RSU tax calculator

RSU vest price does not match payroll or your broker: which number matters?

Different RSU prices can reflect plan-defined FMV, timing, rounding, or net-share displays — reconcile the documents before changing wages or basis.

Your pay stub, vest confirmation, and brokerage lot screen show different prices for the same RSU vest, and you need to know whether the difference is normal or a wage-reporting error.

In plain terms

Start with the employer plan's stated fair-market-value method, not the sale price or whichever screen has the most decimals. An employer may use the closing price, an average, or another price defined by the plan or payroll policy, so there is no universal -price rule. The value payroll actually treated as wages controls the unless payroll corrects it; the confirmation, pay stub, plan terms, and lot history together support the basis you use for shares received.

Gather before you start

  • confirmation showing , gross shares, , and tax shares.
  • Pay stub for the pay period with equity wages and .
  • Broker lot or acquisition-detail export, not only the portfolio screen.
  • Employer stock-plan document or policy for settlements.
  • Trade confirmation if shares were sold to cover or sold immediately.

How the tax works

A stock price is a stream of trades, not one fixed number for an entire day. An employer plan may define as the exchange close, an average of high and low, an average over a stated period, or another consistently applied figure. The plan or payroll policy therefore matters more than a generic market-price lookup.

The , delivery date, payroll posting date, and broker acquisition timestamp may not be identical. A multinational employer can also display timestamps in local time, exchange time, or UTC, making one economic event appear on adjacent calendar dates. Those timing differences can select different market observations even when every system is functioning as designed.

Each system may display a different layer of the transaction. Payroll may show total taxable value rounded to cents, the confirmation may show per share to several decimals, and the broker may show per-share basis allocated across only the deposited lots. Dividing a rounded total by a rounded quantity can create a small apparent price mismatch.

Gross shares, shares withheld for taxes, shares sold to cover, and net shares deposited must not be mixed in one comparison. Wage income is generally computed from the full taxable quantity under the employer's settlement method, while the broker screen may show only shares that reached the account or separate lots for shares sold and retained. A price is a market execution price, not automatically the plan's .

For filing records, the reports the wage amount payroll recognized, while basis must prevent that wage value from being taxed again when the shares are sold. A confirmation that states the plan , a pay stub that shows the wage inclusion, and broker lot records form the strongest reconciliation trail. A material unexplained difference may require payroll to correct wages and may also require a corresponding basis adjustment rather than silently choosing the broker's number.

What to check on your end

  • Read the plan's exact definition and identify the market, date, and price convention it requires.
  • Match , release or delivery date, payroll date, and broker acquisition timestamp, including displayed time zone.
  • Recalculate stated per share times gross taxable shares before rounding, then compare with the equity wage line.
  • Separate gross shares from tax-withheld, , and net deposited quantities.
  • Compare broker acquisition value with the supplemental lot-detail export; a portfolio screen may use a display value instead of tax basis.
  • Compare any sale execution price and fees separately; do not use sale proceeds as proof of .
  • Measure the dollar effect on taxable wages and basis, and ask payroll to explain any material residual rather than only a few cents of rounding.

Using the same-day sale price as the required vest FMV

The sale may execute seconds or hours after the valuation point and can include several fills. Replacing payroll's plan-defined with the sale price can create a false wage discrepancy and an incorrect basis adjustment.

What to pull from your files

  • Plan or award terms: definition, valuation date, and settlement timing.
  • confirmation: gross quantity, tax quantity, net quantity, and precision.
  • Pay stub: equity wages, federal and state wages, FICA wages, and year-to-date totals.
  • Broker supplemental statement: acquisition date, lot quantity, adjusted basis, and any sold-to-cover lot.
  • Trade confirmation: execution time, fills, gross proceeds, and fees.

Closing-price FMV, rounded payroll total, and a later sale

Illustration only, not your tax situation.

Nadia's plan says is the exchange closing price on the . Her confirmation shows 240 gross shares at $51.2375, while payroll displays $12,297.00 of equity wages after its stated rounding process. Sixty-five shares were sold for taxes, 175 reached the broker, and the broker's portfolio screen displays $51.31 as the acquisition price. A trade confirmation shows the tax sale filled at $51.44 after the close. Nadia first asks the plan administrator for the official closing-price calculation and the broker for supplemental lot detail. If the plan calculation reconciles to payroll within rounding, she keeps those records and does not substitute the $51.44 sale price. If payroll used the wrong date and the resulting wage difference is material, she asks payroll to correct the wage record and then makes sure the basis record follows the corrected wage value.

Questions people ask

Does the broker acquisition price control my W-2 wages?
No. The employer's payroll record determines what is reported as wages unless the employer corrects it. The broker record is still important evidence for sale reporting and may need reconciliation to the wage amount.
How much difference can rounding explain?
Recompute using the unrounded per-share and gross taxable quantity if available. Pennies or a small residual can arise from precision and allocation, but the acceptable amount depends on quantity and the documented calculation rather than a universal tolerance.
Why does my lot screen show only net shares?
Shares withheld or sold for taxes may never appear in the retained lot view. Use transaction history and supplemental detail to account for gross, tax, sold, and deposited shares.
Should I change basis to match a corrected W-2?
A corrected wage amount can change the amount already taxed at , so basis records should be reconciled to that correction. Keep the W-2c and payroll calculation with the lot records, and use the appropriate Form 8949 adjustment if the broker does not update its statement.

When a CPA is worth it

  • Payroll used a date or method that conflicts with the written plan and the wage difference is material.
  • A or W-2c wage change cannot be reconciled to basis for shares already sold.
  • The spans countries, states, currencies, or exchange time zones and different wage amounts were sourced.
  • Broker records omit lots or duplicate a sold-to-cover transaction after payroll confirms its calculation.
