It’s January, which means tax season is officially here. And if you’re like most business owners, you’re about to start gathering documents and sending them to your accountant.
Last week, a client forwarded me an email she’d received from her previous CPA. The subject line read: “Your 2025 Tax Documents.”
Attached to that email, sent through regular Gmail, no encryption, no password protection, were:
- Her complete tax return with Social Security number
- Bank account information
- Investment account statements
- W-2s for all her employees with their SSNs
- 1099s with contractor information
Everything an identity thief would need, sitting in an email inbox accessible to anyone who could guess her password.
I asked her, “Does your email have two-factor authentication enabled?”
“What’s that?”
And there it was. Sensitive financial information, completely unprotected, sitting on servers she didn’t control, accessible to anyone who might hack her email account.
This happens thousands of times a day during tax season. And it’s a disaster waiting to happen.
Why Email Is Not Secure Enough for Tax Documents
Let me be blunt: sending tax documents through regular email is like mailing your Social Security card in a transparent envelope.
Sure, it might get to its destination safely. But along the way, it’s vulnerable to anyone who wants to take a peek.
Here’s what most people don’t realize about email security:
Email Sits on Multiple Servers
When you send an email, it doesn’t go directly from your computer to the recipient’s computer. It bounces through multiple servers:
- Your email provider’s servers
- Potentially multiple intermediate mail servers
- Your recipient’s email provider’s servers
- Backup servers where copies might be stored indefinitely
At each of these points, your email (and its attachments) can potentially be accessed, copied, or intercepted.
Email Providers Can Read Your Messages
Gmail, Outlook, and Yahoo all have the technical ability to read your emails. They need this capability to filter spam, target ads, and comply with legal requests.
Your tax documents? They can see them. Their employees can access them. Their automated systems can scan them.
Are they actively reading your specific emails? Probably not. But the capability exists.
Hacked Email Accounts Are Common
Email accounts get hacked all the time. Phishing attacks, weak passwords, and data breaches at other services. There are countless ways someone can gain access to your email.
Once they’re in, they have access to everything. Every tax document you’ve ever sent or received. Every financial statement. Every piece of sensitive information sitting in your inbox or sent folder.
Email Often Isn’t Encrypted
Most email services use some level of encryption when transmitting messages between servers. But:
- Not all email providers encrypt equally
- Messages are typically decrypted when they reach their destination
- Email sitting in your inbox isn’t encrypted
- Attachments often aren’t separately encrypted
This means your tax documents are sitting in plain text on someone else’s server, potentially for years.
Forwarding Creates New Vulnerabilities
Your accountant might be security-conscious. But what if they forward your documents to someone else on their team? Or what if that person’s email gets hacked?
Every time an email is forwarded, it creates a new potential vulnerability point.
What’s Actually in Your Tax Documents (And Why It Matters)
Let’s talk about what you’re actually sending when you share tax documents:
Personal tax returns contain:
- Full name, address, date of birth
- Social Security numbers (yours, your spouse’s, your dependents’)
- Bank account and routing numbers (if you direct deposit refunds)
- Income sources and amounts
- Investment details
- Detailed financial picture of your life
Business tax returns contain:
- Business EIN
- Business bank account information
- Revenue and expense details
- Employee information
- Owner’s personal information
- Detailed operational data
Supporting documents include:
- W-2s with SSNs
- 1099s with contractor SSNs
- Bank statements with account numbers
- Investment statements
- Mortgage statements
- Healthcare information
This is basically a complete identity theft kit. With this information, someone can:
- File fraudulent tax returns in your name
- Open credit accounts
- Access your bank accounts
- Steal your identity
- Commit wire fraud
- Blackmail you with sensitive business information
Still think it’s fine to email these documents unprotected?
Secure Ways to Send Tax Documents
Okay, so email isn’t safe. What should you use instead?
Option 1: Password-Protected, Encrypted PDFs
If you must use email, at least protect your documents first.
How to do this:
- Combine all your tax documents into a single PDF
- Use Adobe Acrobat, Preview (Mac), or similar software to add password protection and encryption
- Email the encrypted PDF
- Share the password through a different communication channel (text message, phone call, separate secure messaging app)
Why this works: Even if someone intercepts the email, they can’t open the file without the password. And by sharing the password through a different channel, you’re adding a second layer of security.
