What Records Are Essential For Commercial Property Sales in Milton Keynes?

Acquisition records that form the starting point of every computation

The single most important set of documents is the original purchase paperwork. The completion statement from the solicitor who acted on the acquisition, the stamped transfer, the Land Registry title documents and any valuation obtained at the time all establish the base cost for capital gains tax purposes. Where the property was bought before 31 March 1982 the March 1982 market value may still be relevant for older holdings, so any contemporaneous valuation or professional appraisal should be retained even if it feels historic.

Stamp Duty Land Tax (or its predecessor stamp duty) paid on acquisition forms part of the allowable expenditure. Keep the SDLT return and the HMRC certificate. In practice I still see clients who discarded these years ago and then have to reconstruct the figures from bank statements or solicitors’ ledgers when HMRC asks for evidence. That reconstruction is possible but time-consuming and always carries a risk of understatement.

Improvement and enhancement expenditure

Any capital work that enhances the value of the property – a new roof, structural alterations, the installation of air-conditioning that becomes a fixture, or the creation of additional floor space – must be supported by invoices, contracts and, ideally, photographs or architects’ drawings. HMRC will accept genuine enhancement expenditure as an addition to the base cost, but only if the work is capital in nature and not merely repair. Distinguishing the two is often the point at which enquiries arise.

I recently advised a client who had spent roughly £180,000 over twelve years on successive upgrades to a small industrial unit near the M1. Because every invoice had been filed and cross-referenced to the relevant planning permission or building-control certificate, we were able to add the full amount to the base cost. Without that paper trail the same expenditure would have been challenged and a larger gain would have arisen.

Capital allowances history and the fixtures problem

Commercial property almost always contains plant and machinery fixtures – lighting, heating systems, sanitary fittings, security equipment and, in more modern buildings, data cabling and renewable-energy installations. If capital allowances have been claimed on those fixtures during ownership, the seller must deal carefully with the disposal value. In most cases the commercial preference is to agree a section 198 election under the Capital Allowances Act 2001 fixing the disposal value of the fixtures at a low figure, commonly £1 for each pool. That election must be made within two years of the sale and both parties must sign it. Without the election the disposal value defaults to a just and reasonable apportionment of the sale price, which can trigger an unexpected balancing charge.

Structures and Buildings Allowance (SBA) claims require a different piece of paperwork: the allowance statement. When the relevant interest is sold the seller must pass a copy of that statement to the buyer. The statement identifies the building, the date of the earliest written construction contract, the amount of qualifying expenditure and the date the building was first brought into non-residential use. Failure to supply it does not prevent the sale, but it does prevent the buyer from claiming the remaining allowances and can sour the commercial relationship at a late stage.

VAT option to tax and Transfer of a Going Concern considerations

Expert tax accountants in Milton Keynes have been the subject of an option to tax. The seller must be able to produce the HMRC acknowledgement of that option, or at least evidence that the option was validly made. Buyers’ solicitors will ask for it as a matter of course. If the sale is intended to be treated as a Transfer of a Going Concern (TOGC) for VAT purposes, additional records become essential: evidence that the property was let or used as part of a business, that the buyer intends to continue that business, and that both parties are VAT-registered (or will be). A missing option-to-tax acknowledgement can delay completion by weeks while HMRC is asked to re-issue confirmation.

Lease documentation and tenant history

Where the property is let, the full suite of leases, licences to assign, rent-review memoranda and service-charge accounts must be available. These documents do not directly enter the capital gains computation, yet they affect the commercial value and, in some cases, the availability of Business Asset Disposal Relief if the property has been used in a trade rather than held as a pure investment. Details of any periods of vacancy or non-qualifying use can also matter if the seller is hoping to argue that the property formed part of a larger trading business.

Practical client scenario from the Milton Keynes market

A typical situation I encounter involves a limited company that bought a multi-let office building in the early 2000s. Over the years the company claimed plant and machinery allowances on successive fit-outs, claimed SBA on a later extension, and opted to tax the property. When the directors decide to sell, the solicitor’s pre-contract enquiries (the Commercial Property Standard Enquiries) ask detailed questions about capital allowances, VAT and any previous elections. If the company’s accountant has kept a running capital-allowances schedule, the section 198 elections, the SBA allowance statement and the option-to-tax acknowledgement, the replies can be completed quickly and the tax position on sale can be modelled with confidence. Where those records have been scattered across different advisers or lost in office moves, the sale process slows and the risk of an incorrect tax return rises sharply.

Table of key record categories and typical retention periods

The table above reflects HMRC’s normal expectations under the Taxes Management Act and the Companies Act record-keeping rules. In practice I advise clients to keep the core acquisition and capital-allowances files permanently; storage costs are trivial compared with the cost of reconstructing figures under enquiry.

How long records must be kept and why the period matters

For individuals the statutory period is generally the later of one year after the 31 January Self Assessment deadline or the end of any enquiry. For companies the Corporation Tax self-assessment rules require records to be retained for six years from the end of the accounting period. Capital gains records should be kept for the same period after the year of disposal. Where an enquiry is opened the clock stops, so the practical advice is never to destroy the original file while there remains any realistic possibility of HMRC questions.

In the second part of this discussion I will turn to the records that become critical at the moment of sale itself, the interaction between capital allowances and the capital gains base cost, the particular issues that arise when the seller is non-resident or a pension scheme, and the practical steps that should be taken in the weeks leading up to exchange and completion to ensure that the tax return can be prepared accurately and defended if necessary.

