Capital allowances can provide legitimate tax relief for investors buying or improving qualifying commercial property in the UK. Where the property is held through an LLP with individual members, the relief can reduce the LLP’s taxable profit before that profit is allocated to members.

This may reduce members’ personal Income Tax. It does not make a transaction tax-free, provide a cash refund or remove the need for proper tax reporting. Capital allowances are statutory reliefs. Claims must relate to qualifying expenditure, have commercial substance and be supported by appropriate records.

How an LLP affects capital allowances

An LLP is generally tax transparent. The LLP normally calculates its taxable profit, claims available capital allowances and then allocates the adjusted profit or loss to its members.

For an LLP whose members are all within the charge to Income Tax, HMRC treats the LLP as a “notional individual” for the purpose of calculating taxable profits. Capital allowances are deducted in that calculation. The resulting profit is then shared according to the commercial profit-sharing arrangement in force for the relevant period.

The process is usually:

  1. The LLP calculates rental or trading income.
  2. Allowable revenue costs are deducted.
  3. Qualifying capital expenditure is identified.
  4. Capital allowances are claimed by the LLP.
  5. The adjusted profit or loss is allocated to members.
  6. Members report their allocated shares on their personal tax returns.

If an LLP has a company member, the position changes. The LLP may need separate computations for members subject to Income Tax and Corporation Tax. An LLP with a company member is not eligible for the Annual Investment Allowance. Different reliefs may apply to the corporate member, subject to the relevant conditions.

What expenditure can qualify?

Capital allowances generally apply to qualifying plant and machinery used in a business or property business. Examples in a commercial property can include:

  • Shop equipment and trade equipment
  • Commercial kitchen and bathroom fittings
  • Electrical installations
  • Heating, ventilation and air-conditioning systems
  • Lifts
  • Fire alarms and security systems
  • CCTV
  • Certain lighting systems
  • Some fixtures integrated into the building

Integral features, such as electrical systems, heating systems and ventilation, commonly fall into the special rate pool. Other qualifying plant and machinery may fall into the main pool.

The Structures and Buildings Allowance (SBA) may also apply to qualifying construction, renovation, conversion and fitting-out costs for new non-residential structures. The standard SBA rate is 3% per year for qualifying expenditure, subject to the rules and documentation requirements.

The following generally do not qualify for plant and machinery allowances:

  • Land
  • The general building and structure itself, outside the SBA rules
  • Most cars
  • Fixtures and equipment in dwelling-houses used for residential letting

For a shop-and-upper property, the commercial area and residential area must be considered separately. The commercial part may contain qualifying fixtures and works. Residential flats generally do not qualify for plant and machinery allowances in the same way.

Main capital allowance reliefs in 2026

Annual Investment Allowance

The Annual Investment Allowance allows 100% of most qualifying plant and machinery expenditure to be deducted in the period of purchase, up to the £1 million annual limit.

For an LLP, AIA is available only where all members are individuals. An LLP with a company member cannot claim AIA. The limit may also need adjustment where the accounting period is shorter or longer than 12 months.

AIA can apply to qualifying commercial fixtures, but the expenditure must meet the statutory requirements. It cannot be assumed that every item included in a property purchase qualifies.

Writing-down allowances

Expenditure not covered by AIA or another first-year allowance may enter a capital allowance pool.

For chargeable periods beginning on or after:

  • 6 April 2026 for Income Tax purposes
  • 1 April 2026 for Corporation Tax purposes

the main rate is reduced from 18% to 14%. Special rate assets are subject to a lower rate, currently 6%.

These rates can change. Confirm the applicable rate for the relevant accounting or tax period.

40% first-year allowance

From 1 January 2026, a 40% first-year allowance is available for qualifying new and unused plant and machinery that is not special rate expenditure. Cars and other excluded items do not qualify.

The 40% allowance may be relevant where:

  • The LLP cannot claim AIA
  • The AIA limit has been used
  • The expenditure is new and unused main-rate plant and machinery

The balance generally enters the main pool for later writing-down allowances.

Full expensing

Full expensing is a company relief. It is generally not available to an LLP with individual members. It should not be presented as an LLP alternative to AIA without checking the membership and tax status of the partnership.

How the relief can reduce members’ personal tax

Consider a simplified example.

An LLP acquires a commercial property for £500,000. A detailed capital allowances review identifies £60,000 of qualifying fixtures and integral features. Assume the LLP has:

  • Annual rent: £60,000
  • Interest and operating costs: £40,000
  • Profit before capital allowances: £20,000
  • Qualifying expenditure available for an AIA claim: £60,000

The calculation would be:

Item Amount
Profit before capital allowances £20,000
AIA claim (£60,000)
Tax-adjusted LLP result (£40,000)

The first £20,000 of the allowance shelters the profit for the year. The remaining £40,000 creates a loss.

