Yes. TikTok's bonuses and your TAP increase come from different pockets, so one doesn't cancel the other.
Why they stack
Two payers, two payments:
TikTok bonuses, like seasonal boosts, product promos and special events, are paid by TikTok.
TAP increases come from the links Soco negotiates with brands.
Because they come from different places, they don't replace each other.
What lands in your payout
Both at once: the higher commission from the Soco TAP link, plus any bonus commission TikTok is offering on that product. Using Soco doesn't remove or reduce a TikTok bonus.
