Bookkeeping and accounting services for Boston businesses

Massachusetts corporations pay a corporate excise with two components computed on the same return, not one or the other. The income measure is 8% of net income allocated to Massachusetts. The non-income measure is $2.60 per $1,000 of either taxable tangible property or net worth, whichever the corporation's structure requires it to use. Every corporation subject to the excise owes at least the statutory minimum of $456, even a company with no income and no net worth to speak of, so a shell entity or a pre-revenue subsidiary still files and still pays. On the personal side, Massachusetts taxes most income, wages, interest, dividends, and long-term capital gains, at a flat 5%. Short-term capital gains and gains on collectibles are taxed separately at a higher rate under the state's differentiated capital gains schedule. Since the Fair Share Amendment took effect for tax year 2023, income above an annually adjusted threshold, roughly $1 million and indexed for inflation each year, carries an additional 4% surtax on top of the 5% rate, which matters directly to founders and partners taking large distributions or exercising options in a liquidity event. Sales tax sits at a flat 6.25% statewide, with no local option layered on top, so a Boston retailer or restaurant charges the same rate as a business in Worcester or on the Cape. None of this touches federal income tax, which still applies in full on top of every state figure here.

The Massachusetts corporate excise return is due on the 15th day of the third month after the close of the corporation's tax year for most calendar-year C corporations, generally March 15, with the standard six-month extension available on request through MassTaxConnect. S corporations and partnerships file on their own schedules tied to the federal deadlines they mirror. A new corporation or LLC registers with the Secretary of the Commonwealth's Corporations Division before it registers with the Department of Revenue for a Massachusetts tax identification number and, separately, for sales tax and employer withholding accounts through MassTaxConnect. A business selling taxable goods or services needs a Massachusetts Sales and Use Tax Registration before its first sale, and most Boston-area businesses with employees also register for Massachusetts Unemployment Insurance through the Department of Unemployment Assistance and for Paid Family and Medical Leave contributions through the Department of Family and Medical Leave, which reviews its contribution rate and split between employer and employee shares annually. None of this is filed by Finbryn directly. Tax work is prepared by our team and filed by the taxpayer or a licensed tax agent, and registrations are prepared for your signature rather than submitted in our name. We track which registration a specific structure triggers, since a biotech spinout licensing university IP has different obligations at formation than a retail LLC opening its first storefront.

Boston's economy runs on a small number of dense clusters, and each one changes what a set of books needs to track. Biotech and life sciences companies in Kendall Square, the Longwood Medical Area, and along Route 128 carry pre-revenue burn rates, grant and NIH award accounting that has to satisfy funder reporting rules separate from GAAP, R&D expenditures that feed the federal R&D tax credit, and multi-year runway numbers a board or a Series B investor will scrutinize line by line. Companies spinning out of MIT, Harvard, Boston University, and the teaching hospitals carry founder equity structures, university licensing royalties, and sponsored-research agreements that a generic startup bookkeeper tends to miss on first pass. SaaS and enterprise software companies clustered downtown, in the Seaport, and along the Route 128 corridor need deferred revenue tracked to the dollar and a chart of accounts that survives a fundraise or an acquisition without a rebuild. Professional services firms, law firms, asset managers, and consultancies headquartered in the Financial District and the Back Bay run on partner draws, trust accounting for client funds, and utilization reporting rather than product revenue. Healthcare and medical practices across the metro, from Longwood specialty groups to suburban dental and medical offices, need patient billing reconciled against insurance receivables on a completely different rhythm than a subscription business. We build the chart of accounts and month-end process around which of these a Boston business actually is.

Finbryn's delivery team works Eastern time hours that overlap the entire Boston business day, so calls, board-deck questions, and month-end sign-off happen while your team and your investors are both awake, not queued for the next morning. Documents move through a secure client portal and bank-grade connections to QuickBooks Online, Xero, or NetSuite rather than email attachments, and receipts route through Dext or Hubdoc so nothing sits unsorted in a shared drive folder. Same-day turnaround in your time zone means a burn-rate question raised before a Tuesday board call gets answered before that call, not after it. Remote service for Boston businesses, contracted in the United States: no local office, no local staff, and we never imply otherwise. What you get instead is a named point of contact who knows your cap table and your grant reporting requirements, backed by a senior reviewer who checks every close before it reaches you. For a biotech company on a fundraising clock or a services firm closing a busy quarter, that overlap in working hours is often what keeps a diligence request from turning into a week of scrambling.

Boston's biotech and life sciences companies lean on QuickBooks Online early and move to NetSuite or Sage Intacct once grant tracking, multi-entity structures, or inventory for a lab or manufacturing arm outgrow a single ledger. SaaS and software companies run QuickBooks Online or Xero for the books, Stripe or Chargebee for billing, Ramp or Brex for card spend, and Gusto, Rippling, or Justworks for payroll. Professional services firms in the Financial District commonly run QuickBooks Online alongside practice-management software for time and billing, with trust accounting handled in a separate ledger where client funds require it. Banking for the venture-backed set has diversified since the 2023 regional banking disruption, with Mercury, First Republic's successor relationships, and traditional Boston-area banks like Eastern Bank and Rockland Trust all common depending on company stage and founder preference. We work inside whatever stack a business already has and set one up cleanly if there is nothing in place yet, rather than pushing a switch that costs more in migration time than it saves.

Pricing depends on transaction volume, entity count, and which services a business needs beyond monthly bookkeeping, whether that is corporate excise preparation, R&D credit documentation, grant fund tracking, payroll support, or fractional CFO work layered on top. A pre-revenue biotech company with a handful of grant-funded transactions a month sits at a different tier than a multi-location professional services firm running partner draws and trust accounting across several bank accounts. See the rate card for current pricing tiers and what each tier includes. Terms, onboarding scope, and any add-on services are set out in your engagement letter once we have looked at your books and your current stack, and pricing never depends on where our delivery team happens to sit.

A Boston business weighing an in-house bookkeeper against outsourcing is weighing a competitive Massachusetts salary market against a narrower scope of coverage. The U.S. Bureau of Labor Statistics reports a national median annual wage of $50,670 for bookkeeping, accounting, and auditing clerks as of May 2025, and Boston's cost of living together with the labor market pull from finance, biotech, and higher education tends to push a local hire well above that national median once benefits and payroll taxes are added on top of base pay. That figure buys one person, at one skill level, working the hours they work. An outsourced team spreads bookkeeping, tax preparation, R&D credit tracking, payroll support, and CFO-level review across a group with senior oversight built in, without the cost of a full-time hire competing for the same limited pool of accounting talent that every biotech and SaaS company in the metro is also trying to hire from. For a company that does not yet need a full-time controller five days a week, that math tends to favor outsourcing until transaction volume or grant-reporting complexity genuinely justifies an in-house seat.

We start with a short call to understand your entity structure, current software, and where your books stand today, whether that is clean and current or months behind. From there we scope which services you need, whether that is monthly bookkeeping alone or bookkeeping plus corporate excise preparation, R&D credit documentation, and grant fund tracking, and give you a proposal with pricing tied to your actual transaction volume. Once you sign on, we set up secure access to your bank feeds and software, connect Dext or Hubdoc for receipt capture, and if there is a backlog, we run catch-up bookkeeping to bring your books current before moving to a normal monthly cycle timed to your board or investor reporting calendar. No commitment is required before that first call, and you keep ownership of your books and your software logins from day one.
