7. In Pittsburgh (where I live) only city residents are charged income tax

... but the city charges the non-residents a "services tax" if they work in Pittsburgh but live somewhere else. This is justified as reimbursement for public services, road repairs, garbage removal, etc. and it's withheld from paychecks just like state and federal taxes.

I don't know how other cities justify it, but Pittsburgh has been taking a small amount out of every paycheck. Nobody fights it because it only amounts to about $20 per year. I'm retired for 8 years so my number may be off a little, but not much. The city income tax was 1% (I think) but again it's withheld along with state and federal taxes.

So your point about taxation without representation is - I guess - moot. People always have the option to look for a job somewhere outside the city limits if they don't want to pay taxes to the city.
