Upgrade 401(k) unlocks $70K
- Congress already changed the rule. Under SECURE 2.0, small employers can replace a SIMPLE IRA with a safe-harbor 401(k) during the same year. - The real jump is in 2026 limits: SIMPLE employee deferrals cap at $17,000, while a 401(k) can reach $24,500 plus employer money. - That means owner-operators can move from a low-ceiling plan to a roughly $72,000 shelter — but only with the right setup.
Small-business retirement plans sound interchangeable, but they really are not. A SIMPLE IRA is easy and cheap, which is why a lot of owners start there. The problem shows up later — once profits rise, the plan that felt convenient starts capping how much money you can shelter. That is why this “upgrade to a 401(k)” idea matters now: the law changed, and the contribution gap is big enough to be worth real attention. (irs.gov) ### What actually changed? SECURE 2.0 added a rule that lets employers replace a SIMPLE IRA with a safe-harbor 401(k) plan during a year. Before that, the general rule was harsher — once a SIMPLE IRA started, you had to keep it for the full calendar year. The IRS flagged this specific change in Notice 2024-2, and its older SIMPLE IRA FAQ still reflects the (irs.gov)lly, the old blanket “you can’t switch midyear” line is no longer the whole story. (irs.gov) ### Why does the SIMPLE IRA ceiling feel tight? Because the employee deferral limit is much lower. For 2026, the SIMPLE IRA salary-reduction limit is $17,000, with a $4,000 catch-up for age 50 and up. Some workers in certain SIMPLE plans get a higher SECURE 2.0 limit, but the baseline is still far below a regular 401(k). And SIMPLE plans force the employer (irs.gov)d of the broader menu that a 401(k) can offer. (irs.gov) ### What does a 401(k) open up? A lot more room. For 2026, the employee elective-deferral limit for a 401(k) is $24,500. On top of that, total annual additions in a defined-contribution plan can go to $72,000 in 2026, not counting age-50 catch-up contributions. That is where the viral “about(irs.gov)to support it. (irs.gov) ### Why is this especially attractive to owners? Because an owner can wear two hats — employee and employer. In a 401(k), that means making elective deferrals and then adding employer contributions, often through profit-sharing. In a SIMPLE IRA, the structure is narrower and the ceiling is lower. So if a bu(irs.gov) starts favoring the 401(k) fast. (irs.gov) ### Is the headline number always available? No — and this is the catch. Hitting roughly $72,000 usually requires enough compensation and the right plan design. A solo owner or very small firm may be able to get there more easily than a firm with many employees, because testing, matching, and safe-harbor rul(irs.gov)s. (irs.gov) ### What about cost and complexity? That is the tradeoff. SIMPLE IRAs are popular because they are easy to establish, have no annual filing requirement for the employer, and work well for firms with 100 or fewer employees. A 401(k) can deliver much more flexibility and a much bigger tax shelter, but it usually brings more administration, more plan design choices, and often higher costs. (irs.gov) ### So who should care? High-earning owner-operators, especially ones who started with a SIMPLE IRA for convenience and now want to save aggressively. If you are nowhere near the SIMPLE cap, this is mostly noise. But if you are bumping into it, the law change matters because it turns a once-rigid annual decision into a more tactical one. (irs.gov) ### Bottom line This is not a new loophole. It is a real rule change plus a real math change. A SIMPLE IRA is still the easy starter plan, but a safe-harbor 401(k) now gives growing businesses a much bigger runway — potentially around $72,000 a year in 2026 — if the setup fits. (irs.gov)
