Keeping track of business income and expenses can be overwhelming\u2014especially if you\u2019re rushing to do it so you can file your taxes. Slow and steady is the best way to keep on top of these figures\u2026 but we know it doesn\u2019t always happen that way. You start the year off with good intentions, then suddenly it\u2019s tax season and you\u2019re looking at a pile of receipts you definitely meant to scan and file months ago.<\/p>\n

Depending on how your business is classified, you will need to file different forms and returns. At Tree City Tax, we work with sole proprietors who will file a Schedule C.<\/p>\n

This article will guide you through form Schedule C so you can capture all of your relevant business expenses. This is a general guide, so if you have questions please contact your tax preparer, accountant, or schedule a consultation<\/a> with us to get clarification.<\/p>\n

Schedule C Part I: Income<\/h2>\n

Just a quick note before we dig into the expenses and deductions portion of the form\u2014you\u2019ll need to keep track of all income, especially if you have multiple revenue streams. Payment processors like PayPal and Stripe should issue you a 1099-K that you can check your numbers against.<\/p>\n

Contract clients will need to issue you a 1099-NEC if they paid more than $600 to you in 2025. They\u2019ll also file this with the IRS, so make sure you reflect all 1099 forms in your return.<\/p>\n

If you sell physical products, you\u2019ll report the Cost of Goods Sold (COGS) in this section as well, which is subtracted from your gross revenue to determine your profit. Part III of Schedule C walks you through the COGS calculations.<\/p>\n

Schedule C Part II: Expenses<\/h2>\n

Here\u2019s where it gets fun. Each box in Part II asks about a different type of expense. You can use this part of the tax form to create your expense bookkeeping documents throughout the year, then just plug the totals into each line on the form. Let\u2019s explore each expense to make sure you\u2019re including all possible deductions.<\/p>\n

Advertising (Line 8):<\/strong> Advertising costs including digital ads (Google search ads, Facebook or Instagram ad campaigns, etc.), print advertising costs (running an ad in the local newspaper, flyers, business cards, signage, branded packaging, etc.), giveaway prizes, or sponsorships. You can also include the cost of sending cards to clients if the mail is meant to promote the business or build relationship with your clients.<\/p>\n

This list isn\u2019t exhaustive\u2014check with your tax professional to see if your expenses fall under the advertising umbrella.<\/p>\n

Car and Truck Expenses (Line 9): <\/strong>As a business owner, you can deduct the actual expenses of operating your vehicle\u2014including gas, oil, repairs, insurance, registration, etc.)\u2014or take the 2025 standard mileage rate of $0.70 per mile as your deduction for line 9.<\/p>\n

Commissions and Fees (Line 10): <\/strong>Fees that are not capitalized or deducted elsewhere on your tax return can be listed on line 10 of your Schedule C. There are special considerations if these fees are paid to facilitate the sale of property, so if you\u2019re in real estate you\u2019ll want to consult your tax pro.<\/p>\n

Fees paid to payment processors like PayPal or Stripe can be listed under Other Expenses in Part V, then totaled and recorded on line 27a.<\/p>\n

Contract Labor (Line 11): <\/strong>Payments made to contractors or freelancers that are not employees <\/em>can be listed on line 11. If you paid more than $600 to a contractor, you\u2019ll need to file a form 1099-NEC with the IRS and provide a copy to the contractor.<\/p>\n

Depletion (Line 12): <\/strong>Depletion refers to the use of natural resources via mining, quarrying, drilling, or cutting. This line applies to businesses with an economic interest in mineral property or standing timber, and it allows the business to account for the reduction of material in reserve for future collection.<\/p>\n

Depreciation (Line 13): <\/strong>Depreciation applies to the purchase of equipment or property that will be in use by the business for multiple years. Each year, you can depreciate a percentage of the purchase, or in some cases you may elect to expense the entire cost at once.<\/p>\n

Insurance (Line 15): <\/strong>Business insurance premiums can be deducted on line 15, including property coverage, liability insurance, car insurance for business vehicles, and any other insurance used to operate your business.

Legal and Professional Services (Line 17): <\/strong>Any fees charged by accountants, bookkeepers, lawyers, tax preparers, and other professional services that are necessary to operate your business are listed on line 17.<\/p>\n

Office Expenses (Line 18): <\/strong>If you\u2019re somebody who loves to browse the aisles at Staples, this business expense may feel like you\u2019re a kid in a candy store. You can deduct the cost of office supplies and stamps\/postage as long as they are \u2018ordinary and necessary\u2019 for your business and not for personal use. Common supplies in this category are printer ink and paper, paper clips, pens, janitorial supplies, notepads and sticky notes, etc.<\/p>\n

You may even be able to expense supplies like microphones and cameras if recording audio\/video is part of your business\u2014just make sure you\u2019re not also using them for personal, non-business tasks.<\/p>\n

Rent or Lease Costs (Lines 20a-20b): <\/strong>The cost of renting or leasing a vehicle, machinery, or equipment can be expensed on line 20a, while rent for office space or other property goes on line 20b. You may only expense the amount that was for business use.<\/p>\n

Repairs and Maintenance (Line 21): <\/strong>Any incidental repairs and maintenance costs can be expensed on line 21 if they do not add appreciable value.<\/p>\n

Supplies Not Included in COGS (Line 22): <\/strong>Materials, supplies, and equipment that get used within a year can be deducted on line 22. If the usefulness of these supplies is long-term, you likely need to depreciate them. Once again, when in doubt, ask your tax pro!<\/p>\n

Taxes and Licenses (Line 23): <\/strong>Tax and license costs of operating your business can be expensed, including sales tax, property taxes on business assets, regulatory fees for licensure, social security and Medicare taxes paid to match employee withholding, federal unemployment tax, and federal highway use tax.

Other Expenses (Line 27a): <\/strong>Any other expenses not deducted elsewhere on your Schedule C can be listed in Part V of the form on line 48 (and copied to line 27a).

Businesses with Employees<\/h3>\n
