Two free SMSF messaging providers closed in 2026. Under Payday Super, a dead ESA blocks your contributions

SuperChoice stopped acting as an SMSF messaging provider on 5 May 2026, and Australia Post closed its SMSF Gateway on 30 June 2026. Both were free, both were widely used, and any fund that relied on one now has an electronic service address that points at a service which no longer runs. Until this month that would have been a slow-burning problem. Under Payday Super, which commenced on 1 July 2026, it is the difference between an employer contribution arriving and being sent back.

The message rail, not the money rail

A contribution reaches an SMSF down two separate channels, and both have to be live. The money moves through the fund's bank account, which is the part we covered when Payday Super started at smsfcore.com/blog/payday-super-smsf-double-contribution. The data moves separately, as a SuperStream message, to the fund's electronic service address.

The ESA is an alias registered with the ATO. It routes the SuperStream message to a messaging provider, who passes the data to the fund so the contribution can be matched to a member. Contributions, rollovers into or out of the fund, and release authorities all travel this same rail. If the alias still points at a provider that has switched the service off, the message has nowhere to land, and a contribution without its matching message cannot be processed.

Why a dead ESA is now an immediate problem

Before 1 July, employer super moved quarterly. A broken ESA discovered in the September quarter could be fixed before the next payment cycle, and most trustees never tested the address between lodgements. Payday Super removes that slack. Compulsory employer super must now reach the fund within seven business days of each payday, so a fund on a fortnightly payroll has twenty-six delivery attempts a year instead of four. A dead ESA fails every one of them.

There is a second checkpoint worth knowing about. From 1 July 2026 an employer can run a Member Verification Request through the ATO before making a first contribution to a fund, to confirm the fund can accept it. A fund whose ESA no longer resolves can fail that check at the front door, before a cent is sent. The member sees a contribution that simply never appears; the employer carries the shortfall and the charge the ATO applies when a payment is late.

The three-business-day rule that is not yours

Some of the Payday Super commentary tells trustees their fund has to allocate a contribution within three business days of receiving it. That figure is real, but it is not the SMSF's. The Payday Super regulations cut the allocate-or-return window for large APRA-regulated receiving funds from twenty business days to three. Self-managed funds were carved out of that change.

An SMSF still has up to 28 days after the end of the month in which a contribution is received to allocate it to a member or return it, under regulation 7.08, exactly as before. What changed for a self-managed fund is not the internal deadline. It is whether the contribution can arrive at all, and that is the part the ESA governs.

What to check this month

The check is quick, and it is worth doing even if your fund thinks its address is fine.

Confirm your provider is still on the ATO's Register of SMSF messaging providers. If your ESA was issued by SuperChoice or Australia Post, it has already stopped working, and any contribution or rollover sent to it will fail.

A fund can hold only one ESA with the ATO. If you need rollovers or release authorities as well as employer contributions, choose a provider that offers all of them, because some newer entrants are contributions-only. Updating the address means registering with a listed provider for a new alias, recording it with the ATO through your administrator, tax agent, myGov, or the paper form NAT 3036, and then telling your employer the new address so payroll sends to the right place.

One point catches funds that receive no employer contributions at all and assume none of this applies. Release authorities travel the same rail. The authority the ATO issues to release an excess-contributions or a Division 296 liability from super is delivered to your ESA, so a member who elects to have a Division 296 amount paid from their fund still needs a working address for it to reach. We set out how that liability is worked out at smsfcore.com/div296.

What we track

SMSF Core records each member's contributions as they land and shows the running position against the caps, so a contribution that never arrives is visible as a gap rather than discovered at year end. The seven-business-day deadline for any given payday can be checked at smsfcore.com/tools/payday-deadline, and there is a sample fund at app.smsfcore.com/demo if you want to see the contribution view with data already in it.
