Local income tax (never in the total above): Nearly every Pennsylvania municipality levies an earned income tax on net profits, typically 1% (Philadelphia's net profits tax: 3.74% for residents in 2025, 3.735% in 2026). Local tax is not included here.

Amounts to set aside, not bills: federal $3,701 for each Form 1040-ES installment (Apr 15, Jun 15, Sep 15, Jan 15). Pennsylvania: $553 per installment on its own schedule. For the safe-harbor amount and payments you have already made, use the quarterly calculator with these inputs. Pennsylvania 2026 rates are not yet published; state figures use 2025 rates.

Pennsylvania and self-employment income

Pennsylvania has a flat 3.07% tax on net profits from business. There is no standard deduction and no exemptions, and the state does not allow the federal deduction for half of self-employment tax, so the tax applies to your full net profit.

How the federal part is worked out

Net profit is 1099 income less business expenses (Schedule C). Self-employment tax is 15.3% of 92.35% of that profit — 12.4% Social Security up to $184,500 of combined wages and earnings, 2.9% Medicare on all of it. Half of that tax, the $16,100 standard deduction ($32,200 joint) and the 20% qualified business income deduction come off before the 2026 brackets are applied; the child tax credit and the earned income credit then reduce what is left, and the refundable parts can offset self-employment tax. The methodology page sets out the full sequence and every rule the calculator leaves out, including how Pennsylvania's figures are derived.

Quarterly estimated tax deadlines (2026)

If you expect to owe $1,000 or more of federal tax for the year, the IRS expects four estimated payments (Form 1040-ES). Pennsylvania runs its own estimated-payment schedule with its own threshold (see above); the calculator shows the federal installment and the Pennsylvania installment separately, and one combined amount to set aside each quarter.

The 2026 dates are April 15, 2026, June 15, 2026, September 15, 2026, January 15, 2027. The federal amount is split into four equal Form 1040-ES installments after any withholding you entered; paying 100% of last year's tax instead (110% above $150,000 of prior-year AGI) also avoids the penalty. The quarterly calculator works that out and subtracts what you have already paid, and the guide to the due dates explains the rule.

Common questions

Does Pennsylvania tax self-employment income differently from wages?

For state income tax, net profit from self-employment is ordinary income like wages. The self-employment tax itself is federal only; Pennsylvania does not add a state equivalent.

Is half of self-employment tax really deductible?

Yes, for federal tax. The employer-equivalent half is an adjustment to income on Schedule 1, which lowers your AGI and therefore your federal income tax. It does not reduce the self-employment tax itself. Pennsylvania does not allow this deduction for state tax.

Does an LLC change these numbers?

For federal income tax and self-employment tax, a single-member LLC taxed as a sole proprietorship follows exactly the calculation shown here. State and local obligations can still differ: an LLC may be a taxable entity for a state's franchise, gross-receipts or excise tax, and may owe registration or licence fees a sole proprietor does not — Pennsylvania's are listed above. Electing S-corporation status changes the federal arithmetic too (salary plus distributions) and is outside this tool's scope.

What if I moved to Pennsylvania during the year?

Income earned while you were a resident of another state is taxable there under that state's rules. This calculator assumes all income was earned as a Pennsylvania resident.
