Otis Tax is a UK-based platform that helps individuals with tax file returns, targeting those whose affairs aren't complicated and need to file a return due to income from self-employment, investments, or rental properties. The app collects user information on their income details during the tax year, analyzes figures, and provides an estimate of what they would owe by tax deadline time. Otis Tax works with the national tax office's API to file tax returns through its website, guiding users through a simplified process. Founder Ozzy Drakes built his app on Bubble, a no-code platform that provided more creative control than traditional coding methods, allowing him to bring his idea to life without prior coding experience. With over 400,000 users currently building businesses on the platform, Bubble is a leader in the no-code movement and supports entrepreneurs like Ozzy Drakes who want to create technology without extensive technical knowledge.
