I get heartily sick of the ex-pats who don't do tax returns here - they're defrauding Spain and they're also defrauding me.
Personally, I think you'd get away with not doing the non-resident return for 2016, but if it's not going to cost you much, then do it for peace of mind.
To be as concise as possible:
If you're resident here, irrespective of whether or not you've got a residencia certificate, you are legally obliged to pay tax here on your worldwide income, with some exceptions.
The principal exception is that a UK pension in relation to employment by the state is taxed in the UK. However, it is still declared here and can affect the rate at which tax on non-exempt income is calculated.
Tax paid in the UK can be offset against tax due here. You won't necessarily get 100% of UK tax offset against Spanish tax - it depends on your level of income.
Once you've submitted a tax return here, you can do the necessary to get out of the UK Inland Revenue system (apart from the military pension). You'll receive a notice of coding, but this will be NT - no tax. I'll be posting a 'how to' on this in due course. At the time, I was quite chuffed at giving the Inland Revenue the elbow.
With reference to your comment about 'complicated', doing the actual tax return isn't complicated (in my opinion). Working out all the taxable amounts you received in a calendar year, then finding and applying the exchange rate for amounts received in sterling, can obviously take you a bit of time.
For example, this April I'd got all my figures ready. I then spent five minutes getting a number from Hacienda which allowed me to access my tax return. It took about fifteen minutes to do the return itself.- once I'd understood the new online system.
What is complicated is how the calculations are done - horrendously complicated, and it took me a long time to get an understanding of this. However, Hacienda's computer does all the calculations, and instantly gives you a bottom line result.
I've already got several more tax topics to post, once I've finished polishing them. If I remember, I'll add a new one about how the actual calculation is done.
