Should I Start an LLC for My CNC Machining Business?

Starting a limited liability company (LLC) for your CNC machining business can provide several benefits. 

Most importantly, an LLC structure offers limited liability to its owners, which can protect their personal assets from lawsuits and creditors.

For a CNC machining business, lawsuits can arise from things like commercial property disputes with insurance providers (e.g., in order to repair, maintain, and replace manufacturing equipment, etc.), as well as from personal injury claims.  

LLCs are also affordable, highly flexible (from a tax point-of-view), and can make your CNC machining business seem more credible.

Recommended: Use Northwest to form an LLC for $29 (plus state fees).

Do I Need an LLC for a CNC Machining Business?

LLCs are a simple and inexpensive way to protect your personal assets and save money on taxes.

You should form an LLC when there's any risk involved in your business and/or when your business could benefit from tax options and increased credibility.

LLC Benefits for a CNC Machining Business

By starting an LLC for your CNC machining business, you can:

  • Protect your savings, car, and house with limited liability protection
  • Have more tax benefits and options
  • Increase your business’s credibility

Limited Liability Protection

LLCs provide limited liability protection. This means your personal assets (e.g., car, house, bank account) are protected in the event your business is sued or if it defaults on a debt.

CNC machining businesses will benefit from liability protection because of the risk of someone getting injured in their place of business. 

Example 1: An employee at your CNC machining business is injured after a milling machine broke as he was operating it. As a result, the employee sued your business for this personal injury on the basis that he was injured because your company had negligently maintained the machine. In the ensuing lawsuit, you are precluded from being personally responsible for damages by limited liability.

Example 2: Your CNC machining business produces the set of gears that are used in a lawnmower. One of these small pieces malfunctions while a customer is operating the lawnmower, causing the customer to sustain great injury. This led to your business receiving notice of a product liability lawsuit filed against it for these defective gears. Your personal assets would be protected from any obligation to pay damages the court may impose on your business.

Example 3: A company hires your CNC machining business to produce a number of specific parts by a certain date. Due to unforeseeable circumstances, your business is unable to deliver these parts on time, which causes the company to suffer significant financial loss. As a consequence, your business is sued for breaching its contract. Limited liability protects your personal assets (such as your house and savings) from being used to satisfy any damages.

An LLC will also protect your personal assets in the event of commercial bankruptcy or loan default.

To maintain your LLC's limited liability protection, you must maintain your LLC's corporate veil.

LLC Tax Benefits and Options for a CNC Machining Business

LLCs, by default, are taxed as a pass-through entity, just like a sole proprietorship or partnership. This means that the business's net income passes through to the owner's individual tax return. 

The business’s net income is then subject to income taxes (based on the owner's tax bracket) and self-employment taxes.

Sole proprietorships and partnerships are taxed in a similar way to LLCs, but they do not offer limited liability protection or other tax options.

S Corp Option for LLCs

An S corporation (S corp) is an IRS tax status that an LLC can elect. S corp status allows business owners to be treated as employees of the business (for tax purposes).

S corp tax status can reduce self-employment taxes and will allow business owners to contribute pre-tax dollars to 401k or health insurance premiums.

The S corp status requires that the business pay the employee-owner(s) a reasonable salary for the work they perform. 

In addition, the business might need to spend more on accounting, bookkeeping, and payroll services. To offset these costs, you'd need to be saving about $2,000 a year on taxes.

We estimate that if a CNC machining business owner can pay themselves a reasonable salary and at least $10,000 in distributions each year, they could benefit from S corp status.

You can start an S corp when you form your LLC. Our How to Start an S Corp guide will lead you through the process.

Credibility and Consumer Trust

CNC machining businesses rely on consumer trust. Credibility plays a key role in creating and maintaining any business.

Businesses gain consumer trust simply by forming an LLC.

A growing business can also benefit from the credibility of an LLC when applying for small business loansgrants, and credit.
