Financial planning for people who don't stay in one tax year.
SyncSphere Financial Planning advises internationally mobile professionals on cross-border tax residency, retirement and investment planning — through structured advisory consultations and planning engagements run from our Bangkok office.
How a planning engagement runs, from first call to written plan
Every engagement follows the same four-stage sequence, whether you are relocating to Thailand, returning home, or managing income in two currencies. Locality shapes each stage — your tax-resident country drives the analysis, not a generic template.
Scoping call
A 30-minute conversation to understand where you are tax-resident today, where you plan to be next, and the decisions on the table — equity vesting, property, pension transfer, or a pending move.
Document and residency review
You share statements, tax filings and residency documents through a secure intake. We map your Thai and home-country positions side by side, flagging conflicts before they cost you.
Written planning engagement
A fixed-scope planning engagement produces a written report: residency status, exposure areas, and prioritised actions for the next 12 months and the next five years.
Advisory follow-up
Follow-up advisory consultations track implementation, refresh the plan after a relocation or a change in income, and keep the cross-border picture current.

The areas a mobile professional actually faces
Advisory consultations are scoped to the questions that come with moving across tax systems. We do not sell products on commission; engagements are fee-only, and the scope and price are fixed in a written agreement before work begins.
- Thai tax residency and the 180-day rule, set against your home-country residency
- Cross-border income timing — salary, bonuses, equity vesting and rental income
- Pension and provident fund treatment when you leave or arrive in Thailand
- Retirement and investment planning in THB and a second currency
- Remittance planning for funds brought into Thailand

Planned from Bangkok, written for the move
Thailand taxes residents on worldwide income; many home countries do the same on residency. That overlap is where mobile professionals lose money without realising it. Our engagements start from the Thai side of that overlap and work outward — so a plan written here holds when you file back home.
Who an engagement is for — and who it is not
A clear fit check saves everyone time. These three markers tell you whether a SyncSphere engagement will help, or whether another adviser is the better call.
It fits if you are moving, or have moved
You hold residency in one country and income or assets in another — a seconded executive, a returning professional, a founder splitting the year between Bangkok and elsewhere.
It fits if you want a written plan, not a product
You want a fee-only report with prioritised actions, not a commission-led investment sale. Engagements are scoped and priced before work begins.
It is not a fit for one-off tax filing
If you only need an annual Thai tax return filed, a local tax accountant is faster and cheaper. We can refer you to one — and take on the planning layer when you need it.
