There is no single federal tax-saving percentage for every high earner. For 2026, estimate your federal tax, subtract withholding and refundable credits, then check whether you meet the IRS estimated-tax rules: generally, you may need to pay during the year if you expect to owe at least $1,000 and your withholding and credits are below the required threshold. The threshold is generally based on the smaller of 90% of your expected 2026 tax or 100% of your 2025 tax—110% of 2025 tax for many higher-income taxpayers.
What “save for taxes” means under the federal rules
The IRS does not set a universal percentage of gross income that high earners must put aside. The federal estimated-tax rules determine whether you need to pay tax during the year, and how much, to reduce the risk of an underpayment penalty. They do not predict your final bill or prescribe how much cash to keep in savings.
Use the 2026 Form 1040-ES worksheet to estimate your expected federal tax, including income tax and any relevant self-employment or other taxes. Then account for expected withholding and refundable credits. The rules generally require estimated payments when you expect to owe at least $1,000 after those amounts and your withholding and credits are below the applicable required annual payment. See the IRS Publication 505 for 2026 and the IRS estimated-tax FAQ.
How to calculate the federal payment threshold
- Estimate your 2026 total federal tax. Use the Form 1040-ES worksheet, rather than applying a generic rate to gross income.
- Subtract withholding and refundable credits. If you expect to owe less than $1,000 after these amounts, the general estimated-payment requirement may not apply.
- Compare the two tax thresholds. The current-year test is generally 90% of expected 2026 tax. The prior-year test is generally 100% of 2025 tax, or 110% for many taxpayers above the high-income AGI threshold.
- Use the smaller required annual payment. Count withholding and estimated payments toward it, and check that payments are sufficient for each installment period.
The prior-year percentage generally rises to 110% if your 2025 adjusted gross income exceeded $150,000, or $75,000 if you are married filing separately. These are 2026 federal safe-harbor thresholds; the test compares your 2025 AGI with your 2025 tax and your expected 2026 tax with the current-year percentage. The IRS worksheet and Publication 505 provide the calculation details.

The $1,000 test and safe-harbor comparison answer whether estimated payments are generally required and how much may need to be paid on time to avoid a penalty. They do not establish that your total payments will equal your final 2026 tax. You may owe more when filing your return.
Withholding or estimated payments?
Withholding from wages counts toward your federal tax payments. If you are an employee and a projected shortfall appears, you can ask your employer to withhold more by submitting an updated Form W-4. Alternatively, you can make estimated payments. The right approach depends on your income sources, cash flow, and how much time remains in the year.

Timing matters. By default, the IRS treats one-fourth of your expected withholding as paid on each installment due date. You may elect to use the actual dates withholding was taken instead. This can matter if you increase withholding late in the year; consult Publication 505 or a tax professional to determine how the timing affects your calculation.

If a due date falls on a weekend or legal holiday, it shifts to the next qualifying day. You may pay the full estimated amount by the first due date or pay in installments. Installments must meet the required amounts for their periods: a later payment or refund may settle the year overall but does not necessarily erase a penalty for an earlier shortfall. Confirm the applicable dates and installment requirements in the IRS’s 2026 Publication 505.
What if income arrives unevenly?
A large bonus, stock sale, or other one-time receipt does not automatically mean a standard quarterly payment is due solely because the amount is large. The IRS says, “A sizable capital gain by itself may not give you a requirement to make a quarterly estimated tax payment.” Whether you need to pay depends on your overall tax, withholding, credits, and payment timing, not just the size of one gain. See the IRS FAQ section “Large gains, lump-sum distributions, etc.”

If your income was concentrated in part of the year, the annualized income installment method may better reflect when it arose. It calculates required installments using income accumulated through the year rather than treating annual income as evenly earned. When applying this method, the IRS directs taxpayers to use Schedule AI of Form 2210 with their return. Annualization is a calculation method, not a guarantee that a particular payment can be skipped; review the Form 1040-ES and Publication 505 instructions, or seek qualified tax advice.

When to revisit your estimate
Recalculate when a change could materially affect your expected tax or payment timing. Relevant changes include salary, bonuses, equity vesting, investment income, business income, deductions, and credits. If the change occurs after an installment date, check the period-by-period rules rather than assuming an updated annual estimate cures any earlier shortfall.
