If you want Walmart to collect sales taxes on your behalf certain settings are to be adjusted at Seller Center level. As the Walmart uses tax engine which calculates tax on your behalf whenever an item is sold. Also, the sales engine takes into account any sales tax changes.
Thus, if you want to benefit from this feature and save yourself from some head scratching conditions (they certainly can be, since each state has its own codes and to make matters more complicated, even the counties can have their sales tax code), then you need to follow some points:
