We didn’t allow the amount claimed as excess Social Security tax or tier 1 RRTA withheld on your tax return because Form(s) W-2 was not attached to your tax return. No le concedimos la cantidad reclamada de la retención del exceso de la contribución del seguro social ó lo dispuesto en la retención del RRTA 1 en su planilla de contribución, porque la/las Formulario(s) 499R-2/W-2PR no fueron incluídas a su planilla contributiva.
