Last Updated: May 2026
Dividend and investment income
Estimate qualified dividend, interest, NIIT, and state-tax exposure
Model 1099-DIV and 1099-INT income separately from stock-sale proceeds. Qualified dividends and long-term distributions use preferential bands, while interest and ordinary dividends stack into ordinary brackets.
Rule Snapshot: May 2026
Qualified dividends and long-term capital gain distributions use 0%, 15%, and 20% federal rate bands after ordinary taxable income is stacked first. NIIT is estimated at 3.8% on the lesser of net investment income or MAGI above $200,000 single/HOH, $250,000 MFJ/surviving spouse, or $125,000 MFS.

How to Use This Calculator
Start with the taxable income and MAGI you already have before investment income. Then split your investment income into qualified dividends, ordinary dividends, taxable interest, capital gain distributions, and REIT dividends.
Keep asset-sale gains separate. If your question depends on cost basis, sale proceeds, and holding period, use the Capital Gains Tax Calculator instead.
Step 1: Enter your filing status and income stack
Choose filing status, then enter taxable income and MAGI before dividends, interest, and distributions.
Step 2: Split investment income by tax treatment
Enter qualified dividends, ordinary dividends, taxable interest, tax-exempt interest, short-term distributions, long-term distributions, and REIT dividends separately.
Step 3: Add deductions, foreign tax, and state rate
Use the adjustment fields for investment interest deduction, foreign tax paid, and a manual state tax layer when applicable.
Step 4: Review the federal, NIIT, and state layers
Compare ordinary-rate tax, preferential dividend tax, NIIT, state tax, and after-tax investment income.
How the Dividend and Investment Income Tax Calculator Works
The calculator separates ordinary investment income from preferential investment income. Ordinary dividends, taxable interest, short-term distributions, and REIT dividends are added to the ordinary income stack. Qualified dividends and long-term capital gain distributions are then layered into the preferential 0%, 15%, and 20% bands.
When NIIT is turned on, the calculator estimates the 3.8% surtax on the lesser of net investment income or MAGI above the filing-status threshold. Foreign tax paid is treated as a simplified credit against regular federal investment-income tax, not against NIIT.
| Income type | Modeled treatment | Planning note |
|---|---|---|
| Qualified dividends | Preferential 0%, 15%, or 20% federal bands | Stacked after ordinary taxable income. |
| Ordinary dividends | Ordinary income-tax brackets | Use for non-qualified dividends or the ordinary portion of 1099-DIV income. |
| Taxable interest | Ordinary income-tax brackets | Includes bank interest, CD interest, corporate bonds, and many Treasury interest scenarios. |
| Long-term capital gain distributions | Preferential 0%, 15%, or 20% federal bands | Useful for mutual fund or ETF capital gain distributions reported on tax forms. |
| Short-term capital gain distributions | Ordinary income-tax brackets | Modeled as ordinary investment income. |
| REIT dividends | Usually ordinary income in this calculator | Enter any confirmed qualified portion in the qualified dividend field instead. |
Dividend Tax, Interest Tax, NIIT, and 1099 Investment Income
Dividend Income Is Not One Tax Category
A 1099-DIV can include ordinary dividends, qualified dividends, capital gain distributions, Section 199A dividends, foreign tax paid, and other details. Treating all of that as one dividend-tax rate can be misleading because each line can enter the return differently.
Qualified dividends and long-term capital gain distributions use 0%, 15%, and 20% federal rate bands after ordinary taxable income is stacked first. Ordinary investment income stays in ordinary brackets. That split is the reason this page exists as a separate workflow from a basic capital gains calculator.
When To Use This Page Instead Of Capital Gains
| Tool | Best for | Use when |
|---|---|---|
| Dividend and investment income calculator | 1099-DIV, 1099-INT, dividends, interest, fund distributions, foreign withholding, NIIT | Use when the income appears on tax forms without a separate sale proceeds and basis calculation. |
| Capital gains tax calculator | Asset sale proceeds, cost basis, holding period, gain/loss amount, sale timing | Use when you sold or may sell a stock, fund, crypto, property, or other asset. |
| Taxable income calculator | AGI, standard deduction, itemized deductions, QBI, senior deduction, taxable income | Use before this page when you need to build the taxable-income stack from scratch. |
NIIT and Foreign Dividend Withholding
NIIT can add a separate 3.8% layer when modified adjusted gross income exceeds the filing-status threshold. This calculator keeps NIIT visible because high-income investors often miss it when they only apply the qualified dividend rate.
Foreign tax paid is different. The calculator includes a simplified foreign tax credit input so users can see how dividend withholding may reduce regular federal tax. The actual credit can require Form 1116 limits, treaty details, passive income baskets, and carryovers, so final filing can differ.
Practical Planning Uses
- Estimate tax before shifting from growth funds to dividend-heavy funds.
- Compare tax cost of qualified dividends versus taxable interest income.
- Check whether a high-income year creates NIIT exposure.
- Model a simple foreign dividend withholding scenario before filing.
- Layer in a state-tax estimate when your state taxes dividends or interest.
