I'm self-employed, my income earned on my job last fiscal year was less than my expenses on running my business, but I have other income on my saving. When calculating the income tax, will all the incomes summed up first and then deduct the expenses to calculate the income tax, or just calculate the income tax based on the income from my saving?

Thank you for your reply. If I didn't pass the test to be UK resident, is it true that I don't need to report for the tax and thus I don't need to consider the split year arrangement?

If I move to UK last December and live in a flat throughout the remaining time of the tax year, but I still have the overseas home that I live before I move to UK, and I will live in the overseas home ocassionally later. As I live in there for more than 30 days before I move to UK, can I assume that the above point was not satisfied?
