“In this world nothing can be said to be certain, except death and taxes” is an old saying. A variation is:
 
“Taxpayer: A person who resents that death and taxes don’t come in that order.”
 
The modern saying has been cited in print since at least 1944 and was popularized in the newspaper feature “Daffynitions” by Paul H. Gilbert.

The YBQ also quotes “Death and Taxes, they are certain,” from Edward Ward, The Dancing Devils (1724).
