How to Lower Your Boston Taxes?
Strategic ways to reduce your liability and grow your net wealth.
Claim Rent Paid
Ensure you are claiming the maximum 50% rental deduction ($4,000 limit) to lower your state taxable income.
Commuter Deduction
Keep your receipts for MBTA passes and EZ-Pass tolls; they can be deducted once they exceed $150 per year.
Maximize 401(k)
Pre-tax contributions reduce your Adjusted Gross Income (AGI), which automatically lowers your MA taxable base.
MEFA 529 Deduction
MA residents can deduct up to $1,000 (single) or $2,000 (joint) for contributions to the state-sponsored college plan.
HSA Contributions
Massachusetts recognizes the tax-exempt status of HSAs. Contributions reduce your state taxable income dollar-for-dollar.
Charity Deductions
Massachusetts has restored the charitable deduction; ensure you report your donations to lower your state liability.
Social Security Benefit
Good news: Massachusetts does not tax Social Security benefits. Plan your retirement distributions accordingly.
