How to Start Consulting in Your Former Field

After 25, 30, or 40 years in a field, you have something most younger workers lack: real judgment built on countless mistakes, projects, and customers. Consulting is the work of selling that judgment to people and companies that need it. Unlike a part-time job where you trade hours for an hourly rate, consulting pays for the value of your advice, which is often many times higher per hour. A retired nurse can consult on hospital workflow at $90 to $150 an hour. A retired accountant can review small-business books at $75 to $125 an hour. A retired teacher can train new teachers at $60 to $100 an hour. A retired plumber can inspect homes for buyers at $200 per inspection. The math works because clients pay for the experience packed into each hour, not the hour itself.

Starting a small consulting practice in 2026 takes less paperwork than most people fear. You do not need to incorporate a company on day one. You can begin as a sole proprietor with nothing more than a business name, a simple agreement form, and a free invoicing tool. The IRS treats sole-proprietor consulting income as self-employment, which means you report it on a Schedule C with your regular tax return and pay self-employment tax of about 15 percent on top of regular income tax. Many retired professionals add an LLC (Limited Liability Company) after their first year once income is steady, mostly for liability protection. The LLC paperwork costs about $100 to $300 in most states and takes about an hour to file online.

The most important early decision is your niche, meaning the narrow problem you solve. "Business consulting" is too broad. "Helping small medical practices write office policies that follow HIPAA rules" is narrow enough to be marketable. "Marketing consulting" is too broad. "Helping retirement-community newsletters increase reader response" is narrow enough. The narrower your niche, the higher your hourly rate, because clients pay specialists more than generalists. Spend a week thinking about which slice of your old career was the most enjoyable and most in demand, and write that down as your starting niche. You can always widen later.

Clients come from three places: people who already know you, referrals from those people, and professional networks (LinkedIn, industry associations, and trade groups). Your first three clients almost always come from people you worked with in the past five years. The hardest part is telling them you are open for consulting work. Once you do, the phone often rings within weeks. Pricing is the next worry for most retirees. As a starting point, take your final full-time salary, divide by 1,000, and use that as your hourly consulting rate. A retired professional who made $80,000 a year would charge $80 an hour. A retired professional who made $150,000 a year would charge $150 an hour. Most consultants raise their rate by 10 to 20 percent after their first six months once they see the demand. The steps below walk through the practical setup from name to first invoice.
