Here is a list of reasons why you might reasonably decide not to use an IRA for your retirement savings:

Of course, there are also reasons why some paycheck-reliant, tax break-loving citizens forgo the many perks of contributing to an individual retirement account. But some of those excuses don’t stand up to reality when fact-checked against a little document known as the Internal Revenue Code — a roughly five-phone-book-thick minefield of fine print detailing the IRS’ do’s, don’ts, exceptions, exemptions and every nuanced rule there is about IRAs. (Dig in!)

How do untruths about IRAs get started? Probably somewhere along the way someone who wasn’t fluent in IRS-speak misinterpreted a few of the rules. Erroneous information was repeated. Fallacies were mistaken for facts. Falsehoods spread faster than middle-school speculation about so-and-so having a crush on so-and-so. Worst of all, these half-truths continue to cause countless savers to miss out on years of investment growth.

It’s time to set the record straight.

Here are some common myths that lead people to assume that an IRA just isn’t for them:

The IRS doesn’t allow a lot of things (like claiming your kid’s guinea pig as a dependent), but going back for thirds at the retirement account salad bar isn’t one of them, as long as you stay within the allowable annual contribution limits. In an employer-sponsored retirement plan (a 401(k), 403(b), 457 or Thrift Savings Plan), you’re allowed to contribute $18,000, plus an additional $6,000 if you’re age 50 or older. On top of that, if you are eligible to contribute to both a traditional and a Roth IRA, you can divert money into each in the same year as long as the total combined amount does not exceed the maximum annual allowable contribution limit of $5,500 (plus a $1,000 catch-up contribution if you’re 50 or older). Add it up and a serious saver could sock away as much as $23,500 a year, or up to $30,500 for those age 50 and older.

If you’re not flush enough to max out everything at once, here’s how to settle the IRA vs. 401(k) decision and the classic Roth IRA vs. traditional IRA.

Talking to you, heirs/heiresses. It’s true that you’re ineligible to contribute to a Roth IRA at all if you earn “too much” in the IRS’ eyes ($196,000 or more if you’re married and filing jointly or $133,000 for single filers in 2017). However, even those who pull in a massive annual paycheck are allowed to open and fund a traditional IRA. But here’s the caveat that can make the rules more confusing: Your household income as well as whether you or your spouse have access to a workplace retirement plan — e.g., a 401(k) — affect how much of your traditional IRA contribution the IRS will allow you to deduct from your taxes. (Here’s more on IRA contribution limits.) Which leads us to our next myth…

The traditional IRA’s upfront tax deduction gets all the glory, but that doesn’t mean there’s nothing in it for you if you don’t qualify to take that deduction. Remember, investments within IRAs grow tax-deferred. That’s true even for nondeductible IRAs. In other words, you don’t have to pay income tax on any investments in the account that produce dividends, interest or capital gains until you withdraw the money in retirement.

Another situation where a nondeductible IRA will help you save on taxes is if you decide to convert the IRA into a Roth (via the backdoor Roth IRA strategy.) Remember, you already paid taxes on those contributions. So when you make the conversion, the only money subject to income taxes will be any investment gains within the IRA before the conversion.

The IRS clearly states that you must have earned income in order to be eligible to contribute to an IRA. But there is an exception to this rule: the spousal IRA. If you are, for example, a stay-at-home parent and are married to someone who is earning money and file a joint tax return, contributions to a Roth or traditional IRA can be made on your behalf. The IRA must be set up in the nonworking spouse’s name, and eligibility and deductibility are based on what applies to the spouse with greater compensation.

You really shouldn’t. Remember, the “R” in IRA stands for retirement, and in most cases dipping into the account before age 59½ results in a 10% early withdrawal penalty and, potentially, an income tax IOU from Uncle Sam. But if you’re skipping out on the IRA because you don’t want to give up access to your money, you should know that there are exceptions to the no-touch rule. Both the Roth and traditional IRA waive the early withdrawal penalty for a first-time home purchase and to pay for certain qualified higher education expenses. If there are other reasons to need to get to your cash, Roth IRA distribution rules are more flexible than what applies to traditional IRAs and 401(k)s. The IRS allows tax- and penalty-free withdrawals of contributions from a Roth IRA at any time and for any reason.

Lucky you! You have until April 18 (the tax filing deadline) to contribute to an IRA for the 2016 tax year. (Here’s NerdWallet’s picks for best brokers for IRAs if you don’t already have an account. Just make sure you indicate on the money you add to the account that it’s your 2016 contribution.) As long as you’re writing checks you might as well start adding funds to your IRA for 2017. The earlier you contribute to an IRA the more time you give your money to compound and grow.
