Tax Planning Tools
Calculators That Save Real Money
Every tool here represents a real tax strategy. Run the numbers, then take action.
W-4 Withholding Optimizer Popular
Are you over-withholding (giving the IRS a free loan) or under-withholding (risking a penalty)?
▼
Estimated Annual Tax Owed—
Current Annual Withholding—
Expected Refund / Balance Due—
Ideal Per-Paycheck Withholding—
A large refund feels good but means you gave the IRS an interest-free loan all year. Optimize your withholding to break even or owe a small amount.
Roth Conversion Analyzer Advanced
Should you convert Traditional IRA funds to Roth? Find the optimal conversion amount to fill your bracket.
▼
Current Bracket—
Tax Cost of Conversion—
Bracket After Conversion—
Optimal Conversion to Fill Bracket—
💡 Roth conversions make sense in low-income years, early retirement, or when filling lower brackets. The goal: pay tax now at a lower rate than you'll pay in retirement.
Capital Gains Tax Calculator
Short-term vs. long-term: the difference in tax owed can be enormous. Know before you sell.
▼
Total Gain$15,000
Tax Rate Applied—
Tax Owed—
After-Tax Proceeds—
💡 Holding an investment just one day past the 1-year mark can dramatically reduce your capital gains rate. Plan your sales around this threshold.
Self-Employment Tax Calculator
Freelancers and 1099 workers owe self-employment tax on top of income tax. Know your real tax burden.
▼
Net Self-Employment Income—
Self-Employment Tax (15.3%)—
Federal Income Tax—
Total Tax Burden—
Effective Total Rate—
Quarterly Estimated Tax—
💡 Self-employed people pay both the employee AND employer portions of Social Security and Medicare (15.3%). You can deduct half the SE tax on your return — and deduct contributions to a Solo 401(k) or SEP-IRA to dramatically cut this bill.
HSA Triple Tax Advantage Calculator
The most tax-advantaged account available. Most people vastly underuse it. See what you're missing.
▼
Annual Tax Saved (upfront)—
Total Contributions—
Account Value (invested)—
Total Tax Avoided (all 3 benefits)—
💡 HSA Triple Tax Advantage: (1) Contributions are pre-tax, (2) Growth is tax-free, (3) Withdrawals for medical expenses are tax-free. After 65, withdraw for anything penalty-free (taxed like a Traditional IRA). This is the best account in the tax code.
Tax-Loss Harvesting Calculator
Turn investment losses into tax savings. See how much harvesting a loss is actually worth.
▼
Gains Fully Offset—
Remaining Loss (vs. ordinary income)—
Tax Saved This Year—
Carryforward to Next Year—
💡 You can use up to $3,000 of net capital losses to offset ordinary income each year. Remaining losses carry forward to future years — indefinitely. Beware the wash-sale rule: don't buy the same or substantially identical investment within 30 days of selling.
Standard vs. Itemized Deduction
Should you itemize or take the standard deduction? This calculator gives you the exact answer.
▼
Standard Deduction$32,200
Your Itemized Total—
You Should Take—
Extra Deduction vs. Standard—
Most taxpayers benefit from the standard deduction since TCJA 2017 nearly doubled it. But if you have significant mortgage interest, SALT, and charitable giving, itemizing may save you money.
Marginal vs. Effective Tax Rate
The most misunderstood concept in taxes. Calculate both rates and finally understand the difference.
▼
Taxable Income—
Total Federal Tax—
Marginal Rate (top bracket)—
Effective Rate (actual rate)—
💡 Your marginal rate is only applied to your LAST dollars of income — not your whole paycheck. Most Americans pay a much lower effective rate than their "bracket" suggests. This is why understanding the bracket system matters.
Quarterly Estimated Tax Calculator
Freelancers and self-employed: how much to pay each quarter to avoid IRS penalties.
▼
Estimated Annual Tax—
Safe Harbor Amount (110% prior year)—
Pay Each Quarter (safe harbor)—
Next Due Date—
💡 Safe harbor rule: Pay at least 100% of last year's tax (110% if income over $150K) in quarterly installments and you won't owe a penalty — even if you underpay your current year's actual tax.
State Income Tax Comparator
Thinking of relocating? See the exact tax difference between any two states on your salary.
▼
State Tax in Current State—
State Tax in New State—
Annual Tax Savings—
10-Year Savings (invested at 7%)—
💡 Moving from California to Texas on $120,000 income saves over $15,000/year in state taxes. Invested over 10 years, that's $210,000+ in additional wealth. Tax geography matters enormously.
