OMG American Taxes!

Hi!
After having received amazing help with my spousal visa, I now need some help with the minefield that is US taxes!
My husband (USC) arrived here in Apr 2015 and started working in Jun 2015.  He also has a property which he rents out in the US.
I am British and I also work.
Can someone please tell me which forms he needs to fill out, as it's very confusing.  He is not very good at computers, and is only used to filing his taxes for when he worked in America.
We don't have $10,000 in a bank account...(think I saw that as a threshold for something)
I know absolutely nothing about US taxes.

Thank you so much to anyone who can help, or point me in the right direction.

Your husband should be dealing with this. He should be filing "married separately" and filing the same forms he would do in the US. He will declare his UK income and US rental income on his Federal US taxes, so at least a 1040 and Schedule E, and probably just declare the rental income for state tax purposes. Foreign tax credits (form 1116) or FEIE should be applied for the UK wages so there should be little to no US income tax, but the the full US tax would be paid on the rental income. On the UK tax side a foreign tax credit would be taken on the rental income when he files his UK self assessment.

From a UK perspective he needs to be registered for self-assessment - and can decide if he wants to elect to claim the remittance basis or file on the arising basis.

We don't have $10,000 in a bank account...(think I saw that as a threshold for something)

The $10K is the magic amount for FBAR (now FinCen) reporting; this is separate from a US tax return. The requirement kicks in when the aggregate value of all foreign financial accounts that a US citizen either "owns" or has a signature authority is $10K or over. It's not just $10K in a single account, and it's based on the maximum value of each account at any point during the year.

For example, say you have $5K in one account on June 1. You open another account and transfer $4K to the new account, and leave the first account untouched. You start making deposits, and in September (or whenever) the second account has $5001. Even though the first account has only $1K, the maximum value was $5K. So for FBAR, it's $5K + $5001 = $10001 and you have to file. Accounts that you, the UKC have in your name only, and that your husband doesn't have signature authority over, don't count.

FBAR can get complicated, as financial accounts are more than just bank accounts. Your husband needs to be aware of the reporting requirements. FBAR is only filed on-line, and must be done by June 30 (unless they've changed the date for the 2015 filing - I haven't looked).
