What's wrong of having one <form> that wraps everything up?

<form id="personal-data" class="form-horizontal" method="POST" action="#">

<div class="tabbable">
  <ul class="nav nav-tabs">
    <li class="active">
      <a href="#1" data-toggle="tab">Tab1</a>
    </li>
    <li>
      <a href="#2" data-toggle="tab">Tab2</a>
    </li>            
  </ul>
  <div class="tab-content">
    <div class="tab-pane" id="1">      
      ...
    </div>
    <div class="tab-pane" id="2">
      <!-- form controls to be continued here -->
      <p>Howdy, I'm in Section 2.</p>
    </div>            
  </div>
</div>

</form>

are you submitting tab by tab or once on the last tab?

if one-by-one (for exemple, validation), simply use $.post to send data back and forward on-the-fly (in other words, make ajax calls).
