January is when most people start thinking about taxes again. Filing season opens, W-2s begin to arrive, and there’s a general feeling that you should either file immediately or avoid it altogether. Both approaches usually lead to problems.
Why January Tax Preparation Matters More Than People Think
The truth is simple: January isn’t about filing your tax return. It’s about preparing for it. That is why January Tax Preparation is important!
Every year, many taxpayers rush to file as soon as the IRS opens the system, only to realize later that they missed a form, forgot income, or claimed something incorrectly. These small oversights can result in delayed refunds, amended returns, or unnecessary IRS letters, all of which could have been avoided with a bit of planning.
January is the one month where you have the most control and the least pressure. You’re early enough to gather documents, review what changed since last year, and make informed decisions before filing season becomes stressful. This matters even more if you have multiple income sources, freelance or gig work, dependents, or major life changes during the year.
This guide is written for everyday U.S. taxpayers, not tax professionals. Whether you’re a W-2 employee, a freelancer, a small business owner, or a parent navigating credits and deductions, the steps below will help you start tax season calmly, clearly, and confidently, without rushing or guessing.

Understand the 2025 Tax Filing Timeline
One of the biggest sources of tax stress is not knowing when things actually happen. Many people assume that once January starts, they should already be filing. In reality, the first few weeks of the year are meant for waiting, organizing, and reviewing, not rushing.
When the IRS Typically Opens Filing Season
The IRS usually begins accepting federal tax returns in mid to late January. While the exact date can change slightly each year, the opening of filing season does not mean you’re required to file immediately. It simply means the system is open for those who are truly ready.
Filing early only makes sense if:
- You have all your income documents
- Nothing significant changed from last year
- You’ve reviewed your information carefully
For most taxpayers, that’s not the case in early January. But it still counts if you jump in on time, with your January tax preparation steps.
Why Most Tax Documents Arrive Later in January
As a part of their January tax preparation procedures, employers and financial institutions are generally required to send tax forms by January 31. That means many important documents don’t arrive until the last week of January or even early February.
Common examples include:
- W-2s from employers
- 1099 forms for freelance, contract, or gig work
- Bank and investment income statements
Filing before receiving all required forms increases the risk of missing income, which can lead to delays or IRS notices later.
Key January and Early-Year Tax Dates to Know
Understanding a few basic deadlines can help you plan without pressure:
- January 31: Deadline for employers and payers to send W-2s and most 1099s
- Late January: IRS begins accepting returns
- April 15 (typically): Federal tax filing deadline
- Quarterly estimated tax deadlines may apply if you’re self-employed
These dates are guideposts, not reasons to panic.
Early Organization vs. Early Filing
There’s a big difference between getting ready early and filing early. January is the ideal time to:
- Create a tax folder
- Track which documents have arrived
- Review last year’s return
- Note any life or income changes
By focusing on preparation instead of speed, you set yourself up for a smoother, more accurate tax filing when the time is right.
January tax preparation isn’t optional for anyone involved in taxes.
The government updates systems, employers issue W-2s, banks and platforms prepare tax forms, and individuals begin organizing income and records. Whether you realize it or not, everyone in the tax loop starts the process in January. The only difference is whether you’re prepared or playing catch-up later.
Gather the Tax Documents You Can Expect in January
One of the most productive things you can do in January is start collecting your tax documents. You don’t need everything right away, but you do need to know what to expect and how to organize it. Missing or incorrect forms are one of the most common reasons tax returns get delayed or flagged.
Income Documents
Most January tax paperwork relates to income you earned during 2025. Even if you already track your earnings, you still need the official forms that get reported to the IRS.
Common income documents include:
- W-2 forms from employers, showing wages and withheld taxes
- 1099-NEC for freelance or independent contractor income
- 1099-MISC for other types of income, such as prizes or certain payments
- 1099-K for payments received through platforms or payment apps
- 1099-INT and 1099-DIV from banks and investment accounts
- Unemployment income statements, if applicable
Even if the income feels small, it still matters. If a payer reports it to the IRS, it needs to appear on your return.
Common Missing or Delayed Forms
It’s normal for some documents to arrive later than others. Investment accounts, brokerages, and certain payment platforms often issue corrected forms or send them closer to the end of January or early February.
If a form hasn’t arrived yet:
- Don’t guess the numbers
- Don’t use estimates from bank deposits
- Don’t file until you’ve confirmed all expected forms are in
Filing with incomplete information can trigger IRS matching issues, which slow down refunds and may require corrections later.
How to Organize Documents Now
January is the perfect time to create a simple system. It doesn’t need to be fancy. It just needs to be consistent.
