The ACT government's rates revenue has risen more than 130 per cent since it embarked on its 20-year-long reform to abolish stamp duty, vastly exceeding increases elsewhere.
Figures from the ABS show the territory government's rates revenue rose from $209 million in 2011-12, before the tax reforms began in the 2012 budget, to $492 million in 2017-18, a 134 per cent rise.
In NSW, where council rates are independently set, rates rose only 32 per cent in the same period, up from about $3.4 billion to $4.5 billion statewide.
Across all state and local governments nationally, rates revenue rose 39 per cent in the seven year period, about 6 per cent a year, from $13.2 to $18.4 billion.
While the ACT's average residential rates rose about 9 per cent a year in recent years, commercial rates have risen faster, and the government's overall rates revenue has risen an average of 19 per cent a year since 2011-12.
While the territory's overall tax revenue has risen about 30 per cent in that time; rising rates has put pressure on Canberra households and businesses, sparking two Legislative Assembly inquiries in recent months.
The data shows the territory's overall tax take rose from about $1.1 billion to $1.7 billion from 2011-12 to 2017-18, a similar increase to the total tax take of councils and state governments in other jurisdictions.
The rising rates revenue has also come as the government faces criticism over its land valuation program, which determines rates charges, with valuation objections doubling in the past decade.
But while the rates portion of that revenue rose some 136 per cent in the six years since the tax reform began, stamp duty revenue has largely remained unchanged.
The reform program would, over 20 years, abolish stamp duty, increase the payroll tax threshold and has already abolished insurance duties, with the revenue loss to be made up through rising rates.
The government had pledged the reforms would be revenue neutral when it began the reforms in 2012.
But it has since backed away from the promise, with Chief Minister Andrew Barr now claiming they would be broadly revenue-neutral in aggregate over the entire two-decade period.
A government spokeswoman said the rise in the rates revenue figures was largely due to the switch to rates, as a more efficient tax base, and was to a lesser degree influenced by the ACT's rising population.
The rates burden in 2017-18 was borne by 158,198 residential properties in the ACT, and 6053 commercial properties, amid record population growth, while unit owners also faced the full brunt of a rates hike of some 30 per cent over two years.
"The review of stage one of tax reform indicated that the overall increase in tax revenue is broadly in line with what would have been achieved without tax reform," she said.
She said the growth in the territory's overall tax revenue, which includes all rates and taxes, was also influenced by economic and population growth, prices and wages and government spending initiatives.
The 2017-18 territory budget forecast about $315 million in rates revenue would come from residential households, with about $172 million from commercial properties, slightly lower than the ABS figure of $492 million.
The data also shows the ACT's stamp duty revenue fluctuated year to year since 2011-12, mainly around the $220 million mark, though it rose to $316 million in 2016-17 before falling to $225 million in 2017-18.
While rates have more than doubled since the reforms began, overall the ACT remains a lower-taxing jurisdiction on a per capita basis than NSW, at about $4295 per person.
The total tax NSW residents paid per capita in 2017-18 was about $4464, the highest level in the country that year.
Average residential and commercial rates are expected to rise by 7 and 6 per cent a year until 2021-22, respectively.
