Porter Square is one of Cambridge's distinctive business communities. A retail and small-business neighborhood. Whether you run a storefront, a service company, or a home-based venture here, Tides Bookkeeping keeps your books accurate, categorized, and ready for tax season - without you ever leaving Porter Square.
As part of the greater Cambridge, MA economy within Middlesex County, Porter Square businesses share the same Massachusetts tax and compliance landscape as the rest of the area. Our remote-first process means you get a dedicated bookkeeper and clean monthly financials no matter where in Cambridge you are located - reconciled accounts, categorized transactions, and monthly profit-and-loss and balance-sheet reporting you can actually use.
Massachusetts keeps its taxes flat but not low. A flat 5% state income tax applies to most income, plus a 4% surtax on the portion above roughly $1 million (the voter-approved millionaire's tax), so high earners effectively pay 9% at the top. A flat 6.25% state sales tax applies statewide with no local add-on - one of the simpler sales-tax systems in the country - and corporations owe the state corporate excise. Keeping income, sales, and corporate-excise records clean under the flat system is exactly what we do.
