Filing season has a fixed start and a fixed deadline. The preparers who work those 10 weeks without fire drills are the ones who finished October through December with every credential renewed, every system tested, and every compliance obligation checked off before the first client walked in.
This checklist covers the full annual cycle: year-end credential and compliance tasks (October through December), pre-season technical and operational setup (January), the active filing season (January through April), and off-season planning (May through September). If you are starting your practice for the first time rather than managing an ongoing one, see the companion guide: How to Start a Tax Preparation Business.
Each item below links to the deeper reference guide where the procedural detail lives. Use this page as your calendar prompt; use the linked guides when you need the full walkthrough.
Phase 1: Year-End Preparation (October through December)
October through December is the window when the IRS opens PTIN renewal, continuing education deadlines converge, and software licenses for the upcoming season go on sale. Miss this window and you are either scrambling in January or operating out of compliance. Complete all of the following before December 31.
Renew Your PTIN
Deadline: December 31. Every paid preparer who signs a federal return must hold an active PTIN. Renewal opens in mid-October at the IRS Tax Professional PTIN System. The current fee is $18.75. You will need to verify your identity through ID.me if you have not done so previously. A lapsed PTIN means you cannot legally prepare paid returns until you renew.
Set a calendar reminder in the first week of October so you are not rushing during what is otherwise a quiet preparation month. See the full PTIN renewal guide for a step-by-step walkthrough, including the ID.me verification process.
Complete AFSP Continuing Education (If Pursuing AFSP)
Deadline: December 31. The IRS Annual Filing Season Program requires 18 CE hours for most non-exempt preparers: 10 hours of federal tax law topics, 2 hours of ethics, and 6 hours of federal tax law updates including the Annual Federal Tax Refresher (AFTR) course and test. All hours must be completed by December 31 to earn the record of completion for the upcoming filing season.
AFSP is voluntary, but it earns you a listing in the IRS Tax Pro Directory and grants limited representation rights before the IRS on returns you prepared and signed. Starting CE in October gives you time to work through hours without compressing everything into December. See the full AFSP guide and browse available courses at ATP Courses.
Review and Update Your WISP
The FTC Safeguards Rule requires an annual review of your Written Information Security Plan. Your WISP documents how you protect client data: access controls, encryption, incident response procedures, and vendor management. An annual review is not optional language; it is a legal requirement for covered financial institutions, which includes most tax preparation businesses.
Do not treat the WISP as a one-time document. Update it to reflect any changes to your software, hardware, storage practices, or employee roster from the prior year. See the tax preparer data security guide for WISP requirements and a template framework.
Purchase or Renew Your Tax Software License
Software licenses for the upcoming season are available before January. Do not wait until January to order; software delivery, installation, and initial testing takes time, and you want that time before clients arrive. TaxWise is available through America's Tax Professionals for the 2026 season, covering individual 1040 returns, business returns, and all-states e-file through ATP's IRS-authorized transmission network.
If you are considering a change from your current software, the off-season (May through September) is when to demo alternatives, not December. December is for executing the decision you already made. See ATP software options.
Enroll with Your Bank Product Partner
If you offer refund transfers, refund advances, or other financial products to clients, your bank product partner requires enrollment before the filing season opens. Enrollment windows close before January in most cases. A missed enrollment means your clients cannot access these products for the entire season.
Bank products are one of the most meaningful value-adds an independent preparer can offer, particularly for clients who cannot afford to wait for a standard refund. See ATP bank products for enrollment details.
Renew Errors and Omissions Insurance
Verify that your errors and omissions (E&O) coverage is active and sufficient for the upcoming season before you prepare the first return. Policy lapses and coverage gaps are not discovered until a claim is filed, which is too late. Review your coverage limits, per-claim deductibles, and whether your policy covers all return types you plan to prepare.
See the tax preparer insurance guide for a breakdown of coverage types relevant to independent preparers.
State-Specific Credential Renewals
Two states have year-end renewal deadlines that do not align with the standard December 31 PTIN date.
California (CTEC): CTEC registration renewal deadline is January 15. California non-exempt preparers who miss this date are not authorized to prepare California state returns. Complete your 20 CE hours and submit your CTEC renewal before the January 15 deadline. See the full California tax preparer requirements guide.
New York: New York requires non-exempt preparers to renew their annual registration with the New York Department of Taxation and Finance. Confirm the current renewal window and deadline with the NY Tax Department, as dates and requirements are subject to change. See the New York tax preparer requirements guide.
Phase 2: Pre-Season Setup (January)
January is the last week of setup before returns start arriving. Use it to verify that every technical system is working, every credential is confirmed active, and every client-facing process is ready for the season. Do not let the first client return be the first real test of your e-file connectivity.
