Key takeaways

  • Use retirement tax forms to complete tax returns, not file them back to the IRS. Consider that both Form 1099-R and Form 5498 fall into this category. 
  • Note that Form 1099-R tracks every distribution taken from a retirement account during the year. It shows up by January 31, and it’s the one most retirees deal with most often. Box 7 has one or two codes that tell the IRS what kind of distribution it was — and whether a penalty applies.
  • Don’t forget that Form 5498 arrives after the tax filing deadline, which trips people up every year. Also, keep in mind that IRA custodians have until May 31 to send it, because IRA contributions for the prior year can come in as late as April 15. Keep this for personal records; do not file it. 
  • Form 8606 is the one most likely to cause real problems if ignored. It tracks after-tax money in a traditional IRA. Skipping it could result in the IRS taxing that money twice.
  • Remember that Form 5329 is how the IRS collects the penalty for a missed required minimum distribution. The SECURE 2.0 Act reduced that penalty from 50 percent to 25 percent, effective in 2023. It drops to 10 percent if the issue is fixed within two years.

Every January and May, a certain kind of mail arrives that most retirees don’t quite know what to do with. Forms with numbers in the names. Boxes filled with figures that weren’t requested and don’t obviously correspond to anything on a tax return. The instinct is usually one of two things: file it away and hope for the best, or panic and assume something is wrong.

Neither one is quite right.

These forms carry information that directly affects tax returns, retirement accounts’ tax treatment, and, in some cases, whether the IRS comes looking for a penalty. Keep reading to clearly understand what each one is for and what it does and doesn’t require.

Form 1099-R

Taking out retirement account money in the previous year (in whatever form, traditional IRA, Roth IRA, 401(k), 403(b), pension, annuity, doesn’t matter which), will trigger a Form 1099-R. This form usually arrives in the mail before January 31. Remember that any withdrawal of $10 or more triggers one.

Most retirees get at least one of these every year. Some get several, depending on how many accounts they drew from.

Box 1 has the gross distribution. Box 2a shows the financial institution’s estimate of the taxable amount, and Box 4 shows the federal tax withheld. While the Box 2a number often matches the income that goes on the tax return, it isn’t always the final word. For instance, if someone did a tax-free rollover, Box 2a might still show the full amount, but they will report it as tax-free on their actual return.

Box 7 holds one or sometimes two distribution codes that tell the IRS what kind of withdrawal it was. When two codes appear together, the first describes the primary nature of the distribution, and the second adds context about the account type or the circumstances. Code 7 paired with Code D, for instance, comes up with annuity distributions. Code 4 paired with Code A shows up on death distributions from a Roth. The IRS instructions for Forms 1099-R and 5498 list all the combinations.

The codes most retirees see:

  • Code 7: normal distribution, age 59½ or older, no penalty
  • Code 1: early distribution, under 59½, no known exception
  • Code 4: distribution to a beneficiary after the account owner’s death
  • Code G: direct rollover, meaning the money went straight from one custodian to another. (Doing an indirect, 60-day rollover where the check was made out to the account holder means the holder will usually see a Code 1 or 7 instead, and they have to show the IRS it was a rollover on Form 1040).
  • Code Q: qualified Roth distribution, tax-free

Don’t file this form. Instead, the information goes on Form 1040. Check that the code in Box 7 matches what actually happened. An incorrect code can mean a penalty a retiree didn’t owe or income that appears underreported.

Form 5498

Form 5498 is the form that appears after an account holder has already filed their taxes. It comes from the IRA custodian and covers contributions, rollovers, Roth conversions, recharacterizations, and the account’s December 31 fair market value. 

It usually arrives in late May, after the account holder has already filed. Every year this confuses people — but there’s a structural reason for it. IRA contributions for a prior tax year can come in as late as April 15, so the custodian can’t close the books until then. The IRS gives them until May 31 to get the form out. 

This form is not filed, either. It’s for records and verification. The fair market value in Box 5 is what the IRS and the custodian will use to calculate future RMDs. The contribution amounts in Boxes 1 and 10 are worth checking against what was reported on the actual tax return. If something doesn’t match, that’s when it might be worth calling a tax preparer.

