Everything in This Tax Tracker
Your Tax Picture at a Glance
Open the dashboard and see where you stand. Net taxable, projected total tax, payments to date, and balance due across the top - effective rate, safe-harbor target, and total deductible across the bottom. A status banner flags whether payments to date meet the safe-harbor target.
- 7 KPI cards covering taxable, liability, paid, and balance
- Safe-harbor status banner
- Quarterly Payments and Deductible by Category charts
Track Every Source by Month
Three sample income sources - consulting, recurring retainers, and product sales - across all 12 months, with row totals and a grand total. Add or rename sources to match your business; the dashboard, Tax Summary, and effective rate read from the totals.
- Three sources by default, add as needed
- 12 months of monthly entries per source
- Row totals and grand total auto-calculated
Deductible Expenses, Per-Category %
Eight default categories - home office, mileage, equipment, software, professional fees, travel, meals, other - each with a deductibility percentage you can override. Deductible amount equals raw amount times percentage, so meals at 50% works out of the box.
- Eight default deductible categories
- Editable deductibility percentage per category
- Raw and deductible totals on every row
All Four Quarters, Federal and State
Each quarter has a due date and two inputs - federal and state payment. Row totals show what you sent that quarter; the column total feeds the Paid KPI on the dashboard. Q1 and Q2 are filled with sample data; Q3 and Q4 are blank, ready for entry.
- Q1 through Q4 with official due dates
- Federal and state inputs per quarter
- Year-to-date payments roll into the dashboard
Step-by-Step Calculation
Walk down the page from gross income to balance due. Gross income, total deductions, net taxable - then federal, self-employment, and state liability applied at the rates you set - with total liability, payments to date, and balance due on bold rows.
- Gross to net taxable to liability
- Federal + SE + state shown on separate lines
- Total liability, paid, and balance due footer
Quarterly Pace and Top Deductions
Two charts on the dashboard tell the story. Quarterly Payments shows what you sent each quarter as a column chart. Deductible by Category ranks the eight deduction categories so you can spot what is driving your deductible total.
- Quarterly Payments column chart
- Deductible by Category column chart
- Both update from the source sheets
Rates and Safe-Harbor, in One Place
Business name, tax year, and currency at the top. Then editable rates - federal, self-employment, and state - applied to net taxable. Safe-harbor inputs include prior-year tax and the safe-harbor percentage (110% by default) so the dashboard can show whether year-to-date payments are on pace.
- Business name, tax year, currency
- Federal, SE, and state rates - all editable
- Prior-year tax and safe-harbor percentage
Customizable & Flexible
Adapt the template to your situation. Add income sources, rename deduction categories, or change tax rates to match your jurisdiction - every figure updates. Planning tool only; confirm specifics with a qualified professional. Works identically in Excel and Google Sheets.
- Add sources and rename deduction categories
- Tune federal, SE, state rates and safe-harbor %
- Excel and Google Sheets compatible
