15. I'm a residential customer and received my electricity bill on 15 March 2024. Why is the Service Tax charge shown separately as 6% and 8%?
For residential customers receiving bills in March 2024, the Service Tax charge will be prorated based on the number of billing days in February 2024 (6%) and March 2024 (8%).
The following are sample bills for service tax calculation scenarios:

Example 1: Service tax calculation for Transition Month
Tariff: A- Domestic
Billing Period: 13.02.2024 - 13.03.2024 (30 days)
Usage: 648 kWh

Example 2: Electricity Bill Calculation from 1 March 2024 (No Transition Period) with Billing Period 28 Days and above
Tariff: A- Domestic
Billing Period: 03.04.2024 - 03.05.2024 (31 days)
Usage: 730 kWh

Step 1:
Identify usage above 600kWh:
730kWh - 600kWh = 130kWh

Step 2: 
Refer to the 'ST Non-Applicable' column.
Service Tax is calculated based on the current month's usage multiplied by the Service Tax rate.
RM70.98 x 8% = RM5.68

Example 3: Electricity Bill Calculation from 1 March 2024. (No Transition Period) with billing Period Below 28 days.
Tariff: A- Domestic
Billing Period: 25.04.2024 - 20.05.2024 (26 days)
Usage: 302 kWh

By checking the 'ST Applicable' column, Service Tax is applied to the total monthly usage (kWh) since the billing period is below 28 days.
RM71.99 x 8% = RM5.76
