Calculation of Income Withholding Tax

To calculate the tax amount to be withheld, we use Canada Revenue Agency's (CRA) formula, plus the information from the last Federal and Provincial Personal Tax Credits Return (TD1) and Request for Additional Income Tax (if applicable) forms we have received from you.

If you need to report any changes to us, these forms are available from CRA or ATRF (“Additional Tax”).

Because income tax regulations and personal circumstances vary, ATRF does not provide taxation counseling. Please contact your tax advisor or the nearest District Taxation Office of CRA to obtain any tax law interpretations.
