Submisson of Self Assessment Tax Return via HMRC Online Service - Only showing 95% complete

Hi HMRC, I am using HMRC Online Service to submit Self Assessment Tax Return for 2023/2024. When I entered all relevant parts for Tax Return and checked no parts are missing out, but there still shows that the tax return is "90% complete" . May I ask if I submit the tax return, will it turn to "100% complete" and so I can print out the official online Self Assessment Tax Return for my record / reference. Or, perhaps there is something missed in my Tax Return, and I need to fill it up and make it 100% complete before submission of tax return. Please kindly advise/confirm. Also, once the Self Assessment Tax Return has been submitted to HMRC, if I have something to add/amend for the Tax Return, could I resubmit (amend) the tax return to replace the previous version of Tax Return via HMRC online service? Or, I need to write to HMRC about any change/addition required to update the already submitted Tax Return? In my knowledge, if I use a third party commercial software to submit the Tax Return, I am allowed to resubmit the updated Tax Return to supersede the previously submitted one. I am looking forward to receiving your expert advice. Thank you in advance.

Hi,

If anything is missing from your return, you should see advisory messages detailing which parts of the return still need completing. If you do not see any advisory messages, our system will

allow you to submit your return, confirming it fully complete. After your return is submitted, you can reaccess your return wherever you filed it, and amend and update as you require.

Thank you.

Good afternoon HMRC, Thank you for your reply. I have submitted the tax return with 100% complete and I am able to view SA302 full calculation online now. But, I cannot find any details about capital gain/loss that I reported in SA108 (Capital Gains Tax Summary) in this SA302 summary sheet. I provided computation sheets for reporting of small account of capital gain and asking for NVC in the tax return. In my understanding, the income tax and capital gain tax are separate to be calculated and paid. SA302 is just for income tax and payment details. How about capital gain tax? What notice/letter will I be given for paying capital gain tax if I need to? Where can I find it? For this tax year, I reported a small account of capital gain and asked for NVC (= capital loss) in the tax return. How can I know if HMRC accepts/approves my claim of NVC to be allowable capital losses which could be used later to offset the capitla gains in the future years. Regarding the above concerns, I am looking forward to receiving your expert advice. Thank you in advance.
