Hi lesleyjones
Actually this might be one for the ATO rather than your accountant. MYOB is calculating the correct amount according to the ATO formula provided to developers (NAT 3539 for 1 July 2023):
| Where employee has claimed the tax free threshold |
| in Tax file number declaration with or without leave loading |
| Scale 2 | |
| WITH STSL Debt |
| Weekly earnings | | |
| (x) less than | | |
| $ | a | b |
| 359 | 0.0000 | 0.0000 |
| 438 | 0.1900 | 68.3462 |
| 548 | 0.2900 | 112.1942 |
| 721 | 0.2100 | 68.3465 |
| 865 | 0.2190 | 74.8369 |
| 930 | 0.3477 | 186.2119 |
| 1073 | 0.3577 | 186.2119 |
| 1138 | 0.3677 | 186.2119 |
| 1206 | 0.3727 | 186.2119 |
| 1278 | 0.3777 | 186.2119 |
| 1282 | 0.3827 | 186.2119 |
2394 /2 = (1197 * .3677)-186.2219 = 253.90 *2 = 508 (rounded)
1900/2 = (950 * .3477)-186.2219 = 144.09 * 2 = 288 (rounded)
It is a mystery the ATO's pdf tax tables give $520 and $308 respectively when you use the NAT 1006 + NAT 2185. I would suggest the formulas provided to the developers contained an error.
