PERSONAL INCOMES FROM ABROAD ARE TAXABLE?

Hola! Can someone know , if Personal Incomes from Abroad MUST DECLARED TO THE CANARY AUTHORITY? And are these incomes from abroad taxable from the Canary Islands?
Thanks a lot.

If you reside in Spain which includes the Canary Islands for 183 days in a year, then you are deemed to be a fiscal resident and you are legally obliged to submit a tax return, declaring your world wide income, which then will be subject to taxation.
