Two New Jersey-based companies and one with a large footprint in the state have a total of $57 billion in tax havens, which helped saved the companies billions in income taxes over six years, according to a recent report.

The report by the anti-poverty charity Oxfam claims that 50 of the top U.S. corporations, companies that receive trillions in taxpayer funds, stashed more than $1.4 trillion in off-shore accounts, contributing to creating a lower corporate tax rate, according to income tax records gathered by the group.

The reduced rate effectively saved the 50 business behemoths $336 billion through their foreign their tax havens and a convoluted corporate tax system, the report "Broken at the Top" claims.

Two of the top businesses that have reaped benefits from these domestic and international loopholes, are New Jersey-based Johnson & Johnson and Prudential Financial.

The full list of 50 companies can be found here.

The New Brunswick-based healthcare conglomerate, J&J, has 58 subsidiaries in tax havens holding $53.4 billion, according to the report, and only pays a 20.5 percent tax rate -- almost 15 percent less than the statutory tax rate.

Prudential Financial, the Newark-based Fortune 500 insurance holding company, has put $2.40 billion into its 39 off-shore subsidiaries while receiving $2.46 billion in taxpayer assistance, the report shows. The company paid a tax rate of half the statutory rate at 17.5 percent.

The report claims J&J underpaid in taxes to a tune of $16.2 billion over six years, and Prudential should have paid $1.8 billion more in income taxes.

J&J and Prudential both posted billion of dollars in profits between 2008 and 2014, the tax years analyzed in this report, totaling $111.8 billion and $10.7 billion, respectively, in earnings before income taxes.

The other company on the list with two large cooperate campuses in Morristown and Parsippany is currently in the midst of a union strike after contract negotiations broke down this week: Verizon Communications.

Verizon, which is headquartered in New York City, holds $1.3 billion in off-shore accounts in an undisclosed number of subsidiaries, according to the report.

The report claims, the telecom giant has only paid a 15.8 percent income tax on average for the years of this study. Verizon also has received almost $1.5 billion in federal assistance.

Oxfam claims that these top 50 companies have significantly benefitted from the current state of the corporate tax code and spent a total of $2.7 billion on lobbying for federal policy.

Verizon, J&J and Prudential spent a combined $209 million on lobbying efforts over those six years, it said.

The report calculated the companies' tax breaks by taking the difference their self-reported tax rate and the statutory rate and finding what the business would have paid under the 35 percent rate between 2008 and 2014.
