Consumption tax: taxing spending, not income

Updated: July 2026

A consumption tax is any tax on spending rather than on earning. Work and save and it leaves you alone; spend and it takes its cut. VAT is the biggest member of the family, but Ireland runs several side by side, and seeing them together explains a surprising amount about Irish prices.

The family members in Ireland

• VAT: the broad-based one, on most goods and services at the five Irish rates.
• Excise duties: targeted per-unit taxes on alcohol, tobacco, and fuels, charged on quantity rather than price. A pint carries excise before VAT is calculated on top, which is a tax on a tax and entirely deliberate.
• Carbon tax: a per-tonne charge on fossil fuels, rising on a legislated schedule, again with VAT applied on top.
• VRT on vehicle registration and stamp duty on property transactions are transaction taxes with a strong consumption flavour.

The case for taxing spending

Economists tend to like consumption taxes because they do not punish saving or investment the way income taxes can, they are hard to avoid at scale, and revenue is remarkably steady: people keep buying groceries through recessions that flatten income tax receipts. VAT delivers those properties across a broad base, which is why it funds roughly one euro in five of Irish government spending.

The case against, and Ireland's answer

The standing objection is regressivity: a household spending everything it earns pays consumption tax on all of it, while a household saving half pays on only half, so the burden falls proportionally harder on lower incomes. Ireland's structural answer is the unusually broad zero rate on most food, children's clothing and oral medicines, which strips the tax from the goods that dominate low-income budgets, and the reduced rates on necessities like home energy. Whether that answer goes far enough is a live political argument, and honestly the evidence runs both directions depending on what you measure spending against.
