OVERVIEW
California and Connecticut produce a genuine crossover, not a one-sided winner: California's steep 10-bracket system (1% to 13.3%) is actually cheaper than Connecticut's progressive 2-6.99% tax below about $103,000 of income, but Connecticut pulls ahead once earnings cross above that point. At $100,000, California's $4,911 state tax bill is $64/year lower than Connecticut's $4,975, but the gap swings the other way at higher incomes — Connecticut saves $3,461/year at $250,000 and $9,250/year at $500,000, because California's 9.3%+ brackets apply to almost all taxable income above $75,197 while Connecticut's top rate tops out at 6.99%. Property tax reinforces Connecticut's disadvantage though: its average effective rate of roughly 1.54% is more than double California's roughly 0.70% (itself capped by Proposition 13), which claws back a meaningful chunk of Connecticut's income-tax edge for homeowners.

California Pros & Cons

+ PROS
  • Actually cheaper than Connecticut for anyone earning below roughly $103,000 — California's 1-8% brackets tax lower-middle income lightly
  • Proposition 13 caps property tax increases, keeping the average effective rate (~0.70%) well below Connecticut's ~1.54%
  • Social Security is fully exempt from state tax
  • By far the largest, highest-paying job market of the two states — tech, entertainment, and biotech salaries routinely outpace Connecticut's
− CONS
  • The 9.3% bracket starts at just $75,197 of taxable income, so nearly all six-figure income is taxed at 9.3% or more — costing $1,336 to $9,250/year more than Connecticut at $150,000 to $500,000 (above roughly $103,000)
  • No blanket exemption for pensions, 401(k), or IRA withdrawals — taxed at California's steep ordinary rates with no retirement-specific relief
  • Home prices are generally much higher than Connecticut's, so even the lower property tax rate applies to a far larger tax base
  • Highest state income tax in the nation at the top end — the 13.3% top rate applies above $1,000,000
⚓

Connecticut Pros & Cons

+ PROS
  • Cheaper than California at every income level above roughly $103,000, saving $1,336 to $9,250/year at $150,000 to $500,000
  • Social Security is fully exempt below $75,000 AGI (single) or $100,000 (married); only 25% of benefits become taxable above that threshold
  • Connecticut phased in a full pension and annuity income exemption below the same $75,000/$100,000 AGI thresholds, completed by 2026
  • NYC-commuter haven with a lower top rate than New York's 10.9%, while still offering access to the same metro job market
− CONS
  • More expensive than California for anyone earning under about $103,000, since Connecticut's brackets ramp up quickly on modest incomes
  • Average effective property tax rate of roughly 1.54% is more than double California's ~0.70%
  • No blanket exemption for private pension or 401(k)/IRA income above the AGI thresholds — taxed at Connecticut's regular 2-6.99% rates
  • High cost of living in Fairfield County (NYC suburbs) partially offsets the income-tax advantage at higher incomes
FAQ

Frequently Asked Questions

Is California or Connecticut cheaper for state income tax?

It depends on income. Below about $103,000, California is actually cheaper because its bottom brackets (1-8%) tax modest incomes lightly: at $100,000, California's $4,911 beats Connecticut's $4,975 by $64/year. Above that, Connecticut pulls ahead, by $3,461/year at $250,000 and $9,250/year at $500,000, since California's 9.3%+ brackets apply to almost all six-figure income while Connecticut's top rate caps at 6.99%.

Where exactly does the crossover happen between California and Connecticut?

The two states are in near-perfect tax parity at approximately $103,000 of income. Below that point California's lower starting brackets (1%, 2%, 4%, 6%, 8%) keep its bill smaller; above it, California's 9.3% bracket (which starts at $75,197 of taxable income) overtakes Connecticut's 5.5%-6% brackets, and Connecticut's edge widens from there.

Which state has lower property tax, California or Connecticut?

California has the clearly lower average effective property tax rate at roughly 0.70% (capped by Proposition 13), compared to Connecticut's roughly 1.54%. On a $400,000 home, that's about $2,800/year in California versus $6,160/year in Connecticut, a savings of about $3,360/year that partially offsets Connecticut's income-tax advantage at higher incomes.

Does either state tax Social Security or retirement income?

Both states fully exempt Social Security below certain thresholds — California exempts it entirely, while Connecticut exempts it fully below $75,000 AGI (single) or $100,000 (married), taxing only 25% of benefits above that. Connecticut also phased in a full pension and annuity exemption below those same thresholds, completed by 2026. California has no such pension exemption — it taxes all other retirement income (pensions, 401(k), IRA withdrawals) at its full progressive rates up to 13.3%.

How much would I save moving from California to Connecticut?

It depends on your income. At $50,000, moving from California to Connecticut would actually cost you about $827/year more in state income tax. At $100,000, it would still cost you about $64/year more. At $250,000, you'd save about $3,461/year, and at $500,000 the savings reach roughly $9,250/year — though Connecticut's much higher property tax offsets some of that gain for homeowners.

So which state wins on combined income plus property tax at $100,000?

California wins. At $100,000 income with a $400,000 home, California already has the lower income tax (by about $64/year) and the lower property tax (about $3,360/year less than Connecticut on the same home), so California comes out ahead overall for homeowners at this income level.

Does either state charge a local or city income tax?

No. Neither California nor Connecticut allows cities or counties to levy a general local income tax, so the state's bracket structure is the whole income-tax picture in both cases.

How do capital gains taxes compare between California and Connecticut?

Neither state gives capital gains a preferential rate — both tax gains as ordinary income. California's rate can reach 13.3% on large gains, while Connecticut's tops out at 6.99%, making Connecticut meaningfully cheaper for investors with substantial realized gains, on top of its ordinary-income advantage above roughly $103,000.
