If you are new to America, filing your first U.S. income tax return can sound intimidating.
You may hear people talking about:
- W-2
- 1099
- 1040
- Tax deductions
- Tax credits
- Refunds
- IRS
- Federal taxes
- State taxes
But for many employees with a relatively simple financial situation, filing a tax return is much easier than the actual government forms make it look.
You normally do not have to sit down with a blank Form 1040 and calculate every line yourself.
Tax software can ask you questions, collect information from your tax documents, perform the calculations and electronically file your return.
Let’s look at how the system works.
What Is Form 1040?
Form 1040, U.S. Individual Income Tax Return, is the main federal income tax return used by individual taxpayers.
Think of Form 1040 as the final yearly summary of your federal taxes.
During the year:
You earn money
↓
Your employer may withhold taxes
↓
You receive tax documents
↓
You report your income
↓
Deductions and credits are calculated
↓
Your final tax is calculated
↓
Taxes already paid are subtracted
↓
You may:
Receive a refund
or
Owe additional tax
Federal Taxes and State Taxes Are Different
Your Form 1040 is a federal tax return.
Depending on where you live, you may also have to file a separate state tax return.
For example, someone living in California may file:
Federal
Form 1040
and
California
Form 540
Tax software can often prepare both returns.
Step 1: Collect Your Tax Documents
Before filing, gather the documents that apply to you.
You may receive:
- W-2
- 1099-NEC
- 1099-K
- 1099-INT
- 1099-DIV
- 1099-B
- 1099-R
- SSA-1099
- Form 1098
- Form 1098-T
- Health insurance tax documents
- Childcare records
- Business records
- Investment records
You will not necessarily receive all of these.
If You Have a W-2
Employees generally receive a Form W-2.
One of the most important boxes is:
W-2 Box 1
This generally contains your federal taxable wages.
For the current Form 1040 structure, W-2 Box 1 generally flows to:
Form 1040 Line 1a
If your W-2 says:
Box 1: $50,000
then $50,000 would generally be included in wages reported on Line 1a.
Have more than one W-2?
Tax software generally adds them together.
Not sure what the other boxes mean?

What Happens to Federal Tax Already Taken From Your Paycheck?
Look at:
W-2 Box 2
This generally shows the amount of federal income tax your employer withheld.
Under the current Form 1040 structure, W-2 federal withholding generally flows to:
Form 1040 Line 25a
This amount is important because it represents tax you have already paid.
Why Do Some People Get a Tax Refund?
A refund is generally not free money from the government.
For a basic example:
Your final federal income tax:
$4,000
Federal income tax already withheld:
$5,000
Difference:
$1,000
You might receive approximately a $1,000 refund before considering other taxes, payments and credits.
Tax credits can also create or increase refunds in some circumstances.
Why Do Some People Owe Money?
Reverse the example.
Final tax:
$5,000
Tax already paid:
$4,000
Remaining:
$1,000
You may owe approximately $1,000.
This is why your paycheck withholding matters.
What Is a Tax Deduction?
A tax deduction generally reduces the income used in calculating your taxes.
It is not the same as receiving the deduction amount back in cash.
Suppose you qualify for a $1,000 deduction.
That usually does not mean:
IRS gives you $1,000.
Instead, the deduction may reduce income used in the tax calculation.
What Is a Tax Credit?
A tax credit works differently.
A credit generally reduces tax itself.
Some credits can also be refundable, meaning qualifying taxpayers may receive some or all of the credit even when the credit exceeds the tax otherwise owed.
Common tax credits can include, depending on eligibility:
- Child Tax Credit
- Earned Income Tax Credit
- Child and Dependent Care Credit
- Education-related credits
Eligibility rules can change, so do not assume that having a child or paying an expense automatically qualifies you.
Standard Deduction vs. Itemized Deductions
Most taxpayers generally choose between:
Standard deduction
A predetermined deduction based largely on filing status and other circumstances.
or
Itemized deductions
Specific qualifying expenses reported on Schedule A.
Tax software normally compares the available options and applies the appropriate result based on the information you enter.
Filing Status Matters
Your filing status affects many parts of your tax return.
Possible filing statuses include:
- Single
- Married filing jointly
- Married filing separately
- Head of household
- Qualifying surviving spouse
You cannot simply choose whichever one gives you the biggest refund.
Each filing status has eligibility rules.
Dependents Matter Too
Children and other qualifying dependents can affect:
- Filing requirements
- Tax credits
- Head-of-household eligibility
- Childcare credits
- Earned Income Tax Credit
- Education benefits
Tax software normally asks questions to determine whether someone qualifies as your dependent.
Can I File Form 1040 Online?
Yes.
In fact, electronic filing is how many Americans file their tax returns.
You have several options.
Option 1: IRS Free File
Before paying anyone, check IRS Free File.
For the 2026 filing season for 2025 tax returns, taxpayers with adjusted gross income of $89,000 or less can qualify for IRS Free File guided tax software.
