Preparing for tax season is mostly about gathering the right things before you sit down to file. When the documents are ready and you know what changed during the year, filing is a short task. When they are not, it becomes a scramble.
This guide walks Allen, TX filers through the full process. It explains when to start, what to collect, which life changes matter, which deductions and credits to check, and how to choose a filing method. It also covers the basics if this is your first return.
Filing from Texas has a few local wrinkles worth knowing, and we cover those too. If you would rather hand it off, see our tax preparation services.
When to start
Start earlier than you think. Most of the work is collecting documents, and that happens on other people’s schedules, not yours.
The federal calendar is predictable. The IRS opens the filing season in late January and sets a deadline in mid-April. In the most recent season, the IRS opened on January 26, 2026 with an April 15, 2026 deadline for tax year 2025 returns (IRS). When the deadline falls on a weekend or holiday, it shifts, so confirm the date for the season you are filing in.
A simple rhythm works well. In December, take stock of what changed during the year and make any moves that must happen before December 31. In January, collect documents as they arrive. In February, review and file once everything is in.
There is one thing worth resisting. Do not file the moment you have your first form. Filing before all your documents arrive is a common source of errors, because a form you forgot can turn into an amended return later.
If you expect to owe, starting early has a second benefit. Knowing the number in February gives you until the deadline to arrange the payment, rather than discovering it the week it is due.
Documents to gather
Build a single folder, digital or paper, and add to it as things arrive. Here is what most Allen filers need.
Identification and basics
- Social Security numbers for you, your spouse, and every dependent, matching the cards exactly.
- Last year’s tax return. It works as a checklist, and some items carry forward from one year to the next.
- Bank routing and account numbers for direct deposit.
Income documents
- Form W-2 from each employer.
- Form 1099-NEC for freelance or contract income. Form 1099-MISC for other reportable payments, such as rents, when applicable.
- Form 1099-K for business payments received through cards, payment apps, or online marketplaces.
- Forms 1099-INT and 1099-DIV for interest and dividends.
- Form 1099-R for retirement distributions and Form 1099-B for brokerage transactions.
- Records of any income that never generates a form, which is still reportable.
Deduction and credit documents
- Mortgage interest on Form 1098, and your property tax statement.
- Charitable donation receipts and acknowledgment letters.
- Medical expense records, if they may be large enough to matter.
- Student loan interest on Form 1098-E and tuition on Form 1098-T.
- Childcare provider details, including their tax identification number.
- IRA and HSA contribution records. An HSA is a health savings account, not a retirement account.
If you run a business or have self-employment income, you also need your income and expense records for the year. The IRS expects records that clearly show your income and expenses. Our tax document checklist covers the full list in more detail.
A practical tip. Keep a running list of every income source from last year, then check each one off as the form arrives. When the list is complete, you are ready to file.
Life changes that affect taxes
Most surprises at tax time trace back to something that changed during the year. None of these announce themselves on a form, so they are worth reviewing deliberately.
- Marriage or divorce, which changes your filing status and possibly your name in Social Security records.
- A new baby, an adoption, or a dependent who moved in or out.
- A dependent who turned 17, since some credits change with age.
- Buying or selling a home, which affects mortgage interest, property taxes, and possibly gain on the sale.
- A move, especially between states. You may need to file a part-year return, meaning a return covering only the months you lived in that state.
- A job change, including a period of unemployment, since unemployment compensation is generally taxable.
- Starting a side business or freelance work, which brings self-employment tax and possibly estimated payments.
- Retirement, or beginning to take distributions from a retirement account.
- A large medical event, or paying tuition for yourself or a dependent.
If any of these happened, mention them when you file or when you meet your preparer. A change you consider personal news is often a tax event too.
Moving deserves a note for Texas newcomers. If you moved to Allen from a state with an income tax, you may still need to file a part-year return in the state you left, even though Texas does not have one.
What is different for Allen and Collin County filers
Filing from Texas is simpler in one way and more involved in another.
The simple part: Texas does not levy a personal state income tax. Most Allen residents file a federal return only, with no separate state individual income tax return to prepare. That removes a whole step that filers in most other states deal with.
The involved part is property tax. Texas funds a great deal locally, so property taxes carry more weight here. For homeowners, that matters at tax time in two separate ways, and it is worth keeping them straight.
