Expats struggle to determine correct tax residency and filing obligations across multiple countries with conflicting rules

Individuals working internationally (e.g., earning Hong Kong salary while staying in India) face complex, contradictory tax residency rules that vary by country and depend on specific thresholds like the 182-day rule. They lack clear guidance on which country's taxes apply, creating risk of double taxation, penalties, or unintentional non-compliance. Existing tax software and advisors often don't handle multi-country scenarios, forcing expats to piece together answers from forums.
