Hi there KJB and welcome aboard Filipino UK

Glad you managed to find a forum thread that helps you.
Do take the time to review carefully any links within that thread and also be sure to carefully review the Self-Employed section of the UKVI Financial Requirement.

As you have discovered, the specific rules for those who are self-employed can be a little complex and confusing.

You'll find there are two categories:-
- Category F - you are in self-employment at the date of application and using income from the last full financial year to meet the financial requirement.

- Category G - you are in self-employment at the date of application and choose to use an average of the income received in the last 2 full financial years to meet the financial requirement.

Taxable income for Self-Employed is revenue less business expenses.
Do be aware that if your business accounts show that you are being taxed on an amount less than £18600 then the application will fall for refusal. Period.

I guess based on the information you've shared that you do not have your own regular accountant ?

Good luck
