Last-Minute 2025 Individual Tax Filing Checklist: What Maryland Taxpayers Should Pull Together Before They File

• • Why March Can be a Good Time to Get Your Tax Documents in Order

    By March, most 2025 tax forms should have arrived, and the April 15, 2026 filing deadline is in clear view. Rushing at the last second is when people overlook income, miss deductions, or forget about Maryland-specific items that could change their bottom line.

     

    A calm, structured checklist gives you two advantages:

    • You reduce the risk of IRS or Maryland notices because income and withholding are fully reported.
    • You walk into a meeting with AllTax—or log in to your portal—confident that you’ve already gathered what’s needed.

     

    Use the sections below as a practical roadmap. You don’t need every item on this list, but you should consider each one.

  •  

  • ✅Step 1: Gather Your Income Documents

     

  • Start with anything that reports income for 2025. Common items include:

    • - W-2s from each employer for you (and your spouse, if filing jointly).
    • - 1099-NEC or 1099-MISC for freelance, contractor, or side gig work.
    • - 1099-K for payment platform income (PayPal, Venmo, Cash App, eBay, etc.), if issued.
    • - 1099-INT and 1099-DIV for bank interest, CDs, and dividends.
    • - 1099-B and year-end brokerage tax reports for investment sales.
    • - 1099-R for IRA, pension, or retirement plan distributions.
    • - SSA-1099 for Social Security benefits.
    • - 1099-G for unemployment benefits or state tax refunds.
    • - K-1s from partnerships, S corporations, or estates/trusts.
    • - Rental income summaries and supporting reports if you own rental property.

     

    For Maryland residents, remember to include income from all states where you worked or earned income. AllTax will help you sort out which portions are taxed by Maryland and whether any credits apply.

  • ✅Step 2: Pull Deductions and Credit-Related Records

    Next, gather information that might support deductions, adjustments, or credits. Even if you end up taking the standard deduction, it’s helpful for your tax professional to see the full picture.

     

    Consider:

    • Home ownership
      • - Form 1098 for mortgage interest.
      • - Real estate tax bills and proof of payment.
      • - Records of points paid to refinance in 2025.
    • Charitable contributions
      • - Receipts or annual statements from qualified charities.
      • - Documentation for non-cash donations (clothing, household goods), ideally with estimated values.
    • Medical and health-related expenses
      • - Out-of-pocket medical, dental, and vision costs not reimbursed by insurance.
      • - Health insurance premiums you paid personally (outside of an employer plan).
      • - HSA contributions (often reported on Form 5498-SA) and any distributions.
    • Education expenses
      • - Form 1098-T from colleges or universities.
      • - Records of tuition, fees, and required course materials.
      • - Student loan interest (Form 1098-E).
    • Child and dependent care
      • - Amounts paid for daycare, after-school care, or summer camps that qualify.
      • - Provider name, address, and tax ID number (or Social Security number for an individual provider).
    • Retirement contributions
      • - 2025 contributions to traditional IRAs (even if made in early 2026 but designated for 2025).
      • - Workplace plan summaries if you made after-tax or Roth contributions.
    • State and local taxes
      • - Maryland estimated tax payments made during 2025.
      • - Any 2024 Maryland balance-due payment made in 2025.

     

    Bring everything, even if you’re not sure it “counts”—AllTax can help decide what’s deductible or credit-eligible.

  •

    ✅Step 3: Think Through 2025 Life Changes

    Major life events often change your tax picture. Make a short list of anything that happened in 2025 that might be relevant, such as:

    • - You got married, divorced, or legally separated.
    • - You had a child, adopted, or now support a dependent relative.
    • - A child turned 19 (or 24 if a full-time student) and may no longer qualify for certain credits.
    • - You moved into or out of Maryland, or changed Maryland counties.
    • - You started, sold, or closed a small business or side gig.
    • - You exercised stock options or received equity-based compensation.
    • - You inherited assets, received a major gift, or sold inherited property.

     

    Jotting these changes down in advance helps your tax professional ask better questions and identify planning opportunities you might otherwise miss.

  •  

  •  

    ✅Step 4: Organize and Sanity-Check Before You Share

    Once you’ve gathered documents, take a few minutes to organize and do a quick “reasonableness” review:

    • - Group documents by type (income, deductions, credits) or by taxpayer (you, spouse, dependents).
    • - Compare to last year’s return: Are any major income sources or deductions missing this year? If something disappeared or appeared for the first time, make a note.
    • - Highlight anything unusual, such as one-time income, large charitable gifts, or a big spike in medical costs.
    • - If sharing documents electronically, use clear file names (for example, 2025-W2-EmployerName-YourName.pdf).

     

    A little structure makes it easier for AllTax to review your situation thoroughly and reduces back-and-forth during busy season.

  •  

  •  

    ✅Step 5: Decide Whether to File Now or Extend

    As you get organized in March, you may realize you’re still missing key items—such as a late-arriving K-1, brokerage corrected 1099, or documentation for a complex transaction.

     

    Rather than rushing and risking errors, it can be smarter to:

    • - File an extension to give yourself and AllTax more time to file an accurate return.
    • - Estimate and pay what you reasonably expect to owe by April 15, 2026, to minimize penalties and interest.

     

    An extension buys time to file; it does not extend the time to pay. AllTax can help you understand whether you’re on track, and whether an extension makes sense for your situation.

    How AllTax Accounting Can Help:

    You don’t have to perfect this checklist before you reach out. Bring what you have, and AllTax can:

    •  • Identify which documents you’re still missing and which ones may not be necessary.
    •  • Spot deductions, credits, and Maryland-specific items that often get overlooked.
