The quickest way to know if you contributed to an IRA is to look for IRS Form 5498. Every IRA custodian is required to send one to you and to the IRS for any year you put money in, so a dollar amount in Box 1 (traditional) or Box 10 (Roth) is direct proof.1Office of the Law Revision Counsel. 26 USC 408 – Individual Retirement Accounts – Section: Reports If you don’t have that form in front of you, your tax return, bank records, pay stub, and the custodian itself can all give you the same answer.
Start With Form 5498
Form 5498 is the single most definitive record of an IRA contribution. Because you can contribute for the prior tax year up to the April filing deadline, custodians don’t finalize the form until after that window closes. The IRS gives them until June 1 of the following year to send it.2Internal Revenue Service. Instructions for Forms 1099-R and 5498
Two boxes tell you what you need to know:
- Box 1 shows contributions to a traditional IRA, not counting SEP, SIMPLE, or rollover amounts, which appear in their own boxes.
- Box 10 shows contributions to a Roth IRA.
A dollar figure in either box confirms you contributed for that tax year.2Internal Revenue Service. Instructions for Forms 1099-R and 5498 Keep every Form 5498 you get. You may need it years later to prove your tax basis when you start taking withdrawals.
Check Your Tax Return
Your filed return can also reveal an IRA contribution, but what you look for depends on the type of IRA.
Traditional IRA Deduction
A deductible traditional IRA contribution shows up on Schedule 1 (Form 1040), line 20, labeled “IRA deduction.”3Internal Revenue Service. 2025 Schedule 1 (Form 1040) – Additional Income and Adjustments to Income A number on that line means you contributed to a traditional IRA that year and took the deduction.
Roth Contributions Leave No Line
Roth contributions are made with after-tax dollars, so they never appear as a deduction. An empty Schedule 1 line 20 does not mean you skipped the year. It may just mean the account is a Roth, in which case Form 5498 is your primary tool.
Nondeductible Contributions and Form 8606
If your income was too high to deduct a traditional contribution but you contributed anyway, you should have filed Form 8606 to record the after-tax basis and avoid being taxed twice on that money later.4Internal Revenue Service. Instructions for Form 8606 Scan your past returns. A Form 8606 attached to a given year is a clear signal you made a nondeductible traditional IRA contribution that year.
Follow the Money Through Your Bank Statements
Monthly bank statements often show recurring transfers to an investment firm. Look for outgoing amounts going to companies like Vanguard, Fidelity, or Schwab. The transaction description usually includes the firm’s name or an internal reference. Most online banking portals let you filter by payee or date range to isolate these transfers quickly.
A transfer to an investment firm doesn’t by itself prove the money landed in an IRA rather than a regular brokerage account. It just tells you where to look next. Once you’ve identified the destination, confirm the account type with the firm.
Read Your Pay Stub Carefully
Some employers offer a payroll deduction IRA, where part of your paycheck goes directly into an IRA you opened yourself. If your pay stub shows a line labeled “Payroll Deduction IRA” or something close to it, that money is being forwarded to your account each pay period.5Internal Revenue Service. Payroll Deduction IRA
One thing to know: payroll deduction IRA contributions do not appear on your W-2, and the “Retirement Plan” checkbox in Box 13 is not marked for this arrangement.5Internal Revenue Service. Payroll Deduction IRA Your employer’s only role is forwarding the deduction. The IRA belongs to you, not to any employer plan. So your W-2 alone won’t tell you whether a payroll deduction IRA exists. Check the stub.
Don’t Mistake a Workplace Plan for an IRA
A 401(k), 403(b), SIMPLE IRA, or SEP is not the same as a traditional or Roth IRA, and each shows up on your W-2 differently:
- 401(k) salary deferrals appear in Box 12 with code D.
- 403(b) salary deferrals appear in Box 12 with code E.
- SIMPLE IRA salary reductions appear in Box 12 with code S.
- SEP contributions aren’t in Box 12, but the “Retirement Plan” box in Box 13 is checked.6Internal Revenue Service. Common Errors on Form W-2 Codes for Retirement Plans
Code S in Box 12 means you’re in a SIMPLE IRA, which is a type of IRA but follows different contribution rules than a traditional or Roth. Code D or E means you have a 401(k) or 403(b), which is not an IRA at all. A checked Box 13 with no code S in Box 12 may point to a SEP IRA funded by your employer.7Internal Revenue Service.

Log In or Call the Custodian
If you know you have an account at a brokerage or bank, the fastest confirmation is to log in. The account overview page labels each account by type, usually “Traditional IRA,” “Roth IRA,” “SEP IRA,” or “Individual Brokerage Account.” Holding stocks or mutual funds in an account doesn’t make it an IRA on its own. The custodian’s designation is what makes it one.
If the label isn’t clear online, call customer service. Custodians keep detailed records to meet federal reporting rules and can tell you whether the account sits under Section 408 (traditional IRA) or Section 408A (Roth IRA) of the Internal Revenue Code.8Office of the Law Revision Counsel. 26 USC 408 – Individual Retirement Accounts While you’re on the line, you can also ask what you contributed for each recent year.9Internal Revenue Service.

Request an IRS Transcript
Lost the form, don’t have the return, and can’t reach the custodian? Request a wage and income transcript from the IRS. It compiles what employers and financial institutions reported to the IRS about you, including IRA contribution data from Form 5498. You can pull one through your IRS Online Account, by calling 800-908-9946, or by mailing Form 4506-T. Online transcripts are available immediately; mailed copies take five to ten days.10Internal Revenue Service. Get Your Tax Records and Transcripts
Which Source to Trust
If two sources disagree, treat Form 5498 or the custodian’s records as the authoritative answer. Bank statements only prove that money left your checking account. A pay stub only proves your employer forwarded a deduction. The tax return only reflects what you claimed. The custodian’s records are what the IRS sees, and what will govern the treatment of your account when you eventually take money out.
