For many foreign residents, moving to Spain is a dream—sun-drenched days, Mediterranean lifestyle, and the unique rhythm of island life in Tenerife. But behind the beauty lies one of the most complex aspects of relocation: understanding and managing the Spanish tax system.
Oxana Ogirenko, better known as Ksenia, is an experienced international tax advisor, accountant, and business management expert. She has built her career around helping foreign residents and entrepreneurs confidently face the often-confusing world of Spanish taxes.
She is the founder of Tenerconsulta Plus S.L., a consultancy headquartered in Tenerife with a branch office in Barcelona. From these two strategic locations, she and her team provide tailored services for both individuals and businesses navigating Spain’s demanding tax and financial environment.
Ksenia was born in Saint Petersburg, where she graduated with honours from Saint Petersburg State University in 1997. Her academic journey also led her to the University of Las Palmas de Gran Canaria, where she earned a degree in taxation, strengthening the foundation for her international career.
She has lived on the island of Tenerife since 2002, making it not only her home but also the base from which she has built a thriving consultancy. Over the years, she has become deeply rooted in the professional community as a member of the Canary Islands Tax Advisors Association, while also mastering Spain’s intricate accounting and tax system. Today, she brings more than 15 years of professional experience to her clients.
In addition to her expertise, Ksenia’s international outlook is reinforced by her languages: she is fluent in Spanish and English for her professional work, and also speaks Norwegian, Danish, and Swedish, enabling her to connect with an even broader range of international clients.
With her combined academic background and hands-on experience, Ksenia offers more than technical knowledge: she provides clarity, context, and confidence. She doesn’t just file paperwork; she makes sure her clients truly understand their tax obligations and opportunities. Whether advising retirees settling into island life, remote workers exploring the benefits of Spanish residency, or international companies opening branches in Barcelona, her goal is the same: to turn complexity into simplicity.
Spain’s tax system can be daunting for newcomers. Between multiple layers of taxation, frequent regulatory changes, and differences in local and national rules, it is easy to feel lost. For foreign residents, the difficulty is doubled: translating not only the language, but also the cultural and bureaucratic nuances that define how the system works.
Add to this the unique reality of living on an island such as Tenerife, where insular regulations sometimes diverge from mainland Spain, and the picture becomes even more complex. Understanding regional differences—such as the Canary Islands’ distinct fiscal regime (IGIC instead of VAT, for example)—requires expert guidance.
What sets Ksenia apart is her ability to contextualise financial advice in the real lives of her clients. She understands that taxes aren’t just numbers—they are decisions that affect families, businesses, and futures. Living and working in Tenerife, she has firsthand knowledge of how island life brings its own opportunities and challenges, and she integrates this perspective into her work.
What stands out most is his ability to read people. Behind the lens, he doesn’t just see a subject—he sees character, emotion, and story. That sensitivity allows him to craft visuals that go beyond aesthetics, touching something deeper.
Not all empires are built under the spotlight. Some are built in silence, brick by brick, stitch by stitch, by people who prefer action to applause.
To speak of Tina Turner is to speak of a hurricane of energy, of a woman who didn’t just sing—she roared her place into the world.
