3 Concept Explorer 18.1 Classifying an ad valorem sales tax Suppose the price of a bottle of wine is $5,000. If a 60% ad valorem sales tax is imposed, is such tax proportional?

4 Given the 60% ad valorem tax rate, the tax payment for the wine is $5,000 x 60% = $3,000. Suppose the income of Mr. A is $30,000. When he pays this $3,000 sales tax amount, the tax takes up 10% of his income. Suppose the income of Mr. B is $300,000. When he pays this $3,000 sales tax amount, the tax only takes up 1% of his income. The tax takes a falling percentage of income when income is higher. Hence it is regressive but not proportional. Reminder : Currently, there is no interest tax ( 利息稅 ) and capital gain tax ( 資產增值稅 ) in Hong Kong. This means the interest income from banks deposits or bonds, dividends from shares and increased value of real properties are not liable to tax in Hong Kong. Concept Explorer 18.1

5 Theory in Life 18.1 The salaries tax system of Hong Kong Is the Hong Kong salaries tax system progressive or proportional?

6 Theory in Life 18.1 If the (annual) gross income of the income earners in Hong Kong is more than the tax allowances, their taxable income will be taxed by the HKSAR government according to the following schedule: Taxable incomeTax rate First $30,0002% Next $30,0008% Next $30,00014% The remaining20% Table 18.1 Hong Kong salaries tax schedule in 2004 – 2005

7 Since higher taxable income leads to higher tax rate, such salaries tax system is progressive. But if the salaries tax payment of a taxpayer exceeds 16% of his gross income, then the above tax schedule will not be applied. Instead, the taxpayer’s salaries tax payment will be calculated by : Tax payment = Gross income x standard rate ( 標準稅率 ) In the fiscal year 2004 – 2005, the standard rate is 16%. Hence if a person’s gross income is $1 million, his salaries tax payment will be $1m x 16% = $160,000. If his gross income future increases, the tax rate applied is still constant at 16%. Hence the salaries tax system is proportional for higher income earners. Theory in Life 18.1

8 Gross income taxable income allowances 0 Tax rate (%) 16 proportional progressive I1I2 Fig The salaries tax system in Hong Kong Fig shows that if a person’s gross income is less than I1, he does not need to pay salaries tax as his gross income does not exceed tax allowances. If his income is between I1 to I2, he needs to pay salaries tax at the progressive range. If his income is I2 or more, needs to pay salaries tax at the standard rate of 16%, i.e. the proportional range.

9 Concept Explorer 18.2 Comparing direct taxes and indirect taxes What are the advantages and disadvantages of direct taxes over indirect taxes?

10 Concept Explorer 18.2 The advantages of direct over indirect taxes are: Direct taxesIndirect taxes 1. On income distribution As salaries tax and estate duty are progressive, income inequality & wealth gap can be reduced. As indirect taxes are regressive, income inequality & wealth gap will be enlarged. 2. Costs of collecting taxes Since the tax burden cannot be shifted to a third party, the costs of collecting direct taxes can be reduced. Since the tax burden can be shifted to a third party, extra costs of collecting indirect taxes are involved. Table 18.2 The advantages of direct over indirect taxes.

11 Concept Explorer 18.2 The disadvantages of direct over indirect taxes are: Direct taxesIndirect taxes 1. On tax base ( 稅基 ) Salaries and profits tax revenue depend on the salaries and profits earned by the citizens and firms. During recovery or prosperity, salaries and profits tend to be high. These sources of tax revenue will also be high. During recession or depression, salaries and profits earned tend to be low / high, thus these sources of tax revenue will also be low / high. Hence the revenue from direct taxes is relatively unstable because of a narrow tax base. As different kinds of indirect taxes revenue come from different sources (e.g. transaction of goods & services, rental value of apartment, transactions of shares & properties, etc.), the tax revenue from these sources are less affected by a business cycle. Hence the revenue from indirect taxes is relatively stable because of a wide tax base.

