I've written previously about the problem that some startups can encounter when they purchase IP with a view to developing it to sell in the form of licence or royalty fee income (most typically, software).
I won't rehash the technical rules here (see below), suffice to say that this set-up does not always 'play nicely' with the SEIS and/or EIS tax reliefs.
I recently advised on this matter with a startup company who had suffered this exact problem and received a knock-back from HMRC on their SEIS advance assurance application.
The company was a software development University spin-out and the Founders were denied the advance assurance on the basis of the excluded activities test.
Why does this matter?
If a company's business is substantially (read: > 20%) comprising activities that are defined as 'excluded' then the company cannot qualify under SEIS / EIS.
Many Founders are unaware that the receipt of licence fee income is an excluded activity.
And what is 99% of software development businesses' revenue income made up of?
Yes, you guessed it, licence income.
Here's the solution
It's not all bad news. There is a solution.
Deeper within the rules we find a carve-out exemption that states:
This makes sense as this excluded activity is designed to prevent patent trolls from claiming the relief for investors and then passively collecting royalty/licence fee income. It is not meant to catch genuine trading software companies.
But there's a catch...
In the case of Uni spin-out, the software under development had  been purchased from the Uni. So it can't have created it from scratch. Now it had to rely on proving that it had created the greater part of the value in the software IP...
Not so easy if you purchase the IP for say £100k. It'll take time and funding (chicken & egg: as you're trying to secure funding for the S-EIS) to demonstrate that you've created the greater part of the value in this case.
The founders ultimately got around this nail-biting hitch by restructuring the deal. Essentially purchasing the IP for a nominal sum in this case. The revised structure was ultimately accepted by HMRC.
This case really goes to show the value of the SEIS/EIS advance assurance process as on all (other) accounts, the founders were assured by those around them (myself excluded, as I didn't advise on the original application!) that they needn't worry as SEIS eligibility and consequent HMRC SEIS assurance would be a 'slam-dunk'.
Yikes, that could have been costly...
