mechanisms  by  which  taxes  can  affect  economic 
growth.  First,  taxes  can  inhibit  investment  rate 
through  such  taxes  as  corporate  and  personal 
income,  capital gain  taxes. Second,  taxes  can slow 
down  growth  in  labor  supply  by  disposing  labor 
leisure choice in favor of leisure. Third, tax policy 
can affect on research and development expenditure. 
Fourth, taxes can lead to a flow of resources to other 
sectors  that  may  have  lower  productivity.  Finally, 
high  taxes  on  labor supply can distort  the  efficient 
use of human capital high tax burdens even though 
they have high social productivity.  
Moreover, the improvement of tax system (Tax 
Policies) is usually depending on the quality of the 
existing  investments  and  their  size  in  the  state. 
Financial  investments  are  considered  as  the  main 
key  to  support  the  needs  and  demands  of 
government,  and  also  it  is  an  important  tool  that 
used  to  measure  the  economic  conditions  and  the 
growth rates in the state. In this context,  the  study 
has focused on creating a good relationship between 
tax policymakers and financial investments owners. 
Therefore, the relationship in this context means the 
ongoing  process  of  identifying,  establishing, 
maintaining, and enhancing successful relations with 
different  investments and  other  parties. So  that the 
purposes  of  all  parties  (Tax  systems  and 
investments) involved are met, and this is done by a 
mutual giving and fulfillment of promises. Also, this 
relationship is considered as a social relationship in 
order  to  accomplish  the  purpose  of  meeting  the 
interests  of  both  parties,  and  ensure  that  mutual 
needs  are  met  during  social  interactions  between 
these parties. Furthermore, this relationship based on 
communication  between  Tax  policies  setters  and 
investors  (the  owners  of  financial  investments),  in 
which this communication is considered as any act 
by which one party gives to or receives from another 
party  information  about  the  mutual  needs,  desires, 
perception,  knowledge  or  affective  states. 
Communication is defined as the process of passing 
important  information  and  understanding  from  one 
party to another, it is essentially a bridge of meaning 
between taxes and investments. 
Tax is a major sources of government revenue all 
over  the  world.  Government  use  tax  proceeds  to 
render their traditional functions, such as provisions 
of  public  goods,  maintenance  of  law  and  order, 
defense  against  external  aggression,  regulation  of 
trade  and  business  to  ensure  social  and  economic 
maintenance.  Musgrave and Musgrave (2004) stated 
that economic effects of tax include micro effects on 
the  distribution  of  income  and  efficiency  of 
resources use as well as macro effect on the level of 
capacity output, employment, prices and growth. 
Furthermore, to establish the role of Palestinian 
taxes policies and meet the purpose of its existence, 
the  country  should  collaborate  with  investors  in 
order to achieve the interests of state’s economy, and 
achieve  the  internal,  and  external  stability  (Jihad, 
Ghasawna.1999). In addition to reinforcing the main 
concept  of  financial  investment  and  its  role  in  the 
state, the policymakers should confirm the definition 
of  tax  fairness  which  is  the  idea  most  people 
gravitate  towards  when  thinking  about  good  tax 
principles, but the emphasis placed on this issue is 
often  so  great  it  appears  fairness  is  the  only  tax 
concept  that  matters.  Of  all  the  principles  of  good 
tax policy, fairness is the most challenging to put in 
place  since  it  means  different  things  to  different 
people.  Therefore,  if  there  is  tax  fairness  in  the 
issued  policies,  then  this  will  lead  to  upgrade  the 
quality  of  existing  investments,  and  will 
dramatically  improve  tax  system  to  be  such  a  tool 
that all different financial investments would depend 
on.  
1.1  Statement of  The Problems   
In  developing  countries,  the  government  has  to 
control the development and the growth of economy 
or  some  economies  through  setting  policies, 
procedures,  and  legal  instructions.  In  addition, 
government sometimes manage and coordinate some 
investments because private initiative and capital are 
limited.  Tax  policy  is  considered  as  such  an 
important  tool  that  is  used  by  government,  and  it 
means the choice by a government as to what taxes 
to levy, in what amounts and on whom, and it could 
be  the  use  of  government  spending  and  revenue 
collection  to  influence  economy.  Therefore,  tax 
policy is usually used to promote economic growth 
and  stability,  and  promote  social  policy  programs 
with  economic  effects.  Taxation  is  concerned  with 
clarifying  the  main  regulations,  laws  and  policies 
that belong to the followed and the implemented tax 
system,  and  it  exists  in  public  economics. 
Governments  at  all  levels  (national,  regional  and 
local) need to raise revenue from a variety of sources 
to finance public-sector expenditures.  In economics, 
taxes fall on whomever pays the burden of the tax, 
whether  this  is  the  entity  being  taxed,  like  a 
business,  or  the  end  consumers  of  the  business’s 
good. 
According  to  the  classical  economist  the  only 
objective  of  taxation  was  to  raise  government 
revenue. But with the change in circumstances and
