Self-Employment Tax in Pennsylvania (2026)

Fact-checked by the LegalGlass editorial team against primary sources · Published Aug 6, 2026 · Last updated Aug 6, 2026

Self-employment tax is 15.3% - 12.4% for Social Security up to the annual SSA wage base plus 2.9% for Medicare with no cap - computed on Schedule SE and paid to the IRS through quarterly estimated payments. That is a federal tax; Pennsylvania has no separate self-employment tax. Pennsylvania instead taxes the net profit from your business or profession at a flat 3.07% personal income tax rate, and it does not allow the federal one-half-of-SE-tax deduction at the state level.

What Self-Employment Tax Is (15.3%)

Self-employment tax is how people who work for themselves pay into Social Security and Medicare. When you are an employee, your employer withholds your share of these payroll taxes and pays a matching share on your behalf. When you are self-employed - a sole proprietor, an independent contractor, a partner, or the owner of a single-member LLC taxed as a disregarded entity - there is no employer, so you pay both halves yourself. That combined rate is 15.3%.

The tax applies to your net earnings from self-employment, generally your business profit after expenses, and it is separate from income tax. In other words, a self-employed Pennsylvanian can owe federal income tax, federal self-employment tax, Pennsylvania personal income tax, and sometimes a local earned income tax, all on the same underlying profit. This guide explains how each layer works and where Pennsylvania's rules differ from the federal ones. It is educational information, not tax advice - see the broader business tax hub and our self-employment tax calculator to model your own numbers.

Social Security and Medicare Components

The 15.3% rate is really two taxes stacked together. The larger piece is the Social Security portion at 12.4%. This portion applies only up to an annual ceiling called the Social Security wage base (also called the contribution and benefit base), which the Social Security Administration adjusts each year for inflation. Once your combined wages and net self-employment earnings reach that year's base, no further Social Security tax is due for the year. Because the figure changes annually, confirm the current wage base with the SSA rather than relying on a fixed number.

The smaller piece is the Medicare portion at 2.9%, and it has no cap - every dollar of net self-employment earnings is subject to it. There is also a taxpayer-friendly mechanic built into the calculation: you first multiply your net profit by 92.35% before applying the 15.3% rate, which approximates the employer-side deduction an employee effectively gets. The result is reported on Schedule SE. A common way to think about the split is shown below.

The Additional Medicare Tax (0.9%)

Higher earners owe one more layer. The Additional Medicare Tax adds 0.9% on self-employment income and wages above threshold amounts: $200,000 for single filers and $250,000 for married taxpayers filing jointly (the threshold is $125,000 for married filing separately). This is on top of the regular 2.9% Medicare portion, so the marginal Medicare rate above the threshold effectively becomes 3.8% on self-employment earnings.

The Additional Medicare Tax is reported on Form 8959 and reconciled on your Form 1040. It is not matched by any "employer" share because you are self-employed, and unlike the Social Security portion it is not affected by a wage base ceiling. For most small Pennsylvania businesses this layer will not apply, but it matters for profitable owner-operators and for households where combined earnings from a job and a side business push past the threshold.

Computing and Paying: Schedule SE and Quarterly Estimates

You calculate self-employment tax on Schedule SE, filed with your federal Form 1040. Your business profit itself is usually reported first on Schedule C (for a sole proprietor or single-member LLC) or on a partnership return, and that profit flows into Schedule SE. One important relief: for federal income tax, you deduct one-half of your self-employment tax as an adjustment to income. That deduction reduces your federal taxable income, though it does not reduce the self-employment tax itself.

Because no employer withholds tax from your pay, the IRS generally expects you to pay as you go through quarterly estimated payments using Form 1040-ES. Those estimates should cover both your income tax and your self-employment tax; underpaying can trigger a penalty. Pennsylvania likewise expects quarterly estimated payments of state income tax on your net profit when enough is not otherwise withheld. Keeping a percentage of every payment aside for taxes, and getting a free federal EIN if you hire or need one, are practical habits; if you later form an entity, see how to form an LLC in Pennsylvania and Pennsylvania LLC tax filing.

Pennsylvania State Tax: 3.07% on Net Profits

Pennsylvania handles the self-employed differently from the federal government in two ways that matter. First, Pennsylvania has no separate self-employment tax - the 15.3% is purely federal. Second, Pennsylvania's personal income tax is a flat 3.07%, and the income from your business is taxed under the class of income called net profits from a business, profession, or farm. Pennsylvania taxes that net profit directly.

The key catch is that Pennsylvania's rules for computing that net profit are its own. Notably, Pennsylvania does not allow the federal deduction for one-half of self-employment tax when it figures your state taxable profit, and its rules on which expenses and depreciation methods are allowable can differ from the federal treatment. The practical effect is that your Pennsylvania taxable net profit is often not identical to your federal Schedule C profit. Because a single-member LLC is generally disregarded for both federal and Pennsylvania income tax, the owner reports the profit on the personal return either way - an S-corporation election is one route some owners use to change how earnings are taxed as the business grows. Confirm the current rate and rules with the Pennsylvania Department of Revenue before filing.

Local Earned Income Tax (EIT)

Pennsylvania is unusual for its layer of local taxation. Most municipalities and school districts levy a Local Earned Income Tax (EIT) that applies to earned income and to net profits from a business or profession. Combined local EIT rates are commonly around 1%, though they vary meaningfully by locality, and some places - most prominently Philadelphia, with its own wage and business taxes - operate under different local systems entirely.

The EIT is typically administered by a regional tax collector rather than the state, and you generally owe it based on where you live (and sometimes where you work). Self-employed residents usually file an annual local return and may owe quarterly local estimates as well. Because rates, collectors, and rules differ from one municipality to the next, look up the specific rate for your residence and work location, and factor the EIT into your total tax picture alongside federal self-employment tax and the state's 3.07%.
