Form 5329 - 2018 Tax Year Checklist
What Form 5329 Covers
Form 5329 for tax year 2018 reports additional taxes under federal tax laws on tax-favored account activity, including qualified retirement plans, Individual Retirement Arrangements, and education savings accounts. Form 5329 also applies when an IRS penalty is triggered by early distributions, excess contributions, or required minimum distributions that were not handled elsewhere.
This return does not compute Roth conversion income or IRA basis, which belong on Federal
Form 8606 and the related Pension and Annuity Income reporting rules. Form 5329 instead calculates the excise tax amounts and documents exceptions when Form 1099-R distribution coding does not match the taxpayer’s facts.
When Form 5329 Must Be Filed
Form 5329 is filed with Form 1040 or Form 1040NR when additional taxes apply, or when an exception must be claimed for early distributions from qualified plans. Form 5329 is commonly needed when Distribution Code 1 appears on Form 1099-R, but an exception or partial exception applies under IRS guidelines.
If no income tax return is required for tax year 2018, Form 5329 may be filed by itself and must be signed as a standalone filing. Filing should follow the 2018 tax filing deadline instructions, using the correct mailing method and retention practices for U.S. tax reporting.
Ten-Step Checklist (2018 Form 5329)
Step 1: Confirm Form 5329 applies for tax year 2018
Determine whether additional taxes apply due to early distributions, excess contributions, or minimum distributions tied to a retirement account or other tax-advantaged accounts. Confirm the issue was not fully handled by Form 1099-R coding, direct reporting on tax returns, or corrections already completed within allowed timeframes.
Step 2: Gather required account and tax records
Collect all Federal Form 1099-R statements, year-end retirement account balances, and prior-year Form 5329 entries when excess contributions are carried into tax year 2018. Include
Form 8606 details for Roth IRA or nondeductible IRAs so that basis and recapture amount items are not incorrectly pushed into IRS Form 5329.
Step 3: Identify early distributions subject to additional tax
Review taxable early distributions taken before age 59½ from qualified retirement accounts, traditional IRAs, Roth IRA accounts, endowment contracts, or other qualified retirement plans.
Confirm the taxable portion from Form 1099-R matches the income included on Form 1040 or
Form 1040NR for tax year 2018 reporting.
Step 4: Apply the SIMPLE IRA two-year rule when relevant
Determine whether a SIMPLE IRA distribution occurred within two years of first participation, because that period can trigger a higher additional tax rate under tax regulations. Verify the participation start date through the IRA custodian records and confirm which portion, if any, must be computed using the special rule.
Step 5: Review contribution limits and excess contributions
Compare 2018 IRA contributions to the contribution limit rules for traditional IRAs and Roth IRA accounts, and identify any carried excess contributions from prior years. If an excess remained at year's end, compute the 6% excise tax and confirm whether corrective withdrawals were timely completed under Publication 590-A guidance.
Step 6: Evaluate education and ABLE account distributions
Identify taxable distributions included in income from Coverdell ESAs, 529 accounts under a qualified tuition program, or an ABLE account under Achieving a Better Life Experience rules. If an exception does not apply, compute the 10% additional tax using Part II rules and retain support for the education savings accounts reporting.
Step 7: Determine Required Minimum Distribution obligations
Determine whether minimum required distributions applied for tax year 2018 and calculate the
Required Minimum Distributions using Publication 590-B tables, including the Uniform Lifetime
Table where applicable. If mandatory distributions were short, compute the shortfall and apply the 50% additional tax on Line 55, unless a penalty waiver request is supported.
Step 8: Separate inherited account rules from owner accounts
Apply inherited IRA rules separately from owner retirement accounts, because beneficiary distribution rules differ and must be tracked using the appropriate life expectancy table methods.
Avoid applying the latter 10-year rule concepts to 2018 inherited accounts, and confirm whether the Single Life Expectancy Table is required for beneficiary calculations.
Step 9: Complete the correct parts of Form 5329
Use Part I for early distributions, Parts III through VIII for Excess contributions across account types, and Part IX for minimum distribution shortfalls when required. Ensure calculations align
with IRS Form 5329 line instructions, including Line 54 for the shortfall and Line 55 for the additional tax computation.

Step 10: Review, attach, and file accurately
Confirm that the Form 5329 amounts flow to the correct excess on the 2018 tax return, including
Schedule 4, as required by the IRS instructions for that year. Retain Form 1099-R, workpapers, and correspondence with financial advisors, because documentation is critical if an IRS penalty, audit review, or correction question arises.
After Filing: Recordkeeping and Issue Prevention
Retain the completed IRS Form 5329, supporting Federal Publication 590-A and Federal
Publication 590-B worksheets, and any exception evidence for early distributions or penalty waiver submissions. Keep records long enough to support the filing position, especially when excess contributions or minimum distributions create multi-year carry-forward effects.
If a platform message appears during preparation, such as an error message or linked news item, treat it as informational and rely on IRS publications and instructions for accuracy. When state taxes apply, confirm whether separate state reporting exists, because California Revenue and Taxation Code rules may differ from federal tax laws for certain retirement items.
