ST. PETERSBURG, Russia (AP) — It's time to make Google, Apple and other multinational companies pay more taxes. That's the message from President Barack Obama and leaders of the world's other leading economies this week.

The head of the Organization for Economic Cooperation and Development, Angel Gurria, told The Associated Press on Friday that the leaders signed on to the new tax plan at the Group of 20 summit in St. Petersburg, Russia.

The new rules would make it harder to hide money in tax havens and force companies to pay tax in the countries where they make profits.

But it may take years to get the new tax treaties and laws into place. And advocacy groups say poor countries should also be included.
