One distinction explains a surprising amount of uncollected money in music: publishing royalties are conventionally divided into a writer’s share and a publisher’s share. If you’ve written songs but never signed a publishing deal, it’s easy to assume there’s no “publisher” in the picture — but the publisher’s share doesn’t disappear. It’s still yours to claim, and a lot of self-published artists collect only the writer half without realizing the other half is sitting there.

This guide explains what the two shares are, why the split exists, and how to make sure you’re collecting both. Because the amounts depend on your works and registrations, we keep it qualitative and point you to the Publishing Royalty Recovery Diagnostic for a structured read.

Where the split comes from

Publishing income is built on the composition copyright — the song itself, as opposed to the recording. For more on that foundational split, see Music Publishing Explained.

Historically, songwriters signed their compositions to a publisher, who administered the song and collected its royalties in exchange for a share. To formalize that arrangement, royalties on the composition were divided into two conventional halves:

  • The writer’s share — the portion associated with the songwriter as creator.
  • The publisher’s share — the portion associated with the publisher who administers the work.

This convention persists even when the writer and publisher are the same person. When you self-publish, you are effectively both — so both shares belong to you.

Why this matters for self-published artists

Here’s the trap. Some collection setups, by default, are oriented around the writer’s share. If you affiliate with a PRO purely as a writer and never establish yourself on the publishing side, you may collect your writer’s share of performance royalties while the publisher’s share goes uncollected. Multiply that across performance royalties, mechanicals, and other pools, and the gap is meaningful.

The fix is to make sure you’re set up to collect both shares — typically by registering as a publisher (or self-publishing entity) in addition to being registered as a writer, and by capturing the publisher portion in each collection system. This applies on the mechanical side too — see What Are Mechanical Royalties?.

How the shares show up across royalty types

The writer/publisher split runs through several royalty types, each collected by a different body:

  • Performance royalties (collected by PROs) typically pay a writer’s share and a publisher’s share. Self-published writers need to be positioned to collect both. See Choosing a PRO.
  • Mechanical royalties (in the US, via The MLC) are also tied to the composition and involve the writer/publisher relationship. Registering correctly captures the full amount — see How to Register With the MLC.
  • International royalties add further complexity, because foreign societies and sub-publishers handle the publisher side abroad — see How to Collect Your International Royalties.

The recording-side royalties (neighbouring rights, SoundExchange) are a different axis entirely — they’re not part of the writer/publisher composition split.

Self-publishing vs. signing to a publisher

Once you understand the two shares, the decision about whether to use a publisher comes into focus:

  • Self-publishing means you keep both shares but take on the administration yourself — registrations, matching, international collection, and chasing.
  • Signing or using an administrator means giving up a share (or paying a commission) in exchange for someone handling that administration and, importantly, reaching pools you’d struggle to reach alone, like international and Content ID.

That’s a genuine trade-off, not an obvious win either way. We weigh it in detail in Do I Need a Publishing Administrator?. Note that a publishing administrator is different from a traditional publishing deal: an admin generally helps you collect for a commission without taking ownership of your copyrights, whereas a deal may involve assigning rights.

Don’t confuse shares with splits

A common point of confusion: the writer/publisher share is not the same thing as the songwriting splits between co-writers. Splits decide how the writer’s share (and the publisher’s share) is divided among the people who wrote the song. The writer/publisher distinction sits on top of that. You need both right: correct co-writer splits and collection of both the writer and publisher shares. For splits, see How to Split Songwriting Royalties Fairly and Split Sheets.

Frequently asked questions

If I never signed a publishing deal, do I still have a publisher’s share? Yes. The publisher’s share exists whether or not there’s a separate publisher. If you self-publish, that share belongs to you — but you generally have to be set up to collect it, not just the writer’s share.

Am I automatically collecting both shares if I’m registered with a PRO as a writer? Not necessarily. Writer-only registration can leave the publisher’s share uncollected. Establishing yourself on the publishing side is how you capture both. See Music Publishing Explained.

Is the writer/publisher split the same as my co-writer splits? No. Co-writer splits divide the song among the people who wrote it. The writer/publisher split is a separate convention that applies on top. You need both correct.

Does this affect mechanicals as well as performance royalties? Yes. The composition side broadly carries the writer/publisher relationship, including mechanicals via The MLC. Registering correctly captures the full composition-side amount.

Should I self-publish or use an administrator? It depends on how much administration you want to handle and whether you need to reach international and Content ID pools. The trade-off is covered in Do I Need a Publishing Administrator?.
