family and private life 10 year route

Hi Gurus,

I need some help on my wifes visa application.

History-
My wife was given 2.5 year leave to remain on family and private life 10 year route in 2020. Then I did FLR FP application in 2022 and she got visa until Aug 2025. Now I am in a process of extension for another FLR FP application.

Q1- Is there a financial requirements ?

As I am supporing her and I am getting my income of year 2023-2024 from dividends, salary and self employment. The accounts were submitted in July 2025. For year 2024-25 the accounts are due in Jan2026 so there is no payslip or any income to show until the accounts are submitted in Jan 2026.

Q2- Providing my self assesment Tax return 2023-24 should be enough?
Q3- Do I need to show my other savings etc ?

In the FLR FP application it ask to upload the payslips which I dont have from the last 6 months which I dont have, what should I do ?

Thanks
