# Entity Structure Decision Framework

## Purpose

This recipe produces a clear entity structure recommendation — entity type, jurisdiction, formation tool, cost estimate, and step-by-step formation checklist — tailored to the founder's funding path, operating jurisdiction, and tax residency. The output replaces guesswork with a structured decision tree that accounts for VC requirements, tax optimization (QSBS, pass-through, 83(b) election timing), and cross-border implications.

## Prerequisites

- [ ] **Funding path decision** — VC-track, bootstrapped, or revenue-funded (even a directional answer is sufficient)
- [ ] **Founder tax residency** — country and state/province of tax residency for each founder
- [ ] **Operating jurisdiction** — where the company will primarily conduct business and hire employees
- [ ] **Budget for formation** — minimum $225 (US) to EUR 2,500 (Germany GmbH)
- [ ] **Legal counsel access** — recommended for multi-founder or cross-border setups (budget $1,500-$5,000)

## Constraints

- Delaware C-Corp is the only entity type acceptable to most US VC firms and accelerators (YC, a16z, Sequoia). LLCs create UBTI exposure for tax-exempt LPs. [src1]
- The 83(b) election deadline is 30 calendar days from restricted stock grant — missing it is irrecoverable and can cost founders hundreds of thousands in taxes. [src2]
- QSBS (Section 1202) provides up to $15M in capital gains exclusion for C-Corp stock held 5+ years. Filing 83(b) starts the QSBS clock at grant, not vesting — a 4-year acceleration. [src2] [src6]
- German GmbH/UG formation requires notarization by a German Notar — no DIY online path exists. [src4]
- UK Ltd formation fee increased to GBP 100 (from GBP 50) as of February 1, 2026. [src5]

## Tool Selection Decision

```
What funding path?
+-- VC / angel investment (any jurisdiction)
|   +-- US-based founders
|   |   +-- PATH A: Delaware C-Corp via Clerky or Stripe Atlas
|   +-- Non-US founders
|       +-- PATH B: Delaware C-Corp (flip structure) via Stripe Atlas + local entity
+-- Bootstrapped / revenue-funded
|   +-- US-based, < $80K annual profit expected
|   |   +-- PATH C: Single-member LLC (default tax) -- convert later if needed
|   +-- US-based, > $80K annual profit expected
|   |   +-- PATH D: LLC with S-Corp election
|   +-- UK-based
|   |   +-- PATH E: UK Ltd via Companies House
|   +-- Germany-based
|       +-- PATH F: UG (low capital) or GmbH (established)
+-- Undecided on funding
    +-- PATH C or E (preserve optionality, convert if VC path emerges)
```

| Path | Entity | Jurisdiction | Formation Cost | Annual Cost | VC-Compatible |
|------|--------|-------------|---------------|-------------|---------------|
| A: US VC Track | Delaware C-Corp | Delaware, US | $427-$819 | $225-$450/yr | Yes |
| B: Non-US VC Track | Delaware C-Corp + local entity | Delaware + home country | $500-$2,000 | $400-$1,500/yr | Yes |
| C: US Bootstrap | Single-member LLC | Home state, US | $50-$500 | $0-$800/yr | No (convert later) |
| D: US Revenue | LLC + S-Corp election | Home state, US | $50-$500 + $0 IRS filing | $0-$800/yr | No (convert later) |
| E: UK Bootstrap | Private Ltd (Ltd) | England & Wales | GBP 100-$200 | GBP 50/yr (confirmation) | Limited (UK VCs accept) |
| F: Germany | UG (min EUR 1) or GmbH (EUR 25K) | Germany | EUR 900-$2,500 | EUR 200-$500/yr | Limited (EU VCs accept) |

