Closing Date Prorations in Massachusetts
In Massachusetts, closing date prorations for real estate taxes are governed by M.G.L. c. 59 and c. 60, and the statutory tax rate is 14% as confirmed by the City of Boston’s official source. This rate applies to the assessed value of the property, and prorations allocate tax liability between buyer and seller based on the number of days each party holds ownership during the tax period. The calculation is performed by the closing attorney or software, using the daily tax amount derived from the annual levy. The official source at https://www.boston.gov/departments/assessing/how-we-tax-your-property provides the exact rate and methodology. A worked example below demonstrates the proration steps.
