How to Classify a Worker: A Review Workflow for Firms

Classify a worker by reviewing the full working relationship under every law that applies. For federal employment tax, the IRS groups evidence into behavioral control, financial control, and type of relationship, and directs businesses to weigh the entire relationship and document each factor used (https://www.irs.gov/businesses/small-businesses-self-employed/independent-contractor-self-employed-or-employee). For federal wage and hour law, the Department of Labor separately applies an economic reality analysis under the FLSA (https://www.dol.gov/agencies/whd/fact-sheets/13-flsa-employment-relationship). A contract, form, title, or preferred label cannot decide status by itself. Route specific decisions and close calls to qualified professionals.

This page explains the rules for firm review workflows. It is not tax or legal advice.

Who this page is for

This workflow is written for accounting and bookkeeping firms that prepare worker files for client decision-makers and qualified advisers. It covers how to define the review question, collect source records, organize evidence, document unresolved facts, and prepare a defensible handoff.

The federal framework comparison belongs in our independent contractor vs employee guide. The operational differences between contractor and employee records belong in 1099 vs W-2. Specific classification decisions require a qualified professional who can consider the complete facts and every applicable jurisdiction.

Keep the review questions separate

The IRS common-law framework addresses worker status for federal employment tax purposes. The IRS groups evidence into behavioral control, financial control, and type of relationship. Businesses must consider the entire relationship, weigh conflicting facts, and document each factor used in the determination (https://www.irs.gov/businesses/small-businesses-self-employed/independent-contractor-self-employed-or-employee).

The DOL framework addresses employee status under the FLSA. Its economic reality analysis asks whether the worker is economically dependent on a potential employer for work or is operating an independent business (https://www.dol.gov/agencies/whd/fact-sheets/13-flsa-employment-relationship).

As of July 20, 2026, the DOL posture has three parts. The 2024 six-factor rule remains in effect for private litigation. The Wage and Hour Division no longer applies that rule in its investigations under Field Assistance Bulletin 2025-1. DOL announced a proposed replacement rule on February 26, 2026, and the proposal was published on February 27, 2026 at 91 FR 9932 (https://www.dol.gov/agencies/whd/fact-sheets/13-flsa-employment-relationship, https://www.dol.gov/sites/dolgov/files/WHD/fab/fab2025-1.pdf, https://www.federalregister.gov/documents/2026/02/27/2026-03962/employee-or-independent-contractor-status-under-the-fair-labor-standards-act-family-and-medical).

The proposal would use five non-exhaustive factors. It identifies two core factors: the nature and degree of the worker’s control over the work, and the worker’s opportunity for profit or loss based on initiative or investment. Three other identified factors address skill, permanence, and whether the work forms part of an integrated unit of production. Additional factors may also be considered. The proposal gives greater weight to the parties’ actual practices than to contractual or theoretical possibilities (https://www.dol.gov/agencies/whd/flsa/misclassification/2026rulemaking).

The 60-day comment period closed April 28, 2026. The current DOL rulemaking page still presents the action as a proposed rule and does not identify a final rule as of July 20, 2026 (https://www.dol.gov/agencies/whd/flsa/misclassification/2026rulemaking). Recheck the current DOL sources whenever a specific wage and hour question is reviewed.

Other federal, state, and local laws can use different classification standards. Define the applicable questions and jurisdictions before gathering evidence (https://www.dol.gov/agencies/whd/flsa/misclassification/2026rulemaking/faqs).

The review workflow

Step 1: Define the scope and decision owner.

Open one review record per worker or worker class. Record the client, role, review date, applicable jurisdictions, and each legal question under review. Identify the client decision-maker and the qualified adviser responsible for applying the relevant standards.

Keep federal employment tax, FLSA, and other legal questions in separate sections because the governing standards and purposes can differ (https://www.irs.gov/businesses/small-businesses-self-employed/independent-contractor-self-employed-or-employee, https://www.dol.gov/agencies/whd/flsa/misclassification/2026rulemaking/faqs).

Step 2: Build a source index.

Gather the agreement or statement of work, role description, invoices and payment records, onboarding records, benefits records, scheduling and supervision records, training materials, evaluation methods, tool and equipment records, expense treatment, relationship history, and evidence of activity in the wider market.

Record the source and date for each item. These records correspond to evidence the IRS identifies under behavioral control, financial control, and type of relationship (https://www.irs.gov/businesses/small-businesses-self-employed/behavioral-control, https://www.irs.gov/businesses/small-businesses-self-employed/financial-control, https://www.irs.gov/businesses/small-businesses-self-employed/type-of-relationship).

Step 3: Build the IRS evidence map.

Organize the facts under the three IRS categories:

Behavioral control: Instructions, training, evaluation methods, supervision, and the right to direct how the work is performed (https://www.irs.gov/businesses/small-businesses-self-employed/behavioral-control).
Financial control: Investment, unreimbursed expenses, opportunity for profit or loss, market availability, tools and supplies, and method of payment (https://www.irs.gov/businesses/small-businesses-self-employed/financial-control).
Type of relationship: Written agreements, employee-type benefits, expected permanency, and whether the services are a key activity of the business (https://www.irs.gov/businesses/small-businesses-self-employed/type-of-relationship).

Record the facts supporting each direction and any conflicting evidence. Do not assign a point score. The IRS says there is no set number of factors, the relevance of a factor can vary by situation, and no single factor stands alone (https://www.irs.gov/businesses/small-businesses-self-employed/independent-contractor-self-employed-or-employee).

