Why TaxMaster

Helping New Yorkers Manage Their Taxes for Over 75 Years

Since 1950, TaxMaster has done one thing differently. What started as a family tax practice in Queens, back when a handwritten ledger was still how most small businesses kept their books, is now three-quarters of a century old, but the idea hasn't changed: know your file well enough to actually help, and still be here next year to do it again.

Today that means a small team working out of two offices, building relationships with clients that often last decades. It is more personal than an app, and it is one reason clients stay with us for years.
