If you’re an investor, the tax landscape you’ve known is changing. New rules are redrawing the borders on everything from selling a business to investing in global funds. It can feel complex, but think of this as your quick guide to the new terrain—what’s shifted, and what it means for your money.
Chapter 1: The Global Tax (That Isn’t Yours, But Still Affects You)
First, let’s talk about the “Pillar 2 Top-Up Tax.” It sounds technical, and it is. This is a new global rule for corporate giants—specifically, multinationals with revenues over €750 million.
Here’s the key takeaway: As an individual investor, you will not see this tax on your personal bill.

However, in our connected financial world, no change happens in a vacuum. If you own shares in large multinational companies or have investments in private equity funds, you might feel the ripple effects. These companies are now likely to face higher effective tax rates. In practice, this could mean:
- Slightly subdued growth or dividends: More tax paid by a company can mean less profit left to reinvest or distribute to shareholders.
- Increased complexity: The burden of new reporting and compliance may influence how these companies and funds operate.
So, while it’s not a direct hit to your wallet, it’s a new headwind for some of the world’s largest players, and that can influence your portfolio’s performance.
Chapter 2: The Clock is Ticking on Your Exit Strategy
This is where the changes get personal. If you’ve ever planned to sell a business or a significant stake in one, your timing just became much more important.
The government is making two key moves:
- Business Asset Disposal Relief (BADR) is Getting More Expensive
This relief, which offers a lower tax rate on qualifying business sales, is seeing its rate climb.- From April 2025, the rate jumps from 10% to 14%.
- From April 2026, it climbs again to 18%.
- A New Cost for Fund Managers (That Could Trickle Down)
The tax treatment of “carried interest”—the share of profits that fund managers in private equity receive—is also being overhauled.- From April 2025, it will be taxed at a flat rate of 32%.
- Then, from April 2026, the government plans to reclassify it entirely as income, subject to even higher Income Tax and National Insurance rates.
What This Means for Your Next Move
So, what’s the story for you?
- Timing is Everything: If a business or asset sale is on your horizon in the next few years, the decision of when to sell now carries significant tax consequences.
- Look at the Fine Print: For those invested in private equity or funds, it’s a good time to understand how these changes might impact your fund’s strategy and economics.
- Plan, Don’t Panic: These changes are not emergencies, but they are deadlines. Proactive planning is your most powerful tool.
The Bottom Line
The UK’s tax rules are evolving to keep pace with the global economy. While the Pillar 2 tax operates in the background, the increases to capital gains are a direct signal: the cost of cashing in your success is rising. By understanding this new map now, you can plot a smarter course for your financial future.
