RSU tax return mistakes to avoid
The same handful of errors cost equity holders thousands every filing season.
Double-reporting vest income
Adding the vest value as extra income when it is already inside your W-2 inflates your bill. Reconcile the supplemental statement against Box 1 before filing.
Accepting a zero cost basis
Filing the 1099-B as issued turns already-taxed income into phantom capital gain. Always adjust on Form 8949.
Ignoring the withholding gap
22% withholding plus a 35% bracket equals an April surprise and possibly underpayment penalties. Use the safe-harbour rules to avoid the penalty even if you owe.
