It’s never too early to think about retirement income planning and start saving: Guardian’s 2025 Workplace Benefits Study has found that two top stressors for American workers are having a source of guaranteed income in retirement (46%), and having retirement savings last as long as needed in retirement (44%).¹ And, nearly 4 in 10 adults have regrets about how they’ve prepared for retirement so far.¹

The good news is, there are a lot of different retirement savings plans and account options that can help build up your nest egg, and your employment status will help determine what's available to you. Some retirement accounts — called "employer-sponsored plans" are only available if you're employed by a business, tax-exempt or non-profit entity, or the government. Others — known as "Individual Retirement Accounts" — aren't dependent on job status. Both categories of plans have significant tax advantages compared to a regular savings or brokerage accounts, and are specifically designed for long-term retirement savings. Here's a brief overview of the most popular types of plans.

Employer-sponsored plans

An employer-sponsored retirement savings plan is one of the most valuable benefits you can have as an employee. While participation isn't always mandatory, almost all financial professionals would advise you to do so if at all possible. Why? Employer contributions, including matching and discretionary contributions, are a key benefit of many employer-sponsored plans, and not taking advantage of them is like leaving money on the table. They’re also easy to use, because automatic payroll deductions are the primary way to contribute to these plans. Employer-sponsored plans usually have higher contribution limits than IRAs (see below), which can help you to accumulate more money over the same period. Plus, older employees can often make catch up contributions, allowing them to contribute additional amounts beyond the standard limits. But it's important to understand that different kinds of employers can offer different kinds of plans, and each has its own rules for how contributions are made and when they are taxed. Common employer-sponsored plans include:

Plan	401(k)	403(b)	457(b)	Thrift savings plans (TSP)
Type of employer	Available to non-governmental employers including tax-exempt companies	Tax-exempt organizations	State and local governments, and some tax-exempt organizations	Federal employees and some military members

How Funds grow	Investment earnings grow tax-deferred until retirement	Investment earnings grow tax-deferred until retirement; Roth options also allow tax free withdrawals	Investment earnings grow tax-deferred until retirement; Roth options may allow tax-free withdrawals in retirement	NA

Retirement withdrawals are subject to income tax; no early-withdrawal penalties if an employee separates before age 59 ½; capital gains are not taxed until withdrawal; catch up contributions available.

What about traditional pension plans?

Also known as a "defined benefit plan," these are employer-funded plans that guarantee a specific monthly income during retirement, typically based on years of service and salary history. Some defined benefit plans are traditional pension plans, and others are cash balance plans, which combine features of pensions and defined contribution plans. These have become much less common in recent years as many employers have transitioned to employee-funded "defined contribution plan" alternatives, such as 401(k) plans.

Individual Retirement Accounts (IRAs)

An Individual Retirement Account — or IRA — is a tax-advantaged retirement savings account funded and managed by an individual — you — without any employer involvement. They are typically used by self-employed people and by those wishing to supplement their employer-sponsored plans. To contribute to most IRAs, you must have earned income, though a spousal IRA allows a worker’s spouse to contribute without earned income.

There are two main types of IRAs, and the primary difference has to do with when you pay income taxes. Contributions made to traditional IRAs are typically made with pre-tax dollars – which reduces taxable income for the year. Investment growth is tax-deferred, but taxes are paid when you withdraw funds in retirement. On the other hand, a Roth IRA is funded with after-tax dollars (so you don't get a tax deduction when you contribute), but investment growth is tax-deferred, and qualified withdrawals are tax-free during retirement. Other features, tax benefits, and types of IRAs include:

