LLC Startup Cost Deduction Guide — $5K Immediate Deduction & 180-Month Amortization (2026)

1. Identify and list all startup costs before the business opened Startup costs are pre-opening expenses — costs paid or incurred before the LLC began active operations (before you were open for business and ready to accept customers). Go through your bank statements and credit card records for the period from when you first began investigating or preparing to launch your business through the day before you began active operations. Categorize each expense: (a) qualifying §195 startup costs (market research, pre-opening advertising, training, consulting, business plan costs); (b) organizational costs (state filing fees, attorney fees for LLC formation documents — tracked separately); (c) capital expenditures (equipment, vehicles, leasehold improvements — depreciated under MACRS); (d) personal expenses (not deductible). Subtotal the qualifying §195 startup costs — this is your IRC §195 amount.
2. Calculate the immediate deduction and the amortizable remainder Apply the phase-out: (a) If total §195 startup costs are $50,000 or less: immediate deduction = $5,000; amortizable amount = total startup costs minus $5,000. (b) If total §195 startup costs are $50,001–$54,999: immediate deduction = $5,000 minus (total minus $50,000). Example: $52,000 in startup costs → $5,000 − $2,000 = $3,000 immediate deduction; amortizable amount = $52,000 − $3,000 = $49,000. (c) If total §195 startup costs are $55,000 or more: no immediate deduction; amortize the entire amount over 180 months. Organizational costs (LLC formation costs) have a separate $5,000 immediate deduction and the same $50,000 phase-out threshold under IRS Rev. Proc. 2011-11 — calculate them independently.
3. Determine the start date for amortization Amortization begins in the month the LLC begins active operations — the date the business first opens for business and is ready to accept customers, not the formation date. Example: LLC formed January 15, equipment purchased February–April, employee training completed in May, first customer served June 1. Amortization begins June 1. The first year's amortization is prorated: if the business opens in month 6 of the year, you amortize 7 months' worth of the annual amount (months 6 through 12). Monthly amortization = total amortizable startup costs ÷ 180 months.
4. Report on your tax return (Schedule C and Form 4562) Immediate deduction: report on Schedule C, Part V (Other Expenses), line 48, with description 'IRC §195 startup cost deduction.' Amortizable amount: report on Form 4562, Part VI (Amortization). Enter: description ('Startup costs — IRC §195'), the amortization start date (month/year the business began active operations), the total amortizable amount, the code section (195), the amortization period (180 months), and the current year amortization deduction. Form 4562 total flows to Schedule C. In year 2 through year 15, report the same annual amortization amount on Form 4562 each year until fully amortized. The election to amortize is automatic (Rev. Proc. 2011-11) — no separate statement is required, but describe the deduction clearly on Form 4562.
5. Handle organizational costs separately Organizational costs (state LLC filing fees, attorney fees for the operating agreement, filing fees for the EIN) are governed separately from §195 startup costs. Under the same automatic election (Rev. Proc. 2011-11), organizational costs are treated identically: $5,000 immediate deduction (with the same $50,000 phase-out threshold), and the remainder amortized over 180 months beginning with the month the LLC is formed. Organizational costs and startup costs have separate $5,000 limits — a company can claim up to $5,000 immediate deduction for each category independently in the same year. Report organizational cost amortization on Form 4562, Part VI, with code section 709 (for partnerships) or 248 (for corporations). Note: the LLC filing fee paid to the state is an organizational cost, not a startup cost — track them in separate categories.
6. If the business never opens, handle the loss on abandoned startup costs If the LLC investigates starting a business, incurs startup costs, and then decides not to proceed (or the business fails before opening), the startup costs may be deductible as an ordinary loss under IRC §165(c)(2) in the year you abandon the business effort. The key requirement: you must have been investigating a specific business opportunity with an actual profit motive — not just general exploration. Document your intent, the specific opportunity investigated, and the decision to abandon it. Abandonment losses from specific business investigations are fully deductible against ordinary income, not subject to capital loss limitations.
