Alphabet shares are the standard property-SPV mechanic for using a spouse's basic-rate band or an adult child's unused dividend allowance in the current tax year. The design is simple: A / B / C ordinary classes, each with its own dividend right, declared independently. The controlling shareholder retains decision-making while the spouse, adult child, or other family member holds a non-controlling class and receives dividend cash directly to their own bank account.

What makes the design legally robust (or fragile) is not the share-class mechanic but the settlements legislation in ITTOIA 2005 s.624 to s.628 and the way the courts and HMRC have interpreted the s.626 spouse exception since Jones v Garnett (Arctic Systems) [2007] UKHL 35. This page works through the rule, the spouse exception, the adult-child case, the minor-child trap, the articles-drafting points that determine whether the structure survives an HMRC enquiry, and three worked allocation examples for a property SPV. It is the income-now mechanic; the growth-share or freezer-share design used for inheritance tax value-freeze planning is covered in our wider Family Investment Company material.

What alphabet shares are, in a property SPV context

A standard property SPV starts life with a single class of ordinary shares, typically 100 ordinaries held by the founder. The alphabet design re-issues the share register with multiple classes:

  • A ordinary shares for the founder, carrying voting rights, dividend rights, and capital rights.
  • B ordinary shares for the founder's spouse, identical to A except that dividends declared on the B class are independent of dividends declared on the A class.
  • C ordinary shares for an adult child, identical to A and B except for independent dividend declaration.
  • D, E, F classes as needed for additional family members.

Each class is a genuine ordinary share: it carries one vote per share at general meetings, ranks equally on capital distribution, and has a dividend right that is "such dividend as the directors may from time to time declare on this class". The classes are identical in every legal respect except that the directors can declare dividends on one class independently of the others. Voting and capital rights are unchanged.

That distinction matters legally. A share class that is restricted to dividend rights only (no voting, no capital) starts to look like a right to income rather than a genuine ownership stake, and HMRC argues such a class converts the gift into a settlement of income rather than a transfer of property. The s.626 spouse exception protects ordinary share gifts; it does not protect income-only carve-outs. Get the articles right and the s.626 path is open; get them wrong and the design fails on the legal-form test before any of the bounty arguments even start.

For comparison with other share-class designs, alphabet shares are not the same thing as growth shares or freezer shares. Growth shares are designed to capture future capital appreciation in a different class to the founder's; freezer shares lock the founder's capital value at a point in time. Those are IHT-planning mechanics. The alphabet design is purely an income-tax tactic for the current tax year. The two designs can coexist (founder preference class plus alphabet classes among the family plus growth shares for the children); that combined structure is FIC-grade and covered in our wider Family Investment Company material.

The s.624 settlements legislation, the rule everyone needs to understand first

ITTOIA 2005 s.624 is the anti-avoidance rule that treats income arising under a "settlement" as the income of the settlor, where the settlor retains an interest in the property comprised in the settlement. A settlement, for these purposes, is defined widely in s.620: it includes any "arrangement", and an arrangement that confers a benefit on the settlor's family with an element of bounty is the central case.

The two-step test the courts apply (developed through Crossland v Hawkins, IRC v Plummer, and confirmed in Jones v Garnett):

  1. Is there a "settlement"? The arrangement must have an element of bounty, meaning the donor has done something gratuitously that benefits the donee. A pure commercial transaction (full consideration paid, market-rate exchange) is not a settlement; a gift, an undervalue transfer, or an arrangement that effectively diverts the donor's income to the donee, is.
  2. Is the settlor "interested" in the settled property? The s.625 definition catches the settlor where the property or any income from it can be paid to or applied for the benefit of the settlor or the settlor's spouse.

If both legs are satisfied, dividends paid to the donee on the settled shares are attributed back to the settlor for income-tax purposes, regardless of whose hand actually receives the cash.

HMRC's published guidance on shares-as-settlement sits in the Trusts, Settlements and Estates Manual at TSEM4205 onwards, with the spouse-exception guidance at TSEM4305 onwards. The manual is the operational reference HMRC officers use at enquiry, and the test it sets out is the same two-step test described above.

