Why Payroll taxes not deducted correctly in QBO Payroll System???
Hi, I have been using QBO payroll function to run semi-monthly payroll for two companies since April 2022. I always check payroll deduction (CPP, EI, Tax) amount with the payroll deduction online calculator (PDOC) of CRA website. For April month, the tax deduction on QBO is same as on PDOC.
But when I do the May1-15 period payroll, I find that the tax deduction on QBO is different from PDOC, QBO deduct more CPP and Less tax than PDOC. This make a big difference in net pay amount. I checked all the possible factors such as pay period frequency, Federal and provincial amount, Max CPP reached etc. Everything is right, so I couldn't find the cause... I can only manually correct all employee's CPP and tax amount on the payroll of May 15th based on PDOC's calculation, this took me a lot of time
Also, I haven't changed any payroll settings since April, so I wonder why the April payroll deduction on QBO is correct and May's are not. And the two companies have same the issue... It seems a bug of QBO payroll tax table.....
Anyone have the some issue in May when running payroll? Any solution except manual correction?
Below is an example, QBO and PDOC screenshot for an BC employee, Semi-monthly, gross pay $1664
QBO PDOC
Gross pay $ 1664 Gross pay $1664
Income tax $ 179.30 Income tax $189.30
EI $26.29 EI $26.29
CPP $136.40 CPP $86.54
Net pay$1322.01 Net Pay $1361.87

Thanks
