What is the statute of limitations for tax issues in Massachusetts? I looked it up, and it appears that there is an unlimited amount of time that MA can come after you: http://www.mass.gov/dor/individuals/filing-and-payment-infor...

However, using the technique that ChuckMcM described, that limitation would be 6 years. Sounds like we should start filing $0 returns for states we don't reside in anymore..
