Example scenario · illustrative, not a real seller
You paid cash for an example lot during the 2026 tax year and later discover there is no receipt. A cash withdrawal proves you obtained cash, not necessarily who sold you which items. Rebuild the evidence trail without manufacturing it.
What you’ll get
- Identify which purchase facts the IRS asks records to support.
- Separate corroborating documents from proof of every detail.
- Keep a dated reconstruction with uncertainties visible.
State the filing context and the limits
This guide concerns recordkeeping for the 2026 tax year, using IRS guidance checked November 8, 2026. It does not publish a deduction rate, reporting threshold or tax-return calculation. It is general information, not individual tax advice or a promise that a reconstructed entry will be accepted.
The IRS says purchase records should identify the payee, amount paid, proof of payment, date incurred and a description showing the purchase. Its guidance notes that a combination of documents may be needed to substantiate all elements.
Preserve what exists before writing what you remember
Retain original messages, invoices, payment records and relevant item photographs in a secure private file. Do not alter an original document to make it agree with memory. A bank withdrawal, calendar entry and item photograph can have different evidentiary roles; none automatically proves every missing fact.
Write a reconstruction note using its actual creation date. State the event date you believe is correct, the items, amount and source of each fact. Mark estimates and uncertainty clearly. Do not turn your own reconstruction into a purported receipt issued by the seller.
Worked example: the $60 withdrawal is incomplete evidence
Suppose a $60 withdrawal preceded a claimed cash purchase, but you also bought lunch and retained some cash. The withdrawal alone cannot establish that all $60 purchased resale stock. Keep the actual known amounts separate rather than assigning the entire withdrawal to inventory.
If you recall a $42 lot price but cannot corroborate it, record the recollection and its uncertainty. This example does not authorize a $42 cost entry or prescribe an allocation method. Ask an appropriate tax professional how to handle the unsupported facts before filing.
Repair the next purchase workflow
Ask for an appropriate record at the transaction when practical. Log the seller/payee, date, amount, items and payment evidence contemporaneously, then connect the stock IDs to that record. Store personal and transaction information securely; this site's checkboxes save only step IDs.
A truthful gap is better than fabricated certainty. The operational goal is a traceable record, not a document that merely looks official.
Worked example · hypothetical, not a real seller
Keep the example in view
| Hypothetical purchase file | What it supports or leaves open |
|---|---|
| $60 cash withdrawal | Cash availability, not the specific purchase alone |
| Contemporaneous item photographs | Item identity; not necessarily payment |
| Reconstructed note dated when written | Your account, clearly labelled; not a seller receipt |

Practical questions
Can I create a seller receipt myself after the fact?
Do not fabricate a third-party receipt or backdate a record. You can write an honestly dated reconstruction that clearly identifies itself and preserves uncertainty, but it does not guarantee substantiation.
Does a cash withdrawal prove the resale purchase?
Not by itself. It shows cash was withdrawn, not necessarily the payee, business purpose, item or actual amount paid. Supporting documents may need to be considered together.
