Budget estimate

$200,000 – $500,000

The contract is a one‑year term with no guaranteed volume, but a CPA firm handling dozens to potentially hundreds of complex fiduciary and estate tax returns can expect substantial billing. Assuming an average of 60 cases per year at $3,000‑$8,000 per case (including research, filing, and advisory time), total revenue could range from $180,000 to $480,000. Additional fees for out‑of‑scope services (e.g., audit representation) could push the high end above $500k. Therefore, a reasonable estimate is $200k‑$500k for the initial year, with renewals potentially increasing the range.
