Seafarers Tax Auto Log app analytics for October 9

Seafarer Tax Deduction helps UK seafarers track time spent outside the UK to qualify for the Seafarers' Earnings Deduction (SED) under HMRC HS205. Working out whether you meet the "50% rule" across a long qualifying period is fiddly and easy to get wrong. This app does the counting for you — logging your voyages, tracking your days in and out of the UK, and showing at a glance whether you're still qualifying. KEY FEATURES • Live qualifying tracker — see your days outside the UK, UK days used, and whether you're on track, updated automatically. • "Must depart by" date — the app tells you the latest date you can stay in the UK before breaching the 50% threshold, with reminders at 14, 7, and 3 days before. • Automatic voyage tracking — optional GPS logging records your position once per day and flags border crossings. Every record stays a draft until you review and approve it. • Multiple qualifying periods — track separate periods side by side and switch between them instantly. • Attach documents — keep discharge books, contracts, and payslips attached to each voyage as photos or PDFs. • Import & export — bring in voyages from a spreadsheet, and export your full log as CSV or XLS to send straight to your accountant. • HS205 working sheet — generate a PDF summary aligned to the HMRC HS205 format. Your data stays on your device. No account required. IMPORTANT This app is a tracking and guidance tool only. It does not provide tax advice and does not guarantee eligibility for the Seafarers' Earnings Deduction. Always consult a qualified tax professional or HMRC before submitting a claim.
