After a long winter, it’s finally April. Time for warmer temperatures, blooming flowers — and taxes. April isn’t just the beginning of spring; it’s also the peak of tax season. And if you haven’t already filed your taxes, now is definitely the time.

Diving in right now may seem daunting, but it doesn’t have to be — not if you have a complete tax filing checklist.

Looking for a quick guide, I turned to ChatGPT and asked the AI to create a checklist specifically for last-minute tax filers. Here’s what it came up with, and why it’s worth keeping handy.

Do you have every form or document that reports the income you earned during the year? Here are some major documents and information to have on hand:

  • W-2s (from employers)

  • 1099 forms (freelance, contract, interest, dividends and other nonemployee income)

  • Investment income statements

  • Retirement distributions (if applicable)

“Missing even one document could delay your filing or trigger IRS notices later,” the AI warned.

Before entering any numbers, ChatGPT encourages you to pause and proofread. Here’s what you need to double-check:

  • Verify your Social Security number (and your dependents’)

  • Confirm the spelling of names

  • Update your current address

  • Check your filing status (single, married, head of household, etc.)



This task may seem like a nuisance, but ChatGPT offered a clear warning: “Small errors here can cause big delays in processing.”

ChatGPT doesn’t want you to “leave money on the table” by missing out on potential credits and deductions. It recommends gathering records for common deductions and credits, including:

  • Student loan interest payments

  • Mortgage interest (Form 1098)

  • Qualified medical expenses

  • Charitable donations

  • Child care expenses

  • Education credits

As always, review this information carefully. The AI reminds you that “if you’re itemizing, accuracy is key.”

You may be tempted to think of last year’s tax return as old news, but ChatGPT says it’s a valuable reference when filing again.

Your prior return can help you find:

  • Carryforward deductions or credits

  • Adjusted gross income (AGI), which may be used for identity verification

  • Forms or income types that tend to repeat year to year

Don’t know where your old tax return is? Here’s some good news: You can access past returns by creating an online account with the IRS or through the tax software or preparer you used previously.

How you file is a personal decision, guided by how complex your situation is and how much help you want.

ChatGPT breaks down your main options:

  • DIY tax software (fast and guided)

  • Professional tax preparer (helpful for more complex returns)

  • Free filing options (if eligible)



The AI does have one suggestion: “Last-minute filers often benefit from software that flags errors in real time,” it said.

Confused by these options? ChatGPT explains it simply:

  • The standard deduction is faster and simpler

  • Itemizing may save more if you have significant deductible expenses

Ultimately, the choice is yours, but the AI offers this advice: “Choose the option that gives you the biggest tax benefit,” it said.

If you’re expecting a refund, ChatGPT recommends entering your bank routing and account numbers carefully — and checking them twice.

If you owe taxes, paying electronically can speed things up. And if you can’t pay the full amount right away, the IRS offers installment plans that allow you to pay over time.

You may be coming down to the wire on your taxes, but ChatGPT emphasizes one thing above all else: Take your time and do it right.

“Even if you’re filing at the last minute, accuracy matters more than speed,” it said. “Take a few extra minutes to review everything carefully — it could save you from headaches down the road.”
