What it means
Consumption taxes come in two main designs. A retail sales tax is charged only at the final sale to a consumer, whereas value added tax is charged at every stage of the supply chain, with each business reclaiming the tax it paid on its own inputs.
Both aim to tax the final consumer, but value added tax collects the money in instalments along the chain, which makes it harder to evade. The distinction between collecting a tax and bearing it is the single most useful thing for a non-finance manager to understand.
Value added tax charged to customers is not revenue, and value added tax paid on purchases is not an expense; both sit in balance sheet accounts until the net amount is remitted. Treating the gross amount received as income is a classic way for a small business to spend money it does not own.
The economic argument for consumption taxes is that they tax spending rather than saving or working, which many economists regard as less distorting than high income taxes. The counter-argument is fairness: lower-income households spend a much larger share of their income, so a flat consumption tax takes a bigger proportional bite from them.
Most countries soften this by zero-rating or reducing the rate on essentials such as basic food and children's clothing. Registration thresholds create a practical decision point for small businesses.
Below a certain turnover a business usually need not register, which keeps its prices lower for consumers but stops it reclaiming tax on its own purchases. Crossing the threshold means either absorbing the tax as a margin cut or raising consumer prices, and both options need to be planned for well before the threshold arrives.
Cross-border rules add a further layer that catches out growing businesses. Exports are typically zero-rated while imports are taxed on arrival, and digital services are usually taxed where the customer is located rather than where the seller sits.
A company selling software to customers in several countries may therefore owe consumption tax in each of them despite having no office there.
In practice
Real-world examples.
Example
A cafe registers for value added tax after crossing the turnover threshold and must decide whether to raise menu prices by the full tax or absorb part of it. It absorbs half, accepting a margin reduction, and offsets some of the loss by reclaiming tax on its coffee machine purchase and refit costs.
Example
A software company begins selling subscriptions to customers in four European countries. Because digital services are taxed where the customer is based, it registers under a simplified scheme and files a single return covering all four rather than opening separate registrations.
Example
A logistics business misclassifies a shipment and pays import consumption tax at the standard rate on goods that qualified for a reduced rate. It reclaims the difference through a correction, but only after a three-month delay that leaves $58,000 tied up unnecessarily.
Formula
Calculation
Tax charged = net price x tax rate. Amount remitted under a value added tax = output tax collected - input tax paid.
A furniture workshop sells a dining table for a net price of $200 with value added tax at 20%. The tax charged is $200 x 0.20 = $40, so the customer pays $200 + $40 = $240. The workshop's revenue is $200, not $240; the extra $40 belongs to the tax authority.
The workshop bought timber and hardware for that table at a net cost of $120, paying input tax of $120 x 0.20 = $24. It therefore remits $40 - $24 = $16 to the government. Across the whole chain, the timber supplier has already remitted $24, so the total collected is $24 + $16 = $40, exactly 20% of the final net price the consumer paid.Case study
Seen in the real world.
Kettleworth Brew Company is a fictional craft drinks producer used purely as an illustrative example. In its first two years it stayed below the registration threshold, priced its cans at a level customers liked, and treated all money received as revenue.
Growth pushed it over the threshold mid-year. Suddenly 20% of every consumer sale belonged to the tax authority, and because Kettleworth did not want to raise shelf prices, that came straight out of margin. The finance lead calculated that on a $3.60 retail price the net revenue fell to $3.00, wiping out more than half the contribution per can.
Two changes fixed it in this illustrative account. Kettleworth restructured its pricing so trade customers were quoted net prices with tax shown separately, and it began reclaiming input tax on ingredients, cans and equipment, which it had been unable to do while unregistered. The recovered input tax offset a meaningful part of the hit, and the founders learned to model the threshold crossing a year before it happened rather than the week it did.
Watch out
Common mistakes.
- Recording the gross amount received from customers as revenue, which overstates income and hides a growing liability to the tax authority.
- Assuming a business bears the cost of value added tax, when in most cases it only collects it on the government's behalf.
- Ignoring registration thresholds until they are crossed, leaving no time to reprice or explain the change to customers.
Questions
People also ask.
What is the difference between a sales tax and value added tax?
A sales tax is charged once at the final consumer sale, while value added tax is charged at every stage with businesses reclaiming the tax on their inputs.
Are consumption taxes regressive?
In their pure form yes, because lower-income households spend a larger share of income, which is why many countries reduce or remove the rate on essentials.
Can an unregistered business reclaim tax on its purchases?
No, which is why some small businesses register voluntarily when most of their customers are other registered businesses.
