Financial planning
for gig workers and freelancers.

Irregular income, no employer benefits, no 401(k) match, 15.3% self-employment tax on top of income tax. Gig work and freelancing create a unique set of financial challenges that no W-2 playbook fully addresses. This page covers the tax system, health insurance options, retirement accounts, and the budgeting system that handles variable income.

This page covers US federal tax and benefits rules. Other countries have their own self-employment frameworks (UK Self Assessment, Canadian self-employed CPP/EI, Australian PAYG instalments) with different mechanics.

Section 1 · The core problems

PROBLEM 1 · SELF-EMPLOYMENT TAX

W-2 employees pay 7.65% in FICA. The employer pays the other 7.65%. Gig workers pay both sides: 15.3% on net earnings up to the Social Security wage base ($176,100 in 2026), then 2.9% Medicare beyond, plus 0.9% Additional Medicare above $200k (single) / $250k (MFJ). You can deduct half of the SE tax from your income but you still pay the full amount verify×DON'T TRUST, VERIFYClaim: Self-employment tax structure: 15.3% to wage base, 2.9% above, plus 0.9% Additional Medicare.Verify at: IRS SE Tax page ↗Wage-base figures and rates published annually. The half-deduction applies above-the-line on Schedule 1..

PROBLEM 2 · NO EMPLOYER BENEFITS

No employer health insurance contribution
No 401(k) match (you fund both sides if you have a Solo 401(k))
No paid leave, paid time off, or sick pay
No unemployment insurance (independent contractors typically don't qualify)

PROBLEM 3 · IRREGULAR INCOME

Budgeting and tax planning require different systems than fixed-salary income. A good month and a slow month a few months apart can make a steady spending pattern feel chaotic.

THE GIG-WORKER PREMIUM AT $60K NET INCOME

Federal taxes for a single filer:

Gig worker: SE tax ~$8,478 + income tax on AGI ~$12,267 = ~$20,745 (~34.6%)
W-2 worker: FICA ~$5,900 + income tax ~$6,617 = ~$12,517 (~20.9%)
The gig worker pays approximately $8,200 more at the same nominal income.

This is why gig income should be priced at least 30% above the W-2 equivalent for the same total compensation, before accounting for missing benefits.

Section 2 · The tax system

Quarterly estimated taxes

If you expect to owe $1,000 or more in taxes, you must pay quarterly via Form 1040-ES. Due dates: April 15 (Q1), June 15 (Q2), September 15 (Q3), January 15 (Q4) of the following year verify×DON'T TRUST, VERIFYClaim: Quarterly estimated tax due dates are 4/15, 6/15, 9/15, and 1/15.Verify at: IRS Form 1040-ES ↗Note that quarters are not equal length; missing a deadline triggers underpayment penalty calculated quarterly.. The underpayment penalty is calculated as approximately 8% annualized interest on each quarter's underpayment.

The safe harbor: pay 100% of last year's tax liability in withholding or estimated payments (110% if AGI over $150,000). If you meet this, no underpayment penalty regardless of what you owe at filing. The safe harbor is the simplest way to handle a rising-income year.

Tax set-aside rule of thumb

Set aside 25-30% of every payment you receive into a separate savings account. That account is for the IRS, not for you. Pay quarterly estimates from that account.

Deductible business expenses

Home office (a dedicated space used only for business): actual expenses or simplified method ($5/sqft up to 300 sqft) verify×DON'T TRUST, VERIFYClaim: Home-office simplified method is $5/sqft up to 300 sqft.Verify at: IRS Form 8829 ↗Form 8829 details actual-expenses method; simplified method is described in Pub 587..
Vehicle (business use): standard mileage rate (67 cents/mile in 2024, updated annually) or actual expenses.
Health insurance premiums: 100% deductible above-the-line for self-employed.
Half of SE tax: deductible above-the-line.
Retirement contributions: Solo 401(k), SEP IRA, or SIMPLE IRA are deductible. See Section 4.
Equipment, software, subscriptions used for work: Schedule C deductions.
QBI Deduction (through 2025): up to 20% of qualified business income (subject to income phase-outs and service-business limits). Scheduled to expire after 2025; see /tcja-sunset/.

Section 3 · Health insurance

ACA Marketplace. Health insurance exchange for people. Premium tax credits based on income. For variable-income gig workers, estimate conservatively to avoid having to pay back credits at tax time. See healthcare.gov.
Spouse's employer plan. If married to a W-2 employee with employer health coverage, joining their plan is often more cost-effective than the individual market.
HDHP + HSA combination. A high-deductible marketplace plan paired with a Health Savings Account. Lower premium, triple-tax-advantaged HSA, effective for healthy people with low expected medical costs. See the HSA calculator.
Health-sharing ministries. Not insurance. Members share medical costs voluntarily. Lower monthly cost but no ACA protections, no guaranteed issue, and pre-existing conditions often excluded. Research carefully; recovery on a major claim is not guaranteed.
Freelancers Union or trade-association plans. Some industries have group-purchasing options that beat the individual market.

Section 4 · Retirement accounts for the self-employed

SOLO 401(K) · MOST POWERFUL

Contribute as both employee ($23,500 in 2025) and employer (up to 25% of net self-employment income). Total potential up to $70,000/year (more with catch-up at 50+). Roth option available. Requires no employees other than a spouse verify×DON'T TRUST, VERIFYClaim: 2025 Solo 401(k) total limit ~$70,000 plus catch-up.Verify at: IRS Solo 401(k) page ↗415(c) total limit and 402(g) employee deferral are inflation-adjusted annually.. See /solo-401k/.

SEP IRA · SIMPLER

Contribute up to 25% of net self-employment income, max $70,000 (2025). No employee contribution side, only employer. No Roth option. Extremely simple to set up. Good for backup if Solo 401(k) administration feels heavy.

SIMPLE IRA · FOR THOSE WITH EMPLOYEES

Requires employer match. Lower contribution limits than Solo 401(k). Not typically the right choice for solo operators.

ROTH IRA · ALWAYS AVAILABLE

Up to $7,000/year ($8,000 if 50+) in 2025. Available regardless of which other plan you have. Always max this before optimizing the SEP IRA; Roth flexibility is valuable. Subject to income limits; backdoor Roth is the workaround.

Section 5 · Budgeting with irregular income

The fixed-floor-first method

List all fixed monthly expenses (rent, utilities, insurance, debt minimums, recurring subscriptions).
Calculate the minimum monthly income needed to cover them.
Build a buffer of 3 months of fixed expenses in a savings account.
Treat the buffer as a salary-smoothing account.

The system

All client/customer payments go into a business account.
Transfer a fixed monthly "salary" to your personal checking each month, regardless of what came in. Set the salary at what you need to live on, not what you earned last month.
Good months: the buffer grows. Bad months: the buffer covers.
The buffer never has to think about feast-and-famine; you do not.

The tax account

Transfer 25-30% of every payment to a dedicated savings account immediately when the payment hits your business account. That money is not yours; it belongs to the IRS. Pay quarterly estimates from that account. The discipline of treating the tax money as gone removes the temptation to spend it during good months.
