File your 2026 U.S. taxes with a marine-focused specialist.
Work with a team that understands crew contracts, foreign flags, daywork, FX, and refit seasons. Your 1040 or business return is prepared with a marine lens, from the first intake to final e-file.
How filing with MFS works
A clear, three-step process. Most clients complete onboarding in under fifteen minutes, even when they are offshore or between crossings.
Select “Start My 2026 Filing” to open your secure TaxDome portal. Complete a short intake so we understand your role, flags, days in the U.S., and income sources.
Upload W-2s, 1099s, contracts, payslips, FX statements, and boat account summaries. We translate your yachting year into clean numbers and a defensible filing position.
We prepare your return with a marine lens, review it with you in plain English, and handle e-file and copies for banks, visas, or lenders.

Crew referral program
A simple way to thank the crew who send other crew our way. No forms, no codes — just your name.
Most of our new clients come from recommendations on board, at the dock, or during a yard stay. The crew referral program makes sure you are recognised when you point someone towards MFS.
It is intentionally simple:
There is no cap on how many people you can refer. If you are often the person explaining U.S. taxes on board, this is a straightforward way to turn that into real value for you.
Questions clients ask before filing
Many of our clients are travelling, offshore, or operating businesses across time zones. They want to know that their filing position is defensible and that the process is organised.
This page is designed so you can decide quickly if MFS feels like the right fit. When you are ready, you can move straight into the portal and begin.
Do I need to log in before I see anything?
Yes. All 2026 tax work runs through your secure MFS portal, powered by TaxDome. Once you log in or create an account you will see your tasks, document requests, messages, and engagement letters in one place.
What if I am offshore or in a different time zone?
That is completely normal in our practice. Almost everything can be handled inside the portal and by secure messaging. When a call is necessary, we work around your watch schedule and time zone.
Someone told me crew do not pay U.S. tax if they are always on boats. Is that true?
Not necessarily. Whether you owe U.S. tax depends on citizenship, residency, days in the U.S., how your income is structured, and whether exclusions apply. We walk through those questions during intake so your position is documented.
Can you help if I have missed several years or received IRS letters?
Yes. Many clients come to us after one or more missed seasons or after receiving notices. We can combine prior-year returns with your 2026 filing and help you respond properly to IRS correspondence.
How does the crew referral program work?
If you are an MFS client and you refer another crew member who becomes a signed, paying tax client, you receive a $50 referral thank-you. Your referral simply needs to mention you on intake or in the portal so we can attribute the referral correctly. If you have several referrals, we track each one and apply the reward according to our referral policy.
