How do I add a percentage to shipping rates?

I would like to add basically my state tax to all shipping rates since when I ship the items I will be paying the local/state tax. How would I include a flat percentage to all shipping charges based on the shipping amount for each order? Thanks!

Bump!!!!!!!!

you can set the shipping to include taxes automatically. have a look though the tutorials for how to do this, it's just a setting in the admin.

The other alternative would of course be to add the tax to the shipping manually when you configured your shipping module

Thanks. Not sure where to look. Basically I just need to include a tax percentage to all shipping prices without the order indicating the shopper was taxed, maybe just a flat fee percentage added based on SHIPPING prices? Anything additional? Thanks!

What shipping methods are you using? :unsure:

The USPS and UPS mods, payment mod is Paypal. Basically I want to make sure that I charge my state and local tax on shipping so that when I go to ship the items I don't lose money. A flat percentage ONLY on the shipping charges would be good also, but I don't know how to do that... I don't want the percentage or "tax" on the items purchased, just the shipping portion...

Edit the two shipping modules and below the line:

          $cost = preg_replace('/[^0-9.]/', '',  $cost);

and add to the $cost your percentage ...

      $cost = preg_replace('/[^0-9.]/', '',  $cost + 10%);

So, if my tax amount is 10% I would code it like above? Thanks.

No ... you need to add the custom code UNDER that line with something like:
$cost = $cost * 1.10;
