Saving for retirement can feel confusing, even if you have been doing your best at it for years. Differing advice can add to that confusion. For example, you may hear that a Roth IRA is always smart, but that is not always true. Your Roth IRA could turn into a surprising retirement mistake if your tax rate becomes higher in retirement than it is today.

For this reason and others covered in this article, it's important to know when a Roth IRA helps and when another account might serve you better.

The ultra-rich have also been investing in art from big names like Picasso and Bansky for centuries. And it's for a good reason: Contemporary art prices have outpaced the S&P 500 by 136% over the last 27 years.

A new company called Masterworks allows everyday investors to buy a small slice of $1-$30 million paintings from iconic artists, all without needing any art expertise.

If you have at least $10k to invest, see what Masterworks has on offer. (Hurry, they often sell out!)

What is a Roth IRA?

A Roth IRA is a type of individual retirement account. You fund it and invest with money that you have already paid income tax on, so you do not get an immediate tax break. In exchange, your qualified retirement withdrawals are tax-free.

Roth IRA contribution limits

The IRS places a restriction on the amount of money you can deposit in an IRA per year. For 2026, the total IRA limit is $7,500 if you are under 50. If you are 50 and above, you can donate a maximum of $8,600 due to a catch-up provision.

There are also income limits to Roth IRA contributions. By 2026, single filers will be able to typically contribute the full amount of Roth with incomes less than $153,000. Married couples can also file jointly when their income is less than $242,000 to make the full contribution.

The appeal of tax-free growth

Tax-free growth is the greatest advantage of a Roth IRA, provided that the rules are adhered to. You pay tax on the money prior to investing, and thus the gains in the account can later be withdrawn in retirement without tax. This is very beneficial when you invest your money over a long period of time.

Imagine you put in a total of $200,000 over time and end up with $1.2 million. That represents a $1 million increase that can never be taxed as long as the withdrawals are qualified. The longer your money has to grow, the greater this tax-free growth is able to improve your retirement income.

Avoid required minimum distributions

Traditional IRAs and many workplace plans make you start taking money out at age 73. These required minimum distributions (RMDs) can push up your taxable income and may affect other costs or taxes. Roth IRAs are different because original owners do not have to take these forced withdrawals during their lifetime.

If you do not need the money, you can leave it in your Roth as long as you live. The account can keep growing and stay available for later years or for your family. This flexibility lets you choose how much income to show each year and may help your savings last longer.

Leave money to your family

A Roth IRA can also be a useful estate planning tool. Heirs who inherit a Roth IRA usually must empty the account within a set number of years, often 10. However, their withdrawals are generally tax-free if the original Roth met basic timing rules, such as the five-year rule.

This means children or other heirs can use the money without adding to their taxable income for that year. They may choose to spread withdrawals out to keep some tax-free growth going. For families who want to pass along assets efficiently, a Roth IRA can be kinder than only leaving pre-tax accounts.

Be aware of the tax timing risk

A major con of the Roth IRA is that it can work against you if your tax rate now is higher than it will be later. In that case, you may be paying more tax than needed on your contributions today. A traditional IRA or pre-tax 401(k) might be smarter because they give you a deduction now and smaller tax later.

For example, someone taxed at 32% today might retire in a 20% bracket. Paying 32% on Roth contributions now can cost more than paying 20% later on traditional withdrawals. In this kind of situation, the traditional account may leave more money in your pocket after taxes.

The danger of easy withdrawals

Roth IRAs also have a behavior trap that can quietly damage your retirement. You can usually withdraw your original contributions at any time without taxes or penalties. That makes the account feel like a handy backup emergency fund for short-term needs.

The problem is that every early withdrawal takes away years of possible growth. If you pull $2,000 at age 30 that might have earned about 8% each year, you could lose nearly $30,000 by age 65. What feels small today can become a big missing piece of your future income.

Changing rules can create uncertainty

Another con is that tax laws can change over time. Some current rules are set to expire or shift, which could raise or lower future rates. It is hard to know exactly what your tax bracket will be many years from now, even with careful planning.

This uncertainty makes it tricky to be all-in on Roth or all-in on traditional. If future tax rates end up lower than you expect, paying tax today for a Roth might look less smart. If rates end up higher, you might wish you had done more Roth and less traditional instead.

Bottom line

A Roth IRA is not magic to build a tax-free retirement income. It works best when you can make the money go away over many years, and when your tax rate in the future may be the same or even higher than it is now. Traditional IRAs and pre-tax 401(k)s often serve people in higher current tax brackets better.

One smart move for seniors is to have a combination of each of them rather than opting for one. That combination allows you to adapt to tax laws and life as it changes, leaving a larger nest egg to work for you rather than the government.
