Business Tax Services

Smart Business Tax Planning, Fully Compliant

Stay ahead of HMRC, claim every relief you're entitled to, and pay no more tax than you legally need to. Practical tax advice that protects your business and supports its growth.

Overview

Tax Compliance plus planning in one service.

UK business tax has become more complex with every Finance Act. Corporation tax rates, capital allowances rules, R&D scheme reform, full expensing, transfer pricing, off-payroll working and Making Tax Digital all need careful handling and forward planning to avoid costly mistakes.

Our business tax team handles the full picture: timely, accurate compliance combined with proactive advice that keeps your tax liability as low as the law allows. We work with limited companies, partnerships, LLPs and group structures across every sector, from owner-managed businesses to UK subsidiaries of international groups.

Compliance is the floor, not the ceiling

Filing the right return on time is the bare minimum. The real value comes from spotting the planning opportunities most firms miss: timing capital expenditure to maximise allowances, structuring transactions tax-efficiently, claiming reliefs your business genuinely qualifies for, and making sure director remuneration is set up the right way. We handle compliance carefully, then go further.

When tax decisions matter most

Some moments deserve specialist input. Selling shares or assets, restructuring, raising investment, expanding overseas, bringing in new shareholders, or exiting the business altogether all have major tax consequences that need planning well before the transaction. We work alongside your legal advisers to make sure the structure protects your interests and the resulting tax position is the right one for you and your shareholders.

Corporate Tax Advice FAQs

When is corporation tax due?
For most companies, corporation tax is due nine months and one day after the end of your accounting period. Companies with profits over £1.5 million pay in quarterly instalments, with the first payment due during the accounting period itself. We always confirm payment dates well in advance so there are no surprises.
Yes, R&D tax relief is one of our core specialisms. We have a dedicated team in our Portsmouth office handling R&D claims for SMEs and larger companies across the UK. The scheme has changed significantly in recent years and many firms get the technical narrative wrong, so it pays to use a specialist.
Yes. We support businesses through compliance checks, COP8 and COP9 investigations, voluntary disclosures and tribunal appeals. Early specialist input usually leads to better outcomes than trying to handle HMRC enquiries internally.
It depends on your overall income, pension position and long-term plans. The classic salary-plus-dividend approach still works for most owner-managers, but the optimal mix changes year to year as thresholds and rates shift. We review this annually.
Yes. We advise on cross-border issues including transfer pricing, permanent establishment, double taxation relief, and the UK tax position of inbound investment. For specialist jurisdictions we work alongside trusted international partners through our network.
