The SECURE 2.0 super catch-up: Starting in 2025, employees age 60-63 can make a 'super catch-up' contribution to 401(k) plans — the greater of $10,000 or 150% of the regular catch-up limit. For 2026, the super catch-up is $11,250 (150% of $7,500). This is in addition to the regular $23,500 employee deferral — for a total of $34,750 for employees age 60-63. Practitioners should proactively advise clients approaching age 60 about this opportunity.

Backdoor Roth IRA for high-income clients: Clients above the Roth IRA income limits can use the backdoor Roth strategy: (1) make a non-deductible traditional IRA contribution ($7,000); (2) immediately convert to Roth IRA. The conversion is tax-free if the traditional IRA has no pre-tax balance. The pro-rata rule applies if the client has other traditional IRA balances — practitioners must calculate the taxable portion of the conversion.

| Single | Yes | $79,000 | $89,000 |
| MFJ (contributing spouse covered) | Yes | $126,000 | $146,000 |
| MFJ (contributing spouse not covered; other spouse covered) | N/A | $236,000 | $246,000 |
| Single | No | No phase-out | Full deduction |
| MFJ (neither spouse covered) | No | No phase-out | Full deduction |

Retirement plan contributions are one of the most powerful tax reduction tools available. For a client in the 37% bracket who maximizes a 401(k) ($23,500 + $7,500 catch-up = $31,000), the tax savings are $11,470. For a client who also contributes to a defined benefit plan ($200,000), the total tax savings can exceed $85,000. Practitioners should review retirement plan contributions for every client at mid-year — not just at year-end.
Practitioner Planning Checklist — 2026 Retirement Contribution Limits
- Review all client files for 2026 retirement contribution limits exposure annually. Identify clients who may benefit from planning strategies related to this topic before year-end.
- Document all elections and positions taken. Maintain contemporaneous records supporting any tax positions. The IRS can audit returns up to 3 years (6 years for substantial understatements, unlimited for fraud).
- Coordinate with estate and financial planning. Tax strategies do not exist in isolation. Coordinate with the client's financial advisor and estate planning attorney to ensure consistency across all planning documents.
- Model multiple scenarios before advising clients. Use tax projection software to model the impact of different strategies. Present clients with a clear comparison of options, including the tax cost and non-tax considerations of each.
- Stay current on IRS guidance and legislative changes. This area of tax law is subject to frequent IRS guidance, revenue rulings, and legislative changes. Subscribe to IRS e-News and monitor the Uncle Kam Legislative Updates section for developments.
- Review state tax implications. Federal tax strategies may have different or adverse state tax consequences. Verify the state tax treatment of any strategy before advising clients, particularly for clients in high-tax states (CA, NY, NJ, IL, MA).
- Obtain client consent for aggressive positions. For any position that is not clearly supported by statute or regulation, obtain written client consent and disclose the position on the return (Form 8275 or 8275-R if contrary to regulations).
- Set follow-up reminders for multi-year strategies. Many tax strategies span multiple years (installment sales, 1031 exchanges, Roth conversion ladders). Set calendar reminders to review and adjust strategies as circumstances change.
Common Mistakes and Pitfalls — 2026 Retirement Contribution Limits
- Failing to document the business purpose of deductions. The IRS requires contemporaneous documentation for most deductions. Receipts, logs, and business purpose statements should be maintained at the time of the expense, not reconstructed later.
- Missing filing deadlines and extension requirements. Many elections and filings have strict deadlines. Late elections (e.g., S-Corp election, §754 election) may be irrevocable or require IRS consent to make late. Calendar all critical deadlines.
- Overlooking state conformity issues. Many states do not conform to federal tax law changes. A strategy that works at the federal level may create unexpected state tax liability. Always check state conformity before advising clients.
- Ignoring the interaction with other tax provisions. Tax provisions rarely operate in isolation. A strategy that reduces one type of tax may increase another (e.g., reducing AGI for EITC purposes may increase the ACTC but reduce other credits). Model the full tax impact.
- Failing to consider the economic substance doctrine. The IRS can disregard transactions that lack economic substance beyond tax benefits. Ensure that all tax strategies have a genuine business purpose and economic substance beyond tax savings.
- Not reviewing prior-year returns for missed opportunities. Many tax benefits can be claimed on amended returns within the statute of limitations (generally 3 years). Review prior-year returns for missed deductions, credits, and elections.
