Guidance on LBTT Returns for Later Linked Transactions and Associated Penalties

LBTT linked transactions and filing a return for an earlier deal

If a later Scottish property transaction is linked to an earlier one, it can change the LBTT due on the earlier transaction. Where this makes the earlier deal notifiable, creates tax, or increases tax already due, the buyer must file an LBTT return or further return for the earlier transaction within 30 days starting the day after the later transaction’s effective date, and pay the tax at that point.

• Do not simply amend the original return if a later linked transaction changes the LBTT position of an earlier one.
• A new return or further return is needed if the earlier transaction becomes notifiable, tax becomes payable, or more tax is due.
• The filing deadline runs from the effective date of the later linked transaction, not the earlier transaction.
• The tax on the earlier transaction is still calculated using the LBTT rates and bands in force on the earlier transaction’s effective date.
• Payment is due when the return is submitted, and late filing, inaccuracies, or late payment can lead to penalties and interest.
• Keep clear records showing why the transactions are linked and how the revised LBTT has been worked out.

LBTT linked transactions: when a later deal means you must file a return for an earlier one

This page explains what happens if you enter into a later land transaction that is linked to an earlier transaction for Scottish Land and Buildings Transaction Tax purposes. In some cases, the later transaction changes the LBTT position on the earlier one. When that happens, you may need to file a new LBTT return or a further return for the earlier transaction, and pay extra tax within a strict deadline.

What this rule is about

LBTT looks at linked transactions together. A later transaction can affect how much tax was due on an earlier transaction, even if the earlier transaction has already completed and its LBTT position seemed settled at the time.

The rule dealt with here is procedural as well as substantive. It is not just about recalculating the tax. It is also about what kind of return must be filed, when it must be filed, and what date and tax rates must be used.

This matters because a buyer might assume that the original return can simply be amended. The official guidance says that is not the correct route where a later linked transaction changes the earlier transaction’s LBTT position in the ways described below.

What the official source says

Revenue Scotland says that where a later linked transaction causes any of the following in relation to an earlier transaction:

• the earlier transaction becomes notifiable,
• more tax becomes payable on the earlier transaction, or
• tax becomes payable on the earlier transaction when none was payable before,

the buyer must file an LBTT return or a further LBTT return. The buyer must not deal with this by amending the original return.

The return is due within 30 days beginning with the day after the effective date of the later linked transaction. Revenue Scotland refers to this as the filing date.

For the “relevant date” field in the return, the date to use is the effective date of the later linked transaction.

The return must include an assessment of the tax due. That tax is calculated using the LBTT rates and bands that applied at the effective date of the earlier transaction, not the later one.

Payment is due when the return is submitted.

The guidance also notes that amendments may be possible, subject to restrictions, up to 12 months after the filing date. That is a separate point from the requirement to file a return or further return in the first place.

What this means in practice

If you buy land or property in more than one linked stage, do not look at each transaction in isolation. Once the later linked transaction happens, you must revisit the earlier one.

The practical consequences are:

• you may need to file a return for the earlier transaction even if no return was needed at the time,
• you may need to file a further return for the earlier transaction if extra LBTT is now due,
• the deadline runs from the later transaction’s effective date, not from the earlier one, and
• the tax calculation for the earlier transaction still uses the earlier transaction’s rates and bands.

This combination can catch people out. The trigger is the later linked transaction, but the tax calculation looks back to the earlier transaction’s effective date.

In administrative terms, Revenue Scotland also notes that if a further LBTT return does not let you amend the tax figure correctly through the online process, you should send a secure message with the original and new Revenue Scotland reference numbers and the new tax payable figure so Revenue Scotland can update the calculation.

How to analyse it

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

1. Is there a later transaction?
2. Is that later transaction linked to an earlier transaction?
3. Does the existence of the later linked transaction change the LBTT result for the earlier transaction?
4. If so, does it make the earlier transaction notifiable, increase the tax on it, or create tax where none was previously payable?
5. If yes, has a return or further return been prepared for the earlier transaction rather than merely amending the original filing?
6. Has the filing deadline been identified correctly as 30 days from the day after the effective date of the later linked transaction?
7. Has the tax been calculated using the rates and bands in force at the effective date of the earlier transaction?
8. Is payment ready to be made when the return is submitted?

You should also keep records showing why the transactions are linked, how the revised tax was calculated, and why the filing position changed. The source material makes clear that record-keeping obligations apply whether or not a return is required.

Example

This is a simple illustration of the mechanics.

A buyer enters into an earlier land transaction. At that point, based on that transaction alone, no LBTT is payable or the transaction is not notifiable. Later, the same buyer enters into a second transaction that is linked to the first. Looking at the linked transactions together changes the LBTT outcome for the first transaction.

When the second transaction becomes effective, the buyer must revisit the first one. If the first transaction now becomes notifiable, or if additional LBTT is due on it, the buyer must file an LBTT return or further LBTT return for the first transaction. The deadline is 30 days from the day after the effective date of the second transaction. The tax for the first transaction is calculated using the rates and bands that applied when the first transaction became effective.

Why this can be difficult in practice

The main difficulty is that the filing trigger and the tax calculation point to different dates.

The deadline is driven by the later linked transaction. But the tax rates and bands are taken from the earlier transaction’s effective date. If rates changed between those dates, this can feel counterintuitive.

Another difficulty is procedural. A buyer may think the right step is to amend the original return. The guidance says that where the later linked transaction causes the earlier transaction to become notifiable or increases the tax on it, the correct step is to file a return or further return instead.

There can also be practical uncertainty around whether transactions are in fact linked. This page assumes that they are linked and focuses on the filing consequences. If linkage itself is uncertain, that issue must be resolved first because it drives the whole analysis.

Finally, penalties and interest can arise in more than one way. A late return can trigger a late-filing penalty. An inaccurate return can lead to an inaccuracy penalty. Late payment can lead to a payment penalty, and interest runs on unpaid tax from the filing date until payment. That makes it important to identify the trigger date correctly and to calculate the revised tax carefully.

Key takeaways

• A later linked transaction can change the LBTT position of an earlier transaction.
• If that happens, the buyer must file an LBTT return or further LBTT return for the earlier transaction, not just amend the original return.
• The filing deadline is based on the later transaction’s effective date, but the tax is calculated using the rates and bands in force at the earlier transaction’s effective date.
