Why Your Accountant Might Be Missing Capital Allowances (And Why That’s Completely Normal)

When business owners hear about capital allowances, one of the first responses is often:

“Surely my accountant has already claimed everything?”

It is a perfectly reasonable assumption.

After all, your accountant prepares your accounts, files your tax returns and advises on a wide range of financial matters. Most business owners naturally assume that any available tax relief will already have been identified.

However, when it comes to commercial property and capital allowances, the reality is often more complicated.

In our experience, many commercial property owners, hotel operators, restaurant groups and investors are sitting on substantial unclaimed tax relief despite having excellent accountants.

The reason is not that their accountants have done anything wrong. Rather, capital allowances often require a very different set of skills from those traditionally associated with accountancy.

Capital Allowances Are Not Just a Tax Exercise

Many people think of capital allowances as purely a tax issue.

In reality, they sit at the intersection of tax, construction, property and valuation.

Whilst an accountant can clearly identify assets such as vehicles, computers or machinery from an asset register, commercial property presents a very different challenge.

A modern commercial building may contain hundreds of qualifying assets hidden within wider construction costs.

These assets are rarely listed separately in the accounting records.

As a result, identifying them often requires a detailed understanding of how buildings are constructed and how expenditure should be categorised for tax purposes.

The Challenge of Commercial Property

Imagine a company spends £2 million refurbishing a hotel.

The accounting records may simply contain entries such as:

  • Building works.
  • Mechanical and electrical installations.
  • Contractor costs.
  • Refurbishment expenditure.

Unfortunately, these descriptions tell us very little about what actually qualifies for capital allowances.

Hidden within those costs may be:

  • Air conditioning systems.
  • Electrical infrastructure.
  • Fire alarm systems.
  • Security installations.
  • Heating systems.
  • Specialist lighting.
  • Plumbing installations.
  • Lifts and escalators.

Without analysing the underlying project in detail, these opportunities can easily be overlooked.

Why Quantity Surveyors Are Often Involved

This is one of the reasons specialist capital allowance firms frequently utilise quantity surveyors.

Quantity surveyors understand how buildings are designed, constructed and costed.

They can analyse construction projects and identify qualifying expenditure that may not be visible from accounting records alone.

In many cases, a detailed property review can uncover significant qualifying expenditure that would otherwise remain hidden.

This is not something most accountants are expected to do as part of a standard compliance engagement.

Accountants and Capital Allowances: A Different Role

Most accountants focus on preparing accounts and tax returns using information provided by their clients.

Where capital allowance schedules already exist, they will generally ensure that the claims are included correctly within the tax computation.

However, identifying previously unclaimed allowances within a commercial property often requires a separate exercise altogether.

This may involve:

  • Reviewing property purchase contracts.
  • Analysing construction costs.
  • Examining historic refurbishments.
  • Conducting site inspections.
  • Preparing detailed valuation reports.

These activities typically fall outside the scope of routine accountancy work.

Why This Matters More Than Ever

Commercial property has become increasingly sophisticated.

Modern buildings often contain extensive mechanical and electrical systems, energy-efficient technologies and specialist installations.

As a result, the proportion of qualifying expenditure within many buildings has increased significantly.

At the same time, corporation tax rates have risen and businesses are increasingly focused on preserving cash flow.

This means that overlooking capital allowances can have a much greater financial impact than many business owners realise.

The Most Common Situations We Encounter

Many of the opportunities we identify arise from situations such as:

A commercial property acquired several years ago where no specialist capital allowance review was undertaken.

A hotel refurbishment project where allowances were claimed on obvious equipment but not on embedded fixtures.

An office fit-out where substantial mechanical and electrical expenditure was grouped together within general construction costs.

A property portfolio where capital allowances have never been reviewed on a building-by-building basis.

In each case, valuable tax relief may remain available despite previous tax returns having been submitted correctly.

Capital Allowances Are Often a Team Effort

The most successful outcomes usually occur when accountants and capital allowance specialists work together.

The accountant understands the wider tax position of the client and ensures that any relief is reflected correctly within the tax computation.

The capital allowance specialist identifies qualifying expenditure and prepares the technical analysis required to support the claim.

Rather than replacing the accountant, specialist reviews typically complement the existing advisory relationship.

This collaborative approach often delivers the best results for clients.

Why Businesses Should Review Historic Expenditure

One of the biggest misconceptions is that missed capital allowances can never be recovered.

In many cases, historic expenditure can still be reviewed and previously unclaimed allowances identified.

This can apply to:

  • Commercial property acquisitions.
  • Refurbishments.
  • Extensions.
  • Conversions.
  • Fit-out projects.

Until a specialist review has been undertaken, it is often impossible to know whether valuable relief remains available.

The Cost of Assuming Everything Has Been Claimed

Perhaps the biggest risk is simply assuming that there is nothing left to find.

We regularly encounter businesses that believed all available relief had already been claimed, only to discover substantial opportunities hidden within historic property expenditure.

The larger and more complex the property, the greater the likelihood that specialist analysis may uncover additional relief.

This is particularly common within hotels, care homes, office buildings, industrial premises and other commercial properties with significant fit-out costs.

Final Thoughts

Most accountants do an excellent job of ensuring that capital allowance claims already identified are reflected correctly within tax returns.

However, identifying capital allowances within commercial property often requires a completely different skill set involving tax legislation, construction knowledge, valuation expertise and detailed property analysis.

This is why specialist reviews can add significant value, even where a business has long-standing professional advisers.

At CapexOwl, we work closely with accountants, solicitors, property investors and business owners to identify capital allowance opportunities that may otherwise remain hidden. Our specialist team combines tax expertise with surveying knowledge to help ensure that no qualifying expenditure is overlooked.

If you own commercial property and have never undertaken a specialist capital allowance review, we would be delighted to discuss whether additional tax relief may be available.
