JH: Tax & Expenditure Incidence in Peru
The Questions
1. Who bears the burden of taxes?2. Who benefits from government
spending?3. What are the net effects?4. Who would gain/lose under different
possible tax reform packages, and by how much?

Example 1: Peru: Tax Revenue Central government tax revenue
11.6% of GDP in 2004 Buoyant since 2002 71% of revenue from indirect tax
▪ Vat: 19% rate; but yields just 4.9% of GDP Income tax: 3.4% of GDP

Vietnam: Main taxes (% of GDP)
Corporate income tax, 7.96
Individual income tax, 0.60
Value-added tax, 7.11
Excise taxes, 1.46
Natural resources tax, 1.44
Taxes on trade, 1.93
Fees, charges, and non-tax revenues,
2.36
Grants, 0.00
All other taxes, 0.91
Vietnam: Noteworthy trends
Revenue/GDP: 20% to 2000, now 25% VAT: 7% of GDP (at 10% rate!) Trade: from 4% to 2% of GDP, despite
explosion of imports All income tax: Peaked at 10% GDP in
2006, but dependent on SOE sector NB: PIT raises 2% of revenue;
surprisingly, not rising

Measuring Incidence (1)
Step 1. Make assumptions about incidence Statutory incidence ≠ Effective
incidence See Table
May 11, 2011 Page 8
Incidence assumptions VAT: on consumers Excises: on consumers PIT: on earners Business profits: on earners Other taxes:
▪ Property transfer; local fees and contributions: on payers.
▪ In this study, CIT, trade taxes, natural resource taxes, not included. Incidence covers half of revenue.

Table 4. Incidence Assumptions Tax Incidence Assumption Comments on operationalization
Personal income Borne by earners (because their take-home pay would rise if there were no tax).
Uses amounts paid as reported in the ENNIV-2000 survey, and grosses these up to get an appropriate total yield.
Value Added Tax Shifted onto consumers. Assumed to be 0% on exempt items – which understates the tax – using 57 expenditure lines. No adjustment was possible for the source of purchases (e.g. supermarket, street market, etc.), which overstates tax, especially on poorer households.
Fuel excise Shifted onto consumers because of horizontal supply curve.
Allocated in proportion to reported household spending on energy. [This is an overstatement, as some effects work via transport, electricity, and individual use, where the incidence pattern is different.]
Alcohol excise Shifted onto consumers because of horizontal supply curve.
Reported spending on alcohol is typically highly understated.
Tobacco excise Shifted onto consumers because of horizontal supply curve.
Allocated in proportion to reported household spending on tobacco; also typically highly understated.
Car excise Shifted onto consumers. Allocated in proportion to car value. Subsidy/spending Incidence Assumption Comments on operationalization
Education Benefits accrue to households whose children are currently enrolled in publicly-supported schools.
Applied average budgetary cost per enrolled student, differentiated by main level of education (primary, secondary, tertiary).
Health Benefits accrue to households whose sick members sought help at a publicly-supported hospital or clinic.
Survey provides information on costs in public and private facilities; subsidy was taken to be the differential between the amount actually paid and an appropriate private-sector norm.
Social subsidies Benefits accrue to households to the full extent of the subsidies.
This overstates the benefits, given that labor supply is not completely inelastic, but probably not by much.

Step 2. Quantify the effects Trace effect of a tax, spending change
on every household in a survey ENNIV 2000. 3,997 households, 19,957
people, LSMS template NB. Assumes equal sharing within
household

Vietnam: Main data source: VHLSS-2006
9,189 households, including 4,298 from 2004 round.
Two visits per household; 93% of interviews in June, Sept or Oct.
Some explicit tax information (e.g. business taxes); otherwise has to be inferred (e.g. VAT, PIT).

Peru: Tax 1: VAT 19% rate. Fairly stable since 1992. Exports zero rated Exemptions include clothing, rice,
milk, fish, vegetables, ed. fees, home consumption, housing
In 2000: 42% of central gov. tax revenue Collected 7.3% of household
expenditure.

Vietnam: Incidence: comments 1 In Vietnam, incidence pattern by
expenditure/cap decile similar to that by income/cap Contrast with Peru
These taxes are progressive overall Heavier, more progressive, than 1998 VAT is generally progressive – mainly due to
home production (1/3 at bottom, 1% at top); not the case in all countries
Excise taxes are progressive – also a bit surprising.

Vietnam: PIT: comments 1 Method: strip out business income
tax and PIT, and apply rules of new tax Revenue: from VND127k to VND21k per
person. New tax highly progressive.
But: excludes foreigners; very small sample size for PIT and for large household enterprises.
Vietnam: Method 1: High-income survey Done by General Dept. of Taxation in
2005, using tax rolls Survey, asking about income, spending 15,500: 3,200 foreign, 7,200 PIT, 5,100

Vietnam: Comparison, old vs. new PIT Based on 2009

▪ Foreigners: down by a quarter▪ Vietnamese: tax payments up
Reconcile with VHLSS data High-income individuals would pay more Not-so-high income individuals would pay less, and not be in the
tax net as much Difficult to merge the two; in progress.
Keep: taxes foreigners, adds equity. Enforcement could be better. Perhaps limit top rate to top CIT. Adjust brackets for inflation (as in US).
Vietnam: Property tax?
VHLSS has limited data on property: Residence; non-agric. real estate Assume tax would not apply to
agricultural property, or to movable property.
1% of capital value; arbitrary