Plan	Traditional IRA	Roth IRA	Spousal IRA	Rollover IRA	SEP IRA(Simplified Employee Pension)
Best suited for	Those who will be in a lower tax bracket after retiring	Those who will be in a higher tax bracket after retiring	A non-working spouse or spouse with limited income	Those who want to transfer funds from an employer-sponsored plan	Self-employed individuals or small business owners
How contributions are made	Pre-tax contributions for immediate tax savings (tax deductibility subject to income limits)	After-tax contributions, but qualified withdrawals are not taxed	Can be pre-tax (Traditional IRA) or after-tax (Roth IRA); working spouse can contribute for non-working spouse (even if the spouse has no earned income)	For those changing jobs or retiring; funds from the original IRA are not taxed as they roll over into the new IRA	Have higher contribution limits than Traditional IRAs; contributions are tax deductible, subject to certain limits
How funds grow	Investment earnings grow tax-deferred until retirement	Investment earnings grow tax-deferred until retirement	Investment earnings grow tax-deferred until retirement	Investment earnings grow tax-deferred until retirement	Investment earnings grow tax-deferred until retirement
Other features	Retirement withdrawals are subject to tax; penalty-free early withdrawals are allowed for certain purposes	Qualified retirement withdrawals are not taxed; early withdrawals that are not qualified withdrawals may be subject to a penalty³	Pre-tax (Traditional) contributions get immediate tax savings; after-tax (Roth) contributions get tax-free qualified withdrawals in retirement	Can be used to consolidate retirement savings from different employers	Business owners can contribute on behalf of employees

Other ways to save for retirement

Employer-sponsored retirement plans and IRAs are among today’s most popular retirement savings vehicles, but they are not the only options. Other popular choices include annuities, which can provide guaranteed income in retirement, and cash-value life insurance policies.

Annuities

These are financial products that convert a sum of money into a steady stream of income during retirement. While annuities can provide lifetime income that helps ensure you don't outlive your savings, they can also be complex investments.

Investments grow tax-deferred, allowing money to grow faster than in taxable accounts.
Options include immediate annuities that begin paying out immediately after purchase or deferred annuities that allow the investment to grow over time before starting income payments.
Annuities can be structured as fixed, where investment growth is based on a set rate of interest, or variable, where investment growth (and later income payments) fluctuates based on the performance of underlying market investments.
Some annuities include features like inflation protection, which adjusts the payments to maintain purchasing power.

Cash-value life insurance policies

While the primary purpose of a life insurance policy is to provide a death benefit payout to help protect beneficiaries’ financial well-being, whole life insurance and universal life insurance policies can also be used as a retirement savings vehicle. In addition to protecting your loved ones in the event of an untimely death, these policies provide a tax-advantaged way to accumulate funds that can be used before or after retirement. As children become self-sufficient adults, many people use their cash-value life insurance to supplement other retirement accounts. (Please note that term life insurance does not accumulate cash value and has no benefit in terms of retirement savings.)

A portion of every premium payment goes into a cash account which grows over time and can be accessed while the policyholder is still living.
The cash value component of the policy grows tax-deferred, so your money can grow faster.
Policyholders can borrow against the accumulated cash value without triggering taxable events, providing a source of tax-free income in retirement.
Some policies may allow you to convert the cash value into an annuity, providing a steady stream of income during retirement.
Policy loans and withdrawals affect the guarantees by reducing the policy’s death benefit and cash values.

Frequently asked questions about retirement savings plans

The main types of retirement plans include employer-sponsored 401(k) plans, 403(b) plans, individual retirement accounts (IRAs) such as Traditional and Roth IRAs, simplified employee pension (SEP) IRAs for self-employed individuals, SIMPLE IRAs for small businesses, defined benefit plans, and profit-sharing plans. 401(k) and 403(b) plans allow employees to contribute a portion of their pre-tax salary, while IRAs offer personal retirement accounts with tax advantages. SEP IRAs and SIMPLE IRAs are for self-employed individuals and small businesses. Defined benefit plans provide a fixed benefit based on factors like salary and service, and profit-sharing plans involve employers contributing a portion of company profits.

401(k) plans are offered by many employers, both large and small, and allow employees to contribute a portion of their pre-tax salary toward their retirement savings. The popularity of 401(k) plans can be attributed to their convenience, as contributions are deducted directly from the employee's paycheck and the potential for employer matching contributions, which can help accelerate retirement savings. The amount individuals can contribute to their 401(k) plans in 2025 has increased to $23,500, up from $23,000 for 2024. Additionally, 401(k) plans may offer a wide range of investment options, allowing individuals to customize their portfolios based on their risk tolerance and financial goals.
