To anyone filing "Married Filing Joint" - be very aware that you need to report you total INTERNATIONAL income. If your spouse is making any money this need to be reflected on your tax return. You can re-claim any international taxes paid. "Married Filing Joint" almost always results in less taxes paid. So if possible - do the extra work and file this way.
