In USA & Australia, businesses are typically required to report and remit taxes on sales. In the USA, this is often referred to as sales tax, while in Australia, it is known as the Goods and Services Tax (GST). Reporting involves calculating the tax owed based on sales transactions and submitting periodic returns to the relevant tax authorities.

Businesses in both countries are responsible for withholding and remitting taxes from employee wages. This includes federal income tax, state income tax (where applicable), Social Security tax, and Medicare tax in the USA, and PAYG withholding in Australia. Employers must accurately calculate and withhold these taxes from employee paychecks and then remit them to the appropriate tax authorities.

Both the USA and Australia require certain taxpayers, including self-employed individuals and businesses with income not subject to withholding, to make estimated tax payments throughout the year. These payments are based on anticipated income and are meant to cover tax liabilities to avoid underpayment penalties. In the USA, this is done through quarterly estimated tax payments, while in Australia, it is known as PAYG instalments.
