Share: Share to Wechat

“Uploading of Data Files for Supplementary Forms and Supporting Documents to Profits Tax Return” electronic service (the Uploading Service) allows users to upload supplementary forms, financial statements and tax computation.  In addition, this service provides printing of Control List for electronic file for supplementary form uploaded (the Control List) for submission together with the Profits Tax return in paper form.

Uploading of supplementary forms

All uploaded supplementary forms will be compressed to a zip file for transmission automatically.  Please keep it for record.

Uploading of financial statements and tax computation

If you file the Profits Tax return electronically, the financial statements prepared in accordance with full Hong Kong Financial Reporting Standards / Hong Kong Financial Reporting Standard for Private Entities / Small and Medium-sized Entity Financial Reporting Framework and Financial Reporting Standard, and tax computation to be uploaded should be prepared in inline eXtensible Business Reporting Language (iXBRL) format and in accordance with the IRD Taxonomy Package.  In other cases, uploading financial statements in PDF format would be only accepted where the financial statements are prepared in accounting standards other than the above.  Please click here for more information.

The uploaded financial statements and tax computation will be compressed to zip files automatically.  Please keep them for record. 

Printing of Control List

In case your tax return and Supporting Documents are submitted in paper form, please print and sign the Control List (with QR code) for the supplementary form uploaded and submit the Control List together with the Profits Tax return. The Control List must be signed by the same person signing the tax return. If the tax return is submitted under the electronic filing or semi-electronic filing mode, please proceed to the Completion Service and the Submission Service directly without the need to print the Control List. These services will link up the uploaded data files with the relevant Profits Tax return.

If the duly completed Profits Tax return is not submitted to the Department either in paper or electronic form, mere uploading of the data file via this service will not be regarded as having complied with the return filing obligation stipulated in the Inland Revenue Ordinance.
