The Government has confirmed a review of the property tax will take place before the next election.
A spokesman said the Government wanted to make sure the tax "remains affordable" by delaying a possible increase in the tax in two years time.
The tax is linked to the value of a property.
Based on current rates, some houses could be worth around 70% more in 2016 than they were when the tax first kicked in - meaning the tax would be 70% higher too.
The review would aim to keep the cost from escalating further.
A spokesman said the Government was "acutely aware" of how rising property prices would mean a huge hike in the tax that most people would pay.
And it says the tax will be reviewed - so that it remains "affordable" for households.
The news comes a full two years before the increase would have kicked in - and it's likely to lead to further speculation that an election isn't far away.
