Step by step

How to stay ahead of STP Phase 2. Seven steps.

Every step links to the corresponding input above.

  1. 1

    Confirm your pay cycle

    Identify whether your business runs weekly, fortnightly, or monthly payroll. XIntelliSync supports all three — the calculator above covers each.

  2. 2

    Confirm your last pay date

    Note the most recent date employees were paid. This anchors the calculation for your next STP deadline.

  3. 3

    Check your employer size

    Employers with 5+ employees lodge STP per pay run. Employers with 1-4 employees using a registered tax agent may qualify for quarterly concessional reporting.

  4. 4

    Review the next STP deadline

    The calculator shows your next pay date and the STP report due date — they are the same for standard employers (on or before pay day).

  5. 5

    Prepare payroll data before pay day

    All payroll figures — gross, tax withheld, super, country codes, income types — must be finalised before lodgement. XIntelliSync prepares this automatically if you use the platform.

  6. 6

    Lodge via your payroll lodgement path

    Submit the STP Phase 2 report via your payroll software or through your registered tax agent. XIntelliSync does not lodge directly — we prepare the data for your lodgement system.

  7. 7

    Track the quarterly super deadline

    Super Guarantee contributions are due quarterly (28 Oct / 28 Jan / 28 Apr / 28 Jul) until Payday Super takes effect on 1 July 2026, when SG is paid same-day as wages.

STP Phase 2. Questions answered.

When is STP Phase 2 due?+
Single Touch Payroll Phase 2 reports must be lodged on or before each pay day for standard employers. The ATO treats "on or before pay day" as the compliance boundary — lodge before you pay employees, not after. There is no grace period unless you qualify for micro-employer concessional reporting.
What is micro-employer concessional reporting?+
Employers with 1-4 employees using STP reporting through a registered tax agent may qualify for quarterly STP reporting instead of per-pay-run. The deadlines align with BAS quarters: Q1 due 28 October, Q2 due 28 February, Q3 due 28 April, Q4 due 28 July. Registered tax agents may also have an additional 2-week extension.
What happens if I miss an STP deadline?+
The ATO applies Failure to Lodge (FTL) penalties — approximately $313 per 28-day period overdue (2026 penalty unit). General Interest Charge (GIC) also accrues on any related tax liabilities from the due date. Consistent late lodgement can trigger ATO review and removal of STP concessional treatment.
Does XIntelliSync lodge STP for me?+
No. XIntelliSync is not a registered ATO Digital Service Provider. Every pay run prepared by XIntelliSync is STP Phase 2 compliant — income types, country codes, disaggregated gross, child support deductions all reported to ATO specification — but you lodge through your connected payroll lodgement path or registered tax agent.
What is Payday Super and when does it start?+
Payday Super is the 2026 Australian superannuation reform requiring Super Guarantee contributions to be paid on the same day as wages, not quarterly. It takes effect from 1 July 2026. Existing quarterly due dates (28 October, 28 January, 28 April, 28 July) apply until then. XIntelliSync tracks the transition automatically on every pay run after the effective date.
How does XIntelliSync help me never miss an STP deadline?+
XIntelliSync tracks every pay run automatically from your live bank feed and payroll records. Every scheduled pay date has its STP preparation ready before the cycle starts. When a pay run is due, the STP Phase 2 payload is prepared and waiting for your review + lodgement submission — no last-minute scramble.
What STP Phase 2 changes from Phase 1?+
Phase 2 expanded the data reported to the ATO per pay run: income types (salary, bonus, paid leave, parental leave), country codes (for foreign tax), disaggregated gross amounts (salary + overtime + allowances split out), child support deductions, lump sum categories, and employment termination details. Every XIntelliSync payroll preparation is Phase 2 compliant out of the box.
Tracking deadlines is free. The automation is $97/mo.

The calculator tells you when. XIntelliSync does the prep.

Every pay run prepared automatically with STP Phase 2 payload, super calculation, and Payday Super transition logic — reviewed by you, lodged through your path. Included in every plan from $97/month AUD.
