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. ## Is Seafarers Tax Auto Log safe?

Validation: • Xcode build passes. • Live diagnostics intermittently failed from Xcode’s source editor service, but full builds are clean. ### 1.4 — 2026-08-22 Changed in this pass: • Updated HS205Calculator so periods close as soon as they qualify or fail. • Added gap-banking logic: if a period reaches 365 during a UK gap, it closes on that exact day. • Added shared daysInHand(total:ukDays:) logic using total - 2×UK. • Updated dashboard period totals so banked UK waiting days are included in closed-period totals. • Updated PDF export to export one period, not a continuous all-voyages table. • Wired “Make Claim — Export HS205 PDF” to export the tapped period. • Added a final UK-waiting row in the PDF when a period qualifies during a gap. • Fixed PDF days-in-hand label/calculation to E − 2×G. • Excluded future/planned voyages from export math. • Improved import duplicate handling so same departure/return dates are skipped/merged instead of duplicated. • Fixed auto-tracked duplicate date comparison by comparing day-start dates. • Removed unused .inProgress. • Removed dead “depart date passed” UI branch. • Added a regression test for Kevin’s real 18-voyage log and expected dashboard totals. ### 1.3 — 2026-08-09 Fixed the Edit button on manually-added voyages Replaced the cramped inline "Delete? Yes/No" on a voyage Replaced the period tab's tiny × delete ### 1.2.1 — 2026-08-01 Location bug fix ### 1.2 — 2026-07-28 Days in hand rollover bug fix ## More apps by Kevin Tough - [WantWithMe](https://appshunter.io/ios/app/wantwithme/id6804046799) All apps by Kevin Tough: https://appshunter.io/developer/1896536746 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
