Myer has offered an apology for comments by chief executive Bernie Brookes, who suggested increasing the Medicare levy to support disabled people could damage company profits.
Speaking at a business conference, Mr Brookes told delegates the estimated $350 annual household increase on the Medicare levy "is something they would have spent with us".
The comments sparked a backlash on social media sites including Twitter, where some users called for a boycott against the company.

A spokesperson for the retail chain wrote on Myer's official Facebook page the company was "very sorry" for any offence.
"We sincerely apologise to those who have been hurt or offended by our comment, and we really want to make it clear that we support the introduction of the NDIS."
"Like many of you, we'll back a scheme like the NDIS that will support the needs of all those affected by disability. We certainly did not intend to offend anyone, and again, we are very sorry."
The apology came after an earlier clarification was posted to the site claiming the business supported schemes that helped those with disabilities but should be funded without an extra tax.
