Massachusetts Financial Snapshot (2026) — Retirement Savings Calculator
Social Security + 401(k) state treatment + estate exemption shape the retirement savings calculator in Massachusetts. Every row cites a primary public dataset. Numbers reflect the most recent vintage available; refresh cadence is documented in the methodology.
How the Retirement Savings Calculator Math Works Under Massachusetts Law
Your retirement projection in Massachusettshas two tax-aware legs: the accumulation side (contributions reduce today's AGI) and the withdrawal side (distributions are taxed when you pull them out). Massachusetts does NOT tax Social Security benefits, and 401(k) withdrawals ARE subject to state income tax in full[1].
This changes the math. A flat-tax state that spares Social Security means the 4% safe-withdrawal rule stretches further in real terms than the raw headline number suggests — the right portfolio target is FIRE_number = annual_expenses × 25, where annual_expenses already nets out state taxes. Estate planning adds a third leg: Massachusetts's state estate tax exemption is $2,000,000 — below the federal $13.99M threshold, so larger estates plan differently here.
Calc-specific note: Rule of 25: FIRE number = annual expenses × 25. Expenses must be net of state taxes on withdrawals.
Worked example — Massachusetts
A Massachusetts household targeting $80,000/year in retirement spending needs a portfolio ≈ $2,000,000 (25× rule, 4% SWR). With 9.00% state tax on withdrawals, that target rises to ≈ $2,197,802 net.
