How do I get Vassals to pay?

[Sunsanvil]

Not quite sure which mechanic I'm missing an understanding of but when I survey my vassals, I don't understand why I get a bit of cash from a few, but 0 from most. I thought it was opinion based but I'm looking at several with a +100 opinion of me who are remitting nada.

Laws define how much they are meant to pay, opinion how much of that they actually do.

 

[Naughtius Maximus]

Also without Conclave your Feudal vassals tend to not pay anything whatsoever, at least not in terms of cash. You either have to vote to tax them yourself or get Conclave.

If feudal tax is set to none then 100% opinion won't change what feudal vassals pay. Same goes for city tax and cleargy tax. Make sure the law requires them to pay and you can view how much each pays by clicking on your primary title and mousing over the different entries (e.g. "feudal tax, city tax) down where it says income. If opinion is influencing what they pay, it shoudl say so.
