You hate how much you pay in federal income tax. Who would you contact to share your concerns - your House Representative or Senator? Which one has the power to propose new
tax laws?

House Representative.

Explanation:

The Constitution of US states that all bills and proposes for tax and revenue shall originate only in the House of the Representative. Therefore, a member of House of Representative would be much better to share your concerns with because they could draft a bill in your favor.

On the other hand, the Senate/Senators have the power to concur or make certain amendments in the bills introduced in the Lower House. However, they cannot introduce or propose new tax laws in the house.
