Question: Just started a business, what expenses can I deduct? What Business Expenses Are Fully Deductible vs. Partially Deductible? If you’re a business owner, you’ve probably asked yourself this at least once: “Can I write this off?” As a tax professional, I hear it all the time. While it may seem like a simple yes or no answer, the truth is that not all business expenses are treated equally when it comes to deductions. Some expenses are fully deductible, meaning you can write off 100% of the cost. Others are only partially deductible due to IRS limitations. And then there are a few that might surprise you with how little (or how much) you can actually claim. Fully Deductible Expenses: The Everyday Essentials Many of the expenses you incur while running your business are completely deductible. These are your bread-and-butter costs—necessary, ordinary expenses that keep your operations going. Some examples include the following: Office supplies, internet bills, software subscriptions, and utility costs tied to your workspace Professional services like bookkeeping, legal help, or tax preparation fees Paying employees along with your share of payroll taxes and benefits Renting an office or leasing equipment exclusively for your business
