Fiscal policy is one of the most important tools for
eliminating inequality in developed countries;
however, the tax system in the United States and
many other developed countries has become less
progressive over the past 50 years. The search for a
fair taxation system is going on in a three-
dimensional system.
Vertical equity in taxation should take a
progressive form to equalize income, horizontal
equity in taxation implies that people with the same
income level should be taxed the same regardless of
their source of income. Vertical and horizontal
taxation does not involve redistribution, but
adherence to these two principles should at least
ensure that taxation does not exacerbate existing
inequalities. With the development of globalization, a
third dimension has been added – the ability of a
country to ensure an independent tax policy and tax
equality between different countries.
The basic model of tax competition shows that
capital openness leads to tax cuts, especially taxes on
capital (Wulfgramm, 2016) When investors are free
to choose a country to invest in, they choose the
jurisdiction with the lowest tax level, therefore,
governments reduce tax rates one after another to
attract capital from abroad. The basic model of tax
competition has implications for all three principles
of fairness and therefore also indirectly for ensuring
equality in society.
First, if capital gains are taxed less, then the tax
system becomes less progressive, implying that the
rich pay less. In addition, in the face of growing
budget expenditures, governments are forced to look
for alternative sources of revenue, such as taxes on
the purchase of non-essential items or wage taxes. As
a result, the population with lower incomes bears a
larger share of the tax burden. The tax system
becomes potentially regressive, therefore, in the
models of tax competition, the principle of vertical
equality of taxation remains unfulfilled.
Second, tax competition affects horizontal equity.
The same income from different sources – one from
capital, the other from work – is taxed differently.
Third, countries can no longer set their tax
policies independently, thus international equality is
violated. Taken together, tax competition potentially
violates all three principles of equality and, at least in
the case of horizontal and vertical equality, limits the
balancing of the tax system. While all governments
are limited in their choice of tax policy instruments,
income redistribution does not occur equally between
countries; the risks are not the same (Arkadeva,
2019). Asymmetric tax competition models show that
the opportunities for competition vary with the size of
the country. Small countries have a fundamental
advantage, and large countries lose out in tax
competition. If the country is small enough, then the
additional income received from capital inflows from
other countries by increasing the tax base will cover
the shortfall in income from tax cuts on domestic
capital because of the tax rate cut. These capital flows
affect the distribution of income among countries.
The average OECD income tax rate has been cut
by about half from 43% to 25%, and the personal
income tax rate has been reduced from 58% to 40%
(Wulfgramm, 2016), reflecting tax competition for
capital and highly skilled professionals. At the same
time, taxes on low-mobile tax bases – value added tax
and property tax – were increased. To correct the
existing situation and international equalization of
taxation, a working group has been created within the
OECD to develop recommendations to counter the
understatement of the tax base and the withdrawal of
profits. Within the framework of the working group,
negotiations are underway to establish a global
minimum income tax of at least 15%. Thus, it is
envisaged to form an international tax system that
meets the principles of stable development of states
and the establishment of justice. The US Treasury
notes the need for international cooperation in this
direction and the devastating effect of the "race to the
bottom of corporate tax", which undermines the
ability of states to collect taxes necessary for
infrastructure investment, innovation stimulation and
sustainable growth.
One of the negative aspects of the Russian tax
system is its focus on indirect taxes, which are the
easiest to administer. About 70% of tax revenues to
the federal budget of the Russian Federation today are
indirect revenues in the form of value added tax
(VAT), excise taxes and customs duties. If in
developed countries, for the purpose of fair taxation,
budget revenues are formed from taxes on property,
profit, land and capital, then in Russia the main bases
of taxation are consumer spending and labor. Indirect
taxes are included in the prices of goods sold, as well
as in tariffs for services and works. They act as price-
forming elements, causing, in turn, a decrease in
consumption, primarily of the poorest part of the
population. The richer the consumer, the smaller the
share of his income he pays to the consolidated
budget of the Russian Federation. Taking into
account the flat scale of personal income tax, the tax
system of the Russian Federation takes a regressive
form and contributes to the strengthening of social
inequality in society and the increase in poverty in the
country.
