If you are self-employed in the US and expect to owe $1,000 or more in tax for the year, the IRS wants the money in four installments — not one lump sum in April. Miss them and you owe an underpayment penalty even if you pay in full later.
Estimate your number with the Self-Employment Tax Calculator or the Freelancer Tax Calculator.
What you actually owe on freelance income
- Self-employment tax: 15.3% on 92.35% of net profit — 12.4% Social Security (up to the annual wage base) plus 2.9% Medicare (no cap).
- Federal income tax at your marginal bracket, applied to net profit after the deductible half of SE tax and any QBI deduction.
- State income tax where applicable — zero in TX, FL, WA, NV, TN, SD, WY, AK; up to double digits in CA and NY.
The half of SE tax you can deduct is an above-the-line deduction, which softens the headline 15.3% somewhat. It does not eliminate it.
The set-aside percentage
A workable rule for most freelancers, applied to net profit (revenue minus business expenses), not gross revenue:
- Under ~$50K profit, no state tax: set aside 25–28%.
- $50K–$120K profit, no state tax: 28–32%.
- $50K–$120K profit in a high-tax state: 33–38%.
- $120K+ profit in a high-tax state: 38–45%.
Move the money on receipt of every invoice into a separate account. The single most common freelancer failure mode is treating gross deposits as spendable income.
Due dates
- Q1 (Jan 1 – Mar 31): due mid-April.
- Q2 (Apr 1 – May 31): due mid-June. Note this is a two-month period, not three.
- Q3 (Jun 1 – Aug 31): due mid-September.
- Q4 (Sep 1 – Dec 31): due mid-January of the following year.
Safe harbor: the rule that removes the guesswork
You avoid the underpayment penalty if your total payments for the year hit either:
- 90% of the current year's actual tax liability, or
- 100% of last year's total tax — 110% if last year's AGI was above $150,000.
For creators and freelancers with volatile income, prior-year safe harbor is the sane default: take last year's total tax, multiply by 1.0 (or 1.1 above the AGI threshold), divide by four, pay that. You may overpay or underpay against actual liability, but you are penalty-proof.
Worked example
- Gross freelance revenue: $95,000.
- Business expenses (software, equipment, home office, travel): $15,000 → net profit $80,000.
- SE tax: 92.35% × $80,000 = $73,880 × 15.3% ≈ $11,304.
- Deduct half of SE tax ($5,652) plus the standard deduction, apply brackets → federal income tax roughly $8,000–$9,500 for a single filer with no other income.
- Total federal ≈ $19,500–$21,000 → about $5,000 per quarter, before any state tax.
Deductions freelancers routinely miss
- QBI deduction — up to 20% of qualified business income, subject to income thresholds and business-type limits.
- Home office — simplified method at a fixed rate per square foot, or actual expenses.
- Self-employed health insurance premiums, deductible above the line.
- Retirement contributions — a SEP-IRA or solo 401(k) can shelter a large share of profit and is the biggest single lever available to a profitable freelancer.
- Mileage at the standard rate, with a contemporaneous log.
- Half of business meals with a documented business purpose.
Practical system
- Separate business checking account. No personal spending from it, ever.
- Third account for taxes. Transfer your set-aside percentage the day each invoice clears.
- Pay electronically through IRS Direct Pay or EFTPS on the due dates; keep the confirmation numbers.
- Reconcile quarterly, not annually — a 20-minute check each quarter catches profit swings before they become a penalty.
- Once profit clears roughly $60–80K, get a CPA to evaluate an S-corp election.
FAQ
What if my income is wildly uneven?
Either use prior-year safe harbor, or use the annualized income installment method so each payment reflects that period's actual earnings.
What if I also have a W-2 job?
You can increase withholding on the W-2 instead of making estimated payments. Withholding is treated as paid evenly across the year, which can retroactively cure an earlier shortfall.
Do I need to pay if I made $8,000 freelancing?
Net earnings of $400 or more trigger self-employment tax. Whether you must make quarterly payments depends on whether you expect to owe $1,000+ overall.
Does creator income from YouTube, TikTok or Patreon count?
Yes — ad revenue, sponsorships, gifts and memberships are all self-employment income. See the YouTube creator tax guide.
