With only two weeks left until B.C. transitions back to the provincial sales tax, there's a big push underway to encourage businesses not to leave registration to the last minute.

The Canadian Federation of Independent Business is coordinating a campaign called “PST Tuesday.”

 Twitter users will be invited to get on board by hashtagging tweets with “PST” and “smallbiz.”

Spokesman Mike Klassen says the delay in registering may be because of the the cost involved.

“Our surveys show about $3,000 on average per business, just in terms of staff training, rekeying things like cash registers and updating software for accounting."

 Half of the more than 100,000 businesses that need to register to collect the PST had done so.
