mtbc | US taxes

I have now drafted our 2015 income tax return for the IRS. There were a few small changes for this year:

Because of the refund that (again with the help of my Congressional Representative) I had finally obtained from the IRS I had to include on Schedule B the interest they'd paid me.

I appeared to have earned less in 2015 than in 2014 which probably means that the pound weakened against the dollar. For converting my various GBP amounts to USD I use the monthly averages from the Federal Reserve's G.5 data.

I didn't exclude my whole University of Dundee salary as foreign earned income because I could be considered to have earned a small portion of it while in the US on business: I had attended and presented at the BioImage Informatics conference at NIST.

I developed more confusion about my pre-tax payslip adjustments in the University of Dundee's calculation of my total pay from my basic pay: for instance, as I should count the extra income they paid me as arrears for a backdated raise, does that mean I don't have to count the money they deduct for my staff parking pass and some kind of pensions adjustment?

At least my UK taxes are easy at the moment. My most awkward year was when I was receiving non-PAYE employment income from a UK source, consulting income from the US, and was a director of a limited company, and even that wasn't too bad.
