Removing padding/margin from I.E

At my site https://www.wahow.org there is my header area which changes to the category when viewing any post. In firefox this changes with no problems, however in I.E a white space appears below the header. For instance take a look at https://www.wahow.org/business-finance/how-to-build-an-adsense-empire/57/.

I know it’s the H1 tag that is causing this because it doesn’t happen if I remove it. The CSS is as follows:

#header h1{
font-size: 60px;
font-family: Arial, Helvetica, sans-serif;
font-weight: 100;
margin: 0;
text-decoration: none;
padding: 55px 0 0 80px;
}

Is there any alterations I can make so that it does not produce a white space below the header in I.E?

Thanks for any help.