Limitations:
- Requires both sender and recipient to have compatible PDF software
- Password must still be shared somehow
- If someone has access to both your email and your text messages, they can still get both pieces
Best for: One-time document sharing with someone you trust
Option 2: Secure File Sharing Services
There are several services designed specifically for secure file sharing:
Client portals (like ShareFile, SmartVault, SafeSend)
- Encrypted storage and transmission
- Access controls and permissions
- Audit trails showing who accessed what and when
- Professional appearance
How it works: Your accountant (or you) uploads documents to a secure portal. You log in with a password (and ideally two-factor authentication) to access your documents. Everything is encrypted, and you can see who’s accessed your files.
Why this works:
- Documents never travel through email
- Strong encryption protects files at rest and in transit
- Access can be revoked or controlled
- Professional and compliant with most security standards
Best for: Ongoing relationships with accountants, bookkeepers, or financial advisors
Option 3: Encrypted File Transfer Services
Services like Tresorit, SpiderOak, or Sync.com offer end-to-end encrypted file sharing.
How it works: Files are encrypted on your device before being uploaded. They remain encrypted in storage and during transmission. Only someone with the decryption key (password) can access them. Not even the service provider can read your files.
Why this works:
- True end-to-end encryption
- Zero-knowledge architecture (provider can’t access your data)
- Secure sharing with password protection
- Often more secure than mainstream options like Dropbox or Google Drive
Best for: Maximum security when sharing very sensitive documents
Option 4: Secure Messaging Apps with File Sharing
Apps like Signal or Wire offer encrypted messaging and file sharing.
How it works: Both parties install the app. You send documents through the app’s encrypted messaging system. Messages and files are encrypted end-to-end.
Why this works:
- Simple and user-friendly
- End-to-end encryption
- Can be used on desktop and mobile
- Free for basic use
Limitations:
- Both parties need to have the app installed
- File size limits
- Not designed specifically for document management
- Less professional for business use
Best for: Quick sharing of a few documents with tech-savvy recipients
Option 5: Traditional Physical Delivery
Don’t underestimate the security of physically handing documents to someone or using certified mail.
Why this works:
- No digital vulnerability
- Physical receipt confirmation
- Harder to intercept than email
Limitations:
- Slower
- Less convenient
- Still requires physical security on both ends
Best for: Extremely sensitive documents when you’re local to your accountant
What Your Accountant or Bookkeeper Should Be Using
If you’re working with a professional accountant or bookkeeper, they should already have secure systems in place.
Here’s what to expect:
They should offer:
- A secure client portal for document exchange
- Clear instructions on how to use their system
- Two-factor authentication options
- Encryption for all file transfers
- Professional-grade security measures
Red flags:
- They ask you to email tax documents with no security measures
- They don’t have a secure portal or system in place
- They’re dismissive when you ask about security
- They store your documents on unsecured cloud drives
- They can’t explain their security practices
If your current accountant doesn’t have secure systems, that’s a legitimate reason to find a new one. Tax document security should be a standard professional practice, not an optional extra.
January Tax Prep: What Business Owners Need to Know Right Now
Since we’re talking about tax documents in January, let’s talk about what you should be doing right now to prepare for tax season.
Key January Deadlines for Businesses
January 31, 2026:
- W-2s must be provided to employees
- 1099-NEC forms must be sent to contractors (for non-employee compensation)
- 1099-MISC forms must be sent (for certain other payments like rent)
- Copies of these forms must be filed with the IRS
If you haven’t already completed this, you need to prioritize it immediately. Late filing can result in penalties ranging from $60 to $310 per form, depending on the extent of the delay.
Throughout January:
You should be gathering all your business documents for your annual tax return:
- Bank statements for all accounts
- Credit card statements
- Receipts for major expenses
- Mileage logs
- Depreciation schedules
- Loan documents and interest statements
- Revenue reports
- Expense categorization
Common Tax Prep Mistakes Business Owners Make
Mistake #1: Waiting until the last minute
The most common mistake I see is business owners who wait until March or April to start thinking about their taxes. By then:
- You’ve forgotten details about deductions
- You’re missing receipts or documentation
- Your accountant is slammed and can’t give you attention
- You’re rushed and more likely to make errors
- You might miss opportunities for tax planning
Start now. The earlier you begin, the more time you have to optimize your tax situation.
Mistake #2: Poor record keeping throughout the year
Tax time shouldn’t be when you discover your books are a mess. If your bookkeeping has been neglected all year, you’re about to have a very painful January and February.
Clean books mean:
- Faster tax preparation
- Lower accounting fees
- Better deduction identification
- Fewer questions from the IRS
- More accurate financial picture
If your books aren’t up to date, getting them cleaned up should be your absolute first priority.
Mistake #3: Mixing personal and business expenses
If you’re running personal expenses through your business accounts or vice versa, stop. Now.
