VAT Grouping in 2026: The HMRC Rule Changes UK Multi-Entity Businesses Need to Know

VAT grouping is the UK mechanism that allows two or more entities under common control to file a single VAT return as if they were one VAT-registered business. Intra-group supplies become outside the scope of VAT (so no VAT is charged between group members), and the group as a whole submits one VAT return covering all members. For UK multi-entity businesses, VAT grouping can simplify administration substantially, but it also creates joint and several liability for VAT obligations across all group members. The 2024-25 anti-avoidance changes tightened several aspects of grouping, particularly around partly-exempt groups and offshore members.

This piece walks the grouping eligibility criteria, the recent rule changes, the joint and several liability implications, and the decision framework for whether to group. Sister pieces in the UK VAT registration hub cover the £90k threshold mechanics and voluntary VAT registration for B2B startups.

Who can form a VAT group

A VAT group can include any combination of UK-established corporate bodies (limited companies, LLPs) under common control. "Common control" is typically demonstrated by one body holding more than 50 percent of the voting power in the others, or by one body having the right to appoint a majority of the directors. Holding companies and operating subsidiaries are the classic case. From January 2010, individuals and partnerships (other than LLPs) can also be members of a VAT group, though this is less common.

The grouping benefit

• Single VAT return for the whole group (one set of paperwork, one submission).
• Intra-group supplies are outside the scope of VAT, removing cash flow timing issues on internal transactions.
• Partial exemption calculations are done at group level, often improving the recovery rate.
• Simpler bookkeeping for groups with internal management charges, internal IP licensing, etc.
• One MTD VAT submission flow rather than multiple parallel ones.

The grouping cost

Every member of a VAT group is jointly and severally liable for the group's entire VAT liability. If one group member goes insolvent owing VAT, the other members are pursued for the unpaid amount. For groups with one strong company and several weaker ones, the strong company effectively guarantees the weak ones' VAT. This is the central trade-off of VAT grouping: simplification in exchange for cross-entity liability.

The 2024-25 rule changes

Several significant changes to VAT grouping took effect from 2024 onward:

• Tightened anti-avoidance on partly-exempt groups, particularly where intra-group supplies were being used to manipulate the partial exemption calculation.
• Stricter rules on offshore (non-UK) members of UK VAT groups; in practice most groups can no longer include foreign entities except in narrow circumstances.
• Updated guidance on holding company VAT recovery, clarifying when input VAT incurred at a holding company is recoverable.
• New rules on disposals of group members, particularly the VAT treatment when a member leaves the group mid-quarter.
• Updated treatment of supplies between UK and Isle of Man members of a UK VAT group.

When grouping makes sense

Partial exemption interaction

For groups including any member with VAT-exempt activities (insurance, financial services, education, property rental), partial exemption rules apply to the group as a whole. The "standard method" calculates the recoverable VAT as a percentage based on the ratio of taxable to total supplies. Special methods can be agreed with HMRC for groups where the standard method gives a misleading result. Partial exemption calculation for groups is materially more complex than for single entities; specialist VAT input is typical.

How to form a VAT group

How to leave or change a VAT group

A member can leave the VAT group at any time by giving notice on Form VAT 50/51 (amended version). The member typically separately registers for VAT in its own right from the leaving date. The leaving member remains jointly and severally liable for VAT debts incurred while it was a member, even after leaving. New members can be added to an existing group following the same forms; effective date is the date HMRC accepts the addition.

Common mistakes in VAT grouping

• Including a member that does not actually meet the common control test (the group is then invalid).
• Forgetting that intra-group supplies are out of scope and continuing to issue VAT invoices between members.
• Mis-calculating partial exemption when one member has exempt activities.
• Not updating accounting software to reflect grouping, leading to duplicate VAT returns.
• Underestimating joint and several liability when one member is shaky financially.
• Including offshore entities without checking the 2024-25 restrictions.

Should I group, or keep entities separate?

Default position for most multi-entity UK businesses with fully VATable activity and strong intra-group transactions: yes, group. The admin saving is real, the intra-group VAT removal is genuinely simplifying, and the joint and several liability risk is manageable for stable groups. Default position for groups with exempt activities or mixed UK/offshore structure: model carefully before deciding. The decision typically warrants a 2-3 hour consultation with a specialist VAT accountant who can model the partial exemption interaction and the liability implications.

Does VAT grouping affect MTD VAT compliance?

Yes, but it simplifies rather than complicates. A VAT group files one MTD VAT return rather than several, through the representative member's MTD-compatible software. The underlying bookkeeping can either consolidate into a single accounting file (cleaner) or remain in separate files with consolidation at submission. Most groups using Xero or QuickBooks consolidate at the accounting platform level; larger groups with sector-specific systems sometimes consolidate only at the VAT return stage via Excel or specialist consolidation tools.

What if HMRC challenges the grouping?

HMRC can refuse a VAT group application if it does not meet the common control test, or where it believes the grouping is being used primarily for VAT avoidance. Refusals are appealable through the standard VAT appeals process. HMRC can also disband an existing group that no longer meets the criteria (typically because the common control was broken by a corporate restructure). Maintaining accurate corporate records and notifying HMRC of structural changes promptly avoids these issues.