Arctic Systems and the s.626 spouse exception

Jones v Garnett [2007] UKHL 35 is the central case. Mr Jones was a computer consultant who set up Arctic Systems Limited in 1992. He and Mrs Jones each subscribed for one £1 ordinary share. Mr Jones ran the consultancy work (the company's only real revenue source); Mrs Jones provided administrative support. Both received modest salaries and equal dividends, including £25,767 each in the disputed 1999/2000 tax year.

HMRC argued the arrangement was a settlement of income from Mr Jones to Mrs Jones (because Mrs Jones's economic contribution was much smaller than her share of the dividends, and Mr Jones effectively controlled when dividends were declared and to whom). HMRC further argued that the s.626 spouse exception did not apply because Mrs Jones's share was effectively a right to income only.

The House of Lords held, by a 3-2 majority:

  • Yes, the arrangement was a settlement within s.624. There was an element of bounty: Mr Jones gratuitously transferred income-earning capacity to Mrs Jones through the share structure.
  • BUT s.626 (the spouse exception) applied. Mrs Jones's share was an outright gift of an ordinary share. The s.626 condition is that the gift must not be "wholly or substantially a right to income". An ordinary share (voting, dividend, capital) is not wholly or substantially a right to income, even where the practical economic value sits in the dividend.
  • Conclusion: the dividends paid to Mrs Jones were not attributed back to Mr Jones. The settlements legislation did not bite.

The Arctic Systems outcome confirmed two propositions:

  1. An outright gift of genuine ordinary shares to a spouse is protected by s.626 even where the substantive economic value is the dividend stream.
  2. A share class restricted to income only (no voting, no capital) would NOT be protected, because such a class is "wholly or substantially a right to income".

That second proposition is the design constraint on the alphabet structure. Each class must be a genuine ordinary share for the spouse exception to work.

Designing the alphabet structure for an SPV with a spouse

The common pattern for a property SPV with a married founder and spouse:

  • 100 A ordinaries to the founder, £1 each.
  • 100 B ordinaries to the spouse, £1 each, transferred from the founder by outright gift.
  • Both classes carry one vote per share, equal capital rights, and an independent dividend right.

The legal steps:

  1. Special resolution to amend articles introducing the B class with identical voting and capital rights to A class but independent dividend declaration.
  2. Director allotment of the 100 B shares to the founder (SH01 to Companies House).
  3. Stock-transfer form from founder to spouse, completed without consideration. CGT on the transfer is no-gain-no-loss under TCGA 1992 s.58 (spouse transfer exemption). Stamp duty on the transfer is zero (under £1,000 consideration or simple gift).
  4. Updated members' register entry for the spouse holding B shares. Updated PSC register.
  5. Board minute recording the allotment and transfer with explicit confirmation that the transfer is an outright gift with no retained interest.

Worked allocation example: married founder and spouse

An anonymised property SPV: Mark and Sarah, three buy-to-let properties in Manchester held in MS Property Ltd. Year-end 2026/27 distributable reserves £75,000. Mark is a higher-rate taxpayer with £80,000 of other income (consultancy work outside the SPV). Sarah is a part-time NHS nurse with £25,000 of salary income.

Single-class structure (founder owns 100% of one ordinary class): Mark draws all £75,000 as dividends. The £500 dividend allowance covers the first slice, the next £42,270 fills his basic-rate band (which is exhausted by his other income, so this is taxed at 35.75%), and £32,230 falls into higher-rate dividend territory at 35.75%. Total dividend tax on Mark: roughly £26,650.

Alphabet structure (50:50 split between Mark on A class and Sarah on B class): Mark draws £20,000 as A-class dividend. Sarah's basic-rate band (£50,270 less her £25,000 salary = £25,270 of remaining band) accommodates her £25,000 B-class dividend at 10.75%. Mark's £20,000 A-class dividend, on top of his £80,000 of other income, sits entirely in higher-rate at 35.75%.

