What this form asks for

The AI fills all of it, from your answers or your documents.

The SU599, or Assurer's statement to Centrelink, is a mandatory document for individuals in Australia who have given an Assurance of Support (AoS) for a migrant. This form is used by Centrelink to review the assurer's financial capacity and to verify that they are meeting their obligations to support the sponsored person, which is crucial for the assuree's eligibility for certain social security payments. Today, this form can be filled out quickly and accurately using AI-powered services like Instafill.ai, which can also convert non-fillable PDF versions into interactive fillable forms.

The AI checks your answers before you download

14 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.

Conditional Employment Details Requirement

This check ensures that if the user selects 'Yes' for 'Employment Details', then the 'Weekly Earnings Before Tax', 'Employer Name', and 'Employer Address Line 1' fields are mandatory. This is crucial for verifying the user's financial capacity and employment status as declared. If these fields are empty after selecting 'Yes', the form submission will be blocked with an error message prompting the user to provide the required employment information.

Exclusive Selection for Yes/No Questions

Verifies that for each pair of 'Yes' and 'No' options (e.g., Employment Details, Property Income), only one can be selected. This prevents contradictory or ambiguous data entry that would make processing the form impossible. If both or neither are selected for a required question, the user will be prompted to make a single, valid selection before proceeding.

Date of Birth Format and Plausibility

Ensures the 'Date of Birth' for both the assuree and the user is entered in a valid format (e.g., DD/MM/YYYY) and represents a realistic date in the past. The validation should also check that the date does not indicate an age younger than a plausible minimum, such as 18 for the user signing the declaration. This prevents data entry errors and ensures the user meets age-related eligibility criteria.

Customer Reference Number Completeness

Validates that all four segments of both the 'Assuree's Customer Reference Number' and 'Your Customer Reference Number' are filled in. These numbers are critical identifiers, and incomplete entry would prevent the system from correctly linking this form to the right accounts. If any segment is left blank, an error will be displayed, requiring the user to complete the full reference number.

Contact Phone Number Format

Checks that the 'Contact Phone Number' field contains a string that matches a valid phone number format, including an appropriate number of digits. This is crucial for ensuring the organization can contact the user if there are any issues with their submission or for follow-up questions. An invalid format will trigger an error message asking the user to correct the number.

Conditional Property Income Details

This rule enforces that if a user checks 'Yes' for receiving 'Property Income Details', the 'Gross Weekly Rent' field must contain a valid, positive numeric value. This ensures that declared income sources are properly quantified for financial assessment. Failure to provide the rent amount after indicating property income will halt submission and require the user to enter a valid monetary value.

Common Mistakes in Completing SU599

The ones the AI is built to catch.

