I've had the pleasure of gaining some understanding of how confusing taxes are when you're an expat. There are specific residency rules for California, the US and the UK - depending on the number of days you work in a certain country you're eligible to pay certain taxes, etc. The bonus is that I get out of doing my taxes for two years! Woo!
I'm heading to London for 3 weeks starting the 13th, and I'm going to get started opening the various bank accounts I'll need. My current bank doesn't have any European branches, so I'll be setting up a US account and a UK account with a bank that does. I will be paid in US$ (pray for a strong dollar!) and will then have to transfer money between accounts whenever I get paid. This should get interesting, with my luck dealing with banks lately. (For those who missed it, when I was in the UK last time, my bank turned off ATM access to all UK ATMs 3 days before I left even though I'd told them I was leaving, and took over a week mailing me a new card. I was able to withdraw cash if I went into a bank branch and asked them to do a cash advance against the credit card portion, but found this out Saturday at 3pm in a small English town where banks didn't open again until Monday morning and had already checked into a B&B that didn't take credit cards. Grrrr.)
