@Warlock  so these people that are so called specialists are not understanding you or me- regardless of the rate in qbo- which MINE is set to the correct one- it is not calculating correctly so pointless- I actually have an open ticket for them to look in my client's books because they too are a small company and having to make up the difference since it is not legal to go back and pull monies from the employee after the paycheck has processed for the WA PMFL.   I suggest you make a new payroll deduction to use as your PMFL deduction and create your own spreadsheet to calculate l the correct amount that should be pulled out- this is my work around. Which means you will then have to hand enter the amount for each employee and each payroll. Takes a little bit more work at payroll, but will save you having to make up the difference.   You can get the exact math from the WA pmfl website and they have a converter- because ultimately- quickbooks can tell you all they want that they are correct- but the State of WA will tell you or any state using a payroll based PMFL- or any payroll quarterly report you file- ultimately it is up to the business to make sure the data given is correct and if audited and they find your payroll system- qb is miscalculating- they will still say you were ultimately responsible for paying the correct amount.
