Running a small business in the UK has its unique challenges and can be quite an overwhelming task. Whether you are a well-established business or a start-up among the many responsibilities the priority is given to financial management and that is incomplete without taxes. Taxation laws can be complex, and failing to comply with them can result in penalties. So the main concern for small businesses especially is always understanding when and how to pay taxes. The answer to the question of when a small business has to pay tax in the UK is complex as tax obligations of a small business depend on various factors, such as its legal structure (sole trader, partnership, or limited company), annual turnover, and the types of taxes applicable. Furthermore, businesses may need to pay income tax, corporation tax, VAT, National Insurance Contributions (NICs), and business rates, among others. In this blog, we will let you know about everything on when does a small business have to pay tax in the UK.

Compliance with Taxes
Read below to have a fair understanding of the different tax obligations small businesses face in the UK, including when they need to start paying taxes and how to remain compliant.
1. Types Of Taxes That Apply to Small Businesses:
Small businesses must be aware of all the different types of taxes they might have to pay. This includes income tax paid by sole traders and partnerships based on business profits or corporation tax paid by limited companies on their profits. VAT is charged on goods and services if a business exceeds the VAT threshold. NICs are paid by businesses and self-employed individuals. Additionally, business rates apply to businesses operating from commercial properties. Being familiar with various taxes is critical for understanding when a small business is required to pay tax in the UK and avoiding non-compliance.
2. Income Tax for Sole Traders and Partnerships:
If you operate as a sole trader or partnership, you must pay income tax on your business profits. Every business owner has a personal tax-free allowance. If your profits exceed this allowance, you will be taxed based on income tax bands. Sole traders and partnerships must file a self-assessment tax return. If your business starts generating taxable profits, you must register for self-assessment with HMRC. This is a key point in determining when a small business has to pay tax in the UK.
3. Corporation Tax for Limited Companies:
If your business is structured as a limited company, it must pay corporation tax on profits which is currently 19-25% depending on profit levels. Businesses need to register with HMRC within three months of starting trading. Unlike sole traders, limited companies do not have a personal allowance which means all profits are taxable. If you operate a limited company, knowing your deadlines for corporation tax is essential to avoid penalties and ensure compliance.
4. When Should a Small Business Register for VAT?
VAT (Value Added Tax) is another critical aspect of taxation for small businesses. Businesses must register for VAT if their annual turnover exceeds £85,000 which is the VAT registration threshold or they expect to exceed the threshold within the next 30 days. Failing to register for VAT when required can result in penalties. Understanding VAT obligations helps determine when a small business has to pay tax in the UK.
5. National Insurance Contributions (NICs) for Businesses:
National Insurance Contributions (NICs) are mandatory for both self-employed individuals and employers. Businesses must calculate and submit NICs on time to HMRC to remain compliant and avoid legal consequences.
6. Business Rates for Commercial Premises:
If a small business operates from a commercial property, it may have to pay business rates. Business rates are calculated based on the rateable value of the property. Business rates are an essential cost for businesses with offices, shops, and warehouses.
7. PAYE and Employer Responsibilities:
If a business employs staff, it must set up PAYE (Pay As You Earn) to deduct income tax and NICs from employee wages. They also have to submit payroll reports to HMRC. Employers must ensure timely payroll tax payments to avoid penalties.
8. Deadlines for Paying Taxes:
Small businesses must meet specific tax deadlines to stay compliant and avoid legal repercussions. This is the most common mistake small businesses make as they cannot keep track of tax deadlines. Missing deadlines do not only result in penalties but also interest charges.
9. Tax Deductions and Allowances for Small Businesses:
Small businesses can claim tax deductions to reduce their tax liabilities. Deductible expenses include office rent and utilities, business travel and mileage, employee wages and benefits, equipment and software, and marketing and advertising costs. Claiming allowable expenses correctly helps reduce taxable profits.
10. Failing to Pay Taxes on Time:
If a business fails to pay taxes on time, it may face late payment penalties and interest charges on overdue taxes. Furthermore, they are susceptible to HMRC investigations and audits along with legal action in case of non-compliance continues. To avoid penalties, businesses should maintain proper financial records and file returns on time.
