Tax: Following on from the previous entry, I’ve had a stroke of luck. It turns out that I did indeed quality as a US resident for tax purposes, and therefore could use Turbotax.
20 minutes later, both state and federal forms were e-filed with the very minimum of fuss — computers and the net illustrating their worth as labour-saving devices quite nicely. ;)
(Oh — also — a PSA for Google’s benefit: I’m pretty sure that form 6251 had incorrect instructions. It claims that the items it refers to in form 1040, can also be referred to in form 1040NR by the same numbers. In fact, parts of 1040NR are radically different in numbering than 1040. It’s a bug in the form!)
