Tax season doesn't have to feel like a looming disaster waiting to happen. With a little proactive organization and the right mindset, even the most chaotic financials can be brought into order—without the last-minute stress.
This guide will walk you through how to prepare for tax season step-by-step, specifically designed for small business owners and startup founders.
1. Start With Clean Books
Before you worry about forms and filings, your books must be in order.
What to review:
Bank & credit card reconciliations:
Ensure every transaction is matched and explained.
Income categorization:
Double-check that revenue is mapped correctly (especially if you use Stripe, PayPal, etc.)
Expense classifications:
Advertising, software, travel, meals, etc. should be cleanly tagged.
Example: If you bought a new laptop, it shouldn’t be lumped into “Office Supplies.” It belongs under “Fixed Assets,” which may be depreciated over time.
2. Organize Your Supporting Documents
Even in the digital age, supporting documentation is critical.
Key records you should have ready:
Receipts and invoices (organized by category/vendor)
W-9s from contractors
1099s issued
Loan documents
Asset purchase receipts
Year-end bank statements
Pro tip: Use tools like Hubdoc or Dext to snap and categorize receipts automatically.
3. Know What Forms You’ll Need
Your tax filing depends on your business structure:
Entity Type | Main Tax Form | Notes |
Sole Proprietor | Schedule C (Form 1040) | Personal return with business income |
LLC (Single Member) | Schedule C (Form 1040) | Same as sole prop |
LLC (Multi-Member) | Form 1065 + K-1s | Partnership return |
S-Corp | Form 1120S + K-1s | Must pay yourself “reasonable salary” |
C-Corp | Form 1120 | Separate business entity |
Reminder: If you run payroll, Form 941 (quarterly) and Form W-2 (year-end) are mandatory.
4. Understand Common Tax Deductions
Knowing what you can deduct helps reduce your taxable income.
Some high-impact deductions:
Software subscriptions (e.g. QuickBooks, Zoom, Canva)
Home office use (proportional rent, utilities)
Mileage for business travel
Professional services (accountants, legal, consultants)
Startup costs (up to $5,000 in first year under IRS Sec. 195)
Anecdote: One founder realized they forgot to deduct $15,000 in contractor expenses—just because it wasn’t coded properly in QuickBooks. Fixing it slashed their tax bill.
5. Work With a Tax Professional
Unless you’re a CPA, don’t DIY your taxes at scale.
What a good accountant will help with:
Strategic tax planning (not just filing)
Maximize deductions, legally
Ensure GAAP compliance
Avoid penalties from IRS audits or missed deadlines
Tip: Schedule your meeting before March, so there’s time to fix any issues.
6. Track Key Tax Deadlines
Deadline | Form/Requirement |
Jan 31 | Send 1099-NECs to contractors |
March 15 | File S-Corp or Partnership returns (or request extension) |
April 15 | File C-Corp or Sole Prop/LLC returns (or request extension) |
Quarterly | Pay estimated taxes (Form 1040-ES or 1120-W) |
Missed a deadline? File an extension (Form 7004 or 4868) — but remember: it gives you more time to file, not to pay.
7. Store & Backup Everything
IRS rules require you to keep records for 3-7 years, depending on the document.
Best practices:
Use cloud storage like Google Drive or Dropbox
Name files clearly: VendorName_Invoice_2024-03.pdf
Create folders by year → category → month
📦 Bonus tip: Archive everything into a single zip folder post-tax season and label it “2024 Taxes – FINAL.”
Bonus: Pre-Tax Season Checklist (Copy & Paste)
Here’s a simplified version of what to do before your tax appointment:
✅ Books reconciled
✅ Receipts uploaded & tagged
✅ W-9s collected from all contractors
✅ Payroll forms filed (W-2s, 941s)
✅ Deductions reviewed
✅ Entity-specific tax deadlines calendared
✅ Met with accountant
✅ Files backed up
