WTF! DIONNE WARWICK OWES $10 MILLION IN BACK TAXES

Dionne Warwick is broke as hell ... like "Nic Cage" broke ... and owes more than $10 million in unpaid taxes, this according to the singer's rep.

The "Do You Know the Way to San Jose" singer filed for bankruptcy in New Jersey claiming she only had $25k in assets ... but owes more than $10.2 million in taxes and fees to the IRS and the State of CA.

Warwick's rep, Kevin Sasaki, says Dionne's financial disaster was caused by "negligent and gross financial mismanagement" in the late 1980s through mid-1990s.

According to the court docs, the 72-year-old claims she makes $20,950 ... but spends $20,940. Translation -- her monthly net gain is TEN DOLLARS!!

Warwick claims she only makes $1,000 per month from music royalties.

In the docs, the 5-time Grammy winner says she's still in possession of the following assets:

-- 2 fur coats
-- 2 pair of diamond earrings
-- various gowns (worth $5k)
-- living room furniture, dining set, bedroom sets, over 10 YEARS OLD

Warwick says she spends $5,000 per month on housekeeping ... and $4,000 per month on a personal assistant.

Warwick's rep offered the following explanation -- "In light of the magnitude of her tax liabilities, Warwick has repeatedly attempted to offer re-payment plans and proposals to the IRS and the California Franchise Tax Board for taxes owed. These plans were not accepted, resulting in escalating interest and penalties."
