File your UAE Corporate Tax return — with confidence
OneTaxCalculator™ guides you through the entire UAE CIT filing process with a smart questionnaire, automatic routing based on your entity type, and an AI-generated report ready for submission.
Does this sound familiar?
UAE Corporate Tax is new and complex — many SMEs are unsure where to start
Hiring a tax advisor for a straightforward return feels expensive
Uncertainty about which modules apply — SBR, QFZP, exempt income, transfer pricing
Fear of making mistakes on the FTA portal without professional validation
No easy way to self-assess your CIT position before committing to a filing approach
