Ivalia helps self-employed professionals in Spain (autónomos) know exactly how much of the money they earn belongs to the tax office. Log your invoices and expenses, or just snap a photo of a receipt: AI reads the date, amounts, VAT rates and category for you. Ivalia calculates your quarterly VAT (Modelo 303) and income tax prepayment (Modelo 130) in real time, including withholdings, previous payments, VAT carry-forward and the rules on which VAT is actually deductible. A savings jar shows how much you have already set aside, deadline alerts keep you on time, and a one-click export gives your accountant everything they need. Built for freelancers who already have an accountant and simply want to avoid surprises. Data is stored in the EU.
