I don't pay my children to do jobs, they are expected just to do them. It si their home, clothes too, and as I see it we are a family and everyone is expected to pull their weight.
My dd is the same as yours, so for example this is what she does, so you are def not unreasonable to expect more jobs to be done:
Makes bed, loads dishwasher, tidies up after meal times, puts washing in the machine, cleans bathroom after use, tidies her room a few tiems a week, makes a simple lunch for herself, she sometimes vacuums, she feeds all the pets daily. Supervised cooking evening meal.
She sometimes washes the car, does a little gardening. So really not a huge amount at all.
If you allow them to become lazy and unhelpful at this age, then you are really setting yourself up for some serious problems once they are teenagers and beyond.
