Understanding Limited Company Tax in the UK: Business Tax Basics
When running a limited company in the UK, understanding how tax works is essential. Taxes can feel complicated, but breaking them down into clear, manageable parts helps. This guide will walk you through the basics of limited company tax, explaining key concepts and offering practical advice. Whether you are just starting out or looking to sharpen your knowledge, this post aims to make tax less daunting and more straightforward.
Business Tax Basics for Limited Companies
Limited companies in the UK are separate legal entities. This means the company itself pays tax on its profits, not the individual owners directly. The main tax a limited company pays is Corporation Tax. As of the current tax year, the Corporation Tax rate is 25% for companies with profits over £250,000, and 19% for those with profits up to £50,000. Companies with profits between these thresholds pay a tapered rate.
Corporation Tax is charged on the company’s taxable profits. These profits include income from sales, minus allowable business expenses. It’s important to keep accurate records of all income and expenses to calculate this correctly.
What Counts as Taxable Profit?
Taxable profit is not just what you see in your accounts. Some expenses are not allowable for tax purposes, such as client entertainment or personal expenses. On the other hand, some costs like salaries, office rent, and business travel are deductible.
For example, if your company earns £100,000 in revenue and has £40,000 in allowable expenses, your taxable profit would be £60,000. You would then pay Corporation Tax on that £60,000.

How to File and Pay Corporation Tax
Corporation Tax must be reported to HM Revenue & Customs (HMRC) through a Company Tax Return (CT600). This return is usually due 12 months after the end of your company’s accounting period. However, the tax itself must be paid within 9 months and 1 day after the accounting period ends.
Filing on time is crucial to avoid penalties. Many companies use accounting software or hire accountants to help with this process. Keeping your records organised throughout the year makes filing much easier.
Payment Methods and Deadlines
You can pay Corporation Tax online via HMRC’s website, by bank transfer, or through other approved methods. Setting reminders for deadlines helps prevent late payments, which can incur interest and fines.
Is it Better to Pay Yourself a Salary or Dividends?
One common question is how to pay yourself from a limited company. The two main options are salary and dividends. Each has different tax implications.
Salary
Paying yourself a salary means the company treats you as an employee. You will need to operate PAYE (Pay As You Earn) and deduct income tax and National Insurance contributions (NICs). The company also pays employer NICs on your salary.
Salaries are a deductible expense for the company, reducing its taxable profits. However, higher salaries mean more NICs for both you and the company.
Dividends
Dividends are payments made to shareholders from company profits after Corporation Tax. They are not subject to NICs, which can make them more tax-efficient. However, dividends do not reduce the company’s taxable profits.
For example, if you pay yourself a small salary up to the personal allowance (currently £12,570) and take the rest as dividends, you can minimise NICs while still drawing income.
Finding the Right Balance
Many directors choose a mix of salary and dividends to optimise tax efficiency. It’s wise to consult with an accountant to tailor this to your specific situation.

Other Taxes Limited Companies Should Know About
Besides Corporation Tax, limited companies may encounter other taxes:
Value Added Tax (VAT): If your turnover exceeds the VAT threshold (£85,000), you must register for VAT and charge it on sales.
PAYE and National Insurance: If you have employees, you must operate PAYE and pay employer NICs.
Business Rates: If you occupy commercial property, you may need to pay business rates.
Capital Gains Tax: If your company sells assets like property or shares, capital gains tax may apply.
Understanding these taxes helps you plan better and avoid surprises.
Practical Tips for Managing Limited Company Tax
Managing tax efficiently requires good habits and planning. Here are some practical tips:
Keep Accurate Records: Use accounting software or spreadsheets to track income and expenses.
Separate Business and Personal Finances: Maintain a dedicated business bank account.
Plan Your Payments: Set aside money regularly to cover Corporation Tax and other liabilities.
Claim All Allowable Expenses: Don’t miss out on deductions that reduce your taxable profit.
Stay Informed: Tax rules can change, so keep up to date or work with a trusted accountant.
Consider Tax Reliefs: Research available reliefs like R&D tax credits or Annual Investment Allowance.
By following these steps, you can reduce stress and keep your company’s finances healthy.
