Changing Tax and Shipping calculations

Hi I tried to suss this out myself a few months ago and didn't get anywhere. Back on the project now and hoping maybe I can get some advice on here. In checkout, order emails, and invoices, I need to change how shipping and tax are handled. I need to show tax (VAT) figure including tax applied to shipping. Is there a simple thing I can do to replicate something like this (this is from a Amazon UK order email I had on me)

• Items listed (price inc tax) £7.00
• Item Subtotal: £5.83
• Delivery & Handling: £3.33
• Total Before VAT: £9.16
• VAT: £1.83

Order Total: £10.99

I've sussed out using the language screen to change the names to anything I want, I'm more concerned in getting to show the summary in the order and calculations done above. Especially having the subtotal being before tax, and having the shipping before tax, and all tax totaled (inc shipping) on one line. I gather I might need to change templates but a guidance of the code would be appreciated. Cheers

Thanks Nicolas, that helps and gives me some options to play with.

Just in case you're taking feature requests/wishlists for future versions - Guessing would be over the top if this doesn't get asked a lot by other users, but for me would be a nifty feature if within configuration a user could optionally choose an advanced 'custom order layout' option to alternatively build up their layout of the checkout/orders/invoices in a similar way you can currently build the 'checkout workflow' by dropping elements into a simple certain linear order. Eg have various elements you can drop in and get used uniformly throughout ALL order breakdowns, with elements such as:

• Products listed inc tax
• Products listed w/o tax
• subtotal inc tax
• subtotal w/o tax
• shipping inc tax
• shipping w/o tax
• Tax (of subtotal)
• Tax (of shipping)
• Tax (of grand total)
• Grand Total
• Coupons,etc

I suppose even a series of dropdown boxes listing the elements instead of the drag and drop method would do.

Hello,
I just added it on our TODO list .

oh excellent. Hope it makes it through. cheers

Any advance on this TO DO?

Has this item made it to the top of the ToDo list yet?

What I need is to make the tax and total lines in the email notifications match the HikaMarket Control Panel Invoice
where you have:
Subtotal
Sales Tax
Shipping
Total

Instead of
Subtotal
Shipping
TOTAL without Sales Tax
TOTAL with Sales Tax

I know I can change the two "Total" lines to subtotal and Total, but how can I insert just a Tax line?
