Contractor vs Permanent: Complete Comparison
Should you go contracting or stay permanent? A detailed comparison of pay, benefits, taxes, and lifestyle for UK and US workers.
Quick Answer: Which is Better?
Neither is universally better - it depends on your circumstances. Contractors earn more (30-50% higher day rate) but sacrifice job security, benefits, and must handle their own taxes. Permanent employees have stability but lower earning potential. Choose based on your risk tolerance, career stage, and lifestyle preferences.

Lifestyle Factors to Consider
Income Stability
Variable income. May have gaps between contracts. Need emergency fund of 3-6 months expenses.
Predictable monthly salary. Easier budgeting and financial planning.
Consider: How comfortable are you with uncertainty? Do you have savings to handle gaps?
Career Progression
No promotions, but wide experience across companies. Build expertise as specialist. Need to self-market.
Clear ladder, internal promotions, company invests in your development.
Consider: Do you want depth in one company or breadth across many?
Working Relationships
Always the outsider. Shorter-term relationships. Less politics but also less belonging.
Deep relationships, team belonging, company culture for better or worse.
Consider: How important is workplace community to you?
Retirement Planning
Self-funded pension. Can be more tax-efficient but requires discipline.
Employer contributions. Often 3-6% match on top of salary.
Consider: Are you disciplined enough to save 15-20% for retirement yourself?
Work-Life Balance
Can take extended breaks between contracts. But no paid holiday.
Guaranteed 20-30 days holiday. Sick pay protection.
Consider: Do you value flexibility to take unpaid breaks, or security of paid leave?

Frequently Asked Questions
How much more do contractors earn than permanent employees?
Contractors typically charge 30-50% more in day rate equivalent compared to permanent salaries. However, after accounting for self-funded benefits (pension, holiday, insurance) and time between contracts, the real premium is often 10-30%. Inside IR35 contractors may earn similar to permanent employees after tax.
What is IR35 and how does it affect UK contractors?
IR35 is UK legislation that determines if a contractor is genuinely self-employed or effectively an employee for tax purposes. If caught by IR35 (inside IR35), you pay similar taxes to an employee. Key factors include substitution rights, control over work, and integration into the client organisation. Being inside IR35 reduces take-home pay by approximately 20-30%.
Can contractors get mortgages?
Yes, but it is harder. Most lenders require 2+ years of accounts or SA302 tax returns. Some specialist lenders offer mortgages based on day rate rather than accounts. Permanent employees can typically get mortgages immediately with payslips. If you plan to buy property, consider establishing your contracting track record first.
What is the difference between 1099 and W-2 in the US?
1099 workers are independent contractors who pay self-employment tax (15.3%) and receive no benefits. W-2 employees have taxes withheld by employers, receive benefits (health, 401k), and have employment protections. 1099 workers can deduct business expenses but must handle all tax payments themselves.
How do contractors handle holiday and sick pay?
Contractors do not receive paid holiday or sick pay - these must be self-funded. Most contractors factor this into their rate (typically adding 10-15% to cover 25-30 days annual leave equivalent). Some maintain an emergency fund for illness. When pricing your rate, include these hidden costs.
Is contracting right for me if I am early in my career?
Generally, contracting works better with 3+ years experience. Early career, permanent roles offer training, mentorship, and career foundations that contracting lacks. Build skills and network first, then consider contracting when you have expertise clients will pay premium rates for.
What happens to my pension as a contractor?
As a contractor, you fund your own pension. UK contractors can use SIPP (Self-Invested Personal Pension) with tax relief up to £60,000/year. US 1099 contractors can use SEP-IRA or Solo 401k with higher contribution limits than standard 401k. The discipline is on you, but contribution limits are often more generous.
How do I set my contractor day rate?
Calculate your desired annual equivalent salary, add 20-30% for self-funded benefits (pension, holiday, insurance), add 10-15% for gaps between contracts, then divide by 220-230 working days. Research market rates for your skills and location. In the UK, permanent salary x 1.5 / 220 is a rough starting point for day rates.
