How the DGT's position has evolved
Current position
The offsetting of negative balances in the savings tax base is governed by the integration of capital gains and losses pursuant to Article 49 of the LIRPF (Personal Income Tax Law). In the field of IVA (Value Added Tax), the right to deduction and offsetting is optional, requires supporting documentation such as the original invoice, and is subject to a four-year expiration period. Capital losses must be attributed to the tax period in which the change in assets occurs.
The DGT's position is stable regarding the mechanics of offsetting balances in the savings base, consistently applying Article 49 of the LIRPF. No doctrinal changes are observed, but rather a repeated application of the rules for integrating capital gains and losses in different scenarios, such as the transfer of housing, securities, or the dissolution of companies. Regarding IVA, the taxpayer's option and the need to comply with formal requirements are maintained.
