How come Bitstamp Limited haven't filed their first accounts yet??
The incorporation date was 25 July 2012. Aren't you overdue?
As per Companies House, you have 21 months:
6. How long do I have to file my company's first accounts?
If you are filing your company's first accounts and those accounts cover a period of more than 12 months you must deliver them to Companies House
within 21 months of the date of incorporation for private companies or
within 18 months of the date of incorporation for public companies
or 3 months from the accounting reference date, whichever is longer. The deadline for delivery to Companies House is calculated to the exact day.
