Self-employment tax in Pennsylvania: the basics

If you earn $400+ in net self-employment income in Pennsylvania, you owe Self-Employment tax (15.3%): 12.4% for Social Security (on net earnings up to $184,500 in 2026) + 2.9% for Medicare (no cap). An additional 0.9% Medicare surtax kicks in above $200,000 (single) / $250,000 (MFJ).

Unlike W-2 employees who split FICA 50/50 with their employer, you pay both halves. The good news: you deduct 50% of SE tax on your federal 1040 as an above-the-line adjustment.

Quarterly estimated tax schedule

Federal quarterly deadlines for tax year 2026:

Q1 (Jan 1 – Mar 31): due April 15, 2026
Q2 (Apr 1 – May 31): due June 16, 2026
Q3 (Jun 1 – Aug 31): due September 15, 2026
Q4 (Sep 1 – Dec 31): due January 15, 2027

Missing payments triggers the IRS "underpayment penalty" (~5–8% annualized interest).

Pennsylvania specific considerations

Self-employed tax FAQ for Pennsylvania

How is self-employment tax different from regular W-2 employment in Pennsylvania?

Self-employed individuals in Pennsylvania pay the full 15.3% SE tax (12.4% Social Security + 2.9% Medicare) themselves — W-2 employees only pay half (7.65%), with the employer paying the other half. You can deduct 50% of your SE tax when calculating your federal income tax. The calculator above shows W-2 estimates; multiply FICA by ~2x to approximate SE tax exposure.

Do I need to pay quarterly estimated taxes in Pennsylvania?

If you expect to owe $1,000 or more in federal tax (after withholdings), yes. Quarterly estimated tax deadlines are April 15, June 15, September 15, and January 15. Pennsylvania also requires quarterly state estimated payments if you owe $500+ in state tax.

What expenses can I deduct as a Pennsylvania freelancer?

Common deductions include: home office (simplified method = $5 per sq ft up to 300 sq ft), business mileage ($0.70 per mile in 2025), health insurance premiums, retirement contributions (SEP-IRA, Solo 401(k)), continuing education, software subscriptions, phone/internet proportional to business use. Keep receipts and records for all of them.

Should I form an LLC or S-Corp in Pennsylvania?

For freelancers earning under ~$80K, a single-member LLC (taxed as sole proprietor by default) is usually enough and simpler. Above that, an S-Corp election can save on SE tax by paying yourself a reasonable salary + distributions. Pennsylvania has standard LLC filing requirements — expect annual fees and paperwork. Consult a CPA before deciding.

How much should I set aside for taxes as a 1099 worker in Pennsylvania?

A safe rule of thumb is 25–30% of gross income set aside in a separate account. This covers federal income tax (10–24% for most freelancers), SE tax (15.3%), and Pennsylvania's flat 3.07% state tax. Higher earners may need to set aside 35–40%.
