Quick answer

Comparing Colorado and Massachusetts at $100,000 single, take-home favors Colorado by about $1,108 per year. Colorado runs a flat 4.4% state rate plus Colorado FAMLI; Massachusetts runs a flat 5% state rate plus Massachusetts PFML. Both states share a flat-rate structure but at different headline figures.

Colorado and Massachusetts both apply flat-rate state income taxes, putting their structural shape closer together than most cross-region pairs. Colorado levies a 4.4% flat rate, with Colorado FAMLI as a per-paycheck deduction capped on annual wages. Massachusetts levies a 5% flat rate, with Massachusetts PFML on a similar employee-share basis. A separate Massachusetts Millionaire Surtax pushes the all-in top marginal to 9% on income above the state's indexed seven-figure threshold, well above $100,000. Denver and Boulder anchor Colorado's tech and aerospace base: Lockheed Martin operates a major Denver-area campus, Ball Aerospace headquarters in Boulder, and Boulder's outdoor-recreation economy (REI, Patagonia operations, ski resorts in the Front Range) carries a parallel identity. Massachusetts anchors a Boston-area cluster of biotech (Moderna, Vertex, Biogen), financial services (Fidelity, State Street), and the MIT-Harvard university gravity that pulls research and venture capital. At $100,000 single, a Colorado resident takes home $75,048 versus a Massachusetts resident's $73,940, a gap of $1,108 per year.

What this comparison includes

This comparison computes 2026 take-home pay in Colorado and Massachusetts side by side, using 2026 federal brackets after the standard deduction, FICA contributions (Social Security up to the annual wage base, Medicare on all wages, plus the Additional Medicare Tax above the filing-status threshold), and each state's income tax schedule along with any state-administered payroll programs and supported local layers. It excludes employer-side payroll taxes, custom W-4 elections, supplemental-wage handling for bonuses or equity vesting, and income from sources other than W-2 wages. City-level taxes are layered only on the dedicated metro pages; this comparison covers state-and-typical-local figures only, so a worker considering a specific metro should follow the relevant city link in the See also section.

Colorado vs Massachusetts FAQ

How much more is take-home in Colorado than Massachusetts at $100,000?

At $100,000 single, a Colorado resident keeps approximately $1,108 more per year than a Massachusetts resident, or roughly $92 per month. The driver is the 4.4% vs 5% flat-rate gap; both states layer Paid Leave on top but at similar small percentages. Federal income tax and FICA are identical at the same gross salary.

Does the Colorado vs Massachusetts gap scale linearly with salary?

Roughly linearly across the range. Both states use flat-rate structures, so the gap scales in proportion to salary: $798 at $50k single, $1,108 at $100k, $2,025 at $250k. The Massachusetts Millionaire Surtax doesn't bend the curve at any tier shown because it only applies above seven figures.

Does this comparison include local taxes?

No. Colorado has no city or county wage tax outside Denver's small Occupational Privilege Tax (a fixed monthly fee on employees, not a percentage). Massachusetts has no city wage tax of any kind. The state-only numbers shown capture nearly the full state-and-local picture for residents of both states.

How does married filing jointly, head of household, or filing separately change the CO vs MA gap?

Filing jointly drops federal tax through wider MFJ brackets and a doubled standard deduction. Both states use flat rates that are filing-status-neutral across MFJ, HoH, and MFS, so the state-side dollar gap stays close to the rate-times-income shape at this salary. Massachusetts's PFML and Colorado's FAMLI deductions apply per worker across all four statuses. The directional advantage holds at every tier.

What about cost-of-living differences between Colorado and Massachusetts?

Paycheck math is one input; cost-of-living differences often swamp the tax gap. Denver and Boulder housing costs have climbed sharply, narrowing the gap against Boston suburbs, while Greater Boston (Cambridge, Newton, Brookline) carries some of the country's highest housing costs. Treat the take-home delta alongside metro-level housing comps and property tax figures before deciding.

How does CO vs MA compare to other flat-rate cross-region pairs?

If you're considering broader options, Colorado vs New York offers a comparable structural contrast with different metro economies. Massachusetts vs New Hampshire produces a much larger gap because NH taxes no wage income. Both Colorado-anchor and Massachusetts-anchor pairs vary widely in absolute dollar terms depending on the other side's structure.
