The best way to proceed would be to file your spouse separately in Massachusetts. To do this, you would need to prepare a separate federal return for her as a single filer. After you complete her state return for Massachusetts, you can file it. Then, go back to the federal return and switch the filing status to married-joint, enter your information and complete the federal and New Hamshire returns and file them.
