Modelo 390 brings the whole year's VAT together in one document: the VAT charged on your issued invoices, the VAT paid on your purchases and expenses, and the result of each quarter. If your Modelo 303 returns are correct, the 390 is little more than a sum; if it does not reconcile, the problem usually sits in an earlier quarter, not in the summary itself.
Some filers are exempt from submitting it if they meet certain conditions, though it is worth checking each year since the exceptions can change. Those who are exempt usually have to provide extra information in the last quarterly return instead.
The typical mistake is fixing a figure directly in the 390 without first correcting the Modelo 303 for the affected quarter. The annual summary does not replace the quarterly return: if a quarter was wrong, you file a supplementary return or request a correction for that period, and the 390 then shows the corrected figures. Another common slip is leaving out transactions that carry no VAT, such as exempt or intra-Community operations, which are also reported here.
The 390 is built from your issued and received invoice registers, and the tax agency cross-checks it against what your clients and suppliers declare. In kontora the summary comes from the same double-entry bookkeeping as your 303 returns, so you see any mismatch before filing.
