Let's calculate the tax for an individual earning $3,000 USD per month (or $36,000 annually) in Vietnam, Japan, and the United States, based on their respective tax brackets:
1. Vietnam
Given the progressive tax brackets, here's how the tax would be calculated for an annual income of $36,000 USD:
- 5% for income up to 5 million VND (~$215) per month: 5% of $215 = $10.75
- 10% for income from 5 to 10 million VND (~$215 to $430) per month: 10% of $215 = $21.5
- 15% for income from 10 to 18 million VND (~$430 to $774) per month: 15% of $344 = $51.6
- 20% for income from 18 to 32 million VND (~$774 to $1,376) per month: 20% of $602 = $120.4
- 25% for income from 32 to 52 million VND (~$1,376 to $2,236) per month: 25% of $860 = $215
- 30% for the part of the income above 52 million VND per month, but here only up to $3,000 monthly, so approximately $764 is taxed at 30% = $229.2
Total monthly tax = $10.75 + $21.5 + $51.6 + $120.4 + $215 + $229.2 = $648.45 per month
2. Japan
For an annual income of $36,000 USD in Japan, converting to JPY gives approximately 4,680,000 JPY:
- 5% for income up to 1,950,000 JPY: 5% of $15,000 = $750
- 10% for income from 1,950,000 to 3,300,000 JPY: 10% of $13,000 = $1,300
- 20% for the remaining part of the income (4,680,000 JPY - 3,300,000 JPY) = 1,380,000 JPY, which is approximately $10,608, taxed at 20% = $2,121.6
Total annual tax = $750 + $1,300 + $2,121.6 = $4,171.6
3. United States
For an annual income of $36,000 USD:
- 10% for income up to $11,000: 10% of $11,000 = $1,100
- 12% for income over $11,000 to $44,725 (remaining $25,000 of $36,000): 12% of $25,000 = $3,000
Total annual tax = $1,100 + $3,000 = $4,100
Summary
- Vietnam: $648.45 per month (approximately $7,781.4 annually)
- Japan: $4,171.6 annually
- United States: $4,100 annually
These calculations are based on simple application of the tax brackets without considering other deductions or allowances that may apply in each country.
