How to Deduct Business Startup Costs
Most of what you spend before opening is deductible, but the rules are specific. Here is how the Section 195 startup deduction works, the 5,000 dollar first-year write-off, and the phase-out that surprises bigger launches.
Under Section 195 you can elect to deduct up to 5,000 dollars of startup costs the year your business opens, with the rest amortized over 180 months (15 years). That 5,000 dollar write-off shrinks once total startup costs pass 50,000 dollars.
Key takeaways
- Deduct up to 5,000 dollars in the first year; anything beyond amortizes evenly over 15 years.
- The 5,000 dollar immediate deduction drops dollar-for-dollar above 50,000 dollars of startup costs and disappears entirely at 55,000 dollars.
- Startup costs are investigating and getting ready to open (market research, pre-launch advertising, training, travel, professional fees); equipment is depreciated and inventory becomes COGS.
- The deduction is tied to the day your business actually begins; costs after that day are ordinary business expenses.
First-year startup deduction (Section 195)
| Total startup costs | First-year deduction |
|---|---|
| 50,000 dollars or less | Up to 5,000 dollars |
| 51,000 dollars | 4,000 dollars (reduced dollar-for-dollar) |
| 55,000 dollars or more | 0 dollars (all amortized over 15 years) |
Before a business earns its first dollar, it usually spends a few. Market research, a logo, legal advice, the trip to meet a supplier, all of it adds up before you are technically open. The good news is the tax code lets you deduct a lot of that, but the rules are specific and easy to get wrong. Here is how the startup cost deduction actually works under Section 195.
The 5,000 dollar first-year deduction
You can elect to deduct up to 5,000 dollars of startup costs in the year your business actually opens for business. Anything beyond that gets spread out, or amortized, evenly over 180 months, which is 15 years. So a modest launch often lets you write off most or all of your startup spending right away, while a bigger one means deducting a chunk now and the rest slowly over time.
The catch above 50,000 dollars
That 5,000 dollar immediate deduction is not unlimited. It shrinks dollar-for-dollar once your total startup costs pass 50,000 dollars. Spend 51,000 and your first-year deduction drops to 4,000. Spend 55,000 or more and the immediate deduction disappears entirely, leaving the whole amount to be amortized over those 15 years. It is a detail that surprises people who launch something capital-heavy.
What counts, and what doesn't
Startup costs are the expenses of investigating and getting ready to open: market research, advertising before launch, training, travel to line up suppliers or customers, and professional fees. What does not count is just as important. Equipment, vehicles, and other long-lived property are depreciated separately, often using Section 179 or bonus depreciation, and inventory becomes part of your cost of goods sold. Those are not startup costs.
- Deductible startup costs: research, pre-opening advertising, training, supplier travel, consulting and legal fees.
- Not startup costs: equipment and vehicles (depreciated), inventory (cost of goods sold).
- The clock starts when your active business begins, not when you spent the money.
Timing is everything
The deduction is tied to the day your active trade or business begins. Costs before that day are startup costs under these rules. Costs after that day are ordinary business expenses you deduct normally. So pinning down when you really opened matters, and keeping clean records of every pre-launch expense is what makes the deduction defensible. These all land on your Schedule C at tax time.
Capture every pre-launch dollar
Track your startup spending from the very first expense, categorized and with receipts attached, so the deduction is ready and defensible when your business opens.
Start freeHow Vuuv helps
The startup deduction is only as good as your records of what you spent before opening. Vuuv lets you capture those early costs as they happen, sorted into categories with receipts attached, so nothing from the pre-launch scramble gets lost. When your first tax season arrives, those organized expenses feed the Schedule C report Vuuv generates, and you are not trying to reconstruct a year of getting started from a pile of receipts.
