Retail tax adviser: manage the tax of multi-channel selling

Retail taxation in the multichannel era: complexity that is here to stay

Digitalisation of commerce has created new tax complexity affecting all retail businesses. Companies selling across multiple channels — physical store, own website, Amazon, European marketplaces — must simultaneously manage different VAT regimes, different filing obligations, and different liability rules depending on the channel.

At BMC we advise retail and consumer goods businesses of all sizes: from the DTC (direct-to-consumer) brand selling exclusively online to the multi-city bricks-and-mortar retailer with a growing e-commerce operation.

The OSS: simpler in principle, demanding in practice

The EU OSS regime allows businesses selling online to consumers in other EU member states to declare and pay all of that VAT through a single quarterly return submitted to the AEAT. In theory it greatly simplifies management; in practice it requires knowing the correct VAT rate in each member state for each type of product sold, since EU VAT harmonisation is incomplete and reduced rates vary between countries.

We handle OSS registration, prepare quarterly declarations, and calculate the VAT by country, ensuring the rates applied are correct for each product and market.

E-commerce with non-EU suppliers: dropshipping and marketplaces

The VAT rules for e-commerce with a non-EU dimension changed fundamentally from July 2021. Marketplaces facilitating sales by non-EU suppliers to EU consumers are now liable for the VAT on those sales, with significant implications for Spanish platforms operating this model. For businesses using dropshipping with Chinese or other non-EU suppliers, managing import VAT and correctly reporting the sales is a high-risk tax area.

We advise on the VAT flow analysis in each business model and on designing the controls needed for correct compliance.

Loyalty programmes and vouchers: the detail that matters

Loyalty points programmes, discount vouchers, and gift cards are common commercial instruments in retail whose tax treatment is more complex than it appears. The issue of the voucher, the VAT point, the treatment of unused expired vouchers, and the taxable amount when a discount voucher is applied are technical matters that regularly generate errors in VAT returns.

VAT compliance for physical retail: Spain-specific rules

Physical retail faces VAT compliance requirements beyond the standard quarterly Modelo 303. Multi-location retailers must aggregate all transactions across locations, with correct application of reduced rates by product type (10% for most food, 4% for basic staples, 21% standard), exemptions, and the treatment of in-store gift cards and deposit systems.

The simplified VAT regime (régimen simplificado). Available to retail businesses with turnover below €250,000, this regime replaces actual VAT tracking with an objective-module system. It reduces accounting burden but may not be most efficient for businesses with high input VAT. Election must be made in January for the following year.

Cash accounting scheme. The IVA cash accounting scheme (criterio de caja) defers VAT payment until customer payment is received — useful for retailers with extended credit terms to wholesale customers. Clear payment-method record-keeping is required.

Corporate Income Tax incentives for retail companies

Retail companies are often unaware of the full range of corporate tax incentives available to their sector. Key incentives that apply frequently to retail businesses:

Equalisation reserve (reserva de nivelación). Available to SMEs under €10 million in turnover, this measure allows a deduction of up to 10% of taxable income to create a reserve that compensates future tax losses. It is a 5-year tax deferral at no interest cost — effectively free working capital from the tax system.

Free depreciation. Tangible assets acquired by SMEs can be freely depreciated in the year of purchase (subject to headcount maintenance). For a retailer investing in shop fit-out, equipment, or vehicles, this allows the full deduction in year one rather than over 10-15 years of standard depreciation.

Training deductions. Expenditure on employee training that improves digital skills or labour market adaptability qualifies for a 100% deduction (200% for expenditure exceeding the prior two-year average). Retail sector digital skills training — e-commerce platforms, CRM systems, digital payment tools — routinely qualifies.

AEAT inspections in retail: common triggers

Retail sector AEAT inspections most commonly arise from: cash transactions without electronic payment trail (particularly in food retail and hospitality-adjacent formats), discrepancies between declared revenue and third-party data (credit card terminal revenue reported by banks versus declared VAT income), and inconsistency between staff headcount (reported to Social Security) and declared revenue per employee. BMC’s retail tax advisory service includes a proactive risk assessment of these exposure areas.

