It is very difficult to get tax withholding to align with tax liability in a given year in PL. Since PL is already calculating tax liability, could you add a simple option that sets tax withholding equal to calculated tax liability starting in year X? This would eliminate the messiness of tax refunds and tax payments year to year in PL. A lot of us (in real life, not in PL) likely adjust our salary withholding each year or make estimated tax payments, in order to minimize net tax return payments/refunds each year. Adding this feature in PL would just assume that we would continue that habit and it would eliminate the cash flow “noise” year to year in PL.
