Frequently Asked Questions & Detailed Tax Guide

What is the difference between a Business Partnership and a Limited Company?

A business partnership (ordinary partnership) is a structure where two or more individuals agree to share the profits, losses, and administrative responsibilities of a business. Similar to sole traders, partners are personally liable for the debts of the partnership (joint and several liability), and profits are taxed directly as personal income. A Limited Company is a separate legal entity with limited liability for its directors and shareholders. Alternatively, a Limited Liability Partnership (LLP) combines the tax flow-through structure of a partnership with the limited liability protection of a company. The correct choice depends on how profits are shared, tax thresholds, and risk profile.

How are partnerships and Limited Companies taxed?

The core differences lie in how income is assessed by HMRC:

• Partnership: The partnership submits an informational tax return (SA800), but pays no tax directly. Instead, profits are allocated to each partner based on the partnership agreement, and each partner pays Income Tax and Class 4 National Insurance on their share via Self Assessment.
• Limited Company: Profits are taxed at 19% to 25% corporate tax. Shareholders are then taxed individually only when profits are extracted as dividends or salaries.

Step-by-Step Partnership vs. Company Comparison

Consider a business with two equal partners generating £120,000 in net profit (£60,000 share each):

Partnership Structure:

• 1. Individual profit share: £60,000.
• 2. Deduct Personal Allowance: £12,570. Taxable income: £47,430.
• 3. Income Tax: 20% on basic rate (£37,700) = £7,540; 40% on excess (£9,730) = £3,892. Total Income Tax = £11,432.
• 4. Class 4 NI (8% up to £50,270, 2% above): (£37,700 * 8%) + (£9,730 * 2%) = £3,211.20.
• 5. Total Tax per Partner: £11,432 + £3,211.20 = £14,643.20.
• 6. Combined Take-Home Pay (both partners): £120,000 – £29,286.40 = £90,713.60.

Limited Company Structure (Equal Shareholders):

• 1. Pay both directors a salary of £12,570: £25,140 total (deductible).
• 2. Taxable Corporate Profit: £120,000 – £25,140 = £94,860.
• 3. Corporation Tax (19% on first £50k, 26.5% marginal rate on excess up to £250k): (£50,000 * 19%) + (£44,860 * 26.5%) = £9,500 + £11,887.90 = £9,500 + £11,887.90 = £21,387.90.
• 4. Net Profit for Dividends: £94,860 – £21,387.90 = £73,472.10 (£36,736.05 each).
• 5. Dividend Tax per Partner (assuming basic rate): (£36,736.05 – £500 allowance) * 8.75% = £3,170.65.
• 6. Combined Take-Home Pay: £120,000 – £21,387.90 (Corp) – £6,341.30 (Div Tax) = £92,270.80.
• 7. Limited Company Benefit: **£1,557.20 extra take-home pay** plus asset protection.

Tax Expert Pro-Tips: LLPs for Professional Practices

David Vance, CTA FCA, recommends: “For professional service firms (like solicitors, doctors, or architects), a Limited Liability Partnership (LLP) is often the optimal structure. It provides full liability protection for partners, protecting personal assets from negligence claims against other partners, while avoiding the corporate tax administration and double-taxation of profit extraction. However, if partners intend to retain profits in the business to fund capital investments, a Limited Company is superior because corporate tax rates (19%-25%) are much lower than higher-rate personal tax (40%-45%).”
