1: REASONS WHY WE RECITE TA'OOZ? (Unlike bismillah, it's not written before any Surah)

Because Allah subhan hu Ta'ala ask us to recite it:

Allah says in Surah An-Nahl: 98

فَإِذَا قَرَأْتَ الْقُرْآنَ فَاسْتَعِذْ بِاللّهِ مِنَ الشَّيْطَانِ الرَّجِيمِ 

“So when you want to recite the Qur'ân, seek refuge with Allâh from Shaitân (Satan), the outcast (the cursed one)”

Shaitan is our enemy

because Shaitan is our enemy, was among Jinn. He disobeyed ALLAH because of jealousy with Man.

Why he is our enemy?

He blames man is responsible for his rejection by Allah.

Allah says in surah Yaa-Seen: 60

أَلَمْ أَعْهَدْ إِلَيْكُمْ يَا بَنِي آدَمَ أَن لَّا تَعْبُدُوا الشَّيْطَانَ إِنَّهُ لَكُمْ عَدُوٌّ مُّبِينٌ

“O Descendants of Adam! Did I not take a covenant from you that you shall not worship the devil? Undoubtedly, he is your open enemy.”

He doesnt want to let us achieve our destiny.

Allah created man n jinn for HIS worship n shaitan doesnt want to  let us to achieve this aim of our life.

so  he make hurdles in way of Allah enemy is always with us, he circulates with blood. Our everlasting home is in akhrat and he never wants us to succeed in getting that destiny.We'll always find shaitan at sirata-mustakim.

Quran is the way towards Allah so specially during learning Quran he makes hurdles

If we want to be safe from the enemy we should take Allah's refuge.

We'll be bothered by the hurdles n whispers of shaitan

So against that we can  take help from Allah.These hurdles are our evil thoughts, ppl fear that they will be called as fundamentalists,  maulve or conservative etc but most of these hurdles are only our thoughts.

Quran is a way towards janant n shatitan will never want us to go in jannah. he is rejected n he challenged that he'll never let  man to come towards ALLAH.

Taooz is our refugee camp against shaitan. 

Shaitan  knows that once we'll learn about Allah's Book Quran, we'll get to build a relation with ALLAH n will surely be out of his reach.Only strong belief in Allah keeps shaitan away from us.

Allah says in Surah An-Nahl: 99

إِنَّهُ ۥ لَيۡسَ لَهُ ۥ سُلۡطَـٰنٌ عَلَى ٱلَّذِينَ ءَامَنُواْ وَعَلَىٰ رَبِّهِمۡ يَتَوَڪَّلُونَ

“Verily! He has no power over those who believe and put their trust only in their Lord (Allâh)”

He doesnt want us to remember Allah

He doesnt want us to build a relation with our creator Allah subhan

Allah says in surat alfurqan :29

لَقَدْ أَضَلَّنِي عَنِ الذِّكْرِ بَعْدَ إِذْ جَاءنِي وَكَانَ الشَّيْطَانُ لِلْإِنسَانِ خَذُولًا

“He led me away from the remembrance after it had come to me. And ever is Satan, to man, a deserter”

Rasul Allah saw said:

“Hadith: (According to Ibne 'Abbas) : "The devil sits clinging to a person's heart. When he remembers Allah, the devil gets lost but when he forgets, the devil puts evil thoughts” (Bukhari)

Shaitan suggests evil to man

Allah describes this in surat Fussilat: 36

 وَإِمَّا يَنزَغَنَّكَ مِنَ الشَّيْطَانِ نَزْغٌ فَاسْتَعِذْ بِاللَّهِ إِنَّهُ هُوَالسَّمِيعُ الْعَلِيمُ 

“And if there comes to you from Satan an evil suggestion, then seek refuge in Allah. Indeed, He is the Hearing, the Knowing.”

We dont want to be the companion of shaitan

Allah subhan says in surat Al Zukhruf:36

وَمَن يَعْشُ عَن ذِكْرِ الرَّحْمَنِ نُقَيِّضْ لَهُ شَيْطَانًا فَهُوَ لَهُ قَرِينٌ

“If anyone withdraws himself from remembrance of (Allah) Most Gracious, We appoint for him an evil one, to be an intimate companion to him”

Another saying of Allah in  al-mujadila: 19

اسْتَحْوَذَ عَلَيْهِمُ الشَّيْطَانُ فَأَنسَاهُمْ ذِكْرَ اللَّهِ أُوْلَئِكَ حِزْبُ الشَّيْطَانِ أَلَا إِنَّ حِزْبَ الشَّيْطَانِ هُمُ الْخَاسِرُونَ

“Satan has overcome them and made them forget the remembrance of Allah. Those are the party of Satan. Unquestionably, the party of Satan - they will be the losers.”

2: IT MAKES A GREAT DIFFERENCE IF WE WILL NOT RECITE IT

• We shall Disobey ALLAH as its Allah's order.
• We shall be easily trapped by shaitan.
• We'll not be able to do good deeds and learn Quran.
• and we'll forget the rememberance of Allah

We donot want to be the party of losers but the succeeded one. May ALLAH take us in HIS refuge from evils of shaitan n make our path easy towards Jannat al firdous ameen. :)

Allah knows the best. :)