  • Mark's tax: £20,000 × 35.75% = £7,150 (he loses the £500 allowance to his other dividend income).
  • Sarah's tax: (£25,000 - £500 allowance) × 10.75% = £2,634.
  • Total household dividend tax: £9,784.

The alphabet structure saves £26,650 - £9,784 = £16,866 of dividend tax in this single tax year compared to the single-class baseline. The saving compounds year on year while the income-band positions hold.

Adult children: where the spouse exception does NOT apply

The s.626 spouse exception is spouse-only (legally married or in a civil partnership). For an adult child (over 18), the only test is whether the share gift falls within s.624 in the first place. The two questions:

  1. Is the share a genuine ordinary share (not stripped to income-only)? If yes, the design is on the right side of the Arctic Systems "wholly or substantially a right to income" line.
  2. Is the gift outright, with no element of bounty arrangement that returns the dividend income to the parent's benefit? Adult children are free to use dividend cash for their own living costs; the challenge HMRC runs is where dividend cash demonstrably funds expenses the parent would otherwise pay personally.

Worked allocation example: founder, spouse, and adult child

Same SPV as before. The adult child, Tom (22, recent graduate, £14,000 of part-time income), holds a C class. Mark wants to support Tom's first-year work-life by allocating part of the dividend to him.

Allocation: Mark £20,000 (A), Sarah £25,000 (B), Tom £30,000 (C). Total £75,000.

  • Mark's tax: £20,000 × 35.75% = £7,150.
  • Sarah's tax: (£25,000 - £500 allowance) × 10.75% = £2,634.
  • Tom's tax: Tom has £14,000 of salary, so the first £-12,570 of his salary uses personal allowance, the next £1,430 is taxed at basic 20%. His £500 dividend allowance covers the first slice of his £30,000 dividend. The next £29,500 is taxed at 10.75% (he has £33,840 of basic-rate band remaining after salary). Tom's tax: £29,500 × 10.75% = £3,171.
  • Total household dividend tax: £7,150 + £2,634 + £3,171 = £12,955.

Compared to the all-Mark single-class baseline of £26,650, the three-way alphabet saves £13,695. Note Tom's dividend cash must actually reach him and stay there; if Tom's £30,000 is paid into Mark and Sarah's joint account and used for household expenses, the arrangement collapses on the s.624 element-of-bounty test.

Minor children and the s.629 trap

ITTOIA 2005 s.629 treats income paid to or for the benefit of an unmarried minor child of the settlor as the settlor's income. There is no spouse-exception equivalent. The £100-per-parent de minimis is too small to matter for any real alphabet design.

Practical consequences:

  • Direct gift of shares to a minor child is unworkable for income-tax purposes. Dividends declared on the child's class are attributed back to the parent.
  • Bare-trust holding of shares for a minor child (the standard route for gifting investments to under-18s) does not solve the income-tax problem: s.629 looks through the bare trust to the underlying beneficial owner.
  • The IHT planning view is different. A gift into a discretionary trust for a minor child can be a chargeable lifetime transfer (CLT) with a 20% entry charge on excess over the nil-rate band, but the s.629 attribution still applies to any income arising on those shares during the child's minority. The trust structure does not avoid the income-tax attribution; it only changes the IHT side of the picture.
  • The practical workaround is to wait. A child aged 16 receives a gift of shares; for the two years until age 18 the income attributes to the parent; from the 18th birthday onwards the s.629 attribution stops and the alphabet structure works on the standard adult-child basis.

How to design the share classes: articles-drafting points

The articles of association are the legal document that defines the class rights. Get the articles right and the s.624 test is on safe ground; get them wrong and HMRC has a structural challenge before any factual enquiry begins.

