Brexit – Corporate Tax Implications for EU-UK Trading Relationships

Content Team10 minute read18 Aug 2021


The majority of 2020 was spent in a transition period between the UK and European Union, in which the EU laws continued to apply to the UK. Therefore, nothing changed for most aspects of businesses.

But the UK’s departure officially came into force from January 2021 onwards. This means businesses will be hit with several impacts, including implications and compliance for taxation, especially corporation tax following Brexit.



‘Brexit’ is a contraction of ‘British exit’, which is used to define the UK’s departure from the European Union.

1. Overview of Brexit’s impact on UK businesses

One of Brexit’s significant impacts is the UK’s new status as a third country, or non-EU country, and the release from all obligations under EU legislation.

Consequently, companies incorporated in the UK are not covered by Article 54 under the Treaty on the Functioning of the European Union.

This means EU Member States are not required to recognize the legal personality (and limited liability) of those UK companies incorporated within the Member State.

Following Brexit, new laws are applied to sales between the UK and the EU. This change might have an impact on your tax processes if you are one of the following:

  • A UK business – your business is located in the United Kingdom.
  • An EU business – your business is located in a European Union member country other than the United Kingdom.
  • A non-EU business – your business is located in a country outside of the UK and the EU.

Post-Brexit also results in the loss of EU fundamental freedoms and taxation directives with respect to the UK, which leads to additional tax costs for businesses and individuals.

Along with new fundamentals and directives, needed adaptation and additional paperwork are also rising for business owners.

The following section will highlight some of the changes in UK taxation that commonly arise in the post-Brexit period.

2. UK’s corporate tax changes after Brexit

Although the UK corporation tax rate remains unchanged at 19%, UK businesses still suffer from other fundamental changes in terms of taxation. Hereafter, we have captured some of the most relevant items for you to consider.

2.1. Indirect taxes

As most of the indirect taxes are EU-based, they are generally more influenced by Brexit than direct taxes.

Below are indirect taxes that need to be considered by business owners.

  • Value Added Tax (VAT)

After Brexit, the UK is no longer part of the EU VAT area. With a customs border between the EU and the UK, moving goods is considered importing and exporting. For most goods and services, the VAT standard rate is set at 20%.

The sale of goods from the UK to the EU has officially become exports (the sending of goods from a country to outside) rather than dispatches (the sending of goods between EU state members).

On the other hand, the transaction of goods from the EU to the UK has become imports (the receipt of goods into a country from outside) rather than acquisitions (the receipt of goods between EU state members).

(1) VAT for goods imports

Businesses across the world that import goods into the UK can implement a method called postponed VAT accounting.

This system aims to delay the payment of import VAT to avoid a negative impact on the business’s cash flow.

Before Brexit, commercial goods over £135 importing to the UK would be held at customs until the import VAT is paid. With the postponed VAT accounting, businesses do not pay the VAT immediately but record the import VAT on their VAT Return.

Companies using this method need to declare that they postpone the VAT on customs clearance paperwork, and include the VAT registration number (VRN).

(2) VAT on service

For purchasing services, rather than goods cross-border, things are similar to before Brexit.

Under the place of supply rules, business to business (B2B) transactions of services are subject to tax in the country of the customer and administered through reverse charge, with some exceptions.

Business to consumer (B2C) transactions are subject to tax in the country of the seller, also with some exceptions.

(3) VAT on export

The VAT situation has changed for exporting. Exports to EU countries are now treated like those to non-EU countries, meaning they should be zero-rated for UK VAT.

A zero percent VAT rate is applied. No VAT is payable but businesses still have to include the exports as part of VAT accounting. This is obliged regardless of the type of business (B2C or B2B).

(4) VAT on imports £135 and under

Following Brexit, the UK introduced additional measures for overseas goods arriving from outside the UK.

One of the most impactful factors related to imports of goods equal to or less than £135, the new rules are as follows:

• Low-Value Consignment Relief or LVCR has been eliminated. Previously, imports with a value below £15 are exempted from import VAT.

• VAT on imports with a consignment value equal to or less than £135 has VAT applied at the point of sale, rather than applied as import VAT at customs.

For B2C transactions, this UK VAT will be charged and collected by the seller but for B2B transactions, the VAT is reverse charged to the customer.

  • Customs duties

All trade between the UK and the EU are recognized as imports and exports, and thus are subject to customs duties.

Fortunately, the UK secured a trade deal that allows UK businesses to continue custom-free trade with EU neighbors (the Trade and Cooperation Agreement or TCA).

To be qualified for custom-free trading, UK companies need to comply with ‘preferential treatment’ under the terms set out in the TCA.

Preferential treatment means there won’t be any customs duties or limits to the number of goods that can be imported or exported between the UK and EU, under conditions of ‘rules of origin’.

Rules of origin indicate that business owners must demonstrate where their goods were made – and where the components in those products come from – to determine whether tariffs are levied on goods into the EU or UK. Goods that do not comply with rules of origin will be bound to standard tariffs imposed by the UK (the UK Global Tariff) and EU (Common Customs Tariff) respectively.

Businesses must also apply for an Economic Operator Registration and Identification number (EORI) to continue trading within the EU continent.

