Tyga -- California's Comin' for Me!

Tyga is getting hit from every angle on the money front.

Kylie's BF just got slapped with a tax lien from the State of California to the tune of $19,124.98. He allegedly shorted the Golden State on his 2009, 2010 and 2011 tax bills.

$20k would ordinarily be chump change for a rapper at his level, but he already owes his landlord $70k in back rent, and has lawsuits piling up.

It's also not the first time Uncle Sam has come after Tyga ... the feds hit Tyga last year with a $100k delinquent bill.
