Philadelphia self-employed workers pay federal SE tax and federal income tax, plus Pennsylvania state income tax (Flat 3.07%). Pennsylvania has one of the lowest flat income tax rates in the nation at 3.07%. However, many municipalities impose local earned income taxes of 1% to 3.9% (Philadelphia).

The federal SE tax rate is 15.3% (12.4% Social Security plus 2.9% Medicare), the same in Philadelphia as everywhere. It applies to 92.35% of net profit; Social Security stops at $176,100 of net earnings.
Pennsylvania taxes self-employment income as ordinary income (Flat 3.07%), so Philadelphia freelancers owe state tax on top of federal.
On $60,000 of net profit in Philadelphia, estimated total tax (SE plus federal plus state) is about $14,382, or roughly $3,595 per quarter.
Philadelphia levies a city wage tax of about 3.75% on the wages of residents (and roughly 3.44% on non-residents who work in the city). The calculators on this page show federal, Pennsylvania, and FICA amounts, so Philadelphia residents should add the city wage tax on top. Philadelphia levies the Business Income and Receipts Tax (BIRT), combining a tax on gross receipts with a tax on net income, and requires a Commercial Activity License. Part of the receipts base is exempt, but nearly every business must register and file, so budget for this on top of the Pennsylvania LLC filing fee.
Business expenses that lower net profit (equipment, software, home office, mileage) reduce both SE tax and income tax. The deductible half of SE tax, self-employed health insurance, and retirement contributions reduce income tax.
