When Can You File Taxes in 2027? The NETFILE Open Date and 6 Things to Do Now

No date yet. CRA has not announced when NETFILE opens for the 2027 tax-filing season, and anyone giving you an exact date right now is guessing. What CRA has already shown is the shape of the calendar: the 2026 season opened Monday, February 23, 2026 at 6:00 a.m. ET, and based on that pattern, NETFILE for 2027 — when you file your 2026 return — should open in late February 2027, with CRA typically locking in the real date sometime in January. What will not move, whether NETFILE opens on February 20 or March 1, is the April 30, 2027 payment and filing deadline for most Canadians. That date is fixed by statute, not by how quickly CRA finishes certifying that year's tax software.

When Will NETFILE Open for the 2027 Season?

CRA does not announce the NETFILE opening date far in advance — the February 23, 2026 date was confirmed in a filing-season announcement issued January 27, 2026, under a month before the system went live, because the exact date depends on how quickly the agency finishes certifying tax software against that year's budget changes, not on a fixed formula. Here is what the last cycle actually looked like, and what it tells you about the 2027 season:

One detail in that table matters right now, in the middle of 2026: the current NETFILE window is still open. If you have an unfiled original return sitting anywhere from 2018 to 2025, you do not need to wait for the 2027 season to catch up — you can file it electronically today, and that window does not close until January 29, 2027.

The 2027 Tax Deadlines That Do Not Wait for NETFILE

The NETFILE opening date and the actual tax deadline run on two different mechanisms. The deadline is not something CRA decides year to year — it is set out in the Income Tax Act and only shifts when the statutory date lands on a weekend. Here is every 2027 date that is already fixed, whether or not NETFILE has opened by the time you read this:

Notice that two of those deadlines land on the exact same day — March 1, 2027 — because both follow the same underlying rule. T4 slips are due the last day of February, which is a Sunday in 2027, pushing the deadline to the next business day. The RRSP deadline is 60 days after December 31, and in a non-leap year like 2027, that 60-day count also lands on March 1. Neither date depends on NETFILE being open.

Does the NETFILE Opening Date Even Matter to You?

Not equally. If you are expecting a refund, the opening date is the actual gate on when your money moves — CRA cannot start processing your return, let alone issue a refund, before the system goes live, so a later-than-expected opening pushes your whole refund timeline back by exactly as many days. If you already know you owe money, the opening date barely matters: your payment is due April 30, 2027 whether you file the return on February 25 or April 28, and paying an estimated balance through your bank or CRA My Payment does not require NETFILE to be open at all — you can calculate and pay before you have even finished the return.

That distinction is worth sitting with, because most of the anxiety around the exact NETFILE date is a refund-side concern. If your 2026 tax situation did not change much and you already have a rough sense of what you owe or are getting back, the precise opening date is a convenience worth knowing, not a deadline that puts you at risk either way.

What to Do Before NETFILE Opens

None of the six moves below require CRA to have confirmed anything. They are the difference between filing the week your return is ready and filing whenever you finally get around to digging up a missing slip.

Build Your Slips Checklist Now

Start a running list as slips arrive rather than hunting for them in March: T4 (employment income), T4A (pension, scholarship, or self-employed commission income), T5 (investment income), T3 (trust income), T5008 (securities dispositions), RRSP contribution receipts, medical expense receipts, charitable donation receipts, and childcare or moving expense records if either applies to you. Missing even one slip is the single most common reason a return that could have been filed in February does not actually go in until April.

Set Up or Confirm Your CRA My Account

Your CRA My Account shows your notice of assessment history, your RRSP deduction limit, your instalment reminders, your benefit statements, and — once you file — your refund status, all in one place. It is also the fastest way to confirm your T4 is actually on file if a mailed copy goes missing. If you have never registered, do it now rather than in February: full access is not instant, and starting the process during the pre-season lull means you are not waiting on it during the busiest weeks of the year, when call-centre wait times climb along with filing volume.

Confirm Direct Deposit

Direct deposit routes your refund straight to your bank account instead of waiting on a mailed cheque, and it is the same banking information CRA uses for benefit payments like the Canada Child Benefit, GST credit, and OAS. If you have moved or switched banks since you last filed, check that your direct deposit details are current in CRA My Account — our CRA payment dates calendar shows the full list of what else lands in your account on the same rails.

Mark Both March 1, 2027 Deadlines

Your T4 arrival and your RRSP contribution cutoff for the 2026 tax year both land on the same Monday. If you are still deciding how much to contribute before that date, our RRSP deadline strategies guide walks through the last-minute contribution math, including when topping up actually lowers your tax bill and when it does not.

Behind on 2018–2025? File Now — Do Not Wait for 2027

This is the move most people miss. If you have an outstanding original return from any year between 2018 and 2025, NETFILE for those years is open right now and stays open until January 29, 2027. There is no reason to wait for the 2027 season to open before catching up on old returns — doing it now also means any refund or benefit recalculation tied to that filing does not sit in a queue any longer than it has to.

Line Up Your Related 2026 Numbers

If you want to sanity-check what you will actually owe before you file, run your expected 2026 income against our federal tax brackets 2026 breakdown for the exact dollar figure, or read how marginal tax actually works if you are not sure why your entire paycheque is not taxed at your top rate. Self-employed and registered for GST/HST? That return runs on a completely separate calendar from your personal income tax deadline — see our GST/HST return filing dates guide so the two do not collide. And filing your return is also what CRA uses to recalculate benefits like the Canada Child Benefit and the GST credit for the next payment year — our CRA benefit increases breakdown shows how those recalculations flow through.

How You Will Know the Moment NETFILE 2027 Is Confirmed

CRA publishes a "what you need to know for the filing season" announcement every January, and that release is where the real NETFILE opening date shows up alongside that year's deadline reminders and any contribution-limit updates. There is no earlier, more reliable source than that announcement — not a tax software vendor, not a forum post, not a projection like the one in this article. Until then, late February 2027 is the working estimate based on precedent, not a confirmed date.

Everything in the six moves above is worth doing whether NETFILE opens on schedule or a few days later than expected. The deadline that actually matters — April 30, 2027 — is not moving, and the readers who file the week their last slip arrives are never the ones scrambling in the final days of April, hunting for a T5 from an account they forgot they closed or a donation receipt they meant to file somewhere safe.
