Alphabet shares are separate classes of shares in a limited company is labelled A, B, C and so on, that let the board pay different dividend amounts to different shareholders, independent of how much of the company each person owns. UK property investors use them inside an SPV to control who receives income, and when, without changing underlying ownership percentages.
Alphabet shares in a limited company are different classes of shares (labelled A, B, C, and so on) in the same company, where each class carries its own rights to dividends, voting, and capital. Because dividends can be declared separately on each class, the company can pay one shareholder a different amount from another in the same year. This is what makes alphabet shares in a limited company so useful in family-owned property SPVs.
If you and a spouse, civil partner or family member own a property SPV together and want flexibility over how rental profits are paid out, this guide is for you. It covers what alphabet shares are, how they differ from ordinary shares, why companies use them, what HMRC’s settlements rules say, and the exact process to set them up.
Key Takeaways
- Alphabet shares let a property company pay different dividend levels to different shareholder classes, independent of how much of the company each person actually owns
- Property SPVs are typically built around one of three ownership models: single-class ordinary shares, alphabet shares, or mixed-rights structures used in family investment companies
- For 2026/27, the dividend allowance stays at £500, but dividend tax rates rose to 10.75% (basic), 35.75% (higher), and 39.35% (additional), which directly affects how much an alphabet share split can actually save
- Changing a shareholding structure, whether by allotment, transfer, buyback, or creating a new class, requires specific Companies House filings (such as SH01 or SH03) and often a 75% shareholder special resolution
- Since November 2025, anyone who becomes a new person with significant control (PSC) through a share allotment must complete identity verification with Companies House before related filings will be accepted
- HMRC’s settlements legislation can challenge alphabet share arrangements between spouses or civil partners if shares are dividend-only rather than carrying full voting and capital
What Are Alphabet Shares In a Limited Company?
In a limited company, alphabet shares are simply the named share classes created by setting out distinct rights for each in the articles. A typical small property SPV might issue A shares to one director, B shares to their spouse or civil partner, and reserve C shares to bring a family member in later.
Each class can be given the same voting and capital rights as the others, or different ones, depending on the owners’ aims. The Corporation Tax position of the company itself is unaffected by how the shares are split.
Crucially, the articles of association must expressly permit multiple classes and define their rights. Most off-the-shelf “model articles” used at incorporation assume a single class, so before alphabet shares in a limited company can work, they almost always need amending by special resolution.
How Do Alphabet Shares Differ From Ordinary Shares?
A standard company has a single class of ordinary shares. Every shareholder holds the same type of share, and any dividend declared must be paid to all of them in proportion to their holding. You cannot legally pay one ordinary shareholder more per share than another of the same class.
Alphabet shares break a company’s equity into two or more classes, each labelled with a letter. The letters carry no legal meaning in themselves; they are simply labels. What matters is the rights attached to each class, which are defined in the articles of association.
The defining difference is selective dividends. With one class, a £10,000 dividend must be shared by everyone pro rata. With A and B classes, the directors can declare £10,000 on the A shares and nothing on the B shares in the same financial year. Alphabet shares are still a type of ordinary share; the distinction is the existence of multiple classes with their own rights, not a separate category of security.
Why Do UK Companies Use Alphabet Shares?
The most common driver is flexible dividend planning. Because each class can receive a different dividend, a couple where one person is a higher-rate taxpayer and the other has unused basic-rate band or personal allowance can direct income more efficiently, provided the lower-earning shareholder genuinely owns full-rights shares and the dividends are lawful.
A second reason is bringing in family or investors without giving away control. You can issue a class that carries dividend rights but no votes, or votes but limited capital. This separates economic benefit from control, which is valuable for succession.
used at incorporation assume a single class, so before alphabet shares in a limited company can work, they almost always need amending by special resolution.. Once the classes exist, varying dividends between them each year is far easier than repeatedly transferring shares. For property SPVs with a long hold
How Does HMRC Treat Alphabet Shares?
Alphabet shares are entirely legal, but HMRC scrutinises them where they are used to shift income within a family. The key provisions and principles below are what determine whether a structure holds up.
The Settlements Legislation: ITTOIA 2005, Part 5, Chapter 5
Where one person arranges for their income to be diverted to another, typically a lower-earning spouse or child, HMRC can tax that income as though it still belonged to the person who created the arrangement. The core charge sits in section 624, where the settlor retains an interest in the settled property. This is the central risk for family alphabet share structures.
The Spousal Exemption: Jones v Garnett (Arctic Systems) [2007] UKHL 35
Section 626 provides an exemption for genuine outright gifts between spouses or civil partners, unless the gift is “wholly or substantially a right to income”. In Arctic Systems, a gift of ordinary shares carrying full rights fell within this exemption. The practical rule is that shares given to a spouse must be normal full-rights shares, not a stripped-down dividend-only class.
Minor Children: ITTOIA 2005, Section 629
The spousal exemption does not extend to minor children. Income from shares a parent gifts to their unmarried minor child is treated as the parent’s income where it exceeds £100 in the tax year, and that £100 limit applies per parent, per child, as explained in the HMRC manual TSEM4300.
Dividends Must Be Lawful: Companies Act 2006, Part 23
A dividend can only be paid from accumulated, realised profits, must be properly declared, and must be documented with board minutes and a dividend voucher for each class. A dividend paid without sufficient distributable profits is unlawful and can be reclaimed.
