How to read San Diego vs San Francisco
Both columns use the same $100,000 single-filer vignette for 2026: federal + state income tax (+ NYC city tax when modeled) + employee FICA + state SDI/PFML when applicable.
San Diego and San Francisco model identical take-home because they share California rules. COL indexes (146 vs 165) are the practical differentiator for purchasing power.
Same-state pairs should match take-home on this hub; COL is the day-to-day differentiator.
What drives US metro paycheck gaps
Employees are taxed by state of residence (and sometimes city) for wage income — federal brackets apply nationwide. NYC is the only metro on this hub with a separately modeled city PIT.
San Diego models about $5,086 state tax and $7,650 FICA. San Francisco models about $5,086 and $7,650 FICA.
Same-state pairs (e.g. San Francisco–Los Angeles) should match take-home; no-PIT corridors (Austin–Miami) also tie. Cross-state corridors (NYC–Austin, SF–Seattle) are where bracket and payroll differences appear.
Why the income ladder matters
At $50k the modeled gap between these metros is about $0; at $200k it is about $0. Bracket thresholds and FICA/SDI ceilings can reorder winners as salary rises.
Use the ladder before accepting an offer at a different gross — a metro that wins at $100k may not win at $150k or $200k.

Cost of living vs take-home
San Diego COL index 146 · COL-adjusted proxy $49,859. San Francisco COL index 165 · proxy $44,117.
COL-adjusted take-home is a purchasing-power hint from relocation indexes — not IRS withholding and not a substitute for rent quotes or a budget.
A higher take-home metro can still feel tighter if housing dominates; pair this compare with the relocation salary calculator.
Limitations of this compare
Single filer, standard deduction, no 401(k), no dependents, no stock options, no remote multi-state income sourcing.
Only NYC city PIT is modeled as a separate local line; other city wage taxes are disclosed when known.

Decision guides
Same-state move
Focus on rent, commute, and COL (146 vs 165) — income tax will not move the needle between San Diego and SF on this model.
Job offer negotiation
Ask for the work state (and city residency rules) on the contract. A CA vs CA posting can change take-home more than the skyline name.
High COL destination
If relocating to the higher-COL metro (SF), stress-test rent against take-home — tax wins do not automatically fund housing.
What this compare excludes
- 401(k), IRA, HSA, and other pre-tax deferrals
- Dependents, credits, and itemized deductions beyond the standard single-filer stack
- RSUs, ISOs, ESPP, and other stock compensation
- Remote workers with multi-state income sourcing
- Unmodeled local wage taxes (Philadelphia Wage Tax, Detroit city PIT, Ohio municipal, Pittsburgh EIT/LST)
- Employer benefits, union dues, and commuting subsidies
Myths vs reality
“Every big city has a NYC-style city income tax.”
San Diego and SF do not add modeled city PIT. Gaps come from state tax and payroll.
“Moving from San Diego to SF changes my income tax.”
Both are in California — modeled take-home matches. Housing and COL (146 vs 165) change; the state return does not.
“Texas and Florida take-home always matches Washington.”
Washington has no wage PIT, but employee PFML can trim take-home below the TX/FL/NV cluster — check the SDI/PFML line on the scoreboard.
“COL-adjusted take-home is my real paycheck.”
It is a purchasing-power proxy only. Tax returns care about taxable wages and credits — not our relocation COL index.
