I recently sent a letter requesting an amendment to my 2021-2022 self-assessment tax return. And after the amendment, there is still no tax due for this year. Could you please let me know if it is standard practice to receive a response or confirmation upon receipt of such a request? If so, how long does it typically take to receive a reply?

Between 2021 and 2024, my only wage income was from overseas. The amounts for these three years were £12,388, £13,685, and £8,288 respectively.I have now left my job and retired. My employer was not part of the PAYE system. During these three years, I contributed to Class 3 and have already submitted Self Assessment. Is it acceptable? The Class 3 contributions are higher based on these income. Can I leave thing as they are without making any changes?
