Start-up costs get a friendlier tax break than most new business owners expect: you can deduct up to $5,000 immediately in your first year, with the remainder spread out over time. Here's exactly how IRC Section 195 splits that deduction, and what changes the math.
- IRC Section 195 lets you deduct up to $5,000 of start-up costs in your first year of business.
- The $5,000 deduction phases out dollar-for-dollar once total start-up costs pass $50,000 and disappears at $55,000.
- Anything not deducted immediately gets amortized in equal amounts over 180 months (15 years).
- Organizational costs (forming an LLC or corporation) get a separate $5,000 deduction under a related rule.
- A registered ScholarTax preparer can help you claim the right amount on your first-year return.
Why this matters
Most new business owners assume every dollar spent before opening day is a lost write-off, or that it all has to wait until they file a return years later. Neither is true. IRC Section 195 exists specifically to give new businesses an immediate deduction, then spreads the rest across a predictable schedule so you're not stuck front-loading a tax bill in year one. Get the amount wrong, and you either leave money on the table or trigger a mismatch the IRS will flag. Get it right, and it's one less thing keeping you up before your first filing deadline.
How much can I deduct right away under IRC Section 195?
The answer depends entirely on your total start-up spending before your business opened its doors. Here's the breakdown:
| Total start-up costs | Immediate deduction | Remaining balance |
|---|---|---|
| $50,000 or less | $5,000 | Amortized over 180 months |
| $50,001 to $54,999 | $5,000 minus the excess over $50,000 | Amortized over 180 months |
| $55,000 or more | $0 | Full amount amortized over 180 months |
Start-up costs cover the investigative and pre-opening expenses a business normally deducts once it's operating: market research, travel to scout locations, employee training before the doors open, and professional fees paid to set things up. The catch is timing. Section 195 only applies to costs paid before the business is actively running. Once you're operational, ordinary expenses get deducted the normal way, no amortization needed.
Start-up costs under $50,000: full $5,000 deduction
If your total qualifying start-up spending sits at or below $50,000, you deduct the full $5,000 in your first tax year of operation. The remaining balance, whatever's left after that $5,000, gets amortized in equal monthly installments over 180 months, starting the month your business begins active operations.
Start-up costs between $50,000 and $55,000: reduced deduction
Once total start-up costs cross $50,000, the immediate deduction shrinks dollar-for-dollar. Spend $52,000 and your immediate write-off drops to $3,000. Spend $54,500 and you're down to $500. The math is simple: subtract the excess over $50,000 from the $5,000 cap.
Start-up costs over $55,000: no immediate deduction
At $55,000 or more in total start-up costs, the phase-out eliminates the immediate deduction entirely. Every dollar gets amortized over the 180-month schedule instead. That's still a real tax benefit, just a slower one: a $60,000 start-up bill translates into roughly $333 a month in deductions once the amortization period begins.
Why your start-up deduction varies
A handful of factors decide where your business lands on that table:
- Total dollar amount of qualifying costs. Everything hinges on whether you're under, inside, or above the $50,000 to $55,000 phase-out band.
- When your business is treated as "active." Costs paid before you're operating qualify as start-up costs; costs paid after are ordinary deductible expenses, no amortization involved.
- Organizational costs are separate. Forming an LLC, partnership, or corporation triggers its own $5,000 deduction under a related IRC provision, with its own phase-out at the same thresholds. These don't get lumped in with start-up costs.
- Your election isn't automatic in every case. The deduction and amortization generally kick in once you claim start-up costs on your return for the year the business begins; how you document that matters for your records.
- The 180-month clock starts when the business begins, not when you paid the expense. Spend money in 2025 but open in 2026, and amortization begins with your 2026 activity.
- State tax treatment can differ from the federal rules above, so the math on your federal return won't always match your state return dollar for dollar.
Related questions about IRC Section 195
What counts as a start-up cost under Section 195?
Start-up costs are the expenses you'd normally deduct once your business is running, but which you paid before it actually opened. That includes market research, scouting and evaluating potential business locations, advertising for the opening, and training employees before launch. It does not include costs to acquire depreciable business property or costs tied to forming the entity itself, those fall under organizational costs instead.
Are organizational costs different from start-up costs under Section 195?
Yes. Organizational costs, like legal and state filing fees to form an LLC or corporation, get their own $5,000 immediate deduction with the same $50,000 to $55,000 phase-out, but under a separate provision from Section 195. You track and elect the two categories independently, even though the dollar limits look identical.
What happens if I never actually start the business?
If you spend money investigating a business but never launch it, those investigative costs generally aren't deductible as start-up costs at all, they're treated as a personal capital loss instead, and only in narrow circumstances. This is one of the sharper edges of Section 195: the deduction exists only once a business actually begins operating.

FAQ
How much can I deduct under IRC Section 195 in 2026?
You can deduct up to $5,000 of start-up costs immediately in 2026 if your total qualifying costs are $50,000 or less. Above that threshold, the deduction phases out dollar-for-dollar until it hits zero at $55,000.
How long is the amortization period for business start-up costs?
The amortization period is 180 months, or 15 years, starting the month your business begins active operations. Any start-up costs not deducted immediately get spread evenly across that schedule.
Can I deduct start-up costs before my business officially opens?
No, Section 195 only lets you deduct or amortize costs once the business begins active operations. Costs paid before that point are tracked and applied starting in the year the business actually starts.
Is the $5,000 start-up deduction the same as the organizational cost deduction?
No, they're separate deductions under different IRC provisions, even though both cap at $5,000 and phase out at the same $50,000 to $55,000 range. Start-up costs cover operational setup expenses; organizational costs cover forming the legal entity.
What if my start-up costs are over $55,000?
At $55,000 or more, the immediate $5,000 deduction is fully phased out, and every dollar of start-up cost is amortized over 180 months instead. You still get the full deduction, just spread across 15 years rather than taken up front.
Do I need to make an election to claim start-up cost deductions?
Generally yes, you claim the deduction and amortization by reporting start-up costs on your return for the year the business begins. Keeping documentation of what you spent and when is what a preparer checks first.
Does IRC Section 195 apply to sole proprietors or just corporations?
IRC Section 195 applies to any taxpayer starting a trade or business, including sole proprietors, partnerships, and corporations. The $5,000 cap and $50,000 phase-out threshold apply the same way regardless of entity type.
One last thing
The part most new business owners miss isn't the $5,000 cap, it's the phase-out cliff at $55,000. Spend $54,900 on start-up costs and you still get a small deduction; spend $55,100 and you get nothing immediately, just the 180-month amortization. If you're close to that line in 2026, timing a few purchases into the following tax year can be the difference between a deduction now and one stretched across 15 years.
