Business start-up and organizational costs are generally capital expenditures. However, you can elect to deduct up to $5,000 of business start-up and $5,000 of organizational costs paid or incurred after October 22, 2004. The $5,000 deduction is reduced by the amount your total start-up or organizational costs exceed $50,000. Any remaining costs must be amortized. For information about amortizing start-up and organizational costs, see chapter 8.
Start-up costs include any amounts paid or incurred in connection with creating an active trade or business or investigating the creation or acquisition of an active trade or business. Organizational costs include the costs of creating a corporation. For more information on start-up and organizational costs, see chapter 8.taxmap/pubs/p535-035.htm#en_us_publink1000144872
You elect to deduct the start-up or organizational costs by claiming the deduction on the income tax return (filed by the due date including extensions) for the tax year in which the active trade or business begins. However, if you timely filed your return for the year without making the election, you can still make the election by filing an amended return within 6 months of the due date of the return (excluding extensions). Clearly indicate the election on your amended return and write "Filed pursuant to section 301.9100-2." File the amended return at the same address you filed the original return. The election applies when computing taxable income for the current tax year and all subsequent years.