Mixing Up 'Assuree's' and 'Your' Reference Numbers
The form requests two separate, multi-part reference numbers for the 'assuree' and the applicant ('you'). Users often get confused and enter their own number in the assuree's section or vice-versa, leading to an immediate data mismatch and rejection. To avoid this, carefully read the section headings and double-check that you are entering the correct number for the specified person before submitting.
Reporting Net Income Instead of Gross
The form explicitly asks for 'Weekly Earnings Before Tax' and 'Gross Weekly Rent,' but people often enter their net (take-home) pay out of habit. This provides an inaccurate financial picture and can lead to an incorrect assessment of eligibility or capacity. Always refer to your payslip or financial statements to find the gross amount before any deductions are made.
Inconsistent Yes/No Selections and Details
A common error is checking 'Yes' to a question (e.g., 'Are you employed?') but failing to fill out the required detail fields that follow. This logical inconsistency can halt processing and lead to delays or rejection. Ensure that for every 'Yes' answer, you provide all the requested details, and for every 'No,' you leave the corresponding detail fields blank.
Entering an Ambiguous Date Format
The 'Date of Birth' field does not specify a format (e.g., DD/MM/YYYY vs. MM/DD/YYYY), which can cause the day and month to be swapped for dates between the 1st and 12th. An incorrect date of birth is a critical error that can cause identity verification to fail. To prevent this, always use a clear and unambiguous format like DD/MM/YYYY, or use an AI form-filler like Instafill.ai which can automatically format dates correctly.
Failing to Distinguish Between Permanent and Postal Addresses
The form has separate sections for permanent and postal addresses, but users sometimes fill in only one or copy the same information for both, even when they differ. This can result in important correspondence being sent to the wrong location, causing significant delays. Carefully enter the full, correct address for each section, and if they are the same, fill out both sections completely rather than leaving one blank.
Forgetting to Sign or Date the Declaration
The signature and date on the declaration are legally required to certify that the information provided is true and correct. Forgetting to sign or date the form is one of the most common reasons for immediate rejection, as it renders the entire submission invalid. Always perform a final review of the form before submitting, paying special attention to the signature and date fields at the end.
Using Nicknames Instead of Full Legal Names
The form asks for names 'as it appears on official documents,' but people may habitually write a nickname or a shortened version (e.g., 'Bill' instead of 'William'). This creates a mismatch with official records and can cause significant delays in identity verification. Always use your full legal name, including any middle names, exactly as it appears on your passport or birth certificate.
Providing Monthly Income for Weekly Fields
Several fields specifically request a 'weekly' amount for earnings and rent, but users often mistakenly enter their more familiar monthly or fortnightly figures without converting them. This drastically skews the financial assessment and will lead to rejection. You must calculate the correct weekly equivalent by dividing your fortnightly income by 2 or your monthly income by 4.33.
Omitting 'Other' Income Sources
When faced with sections like 'Other Income Status,' people may overlook or forget to declare smaller or irregular income streams, such as freelance work, investment dividends, or allowances. Omitting any income source can be seen as a misrepresentation and may lead to penalties or the rejection of the application. It is crucial to carefully consider and declare all forms of income you receive, no matter how small.
Using Estimates for Precise Financial Details
Fields like 'Amount Owing' on a mortgage or bank 'Account Balance' require exact figures for an accurate financial assessment. Users may be tempted to provide a rounded number or an old estimate from memory, which creates discrepancies during verification. To avoid this, consult your most recent bank or mortgage statements to get the precise, up-to-date figures before filling out the form. AI-powered tools like Instafill.ai can help by securely connecting to financial accounts to fetch and fill this data accurately.
Incorrectly Entering Segmented Reference Numbers
The customer reference numbers are broken into four separate fields, which increases the chance of transcription errors. Users might skip a segment, transpose digits, or enter parts of the number in the wrong boxes, which guarantees a lookup failure. To prevent this, enter the number segment by segment and then read the full number across the boxes to verify it matches your source document. If the form is a flat PDF, a tool like Instafill.ai can make it fillable, reducing such errors.

What is the purpose of this form?
This form appears to be a review or declaration related to an Assurance of Support. It gathers your current financial information to assess your capacity to support the person (the 'assuree') for whom you've provided this assurance.
Who is the 'assuree' and who am I in the context of this form?
The 'assuree' is the individual you have sponsored or signed an Assurance of Support for. You are the person filling out the form, providing your own personal and financial details.
Where can I find the Customer Reference Number?
The Customer Reference Number is a unique identifier provided by the government department handling your case. You can typically find this number on any letters or official correspondence you have received from them.
What is the difference between my 'Permanent Address' and 'Postal Address'?
Your permanent address is where you physically live, while your postal address is where you receive mail. If you receive mail at your home, these addresses will be the same; if you use a P.O. Box, they will be different.
For income fields, should I enter the amount before or after tax?

What if I have more than four bank accounts or income sources?
The form provides space for up to four entries in these sections. You should list your most significant accounts or income sources; if you need to declare more, you may need to attach a separate, clearly labeled sheet with the additional information.
What kind of information should I provide in the 'Reason for Not Providing Assistance' section?
