Australian Tax Intelligence

Tax knowledge system for Harry's multi-entity business with automatic knowledge building via Graphiti (facts) and Serena (patterns).

When to Use This Skill

Automatically activate when user mentions:

Tax concepts: deduction, write-off, tax bracket, franking credits, BAS
GST: threshold, registration, turnover, compliance
Entities: MOKAI, MOK HOUSE, SAFIA, Family Trust, sole trader
Income: APRA royalties, salary, dividend, distributions
Assets: Tesla, home office, musical instruments
Questions: "Is X deductible?", "What's my tax on Y?", "Should I register for GST?"

Knowledge Architecture (Three-Layer System)

Layer 1: Entity Facts & Relationships → Graphiti MCP

What Graphiti stores:

Entity ownership (Harry owns MOK HOUSE → transferring to HS Family Trust)
Asset details (Tesla loan $90,254 @ 4.23%, balloon $41,676.82 Dec 2026)
Deduction rules (Gym: NEVER deductible, Instruments: YES deductible)
Financial events (SAFIA show $60K on [date], Invoice overdue since [date])
Income thresholds (Harry target <$45K for 19% bracket)

Query pattern:

mcp__graphiti__search_memory_facts({
  query: "[entity/asset/income] tax deductible rules ownership"
})

Layer 2: Calculation Methods & Patterns → Serena MCP

What Serena stores:

Deduction calculation methods (Logbook vs cents/km for vehicles)
Database schema (Supabase column names, table relationships)
File locations (Financial reports → 01-areas/finance/analysis/)
Workflow patterns (Cash flow: 3-month rolling average for APRA)
Tax strategies (Distribute to Wife first to minimize 32.5% bracket)

Query pattern:

mcp__serena__read_memory({
  memory_file_name: "harry_tax_deduction_patterns"
})

Layer 3: Tax Law & Rates → Skill Reference Files

What skill provides:

Australian tax rates (FY2025-26 brackets)
GST rules (threshold $75K, registration timing)
Company/trust tax rates (25% base rate entity, 45% accumulation)
General deduction principles (Section 8-1 ITAA 1997)

Load pattern: Reference files on-demand only

Core Workflows

Workflow 1: Deduction Validation

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

Steps:

Check Graphiti first (instant answer if rule exists):

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

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?

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

mcp__serena__read_memory({
  memory_file_name: "harry_tax_deduction_patterns"
})

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.]

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"
})

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:

Query Graphiti for current status:

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

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
}

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)

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:

Query Graphiti for income data:

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

Query Serena for distribution strategy:

mcp__serena__read_memory({
  memory_file_name: "harry_tax_deduction_patterns"
})

Calculate tax scenarios:

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

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

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
