Treated posts sitting on concrete or metal standoffs, so the wood isn't in
direct ground contact. You do need to tie it down so it doesn't blow away.
Mobile home anchors, or if you want to get fancy, have a welder make some
square-section tubes to slip the legs into, with big augers like used for
huge dog tiedowns attached to them (or even just bigass metal stakes), and
holes for horizontal bolts through the uprights. Or, like the other guy
said, just plant the posts like fenceposts or mailbox posts, cut the tops
off even, and frame it up from there. I don't think things without solid
roofs and/or panels (like sheds or fences) are considered 'structures' in
most areas. Drive around the neighborhood, and see what the neighbors have
put up- you can probably get away with the same.

You can also buy precast foundation plinths that may or may not be taken as
"permanent" by your local tax office.

Personally, I'd set to sonotubes deeply enough to cover them with soil and
have a galvanized bracket set into them sticking up out of the ground.
Tell the tax inspector that the bracket is just driven into the ground.

anything that is 121 sq.ft. or more is taxed.
whether attached or not.
concrete filled or sand filled - doesn't matter

that's why my dog house, garden shed and tool shed are exactly 120 sq.ft

You forgot to say 'around here' at the start of that. Property tax rules and
enforcement practices vary greatly by state, county, and even township/city.
Around here they use the 'permanent foundation' rule, which is usually
interpeted as slabs or poured piers. Precast piers usually slide, even if
below grade level. Lotsa people have wood-floor sheds on precast deck
blocks, over gravel, even when a slab would have made better engineering
sense and avoided a ramp. I'm lucky- out here in the township, enforcement
is very spotty. My metal shed screwed to the slab floor of an abandoned dog
pen is apparently invisible, tax-wise, since the chainlink pen is still
surrounding it. (all work of the previous idiot owner, but it works well
enough for my current needs.)
