United Kingdom

Under UK domestic law, a company may have a duty to withhold tax in relation to the payment of either interest or royalties (or other sums paid for the use of a patent). The circumstances in which such a liability arises are discussed below.

There is no requirement to deduct WHT from dividends. Therefore, dividends may always be paid gross, regardless of the terms of the applicable DTT.

Please note, however, that this is not an exhaustive list of all the deductions that might be required to be made in respect of UK tax from payments made to or by companies. In particular, non-resident companies that are subject to UK income tax on UK-source rental profits (see the Taxes on corporate income section for more information) will find their letting agent or tenants are obligated to withhold the appropriate tax at source (currently 20% without any allowances) from their rental payments unless the recipient has first applied and been given permission to receive gross rents under the Non Resident Landlord scheme. Companies are also under an obligation to withhold tax from annual payments. Two other important examples are the UK's deduction at source regime for entertainers and sportsmen, and the scheme under which payments to unregistered subcontractors working on big building projects may need to have tax deducted at source.

Interest WHT

As a general rule, UK domestic law requires companies making payments of interest to withhold tax at 20%. However, there are a number of exceptions to this general rule. The key exclusions are:

• Payments of interest by UK resident companies if the beneficial owner of the interest is also a UK resident company, or a UK PE, provided the interest concerned will be taxed in the United Kingdom as part of the PE's trading profits.
• Payments of interest on a quoted Eurobond.
• Payments of interest paid to or by a UK bank (or a UK PE of a foreign bank).
• Payments of 'short' interest. This is, broadly speaking, interest on loans that will not be in place for more than a year. However, the definition can be contentious, and detailed advice should be taken on this if intending to utilise this exemption.
• Payments of interest that do not 'arise' in the United Kingdom. Whether a payment constitutes UK-source interest is a complex issue, and specialist advice needs to be taken if seeking to use this exception.
• Payments of interest on private placement debts (widely defined) of UK companies.
• Payments of interest that qualify for exemption under the EU Interest and Royalties Directive, for so long as the UK continues to be entitled to benefit from EU Directives following Brexit. Entitlement is currently set to expire on 31 December 2020, but may be extended if a trade deal is agreed.

If none of the exceptions apply, a payment of interest must be made after the deduction of WHT unless (or until) HMRC has given authorisation that the payment may be made gross (or with a reduced rate of WHT) because of the applicability of treaty relief for the recipient.

Royalties WHT

UK domestic law requires companies making payments of patent, copyright, design, model, plan, secret formula, trade mark, brand names and know how royalties that arise in the United Kingdom to deduct WHT at 20%. In addition, there is also the possibility that other royalties that arise in the United Kingdom may also be subject to the same rate of WHT if they constitute 'qualifying annual payments', so specialist advice will be needed to clarify this. However, certain types of royalties, such as film royalties and equipment royalties, will generally not be subject to UK WHT.

In certain circumstances, and subject to certain conditions, royalty payments may be made gross (or with a reduced rate of WHT) where:

• the beneficial owner of the corresponding income is a UK resident company (or trading in the UK through a PE or a partnership in which the partners meet specific conditions); 
• relief is available under a DTT; or
• the EU Interest and Royalties Directive is applicable - for so long as the UK continues to be entitled to benefit from EU Directives following Brexit.  Entitlement is currently set to expire on 31 December 2020, but may be extended if a trade deal is agreed.

Unlike the rule regarding interest, where such a relief is available, a company may make a royalty payment gross of WHT (or subject to a reduced rate of WHT under a treaty) without prior clearance having been given by HMRC if they reasonably believe at the time that the relief is due. However, if that belief is later found to be incorrect, HMRC may direct that the payment must be made net of WHT, with the WHT paid to HMRC, and the payer may be subject to interest and penalties in respect of the WHT that should have been withheld (even if their belief was reasonable).

Double taxation treaties (DTTs)

The tables below set out the rates of WHT applicable to the most common payments of dividends, interest, and royalties under UK domestic law where such a liability arises and the reduced rates that may be available under an applicable DTT. Please refer to specific treaties to ensure the values are up-to-date and ensure you have considered the potential impact of the Multilateral Instrument (MLI). The MLI came into force in the United Kingdom on 1 October 2018. The MLI will have a fundamental impact on how taxpayers access any DTT that both contracting states have opted to be covered by the MLI, subject to the options and reservations both have made in relation to a range of matters (including the date on which it will take effect for particular taxes).

Dividends

There is no requirement to deduct WHT from dividends. Therefore, dividends may always be paid gross, regardless of the terms of the applicable DTT.

Interest

WHT applies only to 'annual interest' (i.e. excluding interest on certain short-term loans). Banks and similar financial institutions are also normally able to pay annual interest to non-UK residents free of WHT. In addition, most of the UK treaties provide for a zero-rate of withholding on interest paid to governmental and quasi-governmental lenders. Such exemptions are not separately indicated in the tables below.

Resident recipients

Note

1. Payments to any UK resident company can be made free of WHT if the recipient is chargeable to tax on the interest or royalty.

Non-resident recipients

Notes

UK domestic law generally charges WHT on patent, copyright, and design royalties, although there can be definitional uncertainties. Many treaties allow reduced rates for a wider range of royalties. These are mentioned in this table, even though there may be no UK WHT applied under domestic law.

1. 3% for news; 5% for copyright; 10% industrial; 15% other royalties.
2. Lower rate for loans from banks and financial institutions.
3. Higher rate applies if recipient controls more than 50% of payer.
4. Lower rate applies to copyright royalties.
5. 0% on loans between businesses.
6. Lower rate applies to industrial, commercial royalties.
7. Specific additional conditions apply for lower rate.
8. Lower rate applies for equipment royalties.
9. Lower rate applies to films, TV, and radio.
10. Higher rate applies to certain profit related interest.
11. Specific conditions apply for higher rate.
