Item 8.01.  Other Events.

On April 18, 2005, Barrett Business Services, Inc. (the "Company"),  announced a
three-for-two  split of its common  stock,  to be  effected  in the form of a 50
percent  stock  dividend.  The stock  dividend,  which was declared on April 15,
2005,  will be paid on May 19, 2005, to  stockholders  of record at the close of
business on April 29, 2005. Each  stockholder  will receive one additional share
for every two  shares  owned.  Cash will be paid in lieu of  fractional  shares,
based on the closing  price of the  Company's  common  stock on the record date,
adjusted for the stock split.  Following the stock split,  the Company will have
approximately 8.7 million shares of common stock  outstanding.  The par value of
the  common  stock will  remain  $.01 per  share.  The  common  stock will trade
"ex-dividend" beginning on May 20, 2005.

Pursuant to Rule 416 of the Securities Act of 1933, as amended, effective on the
record date for the stock split,  April 29,  2005,  all  effective  registration
statements  relating to the  Company's  common stock will be deemed to cover the
additional  shares  resulting  from  the  stock  split,  including  Registration
Statements on Form S-8, Nos. 333-105833 and 33-33487.
