Comparative Analysis of Personal Income Taxation
Rodica Pripoaie1
Abstract: This paper presents a comparative analysis of personal income taxation in different countries. This
is an important component of fiscal policy and directly influences the budget revenues. Over time there have
been several taxation systems, and today they differ from state to state. The statistics contain detailed
information on income ta x on individuals and their income, including gender, age, income and source of
income. This work shows how the income distribution of individual taxpayers has changed over time, as well
as the differences and similarities of personal income taxation in the different countries.

1. Introduction
All people pay taxes, regardless of nationality, sex or religion, so taxation is part of our lives, of all.
Employees pay from wage in addition to personal income tax and a series of social contributions that,
although not of a fiscal nature, are payment obligations that affect net income and which have the
highest percentage of taxes and fees paid.
Worldwide, there is a trend towards fiscal harmonization, but taxes differ greatly from one country to
another, and even within the EU Member States. Thus, the rate of taxation differs greatly depending
on the degree of development of the country concerned, in the sense that it is lower in developing
countries and higher in developed ones.
The income tax on individuals has a very wide scope and differs greatly in terms of tax rates that can
be proportional or progressive. This is a direct tax, paid and directly supported by the individual,
which makes it the basic element of any fiscal system, especially if it is also considered that it
contributes, on average, by about 25-30% to the formation of tax revenues of a country.
The European Union has no role to establish taxes. The rate of tax is decided by the governments of
the Member States. The EU’s role is to ensure that national taxes are in accord with EU policies and
do not discriminate individuals.

2.1. The Organization for Economic Co-operation and Developme nt (OECD) Taxing Wages
The tax wedge is defined by as “tСe combined
central and sub-central government income tax plus employee and employer social security
contribution taxes, as a percentage of labor costs defined as gross wage earnings plus employer social
security contributions. The tax wedge includes cash transfers.”
The all-in tax rate is calculated by as: “tСe
combined central and sub-central government income tax plus employee social security contribution,
as a percentage of gross wage earnТngs.”
Personal average tax rate (or “taб burden”) is the term defined by
policy/tax-database.htm used when personal income tax and emploвees’ social security contribution
are expressed as a percentage of gross wage earnings.
2.2. Evolut ion of Personal Income Tax Rates and Thresholds in OECD Countries during the
Period 2000-2017
Taxing Wages 2018 shows that the “net personal average tax rate” income tax and social security
contributions paid by employees, minus any family benefits received, as a share of gross wages was
25.5% across the OECD. This OECD-wide average rate, calculated for a single person with no
children earning an average wa ge, has remained stable in recent years, but it covers country averages
that range from below 15% in Chile, Korea and Mexico to over 35% in Belgium, Denmark and
Germany. (
