Massachusetts runs on brainpower. Anchored by Harvard, MIT, and dozens of other universities, the state is a global center of the life-sciences and biotech industry (Cambridge's Kendall Square) and a powerhouse in healthcare, higher education, technology, robotics, and financial services (Fidelity and State Street). It is one of the most innovation-dense and highest-income economies in the country.
Massachusetts levies a flat individual income tax of 5% on most income. Its signature feature is the voter-approved 'millionaire's tax,' a 4% surtax on annual income above roughly $1.1 million (the threshold indexes for inflation, about $1,108,000 for 2026, confirm the current figure), making the top marginal rate 9%. The state sales tax is 6.25% with no local sales taxes. Short-term capital gains are taxed at a higher rate than the general 5% (confirm current rates). Pass-through profits flow to owners' returns, while C-corporations pay the Massachusetts corporate excise.
Seven core services designed for small businesses across every industry in Massachusetts — all delivered remotely, all handled by our team.
Your most important foundation. We categorize every transaction, reconcile your accounts, and deliver clean P&L and balance sheet reports every single month — so you always know exactly where your business stands.
Months or years behind? We clean it all up — systematically organizing your past transactions so you can get current and stay compliant.
Starting fresh or inheriting a mess? We connect all your accounts, configure your chart of accounts, and set everything up correctly from day one.
Every account, every month. We match your books to your bank statements and flag any discrepancies before they become problems.
P&L, balance sheets, and cash flow statements delivered monthly in a format you can actually read and act on.
We track what you owe and what's owed to you — keeping your cash flow picture clear and your vendor relationships clean.
We ensure your payroll expenses hit your books correctly every pay period — including local Massachusetts municipal withholding — working alongside your payroll processor to keep everything reconciled.

No hourly billing surprises. You pay one flat rate each month based on your transaction volume — and you always know exactly what you're getting.
We don't just hand you a spreadsheet. We deliver clean, readable financial reports each month with plain-language summaries so you can make decisions — not just file paperwork.

We earn your business every month. There are no lock-in agreements — just great service that makes you want to stay. Cancel anytime if it's not working.
