Here's exactly how much paychecks changed after tax reform for people at every income level from $20,000 to $269,000 a year

The new tax law, which changed the 2018 tax brackets, went into effect at the start of this year.

By February, many Americans began to notice a bump in their take-home pay because of the law.

The IRS released new guidelines in January, known as tax-withholding tables, that help employers calculate how much to take out of employees' paychecks in taxes, Business Insider's Bob Bryan reported. That amount is paid to the IRS in the employee's name.

At the end of the year, when an employee files their tax return, they get a refund if the amount withheld was too much or pay more if it was too little.

The new withholding amounts hit Americans' paychecks around February 1, and the IRS says that about 90% of workers saw an increase in their take-home pay.

The career site Zippia provided Business Insider with data breaking down the average salaries for employees in various occupations, as well as how their federal tax bill changed under the new tax law. Business Insider used that data to calculate how paychecks have changed.

Below is a look at how people in several different jobs — including fast-food cooks, pilots, and anesthesiologists, among many others — who receive paychecks every other week (meaning 26 a year) have seen their take-home pay change.

The calculations are for a single person who does not have children and is not a homeowner.

The new paycheck amounts account for only federal taxes and FICA taxes — the employee's share of Social Security and Medicare taxes. Depending on where you live, state and local income taxes can further reduce your take-home pay — as can health-insurance premiums, 401(k) contributions, and other deductions you may have.
