State tax filing

IMO, this is the bottom line -

 

Nobody really knows, unless:

1) they are a lawyer (and even then, different lawyers could have different opinions)

2) they are a CPA (and even then, different CPAs could have different opinions)

3) they work for a state's tax dept (though not all reps will have been trained equally)

4) they are a taxpayer who has done it wrong in the past and has been audited by their state for it

 

So basically, flip a coin this year, especially if you don't have huge amounts of interest from AMD, and don't buy any treasuries notes/bonds on the secondary market for next tax year. Plenty of zero-coupon treasury bills to be bought with the same interest but without the tax hassle. This is my plan.
