Contractor Agreement
Ref: 2026-001 • Standard Business Template
Machinist Independent Contractor Agreement
This Agreement is made between the Client and the Machinist (Contractor) to establish a formal independent contractor relationship for the provision of machining services.
1. Services Provided
The Contractor agrees to perform the following machining services: CNC milling/turning, manual machining, programming, and/or inspection as specified in the attached Scope of Work. The Contractor shall ensure all parts meet the specified tolerances and quality standards provided in the blueprints or CAD files.
2. Compensation
The Client shall pay the Contractor based on the following schedule: [Flat Fee per Part / Project Milestone / Hourly Shop Rate]. Payment shall be issued within [Number] days of receiving an invoice and a signed inspection report for the completed units. No taxes shall be withheld from this compensation.
3. Independent Contractor Status
The parties agree that the Contractor is an independent contractor and not an employee of the Client. The Contractor retains the 'Right to Control' the sequence, logic, and technical methods used to achieve the desired machining results. The Contractor is responsible for their own work schedule and is free to provide services to other clients simultaneously.
4. Taxes and Benefits
The Contractor acknowledges they are solely responsible for all self-employment taxes, including Social Security and Medicare (FICA), as well as state and federal income taxes. The Contractor is not eligible for, and hereby waives any claim to, any benefits provided by the Client to its employees, including health insurance, vacation pay, or retirement plans.
5. Equipment and Tooling
While the Contractor may utilize the Client's heavy machinery (e.g., CNC Mills, Lathes), the Contractor is expected to provide their own precision measuring instruments (calipers, micrometers) and specialized cutting tools unless otherwise specified. The Contractor is responsible for any damage to the Client’s machinery resulting from gross negligence or intentional misconduct.
6. Confidentiality and Intellectual Property
The Contractor agrees to keep all drawings, customer lists, and proprietary processes confidential. Any G-code, jigs, or fixtures developed during the course of this Agreement shall be considered 'Work Made for Hire' and shall remain the exclusive property of the Client unless otherwise agreed in writing.
7. Termination
Either party may terminate this agreement with [Number] days written notice. In the event of termination, the Contractor shall be paid for all work completed and accepted up to the termination date.
Machine Damage & Liability
If a contractor crashes a $250k CNC mill, without this agreement, the shop owner may have no legal recourse for repairs or lost production time.
Intellectual Property & G-Code
Without a 'Work Made for Hire' clause, a contractor could potentially claim ownership of the custom programs and jigs they developed on your machines.
IRS 1099 Reclassification
If the contractor lacks autonomy in their 'feeds and speeds' or work hours, the IRS may reclassify them as an employee, demanding years of back-dated payroll taxes.
What is a Machinist Independent Contractor Agreement?
A Machinist Independent Contractor Agreement is a legal contract defining the relationship between a client and a freelance machinist. It establishes the machinist's 1099 status, outlines the scope of machining work, specifies tool ownership, and shifts tax and insurance liabilities to the contractor rather than the hiring company.

Why Machinists need a clear independent contractor agreement
In the world of precision machining, the line between a specialized service provider and an employee can be thin. A Machinist Independent Contractor Agreement is vital because it codifies the 'Right to Control'—or lack thereof. For a machinist, it protects their business autonomy and right to work for multiple clients. For the hiring shop, it serves as a shield against the Department of Labor by explicitly stating that the contractor is responsible for their own self-employment taxes, insurance, and specialized tooling. Beyond tax compliance, this document manages the high-risk nature of machining by defining who is liable for scrapped raw materials, broken end mills, or machine downtime. Without this specific document, a shop owner effectively assumes all professional and financial liability for a third-party's technical errors.
Real-world scenario
A precision job shop hired 'Contractor Carl' to help clear a backlog of titanium components. Carl worked on-site but used his own expensive custom boring bars and programmed the tool paths himself. When the contract ended, Carl filed for unemployment benefits, claiming he was a full-time employee. Because the shop owner had a signed Machinist Independent Contractor Agreement, they were able to present the state labor board with clear evidence: the agreement stated Carl had full autonomy over his methods, provided his own specialized tooling, and was paid a flat rate per completed batch rather than an hourly wage. The state ruled in favor of the shop owner, saving them over $20,000 in potential back-taxes and unemployment insurance hikes. The document proved that Carl was a separate business entity, not a dependent worker.
🛡️ What this independent contractor agreement covers:
- ✓Definition of Machining Services (CNC, Manual, Programming, or Prototyping)
- ✓Quality Standards and Tolerance Compliance (e.g., ISO or Aerospace standards)
- ✓Independent Contractor Status Affirmation
- ✓Material and Tooling Responsibility Clause
- ✓Indemnification and Professional Liability Coverage
- ✓Confidentiality and Trade Secret Protection
Best practices for Machinists
Define Scrap Thresholds
Clearly state what percentage of material scrap is acceptable before the contractor becomes financially responsible for raw material costs.
Verify COI
Always require a Certificate of Insurance (COI) from the machinist to ensure they carry their own general liability before they touch your machines.

Frequently Asked Questions
Can the machinist use my shop's CNC machines and still be a contractor?
Yes, provided they maintain 'control' over how the work is performed and use their own small tools (measuring equipment, specialized cutters) and possess a separate business entity.
Who owns the G-code programs created during the contract?
Typically, the agreement should specify that the hiring client owns the code as 'Work Made for Hire,' though some contractors may negotiate to keep their proprietary macros.
