Why the VAT group matters for affiliated SMEs
In Switzerland, every legal entity with taxable turnover of CHF 100'000 or more is generally subject to value added tax with its own UID-VAT number and periodic returns. When a holding company, operating company, group real estate entity, or services subsidiary belong to the same shareholder or control structure, transactions between these entities often generate VAT invoices—even though they are internal movements within the business perimeter.
The Federal Act on VAT (LTVA; MWSTG) provides for the so-called group taxation (Unternehmensgruppe): several legally independent businesses can be treated, for VAT purposes, as a single taxpayer. The main effect is neutralisation of VAT on reciprocal supplies between group members, with a single filing responsibility held by the entity designated as the «group representative».
For entrepreneurs, SME CFOs, and fiduciaries, the decision is not only tax-driven: it affects the order-to-cash and procure-to-pay cycle, monthly close, intercompany reconciliation, and how tools such as Accountex record purchases, sales, and internal transfers. This guide summarises current requirements, realistic operational benefits, and accounting choices to document from the application to the Federal Tax Administration (AFC).
Individual registration vs VAT group
Before forming a group, it is worth explicitly comparing what changes relative to separate registration of each company:
| Aspect | Companies registered individually | VAT group (LTVA art. 13) |
|---|---|---|
| VAT taxable person | Each company with its own number and return | A single VAT taxpayer; members are «group parties» |
| Internal supplies | Generally taxable (sales/services between companies) with input tax deduction on the buyer side | Supplies between group members fall outside the group’s VAT scope |
| Periodic return | One per entity; deadlines and checks multiplied | Consolidation on the group representative’s return |
| Liability | Limited to the individual company | Joint liability of members for the group’s VAT obligations (LTVA art. 15 para. 1 let. c) |
| Exports / zero rate | Flow documented per company | Assessment at group level; documentary consistency essential |
| Opting / net tax rate method | Choice per business where permitted | Effective method for the group; the net tax rate method is not permitted with group taxation (OTVA art. 68 para. 2 let. c) |
| Analytical accounting | VAT on every intercompany invoice | Fewer internal VAT items; greater emphasis on clearing accounts and civil-law transfer pricing |
Legal requirements and unified management
A VAT group does not replace a corporate merger: the businesses remain distinct legal persons for company law and direct tax. The AFC registers the group in the taxpayer register only if the conditions of LTVA art. 13 para. 1 are cumulatively met:
Unified management
Members must be linked by unified management of a legal entity (OTVA art. 15): in practice, each member’s conduct is controlled through a majority of votes, by contract or otherwise. Holdings and operating companies common in Swiss SMEs often fit this pattern. Unified management need not belong to the group and may also be based abroad.
Only entities with a registered office, domicile, or business establishment in Switzerland may be group members; the structure must be described clearly in the application.
Group composition
At least two members are required; entities that do not carry on a business and natural persons may also be included (LTVA art. 13 para. 1, reform in force from 1 January 2025). Businesses with exclusively exempt or out-of-scope supplies can complicate eligibility: this must be checked case by case before applying.
The group representative is designated from among members resident in Switzerland or, alternatively, may be a non-member with domicile or registered office in Switzerland (LTVA art. 67 para. 2; OTVA art. 17a); they represent the group vis-à-vis the AFC for returns, corrections, and communications.
- Application to the AFC with written declarations of acceptance by each member, list of members, ownership structure, and desired effective date (as a rule the start of a tax period, except where the VAT ordinance provides otherwise).
- Updates: entries, exits, changes of control, or dissolution of the group must be notified; errors can cause loss of unified treatment with retroactive effect.
- Direct tax: the VAT group does not remove the obligation for documented transfer prices and consolidation eliminations where applicable.
Operational benefits for holdings and operating companies
The «tax» saving from a VAT group is not a rate reduction but the elimination of the cash and administrative effect of VAT on internal supplies. In practice, what most often convinces an SME is back-office simplification.
Liquidity
No more paying VAT on invoices from company A to company B within the same group, followed by recovery as input tax credit. Internal cash flow becomes VAT-neutral.
