Consulting after retirement: earn without a full-time job

Consulting after retirement works best when you start soon after you leave, sell short defined pieces of work (paid expert calls, a fixed project, an advisory seat) and settle three things before the first invoice: what you still owe your former employer, how the income affects Social Security if you are under full retirement age, and the self-employment tax you now pay.

This post is for retired executives and senior professionals who want consulting or other side income without a full-time job. If you want to build a full consulting business, how to become a consultant fits better.

1. Pick the format by how much of your week you want to give

Retired executives have five realistic options, and they differ mostly in how much of your calendar they take.

Format	Time it takes	What to know
Paid expert calls	An hour at a time	You set the rate and can decline any request
Project consulting	A few weeks to a few months	Pays the most per engagement, needs a written scope
Advisory role	A meeting a month, plus messages	Often paid in equity at startups
Interim role	Full-time or close to it, for months	Closest to the job you left
Board seat	Several meetings a year, plus committee work	Hardest to get, slowest to land

Expert calls are the lightest start. GLG's network members page says you set your own rate and are paid after each project at that rate. Guidepoint's advisor page asks for 10+ years of experience and says consultations are often completed within 72 hours of the first request. The posts on expert network calls and getting paid to give advice cover the details.

Interim work is a real job with an end date. The best public figures are British: the UK Institute of Interim Management's 2026 survey of UK interims reported an average day rate of £907, an average assignment of 10.0 months, an average gap of 3.2 months between assignments and an average age of 55.2. Treat them as a rough guide to the shape of the work, not US pay. If you retired to get your weekdays back, skip interim roles; interim executive and fractional executive explain both models.

Board seats favor people like you, slowly. Spencer Stuart's 2025 US board index found that 30% of incoming S&P 500 directors were active or retired CEOs, 59% of new appointees were retired, and average director pay was $336,352. Start with an advisory seat; how to become a board advisor covers getting the first one.

Short version: start with calls and one project, and treat a board seat as a long-term goal.

2. Use your knowledge while it is fresh

In our view, your value to buyers drops as your last role gets older. Buyers pay for how things work now: which vendors win, what prices look like, who approves a purchase. That knowledge is most specific right after you leave, so three habits help:

Start in the first months, not after a year off.
Put dates on everything. List the years of each role and the specific systems, vendors and markets you handled. GLG says to keep your profile up to date to be matched to more projects.
Stay close to the topic. An advisory seat, an industry group or occasional project work keeps your view current enough to sell.

Retirement also removes one hurdle. GLG's member programs page says enrollment normally needs confirmation from your employer's HR or legal team, but that people who are self-employed, retired or working independently may be enrolled automatically.

3. Check what you still owe your former employer

Retiring does not end your confidentiality obligations, and it may not end a non-compete. Read three documents before you take paid work: your original employment agreement, any separation or retirement agreement, and the terms of any equity or deferred pay you still hold. Look for confidentiality, non-compete, non-solicitation and any clause that ties continuing payments to staying out of competition.

Non-compete law depends on your state. The federal rule that would have banned most non-competes is gone: on September 5, 2025, the FTC voted to dismiss its appeals and accept a court ruling that it lacked authority to issue the rule. Some states go further on their own. California's Business and Professions Code section 16600 voids contracts that restrain anyone from a lawful profession, trade or business, with narrow exceptions. This is not legal advice; a short review by an employment lawyer is cheap next to a dispute with a former employer.

Confidentiality has no state-by-state escape. You can sell your judgment about how an industry works. You cannot sell your former employer's numbers, customer terms or plans. If you were an officer of a public company, be especially careful with anything that has not been announced; the post on material non-public information explains why.

4. Price by the project, and charge more than your old salary per hour

Your old salary per hour is a floor, because your employer also paid for your benefits and payroll taxes. For a broad benchmark, BLS reports a May 2025 median of $48.97 an hour for management analysts, often called management consultants; a retired executive with a specific track record should price well above that median.

Here is a made-up example. Margaret retired last spring as vice president of operations at a regional hospital system, after leading its move to a new supply contract. A private equity firm asks for help reviewing a similar contract at a hospital it plans to buy. Margaret quotes a fixed fee for a two-week review and a written memo, plus a separate hourly rate for any follow-up calls. A fixed fee protects her from scope creep and makes the yes easy for the buyer.

The consulting rate calculator turns a target income into an hourly rate, a day rate and a project price. Put the scope and fee in a short consulting agreement.

Consulting income can reduce Social Security benefits taken before full retirement age. The Social Security Administration's page on receiving benefits while working sets these limits for 2026:

Under full retirement age all year: Social Security deducts $1 from benefits for every $2 you earn above $24,480.
The year you reach full retirement age: it deducts $1 for every $3 above $65,160, counting only earnings before the month you reach that age.
From the month you reach full retirement age: there is no limit, and Social Security recalculates your benefit to credit the months it withheld.

For self-employed people, the test counts your net profit, not your gross fees. It does not count pensions, annuities, investment income or interest. The same page says that if a year of earnings is one of your highest, Social Security recalculates your benefit and pays any increase.

If you plan to consult heavily before full retirement age, compare the deduction with the fees. Sometimes the right answer is to delay claiming.

6. Pay self-employment tax and estimated tax, at any age

Consulting income is usually self-employment income. The IRS self-employment tax rate is 15.3% (12.4% Social Security, 2.9% Medicare) on net earnings of $400 or more, and the IRS says the rules apply "no matter how old you are and even if you are already receiving Social Security or Medicare."

You generally have to pay estimated tax if you expect to owe $1,000 or more when you file. Publication 505 lists the 2026 due dates (April 15, June 15 and September 15, 2026, and January 15, 2027) and explains an easier route for retirees: have income tax withheld from Social Security benefits with Form W-4V, or from a pension with Form W-4P, and skip the quarterly payments.

Self-employment income also reopens retirement saving. A SEP IRA caps contributions at the lesser of 25% of compensation or $72,000 for 2026. That page states the limit in terms of an employee's pay, so ask an accountant to work out the figure for your own net earnings.

7. Watch your Medicare premium two years out

If you are on Medicare, consulting income can raise your premiums later. The 2026 standard Part B premium is $202.90 a month, according to CMS. Above $109,000 of modified adjusted gross income for a single filer, or $218,000 for a joint return, the premium rises in steps, starting at $284.10 a month.

Social Security's higher-income premium page says the 2026 amount generally uses your tax return for 2024. So a big consulting year shows up in your premiums two years later. The same page lets you ask for a new decision if your income has gone down because you stopped working or cut your hours, using Form SSA-44. If your last salary year is pushing up your premium now, file that form.

8. Get the first engagement from people who knew your work

Your first client is rarely a stranger. Tell former peers at non-competing companies, former suppliers and investors who know your work what you want: "two or three projects a year on hospital supply contracts" is easier to act on than "some consulting." Sign up with two or three expert networks while your last role is recent. Browse the board advisors, chief operating officers and chief financial officers directories to see how others with your background are described.

On Instant Expert, a buyer invites you to a specific paid call or a written or voice answer and sets the amount up front. You receive the full amount, or you can reply with your own higher price, and payment goes out about 24 hours after a call by direct deposit, gift card or a donation to a charity you pick. Claim your profile to set the rate buyers start from, or see open paid requests on the request board.
