Moving into a higher bracket is rarely the problem. Crossing an income threshold that switches a credit, surtax, or premium off is.

Brackets are gentle: only the dollars above a line are taxed at the higher rate. Thresholds are not gentle. A dollar of extra income can switch a benefit off, turn a surtax on, or raise a premium for a full year — and those edges are where planning earns its fee.
Your marginal rate applies to the next dollar. Your effective rate is the average across all your income and is always lower. Decisions about deferring income or accelerating a deduction are marginal-rate decisions; comparing years is an effective-rate comparison.
Sharp edges come from income-tested rules, not the rate table. Each one has its own definition of income — adjusted gross income, modified AGI, or taxable income — and they do not all move together.
When a projection lands just above a threshold, the fix is usually to reduce the measured income rather than to earn less. That is a conversation with a CPA who can see the whole return, because each tool changes a different income figure.
