January is the best month to get ahead of tax season, not behind it. By the time most people start thinking about taxes, the best appointment slots with experienced preparers are already gone. A simple checklist worked through in the first weeks of the new year can prevent last-minute scrambling, missed deductions, and the kind of costly errors that come from handing over a stack of unsorted paperwork the week a return is due.
This guide walks through what to gather, what to verify about any professional you plan to use, and what changes for the tax year just ended that affect typical individual filers.
Why January Is the Right Time to Act
Tax preparers — especially qualified ones — fill their schedules early. A CPA or enrolled agent in California who is good at their job rarely has open slots after the first week of February, and by March the pressure on their time has pushed fees higher and turnaround times longer. Getting in early also means there is time to track down any missing document, respond to a preparer’s questions, and avoid rushing into an extension.
January is also when documents start arriving. W-2 forms are legally required to reach employees by January 31. Most 1099 forms follow by mid-February. Some forms — including 1099-B for investment sales — can legitimately arrive as late as mid-March. Knowing what to expect means you will notice when something is missing.
The Core Documents to Gather
Income Records
- W-2 forms from every employer you worked for during the year. If you held multiple jobs, you need a W-2 from each one.
- 1099-NEC or 1099-MISC forms for any freelance, consulting, or independent contractor work. If you used a platform such as Upwork, Fiverr, or similar services, check whether you should receive a 1099-NEC from the platform or from individual clients.
- 1099-K if you received payments through third-party payment networks (PayPal, Venmo for business, Square, Stripe). Thresholds and reporting rules have changed in recent years — confirm with IRS.gov what applies to your situation for the most recent tax year.
- 1099-INT and 1099-DIV for interest and dividend income from bank and investment accounts.
- 1099-B for proceeds from stock, fund, or other investment sales. Brokerages issue these, sometimes in a consolidated 1099 package.
- SSA-1099 if you received Social Security benefits.
- 1099-R for retirement account distributions or pension income.
- K-1 forms from any partnership, S corporation, or trust you have an interest in. These often arrive late — sometimes not until March or April.
Deduction and Credit Records
- Mortgage interest statement (Form 1098) from your lender
- Property tax payment receipts or account statements from your county assessor
- Records of charitable contributions — both cash (bank statements or credit card receipts) and non-cash (written acknowledgment from the organization for donations over $250)
- Receipts or records for unreimbursed business expenses if you are self-employed or run a home office
- Childcare or dependent care expenses, including the name, address, and Tax ID number of any provider
- Education expenses — tuition statements (Form 1098-T) and records of qualified education loan interest (Form 1098-E)
- Health insurance premium records if you purchased coverage on your own and may qualify for the Premium Tax Credit
- Documentation for any energy efficiency home improvements made during the year that might qualify for a federal or California credit
Prior-Year Returns and Carry-Forward Items
Bring a copy of last year’s federal and California returns. A good preparer uses these to check for carry-forward items — capital loss carryovers, net operating losses, unused credits — that could reduce your current-year liability. If you switched preparers, your previous preparer is legally required to provide a copy of your return upon request.
Verify Your Preparer Before You Hand Anything Over
January is also when the unqualified and fraudulent preparers advertise heavily. The IRS does not license most tax preparers, which means anyone can hold themselves out as a tax professional regardless of experience or training. Before you share any personal or financial documents:
- Ask for their PTIN. Every paid preparer is required by federal law to have a Preparer Tax Identification Number. You can verify it at the IRS PTIN lookup tool. A preparer who refuses to provide their PTIN or cannot be found in the directory is a serious warning sign.
- Check their credential. In California, paid preparers who are not CPAs, attorneys, or enrolled agents are required to register with the California Tax Education Council (CTEC). You can verify CTEC registration at ctec.org. CPAs can be verified through the California Board of Accountancy. Enrolled agents can be verified through the IRS Enrolled Agent database.
- Confirm representation rights. Only CPAs, attorneys, and enrolled agents can represent you before the IRS if your return is audited. CTEC registrants and AFSP participants have limited representation rights only.
What to Discuss at Your First Appointment
Come prepared with more than just documents. Your first meeting is an opportunity to identify tax-saving strategies before the year closes — although most planning opportunities for the prior year end on December 31, some (like IRA contributions) remain available through the filing deadline.
Bring up any life changes from the prior year: a new job, a home purchase or sale, a marriage, divorce, birth or adoption of a child, an inheritance, a business started or closed, or a significant investment transaction. Each of these has tax implications that a qualified preparer needs to know about to prepare an accurate return.
If you are self-employed or made significant estimated tax payments, bring records of what you paid and when. Underpayment penalties can apply if estimated payments were insufficient, and your preparer needs the full picture to assess your situation.

A Note on California-Specific Considerations
California does not conform to all federal tax rules, which means your state return can produce a different result even with identical underlying income. Among the common differences: California taxes Social Security income differently from the federal government, does not recognize the federal deduction for student loan interest in the same way, and has its own credits and limitations that do not map one-to-one to federal forms.
If you are using a preparer for the first time, confirm they are familiar with California Franchise Tax Board rules, not just federal rules. A preparer who primarily serves clients in another state may not be current on FTB requirements, filing procedures, or California-specific credits.
Frequently Asked Questions
When should I book a tax preparer appointment for the current filing season?
As early in January as possible. Qualified preparers — especially CPAs and enrolled agents — fill their available slots quickly once W-2s and 1099s start arriving. Waiting until February or March limits your options and can mean higher fees for rushed work.
What if I haven’t received all my tax documents by mid-January?
W-2s are legally due to employees by January 31. Many 1099 forms follow by mid-February, though some (like 1099-B for investments) can arrive through mid-March. Contact the issuer if a form is overdue. Your preparer can file for an extension if necessary, but that does not extend the time to pay any tax owed.
Can I start gathering documents before my appointment?
Yes, and doing so makes the process more efficient. Create a folder — physical or digital — and add documents as they arrive. Giving your preparer a complete, organized package reduces the chance of errors and may lower the time-based portion of their fee.
How far back should I keep prior-year returns?
The IRS generally has three years from the filing date to audit a return, but that extends to six years if income was significantly underreported. Keeping at least seven years of records is a common and defensible practice. California’s statute of limitations for FTB audits can extend longer in some cases — your preparer can advise on your specific situation.
Is it safe to email my tax documents to a preparer?
Ask your preparer about their document security practices before sending anything sensitive. Many qualified preparers use an encrypted client portal rather than standard email. Sending Social Security numbers, income figures, and financial account details over unencrypted email creates unnecessary risk. A preparer who cannot explain how they secure your data is a reason to look elsewhere.
