How Pre-Trading Expense Relief Works
Starting a business often involves significant costs before income begins to flow. HMRC recognises this with a specific relief for pre-trading expenditure. Under s.57 ITTOIA 2005 (for sole traders and partnerships) and s.61 CTA 2009 (for limited companies), qualifying expenses incurred up to 7 years before the first day of trading are treated as if they were incurred on the first day of trading.
This is particularly valuable because it means these costs reduce your taxable profit in the first year, potentially creating a first-year loss that can be carried back to earlier years when you may have paid tax as an employee. The relief effectively links your pre-business spending to your trading income, ensuring you get a tax deduction for genuine business costs.
What Qualifies and What Does Not
Qualifying expenses include professional fees (accountants, solicitors, consultants), market research and feasibility studies, website development costs (revenue element), training directly related to the trade, subscriptions to trade publications, travel costs for business purposes, and general business running costs incurred before launch.
The fundamental test is whether the expense would have been tax-deductible as a trading expense if it had been incurred after trading started. If yes, it qualifies as pre-trading expenditure. If no, it does not.
Non-qualifying items include capital expenditure (purchase of equipment, machinery, vehicles, fixtures — claim capital allowances for these), private or personal costs, and expenses incurred more than 7 years before the first trading date.
Interaction with Trading Loss Relief
If your first-year trading expenses (including the brought-forward pre-trading expenses) exceed your first-year income, you will have a trading loss. As a new business in the first 4 years of trading, you can carry this loss back 3 years under opening year loss relief (s.72 ITA 2007), potentially generating a refund of tax paid in years when you were employed. This makes pre-trading expenses doubly valuable for career changers and professionals going self-employed.
Frequently Asked Questions
Pre-trading expenses are costs incurred before a business officially starts trading. Under s.57 ITTOIA 2005 (individuals) and s.61 CTA 2009 (companies), qualifying expenses paid up to 7 years before the first day of trading are treated as if incurred on that first day.
Expenses must be incurred within 7 years of the first day of trading to qualify. Expenses incurred more than 7 years before trading begins do not qualify and cannot be deducted.
Professional fees, market research, website development, travel for business purposes, subscriptions, and other revenue expenses that would have been deductible during trading. Capital expenditure (equipment, machinery) does not qualify — use capital allowances instead.
No. Capital expenditure cannot be claimed as pre-trading expenses. Equipment qualifies for capital allowances (Annual Investment Allowance or Writing Down Allowances) from the first year of trading instead.
Qualifying pre-trading expenses are added to first-year trading expenses. They reduce first-year taxable profit or increase a first-year trading loss. If a loss is created, you can apply trading loss relief to maximise the tax benefit.
Yes. Under s.61 CTA 2009, companies can claim pre-trading expenses incurred up to 7 years before the company's first accounting period begins trading. The rate of relief is the corporation tax rate applicable in the first trading period.
If pre-trading expenses create or increase a first-year trading loss, you can use trading loss relief options: sideways relief against other income, carry back (up to 3 years for new businesses in first 4 years of trade), or carry forward.
Training costs can qualify if directly related to the trade you are about to start and would have been allowable if incurred after trading commenced. Initial training to become qualified in a new area is generally capital in nature and not deductible.
For sole traders, include qualifying pre-trading expenses in the Self-Employment pages of your Self Assessment return for the first year of trading. Keep all receipts. For limited companies, include in the first corporation tax return.
No. The pre-trading expense rules only apply once trading begins. If you never commence the trade, there is no first day of trading against which expenses can be treated as arising, so no deduction is available.
Keep all receipts, invoices, bank statements and contracts. For each expense, document the date, amount, business purpose and connection to the intended trade. HMRC may enquire into startup claims, particularly for large pre-trading expenditure.
Yes. Advertising, marketing, and promotional costs incurred before trading starts can qualify, provided they would have been deductible during trading and are within the 7-year window.
