Bonus: Questions to Ask the Interviewer

What Is FUTA  and SUTA Tax ?

The Federal Unemployment Tax Act (FUTA) is a federal payroll tax that employers pay to fund unemployment benefits at the national level. This tax helps support state unemployment programs and covers administrative costs for running unemployment systems nationwide. 

FUTA ensures that state unemployment agencies have the resources to provide temporary financial assistance to unemployed workers. It also funds extended unemployment benefits during economic downturns when states may run out of money. 

The State Unemployment Tax Act (SUTA) is a state-mandated payroll tax that funds unemployment benefits for eligible workers within that specific state. Unlike FUTA, SUTA tax rates, rules, and wage bases vary by state. 

SUTA taxes directly fund state unemployment benefits for workers who lose their jobs through no fault of their own. These programs ensure financial stability for workers while they search for new employment. 

Key details of SUTA tax: 

• Who pays it? Employers are responsible for SUTA taxes, though in some states (like Pennsylvania, New Jersey, and Alaska), employees also contribute. 
• Tax rates vary by state: SUTA rates depend on state laws, employer industry, and individual employer experience ratings (how often they’ve had former employees claim unemployment). 
• State-specific wage base limits: Unlike FUTA, which has a fixed wage base of $7,000, each state sets its own wage base for SUTA tax. In 2025, these limits range from $7,000 to over $50,000, depending on the state. 
• Purpose of SUTA: These funds are used to provide unemployment benefits to workers in that specific state. 

What Is a W-4?

W-4 forms should be filed with your employer before the first day that you start work. It asks you for your marital status, dependents and withholding allowances. The federal income tax tables are built around those variables. If you pay state tax in your state, the state tax is also dependent upon your answers to those three variables. If you live in Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington or Wyoming, you don’t pay state income tax. The W-4 does not address Social Security or Medicare contributions.

What Is a W-2?

W-2 is short for IRS Form W-2 (Wage and Tax Statement) and it is filed with the IRS by your employer. Any business with employees is required to file a W-2 for each employee who was paid at least $600 for the tax year. A copy of the W-2 is sent to the employee for your records. You may receive it by postal service mail or by email. Employers have to file it by Jan. 31 of the year following the tax year.

A Form W-2 tells the IRS how much you have earned in wages, tips and other compensation for the tax year in question. It also informs the IRS about your contributions toward Social Security and Medicare.
