Marine Accounts

The UK seafarer's tax companion. Track sea days, snap receipts, complete your tax return and message your accountant — all from your phone.

Marine Accounts is the tax companion built specifically for seafarers. Whether you're a deck officer, engineer, or crew member on a commercial vessel, manage your entire tax return from your phone — on board or ashore.

Complete Your Tax Return Step by Step Work through your tax return at your own pace with a guided organiser. Nine clear sections cover sea-based earnings, land-based earnings, time outside the UK, other income, investments, rental property, SED declaration, bank statements and payslips, and a final sign-and-submit step with a digital signature pad. Track your progress as you go and pick up where you left off.

Track Your Sea Days Log your trips as they happen so your Seafarer's Earnings Deduction eligibility is always up to date. Record leave and return dates with notes, and never struggle to reconstruct trip history from memory again.

Scan Receipts Instantly Snap a photo of any receipt with your phone's camera. Details are extracted automatically and added to your expenses. Attach receipts to specific tax returns or MTD quarters, and organise them by category.

Making Tax Digital (MTD) View your quarterly MTD submissions, track deadlines with colour-coded alerts, add expenses to each quarter, and submit directly to Marine Accounts for filing.

Message Your Accountant Send and receive messages directly within the app. Attach documents, photos, and files to any conversation. Get push notifications when your accountant replies so you never miss an update.

Upload Documents Securely Upload bank statements, payslips, P60s, P45s, and other supporting documents straight from your phone. Use the camera, photo library, or file picker to attach PDFs, images, and office documents.

Manage Your Profile Keep your personal, employment, and tax details up to date in one place. Store your National Insurance number, UTR, vessel details, and contact preferences.

Connect with Employers & Crew Looking for your next role, or looking to crew your vessel? Create an employment search profile so employers can discover you, or browse crew profiles to find the right person for the job. Send an introduction and message directly within the app to discuss opportunities.

Refer a Friend Refer fellow seafarers to Marine Accounts for tax or mortgage services and track the status of your referrals.

Secure & Reliable Protect your account with Face ID or Touch ID. Your data is cached locally so key information remains accessible even when you're offline at sea, with automatic syncing when you're back online.

Payments Made Simple Pay for your tax return securely within the app via Stripe, with support for single returns and bundled Saver+ packages.
