What type of tax levied on income that will be used in retirement?

The tax levied on income that will be used in retirement is typically referred to as an income tax, which applies to earnings and is collected by federal, state, and sometimes local governments. Additionally, specific retirement accounts like 401(k)s and IRAs may offer tax advantages, such as tax-deferred growth or tax-free withdrawals, depending on the type of account. Contributions to these accounts may be made pre-tax or after-tax, influencing how they are taxed upon withdrawal in retirement.
