Report
Around the beginning of last year it seemed the level of service was declining, as Id been with Seatax for many years I stayed with them. Im glad to say that service is now back to where it was previously and my new advisor even has a WhatsApp contact to make it easier when Im away at sea with very limited communication.

I've used them for 30 years and were excellent. I left for another accountant who was excellent but retired and I went back to my old accountant at seatax who was still OK but she retired and the new accountant is slow to reply , rude and hopeless.

Report
I am employed by one of the big cruise lines, and first used Seatax back in 1994. Unfortunately the number of basic errors on my recent tax return would have cost me an additional 300 had I not made my own calculations. I was refunded my fee following my complaint, which I did not feel was managed competently. I have been advised by colleagues that the original Seatax team split and set up another tax advisor company in Doncaster (which they have recommended), and may explain the decline in Seatax attention to detail and service levels.

Very rude and unprofessional whilst on the phone. official documents lost in transit even though the post was packed with care and sent recorded too. Marine accounts are cheaper and more professional than this company and i would recommend future clients take these points into account when considering using this service.
