What Flags Tax Residency tracks

Flags: Tax Residency is an early-warning tracker for day counts, tax-year windows and selected ties. It is designed to make a potentially forgotten travel record visible before a threshold surprises you. It does not determine your tax residence; it helps you notice when the underlying facts deserve a closer look.

The record it helps you keep

The app can use photo information and manual confirmation to help you review stays. It compares the resulting record with the thresholds and tax-year windows it has been designed to surface. The important word is review: a suggested period needs to match the journey you actually made.

Use manual confirmation for gaps, trips without useful photos, or dates that need correcting. Keep the original documents you may need outside the app. A record can be valuable long before a tax question arises, because it gives you a starting point instead of a last-minute reconstruction.

What a warning means

A warning is a prompt to investigate, not a tax conclusion. Residence can depend on facts that a day tracker cannot prove: local legislation, a home, family, work, treaties, immigration status and special regimes can all matter. The relevant rule may use a different tax year or a broader test than a single count.

When a warning appears, check the dates behind it first. Then read the current official guidance for the jurisdiction and take advice when the decision could affect a return, move or work arrangement. The limits and scope guide explains why the final answer must go beyond the app.

Start with a reliable travel record

Review suggested stays, add missing days manually and retain the documents you need for formal advice. A short, regular review is generally easier than trying to remember a year of travel at once. Pay particular attention to arrival and departure dates, overlapping journeys and any period that will be close to a country-specific threshold.

For a practical checklist, read how to review your day record. Flags is an early-warning tool, not tax advice; confirm with a qualified adviser.
