Tax year 23/24 and 24/25 on my assessment

Hey wondering if some one can shed some light as new to all this, I have done a self assessment and wondering why it says this below Total amount due for 2023-24 Plus First payment on account for 2024-25 Total to be added to Self Assessment account due by 31 January 2025 Second payment on account for 2024-25 will be due by 31 July 2025 Why is it showing I need to pay next years before I’ve even do another assessment :/ I’ve left the figures out which I’m hoping are irrelevant to who knows about this kind of stuff Regards

Hi,

When you submit your Self Assessment tax return, if the balance due is over £1000, and less than 80% of your tax is deducted at source, then payments on account are introduced towards the next tax year's balance. You can see guidance here:

Thank you.

Thank you for replying, This helped me to try to understand it a bit better. It’s not so straight forward to understand, now I know why people get an accountant to do this, but I don’t see the point of doing it as I write everything down on a spread sheet an keep all receipts an logs to back it up Jamie
