Section 431 elections

It is common where shares are being transferred or issued to employees or directors, for individuals to be asked to complete a section 431 election.

It is common in corporate transactions, where shares are being transferred or issued to employees or directors, for the individuals concerned to be asked (or even required) to complete a section 431 election. The question therefore often arises as to what are s431 elections and why do I need to make one.

Employees and directors (whether executive or non-executive) who subscribe for or acquire shares in the company or any member of the group for which they work, are within the scope of special tax rules applying to employment-related securities.

The rules can also apply to former or prospective employments so, for example, will apply to investors who are to be appointed directors.

The essence of the rules is to prevent employment income or reward being passed to employees or directors (or any persons associated with them) by way of capital returns in relation to shares or securities.

One of the ways this was achieved in the past was by giving employees or directors restricted shares whose value, at the time they were issued, was suppressed by virtue of the restrictions attached to them.

The restrictions would then either fall away or be removed leaving the employee with a much more valuable asset.

Restricted securities

One of the main potential charges under the employment-related security rules therefore relates to restricted securities.

For tax purposes employment-related securities have two values:

  1. Actual market value (AMV) i.e. what the shares are actually worth; and
  2. Unrestricted market value (UMV) i.e. what the shares would be worth if there were no restrictions attaching to them (for example, on the ability to sell or transfer) whether set out in the articles, investment agreement, shareholders agreements or elsewhere.

In very broad terms, unless the “employee” pays the full UMV for the shares as at the time of their acquisition, part of the future growth in value of the shares may fall to be taxed as income rather than capital.

There is always an immediate “general earnings” tax charge to the extent the director/employee does not pay AMV for the shares at the point of acquisition. If the shares are readily convertible assets (which essentially means if they can be easily exchanged for cash) then such income tax will have to be accounted for and collected by the employing company via PAYE and NICs (both primary and secondary) will also be due on the notional payment. If the shares are not readily convertible assets then income tax will need to be reported and paid via the individual’s personal tax return for that tax year and no NICs will be payable.

The director/employee can, however, elect by way of a joint section 431 election with the employing company, to be taxed also at the point of acquisition on any discount between the UMV and AMV. The purpose of a s431 election is to effectively ignore all/some of the restrictions in valuing the shares at acquisition/subscription and treat the shares as having been acquired at their UMV. The definition of restriction is wide and most private company articles contain “restrictions”. If the director/employee does not pay full UMV for any shares that are transferred or issued to them by reason of their employment then, on a subsequent sale, HMRC can seek to levy an income tax charge under the restricted security provisions on a proportion of the growth in value of the shares.

To illustrate, if at the point of acquisition by an employee the actual market value of a share is £1 and the unrestricted market value £1.50 and the employee pays £1 per share there would be no immediate income tax charge (as the employee has paid the AMV) but on a subsequent disposal of those shares 1/3 of the gain could be subject to income tax (as only 2/3 of the UMV was paid up or subject to tax on acquisition).

If however a s431 election is entered into, whilst there would be an immediate income tax charge on the £0.50p discount to UMV (£1.50 less the £1 paid) any subsequent growth in value would not be subject to income tax under the restricted security provisions.

The broad purpose of the election is therefore to treat the shares as having been acquired at their unrestricted market value and try and ensure that any future growth in value of the shares is taxed as capital not income.

It should be noted that there could be a potential downside in making the election if the shares were to fall in value. However, if you expect the shares to rise in value then an election is generally desirable.
