What it means
Every government has to pay for things such as schools, roads, healthcare and security. How much it can raise from taxes and other sources, without damaging the economy, is its fiscal capacity.
A region with high incomes and many profitable businesses has a larger tax base than a poorer region, so it can raise more at the same tax rates. Capacity is not only about wealth.
It also depends on the strength of tax administration, the extent of the informal economy where activity goes untaxed, the legal system and how willing people are to comply. A country with a modest income but an efficient collection system can have greater capacity than a richer country that struggles to collect taxes.
Fiscal capacity matters in federal systems, where national governments often give grants to regional governments to help even out differences. A poorer province may need services as costly as those of a wealthy one, but it has less tax base to pay for them.
Transfer formulas often use a measure of capacity to decide how much each region receives, which is called fiscal equalisation. Investors and credit analysts examine fiscal capacity when judging the risk of lending to a government.
A state with strong capacity can raise taxes or cut spending to meet its debts, which supports its credit rating. Weak capacity means less room to cope with shocks such as a recession or a natural disaster.
For businesses, the concept explains why tax rates and public services vary across locations. It also helps in judging how stable local infrastructure, payments to suppliers and incentives might be over the long term.
A government with limited capacity may delay payments or raise charges when budgets are tight.
In practice
Real-world examples.
Example
A national government compares the tax base of each of its provinces. Provinces with a lower per-person capacity receive larger grants so that residents have access to similar public services.
Example
A credit analyst reviews a city's bonds and finds that the city relies on one large employer for most of its tax revenue. She concludes that fiscal capacity is fragile and recommends a higher risk premium.
Example
A development agency helps a low-income country modernise its tax collection systems. Raising collection from 12% of national income to 15% increases the government's ability to pay for schools without increasing tax rates.
Formula
Calculation
A standard way to measure fiscal capacity is to apply a common, representative tax rate to the region's tax base.
Fiscal capacity = Tax base x Representative tax rate
Fiscal capacity per person = Fiscal capacity divided by Population
Worked example: a region has a taxable income base of $50 billion, and the representative tax rate used for comparison is 10%. Its population is 2,500,000.
Fiscal capacity = $50,000,000,000 x 10% = $5,000,000,000
Per person = $5,000,000,000 divided by 2,500,000 = $2,000
If a neighbouring region has the same population but a tax base of only $30 billion, its capacity is $3,000,000,000, or $1,200 per person. The difference of $800 per person is the kind of gap equalisation payments try to narrow.Case study
Seen in the real world.
Highlands County is a fictional rural county with a small tax base but a large road network to maintain. Its budget officer calculated that, at the state's average tax rates, the county could raise only $1,100 per resident while the state average was $1,900. The gap meant fewer resources for the same obligations.
In this illustrative case, the county applied for state equalisation funding and also invested in a business park to broaden its base. Within eight years its capacity per resident rose to $1,500 and the equalisation grant was reduced. The case shows that capacity can be improved through growth and better administration, not just by raising rates.
Watch out
Common mistakes.
- Confusing fiscal capacity with actual revenue. Capacity is the potential to raise money at standard rates, while actual revenue depends on the rates and effort the government chooses.
- Assuming that high rates mean high capacity. Very high rates can shrink the tax base, because people and businesses move or avoid tax.
- Ignoring spending needs. A region may have decent capacity but still face a shortfall if its costs, such as an ageing population or difficult geography, are unusually high.
Questions
People also ask.
How is fiscal capacity different from fiscal need?
Capacity is what a government can raise, while need is what it must spend to provide a standard level of services. The gap between them drives equalisation payments.
Can a government increase its fiscal capacity?
Yes, by growing the economy, widening the tax base, improving tax collection and reducing evasion and the informal economy.
Why do rating agencies care about it?
It shows how much room the government has to raise funds in a crisis, which affects its ability to repay debt.
