Market specifics - main provisions

Legal obligations impacting LuxCSD tax services

LuxCSD accesses the Portuguese market via a direct link to Clearstream Europe AG (CEU).

In relation to debt securities within the scope of Decree-Law No 193/2005 of 7 November 2005, as amended (hereinafter “Special Debt Securities’ Regime”, CEU undertakes the role and responsibilities of a Direct Registrar Entity1, affiliated with Interbolsa.

CEU, as a T2S In-CSD, cannot benefit from the Article 17 regime granted only for the ICSDs. Full tax calculation and reporting requirements apply to CEU clients and therefore to LuxCSD clients, as described below.

LuxCSD account structure 

By default, the accounts of LuxCSD clients are flagged as N (non-exempt = taxable).

To be exempt from Portuguese withholding tax on interest from debt securities, clients must segregate debt securities held for exempt and non-exempt investors into at least two separate securities accounts, one taxable and one exempt. Such segregation is mandatory as per the Portuguese law requirements. Clients can hold debt securities for:

  • Exempt investors (for whom the certification procedure has been fulfilled): 
    • In a single “exempt” account (“S” account); or
    • In an omnibus “exempt” account (“X” account). OR
  • Non-exempt investors in another “non-exempt” account (“N” account) including undisclosed positions taxed at maximum tax rate (35%) or disclosed beneficiaries providing information to allow the application of the standard tax rates (25% or 28% tax applicable, respectively, to corporates and individuals).
