Legislative Change Monitoring Skill

Tracks changes to Australian tax legislation, ATO rulings, tax determinations, and court decisions that may affect the accuracy of tax analysis engines. Provides structured alerts when changes are detected that require engine updates, rate refreshes, or compliance recalculation.

When to Use

• Monitoring for new ATO tax rulings (TR) and tax determinations (TD) that affect engine logic
• Detecting federal budget announcements that change tax rates or thresholds
• Tracking Treasury Laws Amendment bills through Parliament
• Identifying court decisions (AAT, Federal Court, High Court) that change interpretation
• Alerting when Division 7A benchmark rate is published for the new FY
• Detecting changes to R&D Tax Incentive eligibility criteria
• Monitoring state government changes to payroll tax rates/thresholds

Monitoring Process

1. Scrape Sources
   ├── Use Jina AI Reader for ATO/government pages
   ├── Compare page content against last scrape
   └── Detect new items (rulings, determinations, bills)

2. Classify Change
   ├── Category 1: Rate change → immediate cache invalidation
   ├── Category 2: Rule change → engine update required
   └── Category 3: Deadline change → calendar update

3. Assess Impact
   ├── Which engines are affected?
   ├── Which financial years?
   ├── Which entity types?
   └── How many active analyses need re-running?

4. Generate Alert
   ├── CRITICAL: Immediate rate change affecting live calculations
   ├── HIGH: Rule change requiring engine update within 7 days
   ├── MEDIUM: Upcoming change (bill before Parliament)
   └── INFO: Professional guidance or interpretation update

5. Trigger Actions
   ├── Rate change → rate-change-monitor agent
   ├── Rule change → Linear issue for engine update
   ├── Deadline change → compliance-calendar-agent
   └── All → Log in legislative change register

Best Practices

• Scrape conservatively — respect rate limits on government websites (max 1 req/10s)
• Cache page content — compare against cached version to detect changes, not re-scrape blindly
• Verify before acting — rate changes should be confirmed from the official source (ATO Legal Database)
• Log all changes — maintain a legislative change register for audit trail
• Distinguish enacted vs proposed — bills before Parliament are NOT law until Royal Assent
• Monitor court appeals — a Federal Court decision may be overturned on appeal to Full Federal Court or High Court
• Include effective date — changes may be announced months before they take effect
• Cross-reference — verify ATO rulings against primary legislation (rulings can be withdrawn)
