🧾 Can your limited company claim expenses before it starts trading?
In many cases, yes.
If you have set up a limited company but have not started trading yet, some costs may still qualify for Corporation Tax relief once the business starts.
Under the pre-trading rules, certain qualifying expenses incurred up to 7 years before trading begins can potentially be treated as if they were incurred on the first day of trading.
Examples may include:
• advertising and marketing
• business insurance
• certain software costs
• professional fees
• some business travel
• certain premises costs
The important question is:
Would the cost have been allowable if the company was already trading?
If the answer is no, the fact that it was incurred before trading started does not make it allowable.
⚠️ It is also important to understand the difference between pre-trading costs and pre-incorporation costs.
Pre-trading costs are incurred after the company has been formed but before it starts trading.
Pre-incorporation costs are incurred before the company legally exists, and these may need to be treated differently.
Equipment, stock and other capital items can also have their own tax treatment.
The key point?
Keep your invoices and receipts from the very beginning.
Even if your company has not started making sales yet, those early costs could still be important when the first accounts and Corporation Tax return are prepared.
