What Can You Write Off? Understanding Business Expenses in QuickBooks

One of the most common questions business owners ask is, “Can I write this off?”

It’s an important question, but the answer isn’t simply about whether something was purchased for the business. Business owners need to understand why the expense was incurred, whether it is appropriate for the business, and what documentation supports it.

In Episode 43 of QuickBooks Mastery for Small Business Success, Erica Northrup and Lee Davis discuss what business owners need to know about deductions and how QuickBooks can help organize expenses before tax time.

The goal isn’t to find every possible write-off.

The goal is to accurately identify legitimate business expenses and keep the documentation needed to support them.

What Has to Be True for Something to Be Deductible?

A business expense generally needs to be ordinary and necessary for the business.

In practical terms, the expense should be helpful and appropriate for the business.

This doesn’t mean that every expense has to be inexpensive. It means there should be a legitimate business reason for the purchase.

An expense that is unusual or excessive for the nature of your business may require additional scrutiny.

And there’s an important misconception to clear up:

A Deduction Doesn’t Make Something Free

When you deduct a legitimate business expense, you are reducing the amount of income subject to tax.

You are not getting the entire purchase price back.

For example, spending $1,000 on a deductible business expense doesn’t mean the government gives you $1,000 back. The deduction reduces your taxable income according to the applicable tax rules.

That’s why business owners should focus on making smart business purchases—not buying things simply because they might be deductible.

Ask Four Questions About Every Expense

When you’re trying to determine whether a purchase is a legitimate business expense, start with four questions:

1. What Did We Buy?

Be specific.

Don’t simply record something as “miscellaneous.”

Knowing exactly what you purchased makes it easier to determine how it should be categorized and whether it is a business expense.

2. Why Did We Buy It?

What was the business purpose?

Why was the purchase necessary or helpful to the business?

The purpose behind the expense matters.

3. What Part of This Is Personal?

Some purchases may have both business and personal components.

Identify the personal portion rather than automatically treating the entire transaction as a business expense.

Mixed transactions should be split appropriately.

4. What Documentation Do I Have?

What supports the purchase?

That might include:

  • A receipt
  • A bill
  • An invoice
  • A mileage record
  • A business-purpose memo
  • Other supporting documentation

Good documentation helps tell the story of the transaction.

Your Chart of Accounts Matters at Tax Time

Your Chart of Accounts is more than a list of categories inside QuickBooks.

It helps organize your business income and expenses and gives you a clearer picture of what happened during the year.

When your expenses are categorized correctly, you can review your Profit and Loss before tax time and see where your money actually went.

Some of the expense categories business owners may need to review include:

  • Wages and overtime
  • Bank charges
  • Advertising
  • Dues and subscriptions
  • Legal expenses
  • Accounting and bookkeeping
  • Repairs and maintenance
  • Office expenses
  • Rent or lease
  • Utilities
  • Travel

The better organized these categories are, the easier it becomes to review your financial information and work with your tax professional.

Meals and Entertainment

Meals and entertainment are areas where business owners need to be particularly careful.

Entertainment expenses generally aren’t deductible under current federal tax rules, while qualifying business meals are generally subject to a 50% deduction limitation.

Meals also shouldn’t be lavish or extravagant under the applicable tax rules.

More importantly, don’t rely on your memory months later to explain a meal.

When recording a business meal, make a habit of documenting:

  • Who attended
  • What was discussed
  • The date
  • The amount
  • Whether entertainment was part of the transaction

The more information you record at the time of the expense, the easier it is to support the transaction later.

Don’t Forget Vehicle Mileage

Vehicle expenses can become complicated quickly, particularly when a vehicle is used for both business and personal purposes.

One of the most important habits is to track your mileage.

Don’t wait until tax time and try to reconstruct an entire year’s driving from memory.

Keep your mileage records current so you can distinguish business use from personal use and provide the documentation needed to support the deduction.

Equipment and Fixed Assets

Not every large purchase should immediately be treated as an expense.

Equipment and other long-term purchases may need to be recorded as fixed assets and depreciated over time, depending on the applicable tax and accounting rules.

A useful concept discussed in the episode is the $2,500 safe harbor threshold. Businesses that elect the applicable safe-harbor treatment may generally expense certain qualifying items below that threshold rather than capitalizing them.

However, the $2,500 figure isn’t a universal rule that automatically determines how every purchase should be recorded.