## Execution Flow

### Step 1: Determine Funding Path and Jurisdiction

**Duration**: 15-30 minutes
**Tool**: Decision worksheet

Answer these three questions to select your path from the decision tree above.

```
ENTITY SELECTION WORKSHEET
===========================

Q1: Will you seek VC or angel investment within 24 months?
    [ ] Yes  --> Must use C-Corp (Path A or B)
    [ ] No   --> LLC/Ltd/GmbH acceptable (Paths C-F)
    [ ] Maybe --> Start LLC/Ltd, budget $3K-$10K for later conversion

Q2: Where are the founders tax-resident?
    [ ] United States      --> Form in Delaware (C-Corp) or home state (LLC)
    [ ] United Kingdom     --> Form UK Ltd
    [ ] Germany            --> Form UG or GmbH
    [ ] Other EU country   --> Evaluate local entity + potential Delaware flip
    [ ] Multiple countries --> Need cross-border counsel

Q3: Expected annual profit within 2 years?
    [ ] <$0 (pre-revenue)    --> Tax structure is secondary to VC compatibility
    [ ] $0-$80K              --> Default LLC taxation is fine
    [ ] $80K+                --> S-Corp election saves 15.3% SE tax on distributions
    [ ] Unknown              --> Default to simplest entity for your jurisdiction

YOUR PATH: _____ (A / B / C / D / E / F)
```

**Verify**: The selected path matches both funding intent and founder residency. If any founder is non-US but the startup wants US VC, Path B is required.
**If failed**: If founders disagree on funding path, default to the entity that preserves the most optionality (LLC for US, Ltd for UK) and revisit in 6 months.

### Step 2: Form the Entity (Path A — Delaware C-Corp via Clerky/Atlas)

**Duration**: 30-60 minutes active, 1-3 business days processing
**Tool**: Clerky ($427-$819) or Stripe Atlas ($500)

This is the most common path. Use Clerky if you want modular legal documents for future fundraising. Use Stripe Atlas if you want an all-in-one bundle with banking. [src3] [src8]

```
FORMATION CHECKLIST — DELAWARE C-CORP
======================================

Pre-formation:
[ ] Choose company name (check availability: https://icis.corp.delaware.gov/ecorp/entitysearch/namesearch.aspx)
[ ] Decide authorized share count: 10,000,000 shares at $0.0001 par value (standard for VC-track)
[ ] Designate registered agent (included in Clerky/Atlas first year)

Via Clerky:
[ ] Create account at https://clerky.com
[ ] Select "Incorporation" package ($427) or "Company Lifetime" ($819)
[ ] Complete incorporation questionnaire (name, agent, shares, directors)
[ ] Clerky files Certificate of Incorporation with Delaware
[ ] Receive filed certificate (2-3 business days)
[ ] Complete post-incorporation setup: bylaws, board consent, stock issuance

Via Stripe Atlas:
[ ] Create account at https://stripe.com/atlas
[ ] Pay $500 one-time fee
[ ] Complete application (name, founders, address, shares)
[ ] Atlas files with Delaware (next-day expedited)
[ ] EIN obtained automatically
[ ] Founder equity issued + 83(b) election forms generated
[ ] Bank account opened (Stripe Treasury or partner bank)

Post-formation (BOTH paths):
[ ] Obtain EIN from IRS (Atlas does this automatically; Clerky: apply at https://www.irs.gov/businesses/small-businesses-self-employed/apply-for-an-employer-identification-number-ein-online)
[ ] Issue founder stock at par value ($0.0001/share)
[ ] FILE 83(b) ELECTION WITHIN 30 DAYS — mail to IRS + keep proof of mailing
[ ] Execute IP assignment agreements (all founders assign prior IP to company)
[ ] Adopt bylaws and initial board resolutions
[ ] Open business bank account
[ ] Register as foreign corporation in your operating state (if not Delaware)
```

**Verify**: Certificate of Incorporation received, EIN assigned, 83(b) election mailed with certified mail receipt, stock certificates or electronic records issued.
**If failed**: If name is rejected, Clerky/Atlas will notify — choose alternate name. If EIN application fails, call IRS at (800) 829-4933.

