Subcontracting in Cleaning: How to Use Subs Without Triggering Misclassification Audits

Subcontracting is the fastest way to scale a cleaning business without adding payroll — and the fastest way to trigger a DOL audit if you do it wrong. The distinction between an independent contractor and an employee is not one you get to make unilaterally; the IRS, the Department of Labor, and most state labor agencies each have their own test, and misclassification under any of them results in back payroll taxes, penalties, and potential workers comp liability.

Used correctly, subcontractors let a small cleaning operation accept overflow work, test new service lines, and cover geographic areas without hiring. This article covers the legal framework, the contract structure, the margin math, and the certificate of insurance requirements that separate operators who scale with subs from those who get audited.

The IRS Common Law Test: What Makes Someone an Employee

The IRS uses a 20-factor behavioral control test (summarized into three categories in Revenue Ruling 87-41) to determine whether a worker is an employee or a contractor. For cleaning businesses, the factors that most often trigger misclassification findings:

Behavioral control (most dangerous for cleaning businesses):

• You set the specific days and hours the worker must clean — that's employment
• You require the worker to follow your specific cleaning procedures or use your equipment — that's employment
• You provide training on how to perform the cleaning — that's employment

Financial control:

• The worker cleans only for you and has no other clients — courts weigh this heavily as employment evidence
• You pay by the hour rather than by the job — hourly payment is an employment indicator
• You provide all supplies, chemicals, and equipment — equipment provision is an employment indicator

Relationship factors:

• The arrangement is indefinite and ongoing, not project-specific — indefinite duration weighs toward employment
• The work is central to your business (cleaning accounts) rather than a peripheral specialty

The practical implication: a sub who cleans your accounts on your schedule, using your equipment, every week, indefinitely, looks like an employee to the IRS regardless of what the contract says. The contract does not override economic reality.

State Tests: ABC Test vs. IRS Test

Sixteen states (including California, Massachusetts, New Jersey, Illinois, and Connecticut) use the ABC Test, which is significantly harder to pass than the IRS test. Under the ABC Test, a worker is an employee unless all three of the following are true:

A. The worker is free from the control and direction of the hiring entity
B. The work performed is outside the usual course of the company's business
C. The worker is customarily engaged in an independently established trade, occupation, or business

Prong B is the critical one for cleaning companies: if a cleaning company uses a subcontractor to clean accounts, the subcontractor's work is not "outside the usual course" of the cleaning company's business — it is the business. California courts have consistently ruled that cleaning subs fail Prong B. This is why many California-based cleaning operators either hire employees directly or use a professional employer organization (PEO) rather than subcontract.

Subcontractor Contract Requirements

A verbal arrangement with a 1099 sub is legally dangerous. Every subcontractor relationship must be documented with a written agreement that establishes the economic reality of an independent contractor relationship. Your subcontractor agreement must include:

Core provisions:

• Scope of work: Specific accounts, locations, and services — defined by result, not method
• Pricing: Per-job or per-square-foot rate (not hourly)
• Schedule: Client access window (e.g., "Monday/Wednesday/Friday between 6 PM–10 PM"), not mandated hours
• Equipment and supply responsibility: Sub provides their own tools, chemicals, and PPE
• Other clients clause: Sub acknowledges they may and do work for other clients
• Termination: Either party may terminate with X days notice — do not make it indefinite

Insurance and indemnification:

• Sub must carry their own general liability insurance (minimum $1M per occurrence)
• Sub must provide a certificate of insurance naming your company as additional insured
• Sub indemnifies your company for their own acts and omissions

Non-solicitation (not non-compete):

• Standard in cleaning: sub agrees not to solicit your clients directly for 12–24 months after termination
• Non-solicitation is generally enforceable; non-compete agreements in service businesses have faced increasing court challenges

The agreement itself is not a magic shield — if the actual working relationship looks like employment, the contract language will not protect you. The behavior must match the agreement.

