Example (made-up): a $450,000 sale at 2.5% pays $11,250.00 gross commission. After a 70/30 split that hits your cap, a 6% royalty, a $395 transaction fee and $250 of deal costs, $7,930.00 is yours before tax ($3,320.00 went to the split, royalty, fees and costs). Set aside $2,224.47 for 2026 self-employment and federal tax plus 5% state, due with the Form 1040-ES payment of January 15, 2027. You can spend $5,705.53: $5,544.47 of the check is gone before it reaches you.

Type your own deal: listing or buyer side, referral out, your split and the company dollar you still owe before you cap, royalty, fees. The tax set-aside is your whole-year 2026 tax with this closing minus without it, using the IRS 2026 brackets, the $184,500 social security base and the 20% QBI deduction.

Pro: your whole year of closings

A calculation and record tool for your own deals, not tax or legal advice. Tax figures use the IRS 2026 Form 1040-ES (rev. Feb 12, 2026: tax rate schedules, standard deduction, $184,500 social security base, 92.35% and the payment dates April 15, June 15, September 15, 2026 and January 15, 2027; irs.gov, read 2026-11-13) and the 2026 QBI thresholds of Rev. Proc. 2025-32 ($201,750; $403,500 joint). The QBI estimate assumes you pay no W-2 wages; the 0.9% Additional Medicare Tax is counted above $200,000 ($250,000 joint) of self-employment earnings. 2027 closings use the same date rule: April 15, June 15, September 15, 2027 and January 18, 2028. Splits, caps and fees are yours: take them from your brokerage agreement.
