financial express review: Award Claim Notification

I received a letter from financial express stating that I was a winner in the North America Consumer Promotion Draw and was entitled to the sum of US $9968.00. There was an enclosed check supposedly drafted from Altura Credit Union in the amount of $996.80 per WV state regulations, a tax amount of $920.00 would be required before the lump sum winning could be sent to me. The letter was signed by J.J. Sparks, Vice President of Finance. How should I handle this letter?
Thanks
