Pre-trading expenses are costs incurred before your business starts trading, such as marketing, training, stock, premises, and professional advice needed to prepare for launch.
What are pre-trading expenses?
When starting a new business, a large amount of expenses will likely be incurred before your business starts trading. These expenses are usually necessary to get your business in a position to start trading and will often relate to things such as marketing and website costs, training and development costs, acquiring premises, buying stock and seeking professional advice. For tax purposes, these costs are known as “pre-trading expenses”.
The good news is that it is possible to obtain tax relief for these pre-trading expenses once your business starts trading. To obtain tax relief, the pre-trading expenses must be incurred “wholly and exclusively” for the trade and therefore would have been allowable for tax purposes if the business had been trading at the time the pre-trading expense was incurred.
Pre-trading expenses are valid for 7 years and, for tax purposes, are treated as having been incurred on the first day of trading and deducted from the business’s profit for its first accounting period.
What Can Be Claimed as Pre-Trading Expenses?
Claiming pre-trading expenses can help reduce taxable profit once the business starts trading. These costs must be linked directly to setting up and preparing the business for trade.
Common examples may include:
- Website design and setup costs
- Marketing and advertising before launch
- Training related to the business activity
- Professional fees, such as an accountant or legal advice
- Stock purchased before trading begins
- Office supplies and small equipment
- Business software and subscriptions
- Premises-related setup costs
Each cost should be recorded clearly and supported by receipts, invoices, or bank records. To qualify, the expense must be for the business and would normally have been allowable if the business had already started trading.
What May Not Qualify as Pre-Trading Expenditure?
While many business setup costs may qualify for tax relief, some expenses may not be treated as allowable pre-trading expenditure by HMRC. Expenses must be directly related to preparing the business for trade and incurred wholly and exclusively for business purposes. Personal purchases, entertainment costs, unrelated training, and expenses without proper records may not qualify. Some larger purchases may also be treated separately for tax purposes if they are considered capital assets instead of day-to-day business expenses. Keeping accurate records and seeking professional advice can help reduce mistakes when claiming pre-trading expenses.
Steps to claim pre-trading expenses:
- Keep Detailed Records: Maintain thorough records of all expenses, including invoices, receipts, and payment details. This documentation is crucial when claiming pre-trading expenses.
- Classify Expenses Correctly: Classify each expense accurately according to HMRC guidelines to ensure precise reporting. Different categories, such as marketing, legal, or office setup, may have specific criteria.
- Adhere to Time Limits: Be mindful of HMRC’s time limits for submitting claims. Timely submission is crucial, and awareness of deadlines is vital to comply with HMRC regulations.
- Consult with Tax Professionals: Seeking advice from tax professionals or accountants can help you navigate the complexities of claiming pre-trading expenses. They can provide expert insights into HMRC regulations, ensuring compliance with UK tax laws.
- Explore Government Incentives: Research and leverage any available government incentives or tax reliefs designed to support businesses in their early stages. HMRC may offer schemes that can ease the financial burden of pre-trading expenses.
Example of Pre-Trading Expenses
Priti has a full-time job as an administrative assistant, but she decides to retrain and become a nutritionist. Priti incurred training costs of £3,000 in December 2019. The COVID-19 pandemic in early 2020 meant that Priti remained in her employed role as she was not able to undertake the final stages of her nutritionist qualification. After the pandemic, Priti incurred further certification costs of £1,000 in December 2021. Priti qualified as a nutritionist in June 2022. Priti left her job in September 2022 and became a full-time self-employed nutritionist.
HMRC would likely consider that Priti started trading in September 2022, as that is when she started providing nutritionist services. Any pre-trading expenses incurred in the 7 years before September 2022, including the £3,000 training costs from December 2019 and the £1,000 certification costs from December 2021, can be treated as allowable business expenses from 1 September 2022. These pre-trading expenses would be deducted from Priti’s business profit in her first year of trading.
