Estimated Tax
If your business is a pass-through entity (sole prop, partnership, S-corp), the IRS expects quarterly estimated tax payments instead of one big lump at filing. Geekonomics estimates what those payments should be from your actual P&L and tracks what you've paid.
Configuration
Go to Settings → Tax Settings and fill in:
- Filing status — single, married filing jointly, head of household, etc.
- State — your state of residence (used for state estimated tax, where applicable).
- Federal effective rate — your best-guess blended rate (or what your CPA said).
- State effective rate — same for state.
- Self-employment rate — 15.3% is the standard, but it can vary.
These rates drive the math. They're a planning tool — when your actual situation diverges (a big deduction, a switch in entity structure), update them.
Quarterly Estimate
Open /tax/estimated. Geekonomics computes year-to-date net income from your P&L, applies your configured rates, and divides into quarterly installments using the standard 4/15, 6/15, 9/15, and 1/15 due dates. The page shows what you owed at each quarter, what you've paid, and the running balance.
A safe-harbor column shows the IRS's underpayment-penalty safe harbors (100% of last year's tax liability, or 110% if your prior AGI exceeded the threshold). Hit those numbers and you avoid the underpayment penalty even if your actual tax due ends up higher.
Recording a Payment
When you make a quarterly payment, click Record Payment. Enter the bank account, the date, and the federal and state amounts. Geekonomics creates an expense transaction tagged with a system "Estimated Tax" category so the cash leaves the right account and shows up in your reports.
WARNING
This is a planning tool, not a CPA substitute. Effective rates, deductions, depreciation, credits, and a dozen other factors change what you actually owe at filing. Use the estimate as a budgeting guide; verify with a tax professional before you submit anything to the IRS.
