Company pre-trading expenses: check the payer and the purpose

In short: A company can deduct revenue costs it incurred for a trade in the 7 years before it started that trade, if they would have been deductible once trading; they are treated as incurred on the day trading starts (Corporation Tax Act 2009, section 61). Capital items such as equipment fall outside the rule, and the company that incurred the cost must be the one starting the trade, so a founder's personal or sole-trader receipts don't qualify automatically. HMRC's manual sets out the scope of pre-trading relief and who receives relief.

The seven-year window is only one condition, so do not treat every receipt from before launch as an automatic company deduction.

This guide is a preparation checklist for trading companies. It is not a method for transferring a sole trader's historic costs into a new limited company.

Is incorporating a company the same as starting to trade?

No: a company can exist before its trade begins, and a founder can spend money before the company exists, so keep those situations out of one "start-up expenses" total. Write down the incorporation date, the proposed trading-start date and the evidence supporting that start date, then identify who incurred each cost.

Identify the legal customer too: the first bank payment or first invoice alone may not explain the whole position.

If an invoice predates incorporation, belongs to the founder personally, or relates to an earlier sole-trader business, put it in a review column. A later company reimbursement should not be treated as proof that the company qualifies for pre-trading relief. HMRC's same-person condition is the reason to resolve this before entering the claim. HMRC: pre-trading relief.

Which pre-trading costs can qualify for relief?

Revenue costs incurred within seven years before the trade starts can qualify if they would have been deductible after commencement; capital expenditure is outside the pre-trading rule. Stock and amounts deductible after trading begins should not also receive a pre-trading deduction. Capital allowances have separate provisions. HMRC: pre-trading expenditure scope.

Use a schedule with four destinations:

These are working-paper categories, not conclusions about every advertising, training or website invoice. A supplier's description does not determine whether a cost is capital or revenue.

How do you work out the pre-trading relief figure?

Add up only the items provisionally sorted as revenue costs: in the example below, that is £700 of a £3,000 cash total, subject to confirming the conditions. Equipment bought to keep goes to the asset review and stock to the stock record, so neither belongs in the pre-trading figure.

Suppose an already incorporated company incurs the following costs before it starts trading. Assume no VAT recovery and that the facts are as described:

The potential revenue-relief subtotal is £400 + £300 = £700, subject to confirmation of the conditions. It is not the £3,000 cash total. This example does not promise any particular capital allowance or total tax saving.

Qualifying pre-trading revenue expenditure is treated as incurred when the trade begins. Keep the original transaction evidence rather than replacing its actual date with a fictional invoice date. The tax treatment and the document date serve different purposes. HMRC: timing of relief.

How do you prepare a pre-trading expenses claim, step by step?

Fix the dates, identify who incurred each cost, sort every cost, test the revenue items against the conditions, total them, keep the evidence, then check nothing is claimed twice. Only revenue costs incurred within seven years before the trade starts, by the company that starts the trade, belong in the final total.

Step 1: Write down the key dates

Record the incorporation date, the proposed trading-start date and the evidence supporting that start date. A company can exist before its trade begins, and a founder can spend money before the company exists, so keep those situations out of one "start-up expenses" total. The first bank payment or first invoice alone may not explain the whole position.

Step 2: Identify who incurred each cost

For every cost, identify the legal customer and the person who incurred it. If an invoice predates incorporation, belongs to the founder personally, or relates to an earlier sole-trader business, put it in a review column. A later company reimbursement is not proof that the company qualifies: HMRC's same-person condition means the person who incurred the cost must be the person starting the trade.

Step 3: Sort each cost into one of four destinations

Use the four-destination schedule above: potential pre-trading revenue cost, asset or other capital item, stock or payment relating to later trading, and unresolved or personal item. These are working-paper categories, not conclusions about every advertising, training or website invoice. A supplier's description does not determine whether a cost is capital or revenue.

Step 4: Test each revenue cost against the conditions

Revenue costs incurred within seven years before the trade starts can qualify if they would have been deductible after commencement. Capital expenditure is outside the pre-trading rule, and capital allowances have separate provisions. Stock and amounts deductible after trading begins should not also receive a pre-trading deduction. The seven-year window is only one condition, not permission to choose an arbitrary claim year.

Step 5: Total the provisional revenue costs

Add up only the items provisionally sorted as revenue costs — in the example above, £700 of a £3,000 cash total, subject to confirming the conditions. Qualifying pre-trading revenue expenditure is treated as incurred when the trade begins, but keep the original transaction evidence rather than replacing its actual date with a fictional invoice date.

Step 6: Keep the evidence for every item

Keep the invoice, contract, payment evidence, business-purpose explanation and the preparer's conclusion for every item, including the ones you decided not to claim. The tax treatment and the document date serve different purposes, so file the evidence under the original transaction date and note the commencement-period treatment separately.

Step 7: Check nothing is claimed twice

Mark where each item already appears in the accounts so it cannot be deducted twice — for example, stock bought for resale belongs in the stock record, not in a second pre-trading deduction. Keep unresolved items visible until someone has made a documented decision. The claim is ready when every item sits in one destination, has its evidence attached and appears in the calculation only once.

What evidence do you need before claiming?

Keep five pieces of evidence for every item, including the ones you decided not to claim, and mark where each item already appears in the accounts so it cannot be deducted twice. Keep unresolved items visible until someone has made a documented decision. For each cost, keep:

• The supplier's invoice for the cost.
• The contract or order, where there is one.
• Payment evidence showing who actually paid the cost.
• A short explanation of the business purpose.
• The preparer's conclusion on how it is treated.

Once the claim is settled, take the 30-second check to see whether Taxley fits your company.

For a software question after that review, ask Taxley how to enter the agreed figures for your accounting period. Taxley support cannot determine who legally incurred an old expense or approve the relief claim.

Frequently asked questions

Does seven years mean I can choose any later year to claim?

No. The seven-year look-back condition is not permission to choose an arbitrary claim year: qualifying pre-trading revenue expenditure is treated as incurred when the trade begins. Check the commencement-period treatment and any correction needed (HMRC: timing of relief).

Can a new company claim the founder's sole-trader costs?

Not simply by reimbursing them. HMRC's same-person condition means the person who incurred the cost must be the person starting the trade, so costs of the founder personally or an earlier sole-trader business go in a review column. This guide is not a method for transferring those costs (HMRC: who receives relief).

Is equipment bought before trading a pre-trading expense?

Not under the pre-trading rule. Capital expenditure is outside that rule, so equipment bought to keep and use goes to an asset and capital-allowance review instead. In the worked example, £1,500 of equipment is excluded from the £700 revenue subtotal (HMRC: pre-trading expenditure scope).

Can stock bought before trading also get pre-trading relief?

No. Stock and amounts deductible after trading begins should not also receive a pre-trading deduction. Stock bought for resale belongs in the stock record, where it enters the normal accounts and tax calculation; in the worked example, £800 of stock stays out of the pre-trading figure.
