A senior Treasury official has confirmed the Turnbull government is looking at superannuation tax concessions.
Paul Tilley, head of the personal and retirement income division, told a parliamentary inquiry into home ownership on Friday Treasury had spent a lot of time looking at capital gains tax exemptions on investment properties.
"The new prime minister and new treasurer have indicated they're areas, together with superannuation, that we'll look at," Mr Tilley said.
The coalition, under Tony Abbott, ruled out making any adverse changes to superannuation in this term or the next.
Labor has a plan on the table that aims to reduce tax concessions for high-income earners.
