How to use it
- Enter monthly gross income and deductible expenses, effective federal and state rates, prior-year total tax, filing status, and whether AGI was above the safe-harbor threshold. This planner is about practical cash set-asides, not exact return preparation.
- Read recommended set-aside percent, monthly reserve amount, and the quarterly payment schedule. Safe harbor often means paying 100% of prior-year tax, or 110% if prior-year AGI exceeded $150,000.
- If current-year profit is rising fast, using last year's safe harbor can still leave a large April balance due. The reserve rate needs to reflect self-employment tax and the current year's income trend, not just the legal minimum.
- Automate a transfer from each payout into a dedicated tax account and put IRS estimated-payment dates on your calendar. Use the side hustle tax calculator to sanity-check the effective rate whenever income mix changes.
- Re-run every month and especially before each quarterly due date. Track reserve balance, year-to-date profit, and whether you are staying above the safe-harbor path.

Agent FAQ
Should ChatGPT, Claude, or another agent click through the UI?
No. Start with /agent-tools.json, then follow the tool's contract URL. The page UI is for human review, not parameter discovery.
When do tools show Quick and Advanced?
Every tool opens in Quick Start first. Advanced Controls keeps the same scenario, reveals more assumptions or diagnostics, and every tool keeps AI integrations inline below the instructions.
When should an agent still open the browser page?
Open it when a human wants to sense-check the output, review the chart, or keep exploring related tools after the calculation finishes.
Questions people usually ask
How does safe harbor work here?
The planner compares 90% of current-year estimate with prior-year safe-harbor target (100% or 110% for high AGI) and uses a penalty-safe annual reserve target.
Can I use this for seasonal gig income?
Yes. Enter monthly gross and expense values. Quarter targets are weighted by projected net income to reflect uneven earnings.
Is this a filing tool?
No. It is a reserve-planning calculator and does not submit tax filings.
Is this professional advice?
No. Outputs are planning estimates only — not financial, tax, or investment advice.
