Every year, the IRS announces an official start date for the tax filing season — the first day it will begin accepting and processing electronically filed federal returns. That date matters for anyone planning to file early, expecting a refund, or waiting to begin gathering documents. This guide explains how the filing season opening works, what happens if you try to file before the official date, and how to use the weeks before that date productively.
How the IRS Sets the Filing Season Opening Date
The IRS typically announces the start of filing season in January, usually opening for e-filed returns in mid-to-late January. The specific date varies from year to year depending on how quickly the IRS finishes updating its systems after any late-year tax legislation, form changes, or technical updates from the prior filing cycle.
The opening date applies to electronically filed returns only. Paper returns can be mailed at any time, but the IRS will not process them until the official season opens. For most individual filers, this date marks when their returns enter the IRS processing queue and when any refunds begin moving toward payment.
To find the most current opening date for the current tax year, check the IRS newsroom directly at IRS.gov. The IRS typically releases this date in December or early January.
What Happens If You File Before the Season Opens
Some tax software and tax preparers advertise the ability to “file early” or submit returns before the IRS is accepting them. What actually happens in this case is that the return is queued in the software or preparer’s system and transmitted to the IRS on the first day the agency begins accepting returns. The return is not processed ahead of schedule.
This arrangement has one practical advantage: filers whose returns are queued go to the front of the processing line on opening day, which can accelerate refund timing by a few days. However, it also means the return must be completed and accurate before the season technically opens — there is less time to catch errors or add documents that arrive in late January.
Key Dates to Know Before Filing Season Begins
W-2 Deadline: January 31
Employers are legally required to mail or electronically deliver W-2 forms to employees no later than January 31. If you have not received your W-2 by mid-February, contact your employer’s payroll department first. If you still cannot obtain it, the IRS has a process for requesting a substitute W-2 (Form 4852), which involves contacting the IRS directly and estimating your income and withholding.
Most 1099 Deadlines: January 31 to Mid-February
1099-NEC for nonemployee compensation and most 1099-MISC forms must be sent to recipients by January 31. 1099-INT (bank interest) and 1099-DIV (dividends) are due to recipients by February 15 in most cases. 1099-B (investment proceeds) can arrive as late as mid-March when brokerages need additional time for cost-basis reporting.
IRA Contribution Deadline: Tax Filing Deadline
Contributions to a traditional or Roth IRA for the prior tax year can be made up to the federal filing deadline (generally April 15 for most filers, unless extended). This is one of the few tax-year items that can still be adjusted after December 31 — a point worth raising with a tax professional if you are looking for ways to reduce prior-year taxable income.
California Deadlines
The California Franchise Tax Board generally conforms to federal filing and payment deadlines for individual income tax. When the IRS grants disaster relief extensions, the FTB often follows, but not always automatically — verify current FTB guidance at ftb.ca.gov for any state-specific extensions that may apply to your area.
How to Use the Pre-Season Weeks Productively
The gap between January 1 and the IRS opening date is some of the most valuable time in the tax calendar. Using it well means:
- Booking a preparer appointment. This is the single most time-sensitive action for anyone who relies on a qualified professional. Experienced CPAs, enrolled agents, and licensed California tax preparers (CTEC registrants) fill their available time slots in January and early February. Waiting until March often means settling for a less-experienced preparer or a rushed job.
- Building your document folder. As W-2s and 1099s arrive, add them to a dedicated folder rather than setting them aside. A complete package at the first appointment saves time and reduces the chance of an amended return later.
- Reviewing last year’s return. Pulling out the prior year’s federal and state returns helps identify any carry-forward items — capital losses, net operating losses, prior-year credits — that need to be communicated to your preparer.
- Checking your withholding or estimated payments. If you underpaid during the year, an underpayment penalty may apply. Knowing this in advance lets you discuss it with your preparer rather than being surprised at filing time.
What to Check if You Had a Major Life Change
The tax implications of life events do not always surface at the time they happen — they show up at filing time. Before the season opens, review whether any of the following occurred during the prior year:
- Job change or multiple employers
- Marriage or divorce
- Birth or adoption of a child
- Home purchase or sale
- Retirement or pension distribution
- Death of a spouse or dependent
- Starting or ending a business or freelance work
- Significant investment activity — especially if you used a brokerage account to buy or sell stocks, funds, or other securities
- Moving to, from, or within California (residency rules can affect your FTB filing obligation)
Each of these scenarios has tax implications that a qualified preparer needs to know about. Raising them at the first appointment — rather than mentioning them as an afterthought when the return is nearly complete — produces better results.
Verifying Your Preparer Before the Season Begins
The weeks before filing season is when unqualified and fraudulent “tax preparers” often begin advertising their services heavily. The low-cost or walk-in preparer at a pop-up location may have no credential at all — anyone can call themselves a tax preparer in most states, and while California has stronger requirements than many, enforcement depends on consumers knowing what to look for.
Before the season opens, verify:
- That the preparer has a PTIN (IRS Preparer Tax Identification Number), which is required for all paid preparers
- That the preparer is either a CPA licensed by the California Board of Accountancy, an enrolled agent verified through the IRS, an attorney, or a CTEC-registered tax preparer
- That the preparer will sign the return and include their PTIN — a preparer who declines to sign a return they prepared is a warning sign
Frequently Asked Questions
Does the IRS opening date change every year?
Yes. The IRS sets the date annually based on its system readiness, any late-year legislative changes, and technical preparation. The date is typically announced in late December or early January. Check IRS.gov for the current year’s official opening date.
Can I still file on paper before or after the season opens?
Paper returns can be mailed at any time, but they will not be processed until the IRS is ready to accept them. Electronic filing is faster, more reliable, and typically produces faster refunds. The IRS strongly encourages electronic filing for all individual returns.
What if my employer doesn’t send my W-2 by January 31?
Contact your employer first. If the W-2 does not arrive by mid-February, you can contact the IRS, which will send a reminder to your employer. As a last resort, you can file using IRS Form 4852 as a substitute W-2, based on your best estimate of wages and withholding — but this may require an amended return once the actual W-2 arrives.
Does filing early increase the chance of an audit?
There is no established evidence that filing early triggers more audits. Early filing has the practical advantage of reducing exposure to tax-related identity theft — a fraudulent return cannot be filed in your name if you have already filed your legitimate return for the year.
How early should I contact a tax preparer for an appointment?
As early as January, even before you have all your documents. Many preparers allow you to schedule in advance and collect documents as they arrive. The earlier you are on a qualified preparer’s calendar, the better your options for timing and cost.
