If you file a Schedule C as a sole proprietor or single-member LLC, you already know how detailed the IRS can be. The Schedule C form requires a thorough breakdown of your business income and expenses, leaving little room for guesswork. Schedule C is the primary IRS form used to report your business’s profit or loss and completing it accurately is essential for both compliance and tax planning.
To make this task easier for you (and cleaner for us), we’ve created a simple Excel worksheet you can download, fill out, and upload through your Senter CPA portal as part of your organizer.
How the worksheet helps
- Gives you one place to report all Schedule C income and expense information
- Matches the main categories on Schedule C so we can easily reconcile the information when preparing your return
- Cuts down on back-and-forth emails regarding missing items
How to use it
- Download the Schedule C Excel worksheet from this post.
- Fill it out as completely as you can based on your records.
- Log in to your Senter CPA portal.
- Upload the finished file under your 1040 organizer in the Document Upload area for business income.
Please do not email it. Uploading through the portal keeps everything together with the rest of your tax documents.
What if I already use accounting software or my own spreadsheet?
If you already track your business in:
- QuickBooks, Xero, Wave, or another system, or
- Your own spreadsheet that clearly shows income and expenses
You can upload those reports instead of using our worksheet. For example, a year-to-date Profit & Loss, access to your QuickBooks file plus any supporting detail is fine.
