Charge additional tax on a per product basis

[fourmat]

Hi Folks,

I have a client who sells tires, and other products. We have run into a situation where we need to charge a disposal tax on just the tires. I have thought about this and researched, but, I have not been able to find any way to charge tax on a per product basis.

Does anyone have a way to possibly make this happen?

The only way that I can think of is to create an attribute that has a 2% charge in it, and make that the default and only option, so it is essentially mandatory. The problem I run into with this, is if I don't need to charge the disposal tax for tires that get shipped out of the state, making it zone dependent.

Thoughts, suggestions?

Attribute was my first thought ... but ...

If it is zone dependant then you can only add it in the checkout ... as this is the first point when you know where your shopper is from.

Perhaps a hack of the zone based shipping module that looks for certain products - you could even try and use the Extra Product Field (hidden in catalog) to load the required field ...

Yep, Zone Table sounds like the way to go...
In psuedo-code:
If zone_id = '1' and category_id='7'
(where 1 = local State & 7 represents all tyres, probably need a series of categories)
then handling_charge = handling_charge + eco_disposal

Would this be added as a new order total module? I also have a MultiGeozone/MultiRate shipping installed that might make a for a more flexible system. I'm just now sure how to go about converting a "shipping module" over to a "tax" module. I have done some modifications of the checkout and order total calculation stream by adding a Local Tax by Zip Code mod, but that was just following instructions. Where would the first insertion point be for this in the checkout process?

If you have installed a "Local Tax by Zip Code mod" then I would start there. I am sure it would be easier to make a copy of this and then simply add the if product=x to the 2nd zip code tax ...

Ie. Simply have a tax which is based on Zip Code and Product Id.

Do you have an URL for the mod?

I think I have V1.1a installed. I hadn't thought about adding on to that mod. Now need to figure out how to make the individual tax rate calculate on a per product basis, as right now, everything is on a per order basis.

To start I could add an extra field into categories.php to handle a secondary tax amount (like 2%), and add a effective tax zone pick box? From there I'm a little fuzzy on where the logic needs to be added to cycle through all of the products in the cart to tack on the extra amount. Where does the tax class get inserted?

Rather than add more fields into categories.php, would it be possible to create a new tax class to handle this? Something like Non-Taxable, Taxable, Taxable+Disposal? Those seem to be dependent on product rather than a complete order...

Sounds like a plan... would need to tie in with State/Zip Code.

I do believe that creating a new tax class will work for this situation. If the disposal tax is applicable for just the state as a whole, and if the state tax is 5%, and the disposal tax is 2%, then I just need to create a new tax class with a 7% tax rate with the name State Tax + Disposal Tax, and apply that to each relevant product. This should be applied in lieu of the standard state tax, which should be applied to other products. I don't believe that the disposal tax is related to a locality by zip code, so there isn't a need to have zip/county tax related to the product level.

Thanks for helping me through this mental exercise...
