I'm a self employed writer. I work from home - parents' house. I'm fairly sure my parents house counts as my home. I have no other and I treat it as such. I'm tax resident in the UK. For 3 months I lived in Spain, rented an apartment and worked from home in Spain. Can I claim home office expenses like I would if I rented an apartment in a UK city for 3 months? Just to make clear. I'm not looking to claim travel expenses. This wasn't a research or business trip. I didn't choose Spain because of my writing. I chose it because I simply wanted to live and work there for a few months. I didn't use the space wholly for work. Just like when I've lived in a UK city before. I work in the living room and calculated the amount of time it was an "office".
