  • UK Tax Types: 7 Critical Things Small Businesses Need to Know in 2026

As of 2026, the topic of UK Tax Types is critically important, especially for small businesses operating in Enfield and North London. While starting a company in the UK is relatively straightforward, understanding the tax system correctly is a crucial step for maintaining a sustainable business.

In this guide, we explain the most common types of taxes small businesses encounter in a clear and simple way.

1. Corporation Tax

The most fundamental tax for limited companies is Corporation Tax.

What Is Corporation Tax?

Corporation Tax is the tax paid on the profits a company generates. As of 2026, tax rates vary depending on the company’s level of profit:

  • Lower profits are taxed at a reduced rate of 19%.

  • Higher profit bands may be taxed up to 25%.

The tax declaration and payment process is managed by the official authority HM Revenue & Customs (HMRC).

When Is It Paid?

  • Payment must be made 9 months and 1 day after the end of the accounting period.

  • The Company Tax Return must be submitted within 12 months.

Incorrect calculations or late submissions can lead to serious penalties.

2. VAT (Value Added Tax)

VAT is an indirect tax applied to the sale of goods and services in the UK.

When Is VAT Registration Required?

As of 2026:

  • VAT registration is mandatory if annual turnover exceeds £90,000.

  • Below this threshold, registration is optional.

Standard VAT Rate

  • Standard rate: 20%

  • Reduced rates may apply to certain goods and services.

The VAT system requires regular reporting. Incorrect VAT declarations may trigger serious investigations by HMRC.

3. PAYE (Pay As You Earn) and Payroll Taxes

If you employ staff, you must register for the PAYE system.

The PAYE system includes:

  • Income tax deductions from employee salaries

  • National Insurance contributions

  • Pension contributions

All of these processes are managed through integration with HMRC.

Payroll errors can result in:

  • Financial penalties

  • Interest charges

  • Increased risk of audits

For this reason, payroll management often requires professional support.

4. Self Assessment

Self Assessment is the personal income tax reporting system.

Who must complete a Self Assessment?

  • Sole traders

  • Company shareholders

  • Individuals receiving dividend income

  • People with additional income sources

The online filing deadline is typically 31 January. Late submissions automatically result in penalties.

5. National Insurance Contributions (NIC)

National Insurance is a contribution to the UK’s social security system.

There are two main categories:

  • Class 1 (for employees)

  • Class 2 and Class 4 (for sole traders)

These payments are important for pension eligibility and certain state benefits.

6. Dividend Tax

Limited company owners may choose to receive dividends instead of salary.

As of 2026:

  • There is a dividend allowance threshold.

  • Income above this allowance is taxable.

  • Tax rates vary depending on income brackets.

Without proper dividend planning, unnecessary taxes may be paid.

7. Business Rates

If you operate from a physical office or commercial property, you may need to pay Business Rates.

However, small businesses may qualify for Small Business Rate Relief.

In commercial areas such as Enfield, these costs should be carefully planned.
