Wall Street banks are booking big losses because of Trump's new tax rules - and they can be traced all the way back to the financial crisis

  • Citigroup, Goldman, and other banks are announcing multi-billion dollar writedowns because of the new tax rules that take effect next year.
  • There are two main reasons for the losses: a provision in the plan taxing overseas profits, and a revaluation of tax assets that for some banks date back to the financial crisis.
  • Despite these announced losses, which are comparatively small, banks are still thrilled about the tax plan.
  • "It's a very very small price to pay for what they got out of this," said Isaac Boltansky, director of policy research at Compass Point, told Business Insider.

Like most businesses, banks should be pleased with President Donald Trump's $1.5 trillion tax reform bill that passed this month. It will cut corporate tax rates from 35% down to 21%.Advertisement

Banks are expected to benefit even more than most companies - since they tend to pay full tax rate to begin with, and because potential economic and inflationary stimulus from the bill could give their lines of business a shot in the arm. They're expected to see earnings grow in the neighborhood of 15% as a result of tax reform, according to research firm Compass Point.

So why have the big Wall Street banks been announcing giant losses in December?

Goldman Sachs reported Friday that its fourth-quarter and 2017 earnings would take a $5 billion hit on account of tax reform; Citigroup earlier in the month said it expected to take a $20 billion loss if the tax plan went through.

Other bulge-bracket banks are also expecting billion-dollar losses resulting from tax reform, though not as large as Citi and Goldman Sachs.

There are two primary reasons banks are reporting some big losses in the fourth quarter from the tax plan: the repatriation provision, and the necessity to revalue some assets on their balance sheet that, in some cases, connect all the way back to the financial crisis.

Overseas profits are getting taxed, whether you bring them home or not

First, repatriation, which is fairly straightforward.Advertisement

In part to help pay for some of the tax cuts to corporations and individuals and encourage companies to bring profits back to the U.S., the new rules levy taxes on earnings that corporations have sitting overseas.

Currently, companies pay taxes on overseas profits when they bring them back to U.S. soil - a process they can delay and drag out.

Now, corporations will pay a 15.5% tax on their overseas cash earnings, whether they bring them back or not. Advertisement

"That's why you're seeing large multinational companies taking into account a new tax on their earnings overseas," Isaac Boltansky, director of policy research at Compass Point, told Business Insider.

Goldman Sachs attributed two-thirds of its $5 billion loss to this provision.

A tool to defray tax costs is getting a haircut

Taking the corporate tax rate down to 21% from 35% is a major boon for the banks, which tend to pay closer to the full tax rate than other industries. But that also means revaluing some assets kept on their balance sheets intended to help defray tax costs. Advertisement

What we're referring to are "deferred tax assets," an accounting procedure that can get a bit wonky, but for these purposes it functions like this: When a business takes a big loss in a given year, it can use the size of that loss to lower its tax burden in future years. Since it can lower what you pay in taxes and thus increase profits in the future, it's considered an asset - but you have to estimate it fairly given the current tax code and report that asset on your balance sheet.

This is what's primarily going on with Citigroup, which took massive losses during the financial crisis that it has been using in the ensuing years as deferred tax assets.

But if the overall corporate tax rate drops, the value of those tax assets drop as well.Advertisement

"A lot of banks put up large losses during the crisis," said Jesus Bueno, a VP at Compass Point and the firm's bank expert. "If you're going from a 35% tax rate to a 21% tax rate, the value of those losses becomes less over time."

Banks now have to adjust their valuation of their tax assets, "impairing" a large chunk on their balance sheets to account for the tax rate falling by 14 percentage points. As Bueno put it: A $35 million tax asset would now need to be written down to $21 million. Advertisement

The law requires that companies do this during the period when the legislation is enacted, which is the quarter we're in right now - hence why you've got a rash of banks announcing losses after the tax legislation passed this December.

It's important to keep in mind: None of this was a surprise to banks, and they're not upset about it, either.

"This was very much expected," Bueno said. "The benefit from the ongoing corporate tax rate more than offsets the hit to deferred tax assets."Advertisement

Boltansky added: "It's a very very small price to pay for what they got out of this."
