How to File Taxes: Step-by-Step Guide

Filing taxes means reporting your income to the IRS using Form 1040 and either claiming a refund or paying what you owe by the April deadline. You'll gather income documents (W-2s, 1099s), choose between the standard deduction or itemizing, calculate your tax liability, and submit electronically or by mail, either yourself with tax software, through a preparer, or via IRS Free File if you qualify.

Section 01

What Documents Do You Need to File Taxes?

You need all income statements received by January 31: Form W-2 from employers, Form 1099-NEC for freelance work over $600, Form 1099-INT for bank interest over $10, Form 1099-DIV for dividends, and Form 1099-K if you received over $5,000 in third-party payment platform transactions (threshold dropped from $20,000 in recent years). Gather receipts for deductible expenses if you plan to itemize—mortgage interest statements (Form 1098), property tax records, charitable donation receipts, medical bills exceeding 7.5% of your adjusted gross income, and state/local tax payments.

Section 02

How Do You Choose Between the Standard Deduction and Itemizing?

Take the standard deduction if your deductible expenses total less than the standard amount—$13,850 for single filers or $27,700 for married filing jointly in 2023 (consult IRS Publication 501 for the current year's figures, as they adjust for inflation). Itemize on Schedule A only if mortgage interest, state and local taxes (capped at $10,000), charitable gifts, and medical expenses above 7.5% of AGI exceed that threshold.

Section 03

What Are the Steps to File Taxes Online Using Tax Software?

Key takeaway

First, create an account with IRS-approved software (TurboTax, H&R Block, TaxAct, FreeTaxUSA, or IRS Free File partners if your AGI is below roughly $79,000—check IRS.gov for the exact threshold). Enter your personal information and filing status, then upload or manually type W-2 and 1099 data.

Section 01

How Do You File Taxes for Free?

Use IRS Free File if your adjusted gross income falls under the program's limit (approximately $79,000 for 2023; verify the current threshold on IRS.gov). Partnering software providers offer fully guided filing at no charge.

Section 02

What Is the Deadline to File Taxes and What Happens if You Miss It?

The federal tax filing deadline is typically April 15, or the next business day if the 15th falls on a weekend or holiday (for example, April 18 in years when the 15th is a Friday and Monday is Emancipation Day in D.C.). If you cannot finish by the deadline, file Form 4868 by that date to get an automatic six-month extension to October 15—no explanation needed, and the IRS grants it automatically.

Section 03

How Do You Submit Your Tax Return to the IRS?

Key takeaway

E-file through tax software, a tax professional, or Free File Fillable Forms; the IRS processes electronic returns faster (refunds in under 21 days) and the error rate is lower than paper. After submitting, you'll receive an email confirmation within 24 hours and can track your refund status using "Where's My Refund?" on IRS.gov or the IRS2Go app, entering your Social Security number, filing status, and exact refund amount.

Section 04

Should You Hire a Tax Preparer or Use Software?

Use software if your return is straightforward—W-2 income, standard deduction, a few kids, maybe student loan interest—and you're comfortable following prompts. Most people pay $0 to $60 for software that handles common situations.

Section 05

What Happens After You File Your Tax Return?

The IRS acknowledges receipt within 24 hours if you e-filed, then begins processing. If you're due a refund and filed electronically with direct deposit, expect the money in your bank account within 21 days; paper returns or refund checks take six to eight weeks.

Key takeaway

Filing taxes is manageable once you gather the right documents and choose a method that fits your situation. For returns involving complex investments, business income, or multi-state filings, consulting a licensed tax professional or enrolled agent ensures compliance and may uncover deductions software alone would miss.

Section 06

FAQ

How much does it cost to file taxes?

IRS Free File is $0 if your AGI is below the program threshold (around $79,000). Basic software costs $0 to $60 for federal filing; state returns may add $15 to $40.

Can I file taxes if I didn't work last year?

Yes, if you had any taxable income—unemployment benefits, investment earnings, gig work, alimony (if the divorce was finalized before 2019)—or if you qualify for refundable credits like the Earned Income Tax Credit or want to claim a recovery rebate credit. Even with zero income, filing can establish a record and protect future Social Security credits if you paid self-employment tax in prior years.

What is the penalty for filing taxes late?

Key takeaway

The failure-to-file penalty is 5% of unpaid tax per month, up to 25%. The failure-to-pay penalty is 0.5% per month, also capped at 25%.

How do I file taxes if I'm self-employed?

Report income on Schedule C (sole proprietor) or Schedule C-EZ (simple business). Deduct ordinary and necessary expenses—home office, supplies, mileage at the IRS standard rate (65.5 cents per mile in 2023, check IRS.gov for the current rate), software, advertising.

Do I need to report income from apps like Venmo or Cash App?

Yes, if you received payments for goods or services totaling $5,000 or more (the threshold recently dropped from $20,000 and 200 transactions). Payment platforms issue Form 1099-K.

What is the difference between a tax credit and a tax deduction?

Key takeaway

A deduction lowers your taxable income; a $1,000 deduction saves you $220 if you're in the 22% bracket. A credit reduces tax owed dollar-for-dollar; a $1,000 credit

Evaluate a side hustle or career income strategy

A side hustle is paid work performed outside a primary job, often as an employee, contractor, seller, or business owner. Before choosing among side hustle ideas, estimate startup costs, ongoing expenses, time requirements, demand, payment terms, and tax responsibilities. Side hustles from home may still require licenses, insurance, secure technology, recordkeeping, or permission under a lease, HOA rule, or local regulation.

Employment income may also grow through additional responsibilities, a promotion, a job change, or improved skills. When learning how to ask for a raise, document relevant duties, results, market information, and the requested change without assuming approval. Update skills to put on resume using accurate examples, and prepare for common interview topics. Compare gross pay, benefits, commuting costs, schedule, stability, and taxes rather than evaluating an opportunity by headline pay alone.
