The rules become more important for a buy-to-let company or property SPV once it also makes taxable supplies. This guide explains what counts towards the £90,000 VAT threshold for property companies specifically, when registration is required, and when voluntary VAT registration could make sense.
Key Takeaways
Is Registering a Buy-to-Let Limited Company for VAT Mandatory?
This is the key point many landlords miss: total income and taxable turnover are not the same thing. A company could receive £120,000 a year entirely from exempt residential rent and still have £0 of taxable turnover if it makes no other taxable supplies. In simple terms, taxable sales count towards the VAT threshold; ordinary residential rent usually does not.
Why Residential Rental Income is Usually VAT-Exempt?
The downside is that VAT on costs linked to the rental business is usually not recoverable.
For example,
Imagine a company receives £120,000 a year in residential rent and has no other taxable income. That rent would not normally count towards the VAT threshold. If the company then pays £6,000 plus £1,200 VAT for property repairs, the £1,200 VAT would usually become an extra cost to the business rather than something it could reclaim. The position may be different if the company also makes taxable supplies.
What is the £90,000 VAT Registration Threshold for Limited Companies
There are two main ways a limited company can be required to register for VAT, and either one can trigger registration. For property companies, the key point is simple: HMRC looks at taxable turnover, not just the total amount of money coming into the business. The current VAT registration threshold is £90,000.
The Rolling 12-month Test
The Next 30-day Test
Worked Example: Residential Buy-to-Let Company
Scenario: A property SPV owns six flats and receives £96,000 in residential rent during the 12 months to 31 July 2026. It has no other taxable income.
Calculation: Ordinary residential rent is generally VAT-exempt, so the £96,000 does not count towards the VAT registration threshold. The company’s taxable turnover is therefore £0, not £96,000.
Result: The company does not need to register for VAT just because its residential rental income is above £90,000. What matters is taxable turnover, and in this example, there is none.
These figures are illustrative. The correct VAT position depends on your specific facts.
When Does a Buy-to-Let Company's VAT Position Change?
Residential rent is usually VAT-exempt, but not every type of property income is treated the same way. If your buy-to-let company starts making taxable supplies, their value can count towards the £90,000 VAT registration threshold. The key is to separate taxable supplies from exempt residential rent.
Common examples include:
Holiday lets & Serviced accommodation
Holiday accommodation is normally standard rated for VAT. Many serviced apartments and short-stay properties provided as holiday or visitor accommodation can also be taxable. However, simply listing a property on Airbnb or letting it for a short period does not, by itself, decide the VAT treatment.
Commercial Property with an option to tax
Commercial rent is generally exempt, but if the landlord has made an effective option to tax, the rent will normally become standard-rated and count towards taxable turnover.
Parking and other property income
Garages or parking spaces let separately from a dwelling are standard-rated, because parking facilities are excluded from the residential VAT exemption. Where a garage or parking space is let to the same tenant together with the dwelling, it is normally treated as part of the single exempt residential supply.
Note
If your company receives both exempt residential rent and taxable supplies, do not simply add all the income together. Track the taxable amounts separately and monitor both the rolling 12-month VAT threshold and the next-30-day test.
Worked Example: Mixed Property Portfolio Crossing the VAT Threshold
Scenario: A property company earns the following in the 12 months to 30 June 2026:
- £40,000 from ordinary residential rent
- £84,000 from taxable serviced accommodation for visitors or travellers
- £10,000 from a commercial unit where an effective option to tax applies
The £40,000 residential rent is generally VAT-exempt, so it does not count towards the VAT registration threshold. The serviced accommodation and opted commercial rent do count because they are taxable supplies.
- Taxable turnover: £84,000 + £10,000 = £94,000
Because £94,000 is above the £90,000 VAT registration threshold, the company would normally need to register for VAT under the rolling 12-month test.
The key point:
Do not use your company's total property income when checking the VAT threshold. Separate the taxable income from the exempt residential rent and only include the taxable amounts.
This example is for illustration only. The VAT treatment of serviced accommodation and commercial property can depend on the circumstances, so each income stream should be checked separately.
How to Register a Buy-to-Let Limited Company for VAT
If your property company needs to register for VAT, the process is usually simple:
Can a Property Company Voluntarily Register for VAT?
Yes, but only if the property company makes, or genuinely plans to make, taxable supplies. A property company can register voluntarily even when its taxable turnover is below £90,000. The main benefit is that it may be able to reclaim VAT on certain business costs, such as refurbishment, fit-out work or professional fees, where those costs relate to taxable activities.
For a property company that only receives VAT-exempt residential rent, voluntary registration will generally not be available on that activity alone. VAT on costs linked to the residential letting is also usually not recoverable. If the company has a mix of taxable and exempt income, the partial-exemption rules are used to work out how much VAT can be reclaimed. Registering for VAT also means keeping digital VAT records and submitting VAT Returns under Making Tax Digital for VAT, unless an exemption applies.
What Happens If Limited Companies Don't Register for VAT on Time?
Missing the VAT registration deadline can be expensive. HMRC can backdate your registration to the date you should have registered, meaning VAT may be due on taxable sales from that date even if you did not charge it to customers. Eligible input VAT can reduce the amount owed, but any VAT you cannot recover may become a cost to the business.
Late registration may also lead to a failure-to-notify penalty. The amount depends on the circumstances, including whether the failure was deliberate and how and when it is disclosed to HMRC. If your property's taxable income is approaching the VAT threshold, checking it early can prevent a small oversight from becoming a much bigger VAT problem.
Waiting for your VAT Number?
You cannot show VAT separately on an invoice until HMRC issues your VAT registration number. If your registration has already taken effect, you can increase the total amount charged to cover the VAT due and issue a corrected VAT invoice once your number arrives.
Frequently Asked Questions
Yes, sometimes. You can usually reclaim VAT on goods bought up to four years before registration if you still hold them, and on services received up to six months before registration, provided the costs relate to taxable business activities.
You may qualify for an exception from VAT registration if the breach is temporary and HMRC accepts that your taxable turnover will fall below the £88,000 deregistration threshold over the next 12 months. You must apply, it is not automatic.
Yes. A company can usually apply to cancel its VAT registration if taxable turnover is expected to fall below £88,000. If the company has opted a property to tax, cancelling the VAT registration does not automatically cancel that option.
Usually, yes. Each genuinely separate limited company normally has its own £90,000 VAT threshold. However, HMRC can challenge arrangements where businesses are artificially split simply to avoid VAT registration.
Yes, if they qualify for VAT group registration. The group uses one VAT number and submits one VAT Return, although all members can be jointly responsible for the group’s VAT debts.
It depends. Many capital property sales are excluded from taxable turnover, but taxable sales of opted property can count. Exempt property sales normally do not count, so the VAT treatment of the sale should be checked first.
Conclusion
For most buy-to-let companies that only earn VAT-exempt residential rent, VAT registration will not usually be required. But once taxable income appears, such as serviced accommodation or opted commercial rent, the £90,000 VAT threshold can quickly come into play.
The key is knowing the difference between total income and taxable turnover. Keeping an eye on the right figure can help you avoid backdated VAT, penalties and unnecessary admin. If you are unsure where your company stands, a VAT review can give you clarity before the issue becomes costly.
