Should he submit a false report about his travelling expenses in order to pay off his taxes?
Question

                The company I work for gives me an amount of money to spend on foods and transportation when I travel to another country to complete an assignment. Is it permissible for me to take this money in order to compensate for the tax they take from my salary, and use it for personal matters? Thus I will give them a false report about the traveling expenses. I read on this website that it is haram to take taxes. May Allah reward you!.
Praise be to Allah.Firstly: 
What is required of the 
    Muslim is to be honest and trustworthy, so he should not tell lies or cheat, 
    because of the sin and bad consequences involved in lying and cheating. 
Allaah says (interpretation 
    of the meaning): 
“O you who believe! Fear 
    Allaah, and be with those who are true (in words and deeds)”
[al-Tawbah 9:119] 
“O you who believe! 
    Betray not Allaah and His Messenger, nor betray knowingly your Amaanaat 
    (things entrusted to you, and all the duties which Allaah has ordained for 
    you)”
[al-Anfaal 8:29] 
“Verily, Allaah commands 
    that you should render back the trusts to those, to whom they are due”
[al-Nisa’ 4:58]
And the Prophet  (peace 
    and blessings of Allaah be upon him) said: “I enjoin you to be truthful, for 
    truthfulness leads to righteousness and righteousness leads to Paradise. A 
    man may continue to tell the truth and endeavour to be truthful until he is 
    recorded with Allaah as a speaker of truth. And beware of lying, for lying 
    leads to wickedness and wickedness leads to Hell. A man may continue to tell 
    lies and endeavour to tell lies, until he is recorded with Allaah as a 
    liar.” Narrated by al-Bukhaari(6094) and Muslim (2607).  
And he  (peace and 
    blessings of Allaah be upon him) said: “The signs of the hypocrite are 
    three: when he speaks he lies, when he makes a promise he breaks it, and 
    when he is entrusted with something he betrays that trust.” Narrated by 
    al-Bukhaari (33) and Muslim (59). 
Secondly: 
If the company gives you 
    some money to use when travelling, and asks you to report your expenses, 
    then it is not permissible for you to lie when writing this report, whether 
    you take the money to pay off taxes or anything else. 
That is because the sin of 
    haraam taxes is only borne by the one who collects them and imposes them; 
    the company has nothing to do with that, and it is not permissible to 
    transgress against its wealth, because it is not permissible to take the 
    wealth of a Muslim unless he gives it willingly. This is in addition to the 
    fact that this action involves lying, so in this case it is a combination of 
    consuming wealth unlawfully, lying and treachery – all of which are haraam. 
If you can come to an 
    agreement with the company that you will take some money and have the right 
    to dispose of it as you wish, then this wealth will be your property, and 
    you can pay off taxes with it or use it for food and transportation. 
And Allaah knows best.
