VAT basics for small product businesses

VAT causes more avoidable trouble for small product businesses than any other tax, and rarely because the concept is hard. It causes trouble because the money sits in your bank account for weeks looking exactly like revenue, and because the rules change the moment you sell across a border.

The mechanism

VAT is a consumption tax collected in stages. Each business in a chain charges VAT on what it sells, reclaims VAT on what it buys, and remits the difference. The end consumer, who cannot reclaim, bears the whole amount.

VAT payable = output VAT charged on sales - input VAT paid on purchases

A workshop buying materials and selling finished goods, at a 19% rate:

The EUR 285 is 19% of the EUR 1,500 of value the workshop added. That is the whole design of the tax, and it is worth internalising because it explains everything else: VAT is neutral for registered businesses in the middle of a chain, and it is neutral only if the paperwork works.

When registration becomes compulsory

Thresholds are national and the range across the EU is wide — some Member States require registration from the first euro of turnover, others set the bar in the tens of thousands. There is no single European figure, so the only reliable answer is your own country's.

Beyond your domestic threshold, three situations commonly force registration regardless of size:

• Making intra-Community supplies of goods to businesses in other Member States
• Receiving certain cross-border services where you must account for the tax under the reverse charge
• Exceeding the EU-wide threshold for distance selling to consumers in other Member States

Since January 2025 there is also an EU-wide SME exemption scheme, which allows a qualifying small business to apply a VAT exemption in Member States other than the one where it is established, subject to national thresholds and an EU-wide annual turnover limit. It is genuinely useful for small cross-border sellers, and it has conditions and a separate identification requirement — worth asking your accountant about specifically rather than assuming it applies.

Voluntary registration is sometimes worth it below the threshold. It lets you reclaim input VAT on materials and equipment, which suits a business selling mainly to other registered businesses. It is usually a poor idea if you sell to consumers, because you must then add VAT to prices the market already set.

Rates

Every Member State sets its own rates within EU limits: a standard rate of at least 15%, and reduced rates of at least 5% on a defined list of goods and services, with some historical exceptions permitting lower or zero rates.

For product businesses the classification questions that recur are food and drink, children's items, books and printed matter, and anything medical or hygienic. These are decided by national law and the boundaries can be genuinely fine — the same physical item can attract different rates depending on presentation, ingredients, or intended use. If a meaningful share of your revenue sits near a boundary, get a written view from your accountant once and store it with the product record. Retrospective reclassification of several years of sales is an expensive way to learn the answer.

Selling into another EU country

To a business (B2B)

Goods dispatched to a VAT-registered business in another Member State are generally zero-rated as an intra-Community supply. The customer accounts for the VAT in their own country under the reverse charge. Three conditions do the work:

• The customer has a valid VAT identification number in another Member State — validate it through the VIES system and keep the confirmation.
• The goods physically leave your country, and you hold evidence of transport.
• The invoice carries the customer's VAT number and the required reverse-charge wording, per the EU invoice requirements.

Fail any of them and the supply can be treated as domestic, leaving you liable for VAT you never charged. Validate at the time of supply, not at the year end, and store the validation result — a number that was valid in March is not evidence about a sale in November.

You will also normally file an EC Sales List reporting these supplies by customer VAT number.

To a consumer (B2C)

Cross-border sales of goods to consumers in other Member States are governed by a single EU-wide threshold of EUR 10,000 per year, covering distance sales of goods and certain digital services combined.

• Below EUR 10,000 total across all Member States: you may charge your own domestic rate.
• Above it: you must charge the VAT rate of the customer's country, on every such sale.

The threshold is aggregate, not per country, and it is low enough that a modestly successful online shop crosses it without noticing. Track cross-border consumer sales as a running total from the start of the year — finding out afterwards means correcting rates retrospectively on sales already made at the wrong price.

The One Stop Shop

Once over the threshold, charging each customer's national rate does not mean registering in each country. The Union One Stop Shop lets you register once in your own Member State and file a single quarterly return covering all your EU B2C distance sales, with the tax authority distributing the money.

The obligation OSS creates is operational: you must apply the correct rate for each destination country and product category at the point of sale, and keep records for ten years. Rate tables change. Handling this in a spreadsheet is possible for a handful of countries and becomes a liability as the list grows.

For goods imported from outside the EU in consignments up to EUR 150, the Import One Stop Shop works similarly, letting you charge VAT at the point of sale rather than leaving your customer to pay it — plus a handling fee — on delivery.

What you can and cannot reclaim

Input VAT is deductible where the purchase is used for making taxable supplies. Recurring exceptions:

• Business entertainment — generally blocked.
• Passenger cars — usually restricted, with national variation.
• Mixed-use items — apportion, and document the basis.
• Exempt activities — input VAT attributable to them is not deductible, and businesses with both taxable and exempt supplies must apportion.
• Anything without a valid invoice — no compliant invoice, no deduction. A bank statement is not evidence.

That last one is the most common practical loss. Missing supplier invoices are simply money given up, and the time to collect them is at the point of purchase.

The cash flow trap

This is where VAT actually damages small businesses. You charge VAT at invoice, you generally owe it by reference to the supply date, and your customer may pay you 60 days later. On standard accruals accounting you can be remitting VAT on invoices you have not been paid for.

On EUR 40,000 of monthly sales at 19%, roughly EUR 7,600 a month passing through the account is not yours. Over a quarter that is EUR 22,800 due on one date. A business that has treated it as working capital will feel that as a sudden crisis, and it was entirely predictable.

Three defences, in order of effectiveness:

• Put the VAT date in the 13-week cash forecast as a hard commitment, alongside payroll. Covered in why a profitable workshop runs out of cash.
• Ask about a cash accounting scheme. Many Member States offer one below a turnover limit, accounting for VAT when payment is received rather than when invoiced. For a business selling on credit terms this can transform the position.
• Set VAT aside as it is collected, in a separate account. Unsophisticated and highly effective.

Records and returns

Filing frequency is national — monthly or quarterly is typical, sometimes annually for small businesses. Whatever the frequency:

• Keep every sales and purchase invoice for the national retention period, commonly six to ten years.
• Record VAT separately by rate, so the return is a report rather than a reconstruction.
• Keep evidence of transport for every intra-Community supply.
• Keep VIES validation results with the customer record.
• Reconcile the VAT control account to the return every period — a persistent difference means something is being recorded inconsistently, and it is far cheaper to find it now.

The reason to have this fall out of ordinary transaction records, rather than being assembled each quarter, is not tidiness. It is that a VAT return built by hand from several files is a return nobody can check, and errors in it compound quietly until an audit finds them all at once.