Step 4: Run the DOL review separately.

Create a separate section for the FLSA analysis. Record the official sources, review date, and purpose of the analysis.

The qualified reviewer should identify whether the question concerns WHD investigative posture, private litigation, or another legal context. The current DOL posture differs across those contexts, and the proposed replacement rule has not become final as of July 20, 2026 (https://www.dol.gov/agencies/whd/fact-sheets/13-flsa-employment-relationship, https://www.dol.gov/sites/dolgov/files/WHD/fab/fab2025-1.pdf, https://www.dol.gov/agencies/whd/flsa/misclassification/2026rulemaking).

Step 5: Mark gaps and conflicts as unresolved.

List every missing or inconsistent fact, the source needed to resolve it, and the person responsible for obtaining it.

Keep both the written terms and the actual working practices in the file. The IRS directs businesses to assess the complete relationship. The pending DOL proposal similarly gives actual practice greater relevance than contractual or theoretical possibilities (https://www.irs.gov/businesses/small-businesses-self-employed/independent-contractor-self-employed-or-employee, https://www.dol.gov/agencies/whd/flsa/misclassification/2026rulemaking).

Step 6: Prepare the review memo.

The dated memo or worksheet should identify:

the question reviewed
applicable laws and jurisdictions
the source index
evidence organized by framework
unresolved facts
the qualified reviewer’s conclusion
the reviewer and decision date
the implementation owner
the trigger for a future review

The IRS specifically directs businesses to document each factor used in reaching the determination (https://www.irs.gov/businesses/small-businesses-self-employed/independent-contractor-self-employed-or-employee).

Step 7: Escalate close calls.

Either the business or the worker may file Form SS-8 to request an IRS determination of worker status for federal employment taxes and income tax withholding. The IRS reviews the facts and circumstances and states that a determination may take at least six months (https://www.irs.gov/forms-pubs/about-form-ss-8, https://www.irs.gov/businesses/small-businesses-self-employed/independent-contractor-self-employed-or-employee).

Form SS-8 addresses the federal employment-tax question. Other legal frameworks may still require separate review.

Worker classification review checklist

Review stage	Suggested record	Handoff condition
Scope	Legal questions, jurisdictions, client decision-maker, qualified adviser, review date	Each question has a named owner

IRS evidence map	Facts under behavioral control, financial control, and type of relationship	Conflicts are visible and no point score is used
DOL review	Official sources, review date, and purpose of the analysis	Current enforcement and rulemaking posture is confirmed
Review memo	Sources, facts, unresolved items, qualified reviewer's conclusion, and decision date	The conclusion and its basis are recorded
Workflow handoff	Payroll or contractor-documentation destination and implementation owner	Classification stays with the client and qualified advisers

Route the record after the decision

Employee records move into the Form W-4 and payroll workflow. The IRS describes Form W-4 as the certificate employees complete so an employer can withhold the correct federal income tax from their pay (https://www.irs.gov/forms-pubs/about-form-w-4).

Independent contractor records move into the Form W-9 collection workflow. The IRS describes Form W-9 as the form used to provide a correct taxpayer identification number for information-return reporting (https://www.irs.gov/forms-pubs/about-form-w-9).

The later information-return determination is a separate review covered in who gets a 1099. The W-9 vs W-4 guide covers the form handoff for each relationship.

Prepare contractor records for the next handoff

After a qualified classification decision routes a record to the contractor workflow, W9Finder helps accounting and bookkeeping firms organize vendor lists, flag missing W-9s and incomplete records, send secure request links, track reminders, manage review handoffs, and export reviewed CSV files for the firm’s filing process. Classification remains with the business and its qualified advisers. Explore W9Finder

FAQ

Does a signed independent contractor agreement settle a worker's status?

A signed agreement is one item within the relationship evidence. The IRS directs businesses to evaluate the complete relationship and says no single factor stands alone (https://www.irs.gov/businesses/small-businesses-self-employed/type-of-relationship, https://www.irs.gov/businesses/small-businesses-self-employed/independent-contractor-self-employed-or-employee). Under the FLSA analysis, the working relationship's economic reality controls over a label or agreement (https://www.dol.gov/agencies/whd/fact-sheets/13-flsa-employment-relationship).

Can a worker-classification checklist use a point score?

A point score conflicts with the IRS framework. The IRS says there is no fixed number of factors that determines status, no single factor controls, and the relevance of individual facts can vary by situation (https://www.irs.gov/businesses/small-businesses-self-employed/independent-contractor-self-employed-or-employee).

What is Form SS-8 and who can file it?

Form SS-8 asks the IRS to determine worker status for federal employment taxes and income tax withholding. Either the business or the worker may file it. The IRS states that a determination may take at least six months (https://www.irs.gov/forms-pubs/about-form-ss-8, https://www.irs.gov/businesses/small-businesses-self-employed/independent-contractor-self-employed-or-employee).

Do the IRS and the Department of Labor use the same classification test?

The IRS applies common-law categories for federal employment-tax purposes. DOL applies an economic reality analysis for the FLSA and related statutes within its authority. Other federal, state, and local laws may apply additional standards (https://www.irs.gov/businesses/small-businesses-self-employed/independent-contractor-self-employed-or-employee, https://www.dol.gov/agencies/whd/fact-sheets/13-flsa-employment-relationship, https://www.dol.gov/agencies/whd/flsa/misclassification/2026rulemaking/faqs).