Vietnam: Comments on property tax Highly progressive 1% is steep; 7.8% of expenditure, so
politically infeasible at this level. Cash flow concerns Based on bubble prices? Introduction of tax would reduce base
Excludes corporate ownership

7. Nine Current Issues of Tax Policy Having set out the key features of each main tax, we now turn to an analysis of several current issues of tax policy, one at a time. We are then ready, in the final section, to discuss a number of complete tax reform strategies. Issue 1: How High a VAT?
Given the government’s need for more revenue, it is widely accepted that the VAT rate will need to rise. The issue is: by how much?
A good place to start is with an analysis of an increase in the VAT from 10% to 12%, which is the smallest increase under serious consideration and is generally accepted to be quite feasible. The impact is set out below: overall tax revenue would rise by 3.9%, equivalent to 0.65% of GDP; and the increase in the tax burden would be relatively larger for more affluent households. We have assumed that as the VAT rate rises, people purchase fewer goods that are subject to the VAT; in part this is because they face a budget constraint, so a rise in the VAT rate from 10% to 12% would, if spending is held constant, raise revenue by 17.9% and not by 20%. In addition, faced with a higher VAT rate, buyers would tend to substitute items that are not subject to the VAT. We use a “revenue loss parameter” of 0.8, which means that a 20% increase in the VAT rate would be accompanied by a 16% (i.e. 0.8 times 20%) rise in revenue (and we allow for an additional response for motor fuel and tobacco). Even this may be too low; Agha and Haughton (1996) estimate, based on data from OECD countries, that every percentage point increase in the VAT rate is associated with a 2.7% fall in compliance, which would imply a revenue loss parameter of about 0.7.
An increase in the VAT from 10% to 12% would raise little more than a fifth of the revenue that is considered necessary if Lebanon is to escape from its current vicious cycle of debt. This prompts one to ask what would be the effect of an increase in the VAT rate from 10% to 16%. The result would be a LBP510bn rise in revenue, equivalent to 2% of GDP. Again, the burden would fall slightly more on rich than on poor households, although even the latter would find their real expenditure cut by 2.3%. Here too we have taken into account that a 60% rise in the nominal VAT rate would lead to an increase in revenue of substantially less than this.
An important question is whether the VAT, introduced just over two years ago, is robust enough to withstand a substantial increase in the rate. This is a clear case where “Tax administration is

Lebanonfrom the capacity and evolution of tax administration.
Of the 15,400 registered VAT payers, roughly 1,000 are audited every quarter, almost double the proportion of most other jurisdictions, and a reflection of the newness of the tax. On the other hand the VAT department is well trained and adequately staffed, and could probably make a VAT of 16% work without too much leakage, particularly as three fifths of the revenues are collected on imports.
A broader question is how far one can push a VAT. Agha and Haughton have constructed an interesting graph, reproduced here, that shows that once the VAT rate exceeds about 15%, the pressure to shrink the base becomes very strong. The implication is that the revenue-maximizing point is then reached quite quickly, and appears to be in the region of 7-8% of GDP; all the countries in the sample whose VAT raised more than 7% of GDP are ranged along the frontier in this diagram.. Our simulations, detailed above, show that a VAT of 16% would raise about 7.0% of GDP in revenue, which is as far as one can reasonably expect to go.

Lebanon2. A Revenue-Neutral Reform, Emphasizing Equity An alternative revenue-neutral reform would keep the VAT at 10%, but improve the efficiency of taxes on the income side. The wage and salary tax, and the tax on proprietors’ income, would be unified with a 10% basic rate, rising to 20% on income above LBP60 million; and with a personal tax deduction of 1.5 million. The corporation income tax would rise to 20%, while the capital gains and inheritance taxes would be abolished. A property tax levied at 0.5% of the value of property above LBP120m would replace the current graduated built property tax. Total revenue would rise fractionally, but the tax system would become more progressive, with the tax Gini rising from 0.474 to 0.480. Further details are provided in the table. 3. The Prime Minister’s Proposal of 2003
Although it is no longer actively under consideration, the Prime Minister proposed, in 2003, a radical set of tax changes that would shift the weight of taxation away from income and onto expenditure. Specifically he suggested raising the VAT from 10% to 16% and the corporation income tax from 15% to 20%; at the same time several taxes would be abolished, including those on wages and salaries, built property, and inheritance, as well as some minor excises, and educational fees.
We estimate that the plan would have raised tax revenue by 5.8% in 2003, an increase of LBP263bn. Although the plan would have considerably simplified tax administration, it had two drawbacks. First, it did not raise enough additional revenue to be convincing to the Paris II donors, who wanted (and still want) to see a more substantial effort to achieve fiscal balance, and would not have favored the elimination, even temporarily, of taxes on personal income. Second, the proposal would have fallen most heavily on the poor, who spend on consumption (and so would be hit by the higher VAT) but are less likely to pay taxes on wages or capital income (and so would not benefit from the reduction in those taxes.
