Taxation of the difference between subscription and nominal value in Government bonds

Managing public debt assets involves specific tax implications that investors must understand to comply with their tax obligations. A recent binding ruling from the Directorate General of Taxes (DGT) has clarified the timing and method for taxing the difference between the subscription amount and the nominal value of Government bonds.

What the DGT has ruled

The query focused on determining the temporal allocation of the difference between the effective auction price of the Government bonds and their nominal value at maturity. The DGT has ruled that this difference constitutes redemption income and is classified as income from movable capital.

The amount of said income is calculated using the following operation:

• Redemption value (nominal value).
• Less subscription value (effective auction price).
• Less duly justified ancillary expenses.

Regarding the timing of taxation, the tax authority establishes that this income must be allocated to the tax period in which it becomes due. In the case of securities held until maturity, this moment is the effective redemption.

What this means for you

If you are an individual holding Government bonds until maturity, the gain obtained from the difference between what you paid to acquire them and the nominal value you receive when the security expires is not immediate income, but is taxed at the time of collection. This income is included in the taxable base of Personal Income Tax (IRPF) as income from movable capital, in accordance with Law 35/2006.

What you should do

It is necessary to keep precise records of the auction amounts and any ancillary expenses that may be deductible, provided you have the documentation to justify them. Since the temporal allocation depends on the moment of redemption or transfer, it is fundamental to ensure that your tax return correctly reflects the fiscal year in which the taxable event occurs to avoid discrepancies with the Tax Administration. It is recommended to assess each particular situation to determine the exact impact on your tax return.