Property tax and your federal return
Property taxes you paid may be deductible on your federal return. Two conditions apply. You have to itemize, and the deduction is capped.
That cap covers state and local taxes together, which is often shortened to SALT. The limit was raised for recent filing years and is reduced for taxpayers above certain income levels. The figure changes by year, so confirm the limit for the year you are filing rather than assuming a number.
Property taxes may form a significant part of that deduction for some Texas homeowners, because there is no state income tax here to count toward the same cap.
The homestead exemption, which is separate
Your homestead exemption is a property tax matter, not a federal filing matter, and it is handled by the appraisal district rather than the IRS. It still belongs on your spring calendar. For a general residence homestead exemption, you file the application with the Collin Central Appraisal District between January 1 and April 30. Early applications are not accepted.
If you missed the April 30 deadline, late filing may still be available. Check the current Collin CAD rules before assuming you have lost the exemption.
The timing lines up conveniently. The federal deadline sits in mid-April and the homestead application window closes at the end of April, so if you handle them in the same stretch of spring, neither gets forgotten. They are separate filings with separate offices, but one calendar reminder can cover both.
If you bought a home in Allen during the year, check your property record rather than assuming the exemption carried over from the previous owner. It does not transfer automatically.
You can check your exemption status and property record through the Collin Central Appraisal District. It is worth a look each spring, because an exemption that was removed after an ownership or address change will not fix itself.
Deductions and credits to check
The goal is not to claim everything. It is to claim what you actually qualify for, and to have the records that support it.
Start with the basic choice. You either take the standard deduction or itemize, whichever produces the better result. Since the standard deduction rose, fewer filers itemize, but homeowners with a mortgage and sizeable property tax bills should still run the comparison rather than defaulting.
Items worth checking include student loan interest, educator expenses, qualifying retirement contributions, and childcare costs. Charitable donations are a separate issue. They need written records behind them, so keep receipts and acknowledgment letters.
Credits are worth more attention than deductions, because a credit reduces tax directly. Check whether you qualify for child-related credits, education credits, or the Earned Income Tax Credit. Eligibility rules are specific, so check the actual requirements rather than relying on what you heard.
2026 TAX FILING UPDATE
For the 2026 filing season, the IRS introduced Schedule 1-A for recently enacted deductions, including deductions related to tips, overtime, car loan interest, and an enhanced deduction for seniors (IRS). Because these provisions are new, confirm the eligibility rules before claiming them.
Filing for the first time? Start here
If this is your first return, the vocabulary is the hardest part. Here is the short version.
Gross income generally includes your taxable income before deductions. Some types of income may be excluded under tax rules. Deductions reduce the income you are taxed on. Credits reduce the tax itself, which makes them more valuable dollar for dollar. Withholding is the tax already taken from your paychecks during the year.
A refund is not a bonus. A refund may come from excess withholding, refundable credits, or both. A balance due can result from low withholding, self-employment income, investment income, or insufficient estimated payments. Owing at filing is not automatically a mistake.
Do you have to file? It depends on your income, your filing status, your age, and the type of income you received. Some people below the filing threshold still benefit from filing, because refundable credits or withheld tax can produce a refund they would otherwise miss.
Two habits make every future year easier. Keep a folder for tax documents starting in January, and check your withholding after any pay or life change, so next April holds fewer surprises.
Filing options
There are three broad paths, and the right one depends on how complex your return is and how much you want to handle yourself.
| Option | Works well when | Watch out for |
|---|---|---|
| File it yourself | A straightforward return, such as W-2 income and the standard deduction | You are responsible for catching your own errors |
| Tax software | Moderate complexity, and you are comfortable answering prompts | Software checks calculations, not whether your answers were right |
| A tax professional | Self-employment, rentals, a home sale, multiple states, or big life changes | Costs more, and you still review the return before it is filed |
Some free filing programs have income or eligibility limits. Other options, including IRS Free File Fillable Forms, may be available regardless of income for people comfortable preparing their own returns. It is worth checking what you qualify for before paying for software.
Whichever route you choose, review the return before it is filed. Check that the names and Social Security numbers are right, that the income matches your documents, and that the bank details are correct. Using a preparer does not remove your responsibility for the return.
