A dated reference, not a filing conclusion

Federal tax rates, by year.

Ordinary federal brackets, basic deductions, capital-gain ceilings, and the Social Security wage base for 2025–2027. Compare 2026 with 2027 and follow the exact source edition.

Scope: selected individual federal annual parameters only. This page does not determine filing status, dependent treatment, standard-deduction eligibility, age/blindness additions, other deductions, AMT, credit phaseouts, NIIT, state tax, or complete liability. A standard-deduction amount is not a universal filing threshold. Tax year 2027 generally concerns returns filed in 2028.

Selected annual parameters

2026 · Single

The tax year identifies the income period, not the year you open this page or submit the return.

Basic standard deduction$16,100

Before any age/blindness additions or other special deductions; eligibility is not determined.

0% capital-gain ceiling$49,450

A taxable-income ceiling. Ordinary taxable income occupies part of this space.

15% capital-gain ceiling$545,500

Eligible gains above this taxable-income ceiling enter the 20% band before other applicable taxes.

Social Security wage base$184,500

Per individual; not doubled by a joint return. Medicare uses different rules.

Read the table as a marginal schedule.

For income within a row: tax at the lower boundary + the row’s rate × (taxable ordinary income − lower boundary). The rate does not apply to every dollar. Actual return tax-table rounding can differ.

2026 → 2027

What changed for this filing status?

Dates, categories, and source indices

Find other official rate tables.

Use these official indices for their specific purpose. A monthly AFR, quarterly IRS interest rate, fiscal-year per diem, and annual-average currency rate are different kinds of numbers. Check the effective period at the source.

01 / Monthly

Applicable Federal Rates (AFRs) ↗

IRS index of revenue rulings with short-, mid-, and long-term rates and different compounding conventions.

Match the relevant month, term, compounding period, and statutory use. An AFR is not a universal loan or discount rate.

02 / Quarterly

IRS underpayment and overpayment interest ↗

Current and historical tables distinguish individuals, corporate overpayments, and large corporate underpayments.

Choose the applicable category and each relevant quarter. A balance covering several quarters cannot always be modeled with one annual rate.

03 / Annual; sometimes revised midyear

IRS standard mileage rates ↗

The IRS index separates business, charitable, medical, and qualifying moving mileage, with historical effective periods.

Match the actual travel date and purpose. A published cents-per-mile rate does not itself establish a deductible trip.

04 / Federal fiscal year and locality

GSA continental U.S. per diem lookup ↗

Lodging and meals/incidental-expense rates used for official federal travel within CONUS, searchable by locality and fiscal year.

A fiscal year is not the calendar tax year. Tax substantiation, reimbursement, and deductibility rules must be examined separately.

05 / Location and effective date

State Department foreign per diem ↗

The Office of Allowances provides the foreign per diem index and date-sensitive allowance resources. Choose “Foreign Per Diem Rates” on the official page.

Use the relevant foreign post and effective date. These government travel amounts do not, by themselves, determine a taxpayer’s deduction.

06 / Calendar-year averages

IRS yearly average currency exchange rates ↗

Annual-average reference tables and the IRS explanation of translating foreign-currency items into U.S. dollars.

The IRS does not prescribe one official exchange rate for every purpose. Annual averages are not appropriate for every transaction or reporting rule.

07 / Quarterly reporting dates; amendments possible

Treasury Reporting Rates of Exchange ↗

Treasury’s historical reporting-rate dataset offers dates, metadata, downloads, and information about amendments.

Government reporting rates are a different reference from daily spot or annual-average rates. Check the conversion rule required by the particular return or transaction.

Reviewed November 15, 2026. Selected numerical parameters share the site’s reviewed calculation engine. Linked agency indices may change after this review. Later law or guidance can change the applicable result.
