Core Workflows

Workflow 1: Deduction Validation

User asks: "Is [expense] tax deductible?"

Steps:

1. Check Graphiti first (instant answer if rule exists):

   mcp__graphiti__search_memory_facts({
     query: "[expense] tax deductible Harry business"
   })
   

2. If no rule in Graphiti, apply general tax principles:

   • Section 8-1: Incurred in gaining/producing assessable income?
   • Nexus to income-producing activity?
   • Not capital, private, or domestic?

3. Validate against known patterns (from Serena if complex calculation):

   mcp__serena__read_memory({
     memory_file_name: "harry_tax_deduction_patterns"
   })
   

4. Provide answer with reasoning:

   ✅/❌ [Expense] is/is not tax deductible
   
   **Reasoning**: [Why based on tax law + Harry's situation]
   **Category**: [Expense type]
   **Apportionment**: [If partial, show %]
   **Evidence required**: [Receipt, logbook, etc.]
   

5. Store new rule (automatic):

   // Store in Graphiti for instant future lookup
   mcp__graphiti__add_memory({
     name: "Deduction Rule Discovery",
     episode_body: "[Expense] is [deductible/not deductible] because [reason]",
     source: "message",
     group_id: "harry-financial-entities"
   })
   

6. Suggest pattern (if recurring expense type):

   💡 **Pattern detected**: This expense type appears regularly.
   
   Should I store the calculation method in Serena?
   - Pattern: "[Expense category] → [Deduction method]"
   - Future benefit: Instant validation without re-analysis

See: workflows/deduction-validation.md for detailed workflow

Workflow 2: GST Threshold Monitoring

User mentions: entity name, turnover, GST registration

Steps:

1. Query Graphiti for current status:

   mcp__graphiti__search_memory_facts({
     query: "[entity] GST registered turnover threshold FY2025-26"
   })
   

2. Calculate threshold percentage:

   python scripts/validate_gst_threshold.py [current_turnover]
   

   Returns:

   {
     "current_turnover": 52000,
     "threshold": 75000,
     "percentage": 69.3,
     "should_alert": false,
     "recommendation": null
   }
   

3. If >70% threshold:

   ⚠️ **GST Threshold Alert**
   
   **Entity**: [Name]
   **Progress**: 69.3% of $75,000 threshold
   **Current turnover**: $52,000 (FY2025-26)
   
   **Recommendations**:
   - Monitor monthly turnover closely
   - Project annual turnover based on current rate
   - Register for GST if projection indicates threshold breach
   - Prepare for GST obligations (pricing, invoicing, BAS)
   

4. Store status in Graphiti:

   mcp__graphiti__add_memory({
     name: "GST Threshold Update",
     episode_body: "[Entity] turnover $52K (69.3% of threshold) as at [date]",
     source: "message",
     group_id: "harry-financial-entities"
   })
   

See: workflows/gst-threshold-check.md for monitoring schedule

Workflow 3: Trust Distribution Optimization

User asks: "Optimize trust distributions" or "What's best tax structure?"

Steps:

1. Query Graphiti for income data:

   mcp__graphiti__search_memory_facts({
     query: "Harry Wife income FY2025-26 salary APRA SAFIA"
   })
   

2. Query Serena for distribution strategy:

   mcp__serena__read_memory({
     memory_file_name: "harry_tax_deduction_patterns"
   })
   

3. Calculate tax scenarios:

   python scripts/optimize_trust_distribution.py \
     --harry-income 35000 \
     --wife-income 48000 \
     --trust-income 40000
   

4. Present optimization:

   ## Trust Distribution Analysis
   
   ### Current Structure (No Trust Distribution)
   - Harry: $35K APRA + $0 MOK HOUSE = $35K → Tax: $3,420
   - Wife: $48K employment → Tax: $7,020
   - **Total family tax**: $10,440
   
   ### Optimized (With Trust Distribution)
   - Harry: $35K APRA + $10K trust = $45K → Tax: $5,520
   - Wife: $48K employment + $0 trust = $48K → Tax: $7,020
   - Trust distributes: $40K (Wife $30K, Harry $10K)
   - **Total family tax**: $12,540
   
   ### Analysis
   ⚠️ Trust distribution increases tax by $2,100 in this scenario
   
   **Reason**: Both already in 19% bracket, trust income pushes toward 32.5%
   **Better strategy**: Retain income in company, pay when beneficial
   

5. Store strategy in Serena (if user confirms):

   mcp__serena__write_memory({
     memory_name: "harry_tax_deduction_patterns",
     content: "## Trust Distribution Strategy\n\n..." // Append pattern
   })
   

See: workflows/trust-optimization.md for calculation method
