VAT/GST optimization and compliance.

When to Activate

• Structuring transactions to optimize VAT recovery
• Assessing VAT treatment of cross-border supplies (goods and services)
• Implementing reverse charge or use tax mechanisms
• Evaluating whether to form a VAT group
• Dealing with partial exemption and input tax attribution
• Setting up e-commerce VAT compliance (OSS/IOSS)
• Preparing for a VAT audit or managing a VAT refund claim
• Building a VAT compliance calendar across multiple jurisdictions

Core Concepts

VAT Mechanics (Input/Output)

VAT is a consumption tax collected at each stage of the supply chain. The business acts as a collection agent — it charges output VAT on sales and recovers input VAT on purchases. The net amount is remitted to (or refunded by) the tax authority.

• Output VAT: VAT charged on taxable supplies made by the business
• Input VAT: VAT incurred on purchases used for making taxable supplies — fully recoverable if attributable to taxable activities
• Net VAT position: Output VAT minus input VAT. Positive = payment due; negative = refund claim
• Exempt supplies: No output VAT charged, but input VAT on related costs is irrecoverable (e.g., financial services, insurance, healthcare in many jurisdictions)
• Zero-rated supplies: Output VAT at 0%, but input VAT is fully recoverable (e.g., exports, certain food items)

Reverse Charge Mechanism

Shifts the obligation to account for VAT from the supplier to the customer. Eliminates the need for the supplier to register in the customer's jurisdiction.

• B2B cross-border services: General rule — reverse charge applies in the customer's jurisdiction (EU Article 44, Place of Supply rules)
• Domestic reverse charge: Applied in specific sectors to combat fraud (e.g., construction, electronics, metals in EU member states)
• Import VAT deferral: Some jurisdictions allow postponed accounting — VAT on imports declared and recovered on the same return, eliminating cash flow cost

Cross-Border Services (B2B vs. B2C)

• B2B general rule: Taxed where the customer is established — customer accounts for VAT via reverse charge
• B2C general rule: Taxed where the supplier is established — supplier must register and charge local VAT
• Exceptions: Immovable property services (where the property is located), passenger transport (where it takes place), cultural/entertainment (where performed), telecommunications/broadcasting/electronic services (where the consumer is located for B2C)

VAT Grouping

Multiple related entities treated as a single taxable person for VAT purposes. Intra-group transactions fall outside the scope of VAT.

• Benefits: Eliminates irrecoverable VAT on intra-group supplies (especially relevant when one member makes exempt supplies), simplifies compliance
• Risks: Joint and several liability for all group members; administrative complexity on formation/dissolution
• Eligibility: Typically requires financial, economic, and organizational links between entities
• Not available everywhere: Some jurisdictions do not offer grouping; others limit it to specific sectors

Partial Exemption

When a business makes both taxable and exempt supplies, input VAT must be apportioned.

• Direct attribution: Input VAT directly attributable to taxable supplies is fully recoverable; input VAT on exempt supplies is not
• Residual input tax: Overhead costs that cannot be directly attributed are apportioned using a method — typically based on the ratio of taxable to total supplies (turnover-based)
• Special methods: Negotiated with the tax authority to achieve a fairer result (e.g., headcount, floor space, transaction count)
• Annual adjustment: Provisional recoveries during the year are adjusted against the actual annual ratio
• De minimis: If exempt input tax falls below a threshold (e.g., GBP 7,500 per year and less than 50% of total input tax in the UK), full recovery is permitted

E-Commerce VAT (OSS/IOSS)

• One-Stop Shop (OSS): Single VAT registration for reporting B2C supplies of services and intra-EU distance sales of goods. Eliminates need for multiple registrations
• Import One-Stop Shop (IOSS): For goods imported in consignments not exceeding EUR 150. VAT collected at point of sale, goods cleared without import VAT
• Deemed supplier rules: Marketplaces/platforms may be deemed the supplier for VAT purposes — responsible for collecting and remitting VAT
• Threshold: EU distance selling threshold is EUR 10,000 aggregate across all member states — above this, VAT is due in the destination state

VAT Recovery

• Foreign VAT refunds: 8th Directive (EU-to-EU) and 13th Directive (non-EU to EU) refund mechanisms. Strict deadlines — typically September 30 of the following year
• Blocked items: Some input VAT is non-recoverable by law (e.g., entertainment, passenger cars, employee benefits — varies by jurisdiction)
• Time limits: Input VAT must generally be claimed within a fixed period (often 4 years from the supply)
• Supporting documentation: Valid VAT invoice with all required particulars (supplier/customer names, VAT numbers, description, rate, amount)

Compliance Calendar

VAT compliance involves recurring filing obligations that vary by jurisdiction, registration status, and transaction volume.

• Periodic returns: Monthly, quarterly, or annually depending on jurisdiction and turnover
• Intrastat / EC Sales List: Reporting of intra-EU movements of goods and supplies of services
• SAF-T / digital reporting: Real-time or near-real-time invoice reporting (e.g., Italy SdI, Spain SII, Poland KSeF)
• Payment deadlines: Typically aligned with return deadlines, but can differ — late payment triggers interest and penalties

Methodology

1. Transaction mapping: Classify all supply chains by type (goods, services, IP), direction (domestic, cross-border), and customer type (B2B, B2C)
2. Place of supply determination: Apply the correct rule for each transaction type to identify which jurisdiction's VAT applies
3. Rate and exemption analysis: Determine the applicable rate (standard, reduced, zero, exempt) for each supply
4. Input VAT recovery assessment: Identify all input VAT, attribute directly where possible, apply partial exemption method for residual
5. Structure optimization: Evaluate VAT grouping, supply chain restructuring (e.g., flash title arrangements), and import deferral schemes
6. Registration review: Confirm all required registrations are in place; assess whether OSS/IOSS simplifies compliance
7. Compliance framework: Build a calendar of filing and payment deadlines, assign responsibilities, implement controls

Residual (overhead)   | 400       | Mixed           | 82% (*)
                      |           |                 |
Total input VAT       | 1,370     |                 |
Recoverable           | 1,178     |                 | 86%
Irrecoverable         | 192       |                 | 14%

(*) Partial exemption ratio: Taxable turnover / Total turnover = 82%

Optimization options:
  - VAT grouping to eliminate irrecoverable VAT on interco management fees
  - Renegotiate special method based on headcount (estimated recovery: 88%)
  - Review blocked items — some may qualify under capital goods scheme