Corporate tax planning for retail companies

Retail companies have specific corporate tax planning opportunities that sector-specialist advisors identify and pursue systematically:

Store opening costs and pre-trading expenses. Pre-opening costs — lease fitting-out, staff recruitment and training before the opening date, marketing launch expenses — are deductible as expenses in the year incurred, not capitalised and amortised over the lease term. Ensuring pre-opening costs are correctly classified at the outset avoids later disputes with AEAT over the timing of the deduction.

Operating leases on commercial premises. Since the adoption of IFRS 16 accounting treatment in the full PGC (from 2021), retail companies with significant long-term store leases must recognise a right-of-use asset and a lease liability on the balance sheet. The tax treatment diverges from the accounting treatment: lease payments continue to be deductible as expenses for Corporate Income Tax purposes (under Spain’s tax-specific leasing rules), creating a deferred tax liability that must be tracked and disclosed.

Inventory valuation. The choice of inventory valuation method — FIFO, weighted average cost — affects both reported profits and the Corporate Income Tax base. In inflationary periods (high COGS due to rising input costs), the weighted average method produces lower profits and lower corporate tax. The method must be consistent and documented; changes require AEAT notification.

Online platform marketplace VAT collection. For retail companies selling through Amazon, Zalando, or other EU marketplaces, the marketplace operator is responsible for collecting and remitting VAT on B2C sales since July 2021. This creates a certification requirement: the retailer must confirm its VAT status (business seller versus private seller) and the marketplace must receive this status annually. Ensuring accurate VAT status registration with each marketplace platform prevents over-withholding of marketplace revenues.

Working capital and tax cash flow management

Retail businesses’ working capital cycles create specific opportunities for tax cash flow optimisation. Quarterly VAT positions can be managed through:

Monthly VAT return regime (REDEME). High-volume retailers with significant input VAT (store refurbishments, capital investment) can apply for monthly VAT refund registration, converting quarterly credit positions into monthly cash. The trade-off — inclusion in the SII real-time invoicing ledger — is manageable for companies with existing ERP systems that can generate the required API feeds.

Customs duty and import VAT deferral. Importers bringing inventory from non-EU suppliers can apply for customs duty deferral through a customs warehouse or simplified declaration regime, improving cash flow on the customs duty and import VAT that would otherwise be payable on each shipment. BMC advises on the customs planning aspects of retail sourcing strategy in conjunction with the tax advisory.

Franchise models and multi-format retail structures

Retail groups that have grown through franchising face a specific set of tax and compliance issues at the intersection of the franchisor-franchisee relationship and the standard retail compliance framework.

Royalty income for the franchisor. Royalties received by a Spanish franchisor from franchisees — based on a percentage of franchisee revenue — are corporate income subject to standard IS rates. If the royalties relate to intellectual property developed by the franchisor (branding, operating systems, proprietary technology), the patent box regime may apply, providing a 60% exemption on qualifying royalty income.

VAT on franchise fees. Initial franchise fees and ongoing royalties are subject to VAT at the standard rate of 21% when charged within Spain. Royalties charged to franchisees in other EU member states are B2B services taxed where the recipient is established — the franchisee accounts for VAT under the reverse charge. For non-EU franchisees, royalties are outside the scope of Spanish VAT. The correct treatment of each royalty flow must be determined based on the franchisee’s location and VAT status.

Withholding tax on royalties. Royalties paid by a Spanish franchise operator to a non-resident franchisor are subject to 24% IRNR withholding under Spanish domestic law, reduced by the applicable double tax treaty. The EU Interest and Royalties Directive eliminates withholding on royalties paid to EU-resident associated companies. For non-EU franchisors (US, UK post-Brexit, LATAM), treaty-reduced rates apply where available.

BMC advises Spanish franchise groups on the complete tax framework of their model — from the initial franchise agreement drafting to the ongoing compliance management of royalty flows, VAT treatment, and withholding obligations across all franchisee jurisdictions. For international franchise networks expanding into Spain, we provide the initial setup advisory and connect with the franchisor’s home-country advisors to ensure that the Spanish tax structure is coherent with the group’s overall transfer pricing and royalty policy. We also advise franchisors on the Spanish withholding tax obligations for royalties paid from Spain to non-resident franchisors and on the treaty-based reduced rates available under Spain’s network of over 90 double tax treaties — ensuring that franchise royalty flows are tax-efficient and compliant across all relevant jurisdictions from the outset of the franchise relationship.
