# Prepare a reconciliation packet

First complete the record using this book’s fictional case, marking each field as known, assumed or unresolved. Explain one conclusion using the supporting amounts or documents. Then compare your reasoning with the discussion below. For personal use, keep private financial details in secure records; this worksheet needs no account numbers or credentials.

| Record field | Your observation |
|---|---|
| Tax year and account scope |  |
| Original and corrected statements |  |
| Lot identifiers and adjusted basis |  |
| Proceeds and transaction costs |  |
| Acquisition / disposition dates |  |
| Replacement purchases across accounts |  |
| Option close / expiry / exercise events |  |
| Digital-asset transfers versus disposals |  |
| Special regimes and election evidence |  |
| Withholding, estimates and carryovers |  |

### Questions worth checking

The same stock sale appears in two imported files. A doubled $780 gain is a data problem, not a new tax rule. Match transaction identifiers and reconcile to the independent statement before calculating the return.

A December loss is followed by a January purchase. Do not finalize the wash-sale analysis at December 31 simply because the calendar year ended. The relevant window can extend into the next year and across accounts.

For the purchased call, closing, expiry and exercise are alternative paths. Never add the $201 expiry loss to the $5,201 stock basis from exercise as though both occurred. Identify the actual event and preserve its confirmation. The worksheet organizes facts; it does not establish eligibility for a tax election or validate a return.
