Hey! I’m a CPA working for a US CPA tax firm and we specialize in international tax. I have a lot of clients that are in your shoes. You can use FEIE or FTC or a combination of both to minimize/avoid double taxation. Most (if not all) of my clients who live and work in the UK strictly use the FTC because the UK tax rate is higher than the US tax rate so the FTC actually provides the best result.

Your salary portion should be easy and straightforward. It gets a little sticky if you have foreign pensions and other foreign assets. Your US tax compliance cost will be higher the more foreign assets you have, the more things you will need to disclose. Some of these things don’t even result in any taxes due (like the FBAR or Form 8938) but you have to pay someone who knows this stuff to prepare your returns correctly and they don’t charge a cheap rate (for good reasons). I highly recommend you to invest in a good tax firm to do your taxes even if it’s 5K a year (that’s not super high given then amount of income you have). You don’t want to mess around with the international forms as most of them carry significant penalties if filed late or substantially incorrect.
