Managing taxes is a crucial aspect of running a limited company. This comprehensive guide provides essential tax tips for limited companies to help you stay compliant, optimise your tax position, and avoid common pitfalls.

Understanding Annual Accounts and Filing Requirements

After your company’s financial year ends, you must prepare and file full statutory annual accounts and a Company Tax Return. These documents are vital for calculating your Corporation Tax. Critical deadlines to keep in mind:

  • First accounts: 21 months after registering your company with Companies House.
  • Annual accounts: 9 months after the end of your financial year.

Failure to meet these deadlines can result in penalties, so timely preparation is essential.

Paying and Filing Corporation Tax

Corporation Tax is a significant obligation for limited companies. Here are the deadlines:

  • Pay Corporation Tax: Within nine months and one day after the end of your accounting period.
  • File Company Tax Return: Within 12 months after the end of your accounting period.

Your accounting period for Corporation Tax usually matches your financial year, serving as the basis for your tax calculations.

Claiming Allowable Expenses

One of the best ways to reduce your taxable profit is by claiming allowable business expenses. These can include:

  • Office Supplies
  • Travel expenses
  • Professional services

Keeping detailed records and receipts is crucial for substantiating your claims during tax assessments.

Leveraging Tax Reliefs

Several tax reliefs are available to limited companies, which can significantly reduce your tax burden:

  • Research and Development (R&D) Relief: If your company undertakes innovative projects, you may qualify for R&D tax relief.
  • Annual Investment Allowance (AIA): This allowance allows you to claim up to £1 million on qualifying plant and machinery, boosting your capital investments.

Keeping Accurate Records

Maintaining meticulous financial records is good practice and a legal requirement. This includes keeping invoices, receipts, and bank statements. Accurate records simplify audits and support your expense claims.

Consulting a Professional

Given the complexity and constant changes in tax laws, hiring an accountant or tax advisor can be immensely beneficial. A professional can help you navigate the intricacies of tax compliance, optimise your tax position, and ensure you take full advantage of available reliefs and allowances.


Staying on top of your tax obligations as a limited company is essential for compliance and financial health.
