The Coalition has downplayed reports that its likely win in next year's general elections would lead to a federal government that is not tax-friendly with tech titans maintaining local operations in Australia.

Opposition communication spokesman Malcolm Turnbull clarified on his Tuesday blog that his party, touted to snatch the government rule from Labor Prime Minister Julia Gillard in 2013, was not eyeing to raise the tax dues currently levied on tech giants like Amazon, Apple and Google.

"I am not proposing any specific change to the existing tax laws or flagging a shift in Coalition policy," Mr Turnbull said in his blog posting, which he wrote following media reports that said he plans to revamp the country's tax models for offshore firms with considerable local presence.

The Australian Financial Review (AFR) carried a new story yesterday that suggested Mr Turnbull was critical of the techniques being employed by tech firms operating in Australia, which allow them to legally avoid higher tax dues.

The senior Liberal member reportedly told the publication that global tech firms were exploiting in-placed loopholes in Australia's tax system, enabling them to rake in more revenues while the country's tax base suffer unrealised revenues.

Mr Turnbull cited the case of Amazon, which he claimed generates hefty revenues on online book orders placed by Australians but evades paying and GST, the same tax dues that local counterparts of the giant online retailer must pay on every book that they push out of their web-based stores.

Clearly, a gaping discrepancy was present in the system, Mr Turnbull said, and unfortunately tech giants were reaping most of the benefits while local online retailers were left to shoulder most of the burdens.

However, the opposition member admitted too that the intricacies of the internet further complicate the situation as a web store being viewed in Australia was likely hosted by a server from another location outside of the country.

Compelling that particular store to pay local taxes while it has to deal with separate tax dues from another location would constitute double-taxation, a concept that experts said was also considered legally unacceptable in Australia.

Mr Turnbull stressed on his blog that the Coalition's main concern for now is to determine whether the country's current tax set up is in tune with the emerging digital trends and not to check on the tax practices of specific tech companies.

"The question is not whether the laws are being complied with (I assume they are) but whether they are adequate in a new, converging digital world," the one-time opposition leader wrote in his blog.

His comments were made in the aftermath of a planned review flagged by Ms Gillard last year, which intends to pore over on the pricing practices of global tech firms that conduct international businesses through their local subsidiaries.

Following the review, the federal government reportedly aims to "properly reflect the economic contribution of (these companies') Australian operations," and subsequently level the playing field.

According to The Australian, if the review would indeed lead to a transfer pricing revamp, the measures would be rolled out retrospectively to July 2004, which would then require tech firms with Australian presence to pay potentially billion in tax dues.

But the initiative was viewed by PriceWaterhouseCoopers (PWC) Australia as counter-productive, stressing that the "retrospective law change is bad tax policy, and this amendment owes more to the government's planned budget surplus in 2013 than any technical legal merit."

"This retrospective amendment has been poorly received by corporate Australia and tax advisers generally," PWC Australia told The Australian.
