How To File Your Taxes: Step-by-Step Guide

Learning how to file your taxes can feel overwhelming at first, and mistakes can be costly. But with a little organization and the right tools, the process becomes much more manageable. This guide walks you through what documents you need and how to file accurately to avoid delays or penalties.

Quick Take

• You’ll need income forms, personal information, prior-year tax details, deduction records and banking information to get started.

• You can file your taxes using tax software, IRS Free File, paper forms or with help from a tax professional.

• Enter your income, deductions and credits carefully to avoid errors and delays.

• Review your return before submitting and pick e-file for faster processing.

• Pay any taxes owed or use “Where’s My Refund?” to track your refund.

Step 1: Gather Your Tax Documents

Before you begin filing, gather the following documents:

Income Forms

• W-2 forms from employers

• 1099 forms for contract work, investments or other income

Deduction and Credit Documents

• Childcare expenses

• Dependent care expenses

• Health savings account (HSA) or flexible spending account (FSA) contributions

• Retirement contributions

• Home mortgage and property tax payments, if you itemize

• Charitable donations, if you itemize

• Qualifying healthcare expenses, if you itemize

Social Security Numbers and Prior-Year Return

• Social Security numbers for you and all dependents

• Previous year’s tax return for adjusted gross income (AGI) and exact refund amount

Bank Information for Refund

• Bank account and routing numbers to receive any tax refund via direct deposit or to pay amounts owed

Step 2: Choose How You’ll File

You have several options for filing your taxes — including free and easy methods depending on your situation.

Tax Software

Popular platforms like TurboTax, H&R Block and TaxAct offer user-friendly software that guides you through the filing process, providing real-time calculations and error checking. Some offer free versions for simple returns up to a set income limit.

IRS Free File

If your AGI is $89,000 or less, you can use IRS Free File, which partners with tax software companies to provide free filing services. This option offers the same features as paid software without the cost.

Paper Forms

For those comfortable with tax terminology, the IRS offers fillable forms online. This option is completely free but provides no guidance – you’ll need to know which forms to file and how to complete them correctly.

Tax Professional

Certified public accountants (CPAs) and tax preparers can help with complex tax situations, such as business income, multiple income sources or major life changes. They can provide personalized advice and handle complicated deductions.

Step 3: Enter Your Income and Adjustments

After choosing how to file, the next step is entering your financial information into your return.

Report All Income

Before filing, make sure you have the following ready:

• W-2s: Wages from employers

• 1099s: Includes wages from freelance or independent contractor work

You must file a tax return if you have over $400 in net earnings from self-employment or if you meet gross income filing requirements.

Standard vs. Itemized Deduction

Whether you choose the standard or itemized deduction will depend on which results in a lower taxable income.

• Most filers take the standard deduction, which is a fixed amount based on their filing status.

• Itemized deductions are when you claim certain deductions, such as state and local income taxes, mortgage interest and charitable donations.

Tax Credits

Tax credits directly reduce the amount of tax you owe and may increase your refund. Tax credits include earned income tax credit (EITC), child tax credit (CTC) and the American opportunity tax credit (AOTC).

Step 4: Review and Submit Your Return

Before submitting, double-check all entries on your estimated tax return – small errors can delay your refund. Verify that:

• All income is reported

• Social Security numbers are correct

• Deductions are properly documented

• Banking information is accurate

When you’re ready, submit it electronically for faster processing. You should receive confirmation when your tax return is accepted.

Step 5: Pay or Track Your Refund

If you owe money to the IRS, you can pay with your bank account, a debit or credit card or a digital wallet. Other ways to pay include the following:

• Same-day wire

• Mailing a check or money order

• Paying cash via a retail partner

If you need more time to pay, you can request a payment plan. The IRS offers both long- and short-term plans.

After 24 hours, you can start tracking your refund with the “Where’s My Refund?” tool. Most refunds are issued within 21 days if you e-file and opt for direct deposit.

Common First-Time Filing Mistakes

Tax filing mistakes can cause your tax return to be delayed or rejected. Here are some common ones, according to the IRS.

• Filing too early: Filing your return before you receive all W-2s and 1099s can cause your tax return to be inaccurate or incomplete.

• Social Security number mistakes: Refer to your Social Security card when entering Social Security numbers on a tax return to avoid missing or inaccurate numbers.

• Name mistakes: Your name and the names of your dependents should match each person’s name on their Social Security card.

• Inaccurate information: If there are inaccuracies related to income, filing status, deductions or credits, the IRS will likely require you to file an amended return.

• Math errors: Using tax prep software removes the possibility of math errors, but those who file paper returns may make mistakes when calculating.

• Incorrect banking information: The IRS encourages filers to choose direct deposit for refunds because it’s the quickest way to receive the money. Unfortunately, some taxpayers make mistakes when entering bank routing or account numbers.

• Missing signatures: Tax returns require the signatures of the main parties listed unless there is an exception, such as a military member who has a valid power of attorney. If a signature is missing, the tax return will be invalidated.

Key Tax Deadlines To Know

Keep these dates in mind when filing your taxes:

Keep In Mind

Requesting a tax extension to file is not an extension to pay. You will still owe any taxes due by the April 15 filing deadline. You can request a payment plan, but penalties and interest will apply.

Key Takeaways

• Gather your income forms, personal details, prior-year tax information and deduction records before starting your tax return.

• Research and choose the right filing method for your situation: tax software, IRS Free File, paper forms or a tax professional.

• Report all your income and claim deductions and credits accurately to avoid errors, delays or amended returns.

• Review your return carefully and e-file when possible to speed up processing.

• Pay any taxes owed by the due date or request a payment plan. You can use the IRS “Where’s My Refund?” tool to track your refund status.
