Guidance on SDLT Higher Rate for Non-Natural Persons and Further Returns

Further SDLT returns when higher rates for additional dwellings no longer apply

If SDLT was originally paid at the higher rates for an additional dwelling, but a later event means those higher rates should be withdrawn, HMRC requires a further SDLT return. This must usually be sent within 30 days of the date the relevant conditions first stopped being met, and that date is treated as the effective date for filing, penalties and interest.

• A further return is needed if the higher SDLT rates were correctly charged at first, but later no longer apply under the withdrawal rules.
• The return must be made to HMRC Stamp Taxes by letter within 30 days of the date the relevant conditions were first no longer met.
• The letter should include the original unique transaction reference number, a fresh self-assessment of the SDLT now due, and payment of that amount.
• For this further return, the key date is not the original completion date but the later date when the conditions ceased to be met.
• Late filing, penalties and interest are worked out by reference to that later date, so identifying it correctly is very important.
• Taxpayers must check both whether the withdrawal rules apply and whether the revised SDLT calculation has been done correctly.

Further SDLT returns when the higher rates for additional dwellings stop applying

This page explains what happens if SDLT was originally paid at the higher rates for additional dwellings, but later events mean those higher rates should no longer apply. In that situation, HMRC says a further return must be made within a set time limit. This matters because the later return is treated as a tax return in its own right for notification, penalties and interest.

What this rule is about

The source deals with a specific follow-up obligation after an SDLT return has already been filed. It applies where:

• SDLT was paid at the higher rates for additional dwellings on the original acquisition, and
• the statutory withdrawal provisions later apply, so the conditions that originally triggered the higher rates are no longer met.

The point of the rule is not to revisit the whole transaction from scratch. It is to require a new return once the legal basis for the earlier higher-rate charge falls away.

What the official source says

The HMRC manual says that where SDLT at the higher rates for additional dwellings was paid because the relevant conditions were met, and the withdrawal provisions are later to apply, a further return must be made within 30 days of the date when those relevant conditions were first no longer met.

According to the source:

• the further return must be made by letter to HMRC Stamp Taxes,
• the letter must include the unique transaction reference number of the original return,
• the letter must contain a self-assessment of the tax now due, and
• a cheque for that amount should be sent with the letter.

The source also states that, for notification, penalty and interest purposes, the effective date of the further return is not the original completion date. Instead, it is the date on which the relevant conditions were first no longer met.

Finally, the manual says that the rules in Schedule 10 to Finance Act 2003 apply to this further return in broadly the same way as they apply to an ordinary land transaction return under section 76, but with references to the transaction’s effective date read instead as references to the date when the relevant conditions ceased to be met.

What this means in practice

If a buyer originally paid SDLT on the basis that the higher rates for additional dwellings applied, they cannot simply assume that HMRC will adjust the position automatically if the withdrawal provisions later become relevant. The source says a further return is required.

The 30-day time limit runs from the date when the relevant conditions were first no longer met. That date is important because it drives:

• when the further return is due,
• whether there is a late filing issue, and
• how penalties and interest are worked out.

The further return must include a recalculation of the SDLT now due. In other words, the taxpayer must work out the revised tax position once the withdrawal provisions apply, rather than merely notifying HMRC that circumstances have changed.

The source is procedural as well as substantive. It tells the reader both that a further return is needed and how HMRC expects it to be made.

How to analyse it

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

• Was SDLT originally paid at the higher rates for additional dwellings?
• Was that because the relevant statutory conditions were met at the time of the acquisition?
• Has a later event triggered the withdrawal provisions so that those conditions are now treated as no longer met?
• On what exact date were the relevant conditions first no longer met?
• What amount of SDLT is now due on a self-assessment basis?
• Has the further return been sent to HMRC within 30 days of that date?

It is especially important to identify the correct trigger date. The source treats that date as the effective date for the further return. If that date is identified wrongly, the taxpayer may misjudge the filing deadline and any exposure to interest or penalties.

It is also worth separating two issues:

• the substantive question of whether the withdrawal provisions apply at all, and
• the procedural question of how and when to notify HMRC once they do apply.

The source page is mainly about the second issue, but the first must be answered correctly before the filing obligation can be handled properly.

Example

This is an illustration only. A buyer acquires a residential property and files an SDLT return on the basis that the higher rates for additional dwellings apply. Later, an event occurs that means the statutory withdrawal provisions now apply, so the conditions that originally justified the higher rates are no longer met. On the date that change first takes effect, the buyer has 30 days to make a further return to HMRC Stamp Taxes. The buyer must identify the original transaction by its reference number, recalculate the SDLT now due, and send the revised self-assessment with payment in the form required by the source.

Why this can be difficult in practice

The source is short, but the underlying issue can be fact-sensitive.

First, the hardest question is often not how to file the further return, but whether the withdrawal provisions actually apply. That depends on the detailed statutory conditions, which are not set out on this page.

Second, the phrase “the date when the relevant conditions were first not met” can be straightforward in some cases but less obvious in others. Where events unfold over time, it may not be immediately clear which date starts the 30-day clock.

Third, the source refers to a self-assessment of “the tax now due”. That requires a correct recalculation under the legislation. If the revised amount is wrong, the taxpayer may still face compliance issues even if the return is sent on time.

Finally, the source refers to Schedule 10 applying in the same way as for an ordinary SDLT return, subject to the modified effective date rule. In practice, that means the further return should be treated with the same care as any other SDLT filing, because the usual compliance consequences can still arise.

Key takeaways

• If SDLT was originally paid at the higher rates for additional dwellings, and later events mean the withdrawal provisions apply, a further return is required.
• The return must be made within 30 days of the date when the relevant conditions were first no longer met.
• That later date, not the original transaction date, is used for notification, penalty and interest purposes for the further return.
