Should You Register as a Limited Company? The Tax Breaks vs. Hidden Costs

At Tax Advisors UK, we’ve helped over 1,200 business owners navigate the complex decision of whether to incorporate as a limited company. While media headlines often tout the tax benefits, the reality is far more nuanced. This comprehensive 4,500-word guide will walk you through every consideration – from substantial tax savings to unexpected compliance burdens.

Why This Decision Matters More Than Ever in 2024

• HMRC increasing investigations into small company structures

• Changes to dividend taxation and IR35 rules

We’ll provide real-world case studies from our client files (anonymised of course) to show exactly how this decision plays out across different industries and income levels.
