Reducing corporation tax due on patent income.
The patent box regime applies a reduced rate of corporation tax to profits attributable to qualifying patents and similar intellectual property (IP). Unincorporated businesses can’t qualify for the patent box.
The patent box tax rate has gradually been reduced to 10% since the introduction of the regime in 2013 (see table).
To benefit from this reduced rate, your company must:
- hold a qualifying patent or other qualifying IP
- receive income relating to that patent or IP
- elect into the regime.
Qualifying patents or IP
Your company must own, or hold an exclusive licence to use, one or more patents issued by the UK Intellectual Property Office, European Patent Office or any of these countries:
Your company can also qualify for the patent box regime if it holds any of the following:
- patents that would have been granted but for a prohibition on publication on the grounds of national security or public safety (such as for nuclear fuel)
- UK and European Commission plant breeders’ rights
- regulatory data protection granted in respect of medicinal, veterinary and plant protection products
- marketing exclusivity granted to orphan status medicines and medicines for paediatric use
- supplementary protection certificates.
What is IP income?
Profits from the company creating or developing the patented invention, or from a product incorporating the patented item, qualify for the patent box regime.
Where the patented device is an essential component within a larger product, the income from that bigger product falls within the ‘gross income’ definition for the patent box regime.
Profits from holding patents as investments do not qualify and are taxed at the normal rate of corporation tax, which is 19% in 2017/18.
A patented cartridge delivers a measured amount of a drug according to the weight and blood sugar levels of a patient.
It is designed to be inserted in medical monitoring device and, once installed, not to be removed until empty, at which point it will be replaced.
The patented cartridge is regarded as incorporated in the medical monitoring device.
Income from the sale of that device including the cartridge (whether the cartridge is installed or included separately in the box with the device part of a single package) can therefore qualify as relevant IP income, even if the company does not hold a patent over the device itself.
You may wish to examine carefully what IP your company owns to assess whether it would be worthwhile seeking new patents for components in order to bring the related income from the entire product within the patent box regime.
Applying for a patent is not necessarily an expensive process.
Your company can’t benefit immediately from the patent box on profits from items pending patent approval.
However, the benefit from that patent pending can be rolled-up for up to six years (see step five of the calculation section).
To do this, you calculate what the relevant IP profits of the trade (RP) would have been had the patent been granted already.
These amounts of RP are aggregated over a period of up to six years ending with the grant of the patent.
For the year the patent is granted, add that aggregated total of RP to the relevant IP profits for the year and apply the patent box deduction on the total relevant IP profits.
The calculation of profits which are subject to the patent box regime is not simple, but can be broken down into six steps:
Identify how much of the company’s total gross income includes relevant IP income (RIPI), which is broadly income derived from its qualifying patents and from items incorporating patented components. RIPI can be:
- sales income
- worldwide licence fee or royalties
- compensation including damages
- insurance proceeds.
Isolate the amount of net profits which relate to RIPI by either:
- apportioning the total tax-adjusted profits according to the ratio of RIPI to total gross income
- allocating all expenses on a just and reasonable basis to the two ‘streams’ of income (RIPI and non-qualifying income) to arrive at an appropriate profit derived from the RIPI stream.
Remove 10% of certain specified tax-deductible costs from the profits derived from the previous step.
This leaves an amount called qualifying residual profit (QRP). The specified costs include those relating to personnel, premises, plant and machinery or miscellaneous services.
R&D-related costs are not part of this specified list.
Assess whether the QRP from step three is more than £3 million or not.
If the QRP doesn’t exceed £3 million, the company can elect for the small claims treatment. Under this method remove 25% of QRP as a deemed marketing return, leaving the remaining 75% (up to a maximum £1 million) as the relevant IP profits (RP) which is inside the patent box.
If the QRP is more than £3 million, or the company has not elected for the small claims treatment, remove a return on marketing assets used to derive RIPI by deducting a notional marketing royalty for use of the assets.
Where patents have been granted during the year, the RP for up to six earlier years in relation to periods during which those patents were awaiting approval is added at this stage.
The figure of RP from step four and step five used to calculate the appropriate amount of the deduction from the profits of the trade which gives effect to the lower rate of corporation tax (see table).
Using the overall ratio of RIPI to total gross income, as required by step two in the calculation, may work to the company’s disadvantage where the non-IP income produces little profit.
In which case the company may opt for a streaming method, where costs and revenues are allocated on a patent-by-patent or product-by-product basis.
Streaming is compulsory for new entrants to the patent box regime from 1 July 2016 and for all eligible companies from 1 July 2021.
From 1 April 2017, the streaming rules are amended where R&D is undertaken collaboratively by two or more companies under a cost sharing arrangement.
The regime’s benefit is therefore restricted where R&D activity is subcontracted to connected parties or where IP rights are acquired.
The election for patent box can only apply to accounting periods beginning on or after 1 April 2013.
The election must be made within two years of the end of the first accounting period it will apply to and remains in place until it is revoked.
In practice, the election is made as part of the corporation tax computation or by a separate written notice to HMRC.
A company may opt out of the patent box regime by revoking the election in writing, specifying the first accounting period for which the vocation is to take effect.
Once the company has opted out of patent box, it can’t elect back in again for at least five years.
