Tax Reserve for Variable Income
A tax reserve separates money that may belong to federal, state, or local tax authorities from money available to spend.
Choose a temporary reserve rate
Until you have an estimate from a tax professional or current tax software, use a cautious percentage of each untaxed payment and adjust it when better information is available.
Transfer immediately
Move the reserve when each payment arrives. Waiting until month-end makes it easier to spend money that may be needed for estimated taxes.
Review quarterly
Compare year-to-date income, deductible expenses, payments already made, and updated tax estimates. Do not assume one percentage will remain accurate all year.
