The objective of the Annual Tax Collection Report is to provide information on the level and annual evolution of tax revenues managed by the Tax Agency (AEAT) on behalf of the State and the Autonomous Communities. and the CC.LL. of the Common Tax Regime Territory.

The behavior of tax series is not always easy to understand. Its strong variations contrast with the more parsimonious evolution shown by synthesis variables such as GDP or consumption. There are, however, reasons for these discrepancies; Regulatory changes, changes in tax management or the differential impact that economic developments have on the different tax bases are some of them.

For this reason, and in order to properly understand the behavior of collection and its relationship with economic flows, the Annual Tax Collection Report uses an analysis method in which not only tax revenues are analyzed in terms of cash, but these are also linked to the accrued taxes obtained by aggregating the declarations and these, in turn, with the effective rates and the bases declared by the taxpayers . Thus, the explanation scheme for each tax figure has three levels:

1. Analysis of the evolution of the tax base and the average effective rate, level in which the basic source of information is the annual statistics available on the AEAT website.
2. Analysis of the evolution of taxes accrued, prepared from the periodic self-assessment declarations submitted by taxpayers in compliance with their tax obligations.
3. Analysis of cash collection, detailing the elements that may have influenced a different behavior of income with respect to the obligations generated.

The scheme used tries to cover the entire tax payment process: from the time the taxable event that generates the obligation for the taxpayer occurs until the tax is finally settled and paid. It should be noted that the information on tax bases and taxes accrued for the last two years is provisional.

This method of analysis is possible thanks to the information system available to the Tax Agency, which allows the preparation of annual and quarterly aggregate series of tax bases, taxes accrued, effective rates and cash collections for each tax, all constructed from the microdata provided by taxpayers. This aggregated information can be found on the Tax Agency's website ( www.agenciatributaria.es ).

Furthermore, this same conceptual structure is what supports the budgetary forecast of tax revenues. Its estimate is made taking as a reference the economic scenario predicted for the following year. The growth of the tax bases is adjusted to fit the evolution profiles projected by the scenario. Based on the tax bases and assumptions about the behavior of the effective rates, the accrued taxes are obtained which, when applied to the period of income, give rise to the expected cash collection.

This year's report maintains the structure introduced last year, with a brief text containing the main facts that characterised the evolution of revenues in 2018 and with references to the tables via hyperlinks to an external file containing the data series since 1995. In addition to this table file, two more files are made available to users, one with information on income by Delegations since 2007 and another with the series of rights recognized since 2004. In addition, as is usual in monthly reports, another file is available with the main regulatory developments and the series of legal rates for the different taxes.
