The weekly statistical report on daily sales, flash domestic sales, and domestic sales progress for large companies and SMEs provides a detailed snapshot of commercial activity in the Spanish tax system. Published on 1 July 2026, the report aggregates data submitted by large enterprises and small‑ and medium‑sized enterprises, capturing the volume of sales recorded each day, the provisional figures for domestic sales that are released shortly after the close of business, and an interim assessment of sales trends for the current week. The figures are derived from VAT‑registered businesses that file regular tax returns, and they are processed by the Agency to monitor economic activity, detect anomalies, and support the preparation of tax forecasts. The methodology combines information from electronic sales registers with voluntary declarations, ensuring coverage of both the formal and informal segments of the market. The report also includes comparative tables that illustrate how current week sales compare with the same week of the previous year, as well as year‑to‑date accumulations. Analysts use these statistics to assess sectoral health, to calibrate withholding tax estimates, and to evaluate the impact of fiscal policies on consumption. By publishing the data on a weekly basis, the Agency aims to increase transparency and to enable policymakers, investors, and market participants to react promptly to emerging trends.
