Semi-Retirement

Semi-retirement replaces the cliff of a traditional retirement with a slope. Instead of going from a full paycheck to none, you cut back to part-time hours, move to consulting or project work, take a seasonal or bridge job, or turn a skill into a small business. Earned income covers part of the budget, and the rest comes from savings, a pension or, eventually, Social Security.

The financial case is that every dollar you earn is a dollar you don’t withdraw, which keeps your withdrawal rate low in the years when a market drop does the most lasting harm.

Semi-retirement overlaps with Barista FIRE, which uses the same mix of part-time work and portfolio withdrawals but starts decades earlier and sizes the portfolio deliberately. Semi-retirement more often describes the late-career years, and it is what many plans for early retirement turn into in practice.

Some employers turn semi-retirement into a formal program, often called phased retirement. You keep your job at reduced hours and, in some plans, start drawing part of your pension while you work.

The federal government offers a clear model. With agency approval, a retirement-eligible federal employee can move to a part-time schedule, typically half-time, draw a matching share of the annuity, and spend at least 20% of working hours mentoring. Private employers can do something similar: the tax code lets a pension plan pay benefits to employees who have reached 59½ and are still working, and many 401(k) plans allow in-service withdrawals at that age, though each plan sets its own rules.

Without a formal program, reduced hours are a negotiation. Ask how fewer hours affect health plan eligibility, the 401(k) match, pension accruals and any retiree health benefits, since some of these depend on full-time status.

Many semi-retirees claim Social Security while still earning. Before full retirement age, the earnings test applies: for 2026, SSA withholds $1 of benefits for every $2 you earn above $24,480, and in the year you reach full retirement age, $1 for every $3 above $65,160, counting only earnings before the month you reach it. Only wages and net self-employment profit count, not pensions, investment income or withdrawals.

The test costs less than it looks. Withheld benefits are credited back through a higher monthly benefit once you reach full retirement age, and a special rule, usually in your first retired year, pays a full benefit for any whole month SSA considers you retired. Each year SSA also reviews the records of beneficiaries who work: if your latest year of earnings is one of your highest, it recalculates your benefit and pays the increase, retroactive to January of the year after you earned the money.

Work income also affects how benefits are taxed. Once half your benefits plus other income passes $25,000 for a single filer or $32,000 on a joint return, part of the benefit becomes taxable, up to 85% above $34,000 or $44,000. Because those thresholds are low, even modest part-time pay can make benefits taxable, as provisional income explains.

Before 65, health insurance is often the hardest piece, because many employer plans cover only full-time staff. Marketplace coverage, a spouse’s plan or COBRA fill the gap.

After 65, working changes how Medicare fits. If you have group coverage through your own or your spouse’s current job at an employer with 20 or more employees, that plan pays first and Medicare second, and you can delay Part B without a penalty until the work or the coverage ends, then sign up during an 8-month Special Enrollment Period. With fewer than 20 employees, Medicare pays first. Retiree plans also pay after Medicare, and COBRA may cover only a small part of costs once you are eligible, so neither is a reason to delay signing up.

Earned income keeps retirement accounts open. You can contribute to an IRA up to the lesser of your taxable compensation or $7,500 for 2026 ($8,600 at 50 or older), with no age limit. Part-time pay can also fund workplace deferrals, including catch-up contributions. If you still work for the employer sponsoring your plan, its required minimum distributions can generally wait until you retire, unless you own 5% or more of the company; IRAs get no such delay.

Semi-retirement is not automatically the better path. It trades some freedom for a sturdier plan, and it depends on work being available on your terms.

It tends to suit people who like their field, can sell their skills in smaller pieces, and want a gradual change rather than an abrupt one. It fits less well when an industry has no part-time market, when health may limit work, or when the only way to cut hours is to change employers and lose benefits.
