Form 12BB — employee investment declaration
The statement you give your employer listing the deductions and exemptions you intend to claim — rent, home loan interest, investments, leave travel — so the right amount of TDS is deducted from your salary. Issued and governed by the Income Tax Department (CBDT).

Who files Form 12BB
Salaried employees, once a year, submitted to the employer rather than to the department.
When
Usually collected by payroll in the last quarter of the financial year, with proofs attached.
The thing people get wrong
This is the moment the proofs get scanned and emailed, and the attachments are rent receipts with a landlord's PAN, loan statements and bank details. Payroll portals cap the upload size, which is how those documents end up going through a random online compressor.
Where to get the current Form 12BB
From your employer's payroll team. Income Tax Department (CBDT). We deliberately do not host a copy of any government form. They are revised without notice, and a stale file served from here would be worse than none — you would file it and find out months later.
The tools people need around Form 12BB
Form 12BB is filed with the authority, not with us. What we do is the document work around it — the part where a payroll portal caps uploads at a few megabytes, or two certificates have to become one file, or a statement has to become rows you can total.

Can DiemDesk file Form 12BB for me?
No, and nothing here does. We are document tools, not a filing service. What we help with is the paperwork around the filing — combining certificates, compressing a scan under a portal's upload limit, turning a statement into a spreadsheet, or redacting an account number before you forward something. All of it runs in your browser.
Are my documents uploaded?
No. The in-browser tools open and rebuild the file on your own device, so a Form 16 or a bank statement never leaves it. Open your browser's Network tab and you will see no request carrying the file.
