Built for tax year 2026 · Educational template — not tax advice (full note at bottom)

Freelance income is great. Guessing what to set aside every quarter is not.

One Google Sheet to log income and expenses, sort them into Schedule C categories, watch the four deadlines, and see how the IRS's own 1040-ES worksheet method estimates what to set aside. One-time purchase. No subscription.

Nobody withholds taxes for you now. That surprise has a due date.

"Wait — I owe how much?" Your clients pay you the full invoice. The part that used to disappear from a paycheck is now your job to set aside — before April makes it a lump sum.

"Which of these is even deductible?" Software, home office, mileage, that laptop… Schedule C has categories for all of it. Most first-year freelancers track none of it until the deadline panic.

"When am I supposed to pay?" Four dates a year, and they're not when you'd guess. Miss them and the IRS can add penalties on top of the tax.

What's inside the Command Center

1. Income & expense log — every entry maps to an IRS Schedule C category from a dropdown.
2. Quarterly estimate worksheet — the published IRS Form 1040-ES method, every formula visible and cited.
3. Deadline dashboard — all four due dates with live status.
4. Safe-harbor tracker — the 100%/110% prior-year method in plain arithmetic.
5. No subscription — $29 once, in your Google Drive forever. Subscription apps charge $16–20 every month.
6. 2026 edition — version-stamped; rates and thresholds cited to Rev. Proc. 2025-32 and the 2026 Form 1040-ES.

Built for one specific person

This is for you if… this is your first or second year with 1099 income in the US; you freelance as a designer, writer, developer, VA, or consultant; you'd rather own a $29 sheet than rent a $19/month app.

It's not for… S-corps, partnerships, businesses with employees, or multi-state situations — that's what a CPA or enrolled agent is for, and worth it.

The honest fine print: This is an educational template for organizing your own records and understanding published IRS worksheet methods. It is not tax, legal, accounting, or financial advice. It doesn't know your situation, doesn't guarantee any outcome, savings, or compliance, and isn't a substitute for a qualified tax professional. Built for tax year 2026; rates and thresholds update annually. Built by Holder Ventures with AI assistance and human review.