### Step 3: Form the Entity (Paths C/D — US LLC)

**Duration**: 30-60 minutes active, 1-14 days processing (varies by state)
**Tool**: State Secretary of State website or formation service

```
FORMATION CHECKLIST — US LLC
=============================

[ ] Choose state of formation (usually your home state)
    Common costs:
    - Wyoming:     $100 filing + $0 annual
    - Delaware:    $90 filing + $300/yr tax
    - California:  $70 filing + $800/yr franchise tax (minimum)
    - New York:    $200 filing + publication requirement ($500-$1,500)

[ ] File Articles of Organization with Secretary of State
[ ] Obtain EIN from IRS (https://www.irs.gov/ein)
[ ] Draft Operating Agreement (required for multi-member LLCs)
    - Define: ownership percentages, voting rights, profit distribution, exit terms
[ ] Open business bank account

FOR PATH D (S-Corp Election):
[ ] File IRS Form 2553 within 75 days of formation
[ ] Set up payroll for all member-employees
[ ] Pay reasonable salary before taking distributions
```

**Verify**: Articles of Organization filed, EIN received, operating agreement signed by all members. For Path D: Form 2553 acceptance letter from IRS.
**If failed**: If state rejects name, check name availability tool on Secretary of State website. If Form 2553 is late, file with reasonable cause explanation.

### Step 4: Form the Entity (Path E — UK Ltd)

**Duration**: 15-30 minutes active, typically same-day approval
**Tool**: Companies House online portal

```
FORMATION CHECKLIST — UK LTD
==============================

[ ] Choose company name (check: https://find-and-update.company-information.service.gov.uk/)
[ ] Register online at Companies House (https://www.gov.uk/limited-company-formation)
    - Fee: GBP 100 (digital) or GBP 124 (paper)
    - Need: registered office address (can use formation agent address)
    - Provide: director details, shareholder details, SIC codes
    - Articles of Association (Model Articles are fine for most startups)
[ ] Receive Certificate of Incorporation (usually same day for digital)
[ ] Register for Corporation Tax with HMRC (within 3 months)
[ ] Open business bank account (Tide, Revolut Business, or traditional bank)
[ ] Register for VAT if revenue will exceed GBP 90,000/yr
[ ] File annual Confirmation Statement (GBP 50/yr) [src5]
```

**Verify**: Certificate of Incorporation received with company number, Corporation Tax registration confirmed by HMRC.
**If failed**: Name rejection is the most common issue — Companies House provides instant feedback on name availability.

### Step 5: Form the Entity (Path F — German UG/GmbH)

**Duration**: 2-4 weeks (notary scheduling + Handelsregister processing)
**Tool**: German notary (Notar) + local Amtsgericht

```
FORMATION CHECKLIST — GERMAN UG/GMBH
======================================

UG (Unternehmergesellschaft) — "mini-GmbH":
[ ] Minimum share capital: EUR 1 (practical minimum EUR 1,000)
[ ] Draft Gesellschaftsvertrag (articles of association)
[ ] Book notary appointment (Notar) — mandatory, ~EUR 300-600
[ ] Notarize articles + shareholder resolutions at Notar
[ ] Deposit share capital into business bank account
[ ] Register at Handelsregister (commercial register) via Notar — ~EUR 150
[ ] Receive Handelsregister entry (2-4 weeks)
[ ] Register with Finanzamt (tax office) — Fragebogen zur steuerlichen Erfassung
[ ] Register with Gewerbeamt (trade office) if applicable — EUR 20-60
[ ] NOTE: UG must retain 25% of annual net profits until EUR 25,000 reserve reached [src4]

GmbH:
[ ] Same process as UG but minimum share capital EUR 25,000 (EUR 12,500 must be deposited at formation)
[ ] Higher formation costs: EUR 1,500-2,500 total (notary + registration)
[ ] No mandatory profit retention requirement
[ ] Higher credibility with German banks and business partners [src4]

CHOOSE UG vs GMBH:
  < EUR 25K available capital  --> UG
  EUR 25K+ available + need credibility --> GmbH
  Planning to convert UG to GmbH later --> start with UG, convert when reserves reach EUR 25K
```

**Verify**: Handelsregister entry confirmed, Finanzamt registration complete, business bank account active.
**If failed**: Notary scheduling can take 2-4 weeks in major cities (Berlin, Munich). Use online notary services (ride) for faster processing if available.

