I also hadn't thought about clearing the cache. That could resolve other issues I've had with FX calculations holding after the line has been changed. Never too old to learn something new :-) 100% GST AccountRight Have been using Import Duty 100% tax type for a long time for 100% GST paid to customs and sometimes paid to suppliers when the GST have to be paid in advance of the rest of the invoice. A client is having problems with it halving the value sometimes and adding on if the transaction is changed. Occasionally I have to delete the GST line and reenter it to correct it. I am unsure if the client has been using the wrong tax code and then amending it to cause this problem. This is what it should look like (invoice below, recap journal on top). I've attached a snapshot of the GST report showing what sometimes happens (can't show the accounts I have already corrected the error in the accounts). I can't upload the second image into the text either, it's like it's jinxed! When trying to correct this one, it kept adding more GST on so I had to delete the line and start again. Have found ARL to be like that.. Has anyone else experienced issues with the 100% Import Tax calculating incorrectly, or do you think my client has been changing codes? Solved
