Needless to say / It goes without saying

[Tomisimo]

Any good ways of expressing these phrases in Spanish?

Needless to say...
It goes without saying...

Thanks in advance.

I'm sure Sosia, Iris and Alfonso have a better term, but I would translate
"that goes without saying" in the following manner: es implícito.
I also think you can say ni tiene que decirlo.

For the phrase 'that goes without saying,' I agree that es implícito works, but it is more popular to say ni que decir tiene.

A neat way to say 'needless to say' is huelga decir. Another is obvia decir.

You can also say de más está decir.

[sosia]

implícito is a good word, but not usually used in this context.
I would use Rusty's options and some more:
-huelga decir
-ni que decir tiene
-es obvio ..
-No hay que decir ...
-Obvia decir ...
-está de más decir.....
-de más está decir....
-supongo que no será necesario comentar....

saludos

[Alfonso]

Everything is already said. Anyway, here are my options:

• no hace falta decir que...
• está de más decir que...
• no hay ni que decirlo...

And I would like to point out:

• huelga decir sounds to me formal and old fashioned.
• If you use implícito it goes with estar: está implícito en el contexto...
• I would say that obvio and implícito have different meanings, but you can also think how you use their literal translations in English and decide if they are synonyms or not.

[sosia]

other option:
"por supuesto que ..."
It's not a formal translation, but is widely used.

Thanks to everyone, you've given me some great options to work with.

[Iris]

I would also say "se sobreentiende".

[Tomisimo]

That's also a good option Iris, thanks. Going the other direction, I usually translate se sobreentiende as it's understood.

Needless to say, they are also invited.

Demás está decir, ellos también están invitados.
