What to Reserve From This Check
Why Commission Income Catches Agents Off Guard
A W-2 employee never thinks about tax reserves — their employer withholds taxes from every paycheck automatically. As a 1099 real estate agent, your sponsoring brokerage pays your commission split in full, with nothing withheld. That means the responsibility for setting aside your own tax reserve, and paying it quarterly, falls entirely on you.
The danger isn't the tax itself — it's the timing. A big commission check feels like a windfall the day it lands, but a portion of it was never really yours to spend. Agents who treat every check as 100% spendable income are the ones who scramble every April, or every quarter, to cover a bill they didn't plan for.
What This Calculator Covers
- Self-Employment Tax (15.3%): Covers Social Security and Medicare — the portion a W-2 employer would normally split with you, but which 1099 agents pay in full.
- State Income Tax: Applied using your state's rate, pulled from the same data behind our state-by-state Agent Tax Estimator.
- What it doesn't cover:Federal income tax, which depends on your total household income, filing status, and deductions — not just this one check. That's why many agents round up to a 30% reserve as a safer rule of thumb.
