Tax time starts
with books
you can explain.
Before your tax preparer can work through the return, they need organized records and a clear view of what is complete. Use this checklist to gather the books, supporting documents and questions for that handoff.
For US business record preparation. Confirm your preparer’s requirements for the relevant tax year.
Gather. Check.
Flag the gaps.
A small-business tax checklist is a list of records and questions to organize before return preparation. It should help you identify missing periods, separate reports from supporting documents and agree who resolves each open item.
This guide focuses on bookkeeping preparation. It does not determine your tax liability, eligibility for a deduction or filing requirements. Those decisions belong with your tax professional.
The IRS recordkeeping overview explains why records support financial statements and tax returns; the records needed vary with the business.
0 of 16 items checked. This checklist is not saved or submitted.
Agree what the handoff covers.
Reference: IRS Publication 583: Starting a Business and Keeping Records.
Tell your preparer which entities and reporting period the records cover. Entity name alone does not settle the required tax forms or tax treatment; ask your preparer to confirm those.
Include business bank accounts, cards, payment processors and accounts opened or closed during the year. Flag business transactions paid through personal accounts for separate review.
Collect prior-period reports and relevant opening-balance information. Ask the preparer or prior accountant which prior returns and schedules they need.
Agree when records are needed and how to transfer them with your tax preparer. Use their agreed process for sensitive identifiers and documents, not a public enquiry form.
Make the money movements explainable.
Reference: IRS: What to do with Form 1099-K.
Check for missing months or pages. Gather bank, card and processor records across the entire agreed period rather than relying on a year-end balance screenshot.
Bring together sales invoices, point-of-sale or store summaries, cash-sale records and relevant information forms. Flag cancelled invoices, refunds and differences between systems.
Keep processor summaries alongside payout records. Form 1099-K gross amounts are not adjusted for items such as fees and refunds, so compare the form with your underlying records. Ask the preparer about discrepancies.
Label movement between your own accounts, loan proceeds and owner funding rather than treating every deposit as a sale. Your bookkeeper and preparer need the context to determine the right recording and tax treatment.
A category total needs context.
Reference: IRS: What kind of records should I keep?.
Keep records showing the payee, date, amount and description or business purpose where relevant. One document may not substantiate every part of an expense; a statement line can leave questions unanswered.
List these separately with available support. Recording an expense in the books does not, by itself, make the full amount deductible. Ask your tax preparer to review the treatment.
Include purchase dates, amounts, supporting invoices and information about disposals. Bring prior asset schedules where available. Your preparer determines depreciation and applicable tax treatment.
Use existing payroll-provider reports and contractor payment summaries if applicable. Inventory businesses should discuss purchases, year-end quantities and supporting records with their preparer. Ask which additional forms or schedules are required.
Send the reports and the open questions.
Reference: IRS: Recordkeeping.
Prepare the profit and loss statement, balance sheet and other reports requested by your preparer, using the agreed reporting basis and period. Ensure you know which version is being handed over.
Check the included accounts against their statements. Flag missing statements, unresolved differences and incomplete months. A report that prints without an error message is not proof the books are reconciled.
Ask about unusual customer or supplier balances, loans, owner balances and timing items. Which adjustments belong in the books depends on the accounting basis and agreed scope.
For each open question, state the period, amount if known, description, available evidence and person responsible for the next step. Your preparer should know what remains uncertain before relying on the reports.
Bookkeeping work.
Tax-preparer decisions.
Set responsibilities before sending the package. Do not assume that a bookkeeping engagement includes return filing, or that your preparer has agreed to reconstruct incomplete books.
| Work | Bookkeeping preparation | Tax-preparer discussion |
|---|---|---|
| Missing months | Record and reconcile the agreed historical periods. | Confirm when the records are needed and what gaps mean for filing. |
| Recorded errors | Assess and correct the agreed bookkeeping issues. | Evaluate any effect on a return or prior tax treatment. |
| Expense and asset records | Organize entries and supporting information. | Determine tax treatment, eligibility and required evidence. |
| Final handoff | Supply the agreed reports and open-items list. | Confirm forms, adjustments and return-preparation scope. |
A short handoff note can prevent guessing
Illustrative note: “The reports cover January–December for one entity. February’s card statement is missing. A customer deposit and an asset purchase still need review. Please confirm which additional schedules you require.”
A note like this makes uncertainty visible. It is not a substitute for completing the work, a customer example or proof that a return can be filed.

Tell us which bookkeeping records need attentionQuestions before
you get started.
What documents are needed for small-business taxes?
The list depends on your business, tax classification, reporting period and circumstances. Start with complete account statements, income records, expense support, relevant asset and payroll or contractor records, and the reports requested by your tax preparer. Confirm their own checklist before handoff.
Are bank statements enough for business taxes?
They show movements, but a line on a statement may not explain the business purpose or all elements of an expense. The IRS says supporting documents can include bills, invoices, receipts and payment evidence, and that a combination may be needed. Keep the available supporting records and discuss gaps with your preparer.
Should I send a profit and loss statement or every receipt?
Ask your preparer how they want the package organized. Agreed reports summarize the books; supporting records explain the entries. A report and an unorganized pile of receipts serve different purposes. Keep both available and label any unresolved questions.
What should I do if months of bookkeeping are missing?
Map the missing periods and accounts first. Catch-up bookkeeping can be assessed to record the historical activity before the handoff. Tell both the bookkeeper and preparer about deadlines; the bookkeeping project and return filing remain separate responsibilities.
What if the reports contain duplicates or unexplained balances?
Flag those issues before handing over a version you expect the preparer to rely on. Bookkeeping cleanup assesses recorded errors and their effects. If a prior return used the affected records, your tax professional needs to advise on the implications.
How long should I keep business tax records?
There is no single retention period for every record and circumstance. The IRS explains that the period depends on what the document records and provides different rules and exceptions. Review its record-retention guidance and ask your adviser before disposing of records.
Does completing this checklist mean my tax return is ready to file?
No. The checklist organizes a bookkeeping handoff. Your tax professional still determines applicable forms, deductions, adjustments, elections, due dates and whether the evidence is sufficient for the return.
Can Bookeeping.us file my business taxes?
Tax preparation and filing are not part of the bookkeeping offering described here. We can discuss organizing the books, catch-up work, cleanup and monthly reporting for your business. Arrange the filing engagement separately with your tax professional.
