Scaling SaaS videos: key tax priorities for scaling SaaS businesses
As SaaS businesses scale, tax is rarely the first thing management focuses on. Product, growth, hiring and customers usually come first. But in practice, tax issues often build quietly in the background as the business becomes more international, more valuable and more complex.
For founders, CFOs and finance leaders, the key is making sure tax keeps pace with the way the business is growing, so early decisions do not create unnecessary cost or complexity later on.
In this short video, Ruth Brennan, Tax Partner at Moore Kingston Smith, outlines the tax priorities SaaS businesses should be focusing on as they move from early growth into more established scale-up territory. Below, we summarise the key take aways.
Managing cross-border tax costs as the business grows
Many SaaS businesses start life as UK-focused operations, but international activity often follows quickly; whether through overseas customers, remote employees, international contractors or new group entities.
Once activity crosses borders, it becomes much easier for tax costs to arise if the structure has not been thought through early enough. Common pressure points include:
- withholding tax on royalty payments for software or IP;
- funding issues, including withholding tax on cross-border interest payments and cases where not all borrowing costs end up being tax deductible;
- VAT complexity on digital services, particularly where customer location and B2B or B2C status affect the treatment.
These issues rarely appear overnight. More often, they build gradually as the commercial model evolves. Regularly reviewing how money flows through the group and how that aligns with the underlying activity can help prevent tax costs emerging unexpectedly.
Getting IP ownership and substance aligned early
In a SaaS business, a large part of the value often sits in the product and the underlying intellectual property (IP). Where that IP is owned, developed and managed matters, both from a tax perspective and when investors begin to look more closely at the group structure.
A common challenge is that the legal ownership of IP and the activity that creates and manages its value do not always sit in the same place. Simply moving legal ownership does not necessarily mean that the right to the associated income moves with it for tax purposes. Tax authorities look closely at where the real development work is happening, where key decisions are being made and who is actually controlling the important risks.
This is why it is usually much easier to think about IP location early, before significant value has built up. Once the IP is highly valuable, moving it can trigger material tax costs and the position becomes much harder to manage efficiently. Early planning can help make sure the structure is both commercially sensible and robust from a tax perspective.
Managing permanent establishment risk as teams globalise
SaaS businesses often build international capability through people before they establish formal overseas entities. While that can make commercial sense, it can also mean the business creates a taxable presence in another country earlier than expected. Tax advisers often refer to this as ‘permanent establishment risk’.
This can arise where senior decision-makers, sales teams or developers are operating overseas, even if the group does not yet have a legal entity in that country. Without active management, this can lead to unexpected corporate tax obligations and compliance requirements.
Understanding where teams are located, what decisions they are making and how customer contracts are structured is key to identifying and managing this risk.
Pressure-testing the structure before value accelerates
As SaaS businesses scale, value can increase quickly, driven by recurring revenue, customer retention and growth potential. A structure that made sense earlier in the journey may no longer be the right fit once the business is larger, more international or moving toward a transaction.
It is worth sense-checking the group structure at key points, such as:
- preparing for a significant funding round;
- expanding into new territories;
- centralising IP or commercial functions;
- planning for a future exit.
Addressing potential issues before value accelerates generally provides more flexibility and avoids tax becoming a constraint on strategic decisions later on.
Avoiding last-minute tax surprises during transactions
One of the most common challenges we see is tax issues being identified only once a transaction is already underway. At that point, options are often limited and issues can quickly become costly or delay progress.
Early reviews can help identify areas such as withholding taxes, VAT exposure, interest deductibility or cross-border compliance obligations while there is still time to address them sensibly. From an investor’s perspective, a clear and coherent tax story can also support valuation and speed up due diligence.
What should SaaS finance leaders be doing now?
While every business is different, three practical steps apply across most SaaS scale-ups:
Map where the business is really operating including people, IP, customers and cash flows;
Review whether the current structure will still work as the business grows and value increases;
Identify potential tax costs and compliance issues early, while there are still options to manage them.
Tax planning for SaaS businesses is not about complexity for its own sake. Done well, it supports growth, reduces risk and helps ensure the business is well-positioned for future investment or exit opportunities.
