The room rate you see online is rarely what you pay in Boston. Occupancy taxes stack to roughly 14.95%, and they catch many travelers by surprise at checkout. This calculator breaks down each tax component and shows your real out-the-door hotel bill.
How it works
Four occupancy taxes apply to the pre-tax room rate. They are each a percentage of the room rate, not of each other, so they are summed rather than compounded:
state_tax = rate * 0.057 (Massachusetts 5.7%)
local_tax = rate * 0.060 (Boston local option 6%)
ccf_tax = rate * 0.0275 (Convention Center surcharge 2.75%)
tourism_fee = rate * 0.005 (Tourism District 0.5%)
nightly_tax = state_tax + local_tax + ccf_tax + tourism_fee
nightly_total = rate + nightly_tax
stay_total = nightly_total * nights
The four rates total 14.95%, so a $250 room incurs about $37.38 of tax per night, or roughly $287.38 per night all in.
Tips and notes
These figures cover occupancy taxes only. Many Boston hotels add a separate mandatory resort or destination fee, and parking is almost always extra — see the Boston parking cost estimator. Short-term rentals follow a similar state-plus -local structure but may carry an additional community impact fee. Always check the itemized folio at checkout, since rates are set by statute and can change between fiscal years.
