What tax rate structure starts at one level and increases as the value of the estate increases?

• A. Annuity
• B. Sliding scale
• C. Arm's-length transaction
• D. Probate estate

Answer: (B)

The main idea is a progressive tax rate structure, described here as a sliding scale. In this setup, the tax rate begins at a low level for smaller estates and then increases as the estate’s value grows, moving into higher brackets. This means portions of the estate are taxed at higher marginal rates as value thresholds are crossed. It mirrors how many tax systems are designed to place a greater relative burden on larger estates.

Why this fits best: the phrase “starts at one level and increases as the value increases” directly matches a sliding scale, where the rate climbs in steps (or brackets) as the base (the estate value) rises. The other terms don’t describe a rate structure: an annuity is a payout product, an arm's-length transaction is about negotiating prices between unrelated parties, and a probate estate refers to the estate being probated, not how taxes apply.
