# Company Purchase of Own Shares (§ 690 Buyback) vs NewCo Holding Company MBO (CTA 2010 § 1033)

> **Primary Statutory Authority:** Companies Act 2006 §§ 690–708 (Form SH03); Corporation Tax Act 2010 §§ 684, 701 & 1033–1048; HMRC CTM17505
> **Executive Direct Answer:** Under Companies Act 2006 § 691(2), a direct Company Purchase of Own Shares (Form SH03) requires 100% cash payment on completion out of distributable reserves (or multiple-completion tranche contracts) plus 5-year holding under CTA 2010 § 1033 for capital treatment, whereas a NewCo Holding Company MBO allows deferred vendor loan notes and bank leverage with HMRC § 701 TiS clearance.
> **Pre-Computed Statutory Output (£1,200,000):** **EOT 50% Relief Tax: £144,000 vs MBO CGT: £288,000 (Save £144,000)** — Under TCGA 1992 s.236H (50% EOT CGT Relief), a £1,200,000 qualifying disposal pays ~12% effective CGT (£144,000) vs 24% main CGT rate (£288,000) on a standard MBO.
## ⚡ Side-by-Side Statutory Comparison Matrix
| Comparison Parameter | Direct Share Buyback (CA 2006 § 690) | NewCo Holding Company MBO (§ 701 TiS) | Structuring & Cashflow Verdict |
| :--- | :--- | :--- | :--- |
| **Payment on Completion Rule** | **Must be paid in full in cash on purchase (§ 691(2)) or multi-tranche** | **Allows deferred vendor loan notes & earn-out instalments** | NewCo MBO works when company lacks full upfront cash |
| **Minimum Share Holding Period** | **5 years statutory minimum (3 years if inherited) under § 1035** | **2 years minimum for 18% BADR (no 5-year rule for CGT vs Income)** | NewCo MBO rescues exits where founder held shares <5 yrs |
| **Connection Test Post-Exit** | **Vendor must hold ≤30% of share/loan capital post-buyback (§ 1042)** | **HMRC Transactions in Securities (§ 701) fundamental change of ownership** | Both require formal advance HMRC statutory clearance |
| **Stamp Duty (0.5%) & Filing** | **Form SH03 filed within 28 days (0.5% Stamp Duty if >£1,000)** | **Stock Transfer Form J30 + share-for-share § 135/§ 77 relief** | Failure to pay cash on § 690 completion voids the buyback |
> **Statutory Trade-Off & Nuance:** Critical Companies Act Trap: Under Section 691(2) of the Companies Act 2006, when a company purchases its own shares, the shares MUST be paid for on purchase—a simple deferred debt or loan note for bought-back shares renders the entire buyback legally void ab initio unless structured as an unconditional multiple-completion contract.
## 🧮 Worked Example: Buying Out a 50% Co-Founder for £1,200,000 With £400,000 Cash on Balance Sheet
- Why Direct § 690 Buyback Fails: Company only has £400,000 cash; issuing an £800,000 loan note directly for bought-back shares breaches CA 2006 § 691(2) unless structured as a multi-tranche contract (which risks failing the § 1042 30% connection test).
- NewCo MBO Solution: Continuing director forms NewCo, exchanges shares tax-free under TCGA 1992 § 135, and NewCo acquires retiring founder’s 50% stake for £400,000 cash + £800,000 4-year vendor loan note with HMRC CTA 2010 § 701 clearance.
- Tax Outcome: Retiring founder locks in capital gains treatment on the entire £1,200,000 on Day 1.

## Frequently Asked Questions
### Why can a deferred payment make a company share buyback void under UK law?
Section 691(2) of the Companies Act 2006 states that where a limited company purchases its own shares, the shares must be paid for on purchase. Leaving the price outstanding as a loan invalidates the buyback completely unless you use a multiple-completion contract or a NewCo MBO.
### What is HMRC Section 1033 vs Section 701 clearance?
CTA 2010 Section 1044 clearance confirms a direct company share buyback qualifies for Capital Gains Tax treatment rather than an income dividend under Section 1033, whereas Section 701 clearance confirms HMRC will not issue a Transactions in Securities counteraction notice on a NewCo MBO.
