What to Send Your Tax Preparer: A Small-Business Year-End Checklist

Organize your business records before tax preparation begins, with a clear document checklist and a practical handoff plan for your preparer or existing CPA.

Two professionals organizing folders during a business records review.

Send your tax preparer a complete, organized picture of the business: financial records for the correct year, supporting documents, relevant prior returns and a clear list of anything unresolved. Ask for the preparer’s own checklist first, because the exact requirements depend on your business and the return being prepared.

This small business tax preparation checklist focuses on the handoff. You can begin organizing the folders before year-end, then add final statements and year-end documents as they become available.

Start with four questions for your preparer

Before uploading a large collection of files, agree on what the person receiving them actually needs:

  1. Which business, tax year and returns are included in this engagement?
  2. Which reports and supporting records should I provide?
  3. How should I send sensitive documents securely?
  4. When do you need the complete package, and what should I do if something is missing?

Also mention changes in ownership, business activity or where you operate. Do not assume last year’s document request covers a changed business. A short conversation at the start can prevent repeated requests later.

The following is an organizing framework, not a statement that every item applies to every business.

Keep the supporting records connected to the books

The IRS explains that records should show business income and expenses, and that supporting documents help substantiate entries. Its business recordkeeping guidance identifies documents such as receipts, invoices and records for business assets. The precise evidence needed depends on the transaction.

A report is easier to review when someone can find the underlying document. You do not need an elaborate filing system. Consistent names and a folder structure everyone understands are more useful than dozens of unexplained attachments.

Use one missing-information list

Instead of delaying the entire conversation while you search for one statement, list what is unavailable. Include the item, period, person requesting it and expected next step. Your preparer can then tell you whether it prevents work from starting or affects the filing plan.

Do not replace a missing record with a guessed number. If a document cannot be recovered, explain the situation and ask what other evidence the preparer can evaluate.

Tell your preparer what the reports do not explain

Numbers rarely tell the whole operational story. Add a short note about unusual events: an equipment purchase, a new account, business costs paid personally, a financing change, a sale of business property or a switch in bookkeeping systems.

Label these as questions or facts to review. Buying equipment, for example, does not by itself establish the deduction or timing that applies. Your role in the handoff is to provide the details; the relevant professional determines the treatment.

Check for unfinished bookkeeping

Ask whoever maintains the books which accounts and periods are complete. “The software is connected” is not the same as confirmation that the records have been reviewed. If cleanup is needed, agree on whether your bookkeeper or preparer will do it and whether it changes the scope or timing.

Keep your existing CPA and improve the handoff

You do not have to change tax professionals to get bookkeeping help. Easyfin can organize the books and coordinate the year-end package with your existing CPA. Easyfin also offers business tax preparation and filing when the return fits the agreed service scope.

Review Easyfin’s tax preparation and CPA collaboration services to see how the two arrangements work.

For a smooth handoff, identify one contact at each business. Agree on who answers bookkeeping questions, who requests additional information and who confirms that the requested package has been received. Avoid having several people make unrelated changes to the same records without coordination.

A suggested sequence for getting ready

  • Before year-end: confirm the engagement, request the document list and locate records that are already available.
  • As final documents arrive: save them to the agreed location and update your missing-item list.
  • Before sending the package: check the business name, reporting year, completeness and agreed report versions.
  • After handoff: answer follow-up questions and separately confirm the preparation, approval and filing steps with your preparer.

These are organizational stages, not tax deadlines. Your preparer should confirm the dates and responsibilities that apply to your particular returns.

Questions owners ask before tax season

Are bank statements enough?

They may be part of the evidence, but they may not explain the business purpose or full nature of a transaction. Keep the associated invoices, receipts and other support your preparer requests.

Should I email my complete tax records?

Ask your preparer for the approved secure transfer method. Schedule a free call using Easyfin’s booking popup to discuss the help you need. Agree on a secure document handoff before sending sensitive financial or identity information.

What if I am behind?

Reach out with the last completed period and an honest description of what is missing. A defined recovery plan is more useful than waiting until every folder looks perfect.
