If you want a focused answer to one specific question, jump straight to one of these:

What's New in 2026

The 2026 tax year keeps the same seven federal rate bands set in 2018 — 10, 12, 22, 24, 32, 35, and 37 percent — but every income threshold shifts up for inflation. For a single filer the 22 percent bracket now starts at $49,475 (up from $48,475 in 2025), and the top 37 percent rate kicks in at $638,900 instead of $626,350. The standard deduction climbs to $15,350 single / $30,700 MFJ / $23,100 head of household. The Social Security wage base rises from $176,100 to $184,500, lifting the maximum employee FICA hit by $521.

Retirement and health-savings limits also step up. The 401(k) elective deferral limit goes from $23,500 to $24,000, with the 50-plus catch-up holding at $7,500 and the 60-to-63 super catch-up at $11,250. The IRA limit stays at $7,000 for 2026 (still $1,000 catch-up at 50+). HSA contribution caps rise to $4,400 self-only and $8,750 family. The annual gift-tax exclusion is $19,000 per recipient. The TCJA individual rate cuts remain in effect, the SALT deduction cap is still $10,000, and the OBBBA provisions that took effect mid-2025 are now fully phased in. Capital gains rates remain 0/15/20% on long-term holdings, with 2026 0% upper limits at $49,400 single and $98,750 MFJ.

Which Calculator Do I Need?

"I'm a W-2 employee."

The two-step combo: Paycheck Calculator for the per-cheque take-home, then Refund Estimator in November or December to see whether your withholding will match your annual liability. If they're off by more than a couple of thousand dollars, update your W-4 rather than letting it become an April surprise. If your situation is mostly W-2 wages with no investments, you probably don't need a paid product like TurboTax Deluxe.

"I'm a freelancer or 1099 contractor."

Run the Self-Employment Tax Calculator first — the 15.3% on net SE income is the single biggest number freelancers underestimate. Then the Quarterly Estimated Tax tool to schedule your four 1040-ES payments. If you're deciding whether to keep contracting or take a salaried offer, the 1099 vs W-2 Comparison shows the after-tax difference on the same gross.

"I sold stocks or crypto this year."

For listed stocks and ETFs, the Capital Gains Tax tool sorts your sales into long-term (0/15/20%) and short-term (ordinary income) buckets. For crypto, the Crypto Tax Calculator handles multiple lots across tokens. Before December 31, run Tax-Loss Harvesting to see which losers you can sell to offset gains, but check the Wash Sale rule before re-buying within 30 days.

"I'm starting a business."

Decide entity first: the LLC vs S-Corp Comparison shows when the S-corp salary/distribution split actually saves SE tax (typically once net profit clears $50–60k). Then run Self-Employment Tax for your projected first-year profit, and Section 179 if you're buying equipment in year one — the 2026 limit is $1.28 million.

"I'm planning retirement."

The 401(k) Tax Savings Calculator shows the current-year deduction value of contributing pre-tax. Pair it with Traditional vs Roth to decide whether to take the deduction now or pay tax now for tax-free withdrawals later. The rough rule: Roth wins if your tax rate in retirement will be higher than today, traditional wins if it will be lower.

"I bought a house."

The Property Tax Calculator gives the assessed-value × millage estimate for your area. Mortgage interest is deductible on Schedule A, but with the 2026 standard deduction at $30,700 MFJ, most homeowners now take the standard rather than itemizing — run Standard vs Itemized to confirm before paying for a paid filing product.

Popular Tax Scenarios With Numbers

Scenario 1 — Single filer, $75,000 salary

Single W-2 employee, $75,000, no dependents, taking the standard deduction. Taxable income = $75,000 − $15,350 = $59,650. Federal tax under 2026 brackets is about $8,251 (10% on $12,150 + 12% on $37,325 + 22% on $10,175). FICA adds 7.65% × $75,000 = $5,738. Combined federal + FICA: roughly $13,989, or 18.7% of gross. Take-home before state tax: about $61,011. Run the per-paycheck split with the Paycheck Calculator.

