How to Prepare for Tax Season: A Simple Checklist

Every January, the holiday decorations come down and the calls start coming in, almost always with the same question: “What paperwork do I actually need this year?”

It’s a fair question. Tax season sneaks up on people, and between W-2s, 1099s, receipts stuffed in a kitchen drawer, and a tax law change or two, it’s easy to feel behind before you’ve even started.

Here’s the good news: knowing how to prepare for tax season isn’t complicated once you break it into steps. It’s mostly about gathering the right paperwork early, understanding what changed since last year, and not waiting until the second week of April to hunt for your mortgage interest statement. We put this checklist together based on what trips up Buffalo homeowners and small business owners year after year.

Start Gathering Your Income Documents Early

The first step is simple: collect every document that reports income. That means W-2s from employers, 1099-NEC or 1099-MISC forms if you freelance or did contract work, 1099-INT or 1099-DIV forms from banks and investment accounts, and any 1099-R if you took a distribution from a retirement account.

Many common income forms are issued by the end of January — often landing in your mailbox while you’re still shoveling out from the first real lake-effect storm — although some documents and corrected forms can arrive later. They don’t all show up at once, and a few stragglers, especially brokerage statements, tend to come in mid-February.

We tell clients to create one folder, digital or physical, and drop every tax document into it the moment it arrives. Don’t sort it. Don’t organize it yet. Just collect it. Sorting comes later, and it’s a lot less painful when everything is already in one place.

Pull Together Deduction and Credit Records

This is where a lot of people leave money on the table.

If you own a home in the Buffalo area, keep your mortgage interest statement and property tax records. With the older housing stock around here, projects like a new furnace, insulation, or windows come up a lot — but note that the federal energy-efficiency credits for those improvements ended for property placed in service after December 31, 2025, so most newer projects won’t qualify at the federal level. New York State and utility programs may still offer incentives worth checking, and if you completed a project before that cutoff, hold onto the documentation.

If you have kids, gather records related to childcare costs and education expenses. If you run a small business or side hustle, mileage logs, receipts for supplies, and home office expense records all matter — our year-end tax planning checklist for small businesses covers what to lock down before December 31 so this part of tax season is already done.

The habit that saves people the most stress here is tracking these throughout the year, rather than reconstructing them in March from memory and bank statements.

Review What Changed From Last Year

Life doesn’t stay the same, and neither does your tax situation.

Did you buy a house? Get married or divorced? Have a baby? Start a new job or lose one? Move to a new address? Pick up freelance work on the side? Every one of these changes something on your return, sometimes in ways that surprise people.

A new home purchase, for instance, may introduce mortgage interest and property tax considerations that weren’t relevant before, depending on how you file and which deductions you qualify for. A new baby means a dependent and possibly the Child Tax Credit.

A career change might mean juggling W-2 and 1099 income in the same year, which can affect your taxable income and, depending on the type of work, your self-employment tax. Running through this list before you file catches most of the surprises before they catch you.

Know Whether You’re Filing Yourself or Getting Help

Not every return needs a professional. If your situation is straightforward — one job, the standard deduction, no side income — filing software can often handle it well and affordably. Eligible taxpayers may also qualify for free tax preparation assistance through IRS-sponsored VITA or TCE programs.

Where it gets more complicated is self-employment income, rental property, multiple income streams, or a life event like a home sale. That’s usually when a professional set of eyes is worth it — not because you can’t figure it out, but because the tax code has a lot of small rules that change the outcome. And if your books are behind, catching up before you file makes everything easier — our bookkeeping services keep Buffalo businesses tax-ready year-round.

At KD Accounting & Tax, we see returns every year where a client missed a credit they qualified for simply because they didn’t know it existed. That’s the kind of thing a second look catches.

Understand Key Deadlines and Avoid Penalties

The federal filing deadline is generally in April, and New York State’s individual income tax deadline generally follows the federal deadline. Interest and applicable late-payment penalties can continue to accrue on unpaid tax after the original payment deadline.

If you expect to owe money, it’s smart to make a payment by the original deadline even if you’re filing the actual return later, since interest and penalties start accruing regardless of the extension.

Missing deadlines without a plan is one of the most avoidable mistakes we see. A five-minute extension filing can save you a real headache compared to filing late with no explanation.

Set Up for a Faster, Safer Refund

If you’re expecting a refund, direct deposit is faster and more secure than waiting for a paper check.

Checks can get lost, stolen, or delayed — especially with the winter mail slowdowns that are a fact of life around here. Direct deposit also lets you split your refund across multiple accounts, which is a useful trick if you want part of it going straight into savings before you’re tempted to spend it.

Once you file, you can use the IRS online refund tracker to check your status and see when more information becomes available.

Watch for Tax Season Scams

Every year without fail, tax season brings a wave of scams targeting people who are simply trying to do the right thing. The IRS generally starts contact by mail, while scammers lean on urgent phone calls, emails, or texts to pressure people into making immediate payments.

Be especially cautious of anyone threatening arrest, demanding unusual payment methods like gift cards or wire transfers, or refusing to give you time to verify the claim.

Be equally careful with tax preparers who promise unusually large refunds before they’ve even looked at your documents, or who want to base their fee on a percentage of your refund. Paid tax return preparers generally need a valid Preparer Tax Identification Number (PTIN), and you should be wary of anyone who pressures you to sign without reviewing the return.

Think Ahead About What to Do With Your Refund

A refund isn’t found money — it’s your own money coming back to you, so it’s worth a little planning.

Some homeowners put it toward an emergency fund, especially given the unpredictable repair costs that come with owning property in a climate like ours. A roof, a sump pump, or a furnace rarely fails on a convenient schedule. Others use it to pay down higher-interest debt or make an extra payment on their mortgage principal, which can meaningfully cut the interest paid over the life of the loan.

There’s no wrong answer here, but having a plan before the money lands in your account tends to lead to better decisions than spending it as it comes in.

Local Considerations for Buffalo and Western New York Filers

If you’re a homeowner in Buffalo or the surrounding suburbs, a few things are worth double-checking. Your property tax payment records matter if you itemize, so keep what you’ve paid on your city or county bills where you can find it.

New York State also has its own set of credits separate from the federal ones — including the household credit and, for lower-income households, the real property tax credit claimed on Form IT-214 — so it’s worth reviewing your federal and state returns together rather than treating them as separate tasks. And while it’s handled outside your income tax return entirely, this time of year is also a good reminder to make sure your STAR registration is current if you own your home.

Knowing how to prepare for tax season in a place with our particular mix of winters, older housing stock, and mixed income sources means paying attention to details a generic national checklist might skip.

Bringing It All Together

Preparing for tax season doesn’t have to feel like a scramble. Start early, keep your documents in one place as they arrive, review what changed in your life over the past year, and decide early whether you need professional help.

The people who stress the least in April are usually the ones who started organizing in January — not because they’re naturally more organized, but because they gave themselves the runway to catch mistakes before they became problems.

At KD Accounting & Tax, we walk clients through this exact process every year, and the ones who follow a simple checklist consistently end up with fewer surprises and less last-minute stress. Preparing for tax season really does come down to a handful of manageable steps, done a little early rather than all at once.