Install Software and Run Test Returns
Install your 2026-season software, run the initial update cycle, and prepare at least one complete test return before the first client appointment. Test returns verify that your e-file connectivity is working end to end, that your state modules are installed, and that your bank product integration (if applicable) is active.
A test return takes 30 minutes. Discovering a misconfigured transmission on a live return during filing season costs far more than that. If you are new to TaxWise, see the software downloads page for installation resources.
Verify IRS e-Services Account and EFIN Standing
Log into your IRS e-Services account before the season opens to confirm your account is active, your EFIN is in good standing, and your contact information is current. An inactive e-Services account or a problem with your EFIN shows up as a transmission rejection, not a warning in advance.
If your EFIN application is still in progress, the process takes up to 45 days; submit well ahead of the January opening date. For the complete EFIN application walkthrough, see the EFIN guide.
Confirm E-File Mandate Compliance
If you reasonably expect to prepare 11 or more individual returns this season, you are subject to the IRS e-file mandate and must file those returns electronically. If a client requests a paper return, you must attach Form 8948 to document the reason. If your practice has grown to the point where the mandate applies for the first time, confirm your EFIN is active and your software is configured to e-file before the first return arrives.
See the IRS e-file mandate guide for the full threshold rules, Form 8948 instructions, and hardship waiver process.
Verify ATP Transmission Setup (ATP Clients)
If you transmit through America's Tax Professionals as your IRS-authorized service bureau, confirm your transmission account is active and your EFIN is on file with ATP before the season opens. ATP operates as the IRS-authorized intermediary between your software and the IRS; a setup problem on our end or yours creates a delay that affects your clients.
Contact ATP directly to confirm your setup or see the e-file services page and service bureau overview.
Update Client Intake Forms and Privacy Notices
Engagement letters, consent forms for disclosure or use of tax return information (required under IRC Sections 7216 and 6713), and privacy notices must reflect the current tax year. Generic or prior-year forms expose you to liability. Update your standard engagement letter, your Form 8821 or 2848 templates if you carry POA for clients, and any consent forms for sharing data with third parties (including bank product partners).
Your secure client portal and document collection process should also be tested before the season. If you are collecting documents digitally, verify that the portal is accessible to clients and that files route correctly to your local system.
Confirm State Registration is Active
If you practice in California, Maryland, New York, Oregon, or Connecticut, verify that your state registration is current before you prepare the first return. Preparing returns in a mandated state without an active registration is a compliance violation, not just an administrative oversight. For a full breakdown by state, see the tax preparer requirements by state guide.
Phase 3: Filing Season (January through April)
The filing season is execution, not setup. The items below are the operational checkpoints that prevent the most common mid-season problems: client expectation mismatches, missed deadlines, and documentation gaps.
Set Client Expectations on IRS Processing Times
For the 2026 filing season, IRS e-file processing is running 3 to 5 weeks rather than the standard 21-day window. Clients who expect a refund in three weeks and do not hear from you will call. Get ahead of it: explain the processing timeline at the intake appointment and follow up proactively with clients if a refund is delayed beyond their expected date.
Clients using bank products (refund advances) receive funds through a separate channel that does not depend on IRS processing completing first, which is a meaningful distinction to explain to clients who are counting on a specific date.
Follow Bank Product Submission Workflows
For clients using refund advances or refund transfers, follow your bank product partner's enrollment and submission process precisely. Each product has its own application requirements, ID verification steps, and disbursement timeline. Errors in the bank product submission process can result in delayed funds for clients and rejected applications that cannot be corrected after the fact.
See the bank products workflow guide for a detailed submission checklist.
Track Key E-File Deadlines
The critical dates for the 2026 individual filing season are:
- January 27, 2026: IRS e-file season opens for individual returns
- April 15, 2026: Individual return filing deadline (Form 1040 and balance due)
- October 15, 2026: Extended return deadline for clients who filed Form 4868
Business return deadlines follow a different calendar. For a complete list of federal e-file deadlines including business returns and state-specific dates, see the e-file deadlines guide.
Document Paper-Filing Requests with Form 8948
When a client who is subject to the e-file mandate requests a paper return, you must attach Form 8948 (Preparer Explanation for Not Filing Electronically) to that return and keep the client's written authorization in your files. Do not paper-file a return under the mandate without this documentation in place. Unexplained paper filings from a mandatory e-filer are a compliance flag.
Phase 4: Off-Season Planning (May through September)
May through September is the period most preparers spend recovering from filing season. It is also the window that determines how the next season goes. The preparers who use this time well show up in October with their CE partially done, their software decision made, and their business strategy updated. The ones who defer it all until October are behind before the renewal window opens.
