Business Startup Costs: The IRC 195 Deduction for New Business Expenses
Expenses incurred before a business begins operations are not immediately deductible as regular business expenses. Instead, they are “startup costs” under IRC 195 and receive special treatment: the first $5,000 is deductible in the year the business begins, and the remainder is amortized over 180 months (15 years). The $5,000 immediate deduction is reduced dollar-for-dollar when total startup costs exceed $50,000, and is eliminated entirely when startup costs exceed $55,000.
Startup costs are expenses that would be deductible as ordinary business expenses IF the business were already operating. They include: market research and analysis, advertising for the business opening, training for employees (before the business opens), travel to establish suppliers or customer relationships, professional fees for setting up the business (attorney, accountant, consultant), rent paid before opening (if the space is leased before the business begins operating), and wages paid to employees during the training period before operations begin. Startup costs do NOT include: the cost of purchasing or constructing business assets (those are capitalized and depreciated), organizational costs for forming the entity (those are handled separately under IRC 248/709), or personal living expenses during the startup period. The key date is when the business “begins”: the business begins when it starts the activities for which it was organized (selling products, providing services). Pre-revenue activities like setting up the office, training staff, and marketing before the first sale are the startup period.
How does the deduction work?
What’s NOT a startup cost?
Expenses incurred after the business begins operations are regular business expenses, deductible in full in the year paid (cash method) or incurred (accrual method). The startup cost rules only apply to expenses incurred BEFORE the business begins.
Equipment purchased before opening (grooming tables, gym equipment, construction tools) is not a startup cost. It is a capital expenditure, deductible under Section 179 or depreciated under MACRS, starting when the asset is placed in service.
Organizational costs (filing fees for LLC formation, state registration fees, operating agreement preparation) are handled under IRC 248 (corporations) or IRC 709 (partnerships), with the same $5,000 immediate deduction and 180-month amortization structure.
What about businesses that never open?
If the business is investigated but never actually starts (the owner abandons the idea before operations begin), the startup costs are not deductible at all under IRC 195. However, the costs may be deductible as a loss under IRC 165 in the year the business plan is abandoned. This requires that the owner can demonstrate a genuine profit motive and that the expenditures were made in connection with a trade or business (not a hobby or personal interest).
Can I deduct startup costs before my business earns any revenue?
Under IRC 195, you can immediately deduct up to $5,000 of startup costs in the year your business begins operating, with the remainder amortized over 180 months (15 years). The $5,000 immediate deduction phases out dollar-for-dollar once total startup costs exceed $50,000. Startup costs include market research, travel to investigate the business, advertising before opening, employee training before operations begin, and professional fees for setting up the entity. The key requirement is that the business must actually begin operating; costs for a business you investigated but decided not to pursue are generally not deductible. The amortization period starts in the month the business opens its doors to customers, not when you began incurring costs.
