Using autosell actually makes you lose gold.

[Zakilevo]

It seems using autosell will make people lose gold if you have an empty estate in your region.

Peasants Taxes   350 gold
Trade Balance   + 200 gold
Collectable Tax Gold   550 gold
Estate of   Size   Peasants   Tax Collected   Knight Share   Lord Share
Kihalin   40 %   5600   221 gold      2210gold
Wild Lands   60 %   8400   165 gold      165 gold
Region Totals         385 gold   0 gold   385 gold

Lord and Duke Shares
Lord Share   385 gold
Dukes Share   - 20 gold
Lords Tax Income   365 gold

I highly doubt this was intended but by making the trade balanced added to the collectible tax, lords are actually losing gold unless you do not have any wild lands or empty estates as you lose a certain percentage of your gold when your collectible gold is distributed to wild lands/empty estates.

Without using the auto-sell offer, I should get 140 + 105 + 200 = 445 gold instead of 385 gold.

I'll have to think about a fix for this. The obvious solution is to apply the Wild Land bane before Trade Balance, but this may be working as intended...
