Common questions

Frequently asked questions

Does this file a W-4 for me?

No. It only estimates a planning adjustment. Any actual withholding change should be handled through payroll and reviewed carefully.

What does a negative suggested change mean?

A negative result means the current projection may be above the target, so less withholding may be needed if the assumptions are accurate.

Why can the real refund differ?

Credits, deductions, income changes, filing status, payroll timing, and tax law details can all change the final refund or amount owed.
