  • Correct an activity statement

    You can use your current activity statement to:

    • correct goods and services tax (GST) mistakes
    • correct fuel tax credit mistakes
    • make claims for previous periods
    • vary instalment amounts.

    A four-year time limit applies to claiming credits and refunds.

    Time limits also apply for varying instalment amounts. Corrections must be made:

    • on or before the day your instalment is due
    • before you lodge your tax return for the year.

    The process for correcting mistakes and making claims for previous periods depends on the specific tax, credit involved and time limits.

    If you can't make a correction on your current activity statement, you may be able to revise the original activity statement. See Revising an earlier activity statement.

    We can also make mistakes processing your activity statement – for example, it may scan incorrectly, or we may make a keying error. If you think we've made an error, contact us.
