Salam

Please find above scans of the supplication to be recited thrice at the end of the hijri year, taken from Shaykh Abd al-Hamid Quds from Mecca’s work Kanz al Najah.

A quick translation is as follows:

In the name of Allah, Most Merciful, Most Kind
Salutations and blessings of Allah Most High be upon our Master Muhammad, his family and companions.
O Allah, those actions that I have performed in the past year which You forbade me from but I did not repent from and resulted in You being displeased, likewise that which I forgot to perform but You did not forget. You also gave me respite despite Your power to punish me and invited me to repentance after my transgressing against You.
O Allah, I seek Your forgiveness from this so please forgive me.
O Allah, any action which I performed which pleased You and for which You promised a reward and forgiveness, then please accept it from me and do not cut off my hopes in You, O Generous One, O Most Merciful.
Salutations and blessings of Allah Most High be upon our Master Muhammad, his family and companions.

To be repeated thrice. This is not from a Prophetic hadith but a general prayer which some Sunni scholars have found favourable.
