The infographic is false. Shell does not receive $2 Billion in subsidies a year. They do receive tax breaks, but not for "no real reason".
The $2 Billion claim in the infographic seems to be either a misrepresentation or a misreading of values found on some websites online. An approximate value of $2 Billion for Royal Dutch Shell has been presented on mic.com, cheatsheet.com, The Washington Post, etc. However, this amount is for total tax subsidies received since 2003, as mic.com put it.
Royal Dutch Shell has managed to nab over $2 billion in subsidies since just 2003 alone.
This is backed up by the supposed source of the mic.com article, Good Jobs First, who self describe in their About Us page as
[A] national policy resource center for grassroots groups and public officials, promoting corporate and government accountability in economic development and smart growth for working families. We provide timely, accurate information on best practices in state and local job subsidies, and on the many ties between smart growth and good jobs. Good Jobs First works with a very broad spectrum of organizations, providing research, training, communications and consulting assistance.
Good Jobs First, among other things, serves as a watchdog for government subsidies, and maintains a database of subsidies and tax bonuses awarded to companies. Of note is the page for Royal Dutch Shell. There are four things of major note on this page.
The value presented on the page for RDS is $1.725 Billion, not $2 Billion as mic.com claims (while linking to this site at the same time)
$1.65 Billion, or 95.7%, comes from a single deal with the state of Pennsylvania for a tax-credit to build a massive petrochemical plant there.
The tax subsidies are a summation of all subsidies since 2003, not per year as the image claims.
The image tries to link federal SNAP benefits to total tax benefits for RDS. Of the $1.725 Billion listed on the page for RDS, total federal tax benefits account for $4.9 Million, or 0.2% of all total tax benefits.
This is futher backed up by an article on Mother Jones. In the article, they estimate approximately $200 million in tax subsidies for RDS. However, there is no source for their estimate.
Even though OP did not ask about the "no real reason" portion of the image, I've elected to at least address it. While "no real reason" is a subjective statement, the majority of tax write offs for RDS (and "Big Oil" companies as a whole) are not something exclusive to the Oil Industry. David Blackmon, writing for Forbes in an article entitled Oil And Gas Tax Provisions Are Not Subsidies For "Big Oil"
The truth is that the oil and gas industry receives the same kinds of tax treatments that every other manufacturing or extractive industry receives in the federal tax code.
Basically, Percentage Depletion is the oil and gas industry’s version of a depreciation deduction for its main asset, which is the oil and natural gas in the ground, commonly known as its reserves. Every industry of any kind is allowed a depreciation deduction on its assets under the U.S. Tax Code, but, far from being a “subsidy” for “big oil”, this tax treatment was in fact repealed for all integrated oil companies, i.e., ExxonMobil, Shell, BP, etc., in 1975, and is today available only to independent producers and royalty owners.
Another great example of the specious mischaracterization of these tax treatments is the Manufacturer’s Tax Deduction, more commonly referred to as Section 199. The Section 199 provision was enacted by congress in 2004 as a means of encouraging manufacturers to relocate overseas jobs to the U.S., and is in no way specific to or limited to the oil and gas industry. In fact, the oil & gas industry’s ability to take advantage of this provision has already been singled out for limitation – in 2008, Congress reduced the industry’s deduction under this provision to 2/3rds of what other manufacturing industries are allowed to deduct.
Finally, let’s talk about Intangible Drilling Costs (IDCs), another feature of the federal tax code that will enjoy its’ 100th birthday in 2013. Basically, IDCs are the costs incurred by the oil and gas industry in the drilling of its wells. Since drilling wells is the only means of finding oil and natural gas, IDCs essentially amount to what any other industry would be able to deduct as a part of its cost of goods sold, a concept of accounting and tax law as old as the tax code itself.
Independent producers and royalty owners are allowed an election to either a) expense these costs in the year they are incurred, or b) amortize them over a 5-year period. Again, most media reports commonly characterize this as a “subsidy” for “big oil”, as does the Obama Administration. The truth is that “big oil” – the ExxonMobils, Chevrons, Shells and BPs of the world – benefit much less from this tax treatment, it having been severely limited to them by congress in 1986, and again in 1992. And the truth also is that IDCs are not a “subsidy” to anyone engaged in the oil and gas business.
Ultimately, a large portion of tax write-offs that Oil Companies take advantage of are write-offs that are not native or exclusive to the Oil Industry itself, and the taxes that are specific to the Oil Industry are limited in their scope for larger companies.
