What Marine Accounts does
Marine Accounts Ltd. is a UK-based specialist tax accounting firm headquartered in Whitstable, England, focused exclusively on seafarers, yacht crew, and marine professionals operating across multiple tax jurisdictions. Founded in 2013 by Patrick Maflin — a former yacht engineer, captain and Volvo Ocean Race manager with 14 years of maritime experience — the firm was built to address the specific financial and tax complexity faced by mobile maritime workers, including Seafarers Earnings Deduction (SED) claims, residency determination, and multi-country filing with HMRC, ATO, IRD, IRS and equivalent authorities.
The firm operates a web-based delivery model centred on a self-service portal for tax returns, a paperless document intake process, and several free online assessment tools (residency test for seven countries, SED qualifying test, seafarers tax days calculator). Core revenue is generated through fee-for-service tax return filings priced per country (£265 UK, £375 AUS/NZ, £600 France), tiered subscription packages (Saver+, MTD compliance at £249/quarter or £849/year, Premium concierge), tax consultation fees, and affiliate/referral revenue from marine insurance and a mortgage brokerage partnership. Distribution combines SEO-optimised content marketing, a blog archive running since 2015, social channels, a £50 referral programme, a 2024-launched mobile app, and physical presence at Mediterranean shipyards and marinas.
The customer base is highly fragmented, comprising individual seafarers and yacht crew as the primary personas, with a smaller secondary segment of marine professionals running limited companies requiring company tax returns. Geographic reach spans the United Kingdom, France, Ireland, Spain, Australia, New Zealand, the United States and South Africa. The firm is bootstrapped and founder-controlled (Company No. 09260348), with no disclosed external funding, M&A activity, or parent organisation.

Marine Accounts competitors and assessment
Company assessmentBroad incumbents
- H&R Block: Large global tax preparation firm offering online and assisted filing across multiple countries. Comparable in providing multi-jurisdiction personal tax-filing services at scale, including US expat/foreign-income scenarios (akin to Marine Accounts' FEIE offering).
- GoSimpleTax: UK online self-assessment tax software allowing individuals to file tax returns themselves. Comparable as a digital UK tax-filing channel serving the same HMRC self-assessment ecosystem, though without seafarer domain specialization.
- TurboTax (Intuit): Mass-market DIY tax software covering US returns including Foreign Earned Income Exclusion for Americans abroad. Comparable as a competing channel for US-citizen seafarers seeking to claim FEIE without using a specialized advisor.
- FreeTaxUK: UK tax return software and accountant-backed service for individuals filing HMRC self-assessments. Comparable in serving self-employed and high-earner UK taxpayers through a hybrid online/professional model.
- TaxCalc: UK tax software and practice solutions for accountants and individuals. Comparable as an established UK tax-filing platform competing for the same self-assessment customer pool, albeit at a broader, non-niche level.
Emerging players
- Taxfix: Consumer tax-filing app widely used in Europe, with a digital-first, chat-supported tax-return flow. Comparable in applying a mobile/digital product approach to personal tax filing for a mass-market audience.
- RIFT (Refund Investments For Taxation): UK tax-refund specialist helping individuals reclaim overpaid PAYE tax and similar reliefs. Comparable in operating a digital-first model focused on identifying and claiming specific UK tax reliefs for targeted worker segments.
Others
- Money Mover: Cross-border payments and financial services company targeting seafarers and marine professionals. Comparable as an adjacent financial-services provider serving the same seafarer/yacht-crew customer base with related banking and remittance needs.
