Form 100. 2018 Personal Income Tax return


The amounts posted as depreciation of tangible fixed assets, intangible assets and real estate investments are deductible expenses, corresponding to the effective depreciation of the different elements due to operation, use, enjoyment or obsolescence.

Depreciation is considered effective when it is the result of applying one of the methods provided for in article 12.1.a of the Corporation Tax Act, which are in short the following:

  1. Linear amortisation according to the repayment tables established in article 12.1.a of the Corporation Tax Act from January 1, 2015.

  2. Constant percentage of the outstanding value.

  3. Method of digits.

  4. Plan formulated by the taxpayer and accepted by the Administration.

  5. Justification of the amount by the taxpayer.

Tangible fixed assets and real estate investments will start to depreciate from their entry into operational conditions and those of intangible fixed assets from the moment they are in a position to produce income.

The assets of tangible fixed assets and real estate investments must be amortised within their useful life period, understanding as such the period in which, according to the method of amortisation adopted, their value must be fully hedged, excluding residual value.

In the case of intangible assets, their useful life will be the period during which it is reasonably expected that income will take place.

The capital elements for which, in tax periods beginning before 1 January 2015, a depreciation coefficient was being applied other than that corresponding to them by applying the new amortisation table provided for in article 12,1 of the Spanish Corporation Tax Act, they will be amortized during the periods that will be subtracted until their useful life is complete, in accordance with the table above, on the net tax value of the existing good at the start of the first tax period starting from 1 January 2015.

The new coefficient will be applicable during the useful life of the new assets acquired in the aforementioned period.
