NTA Final Tax Return 2026: The Complete Guide for Beginners and the Automatic Refund Trap
It's that time of year again—the season that gives both salarymen and freelancers a headache: final tax returns. With a decade in this game and countless filings under my belt, I've watched the National Tax Agency (NTA) website evolve. It's definitely become much more user-friendly. However, I'm also hearing a lot of chatter like, "I heard you can get a refund automatically now," or "Deduction amounts have gone up, right?" Based on the latest info as of February 2026, I'm here to give you an insider's perspective on how to breeze through your NTA tax return.
First, Let's Reconfirm the Filing Period and Who Needs to File
The filing period for the 2026 final tax return (for 2024 income) is Monday, February 16, 2026, through Monday, March 16, 2026. You've got that down, right? However, applications for refunds are accepted starting in January. So, if you had significant medical expenses or made furusato nozei (hometown tax donations), I highly recommend filing early via e-Tax. Honestly, I knock mine out in early February every year and treat the refund like a little bonus.
The Rumor Mill: Are Deductions Really Going Up? Here's the Real Deal.
I've been getting more questions like, "The basic deduction is going up to ¥480,000 this year, right?" It's true that a revision has been passed to increase the basic deduction to ¥480,000 for income tax starting from fiscal year 2025 (for 2025 income). But—and this is crucial—for the return you're filing now (for fiscal year 2024 = 2024 income), it's still ¥380,000. There's talk floating around on social media about a "¥155,000 increase," but that's for next year and beyond. To avoid making a mistake on your application, double-check that you're using the correct figures for the 2024 tax year.
The NTA Website Just Got Better! A Quick How-To Guide
Search for "final tax return guide," and the official NTA site is the first result. This year, the "chatbot" and "pre-fill feature" have gotten significant upgrades. If you're feeling lost on "how to use the NTA site for your tax return," start on the homepage and head to the "Final Tax Return Form Preparation Corner." Just answer the questions, and it will automatically guide you to the correct input form. It might feel a bit overwhelming at first, but once you start, just scanning your My Number Card automatically populates your address and birthdate. Compared to the days of filling everything out by hand, it's a massive timesaver.
Real User Reviews: What People Are Saying
Scrolling through online reviews for the NTA tax return process, you'll see comments like, "I was able to complete everything on my smartphone," and "Entering medical expenses is a pain." It's true that manually entering all those medical expense details takes time. But now, you can use the "Medical Insurance Statement Information" issued by pharmacies and hospitals and import it all at once through My Portal. Using this feature cuts down the input time dramatically. I used it this year and was done in 10 minutes.
Is the Refund Really Automatic? Watch Out for This Trap.
When you file for a refund, it's now standard to get your money back via an "automatic refund." Just register your bank account, and the money is deposited about one to two months after you file. But here's a word of caution: If there are errors in your filing, it won't just delay your refund; you could be asked to file an amended return later on. Mistakes are especially common with capital gains or losses from stocks or investment trusts, and when combining furusato nozei with the One-Stop Special Exception system. Take another look at your records.
- Key Things to Double-Check
- Is the "Income Tax Withheld" amount on your withholding slip correct?
- Are you double-dipping on your furusato nozei deduction by claiming it both through the One-Stop system and your final tax return?
- For medical expense deductions, have you subtracted any amounts covered by insurance payouts?
- Does your return reflect the information from your Annual Trading Report for specified accounts (stocks/investment trusts)?
Bottom Line: This Year, Early Preparation is Key
The NTA website has become much more intuitive, but in the end, nothing beats carefully verifying everything yourself. Precisely because deduction rules are changing next year, you'll want to get this year's filing done correctly under the current regulations. Expecting e-Tax lines to get congested right before the deadline, now is the perfect time to gather your necessary documents and check out the NTA's final tax return corner. And if you run into trouble, you might be surprised by how helpful the consultation desk at your local tax office can be.
