BIM33190 - Stock: valuation: depreciation in stock

Depreciation in trading stock

For financial statements properly to reflect business costs they have to take account of the wearing out or other reduction in the useful economic life of fixed assets. Depreciation is a measure of this and is charged against income in arriving at the commercial profit. For tax purposes depreciation of fixed assets is a capital matter and therefore must be added back in the tax computation.

Until 2007 HMRC’S view, following principles derived from case law, accountancy and the Companies Act, was that the year in which the depreciation was to be added back was the year in which the stock was manufactured. Additional support for this view was given by the Hong Kong case of Secan Limited v CIR [2000] 74TC1. Where depreciation was included in trading stock we believed taxpayers were deducting the full amount of depreciation in their profit and loss account and were bringing in a credit representing the value of the stock on the other side of the profit and loss account. The fact that the ‘cost’ or fall in value of the fixed assets had been included as part of the value to the taxpayer of the stock carried forward did not mean that the full amount of depreciation had not been charged to the profit and loss account. Further, even if the accounts showed only the ‘net’ figure charged to profit and loss account, this was irrelevant. It was not a matter of accounting principle. Rather it is, in Lord Millet’s words, “merely a matter of presentation”.

Guidance following the decision in Secan was published in TB59 in June 2002. From that date where an adjustment to the depreciation add-back in respect of depreciation in trading stock had, unusually, been an accepted part of tax computations, taxpayers had to move to the revised basis for computing taxable profits.

HMRC v William Grant & Sons Distillers Ltd and Small (HMIT) v Mars UK Ltd [2007]

HMRC’s approach has been successfully challenged, the House of Lords finding against us in a decision dated 28 March 2007. The case involved joint appeals by Mars UK Ltd and William Grant & Sons Distillers Ltd.

The applicable accountancy

Lord Hoffman said that the applicable accounting standard for depreciation is FRS15, which replaced SSAP12 in 1999. Paragraph 16 of SSAP12 had required that the whole of the depreciation charge should be reflected in the profit and loss account. Paragraph 77 of FRS15 clarified and refined paragraph 16 of SSAP12.

Paragraph 77 requires that the depreciation charge for each period is recognised as an expense in the profit and loss account for the period unless it is permitted to be included in the carrying amount of another asset. Hoffman explains what this means by reference to the principle that the determination of profit for an accounting period requires the matching of costs with related revenues. Hoffman goes on to say:

“This fundamental principle is given effect by taking the revenue which has arisen in therelevant year and deducting from it only those costs which are attributable to those sales.These costs may have been incurred in the year in question, or they may have been incurredin earlier years and carried forward in accordance with the general principle, to be matchedwith the related sales when they occur. The costs of stocks which remain unsold at the yearend are not deducted for the purpose of computing profit in that year but are carried forwardto be matched against revenue from their sale in future years.”

Paragraph 17 of SSAP9 says that the cost of stocks includes not only the cost of purchasing the materials but also the ‘costs of conversion’. These are defined to include costs ‘specifically attributable to units of production’, including ‘production overheads’. Paragraph 20 of SSAP9 specifically provides that such overheads should include the depreciation of assets ‘which relate to production’.

Both Mars and Grant prepared their accounts in accordance with these standards. They divided the depreciation which occurred during the year or was carried in the opening stock into two parts:

  • the first part was depreciation in fixed assets which related to the production of goods sold during the year, and
  • the second part was the depreciation in fixed assets which related to the production of unsold stocks.

Both Mars and Grant deducted the first part depreciation from the year’s revenue and carried forward the second part as part of the cost of unsold stock. Expert accountancy evidence on both sides agreed that:

  • this was the way the computations had been made, and
  • that the resulting statement of profits was in accordance with the standards, and
  • gave a true and fair view.

On this basis Hoffman considered it “plain and obvious” that only the first part depreciation had been deducted in arriving at the profit for the year.

The tax effect resulting from this accounting analysis is that ICTA88/S74(1)(f) does not require the second part of depreciation to be added back. It will be added back when the stock is disposed of and the depreciation is deducted in arriving at the profit for the year of the disposal.

First accounts and computations submitted after the date of the House of Lords decision

Businesses should use the method approved by the House of Lords in the first computations accompanying accounts prepared and submitted after the date of the decision.

Unusually, there may be some instances when the accounts themselves treat the depreciation of assets used in the manufacture of stock in the way outlined under “The applicable accountancy” for the first time after the House of Lords decision. If so please contact CT & VAT or speak to your HMRC compliance accountant to ensure that the accounts before and after the change comply with generally accepted accounting practice.

Adjustment on change of basis

Where the business was trading in years prior to the date of the decision you will need to consider the ’change of basis‘ legislation where there is a move from computations prepared following HMRC’s earlier view to those following the House of Lords’ view. This will apply where returns are filed using the new approach for the first time after the House of Lords’ decision or where there are earlier open years

If items of stock are held over more than one accounting period end the computations should show an adjustment to take into account a change of basis within FA2002/S64 and Schedule 22 (or on decided principles in earlier years) and ITTOIA 2005 Chapter 17 (Section 226 and following). This is sometimes referred to as a ’catch up‘ adjustment – it will be a negative or positive (in some more unusual circumstances) adjustment arising from a computational change from adding back depreciation on manufacture of stock to adding it back on disposal. In very simple terms you will need to consider the figure for depreciation that was added back in earlier years but relates to stock that has not yet been sold. See BIM 34000 and following for further information. The accounts will not show a prior period adjustment because it is only in relation to the computations that changes are required, not the accounts themselves.

Error or mistake

You should reject ‘Error or Mistake’ claims seeking to rely on this decision. This is on the basis that computations submitted and agreed in accordance with the position set out in earlier guidance were prepared in accordance with the then ‘prevailing practice’ – TMA70/S33(2A) refers. See SACM12000 and following for further information.

Practical matters

You will need to consider whether the business has in place appropriate mechanisms to ensure that depreciation is added back in the computation for each year/period of disposal of the stock in question.

Where there are only a small number of relatively large items in stock businesses will find it easier to track the depreciation within stock and so ensure that on the disposal of the stock in question the relevant depreciation is correctly included in the tax computation.

Where the stock comprises a very large number of individual items each of relatively modest value, businesses may find the record keeping requirements to be burdensome when the new depreciation in stock approach is adopted. They must however follow the method approved by the House of Lords and cannot use the former method.
