Shifting income between tax years deliberately means choosing when income is recognized so it lands in the year where it is taxed at a lower rate. You either defer income into a later year or accelerate it into the current one. This is not hiding income or evading tax. It is selecting the year of recognition within IRS rules, and the strategy only pays off when you can see the next year coming.

What does shifting income between tax years deliberately actually mean?
Shifting income between tax years deliberately means deciding which tax year a given dollar of income lands in, rather than letting the calendar decide for you. It is a timing decision, not a question of whether the income gets reported.
This is distinct from income splitting between people, such as family members or entities. Income splitting moves income from a higher-bracket taxpayer to a lower-bracket one. Timing moves income from one year to another for the same taxpayer. The two strategies are often confused, but they operate through different mechanisms.
The two directions are deferral and acceleration. Deferral pushes income into a future year, typically when you expect to be in a lower bracket or have offsetting deductions. Acceleration pulls income into the current year, usually because the current year is unusually low-income or carries large deductions.
The practice is legal when it stays within IRS guidelines. According to Cerebral Tax Advisors, income shifting is a legal method for lowering tax burden provided the taxpayer stays within IRS guidelines. The line between timing and evasion is documentation and substance. A transaction must have real economic substance and be reported under a permissible accounting method.
This article is general information, not tax advice for a specific situation. Your facts, entity structure, and accounting method determine what is available to you.
Why does the year income lands in matter so much?
The year income lands in matters because the U.S. tax system is progressive. Each additional dollar can push you into a higher bracket and trigger federal income tax, net investment income tax, Medicare surtaxes, and state taxes, according to LA Wealth Planning. An extra dollar in the wrong year can cost more than the same dollar in a lower-income year.
When tax rates are stable, deferring as much income as possible from one year to a later year and accelerating deductions postpones the payment of the tax, according to Westwood Group. You keep the cash longer, which has real value even if the eventual tax bill is the same.
The flip side is a year with unusually low income or large offsetting deductions. That is a year to pull income forward into. A loss year, a heavy equipment purchase, or a business startup year can absorb income at a lower effective rate.
Timing decisions only work when you can reasonably forecast next year's income. Without a credible projection, you are guessing. The strategy depends on knowing, not hoping, what the next year looks like.
What are common ways business owners shift income between years?
Business owners shift income between years through several practical levers. The most straightforward is maximizing contributions to tax-deferred vehicles such as 401(k)s, SEP IRAs, and defined benefit plans, which reduce current taxable income, according to LA Wealth Planning. These contributions lower the current year's income and defer tax until withdrawal.
Timing asset sales is another direct lever. Selling an asset in January versus December can shift an entire capital gain into a different tax year, according to LA Wealth Planning. The sale date, not the decision date, controls the year of recognition.
Accelerating deductions and deferring invoices or receivables works where the accounting method allows. Cash-basis taxpayers have more room to time receipts and payments. Accrual-basis taxpayers have less flexibility but still control the timing of certain expenditures.
Annuity treatment offers another option. Income generated by an annuity accumulates tax free until funds are withdrawn, and the interest is not taxable in the current year as long as no withdrawals are made, according to Westwood Group. The deferral is built into the product.
Spencer Accounting Group's Strategic Tax Planning is built around forward-looking timing decisions like these. The work is sequencing income and deductions across years so the tax position is designed rather than discovered in April.
How does shifting income to family members differ from shifting it between years?
Shifting income to family members is a different mechanism from shifting it between years. Income shifting, also known as income splitting, divides income in a way that lowers overall taxes, typically shifting income from higher-bracket taxpayers to lower-bracket ones, according to Westwood Group. The recipient changes; the timing may not.
Hiring your child in the business is one common approach. Wages paid to the child are deductible to the business as a business expense and taxed in the child's typically lower bracket, according to Cerebral Tax Advisors. But the pay must be reasonable. Paying a child an outsized hourly rate for light office work invites IRS scrutiny.