The key question is whether the purchase provides value beyond the current year and how it should be treated under the applicable tax rules.

When you’re unsure, flag the purchase and discuss it with your accountant.

Loans: Don’t Expense the Entire Payment

Loan payments are another common area of confusion.

A loan payment generally contains two different components:

  • Principal
  • Interest

Interest is an expense.

Principal, however, reduces the amount you owe on the loan. It isn’t simply another business expense.

If you record the entire loan payment as an expense, you can distort your Profit and Loss and your Balance Sheet.

Your bookkeeping should separate these components so your financial statements accurately reflect what happened.

Make Documentation Part of the Process

One of the easiest ways to make tax preparation less stressful is to document expenses when you enter them.

Don’t wait until the end of the year.

When you enter a bill, attach the documentation right away.

At the same time, add a memo explaining the business purpose when appropriate.

If a transaction includes both business and personal expenses, split it when you record it.

These small habits can make a significant difference when you eventually need to review your books.

Do a Quick Expense Review Today

You don’t have to wait until tax season to start reviewing your deductions.

Open QuickBooks and take a look at your numbers now.

1. Run a Year-to-Date Profit and Loss

Run your Profit and Loss from January 1 through the current date.

Then compare it with the same period from last year.

Look for significant changes.

2. Review Your Major Expense Groups

Scan categories such as:

  • Advertising
  • Automobiles
  • Meals
  • Insurance
  • Fees
  • Repairs
  • Utilities
  • Travel
  • Rent
  • Supplies
  • Subscriptions
  • Licenses
  • Depreciation
  • Interest

You’re looking for expenses that are unusually high, unusually low, or significantly different from the prior year.

3. Open the Details Behind the Five Largest or Most Unusual Expenses

Don’t stop at the total on the Profit and Loss.

Open the transactions behind your five largest or most unusual expenses.

Ask:

What was this? Why did we purchase it? Is it categorized correctly? Do we have documentation?

4. Review Uncategorized and “Ask My Accountant” Accounts

Look for transactions that haven’t been properly categorized.

These accounts can contain important information that needs to be resolved before your financial statements are considered reliable.

Don’t allow transactions to sit there indefinitely.

5. Find Equipment and Vehicle Purchases

Review equipment and vehicle purchases.

Confirm that supporting documentation is attached and flag anything that may need to be treated as a fixed asset.

6. Review Loan Payments

Find your loan payments and confirm that principal and interest are being separated appropriately.

If the entire payment is being recorded as an expense, it’s worth investigating.

7. Check Three Meals, Travel, or Vehicle Expenses

Choose three transactions from meals, travel, or vehicle expenses.

Check whether each one has the appropriate documentation and business-purpose information.

If those three transactions aren’t well documented, that’s a good indication that you may need to improve your process for the rest of the year.

Good Bookkeeping Makes Tax Time Easier

Understanding deductions isn’t just about finding expenses to write off.

It’s about having accurate books that tell the story of your business.

When your Chart of Accounts is organized, your expenses are categorized correctly, documentation is attached, mixed transactions are separated, and unusual purchases are identified, you and your accountant have much better information to work with.

QuickBooks can help you organize that information, but it still requires good habits.

Enter the expense correctly. Document it immediately. Categorize it appropriately. Ask questions when something doesn’t make sense.

The Bottom Line

A tax deduction is a business expense that reduces taxable income—it isn’t free money.

Before treating an expense as deductible, ask four questions:

What did we buy? Why did we buy it? What part is personal? What documentation do we have?

Then use QuickBooks to organize the information and review your financial statements regularly.

The goal isn’t simply to maximize write-offs.

The goal is to have accurate, well-documented business expenses that you can confidently support.

Good bookkeeping throughout the year makes that process much easier—and can help you and your tax professional understand the complete financial story of your business.


Is Your QuickBooks File Ready for Tax Season?

Tax season can be stressful enough without discovering that your QuickBooks file needs significant cleanup.

Before handing your financial information to a tax professional, you should have a reasonable level of confidence that your books are accurate, organized, and ready for review.

In Episode 42 of QuickBooks Mastery for Small Business Success, Erica Northrup and Lee Davis discuss what it really means for your QuickBooks file to be ready for tax season.

Being ready doesn’t mean your CPA needs to take over your QuickBooks file.

Your tax professional should be able to review the financial information, identify potential issues, and use the completed bookkeeping to help optimize your tax situation.

