Maryland Standard Deduction 2025 Guide – The Maryland standard deduction for 2025 has undergone significant changes that could lower your state income tax bill. Whether you’re a full-year resident, part-year resident, or filing as a nonresident with Maryland-source income, understanding the updated rules is essential for accurate filing in 2026.
This comprehensive guide covers the exact 2025 amounts, how the deduction works, key changes from prior years, comparisons to the federal standard deduction, and practical tips for Maryland taxpayers.
What Is the Maryland Standard Deduction for 2025?
The Maryland standard deduction is a fixed reduction from your Maryland adjusted gross income (MAGI) that lowers your taxable income at the state level. Unlike federal rules, Maryland’s standard deduction is separate and does not automatically match the IRS amount.
Maryland requires that your income and deductions align with your federal return in specific ways: you can only itemize on your Maryland return if you itemized on your federal return. If you took the federal standard deduction, you must use Maryland’s standard deduction.
Maryland Standard Deduction 2025 Amounts by Filing Status
For tax year 2025 (returns filed in 2026), the standard deduction is now a flat amount with no income-based phase-in:
- Single, Married Filing Separately, or Dependent filers: $3,350
- Married Filing Jointly, Head of Household, or Qualifying Surviving Spouse filers: $6,700
These amounts apply uniformly regardless of your income level. Future years will see cost-of-living adjustments (COLA) indexed increases.
Quick Reference Table:
| Filing Status | 2025 Standard Deduction |
|---|---|
| Single | $3,350 |
| Married Filing Separately | $3,350 |
| Dependent | $3,350 |
| Married Filing Jointly | $6,700 |
| Head of Household | $6,700 |
| Qualifying Surviving Spouse | $6,700 |
For part-year residents, prorate the standard deduction using your Maryland income factor (Maryland taxable income divided by federal AGI).
How the Maryland Standard Deduction Changed in 2025?
The 2025 legislative session (via the Budget Reconciliation and Financing Act) dramatically simplified and increased the deduction:
- Eliminated the old income-based formula (previously 15% of MAGI with minimums/maximums).
- Removed phase-in based on adjusted gross income.
- Increased amounts for all filers (e.g., single filers saw a jump from prior maximums around $2,250–$2,800).
- Added automatic future COLA indexing.
These changes make planning easier and provide meaningful relief for most Maryland taxpayers.
Maryland vs. Federal Standard Deduction: Key Differences in 2025
The federal standard deduction for 2025 is significantly higher:
- Single or Married Filing Separately: $15,750
- Married Filing Jointly or Qualifying Surviving Spouse: $31,500
- Head of Household: $23,625
- Additional amounts for those age 65+ or blind
Important Maryland rule: If you claim the federal standard deduction, you cannot itemize on your Maryland return—you must use the state standard deduction. This decoupling means many filers will automatically take Maryland’s smaller flat amount unless they itemize federally.
Who Can Claim the Maryland Standard Deduction?
Most Maryland residents and part-year residents qualify. Nonresidents with Maryland-source income may also claim a prorated portion on Form 505.
Exclusions and notes:
- Fiduciaries generally cannot use it.
- Dependents follow the $3,350 amount.
- Military personnel and special situations may have additional worksheets.
Always check your federal AGI for personal exemption phase-outs, which interact with overall tax calculations.
When Should You Take the Standard Deduction vs. Itemizing in Maryland?
Compare both options on your Maryland Form 502:
- Use the standard deduction if your allowable itemized deductions (after any phase-out) are lower than the flat amount above.
- Itemize only if you itemized on your federal return and your Maryland itemized total (minus state/local taxes with SALT limits) exceeds the standard deduction after phase-out.
Pro tip: Run both calculations—many high-income filers will find the standard deduction more beneficial due to the new phase-out rules.
New Itemized Deduction Phase-Out Rules for 2025
Starting in 2025, high earners face a new limitation on itemized deductions:
- Phase-out begins at federal AGI over $200,000 ($100,000 if Married Filing Separately).
- Reduce itemized deductions by 7.5% of the excess AGI.
- “Breakeven” points (where itemizing no longer beats the standard deduction) vary by filing status and income.
Examples of breakeven points (approximate, from official guidance):
- Single filer at $250,000 FAGI: Itemized must exceed ~$7,100 pre-phase-out.
- Married Filing Jointly at $400,000 FAGI: Itemized must exceed ~$21,700 pre-phase-out.
Use the Itemized Deduction Worksheet (14A) in the Resident Booklet to calculate.
