When might workers be exempt from paying income taxes?

Workers might be exempted from paying income taxes when they don't earn enough money.

Explanation:

Income Tax: It is tax that the individuals or businesses are required to pay to the government based income earned by them during the year.

Low income earners are exempted from paying income taxes.

If you earn an income that does not exceed the standard deduction, not only do you not need to pay taxes, you don't need to file. For example, a married couple under the age of 65 would need to earn at least $24,400 before the IRS requires them to file their taxes. If both spouses are 65 or older, they do not need to file or pay taxes until their income exceeds $27,000.

Income below threshold

Explanation:

There are different threshold for different categories of people. If your income falls below the threshold in your category, you would be tax exempt.

For instance, in 2019, if you were under 65 years of age and single you would have to earn a minimum of $12,200 to pay tax.
