Tax Season Preparation Checklist: Get Organized Before You File

Income documents

Tax documents start arriving in late January and early February. Create a folder (physical or digital) and collect these as they arrive:

Income documents: W-2 from each employer (wages and salary), 1099-NEC (freelance or contract income over $600), 1099-K (payment platform income over $600), 1099-INT (bank interest over $10), 1099-DIV (investment dividends), 1099-B (investment sales), 1099-R (retirement distributions), 1099-G (unemployment compensation or state tax refunds), 1099-SA (HSA distributions), and Schedule K-1 (partnership or S-corp income).

Deduction and credit documents: Form 1098 (mortgage interest), Form 1098-T (college tuition), Form 1098-E (student loan interest), Form 1095-A (health insurance marketplace), property tax statements, and charitable donation receipts.

Do not file too early. Wait until you have received all expected documents. Filing with incomplete information leads to amended returns and delays. Most forms arrive by mid-February, though some K-1s and corrected forms may take until March.

Compare to last year's return.

Compare to last year's return. Pull up your prior year tax return and check for items you might forget: recurring deductions (charitable giving, student loan interest), credits (education credits, child tax credit), and income sources (bank interest, dividends) that generate tax documents.

Check for missing documents. If an expected W-2 or 1099 has not arrived by mid-February, contact the issuer. You can also check your IRS account at irs.gov for wage and income transcripts showing what has been reported to the IRS under your Social Security number.

Organize deduction records: Sort charitable donation receipts by organization and amount. Tally medical expenses to see if they exceed 7.5% of your adjusted gross income (the threshold for deducting). Compile business expense records if you are self-employed. Gather home office measurements and utility records if claiming the home office deduction.

Review life changes from the past year: Marriage, divorce, new baby, home purchase, job change, retirement account distributions, starting a business, or moving all affect your tax return. Note any changes to discuss with your tax preparer or to address in your filing software.

Add up your potential itemized deductions

Before filing, estimate whether itemizing or taking the standard deduction saves you more. The 2025 standard deduction is $15,000 (single), $22,500 (head of household), or $30,000 (married filing jointly).

Add up your potential itemized deductions: Mortgage interest (Form 1098) + state and local taxes paid (up to $10,000 SALT cap) + charitable contributions + medical expenses above 7.5% of AGI + any other qualifying deductions.

If itemized total exceeds standard deduction: Itemize on Schedule A. Your tax software calculates this automatically, but knowing in advance helps you ensure you have all necessary documentation.

If itemized total is close to the standard deduction: Consider bunching strategies — timing charitable donations or other deductible expenses so they fall in alternating years, allowing you to itemize in high-expense years and take the standard deduction in low-expense years.

Earned Income Tax Credit (EITC)

Tax credits are more valuable than deductions because they reduce your tax dollar-for-dollar. Review whether you qualify for these commonly missed credits:

Earned Income Tax Credit (EITC): For low-to-moderate income workers. Worth up to $7,830 with three or more children (2025). Income limits vary by filing status and number of children. Many eligible taxpayers do not claim it.

Child Tax Credit: $2,000 per qualifying child under 17. Partially refundable ($1,700 max refund portion). Phases out at $200,000 single/$400,000 married income.

American Opportunity and Lifetime Learning Credits: For college tuition and education expenses. AOTC is worth up to $2,500 per student for the first four years. Lifetime Learning is up to $2,000 for any post-secondary education.

Saver's Credit: 10-50% credit on up to $2,000 in retirement contributions for low-to-moderate income filers. Worth up to $1,000 ($2,000 married).

Energy credits: Up to $3,200 for home energy improvements and 30% of solar panel costs (no cap). These do not require itemizing.

Child and Dependent Care Credit: 20-35% of up to $3,000 in child care expenses ($6,000 for two or more children).

Filing deadline

Filing deadline: April 15 for most taxpayers. If April 15 falls on a weekend or holiday, the deadline moves to the next business day. Maine and Massachusetts residents get until April 17 some years due to Patriots' Day and Emancipation Day holidays.

Extension option: File Form 4868 by April 15 for an automatic 6-month extension to October 15. An extension gives you more time to file but NOT more time to pay — any taxes owed are still due April 15. Estimated payments with the extension avoid penalties and interest.

Free filing options: IRS Free File (AGI under $84,000), Cash App Taxes (free for all), IRS Direct File (expanding to more states), and VITA sites (income under $67,000).

When to hire a professional: Consider a CPA or enrolled agent if you are self-employed with significant business expenses, have rental income, sold investments or property, received foreign income, or are going through major life changes like divorce or inheritance.

Adjust your W-4

Adjust your W-4: If you owed a large amount or received a big refund, update your W-4 with your employer. Use the IRS Tax Withholding Estimator to dial in the right withholding for the coming year.

Review retirement contributions: Tax season is a natural time to evaluate whether you are maximizing tax-advantaged accounts. Increase your 401(k) or IRA contributions if possible.

Set up a system for the coming year: Create a tax folder, start tracking deductible expenses from January, use accounting software if self-employed, and save receipts for charitable donations as you make them throughout the year.

Store your return securely: Keep copies of your tax return and supporting documents for at least 3 years (7 years if you have unreported income over 25% of gross income). Digital storage is fine — just ensure it is backed up and secure.
