Why your invoice amount and your bank deposit don't match
It can be surprising the first time a client pays you less than the amount on your invoice. That gap is usually the withheld tax, not a billing mistake -- the client is required to hold back a portion and send it to the tax authority on your behalf, then hand you a statement showing exactly how much was withheld.
This is general information, not tax advice
Exact withholding rates, thresholds, and filing deadlines vary significantly by country and even by type of income. Treat this as a general explanation of the mechanism, and confirm the specific rules that apply to you with your local tax authority or a qualified tax professional.
Frequently Asked Questions
Is the withheld amount my final tax, or just a prepayment?
In most systems it is a prepayment, not a final settlement. Your actual tax owed is calculated when you file your annual return, and the withheld amount is credited against that final figure.
What if a client doesn't give me a withholding statement?
You can generally request one directly from the client, since they are typically required to issue it. If they still don't provide it, your tax authority's online portal may show a record of tax withheld on your behalf that you can use instead.
