On the bottom third of the home page is the above referenced text which is also hyperlinked to the /Shipping-and-Charges/ page.
How does one alter the wording of this string as we do not use the wording VAT?
NB: there is a second refernce that I just noted that is lower down the page. My question also applies to this and all other references if there is no ‘Global’ solution.
Thanks

Hi Don_in_OZ,
I reckon you’re an Aussie, right? (As I am admin, I can see your IP 
)
On your server, you will find a file on this location: /out/azure/en/lang.php (assumed you are using version 4.5.0 with ‘azure’ theme). Any change you do there shall go to cust_lang.php so lang.php can be overwritten with the next update. The shop will firstly search for the changed language constant in cust_lang.php; if it doesn’t find anything there, it uses lang.php in the same folder.
This behaviour will be changed a bit with the next patch: there’ll be a general lang file, a lang file for each theme and a custom lang file.
I am just wondering what you guys would use for “VAT”, just “tax”? Also, I have no idea how the tax handling is used over there: the European way (show products incl. tax) or the Ami way (show products excluding tax and add them in the basket).
Would be great if you could contribute your finished lang files for azure resp. version 4.5.1 to the community

Hi Marco
You guessed it. I am an Australian (as well as a Canadian) living in Australia for the last 30 years, however as I lived in Germany for 13 years, am think of myself as part Deutscher too!
I would be happy to post my files that pertain to Australian adaptations of the OXID files if you can coach me along the way as you are doing now along with the help of some of your other senior contributors and or moderators.
Australian law requires that all ‘RETAIL’ pricing be inclusive of GST (an anagram for Goods & Services Tax). This tax might be variable but since its introduction is set at 10% on the retail price. That is $100 plus 10% = $110 including GST. We do not show GST separately in general as it is a known item and unavoidable.
There are some items which are free of GST so retailers will quite often refer to items as either ‘taxable’ or ‘GST free’. Both methodologies are correct. All invoices, bills of sale, cash receipts and similar are required to show the words “TAX INVOICE” where there is a collection of GST. Anyone who issues such “TAX INVOICES” must be registered for GST and is required also to post their Australian Business Number (ABN) which is generally an 11 digit number. The protocol for displaying this number is for the number to follow immediately after the official company name. For example: ABC Business Pty Ltd - ABN 12 345 678 910 Note the separation between the numbers is deliberate and they should be formatted in this way.
A refund is in effective the same document but done in a minus format. It is still a GST or TAX INVOICE but instead of +$100.00 it refers to -$100.00 indicating a reversal of the sale and GST chargeable.
These conventions are used for retail or end user scenarios. There are different conventions applied for wholesalers who generally show the tax free amount, the GST being Charged and then the combined amount inclusive of GST. A story for a different chapter. 
If you wish to delve into Australian Taxation further, there is a GST overview section on the Australian Government’s Taxation Office website which is well organised and descriptive. http://www.ato.gov.au/businesses/content.aspx?doc=/content/57709.htm
To answer your specific Questions:
We would use GST as a substitute for reference to tax but use the anagram in conjunction with the words: “GST included in Total” and or “* GST Free item” where there was a single item that did not include GST, with the assumption being therefore that all items barring the exception include GST.
The Australian way of showing tax is closer to the European way and definitely not similar to the North American way. Having said this, closer is not close enough unfortunately and some modifications to the current 4.5 template would be required to conform to Australian Taxation laws.
I am currently using version 4.5.x

I also live in Australia and also wondering about “tax” but until my friend recommend me this tax liens investment it helps me a lot to know about it.
Thank you
