The "Backdoor" Roth IRA Strategy

The Roth IRA is an attractive savings vehicle, offering tax-free retirement income and other significant benefits. Unfortunately, income limitations prevent many people from contributing to these accounts. But even if you cannot contribute directly, there is no limit on converting a traditional IRA into a Roth. This "backdoor Roth IRA" strategy allows anyone, regardless of income, to enjoy a Roth IRA's benefits.

Although some lawmakers proposed closing the back door, the Tax Cuts and Jobs Act (TCJA) preserved this option.

Would You Benefit?

Before considering a backdoor Roth IRA, first determine whether a Roth is right for you. The main difference between traditional and Roth IRAs is the timing of income taxes. Traditional IRA contributions are deductible — that is, they are made with pretax dollars — while withdrawals of both contributions and investment earnings are taxable. In addition, withdrawals of contributions or earnings before age 59-½ are subject to a 10% penalty.

Roth IRAs work in the opposite way: Contributions are taxed up front (they are nondeductible), but qualified withdrawals of contributions and earnings are tax and penalty-free. Generally, you can withdraw direct contributions anytime and backdoor contributions after a five-year waiting period. To avoid taxes and penalties on withdrawn earnings, however, you must be at least age 59-½ and the Roth IRA must be at least five years old.

From a tax perspective, a Roth IRA makes sense if you expect your tax rate to be higher in retirement: You are better off paying the tax upfront, when your rate is lower. If you expect your tax rate to be lower in retirement, a traditional IRA may be preferable.

Roth IRAs may also be advantageous if you want to allow the funds to continue growing tax-free, or continue making contributions, beyond age 70-½. With a traditional IRA, you must stop making contributions and begin taking required minimum distributions when you reach that age. A Roth IRA is particularly valuable if you wish to leave the account to your heirs income-tax-free.

What Are the Contribution and Income Limits?

Currently, the maximum contribution to a traditional or Roth IRA is $6,000; $7,000 if you are 50 or older. Roth IRA contributions are phased out when your modified adjusted gross income (MAGI) reaches a certain threshold. This year, contributions for single filers are gradually reduced when MAGI tops $122,000, and eliminated altogether when it reaches $137,000. For joint filers and qualifying widows or widowers, the phase-out range is $193,000 to $203,000.

There are also income limits on the deductibility of traditional IRA contributions if you or your spouse are covered by an employer-sponsored retirement plan. But you can still make nondeductible contributions up to the amounts specified above.

How Does a Backdoor Roth IRA Work?

The backdoor technique works best if you do not have an existing traditional IRA and you are ineligible for deductible contributions. To make a backdoor contribution, you simply make a nondeductible contribution to a new traditional IRA and then convert it to a Roth IRA. Because your contribution is nondeductible, the conversion will not be taxable except to the extent there are any earnings in the account before you convert. If you convert quickly, the tax consequences of a backdoor contribution are virtually the same as a direct contribution.

If you have a traditional IRA with substantial pretax funds, the backdoor technique will come at a tax cost. That is because of the so-called "aggregation" rule. When you withdraw or convert funds from a traditional IRA, this rule treats all of your traditional IRAs as one big account and allocates the funds among those accounts on a pro-rata basis. (See "Aggregation Rule in Action.")

Should You Convert?

Now may be an ideal time to convert a traditional IRA into a Roth, since the TCJA reduced individual income tax rates through 2025. But beware: Depending on the size of your IRA and your other income, converting the account all at once could push you into a higher tax bracket. You may be better off converting the account gradually over several years. Talk to your tax advisor before taking any action.

Sidebar: Aggregation Rule in Action

Suppose you have an existing traditional IRA with a $24,000 balance, consisting entirely of deductible contributions and earnings, and you wish to make a backdoor contribution to a Roth IRA this year. To accomplish this, you make a $6,000 nondeductible contribution to a new traditional IRA and immediately convert it into a Roth IRA.

Under the aggregation rule, the conversion is treated as if the funds were withdrawn from all of your traditional IRAs on a pro-rata basis. In this case, you have $24,000 of pretax dollars in the existing IRA and $6,000 of after-tax dollars in the new IRA. In other words, 80% of your aggregate balance ($24,000/$30,000) is pretax.

The result? When you do the conversion, 80% of the converted amount ($4,800) is taxed as ordinary income.

Guidelines for Deducting Business Meals

The Tax Cuts and Jobs Act (TCJA) eliminated most tax deductions for business-related entertainment, beginning in 2018. It also created confusion over the continued deductibility of business meals. Late last year, the IRS issued a notice clarifying that taxpayers may continue to deduct 50% of eligible business meal expenses and providing temporary guidance on the subject. Businesses may rely on this guidance until proposed regulations become effective.

Five-Part Test

The notice sets forth a five-part test to determine whether business meal expenses are deductible. Taxpayers may deduct 50% of an otherwise allowable business meal expense if:

  1. The expense is an ordinary and necessary business expense;
  2. The expense is not lavish or extravagant under the circumstances;
  3. The taxpayer, or an employee, is present;
  4. Food and beverages are provided to a current or potential business customer, client, consultant or similar business contact; and
  5. In the case of food and beverages provided during or at an entertainment activity, the food and beverages are purchased separately from the entertainment or their cost is stated separately on one or more bills, invoices or receipts. The meal cost must also be reasonable; That is, you cannot circumvent the disallowance of entertainment deductions by inflating the charges for food and beverages.

The notice provides several examples to illustrate the deductibility of meal expenses at an entertainment event. For example, you invite a business contact to a baseball game. You buy the tickets and, at the game, treat your guest to hot dogs and drinks. Although the tickets are a nondeductible entertainment expense, the hot dogs and drinks, which are purchased separately, are 50% deductible.

Now, suppose that you and your contact attend the game in a corporate suite, which provides food and beverages. If the invoice for the suite covers the entire expense, without separately stating the cost of food and beverages, the entire amount is a nondeductible entertainment expense. But if the invoice separately states the cost of food and beverages, that cost is 50% deductible (provided it is reasonable).

Certain Expenses Remain Deductible

The IRS notice focuses on business meals and entertainment activities with current and prospective customers and other business contacts. But several other types of expenses remain deductible after the TCJA. For example:

  • Meal expenses while traveling on business continue to be 50% deductible;
  • Meal and entertainment expenses may be 100% deductible if they are treated as compensation to employees or income to nonemployees; and
  • Reasonable expenses for company recreational or social activities, such as holiday parties and picnics, continue to be deductible. You can deduct 100% of the cost of both meals and entertainment, as long as an activity primarily benefits employees other than officers, owners or highly compensated employees.

Previously, certain meals provided to employees were fully deductible, including meals provided so employees can work overtime and meals furnished on or near the employer's premises (including certain operating expenses for on-premises dining facilities). The TCJA imposes a 50% limit on these deductions through 2025, after which they are disallowed entirely.

Know the Rules

If you incur business-related meal and entertainment expenses, familiarize yourself with current rules on their deductibility and document your expenses carefully. And be sure to keep an eye on regulatory developments that may change the rules.
