Keith,
I'm not trying to make light of your idea's. I try to come at things from the other sides perspective. The taxable event occurs quite simply when you deposit a paycheck into a bank account without the proper verbiage. When you follow what the bank recommends they use your paycheck as an asset and credit your account with "bank credit" that is derived from "Fed Credit". The check then shifts "bank/Fed credit" from your employer's bank to your bank via the settlement of accounts performed at the Federal Reserve through each banks individual reserve account. When you restrict your endorsement to demand money issued directly from the US treasury that throws an extra step into their process.

Normally: Bank A owes Bank B $1000, Bank B owes Bank A $1500. The net effect is $500 of credit is transferred to Bank A's reserve account from Bank B's reserve account.

LMUS is demanded: Bank A has a check (from Bank B) where $1000 of LMUS is demanded. The Fed transfers $1000 of LMUS (coin) to Bank A, then deducts $1000 from Bank B's reserve account. The Fed then needs to replenish it's LMUS supply and orders $1000 of coin from the US Mint, it then credits the Treasury with $1000.

This is logically how I see it working. Again the taxable event occurs at the bank when you have an incoming transfer of money substitutes (bank credit). However when you invoke a demand for money properly created by the Treasury you are using the money properly authorized by the Constitution (coinage clause 1:8:5). Anything other then that CAN be taxed as an excise (1869: Veazie Bank v. Fenno, 75 U.S. 533).

I hope this makes sense to you. The "event" is not when filing a return form. That is the part where you try to recover $$ that were not taxable in the first place. You need to restrict your endorsements on your checks AND MAKE COPIES! As David said.
