Pennsylvania offers side hustlers a relatively straightforward tax situation with its flat 3.07% state income tax rate—one of the lowest flat rates in the nation. However, many Pennsylvania municipalities also levy local income taxes (called Earned Income Tax or EIT), which can add 1% to 3.75% depending on where you live. Pittsburgh and Philadelphia residents face the highest combined rates.

Pennsylvania Tax Guide

How Side Hustle Taxes Work in Pennsylvania

Pennsylvania uses a flat tax system, making calculations simpler than progressive-tax states:

**Pennsylvania state tax:** - Flat rate: 3.07% on all taxable income - No brackets—everyone pays the same percentage - Applies to net profits from self-employment

**Local Earned Income Tax (EIT):** - Philadelphia: 3.75% for residents - Pittsburgh: 3% for residents - Other municipalities: 0.5% to 3% - This is IN ADDITION to the state 3.07%

Combined rates in major cities: - Philadelphia residents: 6.82% (3.07% + 3.75%) - Pittsburgh residents: 6.07% (3.07% + 3%)

Example

What Pennsylvania Side Hustlers Owe

Let's say you're a single filer in Philadelphia with a $45,000 W-2 job and $10,000 in side hustle income from selling handmade goods, with $1,000 in expenses.

**Your estimated taxes on the side hustle:** - Net self-employment income: $9,000 - Federal SE tax (15.3% of 92.35%): ~$1,273 - Federal income tax on side income: ~$1,980 (22% bracket) - PA State tax (3.07%): ~$276 - Philadelphia EIT (3.75%): ~$338 - **Total additional tax: ~$3,867**

Outside Philadelphia/Pittsburgh, your local tax would be much lower, potentially saving you $200-$300.

Common Deductions for Pennsylvania Freelancers

Pennsylvania freelancers can claim most federal business expense deductions to reduce both state and local taxes. **Home office expenses**: Deductible for dedicated business space; use simplified ($5/sq ft) or actual expense method. **Business-related travel**: Mileage (67 cents/mile for 2025), parking, tolls, and transportation to client sites are deductible. **Equipment and supplies**: Computers, software, office furniture, and tools qualify; Section 179 allows immediate expensing. **Professional services**: Accounting, legal, bookkeeping, and tax preparation fees are fully deductible. **Phone and internet**: Claim the business-use percentage of your monthly bills. **Health insurance premiums**: Self-employed individuals can deduct 100% of premiums. **Retirement contributions**: SEP-IRAs and Solo 401(k)s reduce both federal and Pennsylvania taxable income. Important: Pennsylvania has unique tax rules that differ from federal treatment. PA does not allow the same standard deduction as federal—it uses its own calculation. Some federal deductions don't apply to PA, so consult PA Department of Revenue guidelines for specifics on items like bonus depreciation and Section 179 limits.

Common Questions

Pennsylvania Side Hustle Tax FAQ

Does Pennsylvania have a flat tax on side hustle income?

Yes, Pennsylvania has a flat 3.07% income tax rate on all taxable income including self-employment earnings. However, you may also owe local Earned Income Tax (EIT) of 0.5-3.75% depending on your municipality.

Do I pay local taxes on my side hustle in PA?

Yes, most Pennsylvania municipalities levy an Earned Income Tax (EIT) on net profits from self-employment. Philadelphia is 3.75%, Pittsburgh is 3%, and other areas range from 0.5% to over 3%.

How do I pay PA estimated taxes on my side hustle?

Use Form PA-40 ES to make quarterly estimated payments to Pennsylvania. You'll also need to make separate payments to your local tax collector for the EIT portion.

Do I need to register my side hustle business in Pennsylvania?

Sole proprietors using their legal name don't need to register with the state, but using a fictitious business name requires filing with your county's Prothonotary office. LLCs and corporations must register with the PA Department of State. You may also need local business licenses depending on your municipality.

How do I file local EIT taxes in Pennsylvania?

Local EIT is collected by designated tax collectors, not the state. Find your local tax collector at dced.pa.gov. You'll typically file quarterly or annually depending on your municipality's requirements. Philadelphia uses a different system—file with the Philadelphia Department of Revenue.

Can I deduct SEP-IRA contributions on Pennsylvania taxes?

Yes, Pennsylvania allows deductions for SEP-IRA contributions. These reduce both your federal and PA taxable income, and also reduce local EIT since it's based on net profits. This makes retirement contributions especially valuable for PA side hustlers facing high combined state and local rates.
