"With this tax relief, in 2023, no worker who earns less than 404,062 pesos (about $2,378 monthly) will pay the tax," Massa said in a tweet.

The minister did not disclose the fiscal cost of the decision, which he said is set to benefit some 312,864 workers.

The previous floor stood at 330,000 pesos ($1,942.32).

With this update, Massa said fewer than 600,000 wage earners in the country will pay the tax, less than 10% of the country's total workforce.

Higher-income workers will also get some tax relief in the form of personal deductions and tax scale brackets, he added.

The decision is likely to be welcomed at a time when inflation is forecast at around 100% for 2022, cutting into Argentines' purchasing power.
