Form 5471 Schedule A, titled Stock of the Foreign Corporation, is the short two-column schedule on which a US owner of a UK company lists each class of stock the company has issued and states how many shares of that class were outstanding at the beginning and at the end of the annual accounting period of the company. For a high-net-worth American with an interest in a UK company, Schedule A is one of the smallest schedules on Form 5471 by column count and one of the easiest to get wrong, because the US concept of a class of stock has no single fixed UK equivalent. UK company law recognises ordinary shares, preference shares, alphabet shares, growth shares, redeemable shares and deferred shares, each carved out of the same share capital records that Companies House holds on public file, and each of those class descriptions has to be translated onto Schedule A in a way that also matches, word for word, the class description used later on Schedule B. This article works through what Schedule A actually asks for, how a UK statement of capital and a Companies House form SH01 filing map onto it, and where preparers most often create an inconsistency between Schedule A and Schedule B.
What is Form 5471 Schedule A?
Schedule A is one of the schedules attached to Form 5471, Information Return of U.S. Persons With Respect to Certain Foreign Corporations, the form the IRS uses to collect ownership and financial information about foreign corporations that are controlled or substantially owned by US persons. On the printed form, Schedule A sits near the front of the return and asks for only two pieces of information for each class of stock the foreign corporation has issued: a description of the class in column (a), and the number of shares issued and outstanding in column (b), reported separately for the beginning and the end of the annual accounting period of the company. Value, currency and nominal amount are not asked for on Schedule A itself; those details are reported elsewhere in the return.
Who must complete Schedule A?
Not every category of Form 5471 filer completes Schedule A. The filing requirements chart in the current Instructions for Form 5471 lists Schedule A as required of Category 2, Category 3 and Category 4 filers. In practice that captures the two groups of Americans who own UK companies most often: a US citizen or resident who is an officer or director of the company at the point a US person crosses the relevant ownership threshold, and a US person who controls the company outright. Category 1 and Category 5 filers, who are US shareholders of the company without meeting the officer, director or control tests, are not required to complete Schedule A, though they still complete Schedule B.
The structure of Schedule A: columns (a) and (b)
Schedule A gives one row to each class of stock the foreign corporation has issued and asks the preparer to complete two columns for that row, using figures drawn from the share register of the company rather than any US concept of stock.
- Column (a), description of each class of stock: a short, consistent label for the class, for example ordinary shares or A ordinary shares, entered exactly as it will also appear in column (b) of Schedule B.
- Column (b)(i), number of shares issued and outstanding, beginning of annual accounting period: the share count for that class on the first day of the accounting period being reported.
- Column (b)(ii), number of shares issued and outstanding, end of annual accounting period: the share count for the same class on the last day of that period, after any allotments, transfers, redemptions or cancellations during the year.
How UK share classes map onto Schedule A column (a)
The share capital of a UK company rarely consists of a single class of ordinary shares once it has taken on outside investors, rewarded founders separately from investors, or built in flexibility for a future exit. Each class Companies House has on record for the company, drawn from its statement of capital and its history of allotment filings, should reappear on Schedule A as its own row, using the same class name the company itself uses in its articles of association and its statutory register of members. Common UK share classes, and how they typically appear on Schedule A, include the following.
- Ordinary shares: the standard class, usually carrying one vote per share, a right to dividends and a right to capital on a winding up, generally entered on Schedule A simply as ordinary shares.
- Preference shares: shares carrying a fixed or preferential dividend and often a priority return of capital ahead of the ordinary class, entered as preference shares or preferred ordinary shares to match whatever term the documents of the company use.
- Alphabet shares, such as A ordinary, B ordinary and C ordinary: separate classes typically created so each founder or each investor group can receive a different dividend, entered on Schedule A as distinct rows, for example A ordinary shares and B ordinary shares, never combined into a single ordinary shares line.
- Growth shares: shares that only participate in value created above an agreed hurdle, common in UK management incentive arrangements, entered under whatever class name the articles use, most often growth shares.
- Redeemable shares: shares the company or the holder can require to be bought back on agreed terms, entered under their own class name, with the redemption feature a matter for the wider Form 5471 disclosures rather than for Schedule A column (a) itself.
- Deferred shares: a class with minimal or no current economic rights, often left in place after a restructuring or a down round, still entered as its own row on Schedule A for as long as it remains issued and outstanding.
Alphabet and growth shares: classes with no US analogue
Alphabet shares and growth shares are where preparers most often hesitate, because neither concept maps cleanly onto the common and preferred stock of a US corporation. An A ordinary share and a B ordinary share may carry identical voting and capital rights and differ only in which dividend pool they draw from, a distinction that has no US statutory label. A growth share may carry full voting rights but only a right to capital above a hurdle set by valuation at the date of issue, again a structure built for UK tax-advantaged incentive planning rather than for any comparable US instrument. Column (a) of Schedule A is free text, so there is no wrong answer in a technical sense, but there is a wrong process: the description entered should be the class name the company itself uses consistently in its statutory registers, its statement of capital and any shareholder agreement, not a paraphrase by the preparer of what the class economically resembles. Consistency of the label across every filing, both UK and US, matters more than finding a US-style equivalent term.
