About this skill
Tax residency thresholds are high-stakes numbers. A single day error can flip an employee from a 13% tax bracket to 30%, creating massive retroactive liabilities. This skill automates the calculation of qualifying days for cross-border and relocated staff, replacing error-prone manual spreadsheets with a systematic compliance engine.
What it does
- Qualifying Day Counting calculates total days spent in a jurisdiction within rolling 12-month or calendar-year windows.
- Threshold Guarding triggers automated warnings at 150 days and alerts at 170 days to prevent accidental residency shifts.
- Jurisdiction Logic applies specific rules for Russia (rolling 12 months), EU (calendar year), and US (substantial presence test).
- Retroactive Risk Auditing identifies prior periods where residency was misclassified, flagging potential tax exposure.
- Privacy Enforcement masks all personal identifiers, processing only date ranges and anonymized IDs.
How it works
- Input Context by providing the source/destination jurisdictions and the specific residency rule to apply.
- Provide Data via a masked CSV or JSON file containing arrival and departure dates linked to anonymized employee IDs.
- Execute Calculation to determine day counts and check against the 183-day threshold.
- Review Report which outputs a categorical compliance signal and a JSON risk assessment.
Frameworks & tools
The skill is designed for local execution within Claude Code, Cursor, or GitHub Copilot. It operates entirely offline without network access, ensuring payroll and travel data stays within your local environment.
Why this beats prompting it yourself
Writing a manual prompt for complex date arithmetic often leads to "off-by-one" errors or ignored leap years. This skill enforces strict jurisdiction-specific counting logic and privacy guardrails that a generic prompt lacks.
Use cases
- Monitoring relocated employees to prevent unexpected tax residency triggers.
- Auditing annual travel records before year-end payroll closure.
- Assessing retroactive tax risks for cross-border teams during M&A due diligence.
Known limitations
The skill produces categorical compliance signals, not final tax calculations or legal opinions. It requires pre-masked data inputs to maintain privacy compliance.
