Looking for Someone Who Knows Taxes

[diadromous mermaid 36]

I've already prepped my federal and state taxes (I owe on both; just a few bucks to the state but several hundred to the IRS, but let's not talk about that!). The problem is my local taxes. I have an extremely complicated local tax situation, as you'll see:

1.) I started off the year living, let's say, in City A and working in City B. City A's local income tax is 2.85% and City B's is 1.75%. The firm I worked for was deducting local taxes for City B, not City A where I actually lived, at the City B rate.

2.) In March, I received paychecks from my current job in City C, with an income tax rate of 3.4%, while still living in City A. However, I've only just now discovered that my job in City C has only been deducting at 1% for my local taxes, even though the job is located in City C at 3.4%.

3.) From April through the end of September, I lived and worked in City C, all the while having only 1% deducted from my taxes. I also acquired, in June, a second job in City C. I forget what rate they withheld at for my local taxes, but I don't think it was enough.

4.) Finally, in October, I moved to City D, whose local tax rate is only 1%. I continued to work both jobs in City C.

To recap:

City A: 2.85%, where I lived but did not work from January-March.

City B: 1.75%, where I worked but did not live from January-February.

City C: 3.4%, where I lived and worked from April-September.

City D: 1&, where I lived but did not work from October-December.

So:

1.) Who do I file taxes for? My gut says only cities A, C, and D.

2.) Which income do I report to each? Only the income I made while I was living there?

3.) How do I figure out how much tax I owe to each and how much was actually deducted while I lived in each city?

Thanks to anyone who can sort this out.

I'm under the impression that local tax is determined on the city in which you live. So if you lived in a city that requires 1% tax, but worked in a city where they deducted 2% you'd have an overpayment. A,C, D?
