The independent CFI in the United States

What "independent" means legally

Under Part 61, your CFI certificate is the entire license to operate. No school certificate, no facility approval, no curriculum filing. You can take a student from first lesson to checkride solo endorsement in a rented 172, and the FAA is fine with that. Part 141 schools exist for structured-course benefits (lower hour minimums, VA funding, visa sponsorship), and their absence limits who you can serve, not what you can teach.

Worth knowing: when you give training without acting as pilot in command, for instance a flight review for a rated, current pilot flying their own airplane, you don't need a current medical to instruct. When you're PIC, which is most primary training, you do. BasicMed covers it.

Your TSA to-do list (yes, yours)

Since July 2024, the Flight Training Security Program covers every FAA flight training provider, and an independent CFI is a provider. This applies even if every student you ever teach is a U.S. citizen:

• Open a provider account on the FTSP portal (fts.tsa.dhs.gov).
• Complete TSA's security awareness training, with a refresher every 24 months. Put the due date somewhere that will actually remind you.
• Verify every student's citizenship before flight training starts. A U.S. passport or birth certificate works; the portal keeps the full list. The record you keep can be a logbook endorsement in your logbook and the student's: their full name, the document type and its number, the date, your signature and certificate number (49 CFR 1552.15(c)(2)). Keeping a copy of the document is allowed but never required. Keep the record five years.
• Training a non-citizen toward an initial certificate or an instrument, multiengine, or type rating? They need a TSA Determination of Eligibility first (their application, their fee, valid five years). You confirm it in the portal, notify TSA of the training event, and photograph the student on day one. Flight reviews, IPCs, ground training, and discovery flights trigger none of this.

TSA can inspect these records. Treat that sentence as the design brief for your filing system.

The paperwork that has to survive

Three record streams, all date-stamped, all signature-bearing, all with retention rules: the endorsements you give (solo, knowledge test, checkride, plus the newer MOSAIC set), the FTSP citizenship and training records above, and your own logbook entries backing the training you gave. A student will call you years later needing a copy of something. The instructors who can produce it in a minute keep students for life.

The business underneath

• Most independents run as sole proprietors: income and expenses on Schedule C, self-employment tax on the net, quarterly estimated payments to avoid a nasty April. An LLC changes liability posture, not taxes, unless you elect otherwise. A CPA pays for themselves the first year.
• Deductions live and die on records: mileage to the airport at the standard rate, headsets and iPads and charts, your own recurrent training. Log as you go; reconstruction in March satisfies nobody.
• Insurance before the first paid hour: CFI professional liability plus non-owned aircraft coverage. If you teach in a student's airplane, confirm their policy names instruction and covers you. "My insurer never asked" is how instructors discover exclusions.
• Get paid like a business: numbered invoices, receipts for cash and payment apps, income recorded the day it lands. Your tax return and any future loan application will both thank you.

Where the work is in 2026

• The 24-month heartbeat. Flight reviews and IPCs are the steadiest income in instruction, and every one is a relationship that renews on a schedule you can see coming.
• MOSAIC endorsements. Since late 2025, sport pilots can add retractable gear, constant-speed prop, and night privileges by one-time CFI endorsement, and a long list of legacy airplanes became sport-eligible. Transition training and checkouts for that fleet are a real, nameable product.
• BasicMed-freed pilots. Owners flying up to 12,500 pounds on a driver's-license medical, many stepping back into the left seat after years away. They want a patient instructor, not a school syllabus.
• The specialties schools don't staff. Tailwheel, mountain, seaplane, aerobatics, formation. Scarcity is the independent's pricing power.
