FAQ

Frequently Asked Questions

How much will I save moving from California to Massachusetts?

At $100,000 income, Massachusetts saves $231/year (CA ~4.9% effective vs MA ~4.7% effective on a 5% flat rate). At $500,000: MA saves $19,020/year. Earners below about $93k pay more in MA because of its flat 5% rate. For expensive homeowners ($1M+), CA's Prop 13 low property tax (0.73%) partially offsets MA's income tax advantage. Overall, the state income tax gap widens sharply with income — from a slim $231/year at $100k to $19,020/year at $500k — as MA's flat rate increasingly undercuts CA's climbing top brackets.

Which state is better for tech workers?

California wins on salary: Silicon Valley pays $250k-$500k+ total comp (highest in world) with massive stock options. However, Massachusetts offers lower income tax (5% vs CA 9.3-13.3%), saves $231-$52,779/year (at $1,000,000). Boston's biotech hub (Kendall Square) is world's #1. Choose CA for career maximization, MA for better tax treatment and work-life balance.

What about cost of living?

Nearly identical overall (CA 151.7 vs MA 149.7). Housing: SF $1.5M median vs Boston $825k (CA 82% more expensive). However, both are among most expensive states in US. Boston rent 33% cheaper than SF ($2,800 vs $4,200 for 1BR). Transportation: MA 21% lower (better public transit). Choose based on lifestyle, not cost of living.

Which state has better quality of life?

California: Year-round sunshine, beaches, mountains, perfect weather. Massachusetts: Four seasons, fall foliage, near-universal health coverage, walkable cities, proximity to Europe. Both have world-class universities. CA better for weather, MA better for education/healthcare. It's lifestyle preference more than taxes.
