Accurate day counts
Log trips once. easySED calculates UK vs non-UK days using the UK-midnight rule, so totals stay consistent.
Audit-ready evidence
Store travel proof and generate exportable “evidence packs” to support your SED position if HMRC asks.
365-day progress
See how far you are through your qualifying period, days remaining, and your projected day-365 date.
HMRC-ready exports
Auto-populate official templates (e.g., HMRC HS205-style supporting docs) with your tracked data.
