Track LLC expenses without pretending it is a tax return

An LLC does not need a new app because it has a letterhead. It needs a list of what came in, what went out, and which bucket each expense belongs in, kept all year so April is not a shoebox. That list is bookkeeping hygiene. It is not a tax return, and it is not tax advice.

What follows is an organizational method for a solo operator or a very small company with one set of books. If you have employees, inventory, or several entities, you are past a single sheet. Nothing here tells you what you may deduct. A qualified tax professional does that. Category names that resemble Schedule C Part II lines are a filing aid you can edit. They change when the form changes. Do not treat a spreadsheet label as a legal conclusion.

Income and expenses are different lists

Keep income out of the expense rows. A client payment is not “negative advertising.”

Income columns worth having:

• Date received
• Who paid
• What it was for (invoice number if you have one)
• Amount
• Note

Expense columns:

• Date
• Vendor
• Amount
• Category
• How you paid (card, bank, cash, personal card you need to reimburse)
• Note, including a receipt pointer if you have one

If you pay a business cost on a personal card, log it the day you pay and mark the method. Forgetting those rows is how people understate costs and then argue with their own memory.

Categories that sound like the form, and why they are editable

US sole proprietors often sort expenses into lines that resemble Schedule C Part II: advertising, car and truck, contract labor, insurance, legal and professional, office expense, rent, repairs, supplies, taxes and licenses, travel, meals, utilities, wages, and other. An LLC taxed another way may not file Schedule C at all. Use the labels as a sorting guide you can rename. If your accountant wants a different chart, change the list in January and do not invent a second list in June.

Rules that keep the year clean:

• One category per expense. If a store run was supplies and a meal, use two rows.
• Meals are not “other” just because the rule is annoying. Put them in meals and let your preparer decide the treatment.
• Sales tax you collected for a state is not your income and not a casual expense. Ask your preparer where it belongs. Do not hide it in supplies.
• A category called “other” with no monthly cap will swallow the year. Split it when it gets large.

This mapping is a guide only. It may be wrong for your facts. It does not constitute tax advice.

The monthly view

Once a month, read four totals. Not forty.

• Income for the month
• Expenses by category
• Total expenses
• Net, income minus expenses

A chart of categories shows whether “software” quietly became a second rent. It does not show whether a cost is deductible.

Example, fictional, one month:

That net is not “what you can spend,” not “profit after tax,” and not a draw. It is income minus the expenses you logged. If you are behind on logging, the net is fiction. If you paid yourself, decide with your preparer whether that payment is a wage row, a draw that is not an expense, or something else. Do not guess in the sheet and call it done.

Hand the year view to your accountant as a clean export: every expense row, totals by category, income, and the monthly nets. They will still ask questions. The point of the file is that you can answer with a row instead of a camera roll.

A Friday habit for a one-person shop

1. Photograph or save receipts the day they happen, even if you type them later.
2. Once a week, type anything still in the camera roll. Waiting until the quarter is how categories get sloppy.
3. Anything paid from a personal account gets the method flag the same week.
4. At month end, read the category totals and the net. If one vendor looks wrong, fix the row before you close the month.
5. Do not delete a row to “make the net look right.” Correct it or mark it void and leave it.

If you also send quotes and invoices, keep those in their own log. Mixing a proposal into the expense sheet double-counts hope as money. A separate quote log is a different job: what you offered, what you won, what you still need to follow up.

What to tell yourself before you buy any template

You still have to keep receipts the way your preparer expects. You still have to know your entity and your state. A formula will not choose a retirement plan, a home-office ratio, or whether a meal was with a client. If a label in the file matches a Schedule C line, that is a convenience for sorting, not a determination.

The LLC expense workbook for 2027 is that sorting file: expenses in editable categories lined up with common Schedule C Part II descriptions, a monthly summary by category, income, net, and a chart. Formulas only, no macros. It opens in Excel and Google Sheets. It is a general organizational tool. The line mapping is a guide and may change. It does not constitute tax advice.
