Praise be to Allaah.
The ruling on taxes has
been discussed previously. The basic principle is that taxes are not
allowed, because they are a haraam maks. See the answer to question
no. 39461.
There is nothing wrong with
avoiding them by doing something that does not cause one more harm, even if
that requires paying some money.
Ibn Abi Shaybah narrated in
his Musannaf (5/233) from al-Qaasim ibn ‘Abd al-Rahmaan that when Ibn
Mas’ood came to Abyssinia, he was arrested for some reason, and he gave them
two dinars so that they would let him go.
Taqiy al-Deen al-Subki (may
Allaah have mercy on him) said: What is meant by the bribe that we mentioned
is what is given in order to deny a right or attain something wrongfully. If
it is given in order to get a judgement concerning one's rights, then the
prohibition applies to the one who takes it. As for the one who will not be
able to get his rights without giving it, it is permissible (for him to give
it), but if he is able to get his rights without it, then it is not
permissible. The same applies to what is given for governorships and
positions, it is haraam for the taker in all cases, and in the case of the
giver, it depends on what we have referred to above. End quote from
Fataawa al-Subki (1/204).
Based on that, there is
nothing wrong with you dealing with that office, whether they deal with the
tax department or not, so long as you cannot find any way to avoid or reduce
your taxes apart from that.
