Catch-up bookkeeping checklist: Your end-of-year plan for tackling overdue tasks

80 hours.

That’s the average time small business owners spend on bookkeeping each year^[1]. But if you’re like most, a lot of that time gets crammed into the final weeks of December.

As the year wraps up, you’re probably facing stacks of receipts, unpaid invoices, and uncategorized expenses. The year-end scramble is something every small business owner knows too well.

Here’s the reality: catching up on your books isn’t just about easing tax season stress (though that’s a huge plus). It’s about getting your business set up for a strong start to the new year. When your books are up to date, you can maximize tax deductions, avoid IRS penalties, and gain a clear view of your cash flow.

In this guide, we’ll break down the essentials of catch up bookkeeping, helping you close out the year organized and ready for growth.

Step 1: Gather all financial documents from the year

Before beginning with your catch-up bookkeeping checklist, you’ll first need to round up all your financial documents from the past year. Nothing can be left out if you want a complete and accurate picture when it’s time to close the books.

Here’s what you’ll need:

• Bank statements: Ensure you have statements from all your business bank accounts, covering every month of the year.
• Credit card statements: Collect statements from any business-related credit card transactions. If you’ve used multiple cards, gather statements for each one.
• Invoices and receipts: Pull together all invoices sent to customers and any receipts from business purchases—whether they’re filed away digitally or kept in physical form.
• Payroll records: If you have employees or contractors, gather payroll records, including payments made, taxes withheld, and any benefits provided.
• Loan and mortgage documents: If your business has outstanding loans or a mortgage, gather those statements to ensure all interest payments are accounted for.
• Tax forms: Be sure to have copies of all tax-related forms, like estimated tax payments and 1099 forms for contractors.

Having these documents organized now will save you from a last-minute rush when it’s time to finalize your year-end reports. Plus, it ensures you don’t miss out on crucial tax deductions or make errors that could result in penalties.

Step 2: Reconcile bank and credit card statements

Once you’ve gathered all your financial documents, the next step is reconciling your bank and credit card statements. This step is key to ensuring your books match your actual bank account and credit card balances. If the numbers don’t line up, now’s the time to find and correct the discrepancies.

For small business owners, reconciling accounts at year-end is a must. Here’s why:

• Accurate balances: Reconciling ensures that all your transactions are accurately recorded. If you’ve missed an expense or a deposit, your balances won’t reflect reality, and this could affect everything from cash flow projections to tax filings.
• Catch errors early: You might find errors like double entries or forgotten transactions. These issues can throw off your books and create headaches during tax season.
• Prevent over- or under-reporting income: By making sure your statements are in sync, you’ll avoid mistakes that could lead to under-reporting income (which could lead to IRS trouble) or over-reporting (which could make you pay more in taxes than you need to).

How to reconcile:

1. Compare each transaction on your bank and credit card statements with the entries in your accounting software or records.
2. Identify any mismatches—whether it’s missing transactions, duplicates, or incorrect amounts.
3. Fix discrepancies by adjusting your records or reaching out to your bank or credit card provider to get things sorted.

Step 3: Review and categorize all transactions

Once your bank and credit card statements are reconciled, review and categorize every transaction from the year. Proper categorization helps you understand your business’s spending and can also maximize your deductions when filing taxes.

Here’s what to focus on:

• Income: Separate your income streams by service or product. Whether you’re offering multiple services or selling different products, clearly categorizing income ensures your financial reports reflect the full picture of your revenue.
• Expenses: Break down your expenses into categories like office supplies, utilities, marketing, equipment, and travel. This also helps when claiming deductions, as certain expenses may qualify for tax relief (e.g., business travel or equipment depreciation).
• Separate personal and business expenses: If you’ve accidentally mixed personal and business transactions throughout the year, now’s the time to correct it. Keep in mind that commingling personal and business expenses can lead to confusion during tax filing—and could even raise red flags with the IRS.

Tax-deductible categories: Focus on properly categorizing expenses that can qualify as deductions, such as office supplies, mileage, business meals, or home office expenses. You’ll want to maximize your deductions to lower your tax liability.

You can use tools like QuickBooks or Xero^[3] to help automate this process, making it easier to sort transactions and avoid human error.

Step 4: Prepare for tax filings (W-2s, 1099s, etc.)

As the year comes to a close, one of your top priorities is making sure all your tax forms for employees and contractors are prepared and filed correctly. This might feel like a lot, but knocking it out now will save you a ton of stress (and potential fines) later.

Here’s what you need to do:

W-2s for employees: If you have employees, you’ll need to prepare and file W-2 forms. These forms summarize an employee’s earnings for the year and must be sent to both the IRS and the employee. Make sure you’ve accounted for all payroll taxes withheld and any benefits provided throughout the year.

1099s for contractors: If you’ve paid any independent contractors $600 or more during the year, you’re required to file a 1099-NEC form to report those payments to the IRS. This form is how the IRS tracks income paid to contractors. To complete the 1099-NEC, make sure to request a W-9 form from each contractor, which provides their taxpayer identification number and other essential information.

