Contractor at $140/hr + GST or Employee at $140,000 p.a.?
A Practical NZ Construction Industry Comparison from the Employer’s Viewpoint
For a construction company, the decision to engage a person as a "contractor" or employ them as a "permanent employee" should not be based only on the hourly rate or annual salary.
The correct decision depends on:
* Total cost to the business
* Level of control required
* Workload certainty
* Risk allocation
* Flexibility required
* Long-term value to the company
* Compliance with NZ employment and tax obligations
In New Zealand, the employer must consider the "real nature of the working relationship", not only what the agreement is called.
A person may be called a contractor, but if they are managed and controlled like an employee, the business may face employment-status risk.
Basic Cost Comparison
Contractor Option
A contractor charging: $140/hr + GST
Based on:
* 40 billable hours per week
* 46 working weeks per year
The annual contract cost may be approximately: $257,600 + GST per year
Permanent Employee Option
A permanent employee earning: $140,000 per annum
This appears substantially cheaper on paper.
However, the employer must also allow for additional employment-related costs and obligations.
Employer Costs and Obligations for a Permanent Employee
A permanent employee may create additional direct and indirect costs, including:
* Paid annual leave
* Paid sick leave
* Public holiday entitlements
* Employer KiwiSaver contributions, where applicable
* ACC levies
* Payroll administration
* HR management
* Training and supervision
* Company equipment
* Phone, laptop, software and systems
* Vehicle or fuel allowance, if provided
* Performance management
* Possible redundancy obligations
* Long-term fixed overhead commitment
The employee may cost less per hour, but the business carries a longer-term employment obligation.
Advantages of Permanent Employment
Permanent employment may be the better option where the company needs:
* Long-term consistency
* Internal control
* Team loyalty
* Continuity across projects
* Staff who follow company systems and procedures
* Client relationship management
* Project knowledge retained inside the business
* A person who forms part of the company’s long-term structure
The main benefit is "control".
The company can direct the employee’s work, hours, reporting, systems, priorities and internal responsibilities.
This is valuable where the role is ongoing and central to the company’s operation.
Disadvantages of Permanent Employment
The disadvantages include:
* The employee becomes a fixed overhead
* The company carries the cost during quiet periods
* There is less flexibility if workload decreases
* Performance issues may require formal management processes
* The company carries employment-law obligations
* Redundancy or restructuring may create additional cost
* The person may require ongoing training, supervision and management
Permanent employment can offer better value where workload is consistent, but it can become costly if workload becomes uncertain.
Advantages of Engaging a Contractor
A contractor may be useful where the company needs:
* Specialist expertise
* Short-term support
* Project-specific input
* Senior experience without long-term commitment
* Flexibility during busy periods
* Assistance with a defined problem or deadline
* Reduced fixed overheads
* Ability to scale resources up or down
The main benefit is "flexibility".
The company can engage the contractor for a specific scope, project, timeframe or deliverable without creating a permanent position.
Disadvantages of Engaging a Contractor
The disadvantages include:
* Higher hourly rate
* Less direct control over how the work is performed
* Less long-term loyalty to the business
* Project knowledge may leave with the contractor
* Availability may not be guaranteed
* The contractor may work for other clients
* The business may need to clearly define scope and deliverables
* Misclassification risk if the contractor is treated like an employee
A genuine contractor should not be managed in the same way as an employee.
If the company controls the contractor’s hours, work methods, leave, reporting, systems, exclusivity and day-to-day activities in the same way as staff, the arrangement may create legal and commercial risk.
When Contracting Makes Sense
Contracting at $140/hr + GST may be justified where:
* The workload is project-based
* The expertise required is specialised
* The duration of the work is uncertain
* The company does not want a long-term payroll commitment
* The output can be clearly defined
* The contractor carries their own business risk
* The person can deliver measurable results
* The company needs senior expertise immediately
* The workload may reduce after the project is complete
In this situation, the higher hourly cost may be acceptable because the company is buying flexibility, experience and reduced long-term commitment.
When Permanent Employment Makes Sense
Permanent employment at $140,000 p.a. may be better where:
* The role is ongoing
* The company has consistent long-term work
* The person needs to be integrated into the business
* The company wants direct control
* The position is part of the long-term structure
* The person must follow internal procedures
* Client relationships need continuity
* Project knowledge must remain within the company
* The business wants loyalty and accountability
In this situation, the lower annual salary may offer better value because the person becomes part of the company’s long-term operational capacity.
Important Construction Industry Considerations
In construction, this decision is especially important because:
* Margins are often tight
* Programmes change frequently
* Council delays can affect progress
* Clients change scope
* Subcontractors cause delays
* Cashflow is often under pressure
* Workload can fluctuate from month to month
* Senior expertise is expensive but often critical
* Poor resourcing decisions can create contractual and financial risk
A contractor may cost more per hour, but can be engaged only when required.
An employee may cost less per hour, but becomes a fixed overhead whether the workload is available or not.
The Key Commercial Question
The decision should not simply be:
Which option is cheaper?
The better question is:
What does the business actually need?
Does the company need:
* Time?
* Expertise?
* Flexibility?
* Control?
* Continuity?
* Long-term capacity?
* Short-term project support?
Each option has a place.
The mistake is choosing one purely because it looks cheaper on paper.
Practical Conclusion
From an employer’s viewpoint:
A contractor at $140/hr + GST may be the better option where:
* Workload is uncertain
* The role is project-specific
* Specialist expertise is required
* The company wants flexibility
* Long-term employment commitment is not justified
A permanent employee at $140,000 p.a. may be the better option where:
* Workload is consistent
* The role is central to the business
* The company needs control and continuity
* The person will be part of the long-term structure
* Project and client knowledge must stay inside the company
The cheapest option is not always the best commercial decision.
The best option is the arrangement that properly matches the company’s workload, risk, responsibility and required commercial outcome.
In construction, the real issue is not whether $140/hr + GST is too high or whether $140,000 p.a. is too low.
The real issue is whether the business is buying:
Time, expertise, control, flexibility, or long-term value.