This creates:
- Tax compliance issues
- Audit red flags
- Inaccurate financial statements
- Headaches for your accountant
- Potential loss of deductions
Get a clear separation between personal and business finances before tax season gets into full swing.
Mistake #4: Missing easy deductions
Many business owners leave money on the table by not claiming legitimate deductions:
- Home office expenses (if you qualify)
- Vehicle expenses (actual expenses or mileage)
- Professional development and education
- Business insurance
- Software and subscriptions
- Professional services (legal, accounting, consulting)
- Marketing and advertising
- Travel and meals (within IRS guidelines)
Review your expenses carefully. Make sure you’re capturing everything you’re entitled to.
Mistake #5: Not planning for the tax bill
Your business had a great year? Congratulations! Now make sure you’ve set aside enough to pay the taxes on that profit.
A common scenario: A business makes $100K profit and the owner spends it all throughout the year. April comes, and they owe $25K in taxes they don’t have.
If you haven’t been making quarterly estimated tax payments, you need to calculate what you’ll owe and make sure you have the cash available.
Tax Planning Opportunities You Still Have
Even though it’s January, there are still some things you can do to impact your 2025 taxes:
Retirement contributions: You have until April 15, 2026 (or your tax filing deadline) to make IRA contributions for 2025. For self-employed individuals, SEP-IRA contributions can be made until your tax filing deadline, including extensions.
This means you can make substantial retirement contributions that reduce your 2025 taxable income, but you need to do it before you file.
Organizing documentation: Better documentation can help you identify deductions you might have missed or defend deductions if questioned.
Spend time now organizing:
- Receipt files
- Mileage logs
- Expense categories
- Supporting documentation for large expenses
Amending previous returns: If you discover you missed significant deductions in prior years, you can amend returns from the past three years.
January is a good time to review past returns and see if there are opportunities to recover overpaid taxes.
What to Send Your Accountant (And How to Send It Securely)
Here’s what your accountant typically needs:
For your business tax return:
- Profit & Loss statement for the full year
- Balance sheet as of December 31
- Bank statements for all business accounts
- Credit card statements
- Loan documents and year-end balances
- Depreciation schedule from previous year
- Any 1099s you received
- Records of estimated tax payments made
- Any major receipts or contracts for significant expenses
For employee/contractor reporting:
- List of all employees with wages paid
- List of all contractors paid over $600
- Completed W-9 forms from contractors
For your personal return (if applicable):
- W-2s from any employment
- 1099s received
- Mortgage interest statements
- Property tax records
- Charitable contribution receipts
- Other income documentation
How to organize before sending:
- Create folders by category (rather than one giant pile)
- Label everything clearly
- Include a summary document explaining anything unusual
- Make sure everything is readable (no blurry photos of receipts)
- Remove any duplicate documents
Then use one of the secure methods we discussed earlier to get everything to your accountant.
Setting Up Security for Next Year
Don’t wait until next January to think about this again. Set up secure systems now:
For business owners:
- Implement a secure document storage system
- Use a business-grade cloud storage with encryption
- Organize files logically (by year, by category)
- Set appropriate access permissions
- Enable two-factor authentication
- Establish a secure communication protocol with your accountant
- Agree on which secure platform you’ll use
- Set it up and test it
- Make it your standard practice, not just for tax season
- Train your team on document security
- Make sure anyone handling financial documents understands security protocols
- Establish clear policies about email and document sharing
- Regular reminders about security best practices
- Enable two-factor authentication everywhere
- Email accounts
- Bank accounts
- Accounting software
- Cloud storage
- Any financial applications
- Use a password manager
- Strong, unique passwords for every account
- Securely stored and encrypted
- Can be shared with team members who need access
For working with your financial team:
Make sure everyone you work with (accountant, bookkeeper, CFO, financial advisor) has and uses secure systems. If they don’t, that should be part of your conversation when you hire or continue working with them.
The Bottom Line
Tax season is stressful enough without worrying about identity theft or data breaches.
Your tax documents contain some of the most sensitive information about you and your business. Treating them casually, like emailing them unencrypted, is a risk you don’t need to take.
Secure alternatives exist. They’re not complicated. They’re often free or very low-cost. And they give you peace of mind that your information is protected.
So this tax season, do yourself a favor:
Stop emailing tax documents unprotected.
Set up a secure sharing method with your accountant.
Take a few extra minutes to protect your information.
Because the hassle of using secure file sharing is nothing compared to the nightmare of dealing with identity theft or a data breach.
And while you’re at it, get your 2025 tax documents organized now. Don’t wait until March when everyone is scrambling.
The earlier you start, the less stressful tax season will be, and the better positioned you’ll be to minimize your tax bill and maximize your deductions.
