Being ready for a tax review means you can explain the records behind a return. It does not mean an audit is impossible or that every recorded purchase is deductible. This checklist gives a startup a practical way to prepare that evidence throughout the year.
1. Confirm the entities and periods
List each legal entity, accounting system and reporting period. Keep formation and tax-election information available to the preparer. When one founder handles several businesses, do not assume a shared inbox or payment card identifies which entity incurred every cost.
2. Assign the collection routes
Identify where supplier invoices, software receipts, travel records and employee submissions arrive. Give each source an owner and establish a route for missing documents. Include records held in supplier portals or payment platforms so they are not overlooked by an email-only process.
Receiptor AI's automatic extraction collects emailed receipts and invoices. WhatsApp and iMessage provide additional submission routes, while historical extraction helps with older messages.
3. Preserve source documents and context
Keep originals with the extracted details and note the business purpose where it is not obvious. The IRS guidance on supporting records covers records used to substantiate business activity. There is no universal rule that everything below $75 can be ignored.
Make a separate list of documents that remain missing, who will request them and what alternative evidence is available for professional review.
4. Review related documents and duplicates
An invoice, payment receipt and forwarded copy may describe the same purchase. Receiptor supports transaction groups and duplicate handling to help organize the evidence. Mathematical validation and AI review can surface discrepancies; a reviewer still needs to resolve unclear amounts, entities or accounting treatment.
Test the process with a purchase paid in two installments and a refunded purchase. Confirm that the resulting records explain the sequence rather than simply adding all document totals together.
5. Reconcile and investigate exceptions
Reconcile the books with bank, card, payroll and other relevant source records. Assign someone to investigate unexplained differences, transfers and missing transactions. Keep an exception list instead of hiding unresolved items in an adjustment account with no explanation.
Receiptor's Xero and QuickBooks integrations connect purchase evidence to appropriate accounting records. Check the attachments and entity after export, not only the sync status.
6. Confirm filing and payment responsibilities
Ask the preparer which returns, jurisdictions and periods are covered. Maintain separate due dates for filing and payment, and keep the instructions used to establish each date. Leave time for the preparer's questions before the official deadline.
After submission, save acceptance confirmations, payment confirmations and any follow-up requests. A sent email to the accountant is not evidence that a return was accepted.
7. Test retrieval and retention
Select a few transactions from the final reports and retrieve their supporting documents. Someone unfamiliar with the original purchase should be able to follow the trail. Use the IRS retention guidance and professional advice to set an appropriate policy, including applicable exceptions and other obligations.
Repeat the checklist at each close. The goal is a record set that can be reviewed and explained, with automation handling collection and people resolving the decisions that require judgment.
