Commercial Pilots and Flight Crew Tax Guide 2026: Per Diem, Multi-State Filing & FEIE

KEY INSIGHT
Commercial pilots and flight attendants are W-2 employees whose primary tax issues are the per diem meal allowance, multi-state income allocation, and — for international route crews — the Foreign Earned Income Exclusion. Airlines typically pay per diem as a tax-free allowance to crew members away from their domicile base; if per diem paid by the employer is below the IRS limit, crew members historically could deduct the gap, but TCJA eliminated this for employees. International route pilots may qualify for FEIE if they meet the physical presence test. Crew members only file in their domicile state and certain states where they have nexus — not every state they layover in.

Key Facts

Per Diem for Aviation Crew Members
IRS Rev. Proc. 2019-48 sets per diem rates for transportation workers subject to DOT hours-of-service rules — including FAA-regulated flight crew. The rate: $69/day (continental US) for meals and incidental expenses (same as truck drivers). If your airline pays you per diem that does not exceed this IRS rate, the allowance is tax-free to you and not reported on your W-2. If the airline's per diem is below the IRS limit, pre-TCJA employees could deduct the gap. Post-TCJA: employees can no longer deduct unreimbursed employee expenses on Schedule A. The deduction was eliminated — only self-employed crew (rare) can still deduct. Many airlines have adjusted per diem to match or approach the IRS rate in response.
Multi-State Tax Filing for Pilots
Crew members file a full resident state return in their domicile state (where they live). They do NOT file in every state they lay over in. The nexus rule: a brief layover (overnight or less) while in transit generally does not create taxable nexus in that state. Most states follow the 'convenience of the employer' or 'days worked' threshold before requiring non-resident filing. States requiring non-resident filing for aviation crew: New York (if you work more than 14 days in NY or earn more than $1 million from NY employers) and California are the most aggressive. A pilot domiciled in Texas who flies through JFK occasionally is unlikely to have a NY filing obligation. Keep records of days physically worked at departure airports vs in-flight.
FEIE for International Route Pilots
Pilots and flight attendants on international routes may qualify for the Foreign Earned Income Exclusion (FEIE) if they meet the Physical Presence Test: 330 full days outside the US in any 12-month period. For crew members flying international routes, qualifying depends on their specific schedule. If qualified: up to $132,900 (2025) of foreign-sourced earned income is excluded from US tax. 'Foreign-sourced' for flight crew: typically the portion of compensation attributable to time spent in international airspace and over foreign countries. IRS guidance on source allocation for crew is complex — some take the position that all compensation from international routes qualifies; others allocate by flight-hours or duty days. Consult a pilot-specialist CPA.
Deductible Expenses for Flight Crew
Post-TCJA, W-2 employees cannot deduct unreimbursed employee business expenses. However, many airline-related expenses may be deductible if: (1) your airline has an accountable plan and you are not reimbursed (deduct the gap pre-TCJA — no longer available); (2) you are a contract/freelance crew member (self-employed on Schedule C); or (3) the TCJA is extended/reformed. Union dues: ALPA (Air Line Pilots Association), AFA (Association of Flight Attendants) — not deductible by W-2 employees post-TCJA. FAA medical certificate fees: not deductible for employees post-TCJA. Flight training for initial license acquisition: not deductible (new profession). Flight training to maintain current certificates: was deductible pre-TCJA; not for employees post-TCJA.
Domicile and the Airline Tax Home Issue
Tax home for flight crew: the IRS has historically ruled that a flight crew member's tax home is their airline domicile base (the base they are assigned to), not necessarily where they live. This is significant: a pilot who lives in Phoenix but is domiciled at JFK cannot claim 'away from home' expenses (per diem, hotel) when spending time in New York for duty purposes — New York IS their tax home. To deduct transportation between home and domicile: it's a non-deductible commute. Many crew members 'commute' from their home state to their base state — this is a tax and lifestyle issue that catches many new hires off guard. Pilots who successfully establish their home state as their tax home (living near their base) have cleaner deduction situations.
Introduction

Commercial pilots and flight attendants have one of the more complex tax situations among W-2 employees — combining multi-state income allocation, per diem rules, and for international routes, potential FEIE eligibility. Airlines employ crew members at specific domicile bases (crew bases), and the tax treatment of their away-from-home expenses, union dues, and income depends significantly on how the airline structures compensation. TCJA (2018) eliminated the ability for employees to deduct unreimbursed business expenses, which previously allowed crew members to deduct per diem gap amounts, uniform costs, and other out-of-pocket expenses — this was a meaningful change for aviation workers.

Section 01

Part 121 vs Part 135 Tax Differences

Part 121 (major commercial airlines — United, Delta, American, Southwest) crew members are W-2 employees with the limitations post-TCJA described above. Part 135 (charter, corporate, on-demand air carriers) crew members may be independent contractors (1099) if structured as such, giving them access to Schedule C deductions:

Schedule C advantages for Part 135 contractors: Per diem deductible at full DOT rate; uniforms and professional clothing deductible; FAA medical certificate fees deductible; flight training to maintain certificates deductible; home office deductible if used regularly for scheduling, dispatching, or administration; vehicle mileage to airports deductible; union dues deductible; equipment (headsets, tablets, EFB subscriptions) deductible.

SE tax exposure: Self-employed Part 135 pilots pay 15.3% SE tax on net income. S-corp election applies if earning $40,000+ net. The deduction advantages must be weighed against the SE tax cost vs. W-2 FICA split.

FAQ

Frequently Asked Questions

Do I owe taxes in every state I fly through?

Almost certainly not. Flying through a state (brief stop, connection, layover) does not trigger income tax obligations in that state. Most states require either a minimum number of days worked in the state or a significant portion of duties performed there before filing is required. For commercial flight crew, the 'working' location is primarily considered to be the originating and destination airports, with in-flight time treated as occurring in the air or the employee's domicile state jurisdiction. New York is the most aggressive state — but even NY's rules are based on days worked at a fixed New York location, not just passing through airspace. California also pursues flight crew income. For most pilots, only their domicile state and possibly the base state require returns.

Can I deduct my flight simulator time or recurrent training?

Pre-TCJA, yes — recurrent training required to maintain an existing pilot certificate was a deductible employee business expense. Post-TCJA (2018 onwards), W-2 airline employees cannot deduct employee business expenses including training costs not reimbursed by the employer. If your airline reimburses training under an accountable plan, no tax issue arises. If you pay out-of-pocket for recurrent training your airline does not cover, it is currently not deductible for W-2 employees. For self-employed (Part 135 contractors, independent pilots), training to maintain existing certificates remains deductible on Schedule C. This is an area where TCJA expiration (2026 sunset) would restore the deduction for employees — worth monitoring as tax law evolves.

How does the Foreign Earned Income Exclusion work for international flight crew?

The FEIE physical presence test requires 330 full days outside the US in a 12-month period. Full days = days when you are outside the US for the entire 24-hour period (midnight to midnight). Days of travel crossing the international dateline or partially in the US don't count as full days. For an international pilot, this test is demanding — most crews have periods of US domestic flying or time at home that interrupt the 330-day count. The bona fide foreign residence test (alternative to physical presence) is difficult for crew members who don't establish residence in a specific foreign country. Crew members based in a foreign domicile (e.g., a US pilot domiciled at London Heathrow for a carrier) have a stronger case. Work with a CPA who has experience specifically with international aviation crew FEIE claims.
