Business Taxation and Financial Obligations

Business Law and Practice > Business Taxation and Financial Obligations

Most SQE1 candidates miss the same tax trap: they assume a partnership pays corporation tax. Wrong. And that mistake costs them marks when a scenario asks whether to incorporate. This guide covers corporation tax, double taxation, VAT thresholds, capital gains, and the tax-efficiency decisions that will appear in your exam—and the landmines that separate top scorers from the rest.

What is Business Taxation and Financial Obligations in SQE1?

Business taxation law governs how different business structures (companies, partnerships, sole traders, LLPs) are taxed and what financial obligations they must meet. The choice of business structure has significant tax consequences. For SQE1, you need to understand the tax treatment of different entities, double taxation, and VAT obligations. This is often tested in scenario questions combining company law and tax.

Key Principles for SQE1

  • Corporation Tax - Companies: Companies are taxed on their taxable profits at the corporation tax rate (currently 25% for larger companies, 19% for smaller companies). A company pays corporation tax on trading profits, investment income, and capital gains. Corporation tax is a company-level tax (the company is a taxable entity). This is a key distinction in Types of Business Organisations.

  • Income Tax - Individuals: Sole traders, partners, and LLP members are taxed as individuals on income derived from the business. They are taxed on trading profits at progressive income tax rates. Individuals are the taxable entities, not the business structure.

  • Capital Gains Tax (CGT): Individuals pay CGT on gains from disposing of assets. Companies do not pay CGT—they pay corporation tax on capital gains. This is a key distinction: individuals have a separate CGT regime; companies are taxed on gains under the corporation tax system.

  • Double Taxation - Companies: A company's profits are subject to corporation tax. If the company distributes profits as a dividend to shareholders, shareholders pay income tax on the dividend (at the dividend tax rate, with a dividend allowance). This creates double taxation: once at company level (corporation tax) and once at shareholder level (income tax on dividends). This is a crucial issue in Company Finance and Financial Reporting when advising on distributions.

  • Partnership Taxation - Transparency: A partnership is tax-transparent. The partnership itself is not a taxable entity. Each partner is taxed personally on their share of the partnership's profits (whether distributed or not). This avoids the double taxation problem of companies. Understand the structure in Partnerships and LLP Regulation.

  • LLP Taxation: An LLP is treated like a partnership for tax purposes (despite being a company for legal purposes). An LLP is tax-transparent. Members are taxed personally on their share of profits.

  • Sole Trader Taxation: A sole trader pays income tax on trading profits at progressive rates. There is no separate entity-level tax.

  • VAT - Registration: A business must register for VAT if its turnover exceeds £90,000 in a 12-month period. VAT registration is mandatory above this threshold (unless exempt supplies only). A business can voluntarily register below the threshold.

  • VAT - Rates: The standard rate is 20% (applies to most supplies). Reduced rate is 5% (e.g., domestic fuel). Zero rate is 0% (e.g., books, newspapers, certain food). Exempt supplies (e.g., insurance, financial services) do not attract VAT but input tax cannot be recovered.

  • VAT - Input and Output Tax: A VAT-registered business charges output tax (VAT) on supplies to customers. Input tax is VAT paid on purchases. A business recovers input tax by deducting it from output tax. The net VAT is remitted to HMRC.

  • SDLT - Stamp Duty Land Tax: A buyer pays SDLT on transactions involving land or buildings. SDLT is a transaction tax (not annual). The rate depends on the property value and use (residential or non-residential). This is relevant when a business acquires property.

  • National Insurance Contributions (NICs): Employees pay Class 1 NICs (primary contributions) at 8% of earnings above £12,570 (2025/26). Employers pay Class 1 NICs (secondary contributions) at 15% of earnings above £9,100. Self-employed individuals pay Class 2 and Class 4 NICs.

  • Class 2 NICs: A self-employed person pays a flat-rate Class 2 contribution (£163.80 per year 2025/26) if profits exceed £6,725.

  • Class 4 NICs: A self-employed person pays Class 4 NICs at 9% on profits between £12,570 and £50,270, and 2% above that (2025/26). This is in addition to Class 2.

Exam tip

The partnership tax transparency rule is a perennial SQE1 trap. Partners are taxed personally on profit shares at progressive income tax rates—not at corporation tax rates. When you see a partnership in a scenario, ask yourself: is the partnership itself being taxed, or are the individual partners being taxed?

Quick Comparison: Tax Treatment by Business Structure

| Feature | Company | Partnership | Sole Trader | LLP | |---------|---------|-------------|-------------|-----| | Entity Level Tax | Corporation tax on profits (25%/19%) | No entity-level tax | No entity-level tax | No entity-level tax | | Individual Tax | Shareholders pay income tax on dividends | Partners taxed on profit share | Self-employed on profits | Members taxed on profit share | | Double Taxation | Yes (corporation tax + dividend tax) | No | No | No | | Capital Gains | Corporation tax on gains | CGT on individual gains | CGT on individual gains | CGT on individual gains | | VAT | Same rules (register if turnover >£90k) | Same rules | Same rules | Same rules | | NICs | Employees pay Class 1; employer pays Class 1 | Partners pay Class 2/4 (self-employed) | Sole trader pays Class 2/4 | Members pay Class 2/4 (self-employed) | | Tax Transparency | No (company is taxable entity) | Yes (partners taxed individually) | Yes (sole trader taxed individually) | Yes (members taxed individually) |

