3. Maintain documentation
Along with categorizing each expense, keep proof as well. Take note of the amount, date, vendor, and business purpose. Save the receipt, invoice, or statement with the entry.
In your miscellaneous expenses account, an entry might look like:
- Amount: $25
- Time: July 14, 2025
- Place: City Parks Dept., New York City
- Category: Park permit
- Business purpose: Little Jimmy’s 4th birthday party at Central Park
This level of detail helps ensure you’re prepared if your accountant or the IRS ever requests supporting documentation for your expenses.
4. Determine total miscellaneous expenses
When it’s time to file your taxes, run a report on your Other expenses account for the year. Add up the small, one-off costs and remove any duplicates, refunds, or personal expenses you’ve accidentally included.
5. Report categorized expenses on Schedule C, Part II
Some items may start in the Other expenses account but later fit a specific category. Move those to the correct account so they appear on the correct line in Part II of Schedule C.
Here are a few common examples:
- Advertising: Line 8
- Legal and professional services: Line 17
- Interest on business loans: Line 16b
- Supplies (non-inventory, used in the same year): Line 22
Remember that bank fees aren’t considered interest, so don’t include them on Line 16b. Record them in a “Bank charges” account in your accounting software instead, or report them with other miscellaneous items in Part V if you don’t have a separate line.
6. Report remaining uncategorized expenses on Schedule C, Part V
Part II of Schedule C includes lines for many types of costs, such as Advertising, Legal, and Professional Services. If there isn’t a line for a particular expense, report it in Part V (Other expenses) instead.
Write each type of expense on its own line with an easy-to-understand label that matches your records, such as “Bank charges,” “Small tools,” and “Regulatory fees.” Add up all the items in Part V and enter the total on Line 48. Copy the Line 48 total to Line 27a (Other expenses) on Schedule C.
You’re now ready to calculate your income for tax purposes. Subtract your total expenses, including Line 27a, from your business income to find your net profit or loss on Line 31. That net amount then carries over to your Form 1040.
