Tax season is only painful when you've left the records until the last minute. The freelancers who dread it are usually the ones reconstructing a year of income and expenses from memory and a messy inbox in early spring. Keep a few things in order as you go and the whole thing becomes an afternoon of confirming numbers you already have.
Here's what's worth keeping records of throughout the year. (This is general guidance, not tax advice — rules vary by country, so check with an accountant for your situation.)
Every invoice you send
Your invoices are the backbone of your income records. Keep a copy of each one, what it was for, and when it was actually paid — which is often a different date than when you sent it. A clean, numbered set of invoices means your total income for the year is a sum, not a guess. If your invoicing is scattered across email drafts and documents, that's the first thing to fix; our invoicing guide covers keeping a proper record.
Your hours, by client and project
Tracked time isn't just for billing. It's a record of the work behind your income, useful if a client or a tax authority ever asks what a payment was for. It also helps you separate business activity from personal time cleanly, which matters when you're claiming a home office or working out what share of a tool or subscription was business use.
Business expenses
The expenses you can deduct are money you don't pay tax on, so missing them is the same as overpaying. Keep receipts and a running list of the obvious categories:
- Software and subscriptions you use for work.
- Hardware — computer, phone, the desk you actually work at.
- A home office or co-working space.
- Professional services like an accountant, plus business insurance.
Log these as they happen. A receipt photographed the day you bought something is a receipt you'll still have in March.
What you set aside for tax
Nobody withholds tax for you when you're self-employed, so it's on you to set aside a portion of every payment — often somewhere around 25–30%, depending on where you live. Keeping a record of what you've put away (and ideally a separate account for it) means the bill is never a surprise. We touched on building this into your pricing in the guide to setting your hourly rate.
Let your day-to-day records do the work
The trick to easy taxes isn't a heroic January cleanup — it's small, consistent records the rest of the year. When your hours, clients, and invoices already live in one place, pulling a year-end summary is a matter of selecting a date range. Gigtime keeps that history together and exports it to CSV or PDF when you or your accountant need it. Try it free — 30-day Pro trial, no credit card required.
