Who files GSTR-1
Registered taxpayers other than those under the composition scheme and certain specified categories.
When
Monthly or quarterly depending on your turnover and the scheme you have opted into, on due dates published on the portal.
The thing people get wrong
Your buyers' credit depends on what you file here. An invoice missed or entered against the wrong GSTIN is not just your problem — the customer chases it, and correcting it in a later period is slower than getting it right.
Where to get the current GSTR-1
From the GST portal. Goods and Services Tax Network (GSTN). 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 GSTR-1
GSTR-1 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 GSTR-1 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.
