Why are my model properties null when trying to POST?

So I'm trying to create a login page and I've created a form that posts to a action inside the controller.

This is what the controller looks like, very simple, just for testing purposes.

public ActionResult Verify(User account)
{
    var s = account;
    if (db.Users.Any(o => o.Username == ""))
    {
        // Match!
    }
    return Redirect("https://google.se");
}

And here is the HTML

<form id="form1" method="post" action="Verify">
    <!-- Input and Submit elements -->
    <div class="form-group">
        <input type="email" class="form-control form-control-user" id="Username" name="Username" aria-describedby="emailHelp" placeholder="Enter Email Address...">
    </div>
    <div class="form-group">
        <input type="password" class="form-control form-control-user" name="PasswordHash" placeholder="Password">
    </div>
    <a href="Verify" type="submit" class="btn btn-primary btn-user btn-block" >
        Login
    </a>
    <hr>
</form>

When I click Login it does invoke the Verify action, however the parameter I'm passing in account all the properties are null and I'm not sure why.

You are not really submitting the form, unless some javascript event does that for you.

Try changing 

<a href="Verify" type="submit" class="btn btn-primary btn-user btn-block" >
    Login
</a>

to a submit button instead

<button type="submit" class="btn btn-primary btn-user btn-block" >
     Login
</button>

When you use a link then you are making a GET request which wont post your form data to the controller, in chrome you can see that for yourself in developer tools/network, open that and then click Login, this should result in the Verify request showing up in the list of requests.

If you really want to use a link and not a submit button, then you can add a bit of javascript to submit your form, either by adding a event handler or submitting the form directly from the link's onClick method.

<a href="Verify" onclick="document.getElementById('form1').submit();" class="btn btn-primary btn-user btn-block" >
    Login
</a>
