Capital gains tax on a rental property applies to the difference between the amount realized on sale and the property's adjusted basis, not to the full sale price. Adjusted basis starts with the original purchase price plus qualifying capital improvements, and it is then reduced, dollar for dollar, by the depreciation deductions the owner claimed, or was entitled to claim, over the holding period. Because depreciation lowers basis every year the property is held, a rental owned for a decade or more frequently produces a much larger taxable gain at sale than the simple difference between the purchase price and the sale price would suggest, since years of depreciation have already been subtracted from that starting basis.
Once the gain is calculated, it is generally split into two pieces for federal tax purposes. The portion attributable to prior depreciation is taxed as unrecaptured Section 1250 gain, subject to a federal rate capped at twenty-five percent, while the remaining gain is taxed at the taxpayer's applicable long-term capital gains rate, generally zero, fifteen, or twenty percent depending on total taxable income for the year. A taxpayer with significant other income in the sale year may also owe the three and eight tenths percent net investment income tax on some or all of the gain, since rental gain is generally treated as investment income for that surtax.
Massachusetts generally follows the federal characterization of long-term versus short-term gain but applies its own rate schedule. Long-term gain on a rental property held more than one year is generally taxed at the Commonwealth's flat rate applicable to most income, while short-term gain on property held one year or less is taxed at a materially higher state rate. Massachusetts also imposes an additional surtax on a taxpayer's total annual income above a high threshold that is adjusted periodically, commonly called the Fair Share surtax, which can apply to a large one-time gain on a Boston, MA rental sale even for an owner whose income in an ordinary year would fall well under that threshold. Because both the surtax threshold and the underlying rates can change from year to year, an owner planning a sale should confirm the current figures with a Massachusetts CPA rather than relying on a number from a prior tax year.
A properly structured Section 1031 exchange does not eliminate this gain, it defers recognition of it. Instead of realizing capital gain and unrecaptured Section 1250 gain in the year of sale, the taxpayer carries the relinquished property's adjusted basis, reduced further by any boot recognized, into the replacement property, and both the capital gains and the depreciation recapture components continue to be deferred until a future taxable sale, unless the taxpayer exchanges again. For a Boston, MA rental owner sitting on substantial depreciation after years of ownership in a market like Dorchester, Jamaica Plain, or the inner suburbs, this deferral often represents the single largest lever available for preserving investable capital, since neither the federal depreciation recapture rate nor the Massachusetts flat rate is actually avoided, only postponed.
Timing matters for how much of the deferral is actually captured. A partial exchange, where the taxpayer receives some cash or reduces debt without offsetting that reduction with new cash, generates boot, and boot is treated as recognized gain up to the amount of gain realized on the sale, drawn first from the depreciation recapture component before reaching the lower-taxed capital gain portion. This ordering rule means even a modest amount of cash boot on a heavily depreciated rental can trigger a disproportionately large current tax bill relative to the dollar amount received, which is a detail that surprises owners who assume boot is taxed pro rata across all of the gain components.
Owners weighing whether to sell a Boston, MA rental outright or exchange into a new property often benefit from running the actual numbers before listing, since the size of the depreciation recapture component, not just the headline capital gain, drives how much tax exposure a straight sale would create. The site's Tax Impact Briefing service models depreciation recapture, Massachusetts addbacks, and boot scenarios side by side so an owner can compare a taxable sale against an exchange with real figures rather than rough estimates.
It is also worth noting that capital gains exposure on a rental is distinct from the exclusion available on a primary residence sale under Section 121. A property used exclusively as a rental, with no period of qualifying owner-occupancy, does not benefit from that exclusion, which is one reason many Boston, MA landlords who have never lived in the property look to a 1031 exchange as their primary deferral tool rather than to the personal residence exclusion rules.

Gain is calculated as the sale price minus the property's adjusted basis, which is the original cost plus capital improvements, minus depreciation claimed over the holding period. The resulting gain is generally split between unrecaptured Section 1250 gain, taxed federally at up to twenty-five percent, and the remaining capital gain, taxed at the applicable long-term rate, with Massachusetts applying its own flat rate on top of the federal liability.
Massachusetts generally taxes long-term gain at its flat rate applicable to most income and taxes short-term gain, on property held one year or less, at a higher state rate. A separate surtax can also apply to total income above a periodically adjusted threshold, which a large one-time rental sale can push a Boston, MA owner over even in an otherwise moderate income year.
A 1031 exchange defers rather than eliminates capital gains and depreciation recapture tax. The gain carries forward into the replacement property's basis and remains subject to tax if that replacement property is later sold outright rather than exchanged again.
Depreciation deductions taken each year reduce the property's adjusted basis, and a lower basis produces a larger calculated gain at sale. This is why a Boston, MA rental held for many years often generates a larger taxable gain, driven significantly by the unrecaptured Section 1250 component, than a simple comparison of purchase price to sale price would suggest.
Yes. Boot is treated as recognized gain up to the total gain realized, and it is generally drawn first from the depreciation recapture component before reaching the lower-taxed capital gain portion, which means even modest cash boot on a heavily depreciated Boston, MA rental can create a disproportionately large current tax bill.