Helpful organization tips:
- Create one digital folder labeled by tax year
- Save documents with clear names, such as “2025 W-2 – Employer Name”
- Keep paper copies in one physical location if you prefer
- Track which forms you’re still waiting on
Good organization early in the year makes the rest of tax season faster, calmer, and far less error-prone.
Review Last Year’s Tax Return Before You Do Anything Else
Before you start entering numbers or uploading documents, take a few minutes to look at your 2024 tax return. This is one of the most overlooked steps in tax preparation, yet it’s one of the most useful. Your prior return acts as a roadmap for what to expect this year.
Why Last Year’s Return Is Your Best Reference
Your tax situation rarely changes completely from one year to the next. Reviewing last year’s return helps you:
- Remember income sources you might otherwise forget
- Spot deductions or credits you previously qualified for
- Identify items that may carry over into the new year
It also reduces the chances of accidentally leaving something out, which is a common cause of IRS notices.
Key Sections to Review Carefully
As you look through your prior return, pay special attention to:
- Income sources: Employers, freelance clients, side work, or investment income
- Credits and deductions: Child-related credits, education credits, or business deductions
- Carryovers: Capital losses, charitable contributions, or credits that rolled forward
- Withholding and payments: Whether you owed or received a refund
If something appeared last year, there’s a good chance it may apply again, even if the amount changed.
Red Flags That May Require Extra Attention
Certain signs suggest this year’s return may be more complex:
- You owed a large balance or received an unexpectedly small refund
- You had multiple income streams
- You claimed deductions that required detailed records
- You received IRS letters or corrections
Catching these issues early gives you time to ask questions or seek help if needed.
How This Step Saves Time Later
Spending 15 minutes reviewing last year’s return in January can save hours later. It helps you file more accurately, reduces last-minute scrambling, and gives you a clearer picture of what this tax season will actually look like.
Check for Life Changes That Affect Your Taxes
Even if your income looks similar to last year, life changes can significantly affect your tax return. The IRS bases many rules, credits, and calculations on personal circumstances, not just numbers. January is the best time to step back and take inventory of what changed during the year.
Income Changes
Income changes don’t always mean earning more. Any shift matters.
Examples include:
- Starting a new job or changing employers
- Receiving a raise, bonus, or commission
- Losing a job or working fewer hours
- Beginning freelance, contract, or gig work
- Having multiple income sources for the first time
These changes can affect withholding, estimated taxes, and whether you owe or receive a refund.
Family Changes
Family-related changes often impact filing status and credits, which directly affect how much tax you pay.
Common examples:
- Marriage or divorce
- Having a child or adopting
- Changes in custody or dependents
- Paying for childcare or dependent care
- A dependent aging out or becoming financially independent
Even small details, such as who paid more than half of a dependent’s support, can change eligibility for certain credits.
Housing and Major Financial Moves
Large financial decisions often have tax consequences people don’t realize until filing time.
Consider whether you:
- Bought or sold a home
- Refinanced a mortgage
- Moved to a different state
- Paid significant medical expenses
- Made large charitable contributions
These events may create deductions, credits, or reporting requirements.
Why the IRS Cares About These Changes
The IRS compares your current return to prior years and to information reported by third parties. When life changes aren’t reflected correctly, it can trigger:
- Filing status errors
- Incorrect credit claims
- Delayed refunds
- Requests for documentation
By identifying changes early, you reduce the risk of mistakes and make the rest of tax season far smoother.
Taking time in January to acknowledge what changed gives you clarity before complexity, which is exactly what tax preparation should be.
Common January Tax Mistakes to Avoid
January is when many tax problems quietly begin. Most aren’t caused by complicated rules, but by rushing, guessing, or assuming nothing changed. Avoiding a few common mistakes early can save you weeks of frustration later.
Filing Before All Documents Arrive
One of the most frequent January mistakes is filing as soon as the IRS opens, without waiting for all income forms. Missing even one 1099 can cause your return to be flagged for income mismatch.
If a payer reports income to the IRS and it’s not on your return, the IRS will notice. This often leads to:
- Delayed refunds
- IRS notices
- Amended returns
Waiting a little longer is usually safer than filing fast.
Forgetting Side Income or Gig Work
Side income is easy to overlook, especially if it came from multiple platforms or was irregular. Payment apps, online marketplaces, and freelance platforms report income separately, and the IRS expects consistency.
Even small amounts matter if they were reported. Forgetting them is one of the quickest ways to create problems.
