How much? The design of tax extraction

This series has examined what counts as economic value. Now we ask: how is it designed?

Design decides direction.

Tax systems do not only decide what to tax. They decide how much, how often, and under what conditions. Rates, thresholds, exemptions, assessment methods.

These are not technical details. They are the architecture of burden.

A tax system can appear balanced on paper while distributing pressure unevenly in practice. The difference lies in design.

Progressive vs Regressive: the direction of rates

A tax is progressive when the rate increases as income or wealth rises. Higher‑income individuals pay a larger proportion of their income, while lower‑income individuals pay a smaller proportion. Personal income tax with graduated brackets is the clearest example, as are well‑designed wealth or property taxes. The core idea is ability to pay: those with more resources contribute more.

A tax is regressive when the effective burden falls more heavily on lower‑income people, even if the rate looks flat. Lower‑income individuals pay a larger share of their income, while higher‑income individuals pay a smaller share. Value Added Tax on basic goods, excise duties on fuel, airtime, and other consumption items, and flat taxes without exemptions all operate this way. The core idea is a consumption‑based burden: everyone pays similar rates, but the impact is unequal.

Progressive taxation has the potential to support equity – but only with intentional design. Regressive taxation often deepens both economic and gender inequality. Progressive redistributes downward and reduces inequality; regressive extracts downward and can deepen it.

The rate is flat. The impact is not.

Presumptive vs Actual: what is measured, what is assumed

Actual taxation is based on recorded income, profit, or assets. It relies on accounts, documentation, and verifiable records. The taxpayer reports what they earned; the system assesses what they owe.

Presumptive taxation is based on proxies. Turnover. Location. Business type. Stall size. Visible activity. The taxpayer does not need to keep detailed accounts. The system estimates liability using observable indicators.

The rationale for presumptive taxation is administrative simplicity. Small businesses and informal operators often lack formal records. Requiring them to maintain accounts would be costly or impossible. Presumptive tax reduces compliance burden. It also ensures that some revenue is collected where traditional assessment cannot reach.

The trade‑off is precision. Actual taxation reflects true profit. Presumptive taxation reflects an approximation. It may over‑tax those with thin margins or under‑tax those with high profits.

Presumption simplifies collection. It also removes precision.

This design choice affects who bears the burden – but that question belongs to the next article.

Exemptions vs Non‑Exemptions: what is protected, what is exposed

Exemptions remove specific goods, activities, or taxpayers from the tax base. They are deliberate policy choices – influenced by power and priorities.

Some exemptions protect low‑income households: zero‑rating basic food, medicine, or sanitary products. Others encourage investment: tax holidays, reduced rates for new factories, or deductions for capital expenditure. Charitable donations and pension contributions are often tax‑relieved. Agricultural inputs like seeds and fertilisers may be exempt to support farming.

Non‑exemptions mean the standard tax rate applies. No special treatment. No reduction. Fuel, cooking oil, sugar, soap, alcoholic drinks, tobacco, soft drinks, luxury cars, electronics, and cosmetics are typically fully taxed. Market fees, trading licences, and local levies are not exempt – small traders pay them daily.

The rationale for exemptions varies. Social exemptions aim to reduce the burden on essentials. Economic exemptions aim to attract investment. Administrative exemptions simplify collection where enforcement costs exceed revenue. The trade‑off is always revenue. Every exemption narrows the tax base. The state must collect the same amount from a smaller base or accept lower revenue. When exemptions favour capital, the burden shifts elsewhere – often onto women.

Taxing sanitary products places a charge on a biological necessity – a design choice with gendered consequences. Taxing cooking fuel and soap falls on the person who cleans and feeds the household, usually a woman. School fees not zero‑rated mean mothers pay more. Market fees and trading licences not exempt hit women in informal trade. Pension reliefs benefit formal workers; informal workers – mostly women – have no pension to relieve. Mortgage deductions benefit property owners; women own less property. Corporate tax incentives reduce revenue, replaced by consumption taxes – which women pay.

The list of exemptions is a map of priorities – priorities shaped by power, influence, and who sits at the table.

Direct vs Indirect: where the system collects

Direct taxes are levied on income, profits, and property. Pay‑as‑you‑earn on salaries, corporate income tax on company profits, property tax on land and buildings. They can be progressive – higher earners pay a higher rate. They reflect ability to pay.

Indirect taxes are levied on goods and services at the point of consumption. Value Added Tax on food, fuel, soap, and sanitary products. Excise duties on alcohol, tobacco, and fuel. Customs duties on imported goods. The rate is constant, but the impact is not.

Governments choose the mix. Direct taxes are harder to collect and easier to avoid. They require records, filings, and enforcement. Indirect taxes are simpler. Every purchase is a point of collection. The poor cannot avoid them.

The trade‑off is equity versus ease. Direct taxes can redistribute; indirect taxes cannot. When a government relies heavily on indirect taxes, it shifts the burden from income and wealth to spending. From those who have to those who have not.

A salaried professional may have deductions, reliefs, and a tax‑free threshold. A market trader pays VAT on every purchase – with no deductions, no reliefs, no threshold. A caregiver who earns no income still pays VAT on the goods needed to feed and clean the household. A woman managing the family budget buys food, fuel, soap, sanitary pads, school supplies. Each purchase carries tax.

Women are more likely to work in informal sectors where direct taxes never reach them. They are more likely to manage household consumption. They are less likely to own property or receive pension reliefs. The weight of indirect taxes falls squarely on daily life.

Indirect taxes shift the burden into survival. Direct taxes, when properly enforced, shift it toward surplus. The choice between them is a choice about who carries the state.

Monetary vs Non‑Monetary: what the system can see

Tax systems are designed to measure what is monetised. Cash income. Wages. Profits. Market transactions. These are visible, recordable, and taxable.

Non‑monetary economic activity is not measured. It generates no cash flow, no receipt, no entry in national accounts. Unpaid care work – cooking, cleaning, childcare, eldercare. Subsistence production – growing food for household consumption. Domestic labour – fetching water, collecting firewood, maintaining the home. Community work – mutual aid, burial societies, local committees.

The rationale is practical. Monetised activity is easier to count. Non‑monetary activity is harder to value. Tax authorities lack the tools to assess it. But the choice to exclude it is also political. What is not counted does not shape tax policy.

The trade‑off is visibility versus value. The system sees what is monetised and regulates it. It ignores what sustains the economy. Yet unpaid care work makes all paid work possible. Subsistence production feeds families when wages are low. Domestic labour reproduces the workforce at no cost to the state.

Gender implications are direct. Women perform the vast majority of unpaid care and domestic work. A market trader’s labour is taxed through VAT and fees; her hours of care work are invisible. A small‑scale farmer’s harvest for home consumption is not income; the same harvest sold at the market is taxed. A caregiver who spends her day nursing a sick relative has no taxable income; her contribution to the economy is zero in official statistics.

When non‑monetary work is ignored, the tax system does not simply leave it alone. It taxes the consumption that care work requires – soap, fuel, food, sanitary products. It taxes the paid work that care work enables – without recognising the subsidy. It treats the unpaid economy as a cost‑free zone while depending on it entirely.

The system taxes what it can count. It depends on what it does not count. That is a design choice with a gender. It is not neutrality.
