You registered the company on 10 June. But you bought the laptop on 20 May. You paid for the domain name on 1 May. You took a train to meet a potential supplier on 15 April, and you bought the URL on 28 March. None of these costs were incurred by the company because the company did not exist yet.
That does not mean the money is lost. The tax rules allow a new company to claim relief on certain costs incurred before incorporation, but the treatment depends on what was spent, who paid, and whether VAT was charged. Get it wrong and you overpay corporation tax, miss a VAT reclaim, or trigger an unnecessary tax charge on the director.
This is where a good accountant for startup businesses earns their fee. Not by filing the return, but by structuring the claim correctly from day one.
What Counts as a Pre-Incorporation Expense?
Pre-incorporation expenses are costs incurred by the founder (or partners in a pre-existing partnership) before the company was legally incorporated at Companies House. The company cannot incur a cost before it exists. But it can adopt those costs after incorporation and claim tax relief on them, provided the expenses would have been deductible if the company had incurred them directly.
The rule comes from Section 61 CTA 2009. It allows a company to treat certain pre-incorporation expenses as if they were incurred by the company on the date they were actually paid. The expenses must be:
- Incurred within seven years before incorporation
- Wholly and exclusively for the purposes of the trade that the company later carries on
- Not otherwise relieved (e.g. already claimed by a sole trader or partnership)
If those conditions are met, the company can deduct the expense in its first corporation tax return (the CT600) as if it had paid it on the day of incorporation.
Common Pre-Incorporation Costs That Qualify
- Domain names and web hosting
- Legal and professional fees for company formation
- Market research and feasibility studies
- Travel costs for meetings with suppliers, customers, or funders
- Equipment and tools (laptops, software, machinery)
- Stock and raw materials
- Advertising and marketing before launch
- Bank charges for opening a business account
Costs That Do Not Qualify
- Personal living costs (rent, food, utilities at home)
- Costs that are capital in nature but not eligible for capital allowances (e.g. land)
- Expenses already claimed by the individual in a prior self assessment return
- Costs incurred more than seven years before incorporation
The VAT Trap: Pre-Incorporation Input Tax
This is where many startups lose money. If you bought goods or services before the company existed, the supplier will have charged VAT on the invoice. But the invoice is in your name, not the company's. HMRC's policy on pre-incorporation input VAT is restrictive.
The general rule is that a company can only reclaim VAT on supplies made to it. If the invoice is addressed to you as an individual, the company cannot reclaim the VAT, even if the goods are used by the company after incorporation.
There is a narrow exception. If the goods were acquired by the individual as agent for the company and the company existed in substance (even if not yet legally formed), HMRC may allow the claim. But this requires evidence that you intended to act as agent and that the company ratified the purchase after incorporation.
In practice, most startups miss this. The safer route is to delay significant purchases until after the company is registered, or to ensure the supplier issues a credit note to you and re-invoices the company after incorporation. That adds admin, but it preserves the VAT reclaim.
As ICAEW qualified accountants, we see this most often with equipment purchases. A founder buys a £2,000 laptop plus £400 VAT before the company exists. The company cannot reclaim the £400. That is a permanent cost, not a timing difference.
How to Transfer Pre-Incorporation Assets to the Company
If you bought a laptop, a server, or a vehicle before incorporation, the asset is legally yours, not the company's. The company needs to acquire it from you. There are two common routes.
Route One: Sell the Asset to the Company
You transfer the asset to the company at market value. The company pays you, either in cash or by crediting your director's loan account. The company then claims capital allowances on the asset (typically Annual Investment Allowance at 100% up to £1m).
If you sell at market value and that value is higher than what you paid, you may have a capital gain personally. For most startup equipment (laptops, phones, furniture), market value is lower than cost, so no gain arises.
Route Two: Claim the Expense Directly Under S61 CTA 2009
For revenue expenses (domain names, travel, marketing), the company simply claims the deduction in its first tax return. No asset transfer is needed. The cost is treated as if the company paid it on the day of incorporation.
For capital items, you have a choice. You can either claim capital allowances on the deemed cost under S61, or you can transfer the asset and claim allowances on the transfer value. The S61 route is simpler but the allowances are based on the original cost, not market value.
The Director's Loan Account Angle
If you paid for pre-incorporation expenses out of your own pocket, the company owes you that money. It is a director's loan from you to the company. You should record it properly from day one.