Scenario 2 — Freelancer with $100,000 in 1099 income

Self-employed individual, $100,000 net Schedule C profit, single. Self-employment tax: 15.3% × ($100,000 × 0.9235) = about $14,130. Half of that ($7,065) is deductible above the line. Federal income tax on the resulting AGI of $92,935, minus the $15,350 standard deduction, is roughly $11,300. Plan for four quarterly estimated payments of about $6,358 each. Use the SE Tax Calculator and Quarterly Estimated Tax.

Scenario 3 — Married couple with $50,000 in stock gains

MFJ filers, $150,000 wages plus $50,000 in long-term capital gains. After the $30,700 standard deduction, ordinary taxable income is $119,300 and ordinary federal tax is about $17,353. The 2026 MFJ 0% LTCG bracket goes up to $98,750 of total taxable income — all filled by ordinary income — so the entire $50,000 of LTCG is taxed at 15% = $7,500. Total federal: roughly $24,853. Capital Gains Calculator shows the exact bracket split.

Scenario 4 — Two-income married couple at $200,000 combined, MFJ

Both spouses W-2 employees, $100,000 each, MFJ, taking the standard deduction. Taxable income = $200,000 − $30,700 = $169,300. Federal tax under 2026 MFJ brackets: 10% on $24,300 ($2,430) + 12% on $74,650 ($8,958) + 22% on $70,350 ($15,477) = $26,865 total. FICA at 7.65% on each spouse's $100,000 wages = $15,300 combined. No Additional Medicare (combined under $250k MFJ threshold). Combined federal + FICA: roughly $42,165, or 21.1% of gross.

Scenario 5 — Retiree with Social Security, IRA withdrawals, and capital gains

Single retiree age 67. Income: $30,000 Social Security benefits, $40,000 traditional IRA withdrawal, $20,000 long-term capital gains. Up to 85% of Social Security is taxable because provisional income exceeds $34,000, so $25,500 of SS counts as gross. AGI = $40,000 + $20,000 + $25,500 = $85,500. Standard deduction with the 65+ add-on = $15,350 + $2,050 = $17,400. Taxable income = $68,100. Ordinary portion = $48,100 (taxable income minus LTCG), federal ordinary tax ≈ $5,529. The first $1,300 of LTCG falls in the 2026 single 0% bracket (up to $49,400 of total taxable income); the remaining $18,700 is taxed at 15% = $2,805. Total federal: about $8,334. State tax depends on residency — Florida, Texas, and seven others charge nothing on retirement income.

When These Calculators Are Not Enough

These tools are accurate for the 85% of taxpayers whose returns are W-2 wages, simple 1099 income, mainline investments, standard retirement accounts, and standard deductions. If your return includes any of the following, treat the calculator output as a starting estimate and bring in either a paid product or a CPA before filing:

  • Foreign earned income (Form 2555 exclusion, foreign tax credit on Form 1116) — both have phase-outs and treaty interactions that no general calculator handles.
  • K-1 partnership or S-corp pass-through income — basis tracking, at-risk rules, and the QBI deduction get complicated fast.
  • Rental property with depreciation recapture on sale — section 1250 unrecaptured gain is taxed at 25%, not the usual LTCG rate.
  • ESPP or RSU stock awards — wages portion vs capital gains portion, with the ESPP qualifying-disposition trap.
  • AMT exposure from large ISO exercises or high SALT in pre-2018 years.
  • NIIT when MAGI is just over the threshold and you can plan around it.

For any of the above, the right tool is TurboTax Premier or Home & Business, ProConnect, Drake, or a $400–$1,200 CPA engagement — not a free calculator. The honest answer is that complex returns reward professional review, and the tax savings from getting one obscure item right usually beats the prep fee.

Federal Versus State Tax

Federal tax is the same in all 50 states. Wages earned in Florida and wages earned in California pay the same federal brackets. What changes is the state layer on top. Nine states charge no state income tax in 2026: Alaska, Florida, Nevada, New Hampshire (interest and dividends only), South Dakota, Tennessee, Texas, Washington (capital gains over $250k only), and Wyoming. At the other end, California's top bracket is 12.3% (13.3% with the mental-health surtax on income over $1 million), Hawaii hits 11%, New York runs 10.9% at the top, and New Jersey reaches 10.75%.

