Tax Compliance Questionnaire Template for Accountants

A tax compliance questionnaire is the annual form you send clients to check whether their tax obligations are current and to catch compliance gaps before they turn into penalties. It covers filing requirements, payment status, entity changes, and regulatory updates that affect their returns.

Unlike a tax organizer (which collects income and deduction data for return preparation), a compliance questionnaire asks whether the client is meeting their obligations -- all returns filed, all payments made, all elections current, all entities in good standing.

Here's the complete questionnaire template organized by compliance area, plus tips for building it into your annual workflow.

Section 1: Filing Compliance

• Are all federal income tax returns filed and current? (If no, which years are outstanding?)
• Are all state income tax returns filed and current? (List states where you have filing obligations)
• Are all payroll tax returns filed and current? (Federal 941/940, state withholding, state unemployment)
• Are all sales tax returns filed and current? (List states where you collect sales tax)
• Are all information returns filed? (1099-NEC, 1099-MISC, 1099-INT, 1099-DIV, 1095 series)
• Have all W-2s and W-3s been filed for the prior year?
• Are you required to file any foreign reporting forms? (FBAR, Form 5471, Form 8865, Form 8858)
• Are all Beneficial Ownership Information (BOI) reports filed with FinCEN?

Section 2: Payment Compliance

• Are all estimated tax payments current? (Federal and state -- list amounts and dates paid for each quarter)
• Do you owe any back taxes to the IRS or any state? (If yes, what year(s) and approximate amount?)
• Are you on an IRS installment agreement or payment plan? (If yes, provide details and current balance)
• Are all payroll tax deposits current? (Federal and state)
• Are all sales tax payments current?
• Have you received any penalty or interest notices? (Upload copies)

Section 3: Entity and Registration Compliance

• Has your entity type changed since last year? (Conversion, new entity, dissolution)
• Have you registered to do business in any new states?
• Is your state annual report/franchise tax filing current?
• Are all business licenses and permits current?
• Has your registered agent information changed?
• Have there been any ownership changes? (New partners, shareholders, or members? Departures?)
• Have you formed or dissolved any subsidiaries or related entities?

Section 4: Nexus and Multi-State Compliance

• Do you have employees or contractors working in states where you don't currently file?
• Have you exceeded economic nexus thresholds in any new states? (For sales tax or income tax purposes)
• Do you have physical presence (office, warehouse, inventory) in any states where you don't file?
• Have you started selling products or services into new states?
• Are you registered for sales tax in all required states?

Section 5: Employment Compliance

• Have you added any new employees this year?
• Have you hired any independent contractors? (Are they properly classified?)
• Have there been any changes to employee benefits? (Health insurance, retirement plans)
• Are all I-9 forms current for all employees?
• Are you compliant with state-specific employment requirements? (Paid leave, minimum wage, workers' comp)
• Have you received any Department of Labor or state labor board inquiries?

Section 6: Regulatory Changes and Elections

• Are you aware of any tax law changes that affect your business for the current year?
• Do any tax elections need to be made or renewed? (S-Corp election, accounting method change, depreciation methods)
• Are retirement plan documents current and in compliance? (Has the plan been restated or amended as required?)
• Are you subject to any new industry-specific regulations?
• Do you need to update your record retention policy?

When to Send the Compliance Questionnaire

Send the compliance questionnaire at one of these trigger points:

• Annually in Q4 (October-November): Before year-end planning discussions. This gives you time to fix compliance gaps before the calendar year closes.
• At engagement renewal: When you issue the annual engagement letter, include the compliance questionnaire as part of the renewal process.
• After a major business change: If the client acquires a company, enters a new state, or changes entity type, send a targeted compliance review.

How to Use the Results

Create a compliance action plan

For each "no" or "unsure" answer, document the issue, the risk, the deadline, and the required action. Present this to the client as a prioritized list -- penalties and interest don't wait.

Feed results into tax planning

Compliance gaps often reveal planning opportunities. A client who discovers nexus in three new states may benefit from a cost segregation study or entity restructuring. Use the questionnaire results to shape your year-end planning recommendations.

Keep a paper trail

File the completed questionnaire. If the client later claims "you never told me I needed to file in California," the questionnaire showing they answered "yes" to having employees there is your documentation.

Frequently Asked Questions

What is a tax compliance questionnaire?

An annual questionnaire that accountants send clients to verify all tax obligations are current -- returns filed, payments made, registrations active, and entities in good standing. It catches compliance gaps before they result in penalties or interest.

How is a compliance questionnaire different from a tax organizer?

A tax organizer collects income and deduction data for return preparation. A compliance questionnaire checks whether the client is meeting all filing, payment, and regulatory obligations. The organizer asks "what did you earn?" The compliance questionnaire asks "are all your obligations current?"

When should I send a tax compliance questionnaire?

Annually in Q4 (October-November), before year-end planning. This gives you time to close gaps before the calendar year ends. Also send one when a client makes major business changes -- acquisitions, new states, entity restructuring.

What are the most common compliance gaps for small businesses?

Multi-state nexus (selling into states without filing), estimated tax payment shortfalls, unfiled information returns (1099s), expired business registrations, and worker misclassification (treating employees as contractors). The compliance questionnaire surfaces these before they become penalties.

Should I charge separately for the compliance review?

Many firms include the annual compliance questionnaire as part of their engagement. If the review uncovers major work (filing back returns, resolving notices, multi-state registrations), scope that separately with its own fee and timeline. The questionnaire itself is a value-add; the remediation work is billable.
