Day thresholds are useful but never enough to calculate personal tax. Vietnam, Indonesia and Malaysia have other qualifying tests; Thailand also taxes certain Thai-source income.
| Destination | Headline day threshold | Important exception or alternative | Full guide |
|---|---|---|---|
| Thailand | 180 days in tax year | The Revenue Department's older English overview uses 'more than 180 days' in one location, while the current section 41 wording and the 2024 explanatory guidance say '180 days or more'. Do not rely on an unverified one-day shortcut. | Explore ↗ |
| Vietnam | 183 days + residence rules | Vietnam's Law 109/2025/QH15 came into force on 1 July 2026; specified income-tax provisions for salaries and business income relate to the 2026 tax year. A guide using only the earlier seven-bracket system may be stale. | Explore ↗ |
| Bali / Indonesia | More than 183 days in 12 months | A limited four-tax-year treatment for certain qualifying foreign experts with specific skills does not create a blanket exemption for all expatriates or all remote workers. Eligibility and the source of income must be carefully verified. | Explore ↗ |
| Malaysia | 182 days + linked periods | Foreign source and Malaysian source are not decided solely by who pays a salary. Employment physically exercised in Malaysia and treaty claims may need distinct treatment, including LHDN's 2026 ruling for foreign nationals. | Explore ↗ |
In-depth tax guides by country.
Thailand
A Thailand income-tax review should separate the tax residence year, earnings date, actual source, date and nature of transfers, and possible treaty relief.

For Vietnam, check the calendar year and first-arrival period, registered or rented accommodation, where work is physically performed, payer and employer arrangements, tax withholding and year-specific rules.
Explore this tax cluster ↗6 ARTICLESBali / Indonesia
For Bali, track rolling presence days, whether there is a long-term home or intention to reside, actual location of work, income types and the taxpayer's registration/reporting position.
Explore this tax cluster ↗6 ARTICLESMalaysia
For Malaysia, check Section 7 residence tests, source of each earning, whether foreign income qualifies for conditional exemption, documentary proof and appropriate return forms.
Explore this tax cluster ↗Tax residence is not the same as immigration residence
A visa, an apartment lease and a number of days are different forms of evidence. An employment contract may affect income sourcing; pensions and dividends can follow separate treaty provisions. You can meet more than one domestic residence definition and may then need a treaty analysis.
Do not compare tax rates without a common fact pattern
For a meaningful comparison, record where services are physically performed, each income category and source, taxes already paid, your entry dates, home-country obligations and whether foreign earnings are received in your destination. A high marginal rate is not an effective rate and a foreign-income exemption is not the same as all income being untaxed.

A qualified adviser should review residence, income source, foreign tax, treaties and your documents before you file. Cost of Asia does not promise a match or tax outcome.
