In the common case of receiving a compressed tar over the network, it should hopefully be protected by at least a checksum or hash, if not a cryptographic signature.
If I expect I may have to deal with some form of data corruption (such as long-term archival media), I'd rather add a layer such as PAR2 [0]. Rather than content myself with "if the tar file is corrupted, I can probably recover most of the contents", erasure coding gives me confidence that I can definitely recover all of the contents, with confidence they're not corrupted, as long as I have enough parity data.
