If you’re an IT contractor working through a limited company, make sure your tax planning is sharp, compliant, and built around your real-world working life.
Whether you’re a developer, project manager, cybersecurity expert, or tech consultant, this blog outlines how to save tax, stay compliant, and get real value from your accountant.
Why Generalist Accountants Don’t Cut It Anymore
Too many IT contractors lose out on tax savings because they’re working with a generalist accountant who doesn’t understand their sector. If your accountant is advising farmers one minute and retailers the next, they might not be:
- Claiming all allowable IT-related expenses
- Structuring your salary/dividend split for maximum tax efficiency
- Applying IR35 rules correctly
In a sector as fast-moving and niche as IT, a specialist accountant gives you an advantage.
Five Key Tax Tips for IT Contractors
1. Plan Your Salary & Dividends Wisely
A balanced combination of salary and dividends remains one of the best tax strategies.
- Salary set at or near your personal allowance
- Dividends taxed at basic rate of tax
- Spouse shareholding can help reduce the household tax bill
2. Take Advantage of Spouse Salaries
If your spouse helps out with admin, bookkeeping, or sales:
- Pay them a fair salary—it’s tax-deductible for the company
- It can shift income into lower tax bands
This is often overlooked but can add up to real savings over time.
3. Claim Every Allowable Expense
Common expenses you should be claiming:
- Laptops, phones, and software subscriptions
- Use of home as office
- Travel to client sites
- Training and certifications
- Cybersecurity tools
A specialised contractor accountant knows the full range of IT-specific expenses you’re entitled to.
4. Contribute to a Pension via the Company
Company pension contributions are one of the most tax-efficient ways to withdraw profits:
- Fully deductible for Corporation Tax
- Not subject to National Insurance or dividend tax
- Helps you save for the future while reducing current tax
5. Get Your IR35 Position Reviewed
If you contract through agencies or work for large end clients, you may be affected by IR35. Getting it wrong can be expensive.
- Have your contract reviewed by a specialist
- Document your working practices
- Use IR35 insurance if needed
Bonus: Plan Ahead With Early Year-End Accounts
Filing your accounts promptly after your year-end means:
- You can adjust dividends, pension contributions, or salary
- You’ll have more notice for Corporation Tax bills
- You can make informed decisions for the next tax year
Waiting 9 months until the deadline often means missed opportunities. By this point you are reacting and are often backed into a corner. Get the accounts done swiftly after year end.
