Retirement planning for the self-employed and small business owners, comparing Solo 401(k) and SEP-IRA plans, including 2026 contribution limits, employee deferrals, employer profit sharing, catch-up rules, Roth options under SECURE 2.0, and plan setup deadlines
The DB(k) plan under Section 414(x) let small employers bundle a 401(k) and a pension into one plan, yet almost nobody adopted it. Here's why it failed — IRS double filing fees, unchanged administrative work, weaker owner contributions — and how a DB/DC combo of a cash balance plan plus 401(k) profit-sharing can push an older owner's deductible contributions past $480,000 a year.
A Solo 401(k) with voluntary after-tax contributions lets self-employed owners shelter up to $72,000 in 2026 — or $83,250 with the age-60-to-63 catch-up — by converting after-tax dollars to Roth with no income limits. Here's how the three contribution buckets work, a worked example at $150,000 of net earnings, and what your plan document must allow.
A QLAC lets you move up to $210,000 — the 2026 SECURE 2.0 lifetime limit — from a traditional IRA, SEP-IRA, or 401(k) into a deferred annuity the IRS excludes from RMD calculations until payments start, as late as age 85. Here are the rules, a worked example, and the break-even math showing when to skip it.
For 2026 the IRS caps total 401(k) contributions at $72,000 versus a $24,500 employee deferral limit; business owners can convert the after-tax gap between the two into a Roth account tax-free using the mega backdoor Roth strategy.
The DOL's 2024 Retirement Security Rule was formally vacated in March 2026, reverting fiduciary status for 401(k) rollover advice to the 1975 five-part test — here's what plan sponsors and savers should ask advisors now.
The enhanced premium tax credits expired January 1, 2026, restoring the 400% FPL cliff. This guide walks self-employed filers, S-corp owners, freelancers, and early retirees through the 2026 applicable percentage schedule, MAGI levers like Solo 401(k), SEP-IRA, HSA, and Section 162(l), and Form 8962 reconciliation strategies to avoid five-figure repayments.
Compare the 2026 Solo 401(k) and SEP-IRA limits side by side — when each plan wins, how the SECURE 2.0 super catch-up adds $11,250 for ages 60–63, the mega-backdoor Roth strategy for after-tax conversions, the 20% versus 25% Schedule C calculation, and the Form 5500-EZ filing required once plan assets cross $250,000.
A cash balance plan lets a 55-year-old business owner deduct roughly $230,000 a year in retirement contributions — far above the 401(k) ceiling — because a defined benefit pension caps the retirement benefit, not the annual deposit, so limits scale with age rather than income.
Section 107 lets ordained ministers exclude designated housing costs from federal income tax, but the allowance is still added back for SECA and only an in-advance written designation survives audit. A practical guide to the three-part cap, Form 4361's irrevocable opt-out, and the 403(b) designation that keeps a retired pastor's distribution income-tax-free for life.
Section 1041 lets spouses transfer property tax-free during and after divorce, but carryover basis, the six-year window, QDROs, ISO conversions, and post-TCJA alimony rules quietly reshape every settlement. A working guide to what must be fixed before the decree is signed.
For the self-employed, a Solo 401(k) often shelters more than double what a SEP-IRA does at the same income — a $90,000 earner can contribute $47,000 vs. $22,500 in 2026. This guide covers the limits, the Roth option, the pro-rata rule, and the December 31 deferral deadline.
