Data Scientist Salary in Pennsylvania: Median $90,700 in 2026
Pennsylvania (PA) · State tax: 3.1% top marginal · RPP 97.4 · Rank #15 of 51 for take-home
A Data Scientist in Pennsylvania earns a median of $90,700 per year, based on the most recent 2023 BLS Occupational Employment and Wage Statistics release[1]adjusted for Pennsylvania's Bureau of Economic Analysis Regional Price Parity of 97.4 (US = 100)[2]. The 10th percentile starts at about $48,370, while the 90th percentile reaches $156,160. After federal income tax, FICA, and Pennsylvania state income tax, a single-filer takes home roughly $69,575/year — about $5,798/month or $2,676 every other week.
Because Pennsylvania is a mid-cost state (RPP 97.4), the real purchasing power of that take-home is roughly $71,432 in national-average terms. Among all 51 jurisdictions in the US, Pennsylvania ranks #15 for take-home pay on a $90,700 gross — a Data Scientist keeps 76.7% of every dollar earned after federal, state, and payroll taxes. Nationally, BLS projects 36% growth in this occupation through 2034[3], which typically translates into comparable demand at the Pennsylvania state level.

How Data Scientist Salaries Work in Pennsylvania
A Data Scientist paycheck in Pennsylvania is stacked the same way as every US paycheck: gross wage, then federal income tax withholding based on IRS Publication 17 bracket tables[4], then FICA — Social Security 6.2% (up to the 2025 wage base of $176,100) and Medicare 1.45% (plus 0.9% above $200,000)[5], then whatever the state layers on top. Pennsylvania applies a flat income tax with a top marginal rate of 3.1%; on a $90,700 median Data Scientist salary the effective rate comes out to 3.1%, or $2,784 per year.[6]
Beyond income tax, two Pennsylvania floors matter. State minimum wage sets the price of entry-level labor and pulls up the bottom of the wage distribution[7]. Cost of living — measured by the BEA Regional Price Parity of 97.4 — sets the price of housing, groceries, utilities, and services that determine how far the paycheck goes[2]. Together these two numbers explain most of the variance between nominal and real Data Scientist compensation across states.
Local demand also matters. State-level OEWS puts about 166,830 people in this SOC group across Pennsylvania, which lets employers compete on wages rather than benefits alone.The near-average RPP keeps nominal wages close to the US median for comparable roles. Two workers with identical Data Scientist titles can therefore see very different take-home outcomes depending purely on Pennsylvania's tax and cost profile.
The complete identity: take_home = gross − federal_tax − state_tax − FICA − pre_tax_deductions. Every number in the table above, and every paycheck calculator on CalcFi, runs that identity client-side. No inputs leave your browser.

Same $90,700 gross salary, different state tax regimes. The table shows what a single-filer Data Scientistwould net in each bordering state. Useful if you're comparing job offers across state lines or considering a relocation.
| State | State tax (eff.) | Annual take-home | vs PA |
|---|---|---|---|
| Pennsylvania ★ | 3.1% | $69,575 | — |
| Delaware | 5.2% | $67,604 | -$1,971 |

