Year-End Tax Checklist for a Small Business

The short answer: what most small businesses should do before year-end

If you run a small business, year-end usually means four jobs: clean up your bookkeeping, review payroll, gather tax records, and ask questions before filing season starts.

A practical year-end checklist looks like this:

1. Reconcile bank and credit-card accounts so your books match your statements.
2. Review income and make sure all sales, deposits, and payment-app transfers are recorded correctly.
3. Sort expenses into the right categories and remove personal spending from business books.
4. Check unpaid invoices and unpaid bills.
5. Review payroll totals, contractor payments, and worker classification.
6. Gather receipts and support for big purchases, travel, mileage, home office, and vehicle use if those apply.
7. Count inventory if you sell products.
8. Review assets you bought this year, like computers, tools, furniture, or equipment.
9. Confirm your legal business name, address, EIN, owners, and bank details are current.
10. Get help early from a licensed accountant if anything is unclear.

If your records are messy, do not panic. That is common. The important thing is to get organized now and talk to a CPA or IRS Enrolled Agent before deadlines. BalancedRow is a free matching service. We can help you get matched with a licensed accountant, but we do not prepare returns or give tax advice.

Clean up your bookkeeping before you think about the tax return

Good tax filing starts with clean books. If the bookkeeping is wrong, the tax return may be wrong too.

Here is where many owners get burned:

• Bank accounts not reconciled. Your accounting records should match bank and card statements. If they do not, ask why.
• Personal and business spending mixed together. This creates confusion and can raise red flags.
• Income double-counted or missed. This happens a lot with payment apps, merchant processors, and transfers between accounts.
• Expenses dumped into one category. That makes review harder and can lead to overpaying or underreporting.
• Loan payments recorded as expenses. Often only part may be an expense. The rest may be principal repayment.
• Owner draws and owner contributions misclassified. These should usually not be treated like normal business income or expenses.

Before year-end, go month by month and check:

• bank statements
• credit-card statements
• loan statements
• merchant processor summaries
• payroll reports
• major receipts
• unpaid customer invoices
• unpaid vendor bills

If you use software, make sure the categories make sense in plain English. If you do not use software, even a clean spreadsheet is better than a box of receipts.

If you need help understanding what records matter, read about small-business accounting or bookkeeping. Then compare your options with a licensed accountant. Typical ranges vary by workload and location, but monthly bookkeeping often runs about $150-$600 per month, and an hourly CPA often runs about $150-$400 per hour. The real fee depends on the work involved, your records, your situation, and your area. Always confirm the scope and fee in writing before any work starts.

Review the tax items that are easy to miss

Year-end is not just about adding receipts. It is also about catching issues that can become bigger later.

Payroll and contractors

If you had workers this year, review whether each person was treated correctly. Some businesses pay people as contractors when they should have been employees. That can create tax and payroll problems. Also review year-to-date payroll totals, employee names, addresses, and taxpayer information already on file with your verified provider. If payroll is part of your business, learn what to ask about payroll.

Inventory

If you sell products, count what you still have on hand at year-end. Inventory mistakes can change profit numbers.

Equipment and other assets

Make a list of bigger items you bought for the business this year. Examples: laptops, machinery, office furniture, cameras, tools, vehicles. Save invoices and purchase dates.

Business use of car, phone, and home

These areas are common trouble spots because records are often weak. Keep logs, mileage notes, bills, and a clear explanation of business use if those apply to you.

Sales tax and state notices

If your state or city requires sales tax filings, annual reports, franchise tax filings, or business renewals, do not ignore those notices. Year-end is a good time to make sure your business is current.

Estimated taxes

If your business income changed a lot this year, ask a licensed accountant whether you may need to review estimated tax payments. Do not guess.

Business entity changes

If you formed an LLC, added a partner, changed ownership percentages, or elected a different tax treatment, tell the accountant early. Those changes affect what return may be needed.

This is also a good time to learn the difference between a CPA, an EA, and other preparers. This guide can help: CPA vs EA vs tax preparer.

Get your records ready in one folder

You do not need a perfect system. You need a complete one.

Create one folder for your year-end accountant packet. Paper or digital is fine. Try to include:

• year-end profit and loss statement
• year-end balance sheet, if you have one
• bank and credit-card statements
• payroll reports
• contractor payment totals
• loan statements
• prior-year tax return
• EIN letter or business registration details
• owner names and percentage ownership
• major asset purchase receipts
• inventory count, if relevant
• mileage log, if relevant
• sales-tax reports, if relevant
• notices from the IRS or state agencies
• a list of questions

Then write down anything unusual that happened this year. For example:

• started or closed the business
• moved states
• hired your first employee
• bought or sold equipment
• added a partner
• had a large one-time contract
• used personal money to cover business costs
• took money out of the business often

That short note can save time and reduce mistakes.

Important safety rule: never send your Social Security Number, ITIN number, bank login, account numbers, or tax documents to anyone you have not verified. Verify the accountant's credential and PTIN yourself through the IRS Directory of Federal Tax Return Preparers and, if relevant, your state board of accountancy. BalancedRow only collects contact information and request details for matching. We do not collect SSNs, ITIN numbers, financial-account numbers, or tax documents.

What to do next

If your books are clean and your records are ready, the next step is simple: talk to a licensed accountant early, before filing season gets crowded.

A good process is:

1. Decide what help you need: tax return only, bookkeeping cleanup, payroll review, or broader year-end planning questions.
2. Ask whether the person is a CPA or IRS Enrolled Agent.
3. Verify the credential and PTIN yourself.
4. Ask what documents they need from you.
5. Ask how they charge and get the fee and scope in writing.
6. Keep your sensitive documents until you have verified who you are dealing with.

Typical ranges, not guarantees: an individual tax return often runs about $180-$500. A small-business return often runs about $500-$1,800. The real fee depends on the work involved, your records, your situation, and your area.
