TAX PLANNING PHILOSOPHY

Understanding Tax as Strategic Value Creation

TAX PLANNING FUNDAMENTALS

WHY TAX PLANNING MATTERS:
☐ Preserves value for shareholders
☐ R&D credits can be significant
☐ Exit planning requires early setup
☐ Multi-state complexity grows fast
☐ Compliance failures are costly

CEO'S ROLE IN TAX:
☐ Ensure proper entity structure
☐ Understand key tax benefits (QSBS, R&D)
☐ Oversee compliance
☐ Plan early for exits
☐ Work with qualified tax advisors

THE TAX REALITY:
"Tax planning isn't about avoidance—it's
about structuring properly to capture
benefits you're entitled to. Poor planning
can cost millions at exit."

TAX PLANNING TIMELINE:
Before founding: Entity structure, state selection
At founding: QSBS setup, 83(b) elections
Growing: R&D credits, state nexus
Pre-exit: QSBS verification, structure planning
At exit: Maximize after-tax proceeds

COMMON TAX MISTAKES:
☐ Wrong entity type (LLC vs C-Corp)
☐ Missing 83(b) election deadline
☐ Not claiming R&D credits
☐ Ignoring state nexus
☐ Not verifying QSBS qualification
☐ Poor exit structure planning

KEY TAX CONCEPTS FOR STARTUPS:
1. QSBS: Up to $10M tax-free gain per holder
2. R&D Credits: Offset payroll or income tax
3. 83(b) Election: Convert ordinary to cap gains
4. State Nexus: Where you owe state taxes
5. 409A Valuation: Required for option pricing
