ZIP Code 01803

ZIP code 01803, near Cambridge, ranks among the more affluent areas, with a median household income of $146,436 and per-capita income of $69,012. Homes here carry a median value of $740,600, and the county-level effective property tax rate of 1.03% means owners pay a meaningful share of that value each year. Add a combined sales tax of 6.25%, and the overall tax load reflects the area's high earning power rather than squeezing a struggling population. Households in this bracket can absorb these costs, though the property tax on a home at this price point still amounts to a substantial annual sum.
