May I ask … are the interest from government treasuries TAXABLE?
Yes, unless you purchase them within a Roth IRA. For example, I don't purchase treasuries directly, I purchase a mutual fund of treasuries like PRULX. When I do that in my Roth IRA the treasury dividends are non-taxable (assuming I abide by the Roth IRA rules). I hear that you can buy individual treasuries within your Roth IRA but I've never done so.
But unless you purchase treasuries within a Roth type vehicle, then yes the interest is taxable.
