This is for anyone planning to change tax residency who wants to avoid the errors that make a move fall apart under review.
Most failed residency moves come from treating tax residence as a paperwork exercise rather than a real change of life. People obtain a visa or residence permit but do not actually move their personal and economic centre of life. Authorities reconstruct the year from objective evidence, not declarations.
Where we stand
A residency move that survives scrutiny is about reality, not declarations. This guide names the common failures so you can avoid them — take coordinated advice for your specific facts.
Why do tax-residency moves go wrong?
Most failed residency moves come from treating tax residence as a paperwork exercise rather than a real change of life. People obtain a visa or residence permit but do not actually move their personal and economic centre of life. Authorities reconstruct the year from objective evidence, not declarations.
The seven common mistakes
| Mistake | Why it fails | Better approach |
|---|---|---|
| Counting only 183 days | Many countries use additional residence tests. | Review all domestic residence criteria, not just day count. |
| Keeping a fully available home in the old country | Available accommodation is a strong tie. | Sell, let on commercial terms or formally remove availability. |
| Leaving family behind | Family is a key vital-interest tie. | Plan family relocation or document separate residence. |
| Continuing to work remotely from the old country | Work location creates residence and PE risk. | Limit days and restructure work arrangements. |
| No evidence of a genuine move | Authorities need objective proof. | Keep leases, registrations, bills and decision records. |
| Ignoring exit tax and departure rules | Some countries tax unrealised gains. | Review exit-tax exposure before leaving. |
| Assuming one permit solves everything | Residence permits are not automatic tax answers. | Align permit, actual residence and treaty position. |
How to make a move defensible
A defensible move means you can show, with contemporaneous evidence, that your life has genuinely shifted. This includes where you sleep, where your family lives, where you work, where your bank accounts are used and where your personal and economic relationships are centred.
A practical evidence checklist
- Day-count calendar with supporting travel records.
- Lease or ownership evidence in the new country.
- Utility bills, bank statements and local registrations.
- School records for children and family documentation.
- Work contracts, board minutes and decision logs.
- Deregistration from the old country where applicable.
Where Bulgaria fits
Bulgaria can be a genuine base for people who live and work there, establish a home and move their personal and economic centre of life. Bulgarian residence permits and tax residence must be supported by real presence, accommodation and activity, not just a permit or company registration.
