Starting a new business involves upfront costs before you officially incorporate your company. Fortunately, HMRC allows you to reclaim certain pre-trading expenses — potentially saving your business money during its crucial early days. Understanding what qualifies, how to claim, and the relevant deadlines can ensure you don’t miss out on valuable tax relief.
| Aspect | Pre-Trading Expenses | Post-Incorporation Expenses |
|---|---|---|
| When incurred | Before company registration with Companies House | After company registration |
| Tax treatment | Can be claimed as allowable expenses if directly related to setting up the business | Claimed as normal business expenses against profits |
| Claim deadline | Claimed in first company tax return (CT600) | Claimed annually with company accounts |
| Examples | Market research, professional fees, initial stock purchase | Rent, salaries, utilities, ongoing purchases |
What Are Pre-Trading Expenses?
Pre-trading expenses are costs your business incurs in the period before it officially starts trading or before it is incorporated as a limited company. This period usually covers the time when you are planning, researching, and setting up your business but have not yet begun making sales or providing services.
For limited companies, the key date is the date the company is incorporated and registered at Companies House. Any qualifying expenses incurred up to seven years before this date can potentially be claimed, provided they relate directly to the business activities you will carry out.
Which Expenses Qualify?
HMRC allows you to claim back expenses that are wholly and exclusively for the purpose of the business, even if incurred before the company exists. Typical qualifying expenses include:
- Market research and feasibility studies
- Professional fees such as accountants, solicitors, and consultants
- Travel and subsistence costs related to business setup
- Office supplies and stationery purchased before trading
- Initial stock or raw materials bought in preparation for trading
- Website design and domain registration costs
However, expenses such as entertaining clients, personal costs, or anything not directly related to the business are not allowable.
Time Limits for Claiming
Generally, you can claim pre-trading expenses incurred up to seven years before your company starts trading. The expenses must be incurred with the intention of setting up the company’s business activities. This generous time frame offers flexibility for entrepreneurs who spend significant time planning before incorporation.

How to Claim Pre-Trading Expenses
To claim pre-trading expenses, you must include them in your first Company Tax Return (CT600) submitted to HMRC. This return covers the company’s accounting period, which begins on the date of incorporation. You can then deduct these expenses from your taxable profits, reducing your corporation tax bill.
Make sure to keep clear and accurate records of all pre-trading costs, including receipts, invoices, and bank statements. HMRC may request evidence to support your claim, so thorough documentation is essential.
Steps to Claim Pre-Trading Expenses
- Compile all receipts and invoices for costs you incurred before incorporation.
- Confirm these expenses were wholly and exclusively for business purposes.
- Include the total amount of qualifying expenses in your first CT600 tax return under allowable business expenses.
- Submit the CT600 by the statutory deadline, usually 12 months after the end of the accounting period.
- Retain all records for at least six years in case HMRC requests them later.

Common Mistakes to Avoid When Claiming
Claiming pre-trading expenses can be straightforward if you follow the correct process, but errors can lead to rejected claims or penalties. Avoid these common pitfalls:
- Claiming personal or non-business expenses
- Forgetting to keep proper documentation and evidence
- Including expenses incurred after the company started trading
- Missing the CT600 filing deadline
- Not seeking professional advice if unsure about specific expenses
Consulting an accountant or business adviser can help ensure your claim complies with HMRC rules and is maximised appropriately.
Pre-Trading Expenses vs Start-Up Costs
It’s useful to distinguish between pre-trading expenses and general start-up costs. Pre-trading expenses occur before your business is formally trading — that is, before making sales or providing services. Start-up costs can include pre-trading expenses but also encompass costs incurred in the early months of trading.
Start-up costs can be claimed as allowable business expenses in your annual accounts, but pre-trading expenses must specifically relate to the period before trading began. Understanding this difference helps ensure accurate accounting and tax reporting.
Key Takeaways
- You can claim back certain business expenses incurred up to seven years before your company starts trading or is incorporated.
- Qualifying expenses must be wholly and exclusively for business purposes, such as market research, professional fees, and initial stock.
- Claims are made through your first Company Tax Return (CT600) and must be supported by accurate records and evidence.
- Avoid claiming personal expenses or costs incurred after trading begins to prevent HMRC disputes.
- Seek guidance from HMRC, use GOV.UK resources, or consult an accountant to maximise your claim correctly.
Can sole traders claim pre-trading expenses?
Sole traders cannot claim pre-trading expenses in the same way as limited companies, but they can deduct certain start-up costs from their taxable profits once trading begins. For more details, see sole trader vs limited company.
How long do I have to keep records of pre-trading expenses?
HMRC requires you to keep business records, including pre-trading expenses, for at least six years from the end of the accounting period they relate to. This ensures you can provide evidence if HMRC requests a review.
What if I forget to claim pre-trading expenses in my first CT600?
If you miss claiming pre-trading expenses in your first tax return, you may be able to amend your CT600 within 12 months of the filing deadline. Beyond that, it is more difficult to claim, so it’s important to include these expenses promptly.
