By switching to a new system that's designed to focus on domestic economic activity, congressional tax writers also imposed a two-tiered levy on that accumulated foreign income: Cash will be taxed at 15.5%, less liquid assets at 8%. Companies can pay over eight years.

Apple has the largest offshore cash reserves of any U.S. company, with about $252 billion at the end of September, the most recently reported fiscal quarter. The tax rate indicates that Apple is likely bringing a majority of its overseas cash back to the U.S., leaving only a small portion for international investments like retail stores.

“They're going to have well over $200 billion by the end of this year that will be available for incremental investments, capital returns and M&A,” said Matthew Kanterman, a Bloomberg Intelligence analyst. The new tax law lets U.S. companies bring overseas cash reserves back home in one year and pay the resulting tax bill over eight years. “And Apple hasn't historically done big M&A,” he said.

The $30 billion in capital expenditures will come as part of $350 billion that Apple expects to spend in the U.S. over the next five years. The 20,000 new jobs include additional Apple employees at its campuses, data centers, and retail stores, but not third-party developers for iPhone and Mac apps, an economy Apple has touted in the past.

Apple said that part of the $30 billion in capital expenditures will go toward a new U.S.-based campus, new data centers and additional supplier investments. The company, which opened a new headquarters in Cupertino last year, said its new U.S. site initially will be focused on employees who provide technical support to Apple product users. The new location, which Apple said it will announce later this year, will be similar to the company's existing campus in Austin, Texas, for supply-chain and technical-support employees.

Apple said it will increase its local manufacturing fund, announced last year, from $1 billion to $5 billion, indicating that it will be sourcing more components for its products domestically. As part of the original fund, Apple invested in Corning Inc. and Finisar Corp., companies that make components for iPhone glass screens and lasers for Face ID and AirPods, respectively.

“These are probably many capital expenditure initiatives and new site build-outs that Apple was already planning on doing regardless of repatriation,” said Michael Olson, an analyst at Piper Jaffray, who has the equivalent of a buy rating on the stock.

“What's not said in this release is that there is more potential for increased buybacks for shareholders and acquisitions that might not have taken place if it were not for the cash influx from overseas,” Olson said. Apple typically provides updates on its share buyback program when it announces second quarter earnings.
