## Frequently Asked Questions

### How long does it take to break even on the Lisbon relocation costs?
For an individual earning £120,000 with a £2,000 monthly rent differential, the £4,500+ upfront visa and setup costs are fully recovered within 14 to 18 months purely through housing and tax savings.

### What happens if UK tax residency is accidentally triggered while maintaining a London base?
Failing the Statutory Residence Test by spending more than 90 to 183 days in the UK can result in dual tax liability, negating anticipated foreign tax advantages and incurring retrospective HMRC penalties.

### Does Lisbon offer comparable professional networking to London?
While Lisbon has rapidly grown into a prominent tech and remote worker hub, it lacks the deep institutional capital, venture funding density, and enterprise clientele found in central London.