The kiddie tax limits how much investment income a child can absorb at low rates. In 2023, the kiddie tax threshold was $2,500, with the first $1,250 tax free and the next $1,250 taxed at the child's rate, according to Westwood Group. These figures change year to year, so current amounts should be confirmed.
Gifting limited partnership interests up to the annual gift tax exclusion shifts future income to the recipient. The 2023 annual gift tax exclusion was $17,000 per recipient, according to Westwood Group. That figure also adjusts annually.
State-level rules interact with these federal strategies and can change the math. A state with its own income tax may treat the shifted income differently than the federal return does.
What changes when the business is an S corporation or a C corporation?
Entity choice changes which timing strategies are available. In a Subchapter S corporation, gains escape taxation at the corporate level and are taxed immediately to shareholders whether or not distributed, according to a Maryland Law Review analysis. The income lands on the owner's personal return in the year earned.
That pass-through treatment means S corporation income does not sit inside the entity waiting to be distributed. Timing levers sit at the entity and salary level. The owner can time salary, distributions of previously taxed income, and entity-level deductions, but not the recognition of the underlying corporate income.
A Subchapter C corporation faces potentially two levels of taxation, one at the corporate level and one at the shareholder level, according to the same Maryland Law Review analysis. That structure creates different timing questions. Corporate income is taxed in the year earned at corporate rates, and shareholder income is taxed again when distributed.
Entity choice therefore shapes which timing strategies are available and who bears the tax. The same economic activity can produce different year-of-recognition outcomes depending on whether the business is a sole proprietorship, S corporation, or C corporation.
Is shifting income between tax years legal?
Yes, when it stays within IRS guidelines. Income shifting is described as a legal method for lowering tax burden, according to Cerebral Tax Advisors. The practice has operated within the tax code for decades.
The distinction is substance and disclosure. Reporting income in the correct year under a permissible accounting method is planning. Omitting income or misstating the year of receipt is evasion. The same transaction can be either depending on how it is documented and whether it has economic substance.
Poorly documented timing positions are what turn a planning decision into a problem. A deferred invoice that is not real, or a family wage that is not actually paid, crosses the line. Penalties and consequences apply when timing crosses into evasion, and the specifics depend on the facts.
What should you confirm before relying on a timing strategy?
Confirm current-year figures before acting. Bracket thresholds, kiddie tax limits, gift exclusions, and contribution caps all adjust annually. The research cited in this article includes 2023 amounts, so 2026 numbers should be verified.
Filing deadlines shift year to year and should be confirmed for the current tax year. A timing plan built around a deadline that has moved can fail.
Your accounting method and entity structure constrain which levers you actually have. Cash-basis taxpayers have different options than accrual-basis taxpayers. S corporation owners face different timing rules than C corporation shareholders.
A timing plan depends on a credible forecast of next year's income, not a hope. If the forecast is wrong, the income lands in the wrong year and the strategy backfires.
If returns are already behind, get compliant first. Spencer Accounting Group's Back Tax Return Filing sequences catch-up work before planning, so the timing strategy is built on a current baseline.
Key Takeaways
- Shifting income between tax years deliberately means choosing when income is recognized so it is taxed in the lower-rate year, not hiding it.
- The progressive U.S. system means an extra dollar in the wrong year can trigger higher brackets plus net investment income tax, Medicare surtaxes, and state taxes.
- When rates are stable, deferring income and accelerating deductions postpones the tax payment.
- Selling an asset in January instead of December moves the entire capital gain into a different tax year.
- Income splitting between family members is a separate strategy from timing, and the kiddie tax caps how much investment income a child can absorb at low rates.
- S corporation income is taxed to shareholders in the year earned whether distributed or not, which limits where timing levers sit.
- Bracket thresholds, kiddie tax limits, and gift exclusions change annually, so current figures should be confirmed before acting.