The bookkeeping is your responsibility. The tax strategy is your tax professional’s responsibility.

What Does “Ready” Actually Mean?

When someone says their QuickBooks file is ready for tax season, what should that mean?

At a minimum, you should be able to answer some important questions about your books.

1. Are Your Bank Accounts Reconciled?

Start with your bank accounts and credit cards.

Have they been reconciled through the most recent statement?

If QuickBooks says you have one amount of money and your bank statement says something different, you need to investigate the difference.

Reconciliation helps identify missing, duplicate, or incorrectly recorded transactions.

2. Are There Uncategorized Transactions?

Look for transactions sitting in Uncategorized accounts or other areas waiting for clarification.

These transactions haven’t been properly assigned to the correct account.

Don’t leave them for your tax professional to figure out at the last minute.

Review them now and determine what they actually represent.

3. Are Your Loans Recorded Properly?

Loan payments need special attention.

A loan payment generally includes both principal and interest.

Interest is an expense. Principal reduces the loan balance.

If the entire loan payment is recorded as an expense, your Profit and Loss can be distorted.

Make sure your loan accounts are set up properly and that payments are being recorded correctly.

4. What’s the Status of Accounts Payable?

Look at your Accounts Payable.

Do you have bills that are still outstanding?

Are those bills actually owed?

Do you have a stack of unpaid bills that haven’t been entered into QuickBooks?

Your Accounts Payable should represent what the business genuinely owes.

5. Does Accounts Receivable Reflect What You’re Owed?

Accounts Receivable should represent money your customers owe you.

Review your outstanding invoices.

Are they legitimate?

Are they still collectible?

Are there old balances that should be investigated?

If your Accounts Receivable is inflated with old or incorrect balances, your financial statements aren’t telling the full story.

6. Are Major Assets Recorded Properly?

Review major purchases such as equipment, vehicles, or other significant assets.

Make sure they haven’t simply been recorded as ordinary expenses when they should be treated differently.

Major assets can affect both your Balance Sheet and your tax return, so they deserve attention before tax season.

7. Do Your Balance Sheet and Profit & Loss Make Sense?

Look at both major financial statements.

Your Profit and Loss should reasonably reflect the income and expenses of your business.

Your Balance Sheet should reasonably reflect what the business owns, what it owes, and its equity.

Look for negative balances that shouldn’t exist.

If something looks unusual, investigate it.

Your tax professional needs financial information they can rely on.

8. Review Undeposited Funds

Don’t forget Undeposited Funds.

If money has been sitting there for an unusually long time, determine why.

It may indicate that payments were entered but not properly deposited or matched.

A large or old Undeposited Funds balance can be a sign that part of the sales and payment process needs to be reviewed.

Red Flags to Look For

As you prepare your books, certain issues should immediately get your attention.

Loan Accounts Classified as Expenses

If loan accounts or entire loan payments are being classified as expenses instead of separating principal and interest, your Profit and Loss may be overstated.

Investigate how those transactions have been recorded.

Old Accounts Receivable

Outstanding Accounts Receivable can make your financial position look better than it really is if the balances aren’t actually collectible.

Review old invoices and determine whether the balances are legitimate.

A Stack of Bills

If you have bills sitting on your desk that haven’t been entered into QuickBooks, your books may not reflect your actual obligations.

Enter your bills and make sure Accounts Payable accurately reflects what you owe.

Uncategorized Expenses

Uncategorized transactions are a warning that your books aren’t finished.

Go through them and determine what each transaction represents.

Old Bank Feed Transactions

Don’t let old transactions sit indefinitely in the bank feed.

They may be duplicates, transactions that were entered incorrectly, or items that haven’t been properly categorized.

Investigate them.

Outstanding Payroll Liabilities

Payroll liabilities that are old or unexplained need attention.

Make sure payroll taxes and other payroll-related liabilities have been recorded and paid correctly.

Unreconciled Loans

If you have loans, make sure the loan balances and payments are being reconciled and reviewed.

The loan balance in QuickBooks should make sense compared with your actual loan statements.

Why Find These Problems Now?

You might wonder why you should spend time cleaning up your QuickBooks file before your tax professional even looks at it.

The answer is simple:

You have deadlines.

Businesses have reporting requirements for items such as W-2s and 1099s, and the information supporting those filings needs to be accurate and up to date.

The longer you wait to identify problems, the more difficult it can be to resolve them before deadlines arrive.

