Why do I have to pay backed for life, if my tax return is a simple W2?

¿Por qué tengo que pagar respaldado de por vida, si mi declaración de impuestos es un simple W2?

We do not have enough information to be able to assist you.  

What do you have to 'pay backed for life'?

Please clarify.

If your employer is not taking enough tax out of your paycheck then you have to pay taxes later.  

Si su empleador no está sacando suficientes impuestos de su cheque de pago, entonces usted tiene que pagar impuestos más tarde.
