Who can access the service
Published 21 January 2026, the guide concerns third-party intermediaries reporting self-employed persons’ income through myTax Portal where they are not using software integrated with the relevant API. The organisation must participate in submission/pre-filling of self-employment income and the staff member must hold the Corppass Preparer or Approver role for Submission of Self-Employment Income Records. Log in under Company/Business Tax using Singpass app or password and 2FA, then More, e-Submission, Submit Self-Employment Income Records. The landing page offers income submission, nil return and viewing earlier submissions.
Contact information and submission choices
Create starts the workflow. New intermediaries or those without contact details are redirected to Update Contact Details; complete required fields, agree to terms and Save Changes. Existing intermediaries verify saved details and use the contact-update link if needed. After its acknowledgement, return through More and Create; updating contact information is not an income submission. Select the income year, intermediary type where registered for several types, and Submit new (original) records. Choose individual entry for up to 200 records per submission or the Excel template for up to 2,000. The displayed 2025 income/YA 2026 is an example.
Individual records: identity and gross income
Add New Records opens entry. Select NRIC, FIN, passport or UEN and enter the matching number and full name as in the identification document or ACRA record. Individual date of birth is entered with the calendar or DD/MM/YYYY; UEN records do not display this field. Commission-paying organisations also select the activity, such as real-estate or insurance agency. Enter gross income before expenses, drop cents rather than rounding and omit non-numeric characters: both S$50,221.43 and S$50,221.98 become 50221. The field accepts at most eight digits. Add New permits ten records at a time; Update saves them before opening another set. Match each identity with its income.
Review manual entries or upload the Excel template
The manual summary displays 20 records per page; navigate pagination to review all. Edit or Delete corrects entries, Save Draft preserves work and Continue advances to submission. Download the service’s Excel template and save the completed file as .xlsx. Only one file per submission, at most 10.00 MB, up to 2,000 records, with an English filename no longer than 50 characters. Split larger sets into separate batches. Select File, View Errors and Export All Errors where necessary; correct the original workbook, save and re-upload. Continue only after validation succeeds.
Submit records and distinguish internal approval
Review the submission summary and use Edit for corrections. The contact person is prefilled from self-employment income contact details; change it if someone else handles this submission. Acknowledge the declaration and Submit. An Approver’s successful filing generates an acknowledgement number. A Preparer’s submission goes to the Approver and has no acknowledgement number at that stage. Save as PDF/Print or retrieve through View Notices. The link at the bottom returns to the service landing page. Saving a draft or passing an upload check does not replace these final steps.
Nil returns and retrieval periods
For a nil return, select the correct income year and, if prompted, intermediary type, then Submit NIL Return. Verify the declaration that the organisation has no self-employment income records to submit for that year, Continue, review contact details, acknowledge the declaration and Submit. The same Preparer/Approver distinction applies. Submitted records can be viewed for the current YA, one advance YA and four past YAs; select the year and View. On-screen pagination shows 20 records at a time, while Save as PDF/Print includes all submitted records.