Finding an issue in October gives you time to investigate.

Finding it right before a filing deadline creates unnecessary pressure.

Your Tax Professional Shouldn’t Be Your Bookkeeper

One of the most important distinctions discussed in this episode is the difference between bookkeeping and tax preparation.

Your tax professional’s job is to help you optimize your taxes and prepare your tax return based on accurate financial information.

Your bookkeeping is the foundation that provides that information.

You don’t want your CPA or tax preparer spending valuable time trying to reconstruct your books, categorize transactions, reconcile accounts, or figure out why your Balance Sheet doesn’t make sense.

Instead, your tax professional should be able to review the completed financial information and focus on the tax questions that require their expertise.

Think of it as a flyover.

They want to look at your books, identify potential red flags, and determine whether the financial information is ready for tax preparation.

What Does Your Tax Professional Want?

Your tax professional will typically provide a list of documents and information they need.

But before you hand everything over, make sure your QuickBooks file supports those documents.

They want to see clean books.

They want to understand significant changes.

And they want to investigate red flags before preparing your return.

If there are major problems throughout the QuickBooks file, the tax professional may have to spend additional time addressing those issues before they can move forward.

That’s time and money that could often be saved by getting your bookkeeping in order first.

Give Yourself 15 Minutes

You don’t need an entire afternoon to begin.

If you only have 15 minutes, start here:

1. Check the Bank Feed

Look for old transactions that are still sitting there.

Make a note of anything unusual or unresolved.

2. Look at Your Profit and Loss

Does it make sense?

Does the income look reasonable?

Are there expenses that seem unusually high or low?

Are there categories you don’t recognize?

3. Check Your Bank Reconciliations

Are your accounts reconciled through the most recent statement?

If not, make a note of which accounts need attention.

Make a List and Start Investigating

You don’t have to solve every problem in one sitting.

Start by making a list.

Maybe you find:

  • Three old bank-feed transactions
  • Two unreconciled bank accounts
  • An unexplained loan balance
  • Several uncategorized expenses
  • Old Accounts Receivable
  • Outstanding payroll liabilities

That’s okay.

Now you know what needs attention.

You have time to investigate.

Work through the list one item at a time.

Get Ahead of Tax Season

Being ready for tax season isn’t about making your QuickBooks file look perfect.

It’s about making sure the major pieces of your financial information are accurate enough for you and your tax professional to rely on them.

Reconcile your accounts.

Clean up old transactions.

Review Accounts Receivable and Accounts Payable.

Check your loans.

Review payroll liabilities.

Look at your Balance Sheet and Profit and Loss.

Review Undeposited Funds.

Investigate anything that doesn’t make sense.

Then your tax professional can do what you hired them to do—help you make the most of your tax situation using financial information they can trust.

The Bottom Line

Tax season shouldn’t be the first time you discover problems in your QuickBooks file.

The earlier you identify issues, the more time you have to understand them and correct them.

Your bookkeeping provides the foundation.

Your tax professional uses that foundation to prepare and optimize your taxes.

So before tax season arrives, ask yourself:

Are my books accurate enough that I trust the numbers?

If the answer is no—or you’re not sure—don’t wait until your tax deadline is approaching.

Start with 15 minutes.

Find the red flags.

Make a list.

And start getting your QuickBooks file ready.


Using QuickBooks Payments, the Bank Feed, and Time Tracking Effectively

In Episode 29 of QuickBooks Mastery for Small Business Success, Lee Davis and Erica Northrup discuss three features that can improve efficiency for business owners when used correctly: QuickBooks Payments, the Bank Feed, and Time Tracking.

Each of these tools is designed to simplify everyday business operations. However, like any feature in QuickBooks, success depends on understanding how they work and using them properly.

Quickbooks Mastery for Small Business Success

QuickBooks Payments: Making It Easier to Get Paid

One of the biggest advantages of QuickBooks Payments is convenience.

Instead of relying on paper invoices and mailed checks, businesses can email invoices that include a secure payment option. Customers can simply click a button to pay online, helping businesses receive payments faster and improve cash flow.

While many companies use QuickBooks Payments, others may prefer contractor payment systems or ACH transfers depending on their business model and customer preferences.

The key is choosing the payment solution that best fits both your business and your clients.

Setting Up QuickBooks Payments

Before accepting payments through QuickBooks, there are several setup steps to complete.