Administration
A consolidated return reduces reconciliation errors between entities, duplicate deadlines, and fiduciary workload. Separate books per member remain necessary for company law purposes and, for VAT, internal reports to consolidate (OTVA art. 21).
Operational consistency
Centralised services (IT, HR, administration) invoiced to the operating subsidiary integrate better within a single VAT perimeter, provided intercompany prices and contracts are already in order.
Note: supplies to external customers remain normally taxable. Purchases from third-party suppliers remain subject to deduction under the usual rules, but allocation takes place at group level on the representative’s return.
Accounting in SMEs and using Accountex
Under ordinary Swiss accounting (CO art. 957 et seq., GAAP/FER for larger entities), each group member continues to keep its own books. What changes is VAT treatment of internal transactions and the data flow to the consolidated return.
Intra-group transactions
Invoices between group members must not show VAT, as reciprocal supplies are not taxable as transactions between distinct taxpayers. In accounting, net amounts are recorded with intercompany receivable/payable accounts (e.g. account 1300/2300 or equivalent analytical chart) and cost centres per company.
In Accountex, set dedicated VAT codes «non-taxable – VAT group» or use the exemption configured for internal supplies so the VAT module does not incorrectly feed the return. Align configuration across all companies in the perimeter.
Close and filing
The group representative extracts from each set of books the taxable totals, exempt amounts, foreign purchases, and adjustments (self-supply, corrections). Multi-company tools or controlled exports to the fiduciary reduce the risk of double counting.
Document a common closing calendar: delays at one operating company block submission of the group return. Reconcile intercompany balances (open items) periodically regardless of VAT.
Separation of VAT and financial statements
Removing VAT from internal invoices does not remove revenue or expense: the matching principle still applies. For property owned by an SPV and leased to the group, also check any option to tax on leasing (LTVA art. 22) at group level—inconsistent choices between members are not permitted where the law requires uniformity.
Joint liability and common mistakes
The benefit of a VAT group must be weighed against joint liability: each member is liable for the entire group’s VAT obligations, subject to the exception for pension institutions (LTVA art. 15 para. 1 let. c). If an operating company becomes insolvent, the AFC may pursue other entities in the perimeter.
Recurring SME mistakes include: charging VAT on internal supplies after joining the group; failing to notify an acquisition that changes control; attempting to apply the net tax rate method to a VAT group; treating supplies to affiliated businesses not included in the group application as internal.
When a group may not be worthwhile
- Companies with structural VAT credit that benefit from fast refunds as standalone entities.
- A perimeter undergoing major restructuring (spin-off, sale of divisions) in the coming quarters.
- A member with predominantly foreign activity or customs complexity that requires separate VAT numbers for operational reasons.
- Lack of intercompany governance: without contracts and transfer prices, accounting and direct tax risk outweigh the VAT benefit.
Practical steps: from decision to live accounting
- VAT due diligence — map turnover, cross-charges, exports, opting, and property for each company; simulate cash effect over a typical quarter.
- Designation of the group representative — usually the holding or the company with central administrative function; verify capacity to file (or appoint an external representative with a Swiss presence).
- AFC application — include ownership diagram, dates, and UID of all members; agree effective date with your VAT adviser.
- ERP / Accountex update — VAT codes, invoice templates, export consolidation rules; training for those issuing intercompany invoices.
- First group return — cross-reconciliation between companies; archive evidence of unified management and the valid member list for the period.
Summary for entrepreneurs and fiduciaries
The VAT group is a targeted federal instrument: it unifies liability among affiliated companies, eases internal supplies, and concentrates filing obligations. It does not simplify company law or direct tax, and it introduces joint liability that must be managed at group level.
For a Swiss SME with a holding and one or more operating companies, the combination of clear intercompany contracts, a consistent chart of accounts, and correct VAT setup in Accountex turns the VAT group from mere compliance into real efficiency gains. Before submitting the application, tailored advice on your actual flows remains the safest choice—the rules are clear, but practical application depends on each ownership structure.
