Tips by Filer Type
1First-Time Filers
Gather all your documents first: W-2s from employers, 1099s for any other income, Social Security number, bank account info for direct deposit
Start with Cash App Taxes or FreeTaxUSA if you want free filing with no surprises
Most first-time filers have simple returns (W-2 only) and qualify for any free option
Check if you qualify for the Earned Income Tax Credit (EITC), even with modest income
E-file and choose direct deposit to get your refund in about 21 days
2Families
Child Tax Credit: $2,000 per qualifying child under 17. Up to $1,700 is refundable for 2025
Child and Dependent Care Credit: up to $3,000 for one qualifying individual, $6,000 for two or more (20-35% of expenses depending on income)
EITC: up to $7,830 for three or more qualifying children. The credit phases out at higher incomes. Even if you think you earn too much, check the tables
Dependent Care FSA: if your employer offers it, you can exclude up to $5,000 from taxable income for child care expenses
American Opportunity Credit: up to $2,500 per student for the first four years of higher education
3Self-Employed and Freelancers
Track all business expenses throughout the year. Mileage, home office, supplies, software subscriptions, and professional development are all deductible
Home office deduction: simplified method is $5/sq ft up to 300 sq ft ($1,500 max). Actual method can be higher but requires detailed records
SEP IRA contributions are deductible and due by your filing deadline (including extensions). Contribute up to 25% of net self-employment income or $69,000
Quarterly estimated taxes: pay by April 15, June 15, September 15, and January 15 to avoid underpayment penalties
Use Cash App Taxes (free) or FreeTaxUSA (free federal) for Schedule C filing. Do not pay $159 for TurboTax Self-Employed

4Retirees
Social Security taxation: up to 85% of benefits may be taxable depending on combined income. Single filers: above $25,000 some benefits are taxed, above $34,000 up to 85% is taxed
Required Minimum Distributions (RMDs): if you are 73 or older, you must take RMDs from traditional IRAs and 401(k)s. Missing the deadline results in a 25% excise tax on the amount not withdrawn
Medicare premiums: Part B and Part D premiums may be deductible as medical expenses if you itemize and total medical expenses exceed 7.5% of AGI
Extra standard deduction: if you are 65+ or blind, you get an additional $1,950 (single) or $1,550 (married) on top of the regular standard deduction
TCE/AARP Tax-Aide program: free in-person tax help for taxpayers 60 and older. Volunteers specialize in retirement income issues
Commonly Missed Deductions
Student loan interest
Deduct up to $2,500 in student loan interest paid, even if you take the standard deduction. Phases out at higher incomes.
Educator expenses
Teachers can deduct up to $300 for unreimbursed classroom supplies. Both spouses can claim $300 each if both are educators.
IRA contributions
Traditional IRA contributions may be deductible. $7,000 limit ($8,000 if 50+). Deadline is April 15 for tax year 2025.
State sales tax
If you live in a no-income-tax state, you can deduct state sales tax instead of state income tax on Schedule A (subject to $10,000 SALT cap).
Charitable contributions
Cash donations to qualified charities are deductible if you itemize. Keep receipts for donations over $250. Non-cash donations (clothing, furniture) also count.
Medical expenses
Medical expenses exceeding 7.5% of your AGI are deductible if you itemize. This includes insurance premiums, prescriptions, dental, vision, and certain travel for medical care.
Cannot File by April 15?
File Form 4868 by April 15 for an automatic six-month extension (new deadline: October 15, 2026). This extends your time to file but does not extend your time to pay. If you owe taxes, estimate and pay by April 15 to avoid penalties and interest.
Most free tax software can file Form 4868 electronically. Cash App Taxes and FreeTaxUSA both support extension filing.
How to Get Your Refund Fastest
E-file your return
E-filed returns are processed much faster than paper returns.
Choose direct deposit
Refunds deposited directly to your bank account arrive in about 21 days. Paper checks take 6-8 weeks.
File accurately
Errors delay processing. Double-check Social Security numbers, bank routing numbers, and math.
Do not file too early
Wait until you have received all W-2s and 1099s. Filing with incorrect info causes delays.
Track your refund
Check status at IRS.gov/refunds (Where's My Refund tool) or the IRS2Go mobile app.
