The Freelancer's Year-End Close: A Weekend Checklist for US 1099 Contractors

If you freelance in the US, December can turn into a scavenger hunt: a missing invoice here, a personal purchase mixed into business expenses there, and a nagging question about whether you owe one more estimated payment. A year-end close is the process of tidying the year's records so they're accurate, complete and easy to hand off. Here's a practical walkthrough you can do in a weekend.

This is general bookkeeping guidance, not tax advice. Rules and dates change, so confirm specifics on IRS.gov or with a tax professional.

Know the two January dates that matter most

Most solo freelancers face two deadlines right after the holidays:

• Q4 estimated tax payment: usually due around January 15 for the prior year's fourth quarter. If you pay quarterly estimates, this is the last one for the year.
• Form 1099-NEC: if you paid independent contractors for business services, 1099-NEC is generally due to both the contractor and the IRS by January 31. When a deadline lands on a weekend or holiday, it typically moves to the next business day.

Put both on your calendar now, and check the exact dates for your tax year on IRS.gov.

Step 1: Gather every export in one folder

Create one folder for the year and download:

• Full-year statements or CSV exports from every account you used for work
• Credit card statements
• Payment platform reports (Stripe, PayPal, Square, Upwork and so on)
• Your invoice list from your invoicing tool or spreadsheet

Pulling everything first avoids the stop-start pattern of hunting for a document halfway through a task.

Step 2: Reconcile income

Make a simple table: invoice number, client, amount, date paid, and where the money landed. Then match each invoice to a deposit. Look for:

1. Invoices marked unpaid that were actually paid, or the reverse
2. Deposits with no matching invoice
3. Platform fees taken before payout. These are usually recorded as gross income plus a separate fee expense.

In January you may receive 1099-NEC or 1099-K forms from clients and platforms. Compare them against your records. Income is generally reportable whether or not a form arrives, so treat your own reconciliation as the source of truth and note any mismatches for your accountant.

Step 3: Categorize expenses

Go through your statements and tag each business expense. Schedule C uses categories such as advertising, contract labor, office expense, supplies, travel, meals, and other expenses (where many people list software subscriptions).

Two habits help:

• Flag anything mixed personal/business, like a phone plan or internet, so a reasonable business-use percentage can be applied.
• Add a short note to anything unusual. "Conference ticket, client prospecting" is far more useful in April than a bare line item.

Step 4: Document home office, mileage and equipment

These are the records people most often under-document:

• Home office: note the square footage of the space used regularly and exclusively for work, plus your home's total square footage.
• Mileage: the IRS expects a log with date, destination, business purpose and miles. If you didn't keep one, reconstruct what you can from calendars and invoices, then start a proper log for next year.
• Equipment: list purchases like laptops, monitors and cameras with date, cost and receipt. Your accountant can advise how they're treated.

Step 5: Handle your own contractors

If you hired subcontractors, you may need to issue them a 1099-NEC. Collect a Form W-9 from each one (ideally before paying them, but now beats January 30) and total what you paid each person. Payments made by card or through platforms like PayPal are often reported by the platform instead, and the reporting threshold has changed recently, so check the current IRS instructions for Form 1099-NEC.

Step 6: Chase unpaid invoices

List anything still outstanding and send a short, friendly follow-up. Note which invoices you've given up on so your accountant can advise on them.

Step 7: Build the accountant handoff packet

Combine everything: a cover sheet with your totals, the income reconciliation, the expense summary, home office and mileage records, the contractor list, and a short list of questions. A tidy packet means fewer back-and-forth emails.

A simple weekend plan

• Saturday morning: gather exports
• Saturday afternoon: reconcile income
• Sunday morning: categorize expenses; document home office, mileage and equipment
• Sunday afternoon: contractors, unpaid invoices, handoff packet