The overarching message is that the structure must reflect real ownership and real rights, with contemporaneous paperwork. Artificial arrangements with no genuine substance are where enquiries begin.
Alphabet Shares In Property SPVs
A property SPV is a limited company set up to hold Buy-to-Let or other investment property. Alphabet shares in a limited company suit these companies because most are owned by one or two people (often a married couple) rather than a wide investor base, which makes dividend flexibility directly relevant to how rental profits are drawn.
Property SPVs also tend to have long horizons and clear succession aims. Separate classes make staged gifting to children manageable over years rather than in one event. A husband-and-wife SPV might run A and B classes now, with C shares reserved to issue to children once they are adults.
There are property-specific factors to weigh too. Many SPV Buy-to-Let lenders impose conditions on company ownership and shareholders, so a share reorganisation can breach loan terms if not cleared first. The wider position on Stamp Duty Land Tax (SDLT), Capital Gains Tax (CGT) and Inheritance Tax (IHT) on the eventual exit should also be considered before, not after, the classes are created.
Worked Example: How Alphabet Shares Change the Tax Bill
Angela and Daniel set up a property SPV three years ago to hold two Buy-to-Let flats. On their accountant’s standard incorporation, the company was issued one class of ordinary shares, split 50/50. Daniel works full-time as an IT contractor and already earns about £75,000, putting him firmly in the higher-rate band. Angela left her job after their second child and has no other income this year.
This year, the SPV has £30,000 of profit left after Corporation Tax, which they want to distribute as dividends to cover the family’s costs. Because they hold a single class of shares, any dividend has to follow the 50/50 split, i.e., £15,000 each, whether that suits their tax positions or not.
Here is what that forced split costs them in the 2026/27 tax year, against what they could have done with two share classes. The Dividend Tax rates used are the 2026/27 rates of 10.75% (basic) and 35.75% (higher), and each shareholdeer’s £500 dividend allowance and, for Angela, her £12,570 personal allowance are applied:
By moving the income onto Angela’s class, where she has a whole personal allowance and basic-rate band going spare, the same £30,000 reaches the family for roughly £3,250 less tax in a single year.
But here’s the catch for Angela and Daniel. This only works if Angela genuinely owns proper B shares carrying full voting and capital rights, not a “dividend-only” class, following the principle in Jones v Garnett (Arctic Systems). If HMRC views her shares as substantially just a right to income, the settlements legislation can tax that £28,000 back on Daniel and wipe out the saving. Each dividend also needs its own board minute and voucher at the time it is declared.
How to Set Up Alphabet Shares In a Property SPV?
Alphabet shares in a limited company can be created at incorporation or by reorganising an existing company. The process below applies to an existing SPV.
Done properly, this is a routine reorganisation. The value lies in getting the rights and the advice right at the outset, not in the filings themselves.
Common Mistakes & Risks With Alphabet Shares
Most problems come from poor execution rather than the concept. The recurring failures are:
Dividend-Only Shares to a Spouse
Shares carrying only dividend rights risk falling outside the spousal exemption and being caught by the settlements legislation. Use full-rights shares.
Dividends Without Distributable Profits
A dividend paid where there are no accumulated realised profits is unlawful under Companies Act 2006, Part 23.
Missing or Backdated Paperwork
No board minute, no voucher, or documents created after the event undermines the whole arrangement.
Gifting Shares to Minor Children
Income on shares a parent gives a minor child is generally taxed back on the parent.
Articles That Do Not Permit Classes
Paying differential dividends without amending the articles leaves them open to challenge.
Ignoring Lender Conditions
SPV mortgage lenders often restrict ownership changes; reorganising without checking can breach the loan.
Artificial Structures With No Substance
Arrangements that exist only to move income, with no real gift or ownership, attract enquiry.
Forgetting the Wider Tax Picture
CGT, SDLT and IHT all interact with how shares are held and how the SPV is eventually sold.
Conclusion
If you own a property SPV with a spouse or family member and want control over how rental profit is paid out, alphabet shares are likely worth considering, but only if they are set up with full-rights classes, correct articles, and documented dividends. This is not a structure to copy from a template.
The settlements legislation and your mortgage terms can both undo a poorly built arrangement. Get the design right once, and alphabet shares in a limited company give a property SPV years of dividend and succession flexibility. If you want your SPV’s share structure reviewed or set up correctly, here’s how to take the next step.

FAQs
Alphabet shares are different classes of shares in the same UK limited company, each labelled with a letter such as A, B or C. Each class can carry its own rights to dividends, voting and capital. This lets the company treat each class differently.
Their main purpose is flexibility. Because dividends can be declared separately on each class, a company can vary distributions between shareholders year to year. They are also used to bring family members or investors into a company without giving away control, and to support succession and estate planning over time.
With a single class of ordinary shares, every holder has identical rights and dividends are paid pro rata. You cannot pay different amounts to different holders. With alphabet shares (multiple classes), dividends can be declared separately on each class, and voting and capital rights can differ by class. Alphabet shares are still a form of ordinary share; the difference is having multiple classes with their own rights.
Yes. Alphabet shares are fully legal and widely used. The risk is not the structure itself but misuse. For example, diverting income to a spouse via dividend-only shares, which can be caught by the settlements legislation (ITTOIA 2005, Part 5, Chapter 5). Genuine full-rights gifts, lawful dividends and proper paperwork keep the structure sound.
Yes, and they are common in family-owned SPVs because they allow rental profits, after Corporation Tax, to be distributed flexibly between owners.
