Section 195 lets you deduct up to $5,000 of startup costs the year you launch, with the rest amortized over 180 months. What counts, what doesn't, and how the phase-out works.
The money you spend getting a business ready to open — market research, scouting trips, pre-launch advertising, training your first hires — isn't immediately deductible the way ordinary business expenses are. Under Section 195, you can deduct up to $5,000 of these startup costs in your first year of business, and the rest gets amortized in equal chunks over 180 months (15 years). A separate, parallel $5,000 allowance covers organizational costs like state formation fees and entity legal work.
The rule sounds simple but hides three timing boundaries that decide everything: when "startup" spending begins, when it ends, and what happens if the business never launches. Get those wrong and deductions either vanish or get stretched over a decade and a half. (Equipment follows different, better rules — more on that below, and in our bonus depreciation and Section 179 playbook.)
Startup costs are amounts you'd deduct as ordinary business expenses if you were already operating, but that you paid before the business actually opened its doors. Typical examples:
Organizational costs are a separate bucket with their own $5,000 allowance: state filing fees, legal fees to draft the operating agreement or bylaws, and accounting fees to set up the entity. If you're forming an entity, our guide on how to incorporate your startup covers the sequence; the tax treatment of those formation fees lands here.
The mechanics, by the numbers:
Example: you spend $30,000 getting a consulting practice off the ground and open in July 2026. You deduct $5,000 immediately; the remaining $25,000 amortizes at about $139 a month — roughly $833 on your 2026 return for July through December, then about $1,667 a year for the next 14-plus years. The deduction is real, but slow. Keeping pre-launch spending lean isn't just good business; it front-loads your tax benefit.
Costs of investigating whether to enter a business at all — general research into an industry before you've committed to a specific venture — qualify as startup costs when they lead to a launched business. Keep records that separate this exploratory phase spending from personal curiosity; a paper trail of a genuine pursuit matters if the venture dies (see below).
The moment the business actually starts operating — you're open, selling, holding yourself out for customers — Section 195 stops applying. From that day forward, the same categories of spending (ads, wages, travel, rent) are ordinary business expenses, deductible in full as incurred. This is why launch date matters: $10,000 of advertising the week before opening is a startup cost amortized over 15 years past the first $5,000; the same campaign the week after opening is fully deductible. Where you have flexibility, spend after you're operational.
Computers, machinery, furniture, and vehicles purchased pre-launch aren't Section 195 costs — they're depreciable assets, and their clock starts when they're placed in service. Once the business is running, they're eligible for Section 179 expensing or 100% bonus depreciation, which usually means an immediate full write-off — far better than 180-month amortization. Small purchases can skip depreciation entirely under the de minimis safe harbor for items up to $2,500. Don't lump equipment into your startup-cost tally; it would only inflate the number toward the $50,000 phase-out while getting worse treatment than it deserves.
Section 195 deductions only exist once an active trade or business begins. If you research, plan, and spend for two years but never open, there's no startup deduction to take. Whether you get anything depends on how far you got:
How you structure the launch matters too. A single-member LLC's startup costs land on your Schedule C once operations begin — our single-member LLC tax guide covers where everything goes on the return.
Timing is the whole game: before launch, costs crawl out over 180 months; after launch, they deduct immediately. Open sooner, spend after.
Mechanically, claiming the deduction is light: you're deemed to elect Section 195 treatment simply by deducting and amortizing the costs on your first return, and the amortization runs on the return's depreciation and amortization schedule from the month operations begin. The heavier lift is the record file behind the numbers:
If you incurred startup costs and simply forgot to deduct them in year one, don't amend by reflex — fixing a missed or incorrect amortization election has its own procedures, and the right path depends on how many returns have been filed since. Raise it with your preparer before touching anything.
Section 195 gives you $5,000 of startup costs and $5,000 of organizational costs immediately (phasing out above $50,000 per bucket), with the balance amortized over 180 months from the month you open. Track pre-launch spending in its own category, keep equipment out of it, and where you can, push discretionary spending past opening day so it deducts in full.
