A common and expensive miscalculation is leaving a $60,000 job for freelance work at $60,000 of billings and expecting to be in the same position.
You won’t be. The gap is large, and most of it isn’t obvious until the first tax bill.
You now pay both halves of FICA
As an employee, you split Social Security and Medicare with your employer. You pay 7.65%, and they pay a matching 7.65% that never appears on your pay stub.
Self-employed, you are both parties. That is 15.3% of net self-employment earnings:
- 12.4% Social Security, up to the annual wage base
- 2.9% Medicare, uncapped
- Plus 0.9% additional Medicare above $200,000
Two mitigations soften it, and both are real:
- The tax applies to 92.35% of your net earnings, not 100%. The adjustment approximates the employer’s share being a business expense.
- You deduct half of the self-employment tax from your income for income-tax purposes. It does not reduce the SE tax itself, but it reduces income tax.
Even after both, you pay meaningfully more than you did as an employee for identical earnings.
And income tax on top
Self-employment tax is separate from and additional to income tax. You owe both.
The mitigation here is significant: business expenses reduce your net earnings before either tax applies. Legitimate expenses lower both your SE tax and your income tax. They include equipment, software, a home office meeting the exclusive-use test, mileage, professional insurance and health premiums.
The Qualified Business Income deduction may also allow up to 20% of qualified business income to be deducted, subject to income thresholds and business type. It is substantial, so it is worth understanding properly or asking a professional about.
Quarterly estimated payments
Nobody withholds for you now. The IRS expects payment through the year, in four instalments, on 15 April, 15 June, 15 September and 15 January.
Miss them and you owe an underpayment penalty even if you pay the full amount in April. The penalty is interest-based, so it isn’t catastrophic, but it is avoidable.
Safe harbour protects you. Pay at least 100% of last year’s total tax (110% if your prior-year adjusted gross income exceeded $150,000) and no penalty applies, however much you end up owing. For a first year of self-employment with unpredictable income, plan around this rule.
The practical approach is to set aside 25-35% of every payment as it arrives, in a separate account, and pay quarterly from it. Money that sits in your main account gets spent.
What else you are now buying
Beyond tax, the employer was paying for things you did not see:
- Health insurance. Employer plans average well over $600 a month in employer contribution for individual coverage and far more for family. On the individual market you pay all of it, though self-employed health insurance premiums are generally deductible.
- Retirement match. A 6% match on $60,000 was $3,600 a year of free money, and it is gone.
- Paid time off. Employees are paid for roughly ten holidays and two to four weeks of leave. As a freelancer, a day not worked is a day not paid, which is roughly 30 unpaid days a year against an employee’s schedule.
- Unemployment insurance, which you generally cannot claim.
- Disability and life cover, if the employer provided it.
- Equipment, software, phone and internet, now yours. They are deductible but still an outlay.
- Unbillable time: sales, invoicing, admin, chasing payment. Most freelancers bill 60-70% of their working hours at best.
What rate that implies
To match a $60,000 salary you need considerably more than $60,000 of billings.
| Item | Amount |
|---|---|
| Target take-home equivalent | $60,000 |
| Extra FICA (employer half) | +$4,600 |
| Health insurance | +$7,000 |
| Lost retirement match | +$3,600 |
| Unpaid time off (~30 days) | +$7,000 |
| Equipment and overhead | +$3,000 |
| Required billings | ~$85,000 |
That is before allowing for unbillable hours. If you bill 65% of your working time, an $85,000 target across roughly 1,350 billable hours is about $63 an hour, against an employee’s nominal $29.
Freelancers use 1.5× to 2× their employee hourly rate as a rule of thumb, and this is where it comes from. The multiple only brings you level with what the employer was paying you.
Retirement limits are higher
Here you gain an advantage. Self-employed retirement accounts have far higher limits than a standard 401(k):
- SEP-IRA: up to 25% of net self-employment earnings, to a substantial annual cap. It is simple to open and administer.
- Solo 401(k): you contribute as both employee and employer, which usually allows more than a SEP at moderate income levels, and it supports a Roth option.
- SIMPLE IRA: lower limits, but straightforward if you have employees.
For a profitable freelancer these allow sheltering considerably more than an employee can.
The checklist
- Set aside 25-35% of every payment in a separate account.
- Pay quarterly estimates on the four dates, and use safe harbour to avoid penalties.
- Track every deductible expense from day one. Reconstructing them later is miserable and usually incomplete.
- Price at 1.5-2× your employee hourly rate, not at parity.
- Buy your own health cover and deduct the premiums.
- Open a SEP or Solo 401(k) once there is profit to shelter.
- Get a CPA for the first year. Self-employment tax, QBI and entity choice are where professional advice pays for itself several times over.
