A strong technology sector has grown up alongside it, and law firms and agencies fill out Boston's professional services base. Massachusetts keeps sales tax simple with a flat 6.25% rate and no local add-ons anywhere in the state, unlike neighbors that stack city and county taxes on top. Income tax is mostly a flat rate too, but a surtax on income above one million dollars adds a layer that higher-earning owners and partners need tracked carefully. Eastern Time (ET). Our US team works 8am to 8pm ET, covering the entire Massachusetts business day live. ## Massachusetts tax and compliance notes ### Flat statewide sales tax Massachusetts charges a flat 6.25% sales tax with no local city or county add-ons anywhere in the state, which simplifies rate tracking compared to states with layered local rates. ### Flat income tax plus a millionaire's surtax Massachusetts personal income tax is a flat 5%, but an additional 4% surtax applies to income above one million dollars, sometimes called the millionaire's tax. Owners and partners near that threshold need income tracked carefully across the year. ### Corporate excise tax Massachusetts corporations pay a corporate excise tax made up of an income component and a smaller tangible property or net worth component, whichever calculation applies. Bookkeeping needs both net income and asset figures kept current. General notes, not advice. Filing is done by you, your CPA, accountant or registered agent; we prepare the workings. ## Industries we serve in Massachusetts - **[SaaS and technology](https://ledgerbpo.com/industries/saas/)** Boston and Cambridge's technology cluster needs subscription revenue and deferred revenue matched cleanly against billing platforms. - **[Medical practices](https://ledgerbpo.com/industries/medical-practices/)** Leading hospital systems around Boston support a dense base of medical practices needing patient billing reconciled against insurance. - **[Clinical labs](https://ledgerbpo.com/industries/clinical-labs/)** Cambridge's biotech and life sciences cluster needs lab billing reconciled against insurance and research grant funding. - **[Law firms](https://ledgerbpo.com/industries/law-firms/)** Boston's concentrated legal market needs trust accounting kept strictly separate from firm operating funds. - **[Agencies](https://ledgerbpo.com/industries/agencies/)** Boston's marketing and consulting agency base needs project invoicing reconciled against client retainers. ## Software Massachusetts businesses use - [QuickBooks Online](https://ledgerbpo.com/software/quickbooks-online/) - [Xero](https://ledgerbpo.com/software/xero/) - [NetSuite](https://ledgerbpo.com/software/netsuite/) - [Gusto](https://ledgerbpo.com/software/gusto/) - [Bill.com](https://ledgerbpo.com/software/bill-com/) - [All 50 platforms](https://ledgerbpo.com/software/) ## Services for Massachusetts businesses - [Bookkeeping](https://ledgerbpo.com/services/bookkeeping/) - [Invoicing and billing](https://ledgerbpo.com/services/invoicing-and-billing/) - [Accounts receivable](https://ledgerbpo.com/services/accounts-receivable/) - [Accounts payable](https://ledgerbpo.com/services/accounts-payable/) - [Bank reconciliation](https://ledgerbpo.com/services/bank-reconciliation/) - [Month end close](https://ledgerbpo.com/services/month-end-close/) - [All 84 services](https://ledgerbpo.com/services/) ## Frequently asked questions ### Do you have an office in Massachusetts?
