WASHINGTON — American Airlines is handing out $1,000 bonuses to its employees. So are AT&T, Bank of America, and Nationwide Insurance. The same for Comcast, JetBlue Airways, and US Bancorp.
Such announcements, coming from dozens of companies, have followed passage of the Republican tax plan that President Trump signed into law last month. The plan slashed the corporate tax rate from 35 percent to 21 percent. The companies say the bonuses they’ve announced are a way to share some of their bounty with their workers.
Yet the bonuses are one-time payouts, not the permanent pay raises that Trump and congressional Republicans have said will eventually result from the corporate tax cuts. Over time, bonuses are far less valuable to employees than wage increases.
So far, most companies haven’t said whether permanent pay increases are in the works. And economists caution that the corporate income tax cut’s effect on average pay, if any, might not become apparent for several years.
‘‘As a worker, it’s great to get a one-off bonus, but that doesn’t guarantee anything for the next year,’’ said Stephen Stanley, chief economist at Amherst Pierpont. ‘‘You’d rather have the raise, because next year you’re working off the higher base.’’
Eventually, Stanley thinks the lower corporate tax rates will lead to worker pay raises. He expects companies over the next several years to use some of their windfalls to invest in equipment that would make workers more productive and lead to higher wages.
Other economists remain skeptical. They note that the lion’s share of the corporate tax cut will overwhelmingly benefit shareholders and company owners. That sentiment is one reason stock market indexes are setting new highs almost daily.
‘‘The bulk of the corporate tax cuts should accrue to people who hold stock in companies,’’ said Ethan Harris, chief economist at Bank of America Merrill Lynch. ‘‘Workers benefit much more from a cut in taxes on ordinary income. In other words, better to get a direct cut than a spillover from cuts to others.’’
Beyond the worker bonuses that have been announced, typically for $1,000, about a dozen banks have said they will raise their minimum wages. A handful of mostly small companies, including Washington Federal Bank, have announced pay increases for most of their workforces. And a few, including Visa and Aflac , have said they will raise their contributions to their employees’ retirement plans.
In addition, US workers will begin receiving more take-home pay, probably by next month, as lower tax rates for individuals under the Republican plan kick in.
The Communications Workers of America, a labor union, asked CEOs of large corporations to give workers the $4,000 average income gain that White House officials said would flow eventually from lower corporate taxes. AT&T, the first company to announce bonuses, said it chose the $1,000 bonus instead.
American Airlines, which also employs the communication union’s members, similarly decided to bestow a $1,000 bonus. The union said it appreciated the gesture but asserted in a statement that the bonus ‘‘falls short of the permanent wage increase that working families were promised.’’
The White House has touted the announced bonuses as evidence that the corporate tax cut is benefiting workers, rather than just shareholders, and has dubbed the payouts a ‘‘Trump bonus.’’
‘‘Businesses across America have already started to raise wages, and more than 100 companies have already given bonuses and other benefits to hundreds of thousands of workers as a result of these massive tax cuts,’’ Trump said Monday in Nashville.
The conservative group Americans for Tax Reform, which backed the tax cut, has compiled a list of more than 100 companies that have announced some kind of financial benefit for employees resulting from the tax cut.
Only a few have announced any broad-based pay increases. One that has is Nephron Pharmaceuticals, of West Columbia, S.C. Nephron said it would give a 5 percent raise to most of its 640 employees.
Andrew Chamberlain, chief economist at Glassdoor, said there are practical reasons why most companies would prefer bonuses over pay raises. ‘‘It’s a way for employers to benefit workers without being on the hook for a long-term pay increases,’’ he said.
In some cases, the companies are sharing only a sliver of their tax-cut windfalls. Bank of America’s bonuses will cost it roughly $145 million — about 4 percent of the $3.5 billion that Goldman Sachs estimates Bank of America will receive from the tax cut.
Most economists do expect paychecks to start rising faster for most workers this year, but for a different reason: The US unemployment rate is projected to fall further and could reach a five-decade low of 3.5 percent. A rate that low would be likely to force many companies to sharply raise pay to keep and attract the workers they need.
