Deducting Business Startup Costs

Yes — but not all at once. The money you spend before you ever open your doors (market research, legal fees to set things up, a first round of advertising, training) is treated by the IRS as a startup cost, and the tax code puts it in a special category. You generally can't just write the whole amount off the moment you open. Instead, federal law lets you deduct a limited amount in your first year of business and requires you to spread ("amortize") whatever's left over a period of years. The exact dollar amount you can deduct up front, and the point at which that first-year deduction starts shrinking, are set by statute and can change — always confirm the current figures on irs.gov before you file, rather than relying on a number you saw somewhere else (including this page).

The basic rule: capitalize, but with a break

Normally, money spent to create a business — as opposed to running one you already have open — is a capital expense. Capital expenses don't get deducted immediately; they get recovered over time. Section 195 of the Internal Revenue Code carves out a break for start-up expenditures: it lets a new business deduct a limited amount of those costs in the year the business begins, and amortize the rest ratably over a fixed number of months (currently a 15-year, 180-month schedule) starting the month the business actually opens.

Two things make this different from an ordinary business expense:

• The first-year deduction is capped — and the cap phases out, dollar for dollar, once your total start-up costs pass a certain threshold. Spend enough before opening and the first-year deduction can disappear entirely, leaving everything to be amortized.
• Both the cap and the threshold are set by Congress, not adjusted automatically each year, and have changed with past legislation — don't assume a number you remember is still accurate. Confirm current amounts on irs.gov and in the instructions to IRS Form 4562 (Depreciation and Amortization), the form you use to claim the deduction and amortization.

What counts as a start-up cost

Generally, a cost counts if it's something you paid or incurred while investigating or creating your business, before it was actually up and running, and it's the kind of expense that would be currently deductible if you'd incurred it after opening. Common examples include:

• Market and feasibility research — surveys, analysis of potential customers, locations, or suppliers
• Travel and consulting costs to line up suppliers, distributors, or customers before you open
• Training employees before the business begins operating
• Legal and professional fees connected with getting the business set up (accounting fees for setting up your books, for example)
• Advertising to announce the opening of the business
• Salaries and wages for employees being trained before opening

State formation costs you pay to set up the entity — filing fees, registered-agent fees, and similar charges from your state's business filing agency — are real costs of starting up, but the amounts vary by state and by entity type, so you'll need to check with your own state's Secretary of State or equivalent filing office rather than relying on a number from another state.

What doesn't count

Not everything you spend before opening falls into this bucket:

• Equipment, vehicles, and other tangible property you buy for the business are recovered separately, through depreciation rules (and possibly Section 179 expensing or bonus depreciation). Those limits are adjusted periodically — confirm current figures on irs.gov rather than assuming last year's numbers still apply.
• Interest, taxes, and research-and-experimental costs follow their own, separate deduction rules.
• Ongoing operating costs once the business is open — rent, ordinary advertising, supplies — are simply current business expenses, deducted the year you incur them, like any established business.
• Costs of acquiring a specific existing business (versus researching whether to acquire one) are capital costs of the assets you're buying, not start-up costs.

Forming an LLC, corporation, or partnership: a related but separate rule

If you're forming a corporation or a partnership (including a multi-member LLC taxed as a partnership), the costs of legally creating that entity — state filing fees, fees for drafting organizational documents, and similar costs — are "organizational costs," governed by a close cousin of the start-up rule (Section 248 for corporations, Section 709 for partnerships). The mechanics run in parallel: a limited first-year deduction, phased out above a threshold, with the remainder amortized over the same 180-month period. A single-member LLC that's disregarded for tax purposes (the default unless you elect corporate taxation) doesn't have a separate organizational-cost category — its formation costs are typically evaluated under the ordinary start-up rule instead. Because entity choice changes which rule applies and interacts with liability and self-employment tax questions beyond this deduction, run it past a CPA or tax preparer, especially in your first year.

You have to actually open the business

This trips people up: the start-up cost deduction is only available once your business actually begins operating as an active trade or business. If you spend money investigating a venture and then decide not to go forward, those investigatory costs generally can't be deducted or amortized as start-up costs at all under this provision — an abandoned venture gets a different, more limited tax treatment. If you do go forward, the clock for amortizing the non-deducted portion starts running in the month your active trade or business actually begins, not the month you started spending money or filed your formation paperwork.

What to do

1. Track pre-opening expenses separately, from day one. Keep receipts and a simple log of what you spent before you opened and why — market research, formation fees, pre-opening advertising, training. Don't lump these in with regular expenses once you're running; they're a different category for tax purposes.
2. Note the date your business actually began operating. That date matters — it's when your amortization period starts and it's the year you claim the first-year deduction.
3. File Form 4562 with your first business tax return (Schedule C for a sole proprietor, or the applicable corporate or partnership return) to claim the deduction and start amortizing the remainder. The election is generally treated as automatic once claimed on a timely return, but the deadline for making or changing it ties to your filing deadline (including extensions) — confirm current timing on irs.gov or with a tax preparer.
4. Separate start-up costs from equipment purchases. A computer, tools, or a vehicle bought for the business is depreciation, not a start-up cost — keep those receipts in their own category too.
5. Confirm the current-year dollar limits before you file. Search irs.gov for start-up expenditures, or check the Form 4562 instructions, for the first-year cap and phase-out threshold in effect for the year your business began.
6. Get help if your start-up spending was significant, or you formed a corporation or partnership. A CPA or enrolled agent can make sure you're capturing every deductible pre-opening cost and applying the organizational-cost rules correctly. Free help is also available through SBA resource partners, Small Business Development Centers, and SCORE mentors.

Once your business is open, a different set of obligations kicks in — you'll generally owe self-employment tax (the combined Social Security and Medicare tax self-employed people pay both halves of) and, in most cases, quarterly estimated payments, since no employer is withholding for you. If a venture doesn't work out and leaves business debt behind, that's a separate topic this site covers elsewhere. And protecting a business name or logo is its own question, handled through the USPTO, beyond the tax treatment covered here.

FAQ

Do I need to make a special election to deduct start-up costs?

In most cases the deduction and amortization are treated as automatically elected once you claim them on a timely filed return for the year the business begins, without a separate statement attached. Confirm the current procedure on irs.gov or with a tax preparer before you file.

What if my total start-up costs are small?

If your costs stay well under the phase-out threshold, you may be able to deduct all of them in your first year rather than amortizing any portion — but confirm the current threshold on irs.gov, since it's set by law and can change.

Can I deduct the cost of researching a business I decided not to start?

Generally, no — not under the start-up cost rules, which only apply once you actually go into business. Costs from a venture you investigated and abandoned are treated differently and are often not deductible at all. Bring this to a tax professional if it applies to you.

Is my LLC formation fee a start-up cost or an organizational cost?

It depends how your LLC is taxed. A single-member LLC taxed as a disregarded entity typically treats formation costs under the general start-up rule. A multi-member LLC taxed as a partnership, or an LLC that's elected corporate taxation, generally falls under the organizational-cost rules instead. Either way, the state filing fee varies by state — check your state's business filing office for the current amount.

Does buying equipment before I open count as a start-up cost?

No. Equipment, vehicles, and other tangible business property are recovered through depreciation (and possibly Section 179 expensing or bonus depreciation), not the start-up cost deduction, even if bought before opening.
