Self employed tax for spouse visa

Hi
I have a quick question regarding tax for self employment. Do I have to show that I have paid the full tax amount that is due or can I show payments towards it? HMRC gives sole traders until 31 January 2020 to pay off their tax but I dont know if the Home Office will accept that

thanks in advance.

Usually there are vast amount of documents needed for self employment. You can also attach all those documents showing that you are in agreement with HMRC and paying tax.
