Sending SA109

I have just moved to Spain and am now registered here for tax and social security purposes, and have residency. I have just completed a tax return to HMRC for the year 2022-2023. As expected, I have to pay partial amounts for the following years' tax. As I am now resident in Spain (and will shortly be sending the SA109 Form), will I get the partial amounts reimbursed? I believe I have to send Form SA109 by post, is that correct? Many thanks in advance for your answer.

Hi

If you expect (having relocated to Spain) to receive reduced taxable-in-the-UK income in 2023-24, you can apply to reduce your self Assessment payments on account using the form linked below.

Any UK tax overpaid in 2023-24 will be repaid when you submit your 2024 tax return, guidance can be found here -

Self Assessment: claim to reduce payments on account (SA303)                                                      

As regards your 2023 form SA109, you should indeed send it by post.  

Thank you.           

Thank you for your answer. Mostly it is clear, but as far as submitting a 2023-24 tax return is concerned: do I need to? I will be paying tax and social security in Spain as of April 2023. Thanks again in advance for your answer. Best regards

Hi Michael Boone,

It depends on what income you still have in the UK.
Please see guidance here:

Thank you.