12 Concept Explorer 18.2 Direct taxesIndirect taxes 2. Willingness to work and invest Direct taxes extract part of salaries and profits as taxes. This discourages people to work and invest, and reduces working and investment incentives. Indirect taxes do not directly extract part of salaries and profits as taxes. This will not discourage people to work and invest, and will not reduce working and investment incentives. Table 18.3 The disadvantages of direct over indirect taxes. Reminder : Tax base refers to the number of people paying taxes. A wider tax base means more people fall into the tax net; and vice versa.

14 Q18.2 What is the main difference between direct and indirect taxes? For direct tax: the tax burden cannot be shifted to a third party. For Indirect tax, the tax burden can be shifted to a third party. Progress Checkpoint 1

15 Q18.3 The following are some taxes in Hong Kong : Rates Property tax Estate duty Stamp duty For each of the above, classify whether it is : (a) a direct or indirect tax, and (b) a progressive, proportional or regressive tax. Rates : an indirect and regressive tax Property tax : a direct and proportional tax Estate duty : a direct and progressive tax Stamp duty : an indirect and regressive tax Progress Checkpoint 1

16 Progress Checkpoint 1 Q18.4 The following shows the Hong Kong salaries tax schedule in 2004 – 2005 : Taxable incomeTax rate First $30,0002% Next $30,0008% Next $30,00014% The remaining20% Standard rate16% Based on the above table, calculate the salaries tax payment of the following two persons: Annual gross incomeTax allowance David$750,000$100,000 Simon$800,000$100,000

17 Progress Checkpoint 1 For David : Taxable income = $(750,000 – 100,000) = $650,000 Salaries tax payment = $30,000 x 2% + $30,000 x 8% + $30,000 x 14% + $560,000 x 20% = $119,200 Salaries tax payment as a percentage of gross income = $119,200 x 100% = 15.89% $750,000 For Simon : Taxable income = $(800,000 – 100,000) = $700,000 Salaries tax payment = $30,000 x 2% + $30,000 x 8% + $30,000 x 14% + $610,000 x 20% = $129,200 Salaries tax payment as a percentage of gross income = $129,200 x 100% = 16.15% $800,000

18 Since the tax payment exceeds 16% of his annual gross income,he just needs to pay salaries tax at the standard rate only. Salaries tax payment= $800,000 x 16% = $128,000 Progress Checkpoint 1

19 Q18.5 If the government orders every citizen in Hong Kong to pay $100 annually as tax, is such tax progressive, proportional or regressive? Explain. Regressive. It is because the tax amount takes a falling percentage of income as income rises. Progress Checkpoint 1

20 Q18.6 “If the tax payment increases when taxable income increases, then the tax is progressive.” Do you agree? No. For progressive, proportional & regressive tax systems, when taxable income rises, the tax payment can also rise. The difference lie in how the (average) tax rate changes when taxable income rises. Progress Checkpoint 1

21 Q18.7 Suppose Mr. Chan earns HK$200,000 from his investment in Australia. Does he need to pay tax to the HK SAR government? Which principle of taxation is applied? Explain. No. This is because the source of receipts is not the Hong Kong economy. This is the source principle of taxation. Progress Checkpoint 2

22 Theory in Life 18.2 The effects of a change in progressivity on income distribution The following shows the Hong Kong salaries tax system in the fiscal years 1992 – 93 & 2002 – 03: 1992 – – 03 Basic allowance$39,000Basic allowance$108,000 Taxable incomeTax rateTaxable incomeTax rate First $20,0002%First $35,0002% Next $20,0009%Next $35,0007% Next $20,00017%Next $35,00012% Remainder25%Remainder17% Standard rate15%Standard rate15% What are the changes of the salaries tax system? How do these changes affect (a)income distribution between the rich and the poor, (b) the general price level, (c) labour supply and (d) gross domestic product of the economy?

