Situation 03
Replacing your main residence
The replacement exception is one of the most valuable positions in stamp duty and one of the easiest to lose. It turns on dates, on what counts as your main residence, and on evidence.
The short answer
Almost every dispute in this area is a dispute about timing or about facts, not about the law. Which is why it is worth establishing both before completion rather than arguing about them afterwards.
Where this usually goes wrong
These are the patterns we see most often. Each one is a situation where the obvious answer and the correct answer are different.
The chain that broke
The sale that was going to complete first did not. What was a straightforward replacement becomes something else entirely, on the same day.
Which property was actually the main residence
This is a question of fact, not of declaration, and it is evidenced by how the properties were used, not by what was intended.
More than one property in the picture
Where several properties have been occupied over the relevant period, establishing which one the test applies to is the whole question.
Marriage, separation and joint ownership
The position of a spouse or civil partner can change the answer, including where they are not on either title.
Assuming nothing can be done afterwards
Where the disposal happens later than expected, there may still be a route. It is time limited and it depends on the facts.
The facts that decide it
If you want to know where you stand before you speak to anyone, these are the questions we will ask. Having the answers ready is most of the work.
- 01What are the exact dates of the purchase and the disposal?These are taken from the completion documents rather than from recollection.
- 02Which property was your main residence, and on what evidence?This is established from records of how each property was used, not from a statement of intention.
- 03How long was each property occupied, and by whom?The pattern of occupation across the whole period is what the documents have to show.
- 04Was the disposal of your entire interest?A part disposal and a whole disposal are different facts, so we read the transfer itself.
- 05What is the position of your spouse or civil partner?Their holdings and disposals are looked at alongside yours rather than separately.
- 06Has an SDLT return already been filed, and at which rates?What was declared, and on what basis, determines what the next step can be.
- 07Were there any intervening property transactions?Anything bought or sold in between forms part of the sequence we have to map.
- 08Is there documentary evidence of occupation for each period?We ask for records created at the time rather than assembled after the event.
What we would want to see
The analysis is only as good as the documents behind it. For this situation, that normally means:
- Contracts for both the purchase and the disposal
- Evidence of occupation of each property
- Completion statement, where available
- Details of every property interest held
- Evidence of any disposal and its date
- Details of all purchasers and their positions
- Any existing SDLT return and UTRN
- Correspondence with the conveyancer on the point
Questions we get on this
My sale fell through on the day of completion. Where does that leave me?
It leaves the position to be worked out on the actual dates rather than the intended ones. The starting point is what completed and in what order, taken from the completion documents, not from what the chain was supposed to do.
How do I show which property was my main residence?
By how the properties were used rather than by stating a preference. We look for records covering each period of occupation, which is why we ask for material that was created at the time rather than put together later.
The disposal happened after the purchase. Is that the end of it?
Not necessarily. Where a disposal follows the purchase there may still be a route, and whether there is depends on the facts and on what has already been filed. We establish the correct position first and then look at what can be done with it.
Will you just tell me what I want to hear?
No. Our fee is fixed and does not depend on the outcome, which means we have no interest in finding a saving that is not there. If the original return was right, we will tell you that in writing, and you will have a reasoned position on file if it is ever looked at.
