Think of a number, multiply it by three, add one, multiply this by three, add the number you first thought of, take away three, divide by ten, and the answer is …
Surprising results can emerge from a multi-step formula.
The patent box consultation issued by HM Treasury & HMRC in June has a ‘three step model’ to determine how much of a company’s profits will be ‘patent box’ profits.
The complexity makes it difficult to identify factors that will increase and those that will decrease the amount of profits in the box.
Condensing the three step model to a formula allows us to more easily spot the practical effects of the proposal and implications for companies seeking to benefit from this proposed tax relief.
The three step model can be re-expressed as:
Amount in patent box = (p – 0.15e) x |
r | x | q |
r+b | q+o |
where:
In narrative form:
The formula makes evident the items that cause reductions in the amount of profits in the patent box.
With the 15% reduction for certain trading costs, a company that spends to develop and expand its business will suffer a greater reduction than a company with the same taxable profit that does not incur such expenses.
Also, companies that spend on promotion of their products will have lower patent box profits.
And these two restrictions compound, leading to some doubling of the reduction.
The compounding effect is evident in the worked examples in the consultation paper.
In the simple example, Example A on page 35 of the paper, 70% of the company’s turnover is from patented products and the company has a trading profit of £225.
However the calculated amount in the patent box is £44 – much lower that the straight proportion by reference to turnover, which would be £158.
The hidden surprising aspect concerns entertaining and other disallowable costs.
The consultation proposes using tax adjusted figures.
Entertaining expenditure is not tax allowable and hence the patent box will effectively give tax relief for a part of companies’ entertaining expense.
To illustrate, let’s use Example A in the consultation paper.
Suppose that the £75 of marketing expenditure in the example was disallowable entertaining.
Reworking the patent box calculation would produce a patent box profit of £137 rather than £44, an increase of £93 of profits in the box.
If we assume that the year in question is after the patent box transition period, and assuming a corporation tax rate of 23%, its entertaining disallowance is in effect reduced from £75 to £22 (the patent box gives a computational deduction of 13/23 of the amount in the box; so an additional £93 in the box produces a computational deduction of £53).
Is this intended?
On the bigger picture, do these proposals align with the government’s desire for tax simplification? Should the Office for Tax Simplification be asked to review these legislative provisions before enactment? It gives the appearance of two steps forward, one back; the OTS simplify one area, only for complexity to be added elsewhere.
I would suggest that the complexity of the ‘three step model’, and what I suspect are unintended side effects, not to mention the relief that will actually be delivered is much less than businesses are expecting will require substantial revision of the proposals.
This would not be the first occasion that far too complex rules are simplified – recall the initial worldwide debt cap proposals.
Another aside on the maths and for those with a long enough memory is that the patent box will be delivered in the same way as pre-1987 chargeable gains of companies were taxed at a lower rate.
There will not actually be a patent box with a 10% rate – rather there will be a reduction to taxable profits in respect of the patent profits.
The answer to the number puzzle should be the number you first thought of.
The consultation paper is available on HM Treasury's website.
