How do I organize work expenses when I’m self-employed in the US?
The short answer
Pick one place for your expense records, note each purchase while you remember it, and keep the supporting document. Separate personal spending from work spending. Once a week, check dates, amounts and duplicates. A notebook or spreadsheet is enough to start; the aim is to find and understand each record later.
What should I write down when I buy something for work?
Think about the question you will ask six months from now: what did I buy, and what was it for? A note that only says “store, $65” makes you reconstruct the story.
- The purchase date and amount paid.
- The store or supplier and what you bought.
- The work it was used for, without unnecessary private details about your customer.
- How you paid and where you saved the receipt.
- A “needs review” mark if something is missing.
This is a practical organization method, not a guarantee that a purchase is deductible.
What does a useful expense record look like?
Illustrative example: on September 28 you bought $65 of cleaning supplies for two jobs that week. You paid by card and saved a photo named “09-28-cleaning-65”. Your note could read:
09/28 — $65 — cleaning supplies for this week’s jobs — card — receipt: 09-28-cleaning-65.
If the same purchase included items for your home, separate those line items. If you cannot work out the split, flag it for review instead of treating the entire purchase as a work expense.
What about cash, Zelle and mixed spending?
Keep a list of payments received and a separate list of expenses. If you received $300 for a job and moved that same $300 between your accounts, do not count the transfer as another job payment. Flag the movement so you can check it.
The payment method helps you find a transaction, but it does not tell its whole story. A bank entry may need a receipt, invoice or additional context. Keep those documents with your records. The IRS explains what supporting documents can show.
A weekly review you can actually repeat
- Bring the week’s purchases into the place you chose.
- Compare them with available receipts and account activity.
- Look for repeated amounts, refunds or personal items mixed in.
- Add the work purpose while you still remember it.
- Keep unresolved questions marked for your accountant.
Start with three recent purchases today. You do not have to finish the entire year before building a habit you can maintain.
Do I need an app or accounting skills?
A notebook or spreadsheet can work if you keep it current. If sitting down to type after work is the problem, try capturing the details when the purchase happens. Choose a tool that fits your routine and lets you review and retrieve your records.
The IRS offers general recordkeeping guidance. Recording a purchase and deciding its tax treatment are different steps.