Certificate of Insurance: What You Must Collect

Before a subcontractor services any account, you must have a current certificate of insurance (COI) on file. The COI must show:

1. General liability insurance: Minimum $1M per occurrence / $2M aggregate. Your company must be listed as an additional insured — this means the sub's policy extends coverage to you if their work causes a client claim.
2. Workers compensation: If the sub has employees, they must carry workers comp. If the sub is a sole proprietor with no employees, they may be excluded from their state's workers comp requirements, but some clients will require proof of exemption.
3. Policy expiration date: Get a new COI before each policy renewal. An expired COI means you have no actual additional insured coverage.

COI collection is an administrative discipline. Build a tracking system — a simple spreadsheet logging sub name, policy number, carrier, expiration date, and date you received the current COI — and check it monthly. If a sub's COI lapses, stop sending them work until they renew.

Pricing and Margin Math for Subcontracted Work

The standard subcontracting markup in cleaning ranges from 20% to 40% depending on the service type and account complexity. A 25% markup is the minimum threshold to cover your overhead, insurance, client management time, and profit.

Example calculation:

• Client contract: $2,000/month for commercial office cleaning
• Sub rate to perform the work: $1,500/month
• Your gross margin: $500/month (25%)
• From that $500, you cover: general liability premium portion (~$40), client management time (~$80), vehicle/coordination overhead (~$50), profit: ~$330/month

The risk of subcontracting at too thin a margin is that any client complaint, re-service requirement, or sub no-show comes out of your pocket. Build in a re-service buffer — assume 5–10% of accounts will require a callback or re-clean in any given month.

Specialty services (window cleaning, carpet extraction, post-construction) typically command 35–40% markup because they require licensed, insured specialists and the sourcing and vetting cost is higher.

1099-NEC Filing Obligations

If you pay a subcontractor $600 or more in a calendar year, you are required to file a Form 1099-NEC with the IRS and provide a copy to the sub by January 31 of the following year. Requirements:

• Collect Form W-9 from every sub before the first payment. The W-9 captures the sub's legal name, business name, EIN or SSN, and classification. Without a W-9 on file, you are required to withhold 24% backup withholding from payments.
• File Form 1099-NEC (not the older 1099-MISC) for services. Payments to incorporated S-corps and C-corps are generally exempt, but payments to sole proprietors, single-member LLCs, and partnerships require 1099 filing.
• Penalties for late filing: $50–$280 per form, depending on how late, under IRC § 6721.

Accounting software (QuickBooks, Xero, FreshBooks) can auto-generate 1099s from tracked payments if you correctly categorize contractor payments throughout the year. Set up the contractor payment category before the first check goes out — retroactive reclassification is tedious.

FAQ

Can a cleaning business legally use 1099 subcontractors?
Yes, but the working relationship must satisfy the IRS common law test (and the ABC Test in 16 states). The sub must control how they work, provide their own equipment, have multiple clients, and be paid per job — not hourly. In California and other ABC Test states, cleaning subs who perform the company's core service often fail the test and must be classified as employees.

What insurance must a cleaning subcontractor carry?
At minimum, a cleaning subcontractor must carry general liability insurance ($1M per occurrence) and, if they have employees, workers compensation. Require the sub to name your company as an additional insured on their GL policy and collect a certificate of insurance before they service any account.

What is the standard markup on subcontracted cleaning work?
Standard markup ranges from 20–40%. A 25% minimum is typically needed to cover your overhead, insurance, client management time, and profit margin. Specialty services (window cleaning, carpet extraction, post-construction) command 35–40% because the sourcing and vetting cost is higher.

When must I file a 1099-NEC for a cleaning subcontractor?
You must file a 1099-NEC for any individual or unincorporated business you paid $600 or more in a calendar year for services. File with the IRS and deliver a copy to the sub by January 31. Collect a signed W-9 from every sub before the first payment to avoid backup withholding requirements.

What is the risk if I misclassify an employee as a 1099 subcontractor?
Misclassification liability includes back federal payroll taxes (employee and employer shares of FICA), federal unemployment tax, potential state unemployment and workers comp assessments, plus penalties and interest. The IRS can assess the employer share of FICA going back three years, plus failure-to-deposit penalties of 2–15% of the unpaid tax.
