Tax withholding, also known as taxation at source and withholding at source (there are some differences) are, somehow, charged on the source or payer of income and he is authorized to recover the tax by deducting and retaining it when paying the income to its owner. This is very common practice in England and other countries, such as Brazil.
For example, when an invoice of $1000 is paid by a company (customer), the government authorize the company to withhold 10% of the invoice, thus paying to the vendor (who issued the invoice) just $900. The tax is transferred (by the customer) to the tax agency ($100). The vendor can now contact the tax agency to receive full/partial refund on the withheld tax.
How can QuickBooks handle this?
Thanks for your help, Arthur.
