What it means
In many countries, responsibility for public services and the power to tax are split between different levels of government. National governments often collect the most lucrative taxes, such as income or sales taxes, while regional and local governments are in charge of services such as hospitals, schools and local roads.
When responsibilities and revenue sources do not line up, there is a fiscal imbalance. Economists describe two main types.
A vertical imbalance is a gap between levels, where the national government has a surplus of revenue and regions face a shortfall. A horizontal imbalance is a gap between governments at the same level, where some regions are rich and others poor, so equal services require different amounts of support.
Governments use transfers to reduce the gaps. These include grants for specific purposes, shared tax revenues and equalisation payments, which top up poorer regions.
The design of these transfers is often debated, because regions that depend on them may have weaker incentives to manage their own finances. The term is also used more widely to mean a long-term mismatch between a government's promised spending, such as pensions and healthcare, and the revenue it is expected to collect.
In that sense, it signals that current policies may not be sustainable without tax increases or reforms. Such projections rely on assumptions about growth, ageing and costs, so they should be read with care.
For businesses and investors, fiscal imbalance matters because it shapes where taxes are raised and who pays them. It affects local government borrowing, the credit risk of regional bonds and the stability of public contracts.
Anyone selling to or lending to a regional government should understand how much of its budget comes from its own taxes and how much is transferred.
In practice
Real-world examples.
Example
A provincial government is responsible for health and education, which make up most of its budget, but it collects only a small part of the taxes. It depends on national transfers to balance its books.
Example
A bond analyst reviewing a regional government's debt notes that 45% of its revenue comes from central government grants. She marks the bonds as exposed to any change in national policy.
Example
A national finance ministry debates a proposal to give states more power to levy taxes. Supporters say this would line up responsibility and revenue, while critics warn it could widen gaps between rich and poor states.
Formula
Calculation
A simple measure of vertical imbalance compares a region's spending responsibilities with the revenue it raises itself.
Vertical gap = Spending responsibilities - Own-source revenue
Gap as % of spending = Vertical gap divided by Spending responsibilities x 100
Worked example: a fictional state is responsible for $40 billion of spending but raises only $30 billion from its own taxes and fees.
Vertical gap = $40 billion - $30 billion = $10 billion
Gap as a percentage of spending = $10 billion divided by $40 billion = 0.25, or 25%
The national government fills this gap through transfers of $10 billion. If the national government cut the transfer to $6 billion, the state would face a $4 billion shortfall to close through higher taxes or lower spending.Case study
Seen in the real world.
Oakland Province is a fictional region with a growing elderly population and rising healthcare costs. Its own tax revenues covered only 70% of what it spent, and the rest came from the national government. When national transfers were frozen for two years, the provincial treasurer faced a growing gap.
In this illustrative case, the province raised a modest sales tax, merged some administrative services and agreed a multi-year deal with the national government that tied transfers to population ageing. The new arrangement gave planners more certainty. The story shows that an imbalance can be managed through a combination of revenue, savings and a clear funding formula.
Watch out
Common mistakes.
- Treating fiscal imbalance as the same as a budget deficit. A government can run a balanced budget and still have an imbalance in which its revenue comes largely from another level of government.
- Assuming that transfers fix the problem permanently. Transfers can change with political priorities, which leaves regional governments exposed.
- Ignoring the horizontal dimension. Even if every region receives the same support per head, differences in costs and tax bases can leave some regions much worse off.
Questions
People also ask.
What is the difference between vertical and horizontal imbalance?
Vertical imbalance is between levels of government, while horizontal imbalance is between governments at the same level, such as two states with unequal wealth.
How do governments reduce fiscal imbalance?
They use grants, shared taxes and equalisation formulas, or they move taxing powers and spending duties so that they better match one another.
Why does it matter to companies?
It influences local tax rates, public spending on infrastructure and the creditworthiness of regional governments, all of which can affect business planning.
