Expert Tax Support for High Earners and Complex Finances
If you’re a high earner or have additional income outside of employment, your tax affairs can quickly become complex. At MJ Kane, we provide expert support to ensure everything is reported accurately and efficiently. Whether it’s dividends, investments, property income, or overseas earnings, we’ll make sure you stay compliant with HMRC and don’t pay more tax than necessary.
We’ll also advise on tax-efficient strategies tailored to your situation, from using allowances and reliefs to planning for future liabilities. Our clear, proactive approach means you’ll always know where you stand, avoid unexpected bills, and have confidence that your finances are in safe hands.
What Counts as Additional Income?
Additional income can include dividends, rental income, freelance work, investments, and overseas earnings. We’ll ensure all sources are reported correctly.
Are There Extra Rules for High Earners?
Yes — once your income passes certain thresholds, allowances are reduced, and higher tax rates apply. We’ll guide you through the rules and plan ahead.
How Can I Reduce My Tax Liability?
We identify legitimate reliefs and allowances to lower your bill, from pension contributions to charitable donations and investment reliefs.
Can You Help With International Income?
Absolutely — we provide advice on overseas income, double taxation rules, and HMRC compliance for income earned abroad.
