Who We Are
Accountants who understand commercial development economics
Commercial developers deal with standard-rated VAT on most construction work, complex SDLT on mixed-use sites, and substantial capital allowances opportunities within fixtures and fittings — areas where generalist accountants often leave money on the table . We track your project from land purchase through to letting or disposal, structuring each stage for tax efficiency.

Capital Allowances on Commercial Schemes
Unlock up to £1 million in first-year tax relief per project
The Annual Investment Allowance lets you deduct up to £1 million of qualifying plant and machinery, electrical systems, heating, lifts, air conditioning, sanitary ware against profits in the year of purchase, rather than spreading relief over many years . At the 25% main Corporation Tax rate, that’s a potential £250,000 tax saving on a single scheme .
From 1 January 2026, a new 40% first-year allowance also applies to qualifying assets, including those purchased for leasing, widening the relief available beyond AIA alone . We prepare a full capital allowances computation on every commercial fit-out so nothing qualifying is left unclaimed.

VAT on Mixed-Use & Commercial Construction
Get VAT classification right before contracts are signed
Most commercial construction is standard-rated at 20%, but mixed-use schemes with a residential element can qualify for reduced or zero rates on that portion, and incorrect upfront classification can mean irrecoverable VAT losses running into hundreds of thousands of pounds on larger schemes. We review contracts and scheme design before construction starts to ensure the correct VAT liability is applied and, where partial exemption applies, that recovery is maximised.

Common Pain Points
The Common Tax Challenges Commercial Developers Face
Commercial schemes involve larger sums, longer timelines, and more moving tax variables than most other property niches.
SDLT on Mixed-Use Sites
Sites combining commercial and residential elements can qualify for non-residential SDLT rates on part of the price, but miscalculating the split leads to significant overpayments.
Under-Claimed Capital Allowances
Fixtures within a commercial fit-out — wiring, HVAC, lifts routinely go unclaimed when the acquisition isn’t broken down correctly at completion .
VAT Partial Exemption Complexity
VAT recovery on high-value commercial buildings must be monitored and adjusted over a 10-year period as usage changes, a rule frequently missed after year one.
Capital Goods Scheme Adjustments
A single late CIS return, four late payments, or a payment over 14 days late can trigger HMRC to cancel gross status, forcing a full year’s wait before reapplying
Financing and Interest Deductibility
Development finance structures need careful review to ensure interest relief is maximised and correctly allocated between trading and investment activity.

FAQS
Commonly Asked Tax & Accounting Questions
How much can I claim through the Annual Investment Allowance?
Up to £1 million of qualifying plant and machinery per 12-month accounting period, pro-rated for shorter or longer periods .
What's the new 40% first-year allowance?
From 1 January 2026, a permanent 40% first-year allowance applies to qualifying plant and machinery, including assets purchased for leasing and by unincorporated businesses.
Is commercial construction always standard-rated for VAT?
Generally yes, at 20%, though mixed-use schemes with a residential element may qualify for reduced or zero rates on that portion.
What is the Capital Goods Scheme?
It’s an HMRC rule requiring VAT recovery on high-value capital items (including commercial buildings) to be reviewed and adjusted annually over up to 10 years if the building’s use changes.
Why choose Construction Tax Accountants for commercial development?
We specialise in construction and property tax specifically, so capital allowances, VAT classification, and SDLT structuring are handled with sector-specific precision, not generic advice.
How is SDLT calculated on a mixed-use site?
SDLT is apportioned between residential and non-residential elements based on the value attributable to each, with non-residential rates often applying to the whole transaction where genuinely mixed.
Do I have to file a CGT return even if no tax is due?
From 6 April 2025, the separate Furnished Holiday Let (FHL) tax regime was abolished. Properties previously qualifying as FHLs are now treated as ordinary property businesses. This means the loss of several advantages that FHL status provided: 100% mortgage interest deductibility, capital allowances on furniture and fittings, relief for pension contributions against FHL profits, and Business Asset Disposal Relief (10% CGT) on sale.
Does my SA business need to be VAT registered?
Short-term accommodation income whether from Airbnb, Booking.com, direct bookings, or any other source is standard-rated for VAT at 20%. If your total turnover from SA activities exceeds £90,000 in any 12-month rolling period, VAT registration is mandatory. Below this threshold, voluntary registration may be beneficial if you incur significant VAT on costs (refurbishment, furniture, maintenance) that you can then reclaim. VAT registration also makes your pricing more transparent to corporate guests who can reclaim VAT themselves. We advise on both the timing and management of VAT registration.
Does UK Property Tax Accountants handle both the CGT return and the Self Assessment return?
Capital allowances allow you to deduct the cost of qualifying capital expenditure against your taxable profit. For SA and hotel businesses, qualifying assets include furniture, fixtures and fittings, white goods, technology, integrated building services (heating, plumbing, electrical), and commercial vehicles. The Annual Investment Allowance (AIA) provides 100% upfront relief on qualifying expenditure up to £1 million per year. For hotel and SA property acquisitions, an embedded capital allowances survey identifies qualifying fixtures within the building fabric that can be claimed.
Should my SA business be in a limited company?
The optimal structure depends on your circumstances particularly your income level, portfolio size, and long-term goals. A limited company pays Corporation Tax at 19–25% on profits, which is lower than the 40–45% Income Tax rates facing higher earners. However, extracting profit from a company creates a second layer of personal tax on dividends or salary. With the abolition of the FHL regime, many of the tax advantages that previously favoured personal ownership have been reduced, making the limited company structure relatively more attractive. We model both scenarios for each client before recommending a structure.
What are the business rates obligations for SA properties?
In England, a self-contained SA property that is available for short-term letting for at least 140 days per year and actually let for at least 70 days is assessed for business rates rather than Council Tax. In Scotland and Wales, slightly different thresholds apply. Properties assessed for business rates may qualify for Small Business Rate Relief (100% relief for rateable values below £12,000; tapered relief between £12,000 and £15,000). Some SA operators benefit from business rates by accessing this relief and avoiding Council Tax. We advise on classification and relief applications for your specific property.