Claiming Dependents Incorrectly
January is also when people assume their dependent situation stayed the same. Changes in custody, income, or living arrangements can affect:
- Who can claim a child
- Eligibility for child-related credits
- Head of household filing status
Claiming a dependent incorrectly often results in rejected returns or follow-up letters.
Using Outdated Personal Information
Simple details still matter. Using an old address, incorrect Social Security number, or outdated bank information can:
- Delay refunds
- Cause identity verification issues
- Result in rejected electronic filings
January is a good time to verify that everything is current.
Assuming This Year Will Match Last Year
Perhaps the biggest mistake is assuming nothing changed. Even small differences in income, family status, or benefits can affect the final result.
Taking time in January to slow down and double-check details helps you avoid preventable errors that cost time, money, and peace of mind. As you employ the best January tax preparation practices, you get plenty of time to check on everything tax related.
Decide How You’re Going to File This Year
Before you start entering numbers, it helps to decide how you’re going to file your tax return. Many people wait until the last minute to make this choice, which often leads to rushed decisions. January is the right time to step back and choose the approach that actually fits your situation.
Filing Yourself vs. Using a Tax Professional
For some taxpayers, filing on their own makes sense. If your situation is straightforward, with a single W-2 and no major changes, tax software can be efficient and cost-effective.
However, using a tax professional may be worth considering if you:
- Have freelance, contract, or business income
- Earn income from multiple sources
- Own a small business or rental property
- Experienced major life changes
- Owed taxes or received IRS notices in the past
The goal isn’t to spend more money. It’s to reduce mistakes and stress.
Questions to Ask Before Choosing
Ask yourself a few honest questions:
- Was last year’s return simple or confusing?
- Did I feel unsure about what I was entering?
- Did I receive a much smaller refund or owe more than expected?
- Am I guessing about deductions or credits?
If the answer to several of these is yes, extra support may be helpful.
What to Prepare If You Plan to Work With a Tax Pro
If you decide to use a professional, January is the best time to start preparing. Waiting until March often means limited availability and rushed appointments.
Helpful steps include:
- Gathering income documents as they arrive
- Listing questions or concerns from last year
- Noting any life or income changes
- Scheduling early consultations if possible
Planning this early gives you more flexibility and a smoother filing experience when the time comes.
Popular Tax Preparation Services Worth Considering
If you decide to file your taxes using online software or professional services, January is a good time to compare options. Different platforms work better for different situations, and choosing early helps avoid rushed decisions later in the season.
Below are a few well-known tax preparation services that TaxBraix has reviewed and that many U.S. taxpayers consider during filing season:
- TaxSlayer
Often chosen by budget-conscious filers, TaxSlayer is known for straightforward pricing and solid support for common tax situations, including freelance and small business income. - E-file.com
A simpler option aimed at basic to moderately complex returns. It can be a good fit for taxpayers who want a guided experience without extra features they don’t need. - ezTaxReturn.com
Designed for speed and ease of use, ezTaxReturn.com appeals to filers with relatively straightforward tax returns who want to file quickly and efficiently. - Liberty Tax

The right choice depends on how complex your tax situation is, your comfort level with filing on your own, and whether you want personal support. Reviewing your options in January gives you time to choose carefully instead of defaulting to the first service you see when filing season gets busy.
Plan Ahead for Your Refund or Balance Due
One of the biggest questions people have every tax season is simple: Will I get a refund, or will I owe? While you may not know the exact number in January, early planning helps prevent unpleasant surprises. Yes, January tax preparation plays a big role here.
Why Your Refund May Look Different This Year
Many taxpayers expect a refund similar to last year, but refunds change often. Differences in income, withholding, credits, and deductions can all shift the final result.
Common reasons refunds decrease or balances increase include:
- Earning more income without adjusting withholding
- Starting freelance or gig work without making estimated payments
- Changes in child-related or education credits
- Fewer deductions due to life changes
Understanding this early helps you plan instead of react.
What to Do If You Expect a Refund
If you typically receive a refund:
- Double-check your bank information for direct deposit
- Avoid filing too early with incomplete documents
- Consider how you plan to use the refund, especially if it’s smaller than expected
A refund isn’t a bonus. It’s money you overpaid, and accuracy matters more than speed.
What to Do If You Expect to Owe
If there’s a chance you’ll owe:
- Start setting aside funds in January
- Review estimated tax requirements if you’re self-employed
- Avoid ignoring the issue and hoping it “works out”
Planning early gives you time to prepare, explore payment options if needed, and reduce stress.
Why January Tax Preparation Makes a Difference
Facing your refund or balance situation early puts you in control. Instead of scrambling in April, you can make informed decisions calmly, which is exactly how tax season should feel.