23 These two salaries tax systems can be represented by the following diagram : Theory in Life 18.2 Fig The Hong Kong salaries tax system in 1992 – 93 and 2002 – 03.

24 Theory in Life 18.2 The changes of the salaries tax system shown above are: The changes implied The changes seen in the table The changes seen in the diagram 1.An increase in basic allowance. From $39,000 to $108,000 Point A moves to point B 2.An increase in tax band ( 稅階 ) (i.e. the range of taxable income that a particular tax rate applies) From $20,000 to $35,000 The curve showing the new salaries tax system is flatter. 3.A decrease in progressivity ( 累進程度 ) (i.e. how progressive the salaries tax system is). From 2%, 9%, 17% & 25% to 2%,7%, 12% & 17%. However, for both salaries tax systems, the standard rate is kept constant at 15%.

25 (a) The effect on income distribution As there is an increase in basic allowance, some tax payers whose annual gross income is higher than the original basic allowance but lower than the new one can escape from the tax net. These people usually belong to the low income group. As there is a decrease in progressivity, some tax payers can pay taxes at tax bands with lower tax rates. Hence they pay less taxes. These people usually belong to the low and middle income groups. As there is no change in standard rate, some tax payers pay the same amount of taxes. These people usually belong to the high income group. As the low and middle income group get benefits from the changes but not for the high income group, the income distribution is more evenly distributed (i.e. the wealth gap between the rich and the poor is narrower). Theory in Life 18.2

26 (b)The effect on general price level Since the low and middle income groups have higher disposable income, their demand for goods and services increase. There will be an upward pressure on the general price level. (c)The effect on labour supply With a decrease in tax rates, the net income from work increases. This increases the working incentive of the low and middle income groups. Their labour supply will increase. (d)The effect on gross domestic product As the demand for goods and services increase, GDP tends to increase and unemployment rate decrease. There is an expansionary effect on the economy. Theory in Life 18.2

27 Concept Explorer 18.3 Taxes and inflation Suppose a government raises taxes in an economy. Is this inflationary or deflationary? Is this expansionary or contractionary? If the government raises direct taxes (e.g. raising the taxes rates for salaries tax, profits tax, etc.), the disposable income of people will decrease. If the government raises indirect taxes (e.g. sales tax, gasoline tax, hotel accommodation tax, rates), the supply of these goods and services will decrease. The demand for goods and services will decrease. As the tax burden can be shifted to consumers, the general price level tends to increase, i.e. it is inflationary. As aggregate expenditure decreases, the general price level also decreases, i.e. it is deflationary.

Thus GDP will decrease and unemployment rate will increase, i.e. both are contractionary. Concept Explorer 18.3

29 Progress Checkpoint 3 Q18.8 If the government reduces the salaries and profits tax rates, will the total tax revenue from these two sources necessarily fall? Explain. No. When profit and salaries tax rates are reduced, this tends to lower salaries and profits tax revenue. However, with a fall in these rates, people tend to work more and investors invest more. Thus their taxable income and profits will rise. This tends to raise salaries and profits tax revenue. If the effect of a rise in taxable income and profits on tax revenue is greater than that of a fall in tax rates, then the tax revenue will rise.

30 Progress Checkpoint 4 Q18.9 Based on fig. 18.4, on which service does the HKSAR government spend most money? How will this affect the potential GDP of Hong Kong? Explain. Education. This will raise the potential GDP of Hong Kong, because labour will be more productive after receiving education. Fig. 18.4

31 Q18.10 Explain how it is possible for the size of the public sector to increase, despite a fall in the amount of public sector expenditure. The size of the public sector is the ratio of public sector expenditure to GDP. If the fall in GDP is greater than the fall in public sector expenditure, then the size of the public sector may rise. Progress Checkpoint 4

32 Q18.11 Suppose the estimated expenditure and revenue of a fiscal year are $100 and $80 respectively. What kind of budget is this? Deficit budget, because the estimated expenditure is greater than the estimated revenue. Progress Checkpoint 4
