Robot Taxes: The Debate

Whether governments should tax automation to slow job losses or fund support for workers, and why most economists are sceptical.

As automation spreads, some people have suggested a robot tax: a tax on companies that replace workers with machines or software. The idea gained attention in 2017 when Bill Gates suggested that robots replacing workers could be taxed, and the European Parliament debated, but rejected, a proposal for one.

The arguments for

Funding transitions: revenue could pay for retraining and support for displaced workers.
Replacing lost tax revenue: governments collect income and payroll taxes from workers. If machines replace workers, those revenues fall.
Slowing disruption: a tax could slow automation, giving workers and communities time to adjust.
Levelling the playing field: in many tax systems, labour is taxed more heavily than capital, which may encourage firms to automate more than they otherwise would.

Research by Daron Acemoglu and co-authors has argued that the U.S. tax system favours capital over labour, encouraging excessive automation, and that making taxes more neutral could improve outcomes.

The arguments against

Defining a robot is hard: is a dishwasher a robot? Accounting software? AI? Any definition would be arbitrary.
Slowing productivity: taxing automation could discourage investment that raises productivity and living standards.
International competition: firms might move production to countries without such taxes.
Better alternatives: many economists prefer broader tools, such as taxing capital income, reforming labour taxes or funding retraining from general revenue.

South Korea’s approach

South Korea, with one of the world’s highest numbers of industrial robots per worker, reduced tax incentives for automation investment in 2017, which some described as a mild form of robot tax.

The definition problem

A bank replaces some tellers with ATMs, a supermarket installs self-checkout machines, and an office adopts software that automates bookkeeping. All reduce jobs, but in different ways. A robot tax would need to decide which of these count, and how to measure the jobs they replace. This practical problem is a major reason governments have not adopted robot taxes.

Thinking the debate is about stopping technology

Most supporters of robot taxes do not want to stop automation, but to manage its pace, fund support for workers and correct tax systems that may favour machines. The debate is about how to share gains and costs.

Key takeaways

A robot tax would tax companies for replacing workers with automation.
Supporters say it could fund worker support and correct tax systems that favour capital.
Critics say robots are hard to define and taxes could slow productivity.
Many economists prefer making taxes neutral between labour and capital.