### Step 6: Post-Formation Tax Optimization (US C-Corp Only)

**Duration**: 1-2 hours
**Tool**: Tax advisor + IRS forms

```
POST-FORMATION TAX CHECKLIST — C-CORP
=======================================

83(b) ELECTION (CRITICAL — 30-DAY DEADLINE):
[ ] Complete IRS 83(b) election form for each founder
[ ] Mail to IRS within 30 days of stock purchase:
    Internal Revenue Service
    [Address for your region — see IRS.gov]
[ ] Send via certified mail with return receipt requested
[ ] Keep copy of: signed election, certified mail receipt, return receipt
[ ] Provide copy to company (corporate secretary)
[ ] Include copy with personal tax return for the year

QSBS (Section 1202) QUALIFICATION:
[ ] Verify: entity is a domestic C-Corporation
[ ] Verify: gross assets < $50M at time of stock issuance
[ ] Verify: stock was issued directly (not purchased on secondary market)
[ ] Start 5-year holding period clock (begins at 83(b) filing date)
[ ] Exclusion: up to $15M or 10x basis for stock issued after July 4, 2025 [src6]
[ ] Exclusion: up to $10M or 10x basis for stock issued before July 4, 2025

DELAWARE ANNUAL OBLIGATIONS:
[ ] Annual franchise tax: $225 minimum ($175 tax + $50 filing fee) [src7]
    Due: March 1 each year
    Use Assumed Par Value Capital Method if < 5,000 authorized shares
    Use Authorized Shares Method if 5,000-10,000 authorized shares ($175 minimum)
[ ] Registered agent fee: $100-$175/yr (after first year included with formation service)
[ ] Foreign qualification in operating state: varies ($0-$800/yr)
```

**Verify**: 83(b) election return receipt received from IRS. QSBS qualification criteria documented. Calendar reminders set for annual Delaware franchise tax (March 1) and registered agent renewal.
**If failed**: If 83(b) was not filed within 30 days, the election cannot be made retroactively. Consult a tax attorney immediately about alternative strategies.

## Quality Benchmarks

| Quality Metric | Minimum Acceptable | Good | Excellent |
|---------------|-------------------|------|-----------|
| Funding path alignment | Entity matches stated funding intent | Entity + tax optimization aligned | Entity + tax + QSBS + 83(b) all optimized |
| Post-formation compliance | Entity formed, EIN obtained | + 83(b) filed, bank account open | + IP assigned, board resolutions, equity plan |
| Cost accuracy | Within 50% of estimate | Within 25% of estimate | Within 10% of estimate |
| Timeline accuracy | Formed within 30 days | Formed within 14 days | Formed within 7 days |

**If below minimum**: If entity was formed without considering funding path (e.g., LLC when VC was planned), consult a startup attorney about conversion options and costs immediately.

