We have extremely uneven income. How do we fill out the new federal withholding form if we don't know what we will earn for the year? Some paychecks are $1800 gross. Some are over $12,000 gross which includes Permanent Change of Station taxable wages. Then 3 months with no wages at all unless there is a wildland fire, which could be another $6000... I have tried several online calculators but haven't found one that works for our situation.
