My question is regarding insurance, can you please tell me how to do it? Our acc year is 1Apr 2020-31 March 2021
Since we follow cash basis should only 5280 be included as it’s payable annually in advance so would be paid in Jan 2021 so within the year. And 5480 would have been paid in Jan 2020 so outside the acc year. So per cash basis only 5280 be included?
