Startup Costs Before Incorporating: What a C Corp Can Deduct

A C corporation can claim founders' pre-incorporation costs only once it bears them: by repaying them, owing them as a loan, or recording a contribution. Formation fees are organizational costs and pre-launch market research is a start-up cost: each gets a limited deduction in the year business begins, the rest over 180 months. Qualifying US development is research, deducted when paid.

Can a corporation deduct expenses paid before incorporation?

Yes, but only costs the corporation itself bears, and most of them are not deducted at once. A cost a founder paid before incorporating becomes the corporation's when the corporation repays it, owes it as a loan, or records it as the founder's contribution. Nothing on that list is automatic: without a record, the cost usually helps no one's return.

Once the corporation bears a cost, what it bought sets the tax treatment:

What was paid forCategoryTreatment
Charter, bylaws, organizational minutes, state incorporation fees, necessary accountingOrganizational cost (section 248)Up to $5,000 in the year business begins, rest over 180 months
Market research, travel and consultants to investigate or set up the businessStart-up cost (section 195)Up to $5,000 in the year business begins, rest over 180 months
Qualifying product development done in the US, including softwareResearch cost (section 174A)Deductible in the year paid, if the conditions below are met
Legal work to issue stock or raise moneyCapitalizedNot deductible now; loan costs are spread over the loan's term
Code, laptops or other property the founder owns and contributesAssetHeld at the founder's basis; depreciated or amortized, not expensed

A case is not simple when the corporation has not yet begun business, when developers or contractors were paid before the company existed, when a founder contributes code or equipment for shares, or when the first return has already been filed. Gather receipts, proof of who paid and when, contracts, invoices that split legal work, IP assignments and the record of how each founder was repaid.

Organizational costs vs startup costs: which is each?

An organizational cost creates the corporation itself; a start-up cost investigates or sets up the business it will run. The two are separate pools, so each gets its own first-year amount.

  • Organizational costs must be incident to creating the corporation and chargeable to capital account. The regulation lists legal work on the charter, bylaws, organizational minutes and terms of the original stock certificates, necessary accounting, temporary directors' and organizational meetings, and fees paid to the state of incorporation.
  • Start-up costs are amounts paid to investigate or create an active business, or for profit-seeking activity before the business begins, that would be deductible if the same business were already running (section 195(c)(1)).
  • Neither covers costs to issue or sell shares, or costs to transfer assets to the corporation (26 CFR 1.248-1(b)(3)). Equipment is depreciable property, not a start-up cost.
  • Research is carved out: section 195(c)(1) excludes any amount deductible under section 174A, so qualifying research is never a start-up cost.

How much is deducted in the first year, and what is spread over 15 years?

In the year the corporation begins business, each pool allows up to $5,000, reduced dollar for dollar by the pool's total above $50,000. The rest is deducted evenly over 180 months, starting with the month business begins, so the first year also gets those months' share (26 CFR 1.195-1; 26 CFR 1.248-1).

Total in one poolFirst-year amountThe rest
Up to $5,000All of itNothing left
Above $5,000, up to $50,000$5,000Monthly over 180 months
Above $50,000$5,000 minus the excess, not below zeroMonthly over 180 months

The organizational pool uses the same figures: $5,000 and $50,000 (section 248(a)). Nothing in either pool is deducted before the business begins.

When does a pre-revenue startup begin business for these rules?

A corporation begins business when it starts the operations it was organized for, which is not the day it is incorporated. The organizational-cost regulation calls this a question of fact: getting the charter is not enough, but activities advanced far enough to establish the nature of the business are, and buying the operating assets the business needs may be.

The regulation does not make revenue the test. For start-up costs, section 195(c)(2) leaves the start date to regulations, and 26 CFR 1.195-1 does not define it, so the date is also a judgment on the facts. A startup still building its product may not have begun business, so its start-up and organizational costs wait for a later return. Picking the wrong year is costly to undo: once amortization has run on two or more returns, changing the start year is a change in accounting method.

Are developer and contractor costs research costs under section 174A instead?

Often yes. Section 174A lets a corporation deduct domestic research or experimental costs in the year it pays or incurs them, and it treats any amount paid to develop software as research. Because section 195 excludes these amounts, qualifying US development work does not wait in the start-up pool.

Two conditions make pre-incorporation work less clear:

  • Paid or incurred by the corporation. Section 174A covers the taxpayer's own costs. Work a founder contracted for personally, before the corporation existed, is the corporation's cost only if the corporation takes it on: for example, the contract was made for the company being formed, the code is assigned to it, and it repays the founder. If the founder owned the code and later transfers it, the corporation is acquiring property instead (next sections).
  • Connected with the corporation's trade or business. Section 174A(b) uses this wording. Whether a business that has not launched meets it depends on the facts; settle it with whoever prepares the return.

Work done outside the US is foreign research, spread over 15 years: see software development done abroad. Ongoing developer pay, the option to spread costs out instead, and 2022 to 2024 amounts are in deducting US software development costs. Prototypes and tooling are in deducting hardware research and prototypes.

Should the corporation reimburse a founder, owe a loan, or issue shares?

All three routes can make a cost the corporation's own; they differ in what the founder gets back. Decide and record the route before the first return is prepared.

