Hello everyone. A bit of background info. I'm a US citizen from Texas (no state taxes) and I've been living in Spain since 2014 as an active duty member but retired last year in Feb 2019. I applied for a Spanish (non-lucrative) visa shortly after I retired and travelled back to the US several times but no longer than 183 days to visit family and apply for the Spanish visa. I purchased a Spanish property in March of 2018 before I retired while I was living in Spain (I had already full intentions to retire in Spain) and am now getting to the point where I must officially claim myself as a Spanish resident and (I suppose) claim this property and myself in both the US and Spain for worldwide tax purposes. Since after filing my taxes in 2019 I'm now considered a Spanish resident (living in Spain for over 183 days) on my second visa (since my first visa expired June 2020). The only "income" I receive is from my retirement pay which is sufficient enough to financially support myself and meet the requirements for a Spanish visa while living overseas.
My confusion is what forms do I have to file (both US and Spanish) in the upcoming 2021 filing year and what all should I expect to be taxed, property, retirement pay, Spanish community/region taxes, etc. I also read I might be eligible for tax exemptions and/or reimbursement for taxes I'll have paid to the Spanish tax system after I file my taxes in 2021.
Any information would be greatly appreciated.
Thank you