• Estimated tax payments: If you’ve been making estimated tax payments throughout the year, make sure they’re all recorded correctly. This will ensure you’re on track when filing your annual return and avoid underpayment penalties.
• State-specific filings: Be aware of any state-specific tax forms you may need to file in addition to federal forms. Different states have different requirements, so be sure to check if your state has its own filing deadlines or forms.

Step 5: Review accounts receivable and payable

Now it’s time to take a close look at your accounts receivable (what you’re owed) and accounts payable (what you owe). This step makes sure your year-end financials reflect any outstanding payments and helps you clean up your books before tax season hits.

Here’s how to approach it:

Accounts receivable (AR): Go through all outstanding customer invoices. If any clients still owe you money for services or products, follow up with them before the year ends. If it seems unlikely that you’ll get paid, consider writing off the amount as bad debt—it can lower your taxable income and reduce your tax liability.

Let’s say you run a local marketing agency and have a client who hasn’t paid their $2,000 invoice for services provided three months ago. Despite multiple follow-ups, payment hasn’t come through. Instead of carrying this uncollectible invoice into the new year, you might consider writing it off as a bad debt. This write-off reduces your taxable income, which could mean a lower tax bill for your business.

• Accounts payable (AP): Review all bills from vendors, suppliers, and service providers. Make sure that any payments you owe are reflected in your financial records, and settle outstanding bills if possible. By paying off these amounts before the end of the year, you can deduct the expenses, reducing your taxable income.
• Handling bad debt: If some invoices remain unpaid, consider whether it’s worth pursuing collections or writing them off as bad debt. Writing off bad debt allows you to deduct the uncollected amount, which can be helpful in lowering your taxable income for the year.

Step 6: Generate year-end financial reports

Now that your transactions are categorized and your accounts are reconciled, it’s time to generate your year-end financial reports. These reports will give you a clear snapshot of your business’s financial health and are essential for tax filing, decision-making, and future planning.

Here are the key reports you’ll want to generate:

• Profit and loss statement (P&L): This report shows your total income and expenses for the year, giving you a clear picture of your profitability. It’s essential to determine how much tax you’ll owe and identify any areas where you may need to cut costs or increase revenue in the coming year.
• Balance sheet: The balance sheet provides an overview of your business’s assets, liabilities, and equity at year-end. It’s a critical report for understanding your business’s overall financial position, which can help when applying for loans or attracting investors.
• Cash flow statement: This report tracks how cash has moved in and out of your business over the year. It’s a great way to see how well you’ve managed your cash flow and spot any potential gaps you need to address.
• Accounts receivable and payable aging reports: These reports show outstanding invoices and bills, broken down by how long they’ve been overdue. They’re useful for identifying slow-paying customers and making sure you’ve accounted for all outstanding payments and liabilities.

Step 7: Maximize tax deductions and credits

One of the biggest perks of year-end catch up bookkeeping?

You can make sure you’re taking full advantage of every tax deduction and credit available. This is your chance to review all your expenses and make sure you’re not leaving any money on the table when it comes to lowering your tax bill.

Here’s where you should focus:

• Business expenses: Go through your categorized expenses and make sure you’ve captured everything that qualifies as a deductible business expense. This includes office supplies, marketing, business meals, and travel. Be sure every expense is properly documented with receipts.
• Home office deduction: If you work from home, you might be eligible for the home office deduction. This lets you deduct a portion of your home-related expenses, like rent and utilities, based on the percentage of your home used for business.
• Mileage and vehicle expenses: If you use a vehicle for business purposes, you can either deduct the actual expenses (e.g., gas, maintenance, and insurance) or use the IRS standard mileage rate. Be sure to track your mileage carefully throughout the year.

Depreciation: If you’ve purchased significant assets like equipment or office furniture, you can deduct a portion of the cost each year through depreciation. Make sure you’ve accounted for any eligible assets.

• Bad debt write-offs: If you’ve decided to write off any unpaid invoices as bad debt (from Step 5), don’t forget to deduct those amounts from your taxable income, which will reduce your tax liability.
• Tax credits: In addition to deductions, look for any tax credits you may qualify for. Credits like the Work Opportunity Tax Credit (WOTC)^[4]or research and development (R&D)^[5] credits can reduce the amount of taxes you owe directly.

Step 8: Plan for the new year

Now that your books are in order, it’s time to set yourself up for success in the new year. This step is all about building habits and systems that keep you from falling behind on your books again.

Here’s how to hit the ground running:

• Set a regular bookkeeping schedule: Make it a habit to review and update your financial records on a weekly or monthly basis. Dedicating regular time to your books will stop things from piling up and make those year-end tasks way less stressful.
• Use accounting software: If you’re not already using it, consider switching to accounting software like QuickBooks, Xero^[6], or FreshBooks^[7]. These tools can automate much of the process—like categorizing transactions, reconciling bank accounts, and generating reports—making your life a whole lot easier.
• Outsource if needed: If bookkeeping is eating up too much of your time or causing stress, it might be worth outsourcing to professionals. Cocountant can keep your records organized throughout the year, giving you peace of mind and freeing you up to focus on growing your business.
• Review your business goals: Use your year-end financial reports to reflect on the past year. What went well? Where did you struggle? Based on those insights, set new financial goals. Whether it’s improving cash flow, cutting unnecessary expenses, or preparing for growth, now is the time to make strategic decisions for the year ahead.
