Why This Tool Exists
When people get behind on taxes, they usually try to fix it with a giant Q4 payment. That can work, but it is not always the cleanest execution path.
This planner helps you build a simple catch-up number and split it into per-paycheck withholding. You can also compare the equivalent quarterly payment plan.

Pick a target amount to cover by year-end, then split the gap across paychecks or quarterly payments.

What This Tool Is
This is a cash-flow execution tool. You choose a target dollar amount you want covered by year-end, then you spread the remaining gap across paychecks.
It does not replace a tax projection. It gives you a clean plan you can execute with fewer surprises.
Execution Notes
If you use this, update your W-4 or payroll withholding settings and confirm the change shows up on the next pay stub.
Re-run the tool when income changes or you add a new income stream.
Keep the output in your year folder so you can explain why you chose a catch-up plan.
Documentation Checklist (Keep It Defensible)
- Create a one-page objective memo before you execute (what outcome you are trying to buy).
- Store your assumptions and calculations in a dated PDF (no year-end reconstructions).
- Keep evidence in the same folder structure every month (receipts, logs, approvals).
- Ask your CPA what would make this easy to sign off on, then build that packet.