These include:

  • Verifying your bank account
  • Completing required business verification documents
  • Meeting QuickBooks’ payment processing requirements

Taking the time to complete the setup correctly helps ensure payments are processed smoothly.

Protecting Customer Payment Information

Erica and Lee also stress the importance of payment security.

Storing customer credit card information can expose a business to unnecessary risk and liability.

Using secure payment processing tools helps protect both your business and your customers while reducing the responsibility of handling sensitive financial information yourself.

Is QuickBooks Payments Right for Every Business?

Not necessarily.

Before enabling QuickBooks Payments, consider several questions:

  • How do your customers prefer to pay?
  • Will online payments improve customer convenience?
  • Are you comfortable with the payment processing fees?

For businesses that regularly process large-dollar transactions, those fees can add up quickly.

Evaluating your customer base and pricing structure can help determine whether QuickBooks Payments is the right solution.

Sending Invoices Is Simple

Once an invoice is created in QuickBooks, it can be emailed directly to the customer.

When QuickBooks Payments is enabled, the invoice includes a built-in payment option, allowing customers to pay immediately.

Without integrated payments, businesses often rely on mailed checks or other manual payment methods, which can slow down collections.

Avoid a Common Payment Mistake

One important reminder from Erica and Lee is to use the Receive Payment function correctly.

If a customer has already paid an invoice, record the payment using Receive Payment rather than creating a new charge.

Failing to do so could accidentally charge the customer a second time, creating unnecessary confusion and frustration.

Getting Started with the Bank Feed

The QuickBooks Bank Feed is another feature that can save time by importing transactions directly from your financial institutions.

However, Lee recommends waiting until you’ve been using QuickBooks for several months before activating the Bank Feed.

Why?

Learning to enter transactions manually first helps you understand:

  • How accounts are categorized
  • Which forms should be used
  • How transactions flow through QuickBooks

Building this foundation makes it much easier to recognize and correct mistakes later.

Match Instead of Add

Once the Bank Feed is active, one best practice stands out:

Match transactions whenever possible instead of simply adding them.

Matching connects downloaded bank activity to transactions you’ve already entered, helping prevent duplicate entries and improving the accuracy of your financial records.

Accounts That Can Connect Through the Bank Feed

The Bank Feed can connect to several types of financial accounts, including:

  • Checking accounts
  • Credit cards
  • Loans

Connecting these accounts allows QuickBooks to import transactions automatically, reducing manual data entry.

Choosing the Right Bank

Not every financial institution integrates with QuickBooks in the same way.

Before choosing a bank, consider:

  • Whether it has a strong QuickBooks integration
  • Whether connection fees apply
  • How reliably transactions synchronize

A well-supported financial institution can make bookkeeping much smoother.

What to Do If the Bank Feed Stops Working

Occasionally, bank connections experience interruptions.

If that happens, Erica and Lee recommend several troubleshooting steps:

  • Use Google Chrome, as QuickBooks performs best in that browser.
  • Click the Update button to refresh the connection.
  • Contact QuickBooks Support to determine whether there is an active connection issue between QuickBooks and your financial institution.

Many connection issues are temporary and can be resolved with a simple update.

Why Time Tracking Matters

The final topic in this episode is Time Tracking.

For service-based businesses, tracking employee or owner time provides valuable information for billing, payroll, and profitability.

Within QuickBooks, users can record:

  • Employee or contractor
  • Customer
  • Service provided
  • Hours worked
  • Date
  • Notes

Maintaining complete time records helps improve invoicing accuracy and provides better insight into labor costs.

Track Time Every Day

Lee recommends entering time daily rather than trying to remember hours at the end of the week.

Daily time tracking helps:

  • Improve billing accuracy
  • Reduce forgotten hours
  • Keep payroll records organized
  • Provide more reliable job costing information

Consistent habits make reporting more accurate and reduce administrative work later.

Final Thoughts

QuickBooks offers powerful tools to help businesses collect payments, automate transaction imports, and track employee time. But these features are most effective when they’re implemented thoughtfully and used consistently.

By understanding how QuickBooks Payments, the Bank Feed, and Time Tracking work together, business owners can streamline operations, improve cash flow, and maintain more accurate financial records.

As Lee Davis and Erica Northrup emphasize throughout QuickBooks Mastery for Small Business Success, technology is only as effective as the processes behind it. Taking the time to learn these tools today can save countless hours—and costly mistakes—in the future.
