The subcontractor vs. employee question is not just a tax question, though the tax consequences are real and serious. It’s a business design question. The structure you choose shapes the relationship you have with that person, the flexibility you maintain, the IP protections you hold, and the legal obligations you carry.
Most solos default to subcontractors because it feels simpler and cheaper. Sometimes it is. But subcontracting the wrong role, one that’s full-time, deeply embedded in client relationships, or handling sensitive intellectual property, creates legal exposure and operational fragility that cost more than the savings.
Use this framework to decide based on the role, not just the rate.
The 4-Axis Decision Matrix
Score each axis 1 (subcontractor) or 2 (employee). A total of 6-8 points indicates an employee. A total of 4-5 points indicates a subcontractor. A score of 4 with one axis at 2 warrants a more careful look at that axis.
Axis 1: Workload Predictability
Variable workload → subcontractor (score: 1) Predictable workload → employee (score: 2)
If the person’s work volume depends on whether you win specific projects, a subcontractor is the right structure. You engage them when you need them and not when you don’t. There’s no ongoing obligation on either side.
If the person is needed consistently, 30+ hours per week, every week, regardless of which specific projects you’re running, that’s full-time, predictable work. In most jurisdictions, engaging someone full-time on an ongoing basis under the legal label of “contractor” is misclassification. The IRS, HMRC, and equivalent agencies in other countries look at actual work patterns, not labels.
Axis 2: IP Sensitivity
Low IP sensitivity → subcontractor (score: 1) High IP sensitivity → employee (score: 2)
IP sensitivity has two components: confidentiality and ownership. If the person will have access to your client list, your proprietary methodologies, your pricing, or your unreleased work product, the stakes of that relationship are higher than a standard contractor engagement.
Employees have stronger legal obligations around IP and non-disclosure in most jurisdictions. Non-disclosure agreements with contractors are enforceable, but employees typically operate under more comprehensive and legally durable IP agreements as a condition of employment.
If your differentiation as a consultant depends on your methods, your client relationships, or your proprietary tools, and this person will be deeply embedded in that work, the added legal protection of an employee relationship is often worth the cost premium.
Axis 3: Time Commitment
Part-time need → subcontractor (score: 1) Full-time need → employee (score: 2)
This axis is the most practical. A designer you need for 10-15 hours per week on client projects is a natural subcontractor, they have other clients, they manage their own schedule, and you’re not their primary employer. An operations person who you need 40 hours per week is effectively a full-time role regardless of what you call them.
The test: if this person’s schedule is primarily organized around your needs, if you’re their primary income source, and if they’ve been working this way for 6+ months, you’re operating in employee territory from a practical and often a legal standpoint.
Axis 4: Growth Pace
Slow/moderate growth → subcontractor (score: 1) Fast scaling → employee (score: 2)
When you’re scaling fast, institutional knowledge becomes a competitive asset. An employee who grows with the business understands your clients, your methods, your standards, and your positioning. A subcontractor who rotates between clients doesn’t build that knowledge with the same depth.
More practically: fast-scaling businesses need reliability. A subcontractor can take a competing engagement that pulls them away from your priorities. An employee’s primary obligation is to you. At a period of high growth, that reliability premium is worth the higher cost.
The legal label you put on a hire doesn’t change how the IRS or equivalent tax authority categorizes the relationship. They look at the substance: who controls the work, who sets the hours, whose tools are used, whether the person works for multiple clients. Substance over form, always.
The Typical Progression
For most solo consultants, the path looks like this:
$0-$200K revenue: Subcontractors only. Work is project-based, cash is variable, and you don’t have the predictable revenue to justify an employee’s fixed cost. Use subcontractors for delivery support and admin.
$200K-$400K revenue: Primarily subcontractors with one potential conversion. If a subcontractor has been working 30+ hours per week consistently for 6+ months, it’s time to evaluate the misclassification risk and have a conversion conversation.
$400K+ revenue: First employee becomes viable. At this revenue level, you likely have a consistent monthly revenue base (from retainers or repeat clients) that justifies a fixed payroll cost. Your first employee is typically your most reliable subcontractor, converted.
This progression is not a rule, it’s a description of what works most often. A firm that built its business on productized services with predictable volume might reach employee territory earlier. A firm that lives project-to-project might stay with contractors longer.
The $5,000/Month Cost Comparison
Real numbers for a comparable $5,000/month spend:
Subcontractor at $5,000/month:
- Monthly cost: $5,000
- Your obligations: 1099 (US) / contractor invoice
- Their obligations: pay their own self-employment taxes
- Hours: variable, up to agreed limit
- IP ownership: defined in contractor agreement (negotiate carefully)
- Legal exposure if misclassified: back taxes, penalties, back pay
Employee at comparable total cost:
- Employee take-home: ~$4,100-$4,200/month
- Employer payroll taxes (US: ~7.65% FICA): ~$320/month
- Benefits (health, if applicable): $300-500/month
- Equipment, HR overhead: $100-200/month
- Total employer cost: $4,820-$5,220/month
The premium for employee status at this spend level is roughly $750-$1,000/month. That buys you:
- Full control over how work gets done
- Stronger IP protections
- Legal clarity on worker classification
- Primary loyalty and availability
- Ability to invest in training without risk they take the skill elsewhere immediately
Whether that $750-$1,000/month premium is worth it depends entirely on the role. For a core delivery hire doing sensitive client work, yes. For an occasional research assistant or designer you engage 8 hours per month, obviously not.
The Conversion Conversation
When you’re ready to convert a subcontractor to an employee, the conversation is direct: “You’ve been a core part of how I operate for [X months]. I want to formalize that, move you to an employee arrangement. That means [salary], [benefits], and [schedule commitment]. It also means you’d transition to exclusive arrangement with [company name].”
The hardest part of this conversation is the exclusivity ask. Many contractors work with multiple clients. Converting to an employee means asking them to close those other relationships, or at minimum, to make you their primary commitment. Not every contractor will accept. Some will prefer the flexibility of contractor status even at a lower effective rate.
If they decline the conversion and the work volume is genuinely full-time, you have two choices: accept the legal risk and management complexity of an informal full-timer (not recommended), or find someone willing to take the employee arrangement. A contractor who won’t commit to exclusivity when you need full-time coverage is not the right person for a full-time role.
A contractor who won’t accept employee terms when offered full-time work and fair compensation is telling you something about their commitment to your business. Take that information seriously before you build your delivery capacity around them.
The Non-Negotiable Contract Clauses for Subcontractors
If you’re engaging subcontractors (which most solos will), ensure your contractor agreement covers four things regardless of jurisdiction:
-
IP assignment: All work product created under the engagement belongs to you, not the contractor. Include a blanket assignment clause and a specific list of deliverable types.
-
Non-disclosure: Client names, project details, your methodologies, and your pricing are confidential. The NDA should survive termination of the contract.
-
Non-solicitation: The contractor cannot solicit your clients directly for 12-24 months after the engagement ends. This is especially important for subcontractors doing client-facing work.
-
Subcontracting limits: The contractor cannot further subcontract the work to a third party without your written approval. You hired them for their skills, not someone else’s.
Have an attorney in your jurisdiction review the agreement once. A $500 legal review of your contractor template is the cheapest insurance you can buy before scaling with subcontractors.
