# Quarterly Estimated Payment Reminder

Drafts a reminder email for an upcoming estimated tax payment with the amount, due date, and exact payment steps. Send it about two weeks before each quarterly deadline.

## Prompt

## Context
You write client emails for an accounting practice. A federal estimated tax payment deadline is approaching. The client already has a payment amount from us. This email reminds them; it does not recalculate anything.

Client first name: [CLIENT FIRST NAME]
Quarter and due date: [QUARTER AND DUE DATE]
Federal payment amount: [PAYMENT AMOUNT]
State estimate, if any: [STATE AMOUNT AND DUE DATE or "none"]
Payment method instructions: [PAYMENT METHOD — e.g., IRS Direct Pay, EFTPS, mailed voucher]

## Task
Write a reminder email under 150 words. Include: the amount, the due date, exactly how to pay, what to send us as confirmation, and one line on what happens if they skip it (underpayment interest accrues — keep it factual, not scary).

## Standards
- Subject line included. Plain and specific: amount and date in the subject.
- No recalculation, no tax advice, no commentary on whether the amount could change.
- If the client pays state estimates too, list federal and state as separate line items with separate instructions.
- Close with how to reach us if their income has changed enough to revisit the estimate.

If the amount or due date is missing, ask me — do not guess either one.

## Variables

- [CLIENT FIRST NAME]
- [QUARTER AND DUE DATE]
- [PAYMENT AMOUNT]
- [STATE AMOUNT AND DUE DATE]
- [PAYMENT METHOD]

## Input checklist

- [ ] The voucher amount and due date from your tax software — never let the AI supply either
- [ ] The client's payment method and any system they use: Direct Pay, EFTPS, or mailed check
- [ ] State estimate amount and due date, if applicable
- [ ] Anonymize client identifiers or confirm your AI tool is approved under your firm's confidentiality policy; estimate amounts derived from a return carry IRC Sec. 7216 restrictions

## Verification checklist

- [ ] The amount in the email matches the voucher in your file to the dollar — check against your workpapers, not memory
- [ ] The due date is the actual IRS date for that quarter, adjusted for weekends and holidays; AI gets the June and September dates wrong often
- [ ] Federal and state amounts are not swapped or merged into one figure
- [ ] Payment instructions match how this client pays — EFTPS steps sent to a Direct Pay client cause support calls
- [ ] The skipped-payment line is factual and does not quote a specific penalty amount
- [ ] Subject line shows the right amount and the right date

## Sample output

Sample output — AI-generated from sample inputs:

Subject: Estimated tax due June 15 — $4,800 federal, $900 Ohio

Hi Priya,

Your second-quarter estimated payments are due Monday, June 15.

Federal: $4,800. Pay at IRS Direct Pay (irs.gov/payments). Choose "Estimated Tax," Form 1040-ES, tax year 2026.

Ohio: $900. Pay through your OH|TAX eServices account, or mail the IT 1040ES voucher we sent in April.

Once you pay, forward the confirmation emails so we can note your file.

If you skip a payment, the IRS charges interest on the shortfall until it is paid. Not a crisis, but it adds up.

One more thing: these amounts assume your income looks like last year. If 2026 is running well above or below that, reply and we will rerun the numbers before you pay.

## Customization notes

Turn this into a merge template by keeping the bracketed fields as merge fields in your email tool, then batch all Q2 clients in one run. For EFTPS clients, paste their standing instructions into the payment method field once and reuse each quarter. Add a second, shorter reminder three days before the deadline for chronic late payers.
