A one-tab planner for self-employed sellers: type your estimated annual profit and the sheet picks a set-aside % from the income-band guidance table (15% up to $12,000; 20% to $30,000; 25% to $60,000; 30% above). Each month, type that month's profit and it sets the money aside on paper, keeps a running pot total, and lists the quarterly estimated-tax reminder dates (Jan 15, Apr 15, Jun 15, Sep 15) so the payment comes from the pot, not from spending money.

• Monthly profit in, set-aside out — automatically, from the guidance band

• Running pot total, month by month

• Quarterly estimated-tax reminder dates on the sheet

• Set-aside % follows your income band

• Works in Excel, Numbers, and Google Sheets

• clean copy + filled demo copy included
