The Post Office says you'll only be able to pay bills at five of its outlets from April.
It says the decision will affect customers paying Manx Utilities, Manx Telecom, Isle of Man Energy, TV Licensing, rates or Fixed Penalty Notices.
From Wednesday, April 1 you'll only be able to pay at outlets in Strand Street in Douglas, Castletown Co-op, Port Erin Post Office and Spar shops on Parliament Street in Ramsey and Atholl Street in Peel.
The Post Office says you'll only be able to pay bills up to £650 at the counters in future.
It says it's because of regulatory requirements.
