How and where do I specify that I expect my rental income to be "Please tick this box if the property income ceased in 2022-23 and you do not expect to receive such income in 2023-24" This doesn't apply as the income has not ceased, but it's reduced by half, in 2023-24 compared to 2022-23. Can I reduce my Tax due and add details in this field? "You can claim to reduce the payments on account. You should do this if your profits or income are not likely to be the same as the amounts shown in 2022-23. If you wish to claim to reduce your payments on account, please tick this box"