Quick Summary

  • Companies pay corporation tax on profits (25%/19%); shareholders pay income tax on dividends (double taxation)
  • Partnerships are tax-transparent; partners taxed on profit share individually at progressive income tax rates (no entity-level tax)
  • VAT registration mandatory at £90,000 turnover threshold; standard rate 20%, reduced 5%, zero 0%, exempt
  • Sole traders and self-employed (partners, LLP members) pay Class 2 (flat) and Class 4 NICs (9%) in addition to income tax
  • Companies pay corporation tax on capital gains; individuals pay CGT—different regimes and rates
  • Double taxation is the key tax inefficiency of companies: same profit taxed twice (corporation tax + dividend tax) = significant cost advantage to partnerships

How This Appears in SQE1 Questions

Scenario: Two business partners expect £200,000 in annual profit. Should they operate as a company, partnership, or LLP? A company would pay 19% corporation tax (£38k), then dividend tax on distributions (another £17.6k). A partnership would pay income tax (40% for each = £80k) + Class 4 NICs (9% = £18k). Which is more tax-efficient and why?

You'll encounter scenarios asking you to:

  • Identify the most tax-efficient structure: Should the business be a company, partnership, or LLP? What are the tax consequences of each choice?

  • Calculate double taxation: A company with £100k profit pays corporation tax. What is the after-tax dividend available to shareholders? What tax do shareholders pay on the dividend? (Connected to shareholder rights detailed in Shareholders and Share Capital.)

  • Address VAT obligations: When must a business register for VAT? What is the VAT treatment of a supply? When can input tax be recovered?

  • Advise on taxation of profits: If partners or LLP members earn £50k each, how is this taxed? (Individually, through self-assessment, with Class 2/4 NICs.)

  • Spot the tax trap: Students assume partnerships pay corporation tax (wrong). Partnerships are tax-transparent; partners are taxed individually. This is the single most common exam mistake.

Common Mistakes Students Make

  • Partnerships pay corporation tax: Wrong. Partnerships are tax-transparent. Partners are taxed personally on their profit shares. This is a classic SQE1 trap.

  • Forgetting double taxation on companies: Companies pay corporation tax on profits. Shareholders then pay income tax on dividends. The same money is taxed twice. This makes companies less tax-efficient than partnerships for distribution of profits.

  • Confusing CGT with corporation tax on gains: Individuals pay CGT on capital gains. Companies pay corporation tax on gains (included in taxable profits). The rates and rules are different.

  • Overlooking VAT threshold and registration: Students forget the £90,000 turnover threshold for mandatory registration. Voluntary registration is available below this threshold but is not automatic.

  • Forgetting NICs for self-employed: Partners and sole traders must pay Class 2 and Class 4 NICs in addition to income tax. This is a significant cost that employees do not face.

  • Missing the distinction between distributions and profits: In a partnership, each partner is taxed on their profit share regardless of whether it is distributed. In a company, shareholders are only taxed when they receive a dividend.

  • Assuming all business structures are taxed the same: Different structures have very different tax consequences. The choice of structure should be informed by tax planning.

Quick check questions based on this article.

Question 1

Scenario

A private company limited by shares has been trading profitably for three years. The company has accumulated reserves and the directors wish to distribute a dividend to the shareholders. The company's most recent annual accounts, which were prepared nine months ago, show distributable profits of £200,000. Since the accounts were prepared, the company has entered into a significant contract that resulted in a loss of £180,000. The directors are aware of this loss but have not prepared interim accounts. The company's articles adopt the model articles without amendment. The directors propose to declare a dividend of £150,000 based on the figures in the most recent annual accounts. One of the shareholders queries whether the dividend can lawfully be paid given the subsequent loss. The company has three directors and four shareholders. The directors have taken informal advice from the company's accountant, who has confirmed that the most recent filed accounts show sufficient distributable profits. The accountant has not been told about the significant loss.

Can the company lawfully pay the proposed dividend of £150,000?

Question 2

Scenario

A sole trader operates a catering business providing food and drink at corporate events. The business has been trading for 18 months. In the first 12 months, the business had a turnover of £60,000. In the most recent quarter, the business secured several large contracts. The business's cumulative taxable turnover for the last 12 months has now reached £92,000. The current VAT registration threshold is £90,000. The sole trader has not registered for VAT. A friend who is an accountant mentions that the sole trader may need to register for VAT. The sole trader is unsure whether registration is required, because she has heard that food supplies are exempt from VAT. The sole trader's main expenses are ingredients, van hire, and staff wages. The sole trader has not charged VAT on any of her invoices to date.

What is the sole trader's obligation in relation to VAT registration?

Question 3

Scenario

A solicitor acts for a company on the sale of its business as a going concern. The company is VAT-registered and operates a chain of sandwich shops. The purchaser is also VAT-registered and intends to continue operating the sandwich shops. The solicitor has been instructed to ensure that the sale qualifies as a Transfer of a Going Concern (TOGC) for VAT purposes, so that no VAT is charged on the sale. The purchase price is £800,000. The solicitor has verified that both parties are VAT-registered and that the purchaser intends to carry on the same kind of business. The purchaser's solicitor has confirmed that the purchaser will use the same trading name and premises. However, the solicitor has discovered that one of the conditions for TOGC treatment may not be satisfied. The purchaser intends to convert two of the five shops into juice bars, ceasing sandwich sales at those locations immediately upon completion. The seller's solicitor must advise on the implications.

Which of the following best describes the solicitor's advice on the TOGC position?