★ = no state individual income tax. Numbers assume identical $$90,700 gross, single filer, standard deduction. Real-world comparisons should also factor in cost-of-living differences (RPP) and any local income taxes[6][2].
Cost of Living vs Salary — Purchasing Power in Pennsylvania
Nominal dollars only tell part of the story. The BEA Regional Price Parity for Pennsylvania is 97.4 (US = 100)[2]. That means an identical basket of goods and services costs 2.6% less in Pennsylvania than in an average-cost US location. A Data Scientist's $69,575 nominal take-home therefore equals about $71,432 of national-average purchasing power.
Concretely, that shows up in three budget buckets:
- Housing. The single biggest driver. At a near-national RPP, expect housing to run 25–32% of take-home for a median Data Scientist salary.
- Groceries + services.BEA publishes sub-indexes for goods, rents, and other services. Goods tend to be closer to national averages (they're traded); services and rents are where the big state-level spreads show up.
- State + local tax. Pennsylvania's state income tax removes 3.1% of gross before it ever hits the RPP basket — so comparing pure RPP between states with very different tax structures understates the true cost difference.
The classic rule of thumb — "aim for take-home ≥ 3x your monthly housing cost" — holds in Pennsylvania only above the 60th-percentile wage band for this occupation. Below that threshold, the RPP hit compounds with fixed housing costs and the real savings rate collapses. Above it, Pennsylvania's lower cost base makes this a reasonable wealth-building state for Data Scientists.
Where Data Scientists Work in Pennsylvania
BLS OEWS attributes roughly 166,830 Pennsylvania workers to the Technology major group containing Data Scientist.Major hiring industries for Data Scientists tend to cluster into three groups: (1) large private employers in technology (primary source of wage pressure at the top of the distribution); (2) state and local government — consistently one of the top five technology employers in most US states; and (3) federal government and contractors — especially relevant in states with large DoD or federal civilian footprints.
Typical entry requirement for this role is a master's degree. Common tax-deductible professional expenses that Data Scientists in Pennsylvania can consider — where itemizing makes sense — include: Professional development (conferences, courses), Computer equipment & software, Home office deduction, Technical books and journals. Confirm deductibility with a CPA; 2017 TCJA changes limited unreimbursed employee expenses, but self-employed or contractor Data Scientists still get full Schedule C treatment.
Career Progression & Related Professions in Pennsylvania
Early-career Data Scientists in Pennsylvania typically start near the 10th percentile ($48,370), reach the median ($90,700) after 4–8 years, and enter the 90th percentile ($156,160) with senior or specialized roles. Related technology occupations in Pennsylvania:

Income and tax climate. Median household income in Pennsylvania reaches $80,060 per the ACS five-year vintage, pulling above the $78,538 U.S. median. Pennsylvania's top marginal state income tax bracket lands at 3.07% — compared to the volume-weighted national average around 4-5%. BEA's Regional Price Parity scores Pennsylvania at 100.0 (national = 100), meaning a dollar in Pennsylvania buys 100¢ — more goods and services than the same dollar nationally.
How Pennsylvania affects take-home pay. Federal FICA, Medicare, and income tax are identical for every wage earner regardless of state. Pennsylvania's contribution is the state income tax overlay plus any state-level disability or paid-family-leave deductions. Where applicable, the calculator factors in the local minimum wage when an hourly-to-salary conversion is involved, and uses BLS OEWS median earnings for Pennsylvania as the contextual baseline shown alongside your inputs.

Methodology — How we compute this page
Wage percentiles. Primary source is the BLS Occupational Employment and Wage Statistics (OEWS) state-level release, 2023 vintage. We pull the state row for the SOC major group that contains Data Scientist (15-0000). When the BLS suppresses a cell for data-quality reasons, we fall back to the national percentile scaled by Pennsylvania's BEA RPP — the same method BLS's own reports use.
Take-home tax math. Federal tax uses 2025 IRS brackets and the single standard deduction ($15,000). State tax uses the Pennsylvania2026 brackets from the state Department of Revenue, mirrored by Tax Foundation where the DoR's PDF is paywalled or split across multiple publications. FICA is Social Security 6.2% (capped at $176,100 wage base) + Medicare 1.45% + 0.9% Additional Medicare above $200,000. All math is the deterministic identity take_home = gross − federal − state − FICA; no Monte Carlo or estimator models.
Cost-of-living adjustments.We use BEA's Regional Price Parities (RPP) for all-items. RPP is a purchasing-power index where US = 100. Real (COL-adjusted) take-home is nominal_take_home / (RPP / 100). City-level estimates scale the statewide OEWS median by each metro's composite COL index from our /data/cities.ts dataset, which merges Census ACS, BLS, and Zillow inputs.
Refresh cadence. BLS OEWS releases once a year (typically March, for the prior May reference period). BEA RPP releases once a year in December. Federal tax brackets are updated annually by the IRS (October inflation adjustment). State brackets refresh per legislative calendar. The dateModified shown above auto-bumps when any sourced value's retrievedAt changes — no template edit required.
Known limits.Statewide medians mask large intra-state variance — metros and rural counties can differ by 20–40% for the same SOC code. We don't currently bake in local income taxes (e.g. NYC, Portland-OR supplemental). We assume single-filer, standard deduction, no pre-tax contributions; users with itemized deductions or 401(k) deferrals should plug their specifics into the linked calculators. Suppressed BLS cells fall through to national-scaled fallbacks, which can under-estimate demand in specialty states.
