Start-up and organizational costs: what you can deduct in year one

Money spent before a business opens is not deductible in the usual way, because there was no business yet. Instead, special rules let you deduct part of it in the first year and spread the rest. This guide explains what counts and how the deduction works.

Short answer

The startup costs deduction lets you deduct up to $5,000 of start-up costs and $5,000 of organizational costs in the year the business begins. Each $5,000 is reduced once that type of cost exceeds $50,000, and the rest is amortized over 180 months. Start-up costs include market research, pre-opening advertising and training; organizational costs include formation and legal fees.

Organizational costs apply to corporations and to partnerships, including multi-member LLCs. For a single-member LLC, formation costs are generally treated as start-up costs of the owner's business.

How is the deduction worked out?

  1. Total each type of cost

    Start-up costs and organizational costs separately.

  2. Apply the $5,000 limit to each

    Reduced by any amount over $50,000; above $55,000, nothing is deducted immediately.

  3. Amortize the rest over 180 months

    Starting from the month the business begins.

  4. Report on the first return

    Amortization goes on Form 4562; the election is treated as made unless you opt out.

What does an example look like?

A business opening on July 1, 2026 had $12,000 of start-up costs. It deducts $5,000 in 2026. The other $7,000 is amortized over 180 months, about $38.89 a month, so 2026 gets another $233 for six months. The total 2026 deduction is about $5,233.

What is not a start-up cost?

  • Equipment, computers and vehicles, which are depreciated or expensed under Section 179 or bonus depreciation. See Form 4562.
  • Inventory, which becomes cost of goods sold. See cost of goods sold.
  • Costs of issuing shares or selling interests.
  • Costs after the business has started, which are ordinary expenses.

What if the business never opens?

Costs to investigate or start a business that never opened can generally be deducted as a loss if they relate to a specific venture you tried to start, but not if they were general research into whether to go into business at all.
