The group, including Britain, Canada, France, Germany, Italy, Japan and the United States, has visions of a global tax rate of at least 15 percent on the multinational behemoths, AFP reported.
The move comes as US President Joe Biden is pressing to raise the corporate tax rate, taking particular aim at companies reaping fortunes.
"Pressure has been building over the years," said Georgetown University law professor Lilian Faulhaber.
"I think some of it, honestly, is just political."
The pandemic's hit to economies has made it harder to balance government budgets, the professor noted. At the same time, voters see stories of internet firms raking in profits while avoiding taxes and, perhaps, taking advantage of market dominance.
"More and more voters have gotten upset about this," Faulhaber said.
Silicon Valley giants are increasingly under fire in Europe and the United States due to concerns about wielding monopoly-like power.
"Maybe the resentment bleeds from one side into the other in terms of tax avoidance and the influence these companies have over the way we live," said Alan Auerbach, a taxation specialist in the University of California, Berkeley, Economics Department.
Outdated tax code
Nations out to optimize tax revenue from tech firms face powerful companies adept at using data, analytics and ingenuity to build markets and profits.
In the United States, internet companies take advantage of opportunities for tax credits from investments or recruiting. Elsewhere, companies use legal strategies to shift profits to countries with low tax rates and move losses to places where taxes are steep.
"It's wrong to call them ethically or morally defective because they take advantage of the incentives that we provide them," Auerbach said.
"The international tax system is designed for an earlier era; when companies had a clear residence and their production occurred in one place," added Auerbach, co-author of recently released Taxing Profit in a Global Economy.
Using a 19th century tax code in a 21st century economy is a recipe for losing revenue, he reasoned.
Part of the G7 reform plan involves taxing multinational corporations where they make their money rather than where they have offices or factories.
"There are all these people who are both receiving services and providing eyeballs," Faulhaber said, referring to online audiences cashed in on by internet firms relying on digital advertising.
"Previously, their role has not been recognized in international tax law."
In Europe, such a tax code change would be felt in Ireland, which has attracted companies such as Apple with a favorable tax environment.
The three-day summit of G7 began on Friday in the English seaside resort of Carbis Bay.
