Do taxes have to be uptodate in the US to file for US spouse visa?

We are fixing to go through the process of moving back to the US and need to apply for my British husband's visa. I have picked up on a lot of information I wasn't aware of through this site but haven't seen anything mentioned regarding this. As I am the petitionary I don't want this to be the thing that messes it all up. I had just thought I would use my tax advisor in the US that I have used in the past when we moved.
Any information greatly appreciated. I don't think I have made $85k in the last 4 years combined due to maternity leave.

Thanks Marli

Nothing wrong with using an advisor stateside.

Just make sure they understand how to report child benefit, how to file foreign trust returns for a UK child trust fund and are themselves comfortable with the level of penalties for deliquent FBARs as well of course as the slightly weird UK tax year-end.

If you have ISAs or UK pension savings or indeed a UK mortgage they will need to advise you on related US tax reportiing.

In essence being tax 'delinquent' in not a good place to be right now as sadly international tax delinquency is exactly where the IRS are focusing huge amounts of effort today.
