When you can't pay an employee because 'total taxable annual salary' (Jaarloon BT in Dutch) is missing, you can calculate and fill it in yourself.
Go to their profile and fill it out under Pay > Total Taxable annual salary.
A simple formula for on-call and variable-hours employees
Soigné calculates this using the following formula:
Total taxable annual salary = estimated working days per week × 8 hours × hourly wage × 52 × 1.08
Here's how to get each number:
Estimated working days per week: look at the employee's actual schedule over the last 4 to 8 weeks (check their Schedule history) and estimate how many days per week they typically work.
8 hours: Soigné uses a standard 8-hour workday for this calculation, regardless of actual shift length.
Hourly wage: their current gross hourly wage.
× 52: this annualizes the weekly estimate.
× 1.08: this adds the 8% holiday allowance on top.
Worked example
Sanne is an on-call employee earning €14,- per hour. Looking at her recent schedule, she typically works 3 days per week.
3 × 8 = 24 hours per week
24 × €14 = €336 per week
€336 × 52 = €17,472 per year
€17,472 × 1.08 = €18,869.76
Fill in €18,869.76 as the Total taxable annual salary.
This is an estimate, not a promise
The Belastingdienst doesn't expect an exact number here it's used to determine the right tax percentage, not to predict an employee's actual earnings. If hours change structurally later in the year, you can simply update the field again.
Effective from
Don't forget to put the 'effective from' date on the first of the month of which you want to pay your employees. So if you are blocked from paying them in June, put the effective from date on June 1st.