Cities can add their own income tax: New York City layers 3.078% to 3.876% on top of state, Philadelphia adds 3.75%, Detroit and several Ohio cities run 1–4% local income tax, and San Francisco has a gross-receipts business tax. Property tax varies even more wildly — New Jersey averages 2.23% of home value annually, while Hawaii averages 0.32%. Most of the calculators on this hub handle federal. For state-specific amounts use the State Income Tax Calculator for income, the Property Tax Calculator for homeowners, and the Sales Tax Calculator for combined state + local sales rates.

Frequently Asked Questions

Yes. All 30+ calculators are free with no sign-up. Results are calculated in your browser and never sent to a server. You can use them as often as you like, on any device. There are no usage limits, no premium tier, and no "upgrade for the full result" gates — what you see is the full output.
The calculators use IRS-published brackets, standard deductions, FICA rates, capital-gains thresholds, and retirement contribution limits for the selected tax year. They produce reliable estimates for planning. They do not model every credit, AMT, NIIT exception, or state-by-state nuance. Treat the result as the starting point a CPA would refine, not as your filed return. If you spot a number that looks off, the underlying constants live in assets/tax-data.js on this site and can be cross-checked against the source IRS document.
Tax years 2025 and 2026. The default is 2026 (the year you will file in early 2027). Use the year selector at the top of any calculator page to switch. Brackets, deductions, FICA wage base, and contribution limits all change with the selector. The 2024 figures are referenced in the historical comparison tables only — they are not selectable in the calculators themselves.
The federal calculators stop at federal tax. For state amounts, use the State Income Tax Calculator (built-in brackets for the largest states), the Sales Tax Calculator, and the Property Tax Calculator. Nine states have no state income tax in 2026: Alaska, Florida, Nevada, New Hampshire (interest and dividends only), South Dakota, Tennessee, Texas, Washington (capital gains over $250k only), and Wyoming.
No. These are estimators, not filing software. For filing, use IRS Free File (free for AGI up to $84,000), an authorised e-file provider like TurboTax or H&R Block, or a CPA. Use the calculators here to forecast your liability, set withholding on Form W-4, or plan quarterly estimated payments.
The 2026 brackets keep the same seven rates (10, 12, 22, 24, 32, 35, 37 percent) but the income thresholds shift up for inflation. For a single filer the 22 percent bracket now starts at $49,475 (up from $48,475 in 2025), and the top 37 percent rate begins at $638,900 (up from $626,350). Standard deduction rises to $15,350 single and $30,700 MFJ. The Social Security wage base climbs to $184,500, the 401(k) employee contribution limit rises to $24,000, and the LTCG 0% upper threshold is $49,400 single / $98,750 MFJ.
Use the filter box at the top of this page, or work through the Which Calculator Do I Need decision tree above. A W-2 employee typically wants the Paycheck Calculator plus the Refund Estimator. A freelancer wants Self-Employment Tax and Quarterly Estimated Tax. An investor selling stocks wants Capital Gains Tax and Tax-Loss Harvesting. A retiree wants Federal Income Tax and Capital Gains Tax with the Social Security taxability rules applied.
The IRS does not certify third-party calculators. The rates, brackets, and limits used here come straight from IRS Revenue Procedures, Publication 15, Publication 505, Publication 334, and SSA wage base announcements. The arithmetic is standard tax math you can replicate by hand from those documents — there is no proprietary model.
Partly. The Traditional vs Roth calculator shows the after-tax value of contributing to one account or the other. It does not yet model a multi-year Roth conversion ladder, which depends on year-by-year ordinary income, IRMAA cliffs, and state tax treatment of the conversion. For a real conversion strategy across five to ten years, build the year-by-year schedule with a CPA or a planning tool like NewRetirement, Holistiplan, or Boldin.
Federal rates are updated when the IRS publishes the annual Revenue Procedure (usually in October or November for the following year). The FICA wage base updates when the SSA releases its OASDI figure each October. State rates are reviewed at the start of each tax year. The current data set was last refreshed in January 2026 and is timestamped in the schema markup on this page.
