Let's start with your question :
So would taxes still be required to make this society function now that all money and produce are controlled by the state, can be 'freely' created, and [money] serves moreso a moral goal rather than to pay for things?
Tax what ?
The state gives the money in the first place (why it uses money is another question, as money implies choices driving an economy it does not control). In most countries States operate what are known as PAYE systems, meaning Pay As You Earn, but that applies to economies where all payments (the majority in fact) are made by someone other than the Government. In your case why would the State bother to remove money before it gives it to you ? Or if you give it all and then take it back later that's going to be rather weird.
So, no, taxes just make people confused : *"I'm getting this, but then they take it back ? What ?". It is, however, the kind of thing a centralized monolithic bureaucracy would do simply because it can and no one can stop or has a reason to.
So now it's Frame challenge time or ...
Start the Revolution Now !
Your idea has problems. They're called "humans". :-)
All of Earth's resources can be accessed since the planet is united under a single government body.
Note that "all of Earth's resources" would include people who are not motivated by a sense of social sharing and unification. "All" would inevitably include people who actually loath that system and want some wide range of other systems. Unless you remove free will, that is inevitable, so "all" is not quite correct.
Also some of those resources will turn out to be in places they cannot be accessed without social or environmental problems - moving large numbers of people, interfering with water flows, etc, etc. So again, "all" won't be available.
Even if all are available that does not mean that some resources will not be scarce. And these may not be luxuries, but basic amenities like food and water - we have a tendency to increase the population without reference to practical resource availability. So this model needs population controls to work.
All services, goods, and [digital] money are owned, created, and distributed by the government.
Stagnation would seem likely, as there is no need for development of anything but basic necessities. The State (as an institution) has no need for anything but keeping people alive and "calm" (minimal unrest). There's no economic drive to produce new goods and services or to innovate. Governments (a.k.a. bureaucracies) have a terrible track record for this.
Capitalism has many faults, but it's relatively good at driving innovation, but requires some controls (Government) to stop it getting "carried away".
At best your system produces apathy as a social norm. You might want to consider the history of the Rome Empire when thinking about this, or indeed Asimov's "Foundation" books (which really seem to take Rome galactic).
Every step of production and distribution is automated, even the creation and maintenance of the machines.
Practically speaking there is not much today that is not "automated" in the sense of being part of an intricate production-consumption system. However your particular problem here is what do all the people do to maintain sanity, mental health and a sense of self worth ? Without these your people will be a restless mob looking for a purpose, and that's how revolutions are born.
Humans receive a basic income from the state based on their class
Class !!!!
So we have classes, which means we're not all equal and "some people" (i.e. the vast majority as usual) will be lower class and "might" feel that it's unfair that bad luck, accident or birth, etc. makes them lower class.
And where do revolutions start ? The poor sods labelled "lower class" (or who know they are, regardless of label).
And those near the top class ? Do they practice all those arts humans have used to claw their way to the top over history ? Can you avoid bribery, corruption, politics, graft, greed, envy, lust and so on ? Not with humans involved, I think.
A class system would be a terrible weakness.
, which can be raised (or fall) by collecting votes from other citizens
A popularity contest ! Worse and worse.
An infamous fellow was once asked by a young man what skills he though a young man should nurture to prosper. The old man thought for a while and said "Charm", meaning charisma. The young man was a prison guard and the old man was Albert Speer, who used his charm is very anti-social ways, not to mention avoiding the noose he deserved.
My point is that any system where popular vote gets you to a better class (yuch) is weak because popularity does not equate to socially responsibility. "Albert" of course is just an extreme example : our society rewards socially irresponsible and even dangerous individuals all the time based on popularity and as a species it's practically a defining trait.
and surveillance AI judging their contributions and behaviour either positively or negatively.
And who polices the police. :-)
Someone must control that AI. Someone must define what is "good" and "bad". It can't be a popular vote as we've countless historic examples of how popular votes put the most repellent to the top of the heap. So there have to be rules, but what if you're in that unhappy group who are excluded by the rules - no rules are perfect, after all ?
I. M. Banks' Culture novels does depict such a system (run by AIs), but this is well past providing basics - this system provides anything you want, anytime. It's not post-scarsity (as one poster describes your idea), but post-surplus. Your post does not describe such a world.
So is your world one run exclusively by the AI ? Have the AI the "teeth and claws" to enforce what they decide ? They'll surely need some enforcement arm. What happens if you just happen to not agree or to want change ?

money serves more so a moral goal rather than to pay for things?
Money does what ?
Money acts as a medium to pay for good and services. Having more money than someone else as a goal is just creating yet more class divisions. If you cannot do anything with it other than "keep score", then it becomes ago ego and status, not morality or social value.
Morality ? Who defines that ? More rules ? The AI ? A ruling council, or God forbid, the Upper Class ? Is it some hideous dogma written long ago by dead people - a tradition enforced because the society has that as it's sole purpose - and so on to stagnation ?
You might as well start the revolution now. You've plenty of seeds for one.