That loss is not automatically available for each member to offset against salary, investment income or other personal income. The treatment depends on whether the LLP is carrying on a property business or a trade, the member’s capital contribution, participation and the specific loss-relief rules.

A second illustration shows the potential tax effect where the LLP has a higher taxable profit:

Item Amount
Profit before capital allowances £100,000
Capital allowances claimed (£60,000)
Remaining taxable profit £40,000

If a member is able to use a £60,000 reduction at a marginal Income Tax rate of 40%, the indicative tax reduction is £24,000. This is an illustration, not a guaranteed saving. The actual result depends on the member’s tax band, profit allocation, other income, National Insurance position, the LLP agreement and the availability of loss relief.

Capital allowances reduce taxable profit. They do not reduce the purchase price, repay borrowing or create a direct cash payment from HMRC.

The shop-and-upper split

Mixed-use property requires a documented allocation between the commercial and residential elements.

For example:

  • Purchase price: £500,000
  • Qualifying commercial fixtures: £60,000
  • Residential fixtures: £20,000, excluded from the plant and machinery claim

The £60,000 commercial figure should be supported by an appropriate survey, invoices, contracts, valuation methodology and property plans. The allocation should be reasonable and capable of being explained to HMRC.

When buying a second-hand commercial property, the buyer should investigate whether the seller has pooled qualifying fixtures. The parties may need a Section 198 election to agree the disposal value of fixtures for capital allowances purposes.

Without the required history and election, the buyer’s ability to claim may be restricted. Capital allowances due diligence should therefore begin before exchange of contracts, not after completion.

Losses and restrictions

Capital allowances may create or increase an LLP loss. The use of that loss depends on the nature of the activity.

For a property business, losses will commonly be carried forward against future profits of the same property business, subject to the applicable rules. Where a qualifying trade allows sideways loss relief, restrictions may apply. These can include limits linked to the member’s capital contribution and other statutory conditions.

An LLP member should not assume that a capital allowances loss can be used against employment income or other personal income. The member’s involvement, capital at risk, profit allocation and the nature of the LLP activity all require review.

The LLP agreement should also be checked. A tax allocation that differs from the commercial profit-sharing arrangement may require separate analysis and can create legal, tax and accounting issues.

Commercial substance and anti-avoidance

Capital allowances are legitimate reliefs when they are claimed for qualifying expenditure incurred in a genuine commercial activity. They should not be used to support artificial arrangements.

HMRC’s Spotlight 63a warns about hybrid partnership arrangements involving corporate members and indemnities. HMRC states that arrangements promoted to redirect property profits, bypass finance-cost restrictions or reduce personal tax may be challenged.

Potential consequences include:

  • Additional tax
  • Interest
  • Penalties
  • SDLT liabilities
  • Professional fees
  • Costs associated with unwinding the arrangement

An LLP should have a clear commercial purpose, genuine business activity and properly documented rights and obligations. If an arrangement depends mainly on a tax result that appears disproportionate to the commercial activity, obtain independent advice before proceeding.

Exit planning and balancing charges

Capital allowances are often timing reliefs rather than permanent exemptions.

If an asset on which allowances were claimed is sold, transferred or removed from business use, a disposal value may reduce the relevant pool. If the disposal value exceeds the remaining pool, a balancing charge may increase taxable profit.

A balancing charge can arise even where AIA produced a 100% deduction and the pool has a nil balance. The disposal value may then be brought back into the tax computation.

SBA has separate rules. When a qualifying structure is sold, the buyer may continue claiming the remaining allowance if the conditions are met. The seller may also need to consider the effect of claimed SBA on the calculation of a capital gain or loss.

Exit strategy, refinancing and future changes of use should be considered when the initial claim is prepared.

Realty Packaging’s due diligence approach

Capital allowances form only one part of a commercial property review. Realty Packaging assesses opportunities through four core areas:

  1. Lease : review lease terms, rent, break rights, repair obligations and landlord matters.
  2. Planning : confirm lawful use, consents and development potential.
  3. Building condition : identify physical defects, future expenditure and maintenance obligations.
  4. Operational compliance : review fire safety, access, services and other operational requirements.

Capital allowances do not cure a poor lease, defective planning position or unresolved building issue. A tax-efficient property investment still requires full commercial property due diligence.
