A 403(b) plan, also known as a tax-sheltered annuity (TSA) plan, is a retirement plan for certain employees of public schools, employees of certain tax-exempt organizations, and certain ministers.
Individual accounts in a 403(b) plan can be any of the following types.
An annuity contract, which is a contract provided through an insurance company,
A custodial account, which is an account invested in mutual funds, or
A retirement income account set up for church employees. Generally, retirement income accounts can invest in either annuities or mutual funds.
There are three benefits to contributing to a 403(b) plan.
The first benefit is that you do not pay tax on allowable contributions in the year they are made. You do not pay tax on allowable contributions until you begin making withdrawals from the plan, usually after you retire. Allowable contributions to a 403(b) plan are either excluded or deducted from your income. However, if your contributions are made to a Roth contribution program, this benefit does not apply. Instead, you pay tax on the contributions to the plan but distributions from the plan (if certain requirements are met) are tax free.
The second benefit is that earnings and gains on amounts in your 403(b) account are not taxed until you withdraw them. Earnings and gains on amounts in a Roth contribution program are not taxed if your withdrawals are qualified distributions. Otherwise, they are taxed when you withdraw them.
Excluded. If an amount is excluded from your income, it is not included in your total wages on your Form W-2. This means that you do not report the excluded amount on your tax return.
Deducted. If an amount is deducted from your income, it is included with your other wages on your Form W-2. You report this amount on your tax return, but you are allowed to subtract it when figuring the amount of income on which you must pay tax.
Who Can Participate in a 403(b) Plan?
Employees of tax-exempt organizations established under section 501(c)(3) of the Internal Revenue Code. These organizations are usually referred to as section 501(c)(3) organizations or simply 501(c)(3) organizations.
Employees of public school systems who are involved in the day-to-day operations of a school.
Employees of cooperative hospital service organizations.
Civilian faculty and staff of the Uniformed Services University of the Health Sciences (USUHS).
Employees of public school systems organized by Indian tribal governments.
Certain ministers (explained next).
Example
A minister employed as a chaplain by a state-run prison and a chaplain in the United States Armed Forces are eligible employees because their employers are not section 501(c)(3) organizations and they are employed as ministers.
The following types of contributions can be made to 403(b) accounts.
1. Elective deferrals . These are contributions made under a salary reduction agreement. This agreement allows your employer to withhold money from your paycheck to be contributed directly into a 403(b) account for your benefit. Except for Roth contributions, you do not pay tax on these contributions until you withdraw them from the account. If your contributions are Roth contributions, you pay taxes on your contributions but any qualified distributions from your Roth account are tax free.
2. Nonelective contributions . These are employer contributions that are not made under a salary reduction agreement. Nonelective contributions include matching contributions, discretionary contributions, and mandatory contributions from your employer. You do not pay tax on these contributions until you withdraw them from the account.
3. After-tax contributions . These are contributions (that are not Roth contributions) you make with funds that you must include in income on your tax return. A salary payment on which income tax has been withheld is a source of these contributions. If your plan allows you to make after-tax contributions, they are not excluded from income and you cannot deduct them on your tax return.
4. A combination of any of the three contribution types listed above.
