Quarterly Estimated Tax Payment Agent

Clients with uneven income often underpay estimated taxes and face penalties, or overpay and tie up cash. Before each quarterly due date, this agent updates estimated tax for each client. It uses year-to-date income from the client, last year's tax for safe harbor, and known changes such as a business sale. It calculates both the safe harbor payment, using 110 percent when prior year AGI was over 150,000 dollars, and the projected actual tax, then recommends an amount. It compares year-to-date payments with records and flags shortfalls. It checks that income data is current; if it is stale, it asks the client for an update and recalculates. It drafts payment instructions. The advisor approves every amount before it is sent to the client. Edge case: a client had a large capital gain in May, so the agent tests the annualized method to avoid an early penalty.