The income threshold can change in future years, so always check the current IRS limit.
IRS Free File provides access to participating tax-software companies.
For the 2026 filing season, participating providers include companies such as:
- TaxAct
- FreeTaxUSA/TaxHawk
- TaxSlayer
- 1040.com
- Other participating providers
Eligibility rules can differ among providers.
Some offers may include free state filing while others may not.
Important
If you want to use an IRS Free File offer, begin through the official IRS Free File program rather than simply searching for a company’s website.
Option 2: Commercial Tax Software
You can also use commercial tax-preparation software.
Common examples include:
- TurboTax
- H&R Block
- TaxAct
- FreeTaxUSA
- TaxSlayer
BurmaHeaven is not recommending one particular company.
Prices, free tiers, features and eligibility can change.
Some products may advertise free filing but charge depending on:
- Tax forms required
- State returns
- Self-employment
- Investments
- Additional services
Check the actual cost before completing your return.
Option 3: Free File Fillable Forms
The IRS also offers Free File Fillable Forms.
Unlike guided tax software, these are closer to electronic versions of IRS tax forms.
They are generally better suited to someone who already understands how to prepare a tax return.
They provide less step-by-step help than guided software.
Option 4: Free Tax Preparation Through VITA or TCE
Some people can receive free tax preparation from IRS-sponsored volunteer programs.
VITA
Volunteer Income Tax Assistance
TCE
Tax Counseling for the Elderly
VITA programs often serve taxpayers who qualify under program guidelines and can also provide language support at some locations.
This can be especially useful if you are new to the U.S. tax system and are uncomfortable filing your first return alone.
Option 5: Hire a Tax Professional
You can also hire:
- CPA
- Enrolled agent
- Tax attorney
- Qualified professional tax preparer
Professional help can be particularly useful when you have situations such as:
- Business ownership
- Complicated investments
- Rental property
- Foreign income or assets
- Multiple states
- Large capital gains
- Complex immigration/tax residency questions
- Complicated deductions
- Prior-year tax problems
Remember that you remain responsible for the accuracy of the tax return you sign.
Filing Taxes as a New Immigrant
U.S. immigration status and U.S. tax residency are related issues, but they are not exactly the same legal test.
Tax filing obligations can depend on factors such as:
- Citizenship
- Green card status
- Days physically present in the United States
- Type of income
- Tax residency rules
- Treaties
- Filing status
People with complicated immigration or international tax circumstances may need professional advice.
SSN or ITIN
Federal tax returns generally require an appropriate Taxpayer Identification Number.
For many people, this is a:
Social Security Number — SSN
Some people who are not eligible for an SSN may instead qualify to apply for an:
Individual Taxpayer Identification Number — ITIN
An ITIN is a tax-processing number.
Receiving an ITIN does not itself provide immigration status or employment authorization.
What If I Am Self-Employed?
This changes things considerably.
If you earn money operating your own business, freelancing or providing independent services, you may have to report business income and expenses.
For many sole proprietors, this involves:
Schedule C
Profit or Loss From Business
You may also have to calculate:
Self-employment tax
using Schedule SE.

→ Self-Employment Taxes, Business Expenses, Inventory & Accounting
What If I Receive a 1099?
A 1099 is not the same thing as a W-2.
A 1099 can report several different types of income.
For example:
- 1099-NEC
- 1099-K
- 1099-INT
- 1099-DIV
- 1099-B
- 1099-R
Do not assume that every 1099 means you are self-employed.
The type of 1099 matters.
What If I Earned Money but Never Received a Tax Form?
Do not assume that income becomes tax-free because you never received a W-2 or 1099.
Tax reporting obligations are generally based on the underlying income and tax rules — not simply whether somebody mailed you a form.
This is especially important for self-employed people.
When Are Taxes Due?
The normal federal filing deadline is generally around April 15, although weekends, holidays, disasters and other special circumstances can change deadlines.
Always check the IRS for the current filing deadline.
What Does a Tax Extension Do?
A filing extension generally gives you more time to file your return.
It does not automatically give you additional time to pay tax you owe.
This distinction is extremely important.
After You File
Keep copies of:
- Your filed return
- W-2s
- 1099s
- Supporting tax documents
- Business records
- Receipts where applicable
You can also create an IRS Online Account to access certain tax records and account information.
The Simple Version
For someone with a normal W-2 job, filing taxes may look something like this:
Receive W-2
↓
Choose tax software
↓
Enter your personal information
↓
Enter W-2
↓
Answer questions about your family and income
↓
Software calculates deductions and credits
↓
Review federal return
↓
Prepare state return if required
↓
E-file
↓
Receive refund or pay balance
Before You Pay for Tax Software
Check these options first:
- IRS Free File
- VITA/TCE free tax preparation
- Any free filing option for which you legitimately qualify
Then compare commercial options such as TurboTax, TaxAct, H&R Block, FreeTaxUSA and TaxSlayer if you need additional features.
