MyTaxQuarter helps 1099 contractors calculate quarterly estimated taxes, set the right freelance rate, and estimate ACA health insurance subsidies — all free, no signup, no data stored. Built by a freelancer, for freelancers.

Hey Product Hunt! 👋 I built MyTaxQuarter after getting hit with a $4,200 surprise tax bill in my first year of freelancing. Every calculator I found was either too generic, required signing up, or didn't explain the math. So I built one that actually shows the full breakdown. What's included — all free, no account needed: 🧮 1099 Tax Calculator Calculates quarterly federal + state taxes with SE tax wage base cap, W-2 income stacking, safe harbor 100%/110% rule based on prior year AGI, and a printable PDF summary for your accountant. 💰 Freelance Rate Calculator Works backwards from your desired take-home income — accounts for taxes, health insurance, retirement, and non-billable hours. Most freelancers underprice by 40-60%. 🏥 ACA Subsidy Estimator Estimates your 2026 Premium Tax Credit. Includes cliff warning if you're close to the 400% FPL income limit where your entire subsidy disappears — and strategies to reduce your MAGI to stay under it. All calculations happen in your browser — nothing is stored or sent to any server. No signup, no email required. Happy to answer any questions about the tax math or how I built it. What would you add next? 🙏

Love that it doesn't ask for an email just to run the numbers. The ACA subsidy estimate was surprisingly close to what I got from a longer spreadsheet I usually use.

Love that it's free and no signup, super respectful of user privacy. One thing that would help me out: a simple export to PDF or CSV for the quarterly tax summary so I can hand it straight to my accountant without retyping everything.

How does it handle state-specific tax rules since freelancing across state lines can get pretty different?
