Dear SINGTAX Corporate users,

A cumulative service update to SINGTAX Corporate 2026 (Build 26.2.0) has been released. This update includes:

1. Forms->Form C for YA 2026.
2. Forms->Form C-S for YA 2026. However, direct e-filing of Form C-S via API from SINGTAX is not available pending testing with IRAS.
3. Forms->Form C-S (Lite) for YA 2026.

N.B. Re-generate your tax computations for data to populate the forms.

Existing users (using dongles and 1-user software activation) will be prompted to download patch upon starting SINGTAX Corporate 2026.

All other software activation (2 or more) users will receive an email with a link to download the patch.

Dear SINGTAX Corporate 2026 Users,

We need time to implement the new data requirements by IRAS for YA 2026 Form C / C-S / C-S (Lite) into SINGTAX and formulate the relevant data transmission from the respective entry modules into the tax form templates accordingly.

We are targeting to release the Form C / C-S (without the seamless filing function) / C-S (Lite) templates in SINGTAX by 22 May 2026. When this is ready, you will receive an alert (when you log in to SINGTAX) to download an update patch.

We have yet to receive IRAS YA2026 Form C-S API for our Annual Readiness Testing (“ART”) for the seamless filing (which is expected to be released after mid-May 2026). Only upon IRAS clearance of our “ART” will we then receive IRAS approval to release YA 2026 Form C-S seamless filing in SINGTAX. As IRAS is in the midst of migrating their APIs to a new Whole-of-Government API platform (known as APEX Cloud), the Annual Readiness Testing for the YA2026 Form C-S API seamless filing may take up to August 2026 to complete (based on IRAS timeline).

For urgent cases (before Form C-S seamless filing is available in SINGTAX), we recommend for you to login to IRAS myTax Portal to e-file your clients’ YA2026 Form C-S.

We hope for your patience and thank you in advance for your understanding in this matter.

Team SINGTAX.

Dear SINGTAX Corporate Users,

Some users have written in to ask when the latest announced updated CIT Rebate for the Year of Assessment ("YA") 2026 and CIT Rebate Cash Grant will be implemented in the software.

UPDATE: A patch for this will be released early this week.

Some users have also started to ask for Form C/ C-S/ C-S (Lite) features for YA2026. The reason is because clients started receiving notices to e-file Form C-S/ C for YA2026.

UPDATE: Try logging in to IRAS Tax Portal to e-file. You will see a "This form is currently unavailable" message.

The patch for Form C/ C-S/ C-S (Lite) will only be available 2 weeks after e-filing at the IRAS Tax Portal is opened. The reason is we need to check and compare our Forms' entries against the corresponding entries in the Tax Portal to make sure there are no errors before we release the updates.

Therefore, please refrain from sending us emails requesting status updates on the 2 items above.

We check IRAS website everyday. We are also a digital partner of IRAS and IRAS will update us when there are changes.

Thank you for your patience and understanding.

Most of all, thank you all for your wonderful support for SINGTAX all these years .

Team SINGTAX.