Plan Your CE Hours
Get your CE hours started before October rather than completing them all in November and December. The AFSP requires 18 hours by December 31. Enrolled agents are required to complete 16 hours of CE per year (72 hours per three-year renewal cycle, with a minimum of 16 per year), including 2 ethics hours annually. If your state has its own CE requirement, stack the state hours against the AFSP or EA requirement to avoid doubling up.
See the full breakdown by credential in the CE requirements guide. Browse courses available for credit at ATP Courses.
Evaluate Software for Next Season
If you are considering switching tax software, the off-season is when to demo alternatives, compare transmission costs, and make the decision. Switching software mid-season or in December creates data migration problems and training pressure when you can least afford it. Demo products in June or July, make a final decision by August, and have your license in hand before October.
See the TaxWise comparison guide and the ATP software page for current pricing and options.
Archive Client Files per IRS Retention Guidelines
The IRS recommends that preparers retain copies of returns and supporting documents for at least three years, which aligns with the standard assessment statute of limitations. That period extends to six years if more than 25% of gross income was omitted, and there is no time limit in fraud cases. Many practices retain files for seven years as a conservative standard.
Archive the prior season's files to your long-term storage system (encrypted external drive, secure cloud storage, or both) so your active working directory stays manageable and secure. Update your WISP to reflect any changes to your storage infrastructure.
Review Business Insurance
After a full filing season, you have a clearer picture of your practice's actual exposure: return volume, client types, and any issues that arose. Use that information to review your E&O coverage limits, general liability, and cyber liability coverage before the next renewal cycle. Your insurer's requirements and available coverage options may have changed as well.
See the tax preparer insurance guide for a breakdown of coverage types and what independent preparers typically need.
Review Revenue, Fees, and Growth Strategy
Compare your actual season results against your prior-year plan: client count, return volume, revenue per client, and time per return. If you underpriced complex returns or lost clients to a competitor, now is the time to adjust your fee structure for next season rather than mid-season when clients are already in the queue. The same applies to evaluating new services (business returns, ITIN processing, bank products) that you did not offer this year.
For fee benchmarks and pricing strategy, see the tax preparation fee guide. For client acquisition strategies heading into the next season, see the guide to getting tax clients and the tax business marketing guide.
Frequently Asked Questions
When does PTIN renewal open each year?
The IRS typically opens the PTIN renewal window in mid-October for the following filing season. The renewal deadline is December 31. The current fee is $18.75, payable at the IRS Tax Professional PTIN System. First-time renewers must complete ID.me identity verification before renewing. If your PTIN lapses past December 31, you cannot legally prepare paid returns until you complete renewal. Verify current fees and open dates at IRS.gov, as both are subject to change.
What is the AFSP and how many CE hours does it require?
The IRS Annual Filing Season Program is a voluntary continuing education program for non-credentialed preparers. Completing it earns an IRS record of completion, a listing in the IRS Tax Pro Directory, and limited representation rights on returns you prepared and signed. Most non-exempt preparers must complete 18 CE hours annually: 10 hours of federal tax law topics, 2 hours of ethics, and 6 hours of federal tax law updates including the Annual Federal Tax Refresher (AFTR) course and test. All 18 hours must be completed by December 31. AFSP does not confer an EA, CPA, or attorney credential. See the full AFSP guide for details.
What is a WISP and am I required to have one?
A Written Information Security Plan is a documented plan describing how your practice protects client data. The FTC Safeguards Rule requires tax preparers who qualify as financial institutions under its scope to maintain and annually review a WISP. The IRS also strongly recommends a WISP for all tax professionals, regardless of size. Even a solo preparer working from a home office holds sensitive client data that creates real liability without a documented security plan. Update your WISP before each filing season. See the data security guide for a WISP framework.
What is the IRS e-file mandate and how many returns trigger it?
The IRS e-file mandate requires preparers who reasonably expect to file 11 or more individual income tax returns in a calendar year to file those returns electronically. If a client requests a paper return, you must attach Form 8948 to document the reason and retain the client's written authorization. Preparers who cannot comply for an entire practice may apply for a hardship waiver using Form 8944. The mandate applies to individual returns; separate thresholds and requirements apply to business returns. See the e-file mandate guide for the full rules and form instructions.
How long should I keep client tax files?
IRS guidance generally supports retaining copies of returns and supporting documents for at least three years, which aligns with the standard assessment statute of limitations. That period extends to six years if a return omits more than 25% of gross income, and there is no time limit in fraud cases. Many practices retain files for seven years as a conservative standard. Consult current IRS guidance and your professional liability insurer for the retention policy appropriate to your practice, as requirements can vary by return type and jurisdiction.
