I didn’t track my expenses all year. Where do I start?

The short answer

Start with one month, not the whole year. Gather available statements, receipts and invoices, then list the transactions and mark what you can support and what is missing. Request copies where possible. Take open questions to your accountant instead of turning memories or averages into confirmed expenses.

First, gather what you still have

Create a folder for the year and another for the month you are reviewing. Search email receipts, store purchase histories, invoices and activity from accounts you used. A work calendar may help you remember context, but it does not automatically replace supporting documents.

Start with a familiar week: a painting job, several houses you cleaned, or your salon chair rent. Finishing a small period gives you a process to repeat without mixing everything together.

Separate what you found from what is missing

Use three labels: “document found”, “information missing” and “ask accountant”. Record the source next to each transaction. These labels describe your progress; they do not decide whether the documentation is sufficient for taxes.

Illustrative example: you find an $89 hardware-store charge and remember buying a drill. Without the item details, write “$89 charge, item to confirm” and request a copy from the store. Do not turn the memory into an invoice.

What if I lost a receipt?

Ask the supplier for a copy and search for a purchase confirmation. Keep the documents you have and explain what is missing. The IRS describes reconstructing records with a tax preparer’s help; this does not mean every estimate works for every expense.

Do not make up dates, amounts or receipts. If you only remember “about $40 every week”, take that question to the professional. They need to assess what can be reconstructed and how to support it in your situation.

Avoid counting the same purchase twice

  • A card purchase may appear on both a receipt and a statement: link those documents to one transaction.
  • Paying that card’s bill is not another purchase of supplies.
  • Identify a refund alongside the original purchase.
  • A transfer between your own accounts needs context before you classify it.

Compare dates, amounts and suppliers. Two equal charges can also be separate purchases: check before deleting anything.

What to do today and what to leave for review

  1. Choose the latest complete month you have.
  2. Organize ten transactions and link their supporting documents.
  3. Keep a separate list of unanswered questions.
  4. Agree with your accountant on how to proceed.
  5. Start recording new purchases today.

A tool can help you record new expenses. It cannot recover receipts it does not have or automatically verify months of past spending.
