Startup Costs: What You Can Deduct in Your First Year

Starting a new business? The IRS allows you to deduct up to $5,000 in startup expenses in your first year, such as:

  • Business formation fees
  • Legal and accounting services
  • Marketing and research costs

Did you know? Expenses exceeding $5,000 can still be deducted — but they need to be amortized over several years.

Keep accurate records of all your initial expenses so you can maximize this deduction. If you're not sure how to categorize a startup cost, that's exactly the kind of thing clean bookkeeping (and a quick question to your accountant) solves before it becomes a missed deduction.
