Tiling over plasterboard, need to tape?

I'm re-doing our bathroom and I'm lining the walls with square edge plasterboard over 2x2" battens. I know the plasterboard needs to be primed before tiling, but do I need to tape and fill the joints? TIA

No harm in taping may improve the surface. but plasterboard is a poor product to use around baths and showers. I would use proper tile backing board in those areas
