My business completes a Instalment Activity Statement monthly and BAS every quarter. I don't understand why I am having to pay for the same PAYG tax withheld in both the IAS and then again in the BAS? I have contacted via secure mail over 7 weeks ago with no reply.
Hey @lines09,
Yes, you do still need to lodge both. Your IAS that you lodge and pay monthly is for the instalments towards your business tax return. This is to hopefully avoid you receiving a large debt when you lodge your tax return.
Your BAS that you lodge quarterly would include the GST and the pay as you go withholding (PAGY) that needs to be paid to us. The PAYG withholding is the tax you withhold for your employees its completely different to your monthly IAS.
Hope this helps!!!
