Filing usa tax return

We moved to the UK in October 2014, and are moving back to the usa in a couple of weeks. I am filing our tax return via a website and I don't know what to do for address. Because we both worked up until oct 2014 and we paid taxes it is pretty straight forward, but the problem is the address. We are moving in with family at the end of the month so can I just put there address on my tax return? I noticed our refund is also a little more if I put usa address, so should we just wait to file? Would I have to put any information regarding our short stay in the UK? We did work in UK during our stay but neither made much money, and we do have bank accounts in UK but that's it. No property, no cars, so that is quite simple.

Generally, the address you would use is your address at the point of filing a return. If you are moving back in a couple of weeks, why not wait and use your US address, even if temporary. You can always file a change of address form when you get a permanent US address.

Your UK income is reportable of course.

Did you pay UK tax on your UK earnings?

You may have moving expenses to deduct, you may owe a healthcare penalty if you did not have US healthcare in the last few months of 2014. You might have foreign tax credits to claim; you might have remained State resident so owe State tax on UK source income. You might also have to file an FBAR. 

Thanks for the response. It seems a little more complicated. I didn't know I have to file my UK wages on my us tax return, I thought that all I had to do was file a UK tax return aswell. I didn't pay any taxes just national insurance because I didn't make much. I didn't have healthcare in the last few months and put that in my taxes. I paid quite a lot of taxes both federal and state with my income in usa last year. Not sure
About foreign crdits as I read you have to be out of country a year and I didn't pay tax in UK because I only made probably 1200 during those few months. What is fbar? This seems very confusing now, I didn't realise it was such a hassle. How do I report my UK income on my taxes without a w-2?

You total up what you made for the calendar year and report it. The US taxes citizens on worldwide income, so any money you made in any country.

can I just report it in other income and just write the amount and then say foreign income. I use a website called taxslayer and the only foreign income says exclusion, and this is for like US companies based abroad. Or does it have to be more detailed with employer details, etc... I was also looking at the FBAR. I have never had 10000 dollars in my bank. In the UK I have never had more than a 1000 pounds in my bank, so I am not sure if I need to report bank account details.

What was your residency status in the UK? What was NI deducted but no UK PAYE tax?

You must include all your income on your 1040 and you can use the "Foreign Earned Income Exclusion" if you've been out of the US for long enough (looks like you haven't) or take a credit for foreign taxes you paid.

I was born in the UK, so I have dual citizenship. We moved in October and I paid NI straight away but no taxes. I was told it was because they don't tax you under 8000 or so a year. During Oct-Dec I made about 1200 pounds, and my wife made about 800 pounds. Because I didn't pay tax in Uk I cant get foreign credit, and when I put the info for my UK wages in the Exclusion it asks for US address of company. As soon as I figure out where to put the money I earned in Uk I will add it in. I went through all the income and I cant seem to find a place to put it. Unless I just put it under other income and it says how much $ __________ and what is it ____ and I am not sure if that is acceptable.

You haven't been out of the US long enough to use the FEIE and if there is no UK tax due you can't take a tax credit, so you just have to pay US tax on your UK earnings.

As it's "wages" you enter it on the line 7 of the 1040 with your US "wages". You can complete a 4852 if you want a way to document your UK wages.

thanks for the info. I have only used taxslayer and efiled my taxes so I have no idea what line 7 of 1040 or form 4852 is. Can I e-file and then send the form 4852 separately?

No - all forms must be filed at the same time, whether an e-file or paper file.
