TL;DR — Key Takeaways
- →Manual what-if tests check one idea at a time.
- →A calendar shows bookings. It does not rank the unused days by net pay.
- →Residency Router suggests the largest safe block per candidate country and waits for you to commit it.
- →It does not book flights or visas.
Short answer
If you already know the candidate countries, the useful planner is the one that sizes a legal stay in each and ranks them by what you would keep after tax.
Options
| Approach | What you get |
|---|---|
| Calendar or whiteboard | Dates you typed, no tax rank, no 90/180 check unless you do it separately |
| One-off what-if | One hypothetical against the current log |
| Domicyle Residency Router | Largest safe block per candidate, Schengen and residency thresholds, ranked by projected net income, added to the log only after you commit |
Booked trips stay in the log and constrain the next suggestion. A plan that would create a dual-residency question is shown with a warning.
Educational planning only — not tax or immigration advice.
