The effective amount of what was paid abroad due to a personal tax that affects the assets counted in the Tax.

The result of applying the average effective tax rate of Tax to the part of the taxable base taxed abroad.
The average effective tax rate (TMG) is the result of multiplying by 100 the quotient of dividing the full amount of the Tax by the taxable base. The average effective tax rate will be expressed with two decimal places. The average effective tax rate is determined according to the following formula:
TMG = Full fee x 100 ÷ Liquidable base
The determination of the part of the taxable base taxed abroad (BLE) will be determined as follows:

From the value of the asset located abroad, the amount of the deductible debts corresponding to it will be subtracted, as well as the proportional part of the debts that, being equally deductible, are not linked to any asset element, thus obtaining the asset amount. net corresponding to said element (PN).

The net asset amount thus determined (PN) will be reduced by the proportional part of the reduction due to the exempt minimum. This operation can be represented with the following formula:
BLE = PN x Taxable base ÷ Taxable base
Note: When the taxable person has more than one asset or right located outside of Spain, the calculation of the deduction will be made individually for each asset or right, transferring the sum of the prevailing amounts to box [41] of the declaration. in each and every one of the individual calculations made.
Example
Ms. VGC, resident in Ávila, presents the following data in her Wealth Tax return corresponding to the 2022 financial year:
 Taxable base: 1,450,000
 Liquidable base: 750,000

Once the net value of the property has been determined, it is reduced by the proportional part of the reduction due to the exempt minimum: (160,000 x 750,000) ÷ 1,450,000 = 82,758.62 euros. ^{(Back)}
^{(2) }The average effective tax rate is determined as follows: (3,240.36 x 100) ÷ 750,000 = 0.43. ^{(Back)}
