As we are Muslim Allah anounced award for our each good deeds like jannah for good people but if the non-Muslim is same and doing good deeds like he is helping others he is not telling alie he is good with his family then what is his reward even if he did not believe on Allah and not accept Islam ?
There are different opinions which also depends on different circumstances. One is:
Indeed, those who believed and those who were Jews or Christians or Sabeans—those who believed in Allah and the Last Day and did righteousness—will have their reward with their Lord, and no fear will there be concerning them, nor will they grieve.
This appears to suggest that they will be rewarded for their deeds as long as they believed in God, day of judgement and did good deeds. If they wouldn't grieve and have no fear, this implies they will enter the Jannah (But Imam Ghazali disagrees and suggests that just because they're among those who will grieve doesn't mean they will be among the successful - They will not enter hell but neither will they enter heaven). However your question is about those who do not believe in Allah so it doesn't really apply to them.
There are scholars who maintain that this Ayat applies only till the arrival of Prophet Muhammad (PBUH). After the arrival of Prophet Muhammad, Islam is considered the only way for salvation. That reasoning is usually based on the following:
And whoever desires other than Islam as religion—never will it be accepted from him, and he, in the Hereafter, will be among the losers
“Verily, whosoever sets up partners (in worship) with Allâh, then Allâh has forbidden Paradise to him, and the Fire will be his abode”
“And We shall turn to whatever deeds they (disbelievers, polytheists, sinners) did, and We shall make such deeds as scattered floating particles of dust”
and thanks to uMh:
Indeed, those who disbelieve in Allah and His messengers and wish to discriminate between Allah and His messengers and say, "We believe in some and disbelieve in others," and wish to adopt a way in between. Those are the disbelievers, truly. And We have prepared for the disbelievers a humiliating punishment.
Also a Hadith:
‘Aa’ishah (may Allaah be pleased with her) asked the Prophet (peace and blessings of Allaah be upon him) a question similar to that asked here. She (may Allaah be pleased with her) said: “O Messenger of Allaah, during the Jaahiliyyah Ibn Jud’aan used to uphold the ties of kinship and feed the poor. Will that be of any avail to him?” He said, “No, that will not be of any avail to him, because he never said ‘O Lord, forgive me my sins on the Day of Judgement.’”
Sahih Muslim 214
and again, thanks to UMH:
By Him in Whose hand is the life of Muhammad, he who amongst the community of Jews or Christians hears about me, but does not affirm his belief in that with which I have been sent and dies in this state (of disbelief), he shall be but one of the denizens of Hell-Fire.
Sahih Muslim 70
So overwhelming evidence suggests that if a person was alive at the time or after the arrival of Prophet Muhammad and did not believe in him, that person would be among the people who get punished, not rewarded.
