If you’re rental is a single family, you can get the parcel # from zillow or redfin.
Then use that (rather than the address) to look up the property on the county website. Put the parcel # in for the bill # field on the sdtreastax website.
You can also see if a lien has been placed against your landlord by going to sdarcc.com and doing a grantee/grantor search. Put in the landlord’s name. That would show previous year’s liens for property taxes (or other taxes) – but liens for the new defaults haven’t been recorded yet for this year.
(I’m working on becoming a super-sleuth, trying to figure out if it’s worth going after our former @#$# contractor that abandoned our project. Public records show him to be a widely varied deadbeat… so if we sue him, it will be for moral victory more than anything.)
