The Formula Explained

Taxable income (estimate mode): \( \mathrm{MD\ AGI} = \max(0, \mathrm{Gross} - \mathrm{PreTax}) \) \( \mathrm{StdDeduction} = \min(\max(0.15 \times \mathrm{MD\ AGI},\ D_{\min}),\ D_{\max}) \) \( \mathrm{Taxable} = \max(0, \mathrm{MD\ AGI} - \mathrm{Deduction} - \mathrm{Exemptions}) \) Maryland state tax (piecewise by filing status s with brackets i): \( \mathrm{StateTax} = \sum_i \left( \min(\max(0, x - L_i),\ U_i - L_i) \times r_i \right) \) where x = Taxable, [L_i, U_i) are bracket bounds, and r_i the rate. Local tax (flat on taxable): \( \mathrm{LocalTax} = x \times \frac{r_{\text{local}}}{100} \) Totals and rates: \( \mathrm{Total} = \mathrm{StateTax} + \mathrm{LocalTax} \) \( \mathrm{EffRate_{taxable}} = \frac{\mathrm{Total}}{x} \)

Glossary of Variables

  • Gross income: Total annual income before taxes and pre-tax deductions.
  • Pre-tax deductions: Contributions that reduce taxable wages (e.g., 401(k), HSA, FSA).
  • Maryland AGI (approx.): Gross income minus pre-tax deductions (simplified for estimation).
  • Deduction: Either Maryland standard deduction (15% with filing-status min/max) or your itemized amount.
  • Personal exemptions: Maryland exemptions (AGI-limited). Enter total amount if known.
  • Maryland taxable income: Income subject to Maryland state and local tax.
  • State income tax: Tax computed using Maryland's progressive brackets for your filing status.
  • Local income tax: County/city rate applied as a flat percentage to Maryland taxable income.
  • Total MD income tax: Sum of state and local income tax.
  • Effective tax rate: Total Maryland tax divided by Maryland taxable income (or gross income for planning).
  • Marginal state rate: The top state bracket rate that applies to your last dollar of taxable income.

How It Works: A Step-by-Step Example

Scenario: Single filer in 2024, gross income $80,000, pre-tax deductions $5,000, standard deduction, local rate 3.20%.

  1. MD AGI ≈ 80,000 − 5,000 = $75,000.
  2. Standard deduction = 15% × 75,000 = 11,250, capped at Single max $2,400 ⇒ $2,400.
  3. Assume exemptions = $0. Taxable = 75,000 − 2,400 = $72,600.
  4. State tax (Single brackets, 2024):
    • 2% of first $1,000 = $20
    • 3% of next $1,000 = $30
    • 4% of next $1,000 = $40
    • 4.75% of remaining $69,600 = $3,306.00
    State total = 20 + 30 + 40 + 3,306.00 = $3,396.00
  5. Local tax = 72,600 × 3.20% = $2,323.20
  6. Total MD tax = 3,396.00 + 2,323.20 = $5,719.20
  7. Effective (of taxable) = 5,719.20 / 72,600 ≈ 7.88%

Frequently Asked Questions (FAQ)

Which filing statuses are supported?

Single, Married Filing Jointly, Married Filing Separately, Head of Household, and Qualifying Widow(er). Bracket thresholds follow Maryland 2024 rules for these categories.

Does local tax have brackets?

No. Maryland local income tax is a flat percentage of your Maryland taxable income determined by your county/city of residence.

How is the Maryland standard deduction calculated?

It equals 15% of income subject to Maryland tax, subject to filing-status minimums and maximums (2024: Single/MFS $1,600–$2,400; MFJ/HOH/QW $3,200–$4,800).

Can I enter itemized deductions?

Yes. Switch to “Use itemized amount” in Estimate mode and enter your Maryland itemized deductions.

Why does my result differ from my actual tax?

Real returns may include credits, subtractions, exemptions phaseouts, and other adjustments not modeled here. Use your latest instructions or consult a tax professional.

Where can I find my county’s rate?

Visit the Maryland Comptroller’s website for current local income tax rates and confirm your county/city percentage for the tax year in question.
