Taking your business into new markets – whether that’s across the UK or overseas – is a big milestone. It’s a sign that your hard work is paying off and you’re ready to grow. But with expansion comes a host of financial and tax implications that can be easy to overlook until they become problems.

At AK Tax, we regularly speak to business owners who feel overwhelmed by the complexity of growing their business from a tax point of view. Suddenly there are new registrations to think about, unfamiliar rules to follow and questions around what taxes apply where.

This blog will guide you through the most important tax considerations when expanding – both domestically and internationally – and show you how careful planning can reduce your liabilities, avoid compliance issues and help you focus on building the future of your business.

Understanding the Tax Impact of Expansion

When your business grows, your tax obligations don’t just scale up – they can change entirely. Expanding within the UK might mean adjusting how you charge VAT, restructuring your company, or investing in new equipment that affects your capital allowances.

International expansion introduces even more complexity. Many business owners are surprised to find that simply hiring someone in another country or signing contracts abroad can create a “permanent establishment”, meaning you may owe corporation tax in that country – even if you’re still based in the UK.

Before expanding, it’s crucial to assess how your operations will be affected and which taxes you might now be liable for.

Domestic Expansion: VAT and Corporate Tax Considerations

If your business is growing within the UK, it’s worth reviewing your VAT status and your corporate tax planning. Reaching new customers or opening additional locations might mean crossing the VAT threshold (currently £90,000 in taxable turnover). You may also need to adapt how you account for VAT on different products or services, particularly if you start offering digital or international sales.

On the corporation tax side, expanding can trigger new costs but also unlock opportunities. If you’re investing in infrastructure or staff, there could be tax reliefs available – more on that shortly.

Going International: What You Need to Know

Expanding beyond the UK introduces additional tax obligations that can become complex quickly – particularly around transfer pricing and double taxation.

Transfer Pricing

When UK businesses trade with a related company abroad – such as a foreign subsidiary – the transactions between them must follow transfer pricing rules. In simple terms, the prices you charge between entities must be the same as what you’d charge an unrelated business.

This prevents businesses from shifting profits to low-tax jurisdictions unfairly and most countries (including the UK) enforce this closely. You’ll need proper documentation to justify your pricing and avoid disputes with tax authorities.

Double Taxation

Without proper planning, you could end up paying tax on the same income in two countries – a situation known as double taxation. The UK has agreements with many countries to prevent this, but to benefit from these treaties, you’ll need to apply the rules correctly.

That means understanding when to claim relief, how to report your income and what steps to take to avoid being taxed twice. This is an area where professional advice really does pay off.

Reliefs and Allowances for Growing Businesses

While tax obligations increase with expansion, so do opportunities for relief. If you’re investing in your business, several government-backed schemes can help reduce your tax burden.

Capital Allowances and Full Expensing

Purchasing new equipment or machinery? You might be able to deduct the full cost from your taxable profits using capital allowances. The UK’s full expensing scheme allows companies to claim 100% of qualifying investments up front – an excellent incentive when you’re scaling operations.

R&D Tax Relief

If your expansion involves innovation – perhaps you’re developing a new product or improving internal processes – you may be eligible for Research & Development (R&D) tax relief. This scheme supports businesses working on technical or scientific projects and can lead to a lower tax bill or even a cash rebate.

Employment Incentives

Bringing on new staff as part of your growth plans? The Employment Allowance reduces your employer National Insurance contributions, while apprenticeships and training may also attract financial support.

These reliefs don’t apply to everyone – but when they do, they can make a meaningful difference to your bottom line.

Why Tax Planning is Essential During Growth

One of the biggest mistakes growing businesses make is treating tax as something to “sort out later”. The truth is, the earlier you build tax planning into your expansion plans, the smoother and more cost-effective your growth will be.

Good tax planning means you:

• Understand what costs to expect
• Stay compliant across all jurisdictions
• Avoid unexpected penalties
• Maximise opportunities to reduce your tax liability

Whether you’re changing your business structure, launching in a new region, or going global, having a tax strategy in place gives you confidence – and frees you up to focus on running your business.
