Do you pay higher rate SDLT if you sold your old home more than three years ago and currently own no other property?

Introduction

People often worry about the SDLT “three-year rule” when there has been a gap between selling one home and buying the next. A common example is where someone sells their previous main residence, lives with family or in temporary accommodation for several years, and then later buys another home.

The key point is that the higher rates for additional dwellings usually depend on what residential property you own at the end of the day of completion. If you do not own any other dwelling at that point, the higher rates will generally not apply.

The Question

A homeowner sold their previous main residence, moved in with family while looking for another property, and has now been out of the market for more than three years. They do not own any other residential property. They want to know whether, when they eventually buy a new home to live in as their only residence, the higher rate of SDLT will apply because more than three years have passed since the earlier sale.

Nick’s Explanation

Nick’s view was that the higher rate should not apply on these facts, provided the new purchase will be the buyer’s only residential property at completion.

In substance, his reasoning was:

• the higher rates under Schedule 4ZA to the Finance Act 2003 apply where, at the end of the effective date, the buyer has a major interest in another dwelling worth at least £40,000, and the new purchase is not treated as a replacement of the buyer’s only or main residence;
• if the buyer no longer owns the old home and does not own any other dwelling when the new purchase completes, that basic condition is not met;
• the “three-year rule” is mainly relevant where someone still owns more than one dwelling on completion and needs to rely on the replacement rules or a later refund mechanism.

Put shortly, where a buyer has already sold their previous home and owns no other dwellings at completion, the higher rates are generally not triggered in the first place.

The Law

SDLT on residential property is charged under Part 4 of the Finance Act 2003. The standard residential rates are set by section 55.

The higher rates for additional dwellings are contained in Schedule 4ZA to the Finance Act 2003. Broadly, paragraph 3 applies the higher rates if, at the end of the effective date of the transaction:

• the purchaser has a major interest in another dwelling,
• that interest has a market value of £40,000 or more, and
• the purchased dwelling is not a replacement for the purchaser’s only or main residence.

Paragraphs 5 to 8 of Schedule 4ZA deal with replacement of only or main residence. These provisions are often described as the “three-year rule”. In broad terms, they help where a buyer owns more than one dwelling on completion but is replacing their main residence, or where they pay the higher rates first and later dispose of the former main residence within the permitted period so as to qualify for a repayment.

That timing rule is important in many cases, but it does not create a free-standing charge. The higher rates still depend first on the statutory conditions being met on completion.

Analysis

Applying the rules step by step:

1. Identify what the buyer will own at the end of the day of completion.

   If the buyer will own only the newly purchased dwelling, and no other dwelling interests worth at least £40,000, paragraph 3(1)(a) is not satisfied.

2. Ask whether the buyer still has a major interest in another dwelling.

   On these facts, the previous home has already been sold and there is no other property ownership. So there is no “other dwelling” for the purposes of the higher rates test.

3. Consider whether the three-year replacement rules matter.

   In this scenario, they usually do not. Those rules matter where a buyer would otherwise be caught because they own more than one dwelling at completion, or where they need a refund after later selling a former main residence. If there is no second dwelling owned at completion, there is normally no higher-rate charge to disapply or reclaim.

4. Check for anything else that could bring the higher rates back into play.

   That could include a share in another dwelling, inherited property interests, overseas residential property, or a joint purchase with someone who owns another dwelling. Spouses and civil partners can also be treated as one unit for these purposes in some situations.

So, where a person sold their old home years ago, has since owned no other residential property, and is now buying a single home to live in, the passage of more than three years since the sale does not by itself create higher-rate SDLT.

Outcome

On the stated facts, the buyer should usually pay SDLT at the standard residential rates, not the higher rates for additional dwellings.

The fact that more than three years have passed since the sale of the former main residence does not, on its own, cause the surcharge to apply where the buyer owns no other dwelling at completion.

Practical Steps

• Check exactly what residential property interests you will own at completion, including small shares, inherited interests and overseas property.
• If buying jointly, check the position of the other buyer as well, especially if they are a spouse or civil partner or already own a dwelling.
• Keep evidence showing that your previous home was sold, such as the sale contract and completion statement.
• Ask your conveyancer to confirm the SDLT treatment before filing the return.
• If there is any unusual feature, such as trust ownership, separation from a spouse, inherited property or mixed-use land, get specific SDLT advice.

Conclusion

If you sold your previous home, have owned no other residential property since, and are now buying a new home as your only property, the higher rate of SDLT will usually not apply. The three-year rule is mainly relevant where a buyer owns more than one dwelling on completion and needs the replacement residence provisions or a later refund.
