLT itself or for interest. But it can make that person liable for penalties connected with a failure to meet filing obligations, if they were a responsible partner at the time the relevant failure happened.

This means a new or continuing partner can be exposed to penalty liability even where the tax relates to an earlier transaction and even where that partner is not liable for the tax itself.

The source material specifically treats the fixed late filing penalty by asking whether D was a responsible partner at the time when the return should have been filed. Because D was a responsible partner at that point, D is jointly and severally liable for that penalty.

The same time-based approach applies to daily penalties. The question is not simply whether D is a responsible partner when HMRC assesses the penalty, but whether D was a responsible partner on the day or days to which the daily penalty relates.

How to analyse it

When a partnership SDLT return is late, it helps to work through the issue in stages.

• Identify the transaction and the filing deadline.
• Establish when the return was actually filed and when payment was actually made.
• Separate the possible liabilities: tax, interest, fixed penalty, and any daily penalties.
• Identify who was a responsible partner at the date the return should have been filed.
• If daily penalties are in point, identify who was a responsible partner on each relevant day.
• Do not assume that liability for tax and interest matches liability for penalties. The source material shows that it may not.

The phrase “jointly and severally liable” matters. In practice, it means HMRC may pursue any one of the liable persons for the full amount of the penalty, leaving that person to sort out any contribution issues with the others separately.

Example

Illustration: a partnership land transaction takes place and an SDLT return should have been filed by a particular deadline. Before that deadline, D becomes a partner and is a responsible partner when the filing obligation falls due. The return is not filed until much later.

On the HMRC approach in the source material, D is not liable for the SDLT or the interest merely because D is now a responsible partner. But D is liable, together with the other relevant partners, for the fixed late filing penalty because D was a responsible partner when the failure to file on time occurred.

If the delay continues and daily penalties arise, D is liable for those only for the days on which D was a responsible partner.

Why this can be difficult in practice

The difficulty is usually not the legal principle but the timing and status questions.

You need to know exactly when the return was due, when any penalty was triggered, and who counted as a responsible partner at that time. If partnership membership changed around the filing deadline, or if someone became or ceased to be a responsible partner during the period of default, liability may differ between the fixed penalty and any daily penalties.

Another practical difficulty is that readers may assume that the person liable for the SDLT must also be liable for all late filing consequences. The source material shows that this is not necessarily correct. The legislation can allocate liability differently for tax and for penalties.

Key takeaways

• For partnership SDLT returns, liability for tax and interest is not always the same as liability for penalties.
• A responsible partner can be jointly and severally liable for a fixed late filing penalty if they were a responsible partner when the filing failure occurred.
• For daily penalties, liability depends on whether the person was a responsible partner on the particular day or days concerned.