UK businesses could face customs burdens selling to certain EU countries. The impact will depend on the company’s sector, and vary from product to product.

2.2. Direct tax

Unlike indirect taxes, direct taxes are outside the competence of the EU, but this does not mean that there are no significant consequences.

The key change is that the UK is no longer a qualifying jurisdiction in the context of EU directives. 

This particularly affects direct tax rules, especially in relation to cross-border dividend tax relief, payment of interest and royalties, as well as cross-border mergers.

In particular: 

  • Parent/Subsidiary Directive (PSD)

Any cross-border distributions of dividends with EU companies are now subject to withholding tax (WHT).

For example, payments from an Italian branch to a UK parent establishment, which previously relied on the PSD to be exempted from withholding tax, may now suffer withholding at 5/15%.

  • Interest and Royalties Directive (IRD)

The payments of annual interest and royalties from companies located in the EU will be subjected to withholding tax starting from 1 June 2021.

This will potentially cause both UK and EU businesses to account for WHT on the payments made.

The tax payment of interest and royalty between the EU and the UK will be dependent upon the EU Member States domestic law and the relevant tax treaty between that Member States and the UK.

  • EU Merger Tax Directive

Capital gains tax will be applied on certain cross-border mergers, divisions, transfers of assets, and exchanges of shares between companies between UK and EU companies.

3. UK’s corporate accounting changes after Brexit

UK businesses have experienced several changes to the corporate reporting regime after Brexit.

3.1. Accounting for UK company

UK companies previously chose whether to produce their accounts using the UK Generally Accepted Accounting Practices (UK GAAP) or International Accounting Standards as endorsed by the EU (EU IAS).

However, after Brexit, all UK companies need to adapt to the UK-adopted International Financial Accounting Standards (UK IAS) instead of EU IAS from January 2021 onwards.

Both UK and EU standards are generally the same, but differences can occur later if the UK and the EU take different approaches to future amendments.

UK parent establishments with a presence in the European Economic Area (EEA) (e.g. a branch) need to check the reporting requirements in the relevant EEA country.

3.2. UK company with a European Economic Area (EEA) listing

The company will produce accounts in regards to the UK Companies Act 2006 for domestic filing purposes.

Additionally, the company has to comply with regulatory requirements in the jurisdictions where it is listed and publishes accounts using EU-adopted IAS as issued by the International Accounting Standards Board (IASB).

3.3. UK subsidiary with an EEA-registered parent

After Brexit, UK subsidiaries with EEA parent companies are not eligible for certain exemptions from filing accounts anymore. The UK subsidiaries are now required to prepare and file accounts annually with Companies House.

4. Corporate law changes for business after Brexit

As much as Brexit represents a critical shift in EU-UK corporate tax implications, it also poses a significant impact on corporate law. It is vital to make sure that your business is aware of these changes to not get caught out.

These changes normally affect businesses that have a cross-border relationship with the EU, including

  • A business conducts operations in the EU;
  • An EU company or individual operating in the UK; or
  • A UK branch with an EEA parent.

Below are some changes in corporate law that we think are relevant to your business

4.1. Filing and disclosure changes

The following companies must file additional information to Companies House:

  • UK companies with EEA corporate officers; and
  • EEA companies with a registered UK establishment.

An EEA company with a registered UK establishment is also required to disclose additional public-facing information, such as website, letterhead, and order forms.

4.2. Freedom of establishment

Since the UK has become a “third country” for EU law purposes, it loses the rights to freedom of establishment within the EU. Therefore, UK businesses can only establish themselves within the relevant law regime of each Member State.

UK companies operating in the EU need to restructure to comply with legal requirements in the relevant EU Member States.

4.3. Appointment of a fiscal representative

UK companies operating in the EU need to register for EU VAT and appoint fiscal representatives in accordance with the requirements of the countries where they sell.

Fiscal representatives are local companies or persons who represent your business in dealing with the local tax authorities regarding tax reporting and VAT debts.

In some EU member states, it is a must for UK companies to have a fiscal representative. Companies that fail to appoint a fiscal representative are heavily punished by local tax authorities.

4.4. Registration of new EORI

An Economic Operator Registration and Identification Number, or EORI, is an ID number used to register and track customs authorizations, approvals, and decisions.

Previously, one EORI could be used for tax authorities in both the UK and other EU member states. After Brexit, businesses are required to have a separate UK and EU EORI number.

It is advised for businesses to consult with local tax authorities to know whether they need a new EORI number.

Incorporate your business in the UK post-Brexit


  • Leaving the EU gives the UK greater control over its law and trading regulations without the constraints from EU policies.
  • Businesses have more freedom to trade with other major economies such as Japan, India, and the US.
  • The UK is now free from the slow and inflexible bureaucratic system of the EU, making it more favorable for SMEs and startups to do business.


  • Doing business between the UK and the EU is understandably more complicated after Brexit.
  • Business owners operating across borders are now facing increased inspections and regulatory burdens, which eventually slow down the trading activities and cost more.

The UK remains one of the most ideal business destinations for entrepreneurs. If you are looking to incorporate your business in the UK, BBCIncorp experienced consultants are always available to assist you.
