Tax season doesn't have to be a fire drill. Whether you're filing quarterly estimated taxes or preparing your annual return, the secret is the same: stay organized year-round, and do a focused prep before filing.
Here are 7 things every freelancer and small business owner should do before submitting their return.
1. Reconcile All Bank and Credit Card Accounts
Before you look at a single tax form, make sure every bank account and credit card tied to your business is reconciled. That means:
- Every transaction is accounted for
- Your bookkeeping balance matches your bank statement
- No duplicate entries, no missing transactions
If your transactions come from your bank's own record — a bank feed, a CSV export, or, with PennyBot, asking ChatGPT or Grok to record them — most of this is already done. Check for any transactions flagged as "needs review" and resolve them.
Tip: Reconcile monthly throughout the year so tax time is just a quick verification, not a catch-up marathon.
2. Categorize Every Uncategorized Transaction
This is where most small business owners lose time (and money). Uncategorized transactions mean missed deductions. Common categories people overlook:
- Home office expenses — internet, utilities (proportional), office furniture
- Software subscriptions — SaaS tools, cloud storage, design software
- Professional development — courses, books, conferences
- Vehicle expenses — mileage for business travel (more on this below)
- Bank and payment fees — Stripe fees, PayPal fees, bank charges
AI categorization files common merchants on the first pass. But it's worth scanning through your transactions manually to catch anything the AI wasn't confident about.
3. Review and Log Business Mileage
If you drive for business — client meetings, supply runs, co-working commutes — those miles are tax-deductible. The IRS standard mileage rate for 2026 is 72.5 cents a mile for January–June and 76 cents from July 1, 2026. That adds up fast (figures below use the current 76-cent rate over 52 weeks):
| Weekly Miles | Annual Deduction |
|---|---|
| 50 | $1,976 |
| 100 | $3,952 |
| 200 | $7,904 |
The catch? You need records. The IRS requires a log of each trip: date, destination, purpose, and miles driven. If you haven't been tracking, start now — and backfill what you can from calendar entries and Google Maps history.
Mileage tracking tools that integrate with Google Maps can calculate distances automatically based on start and end addresses, making this much easier.
4. Run Your Profit & Loss Statement
Your P&L (also called an income statement) is the single most important document for your tax return. It shows:
- Total revenue — everything you earned
- Total expenses — everything you spent on the business
- Net income — what you actually owe taxes on
Review it line by line. Does every category look right? Is there an expense category that seems too low (meaning transactions were miscategorized elsewhere)? This is your last chance to catch errors before they become part of your tax filing.
5. Check for Estimated Tax Payments Already Made
If you pay quarterly estimated taxes (and as a freelancer, you probably should), tally up what you've already paid. Common places to check:
- IRS Direct Pay or EFTPS payment history
- State tax agency payment records
- Your bank statements for checks written to "United States Treasury"
Subtract your estimated payments from your total tax liability to know what you still owe — or what refund to expect.
6. Organize Supporting Documentation
Even if your bookkeeping is perfect, you need supporting docs in case of an audit:
- 1099 forms from clients who paid you $600+ (2025 income; $2,000+ for 2026 payments)
- Receipts for expenses over $75 (IRS threshold for documentation)
- Bank statements for the full year
- Vehicle mileage log (see step 3)
- Home office measurements if claiming the home office deduction
Store these digitally. A simple folder structure by year and category is fine — you don't need anything fancy.
7. Set Up Next Year's System
The best time to fix your bookkeeping process is right after tax season, while the pain is fresh. Ask yourself:
- Did I have months of uncategorized transactions? → Set up automatic categorization
- Did I forget to track mileage? → Install a mileage tracking tool
- Did I miss quarterly estimated payments? → Set calendar reminders
- Did I spend days reconciling? → Bring transactions in from your bank's own record instead of typing them
The goal is to make next year's tax prep a quick review instead of a multi-day project.
Tracking mileage manually is error-prone. Our mileage tracking guide covers what the IRS requires, and how to log trips properly so your records hold up. For year-round expense capture, automated expense categorization ensures you don't miss deductible costs.
PennyBot automates transaction categorization, tracks business mileage with Google Maps, and keeps your books in sync with your accounting tool — so tax season is a breeze, not a crisis. Get started from $5/month.
Frequently Asked Questions
Can I file my taxes if my books are still messy? You can, but it's expensive and risky. A tax preparer working from messy records spends hours cleaning up your data — and you pay for those hours. Incomplete records during an audit can also result in disallowed deductions. Spending a week cleaning up now beats paying penalties later.
What happens if I've already missed recording some expenses? If the transaction is still in your bank records, you can backfill it — categorize it retroactively and include it in your filing. You'll need documentation of the business purpose. A receipt or email confirmation is ideal; bank statements alone usually aren't enough for the IRS.
How much should I set aside for taxes? Set aside 30% of net income for federal and self-employment taxes. Freelancers with moderate income typically owe 25–30% when federal, self-employment, and state taxes are combined. It's better to overpay estimated taxes than to be surprised at filing.
Do I need to file quarterly taxes? If you expect to owe more than $1,000 when you file annually, the IRS expects quarterly estimated payments. Most freelancers with moderate income file quarterly. Missing payments triggers underpayment penalties — set reminders for April 15, June 15, September 15, and January 15.