RouteWhat the corporation recordsWhat the founder gets
ReimbursementPays the founder back against receiptsCash equal to the cost
Loan from the founderA payable to the founder; repayment later is not a deductionA claim for repayment, ideally on written terms
Capital contributionAdded paid-in capital, with or without new sharesHigher basis in the founder's shares

Under each route, the cost is then classified as organizational, start-up or research by what it paid for. The regulation treats shareholders' voluntary pro rata payments to their corporation as an added price for their shares (26 CFR 1.118-1). Whether a founder loan needs interest, and how owners abroad fund the company, is covered in putting money into your US corporation from abroad.

What if a founder contributes code or equipment for shares?

Property contributed for shares is an asset of the corporation, not an expense. When the founders transferring property own at least 80% of the voting power and of the shares of all other classes right after the exchange (section 368(c)), section 351 generally means no gain or loss, and section 362(a) gives the corporation the founder's basis.

  • Basis is the founder's cost, not the value. Code bought from a contractor carries what the founder paid; code the founder wrote alone usually carries little.
  • The founder's own work is not property. Section 351(d)(1) says stock issued for services is not issued for property, so shares for past or future work are taxed as pay.
  • Not an expense. The corporation recovers basis through depreciation or amortization, by the type of asset.
  • Statements are due. A founder holding at least 1% of the stock by vote or value after the exchange (when the stock is not publicly traded), and the corporation, each attach a statement to that year's return (26 CFR 1.351-3).

Costs of the transfer itself are capitalized (26 CFR 1.263(a)-5(a)(5)).

Can founders deduct costs the corporation never repays?

Usually no. The costs belong to the corporation's business, not to a business the founder runs. An unrepaid payment is usually treated as a contribution to capital; the regulation treats shareholders' voluntary pro rata payments as an added price for their shares (26 CFR 1.118-1). That raises share basis and helps only when the shares are sold or become worthless: see deducting shares in a failed startup.

If the corporation never records the cost as a reimbursement, loan or contribution, it has no evidence it bore the cost, and the founder has no clear basis claim either. If the founders worked together for some time before incorporating, see when to incorporate a startup.

Not when paid. Amounts paid to facilitate a stock issuance or a borrowing are capitalized (26 CFR 1.263(a)-5(a)(8) and (9)), and costs of issuing or selling shares are not organizational costs (26 CFR 1.248-1(b)(3)). Costs of a loan are deducted over the loan's term (26 CFR 1.446-5). How stock issuance costs are recovered is left "[Reserved]" (26 CFR 1.263(a)-5(g)(3)), so no later deduction is set out for them.

The same law firm often drafts the charter and the founder stock agreements. Ask for an invoice that splits formation work, which is an organizational cost, from stock issuance work, which is capitalized. Fees for a SAFE or note round are covered in SAFEs and convertible notes.

How is the choice made on the return, and what if the first return missed it?

The corporation is deemed to elect the first-year deduction and amortization for the year business begins; no statement is needed (26 CFR 1.195-1(b); Form 4562 instructions). The amounts go on Form 1120 line 26, and Form 4562 Part VI, line 42, lists amortization that begins that year, with the code section in column (d) (Form 1120 instructions).

  • Opting out: the corporation can instead elect to capitalize the costs on a timely filed return, including extensions. Either choice is irrevocable and covers the whole pool.
  • Missed on one return: the deemed election still applies, so the usual fix is an amended return for that year. The Form 1120 instructions also describe electing on an amended return filed within 6 months of the original due date (excluding extensions), marked "Filed pursuant to section 301.9100-2".
  • Treated wrongly on two or more returns: correcting the category of a cost, or the year business began, is a change in accounting method under sections 446 and 481 (26 CFR 1.195-1(b); 26 CFR 1.248-1(c)), which follows the IRS's method-change procedures.

What records prove each cost?

Keep, for each cost, proof that it was paid, what it bought and that the corporation bore it:

  • Receipts and invoices, with legal bills split between formation and stock issuance work
  • Proof of who paid, from which account, and on what date
  • The date the corporation began business, with the evidence for it
  • Developer and contractor contracts showing who hired them, where the work was done and who owns the result
  • IP assignments from founders and contractors to the corporation
  • A board record adopting the pre-incorporation costs and choosing reimbursement, loan or contribution, and proof of each repayment
  • For contributed property, the founder's cost records and the section 351 statements

Example

These examples are illustrative; figures are in US dollars. Each corporation uses a calendar year.

Formation fees repaid in month two

A founder pays $14,000 of charter, bylaw and state fees before incorporating, plus $3,000 to draft founder stock agreements. The corporation repays $17,000 in its second month, with a board record and receipts. The $14,000 is organizational. It begins business in July: the first return deducts $5,000 plus $300 (6 months of $9,000 ÷ 180), then $600 a year. The $3,000 is capitalized.

A contract developer paid personally

A founder pays a US contractor $60,000 to build the product's first version. If the contract was for the company being formed, the code is assigned to the corporation and the corporation repays the founder, the $60,000 can be the corporation's research cost, deducted in full if the work qualifies. If the founder instead owns the code and contributes it for shares, the corporation holds a $60,000 asset, recovered through depreciation or amortization rather than a research deduction.

Pre-launch research over the limit

A corporation pays $72,000 for market research, travel and consultants before launch. The excess over $50,000 is $22,000, more than $5,000, so the first-year amount is zero. All $72,000 is spread at $400 a month. Business begins in July: $2,400 the first year, $4,800 each full year after. Had business not begun until the next year, the first return would deduct none of it.
