Tax Considerations for Contractors Outside IR35 with Profits Over £50,000

As a contractor operating outside IR35 with profits exceeding £50,000, there are several financial and tax considerations to keep in mind to optimize your earnings. The interplay of salary, dividends, corporation tax rates, and allowable expenses can significantly impact your net income. Here’s a comprehensive guide to help you navigate these elements efficiently.

1. Tax-Efficient Salary and Dividends

One of the primary strategies to minimize your tax burden as a contractor is to draw a combination of salary and dividends from your limited company. Here’s how this works:

  • Salary: Paying yourself a salary up to the personal allowance threshold (£12,570 for the tax year 2024/25) can be tax-efficient. This salary is deductible as a business expense, reducing your company's corporation tax liability. Additionally, paying yourself a salary above the Lower Earnings Limit (£6,540 for 2024/25) ensures you qualify for state benefits without incurring National Insurance contributions.

  • Dividends: After paying yourself a reasonable salary, you can distribute the remaining profits as dividends. Dividends are taxed at lower rates compared to salaries. For the tax year 2024/25, the dividend tax rates are:

  • 8.75% on dividends within the basic rate band

  • 33.75% on dividends within the higher rate band

  • 39.35% on dividends within the additional rate band

By balancing your salary and dividends, you can minimize your overall tax liability while maintaining a steady income.

2. Corporation Tax Rates for Profits Over £50,000

Corporation tax is another critical consideration. From April 2023, the UK corporation tax landscape changed with the introduction of a new tiered system:

  • Small Profits Rate: 19% on profits up to £50,000.

  • Main Rate: 25% on profits over £250,000.

  • Marginal Relief: Profits between £50,001 and £250,000 are subject to a tapered rate that gradually increases from 19% to 25%.

For instance, if your profit is £100,000, the corporation tax calculation would be:

  • 19% on the first £50,000 = £9,500

  • Marginal relief applies to the remaining £50,000. The effective rate on this portion will be higher than 19% but lower than 25%.

Understanding these rates helps in planning your profit distributions and managing your tax obligations effectively.




3. Allowable Expenses to Stay Under the Threshold

To stay under the corporation tax threshold and optimize your tax position, it's essential to maximize your allowable expenses. Here are some key expenses to consider:

  • Pension Contributions: Contributions to a personal pension plan are deductible as business expenses and can significantly reduce your taxable profit. These contributions also provide long-term financial benefits.

  • Office Expenses: Costs associated with running your business from home, such as a portion of your utility bills, internet, and rent, can be claimed as expenses.

  • Equipment and Software: Purchases of necessary equipment, software, and tools used for your business operations are deductible.

  • Travel and Subsistence: Travel costs incurred for business purposes, including mileage, public transport, and subsistence expenses like meals and accommodation, can be claimed.

  • Professional Fees and Subscriptions: Fees for professional services such as accounting, legal advice, and industry-related subscriptions are allowable expenses.

  • Training and Development: Costs related to professional development and training courses relevant to your business are deductible.

By strategically managing these expenses, you can reduce your taxable profit, potentially keeping it below the higher corporation tax thresholds.


Managing your finances as a contractor outside IR35 with profits over £50,000 requires careful planning and strategic decisions. Balancing a tax-efficient salary with dividends, understanding the implications of the new corporation tax rates, and maximizing allowable expenses are crucial steps to optimize your net income. By taking a proactive approach to financial planning, you can navigate the complexities of the tax system and ensure long-term financial stability.