SSA-1099

This SSA-1099 form (officially the Social Security Benefit Statement) comes from the Social Security Administration, not the IRS, and shows up in January. Note that it reports the total benefits received during the prior calendar year. 

This form helps determine how much of an account holder’s Social Security benefits are taxable. That all depends on something called combined income, which the IRS calculates by adding adjusted gross income, any nontaxable interest, and half of the account holder’s Social Security benefits.

If the combined income exceeds $25,000 for a single filer (or $32,000 for married filing jointly), up to 50 percent of the benefits may be taxable. Above $34,000 for single filers ($44,000 for married filers) means that up to 85 percent may be taxable. The ceiling is 85 percent, regardless of how high the income goes.

Box 5 shows net benefits for the year (total benefits received minus any repaid ones). Keep in mind that Medicare premiums are already included in this number, not deducted from it. This Box 5 amount is exactly what a tax preparer or software needs; it goes directly onto Form 1040 (or the IRS worksheet) as the starting point to calculate how much of the account holder’s Social Security is actually taxable.

Form 8606

Form 8606 is the one that causes the most long-term damage when people skip it.

It tracks the basis in a traditional IRA, meaning the after-tax money put in that shouldn’t get taxed again when it comes out. File it in any year that the account holder makes a nondeductible contribution to a traditional IRA, completes a Roth conversion, or takes a distribution from a traditional IRA that has a mix of pre-tax and after-tax money in it.

Without a consistent filing history on Form 8606, the IRS has no record that any of the IRA money was already taxed. So when distributions eventually come out, it all gets taxed again. The IRS imposes a $50 penalty for failure to file without reasonable cause, but the real cost is the double taxation that builds up over the years.

File this form with annual tax returns. If the account holder ever made a nondeductible IRA contribution or done a Roth conversion and they’re not sure whether Form 8606 was filed, that’s worth checking before the next return goes in.

Form 5329

Form 5329 is for retirement account violations – most commonly, a missed required minimum distribution.

Before 2023, missing an RMD meant a 50 percent excise tax on the amount not taken out. The SECURE 2.0 Act cut that to 25 percent starting in 2023, according to IRS Retirement Topics on RMDs. And if the mistake is caught and the missed distribution is corrected within two years, the penalty drops to 10 percent.

The form can also be used to request a waiver. Missed the RMD because of a misunderstanding, an administrative error, or a first-time mistake? Ask for relief by entering zero on the penalty line and attaching a written explanation. The IRS has granted these waivers in many cases. 

File one Form 5329 per year of violation with annual returns.

How a financial advisor can help

These forms interact with each other in ways that aren’t always obvious. A qualified tax professional can check that 1099-R distribution codes match what actually happened, confirm that Form 8606 has been filed every year it should have been, assess whether a Form 5329 penalty waiver is worth pursuing, and reconcile Form 5498 values against prior returns. That kind of cross-form review is where errors tend to surface — and where the cost of missing something tends to be highest.

FAQs

Does getting a Form 5498 mean an amended return needs to be filed? 

Not necessarily. The form is informational, and it’s supposed to arrive late. If the contribution amounts match what the account holder reported and the fair market value looks right, they don’t need to do anything except keep it. If the numbers don’t match what was on their return, that’s worth a conversation with a tax professional before deciding whether to amend.

What if the distribution code in Box 7 of Form 1099-R looks wrong? 

Call the financial institution or plan administrator that issued it. A corrected 1099-R can be requested if the code doesn’t reflect what actually happened. Filing a return with the wrong code can mean a penalty that wasn’t owed or income that looks underreported. If the correction can’t be sorted out before the filing deadline, a tax professional can advise on next steps.

Who has to file Form 8606? 

Anyone who made a nondeductible contribution to a traditional IRA, completed a Roth conversion, took a distribution from a traditional IRA with after-tax contributions, or received a distribution from an inherited IRA with after-tax basis, according to the IRS About Form 8606 page. It’s part of the annual federal return. Not optional in any year one of those things happened.
