Business Tax Projection Preparation: A Quarterly Record Checklist
A projection is only as useful as its inputs. Prepare current books, payments and expected transactions so the advisor can distinguish a change in the business from missing or stale information.
Set a common reporting date
Use financial statements through the same cutoff date for every entity. Identify unreconciled accounts, unusual income and expenses awaiting classification. Tell the reviewer whether the business reports on a cash or accrual basis and whether the statements are final or provisional.
Assemble household and entity inputs
Bring income information outside the operating business, payroll, withholding and estimated payments. Identify the owner, entity, jurisdiction, amount and payment date for each tax payment. Bank proof is useful when a payment is missing from an online account or the prior preparer file.
Separate recurring and one-time activity
Prepare an ordinary operating forecast and a separate list of planned equipment purchases, property transactions, distributions, hiring changes and exits. Record the expected date and certainty of each event. A possible transaction should be marked as a scenario rather than embedded in the baseline.
Create an action register
For each recommendation, ask for the decision deadline, implementation owner, required records and follow-up date. Reconcile the next projection against the prior assumptions to understand what changed.
Printable preparation worksheet
Use a private working copy to record the document location, outstanding question and person responsible for completing each item. These blank fields do not submit or store information online. Keep sensitive data in your secure records.

|---|---|---|
| Financial statements and reconciliation date | ________________ | ________________ |
| Withholding and estimated-payment proof | ________________ | ________________ |
| Household income outside the business | ________________ | ________________ |
| Planned transactions and dates | ________________ | ________________ |
| Open accounting questions | ________________ | ________________ |
Before you request advice
Mark unresolved items clearly and explain any deadline that may affect the review. Ask for an individualized conclusion and a written work scope before relying on a recommendation. A completed preparation worksheet is evidence organization, not approval of a tax position.