Mapping a UK statement of capital to Schedule A
The statement of capital is the document a UK company files with Companies House, required under the Companies Act 2006, that gives a snapshot of its issued share capital at a point in time. A fresh statement of capital is delivered on incorporation, whenever the company allots new shares, whenever shares are cancelled, and again with each confirmation statement unless there has been no change since the last one filed. For each class of share it must state the class name, the total number of issued shares of that class, the total nominal value of that class, and the prescribed particulars of the rights attached to the class, meaning its voting rights, its dividend rights, its rights to capital on a winding up, and whether the shares are redeemable. Companies House will reject a statement of capital that leaves those particulars incomplete or that simply refers the reader to another document. For Schedule A purposes, the class names and share totals on the statement of capital in force at the start and at the end of the accounting period are the primary source for columns (a) and (b).
Using Companies House form SH01 to bridge the gap
Where a company has allotted new shares during the accounting period, the return of allotment of shares, form SH01, is the filing that records the event. Companies House require the class, currency, number of shares allotted and nominal value per share on that form, and the class field is entered as free text by the company itself, which is precisely why the wording used on an SH01 filing should be treated as authoritative when a preparer is choosing how to describe a class on Schedule A. Reading the SH01 filings made during the accounting period, alongside the statement of capital in force at each end of the period, lets a preparer reconstruct the movement in each class: how many shares of a given class existed at the start, how many were allotted, cancelled or transferred during the year, and how many remained outstanding at the end, which is exactly the comparison Schedule A column (b) is designed to show.
Worked scenario: a UK company with four share classes
This is an illustration only, with assumed figures. A US citizen owns and controls a UK trading company through four classes of shares: 100 ordinary shares held since incorporation, 40 A ordinary shares issued to a co-founder at incorporation, 25 preference shares issued to an outside investor two years ago, and a new class of 15 growth shares issued to a senior employee eight months into the accounting period being reported, evidenced by an SH01 filed with Companies House at the time. On Schedule A, the stock table for this company has four rows. Ordinary shares show 100 at the beginning of the period and 100 at the end, unchanged. A ordinary shares show 40 and 40, unchanged. Preference shares show 25 and 25, unchanged. Growth shares show 0 at the beginning of the period, because the class did not exist yet, and 15 at the end, reflecting the mid-year allotment. The class description entered for each row, ordinary shares, A ordinary shares, preference shares and growth shares, is then carried across unchanged to Schedule B column (b) for every US person reported as holding that class.
Reconciling Schedule A to Schedule B: why a mismatch signals an error
Schedule B, U.S. Shareholders of Foreign Corporation, asks for a description of the class of stock held by each US shareholder being reported, and the Instructions for Form 5471 direct that this description should be the same as the description entered on Schedule A column (a). This is not a stylistic preference. A reviewer, whether internal or at the IRS, uses the two schedules together to check that every shareholding disclosed on Schedule B ties back to a class that actually appears, with a matching share count, on Schedule A. If Schedule A lists A ordinary shares while Schedule B for the same company lists Class A shares or A Ord, the two schedules no longer reconcile on their face, even though both descriptions refer to the identical class. That kind of mismatch is one of the most common, and most avoidable, defects preparers see on Form 5471, and the fix is procedural rather than substantive: agree the class names once, from the statutory registers of the company, and reuse that exact wording across every schedule and every filing year.
Shares created or cancelled mid-period
A class that did not exist at the start of the accounting period, because it was created by a new allotment during the year, is still given its own row on Schedule A, with a beginning-of-period figure of zero and an end-of-period figure equal to the shares issued and outstanding at year end, as in the growth shares row in the worked scenario above. The reverse applies where a class is cancelled or fully redeemed during the period: the row shows the number outstanding at the beginning of the period and a figure of zero at the end, rather than being omitted from the schedule altogether. Omitting a class entirely because it existed for only part of the period, or because it was cancelled before the year end, is a common error, since it removes the very movement Schedule A is designed to show the IRS. The underlying Companies House record, whether an SH01 for a new allotment or the updated statement of capital following a cancellation, is the source document that fixes both the class description and the share counts for that row.
Common mistakes on Schedule A
- Combining alphabet share classes into one ordinary shares line instead of giving each class, A ordinary, B ordinary and so on, its own row.
- Using a different class description on Schedule A than the one used on Schedule B for the same company and the same filing year.
- Leaving column (b)(i) blank for a class created during the period, rather than entering zero to show the movement.
- Dropping a class from Schedule A the year it is cancelled, instead of showing the outstanding count falling to zero.
- Translating a UK-specific class name, such as growth shares or deferred shares, into a US-sounding label that does not match the statutory registers of the company.
- Failing to update the class description on Schedule A after the company renames a class in its articles of association, so successive years of Form 5471 filings no longer read consistently.
Where Schedule A fits in the wider Form 5471 return
Schedule A is deliberately narrow: it establishes, class by class, how many shares of a UK company existed at each end of the accounting period, and nothing more. That narrow function still matters, because the class descriptions it sets are then reused on Schedule B to identify who owned what, and the share counts it sets are the reference point against which any change in ownership, any new allotment reported elsewhere in the return, and any percentage ownership calculation for the rest of Form 5471 is measured. Getting Schedule A right starts with the same document a UK company files with Companies House to describe its own share capital, and ends with a Schedule A that a reviewer can cross-check line by line against Schedule B without finding a single description that does not match. For a US person with an interest in a UK company, and particularly one with more than one share class in issue, that consistency is worth building into the annual compliance process from the first year Form 5471 is filed, not retrofitted once HMRC or the IRS asks a question about it.
