Roth vs. pre-tax contributions: How to decide what fits your retirement

As a financial advisor, I meet people at many different stages of life. Some are retirees with years of experience, others are just starting out after college, and many are workers who participate in retirement plans.

That means the questions I hear also cover a wide range. Some are complicated financial issues, while others are as basic as, “Should I be saving for retirement?”

The answer to that one is yes.

One of the questions I hear most often is whether Roth contributions are the better choice, especially for people using employer-sponsored plans such as 401(k)s or deferred compensation arrangements.

Most people have heard the term “Roth” by now. In simple terms, Roth contributions mean you pay tax on the money now, put those dollars into the account, and later withdraw both contributions and earnings tax-free in retirement.

Pre-tax contributions work the other way around. You get the tax break now, but you pay income taxes when you take the money out in retirement.

Which approach makes more sense? In most cases, it comes down to whether you expect your tax rate to be higher now or later.

When Roth contributions can make sense

Roth contributions can be especially appealing when your income is still relatively low and you have time for your earnings to grow. If you expect your income to rise over your career and possibly move you into a higher tax bracket later, paying taxes now may be the smarter move.

For example, if you are in the 12% federal tax bracket now but expect to be in the 22% bracket when you begin withdrawing retirement funds, paying tax at today’s lower rate can be beneficial.

That is one reason Roth accounts are often promoted to younger workers who are early in their careers and likely to earn more in the future.

When pre-tax contributions can make sense

Pre-tax contributions become less attractive for people and families already in higher tax brackets.

For instance, if you are currently in the 32% federal income tax bracket, it may be hard to justify paying that rate on Roth contributions today if you could withdraw the money later at a lower tax rate.

Another point that is often overlooked is that retirement spending needs are usually lower than working income. While employed, a large share of income goes toward saving, payroll taxes, and other work-related costs. Once retired, many of those expenses go down or disappear. As a result, you may not need nearly as much income to support the same lifestyle.

Older adults may also receive larger tax deductions, including an additional standard deduction for those age 65 and older, along with other deductions that can apply under certain income limits.

All of this can create opportunities for retirees to withdraw money at tax rates that are lower than the rates they faced during their highest-earning years.

Using both strategies together

Choosing between Roth and pre-tax does not have to be an all-or-nothing decision. Having both kinds of retirement accounts can provide valuable flexibility later on.

In retirement, withdrawals can be managed from both accounts. Traditional withdrawals can be used to fill lower tax brackets, while Roth withdrawals can cover additional income needs beyond that point without adding more taxable income.

The main goal is not simply to avoid taxes now or to build the biggest tax-free account possible. It is to decide when paying taxes makes the most sense for your situation.
