Title 26 › Subtitle A — Income Taxes › CHAPTER 1 — NORMAL TAXES AND SURTAXES › Subchapter B — Computation of Taxable Income › PART VI — ITEMIZED DEDUCTIONS FOR INDIVIDUALS AND CORPORATIONS › § 195
You can choose to deduct some start-up costs when your business begins. If you make that choice, you may immediately deduct up to the smaller of your total start-up costs or $5,000, but that $5,000 drops dollar-for-dollar once your start-up costs go over $50,000. Any remaining start-up costs are spread out and deducted evenly over 180 months starting the month your business begins. For tax year 2010 only, the immediate amount was $10,000 and the cutoff was $60,000. If you sell or close the whole business before the 180 months end, any leftover deferred costs can be deducted if they qualify under section 165. Start-up costs are amounts paid to investigate, create, buy, or prepare for a business, or to carry on activities before the business actually starts. Costs already deductible under sections 163(a), 164, 174, or 174A are not start-up costs. When the business begins is set by IRS rules, but if you acquire a business it begins when you buy it. You must make the election by the time you file the tax return for the year the business starts (including extensions), and the choice applies to that year and all later years.
