In EU countries/regions, every sales and purchase transaction is subject to GST calculations. For more information about recording GST, see Recording GST.

Manually Adjusting GST Amounts in Sales and Purchase Documents

The program automatically calculates the GST using the customer's GST Bus. Posting Group and the item's GST Prod. Posting Group. However, you can also manually enter the GST amounts, if the amount calculated by the program is slightly different to that calculated by your customer or vendor, for example, due to rounding.

To manually enter GST in sales documents

  1. In the Shortcut iconGeneral Ledger Setup window, specify a Max. GST Difference Allowed between the amount calculated by the program and the manual amount.

  2. In the Sales & Receivables Setup window, place a check mark in the Allow GST Difference field.

To adjust GST for a sales document

  1. Open the relevant sales order.

  2. Open the Sales Order Statistics window.

  3. Click the Invoicing FastTab.

    Note
    The total GST amount for the invoice, grouped by GST identifier, is displayed in the lines. You can manually adjust the amount in the GST Amount field on the lines for each GST identifier. When you modify the GST Amount field, the program checks to ensure that you have not changed the GST by more than the amount you have specified as the maximum difference allowed. If the amount is outside the range of the Max. GST Difference Allowed, a warning will be displayed stating the maximum allowed difference. You will be unable to proceed until the amount is adjusted to within the acceptable parameters. Click OK and enter another GST Amount that is within the allowed range. If the GST difference is equal to or lower than the maximum allowed, the GST will be divided proportionally among the document lines that have the same GST identifier.

Manual GST Calculation Using Journals

You can also adjust the GST amounts calculated by the program in general, sales, and purchase journals. It may be necessary to do this when you enter a vendor invoice in your journal and there is a difference between the program's calculated GST amount and the GST amount on the vendor's invoice you have received.

Before you manually enter GST on a general journal

  1. In the Shortcut iconGeneral Ledger Setup window, specify a Max. GST Difference Allowed between the amount calculated by the program and the manual amount.

  2. Place a check mark in the Allow GST Difference field for the relevant journal in the Shortcut iconGeneral Journal Templates window.

Before you manually enter GST on sales and purchase journals

  1. Check the Allow GST Difference field in the Shortcut iconSales & Receivables Setup and Shortcut iconPurchases & Payables Setup windows, respectively.

  2. Once you have completed the setup described above, you can adjust the GST Amount field on the general journal line, or the Bal. GST Amount field on the sales or purchase journal line, to equal the invoice GST amount. The program will check that the difference is not greater than the specified maximum.

    Note
    If the difference is greater, a warning will be displayed stating the maximum allowed difference and you will be unable to proceed until the amount is adjusted accordingly. Click OK and enter another amount that is within the allowed range. If the GST difference is equal to or lower than the maximum allowed, the program will show the difference in the GST Difference field.