Five drafting points:

  1. Each class must be a genuine ordinary share. Carry one vote per share, equal capital rights on liquidation, equal ranking. The only differential is independent dividend declaration. Do not restrict the class to "right to dividends only".
  2. Dividend right phrased as "such dividend as the directors may from time to time declare". Avoid fixing a rate, a frequency, or a guaranteed level. A fixed coupon converts the class to a preference share, which is a different structure with different tax consequences.
  3. Class-rights variation requires class consent. CA 2006 s.630 provides that variation of class rights needs the consent of holders of three-quarters of that class. Build this into the articles explicitly.
  4. Pre-emption rights on transfer are optional. Many family SPVs add a pre-emption right requiring offer to other shareholders before external sale; this is fine for income-tax purposes as long as it does not give the original donor an effective veto or buy-back right.
  5. Articles amendment requires a special resolution. CA 2006 s.21 sets the 75% threshold. Where the founder holds 100% of the existing class at the time of amendment, the special resolution is procedural; where the spouse already holds some shares, both holders must agree.

Dividend declaration discipline

The class-by-class declaration is the mechanic that makes the alphabet structure work in practice. HMRC reads board minutes at any enquiry to confirm the structure was operated as designed.

Required for each declaration:

  • Board resolution dated and signed, naming the class, the rate per share or total amount, and the payment date.
  • Distributable-reserves confirmation: the company must have sufficient distributable profits under CA 2006 s.830, evidenced by reference to the latest filed or interim management accounts.
  • Dividend voucher issued to each shareholder for each declaration, showing the gross dividend and tax credit where relevant.
  • Bank movement on the same date as the declaration or shortly thereafter.
  • Self Assessment entry for each shareholder declaring the gross dividend.

HMRC guidance on declaration mechanics is in the Company Taxation Manual at CTM15205 onwards. The two failures we see most often at enquiry are (a) board minutes that record a "general dividend declaration" without specifying the class, and (b) bank movements that pre-date or post-date the minuted declaration by months. Both invite the argument that the declaration was retrofitted to support the desired allocation, not contemporaneous.

Where it all goes wrong: HMRC challenge patterns

Five fact patterns HMRC pursues at enquiry, in order of frequency:

  1. Stripped share class. The donee's class has dividend rights only, no voting and no capital. The Arctic Systems test fails because the class is "wholly or substantially a right to income". HMRC argues the s.626 exception does not apply (for spouses) or the s.624 test bites unprotected (for adult children).
  2. Dividend cash returned to donor's benefit. The B-class dividend lands in a joint account and is used for household expenses the donor would otherwise pay personally. The s.624 element-of-bounty argument is reinforced.
  3. Retrospective allocation. Dividends declared "on the spouse's class" by board minute back-dated to support a Self Assessment filing. HMRC obtains bank records and resolves the declaration date against actual cash movement; mismatched dates collapse the structure.
  4. Bare-trust shares for minor children. The s.629 attribution is unambiguous. The trust structure does not solve the income-tax issue. Where parents have been declaring substantial dividends on minor-child classes, HMRC reassesses to attribute the income to the parent and applies penalties for the historic returns.
  5. Income-only "growth" carve-out. A class is described as a "growth share" with only a contingent dividend right tied to performance, gifted to an adult child. The contingent design is hybrid between alphabet and growth-share structures. HMRC argues the class is wholly or substantially a right to income (in the contingent form) and the gift is caught.

Combining alphabet shares with the wider extraction sequence

The alphabet structure is one input into the wider extraction sequence covered on our BTL director's loan repayment strategy page. Where the founder also has a credit director's loan account from a section 162 incorporation, the DLA repayment runs through the founder's hands tax-free regardless of the alphabet structure (DLA principal repayment is a balance-sheet movement, not a dividend declaration). The alphabet design optimises the dividend layer that sits on top of the DLA strand; it does not change the DLA mechanic.

The same applies to corporation tax. The company pays CT on its profits before any dividend is available for declaration; alphabet shares change how the post-CT cash is sliced across shareholders, not the underlying tax rate the company pays. Our property company dividend tax page covers the rate-and-band detail; our salary versus dividends profit extraction page covers the wider extraction trade-offs.