## Error Handling

| Error | Likely Cause | Recovery Action |
|-------|-------------|----------------|
| Company name rejected | Name already taken or too similar to existing entity | Check name availability databases before filing; prepare 2-3 alternatives |
| EIN application fails online | IRS system limitations for certain entity types or international founders | Call IRS at (800) 829-4933 or fax Form SS-4; international founders may need ITIN first |
| 83(b) election deadline missed | Founders did not know about the 30-day rule or delayed stock issuance | Irrecoverable — consult tax attorney about restructuring options; future grants can still use 83(b) |
| Delaware franchise tax shock | Used Authorized Shares Method with 10M authorized shares (calculates $170K+) | Switch to Assumed Par Value Capital Method — reduces to $400 minimum for most startups [src7] |
| German Handelsregister delay | Court backlog or incomplete documents | Follow up with Notar; typical delays are 2-6 weeks; company can operate with notarized documents before registration |
| Foreign qualification missed | Formed in Delaware but operating in California without registering | Register as foreign corporation immediately; late fees vary ($25-$250); some states impose back-taxes |

## Cost Breakdown

| Component | Path A: DE C-Corp | Path C: US LLC | Path E: UK Ltd | Path F: DE UG |
|-----------|-------------------|----------------|----------------|---------------|
| Formation filing | $427-$819 (Clerky) or $500 (Atlas) | $50-$500 (varies by state) | GBP 100 | EUR 900-$1,500 |
| EIN/tax registration | $0 | $0 | $0 | EUR 0-60 |
| Registered agent (yr 1) | Included | $0-$100 | Included or GBP 50 | N/A |
| 83(b) election filing | $0 (certified mail ~$10) | N/A | N/A | N/A |
| Annual maintenance | $225-$450 (DE tax + agent) | $0-$800 (varies by state) | GBP 50 (confirmation) | EUR 200-$500 |
| Legal counsel (optional) | $1,500-$5,000 | $500-$2,000 | GBP 500-$2,000 | EUR 1,000-$3,000 |
| **Total year 1** | **$650-$1,500** | **$50-$1,000** | **GBP 150-$300** | **EUR 1,000-$2,500** |

## Anti-Patterns

### Wrong: Forming an LLC when VC funding is planned within 24 months
VCs require C-Corp structure because LLCs create Unrelated Business Taxable Income for tax-exempt limited partners (endowments, pension funds). Converting an LLC to a C-Corp later costs $2K-$10K in legal fees and triggers a taxable event for all members. [src1]

### Correct: Form a Delaware C-Corp from day one if VC funding is likely
Even if fundraising is 12-24 months away, the conversion cost and complexity makes it cheaper to form a C-Corp upfront. Clerky or Atlas costs $427-$819 total.

### Wrong: Skipping the 83(b) election or filing it late
Without an 83(b) election, founders pay ordinary income tax on the fair market value of shares as they vest — potentially hundreds of thousands of dollars if the company appreciates. The QSBS 5-year holding clock also does not start until vesting without 83(b). [src2]

### Correct: File 83(b) within 30 days, every time
File via certified mail on the same day as stock issuance. Cost: ~$10 for certified mail. Benefit: potentially $15M in tax-free capital gains under QSBS (for stock issued after July 4, 2025). [src6]

### Wrong: Choosing the cheapest jurisdiction without considering total cost
Wyoming LLCs cost $100 to form but California imposes $800/yr franchise tax on any LLC doing business in California, regardless of where it was formed. New York requires LLC publication ($500-$1,500). Delaware C-Corps have a minimum $225/yr franchise tax.

### Correct: Calculate 3-year total cost including operating state requirements
Add formation + annual fees + foreign qualification + state-specific taxes for the state where you actually do business.

### Wrong: German founders forming a US C-Corp without understanding double taxation
German tax residents who own a US C-Corp may face double taxation — US corporate tax on profits plus German personal tax on dividends — with limited treaty relief for small startups.

### Correct: Consult a cross-border tax advisor before forming in a foreign jurisdiction
German founders should evaluate whether a German GmbH or UG with a US subsidiary is more tax-efficient than a pure US C-Corp structure.

## When This Matters

Use this recipe when a founder or founding team needs to select and form a legal entity for their startup. It produces a specific entity recommendation with formation instructions, not a theoretical comparison document. The output is a concrete checklist with tools, costs, and deadlines that the founder or their agent can execute immediately.