Here is how it works in practice. You spent £3,400 on pre-incorporation costs (domain, legal fees, laptop, travel). After incorporation, the company records a credit to your director's loan account of £3,400. That is money the company owes you. When the company later makes profits and pays you, it can repay that loan tax-free. Dividends and salary are separate.
If you do not record the loan, the company gets the tax deduction for the expenses (good), but you lose the repayment mechanism (bad). You have effectively gifted the money to the company.
Most accounting software handles this automatically if you enter the opening balance correctly. Xero, FreeAgent, and QuickBooks all allow you to set up an opening director's loan balance on incorporation.
What Happens If You Were Already a Sole Trader or Partnership?
If you were trading as a sole trader or in a partnership before incorporating, the pre-incorporation expense rules interact with the transfer of a going concern. The key point is that you cannot double-claim.
If you already deducted an expense in your sole trader self assessment (SA103) or partnership return (SA800), you cannot also claim it in the company's first CT600. That would be double relief and HMRC will reject it.
The correct approach is to agree a transfer date with your accountant. The sole trader trade ceases on that date. The company trade begins. Expenses incurred before the transfer date are claimed by the sole trader. Expenses incurred after are claimed by the company. Pre-incorporation expenses incurred before the sole trader trade started (e.g. market research before you began self-employed) can be claimed by the company under S61.
This gets complicated quickly. A sole trader who incorporates part-way through a tax year needs to file both a final self assessment return and a first corporation tax return, with no gaps and no overlaps. That is why we recommend speaking to an accountant for startup incorporations before you file anything.
Practical Steps: What to Do Now
If you have already incorporated and spent money before that date, here is what to do:
- Gather every receipt and invoice from before the incorporation date. Bank statements alone are not enough. You need the supplier's invoice showing the date, description, and VAT.
- Separate revenue from capital. Revenue costs (domain, travel, marketing) go through the profit and loss. Capital costs (laptops, equipment, furniture) go through the balance sheet and attract capital allowances.
- Check the VAT. If the invoice is in your name and dated before incorporation, the company cannot reclaim the VAT. Accept that loss or ask the supplier to reissue.
- Record the director's loan. Enter the total pre-incorporation spend as a credit to your director's loan account in the company's first set of accounts.
- Claim the deduction in the first CT600. Your accountant will include the pre-incorporation expenses in the first corporation tax computation, with a note referencing S61 CTA 2009.
When to Involve an Accountant
Pre-incorporation expenses are straightforward for a single laptop and a domain name. They become complex when you have significant capital purchases, a prior sole trade, or VAT-registered suppliers. The VAT trap alone can cost hundreds or thousands of pounds if handled incorrectly.
If your pre-incorporation spending is over £5,000, or if you were already trading as a sole trader or partnership, get professional advice before filing the first CT600. A correction after filing is possible but costs time and money.
Our ICAEW qualified team handles these incorporations regularly. We work with startups across the UK, from a two-founder tech company in Shoreditch to a husband-and-wife café in Birmingham's Jewellery Quarter. The principles are the same. The paperwork differs.
If you are unsure whether your pre-incorporation costs qualify, contact us. We will review your receipts and tell you what is claimable before you file anything.
Pre-Incorporation Expenses and R&D Tax Credits
If your startup is developing new products or processes, some pre-incorporation costs may qualify for R&D tax credits. The rules are the same: the expense must have been incurred within seven years before incorporation and must relate to R&D activities that the company later carries on.
However, the R&D claim is more complex. You need to demonstrate that the R&D project was ongoing before incorporation and that the costs are directly attributable to qualifying R&D activities. This is an area where specialist R&D advice is essential.
For accounting periods starting on or after 1 April 2024, the merged R&D scheme applies. Loss-making companies with R&D spend over 30% of total costs can use the enhanced R&D Intensive Scheme (ERIS). Pre-incorporation costs can count towards that 30% threshold, but only if they qualify under S61.
Summary
Pre-incorporation expenses are not a tax write-off. They are a legitimate deduction, but only if you follow the rules. The key points:
- Revenue costs qualify under S61 CTA 2009
- Capital costs qualify for capital allowances
- VAT on pre-incorporation invoices is usually lost unless you plan ahead
- Record the spend as a director's loan to preserve the repayment mechanism
- Do not double-claim if you were already a sole trader or partnership
- Get professional advice if the amounts are significant or the structure is complex
A good accountant for startup businesses will catch these issues before the first return is filed. That saves tax, preserves VAT recovery, and keeps the director's loan account clean from day one.
