Maryland Capital Gains Tax Calculator

Maryland taxes capital gains as ordinary income under a graduated progressive bracket schedule, with marginal statutory rates ranging from 2.00% up to a top marginal rate of 6.50%.

Capital gains get evaluated alongside other taxable earnings across Maryland's progressive tax brackets. When gains are recognized on top of baseline salary or business income, they're taxed at the taxpayer's top marginal bracket rate, reaching up to 6.50%.

Maryland taxes a capital gain as ordinary income on a ten-band schedule topping out at 6.50%, after the Budget Reconciliation and Financing Act of 2025 added 6.25% and 6.50% bands above $500,000 and $1,000,000. The rate below is only part of the bill: every Maryland county and Baltimore City levies a local income tax on the same base, which this calculator does not include, so a resident should expect the true burden on a gain to be meaningfully above the state figure shown.

The gain is stacked on top of your other income and walked through the bands from there.

Step by step, with your numbers:

1. Start with the net gain. Capital losses and loss carryforwards are netted against the gain before anything else happens.
2. Stack the gain on your other income. Ordinary income fills the lower brackets first and the gain sits on top of it, so the gain is taxed at whatever rates are still open above your salary. The same gain costs a high earner more than it costs a low earner. Enter other income as a taxable-income figure: the calculator does not subtract a standard deduction or personal exemption for you.
3. Walk the brackets. The slice of the gain that falls in each band is multiplied by that band's rate, and the pieces are added together.
4. Effective rate. Total Maryland tax divided by the whole realized gain. On a graduated schedule this sits below the top marginal rate, because the lower slices were taxed at lower rates.
5. Net proceeds. Subtract the state tax from the gain to get what you keep before federal tax.

Consider an investor in Maryland who realizes $100,000 in capital gains on top of $75,000 in baseline ordinary income for the year.

1. Stack the income. Maryland taxes capital gains as ordinary income. Since income fills the lower brackets first, the $75,000 of baseline income already occupies the lower tiers, so the $100,000 gain stacks on top and pushes into higher brackets.
2. Apply the marginal brackets. Working through Maryland's bracket schedule, each slice of the gain is taxed at its own bracket's rate, with the highest slice reaching the 5.50% top marginal bracket.
3. Total state tax due. Summing the tax owed across every bracket the gain touches produces a total Maryland state tax liability of $5,125.00.
4. Effective rate. Dividing that liability by the $100,000 gain gives an effective rate of 5.13%, lower than the 5.50% marginal bracket since only the top slice of the gain is taxed at that rate.
5. Net proceeds. After paying $5,125.00 in state tax, the investor keeps $94,875.00 of the $100,000 gain, before any federal tax applies.

Maryland's schedule has more bracket edges than any other state in this set, and because the gain stacks on other income each edge sits at a different gain figure for every taxpayer. At the calculator's $75,000 of other income, the edges land at gains of $25,000, $50,000, $75,000, $175,000, $425,000 and $925,000.

The threshold walk. Take the $150,000 edge, where Maryland steps from 5.25% to 5.50%. At a gain of $75,000 on $75,000 of other income the computed tax is $3,750.00. At a gain of $75,100, one hundred dollars later, it is $3,755.50. That last hundred dollars of gain cost $5.50 where the hundred before it cost $5.25. The same shape repeats at every edge: at a gain of $25,000 the tax is $1,187.50 and at $25,100 it is $1,192.50, a step from 4.75% to 5.00% on the marginal dollar. At the top edge, a gain of $925,000 produces $54,875.00 and $926,000 produces $54,940.00, meaning that $1,000 cost $65.00 rather than the $62.50 it would have cost just below.

The marginal cost of the next unit. At the $100,000 baseline gain, each additional $1,000 of gain costs $55.00: the engine returns $5,125.00 at $100,000 and $5,180.00 at $101,000. Push the gain to $175,000 and the next $1,000 costs $57.50; at $425,000 it costs $62.50. There is no point in Maryland's schedule where an extra dollar of gain is free, because the 2.00% band is exhausted by the first $1,000 of anyone's income.

The reverse question. How much gain can be realised before crossing into the next band? On $75,000 of other income, $25,000 of gain is the last dollar taxed entirely at 4.75%, and the engine confirms the flat 4.75% effective rate there. The next stopping points are $50,000 (still all at or below 5.00%, tax $2,437.50), $75,000 ($3,750.00) and $175,000 ($9,250.00). Splitting a $200,000 disposition into a $175,000 sale this year and the remainder next year keeps the whole of the first tranche out of the 5.75% band, which is worth $6.25 per $1,000 shifted.

Filing status moves the whole sweep. The same $100,000 gain on $75,000 of other income costs $5,125.00 single and $4,812.50 married filing jointly, a difference of $312.50, because the joint schedule widens the 4.75% band to $150,000 rather than $100,000.

What the sweep leaves out, and it is large. The engine walks the state schedule only. Every Maryland county and Baltimore City levies a local income tax on the same base at 2.25% to 3.30% for 2026, and no code path in this calculator applies it. There is also a separate 2% Maryland surtax on net capital gains where federal AGI exceeds $350,000, which is likewise absent. On the $500,000 gain scenario, where the engine reports $28,312.50, a Montgomery County resident's true state-plus-local bill would be materially higher, and the calculator cannot quantify it.

While this calculator provides penny-exact state statutory modeling, additional federal and transactional complexities warrant supplementary review: - Federal Capital Gains Taxes: Federal long-term brackets (0%, 15%, 20%) and short-term ordinary rates up to 37% under IRC § 1. - Net Investment Income Tax (NIIT): The 3.8% surtax on net investment income under IRC § 1411 for single filers over $200,000 (married joint over $250,000). - Alternative Minimum Tax (AMT): Federal AMT calculations under IRC § 55 impacting incentive stock option (ISO) exercise spread. - Section 1031 Like-Kind Exchanges: Tax deferral mechanisms for real property held for productive use in trade, business, or investment. - Qualified Small Business Stock (QSBS): Federal Section 1202 gain exclusions where state conformity varies significantly.

• Assuming Federal Rate Parity: Most states do not offer preferential long-term capital gains rates; gains are taxed at standard ordinary income rates.
• Failing to Track Holding Periods: Short-term gains (assets held ≤1 year) generate higher federal tax liabilities even if state rates treat both holding periods identically.
• Underestimating Multi-State Apportionment: Selling real estate or business assets located in other jurisdictions triggers multi-state non-resident return filing obligations.
• Neglecting Underpayment Penalties: Substantial one-time liquidity events require prompt estimated tax payments within the quarter of sale to avoid statutory penalties.
• Mismatched Cost Basis Records: Failure to document reinvested dividends, stock splits, or structural return-of-capital distributions leads to inflated taxable gain calculations.