Disposal documentation and the calculation of the chargeable gain

Once a buyer is identified and heads of terms are agreed, the focus shifts to the documents that will feed directly into the capital gains computation. The sale contract, any side letters dealing with fixtures or capital allowances, the final completion statement and any post-completion adjustments all form part of the evidence of the disposal proceeds. Where the consideration includes deferred payments, overage or a requirement for the buyer to assume existing liabilities, those elements must be valued and included at the correct amount. HMRC expects the full amount of consideration, not merely the cash that changes hands on completion day.

For properties in Milton Keynes that have been held for many years, an independent valuation at the date of disposal is often sensible even if not strictly required. It provides a contemporaneous record of market value and can be invaluable if HMRC later questions whether the transaction was at arm’s length, particularly where the buyer is connected or the sale forms part of a larger corporate reorganisation.

The interaction between capital allowances and the capital gains base cost

One of the most frequently overlooked points in commercial property sales is the effect of previous capital-allowances claims on the capital gains computation. Under section 41 of the Taxation of Chargeable Gains Act 1992, expenditure that has qualified for capital allowances is excluded from the base cost to the extent that allowances have been or could have been claimed. In practical terms this means that the more generous the plant and machinery or SBA claims made during ownership, the higher the eventual chargeable gain can become.

I have seen cases where a seller claimed substantial allowances over a decade and then discovered, only after exchange, that the base cost for capital gains purposes had been reduced by a corresponding amount. The resulting tax bill was larger than expected. The solution is to maintain a running reconciliation between the capital-allowances pools and the capital gains base cost from the outset. When the property is sold that reconciliation allows the tax adviser to calculate both the balancing charge (or allowance) and the capital gain with precision.

Section 198 elections and the commercial negotiation

As noted earlier, the section 198 election is the usual mechanism for fixing the disposal value of fixtures. The election must be joint and must be made within two years of the disposal. In practice the negotiation often takes place before exchange, because the buyer will want certainty about the allowances available going forward. The election can cover some or all of the fixtures, and the parties are free to agree any figure between £1 and the original cost (subject to the overall just-and-reasonable limit). Sellers generally prefer a low figure to minimise any balancing charge; buyers prefer a higher figure to maximise future writing-down allowances. The records that support the negotiation are the original invoices, any previous elections with earlier owners, and a current capital-allowances report prepared by a specialist surveyor or accountant.

Special situations: non-residents, companies and pension schemes

Where the seller is non-UK resident, the non-resident capital gains tax rules apply to direct disposals of UK commercial property. The base cost for properties held at 5 April 2019 is generally the market value at that date unless an election is made to use the original cost. Records of the April 2019 valuation, together with any subsequent enhancement expenditure, become essential. Non-resident sellers must also file a non-resident capital gains tax return within 60 days of completion and pay any tax due, so the records must be in a state that allows rapid calculation.

Company sellers account for the gain within their corporation-tax computation rather than under capital gains tax. The same underlying records are required, but the rate of tax will be the prevailing corporation-tax rate (19 per cent, 25 per cent or the marginal rate depending on the size of the company’s profits). Pension schemes, including SSASs that hold commercial property, are generally exempt from tax on gains provided the property is held as an investment and certain conditions are met. Even so, the scheme administrators still need full acquisition and disposal records to demonstrate that the exemption applies and to support any later HMRC review.

Practical steps in the weeks before exchange

In the period leading up to exchange I recommend that clients assemble a dedicated sale file containing:

• the original acquisition completion statement and title documents

• a full capital-allowances history including any section 198 elections already in existence

• the current SBA allowance statement

• the VAT option-to-tax acknowledgement

• copies of all leases and licences

• invoices and contracts for every significant improvement

• any valuations obtained during ownership

That file should be reviewed by both the tax adviser and the conveyancing solicitor. Any gaps can then be addressed before the buyer’s enquiries arrive. Where records are incomplete it is sometimes possible to reconstruct them from bank statements, old tax computations or Land Registry documents, but the process is never as reliable as having the originals.

Reporting the disposal and retaining evidence after completion

After completion the seller must report the disposal on the appropriate tax return – Self Assessment for individuals, the company tax return for corporate sellers, or the non-resident capital gains tax return where relevant. The computation itself should be supported by the records already described. HMRC can open an enquiry into the return for the normal statutory period, so the entire file should be retained for at least five years after the filing deadline for individuals and six years for companies. Electronic storage is acceptable provided the documents remain legible and can be produced promptly if requested.

Common pitfalls observed in Milton Keynes practice

Over two decades I have seen the same issues recur. Clients discard old invoices believing that once the property is sold the paperwork is no longer needed. Capital-allowances elections are overlooked until after the two-year window has closed. Option-to-tax acknowledgements are lost in office moves. Enhancement expenditure is treated as revenue repair in the accounts and then cannot be added to the base cost. Each of these problems is avoidable with disciplined record-keeping from the start of ownership.

The commercial property market in Milton Keynes continues to see steady transactional activity. Sellers who treat the tax records as an integral part of the asset, rather than an afterthought, are the ones who complete cleanly, pay the correct amount of tax and move on without the lingering worry of an HMRC letter. The records themselves are not complicated; what matters is that they are complete, organised and available when the moment of disposal arrives.
