Amy Winehouse was worth just over £2 million (NZ$3.8 million) at the time of her death.
The Rehab singer - who passed away at her north London home in July at the age of 27 - had two companies, Cherry Westfield and CW Touring, and the accounts have been published.
They revealed Cherry Westfield was worth £2,004,963 at the end of last November, down £20,000 on 2009, while in the same period, the assets of CW Touring shrank from £142,012 to just £8,032.
It seems Amy's fortune had diminished over time as in the 2008 Sunday Times Rich List, she was estimated to have fortunes of £10 million.
In 2009, her fortune was estimated at £5 million, the same as in the 2010 list.
Following Amy's untimely passing, her father Mitch Winehouse is planning to set up a rehab charity in her memory, with the headquarters set to be at her £2.5 million home.
