As a subcontractor, managing your finances and keeping track of your business expenses is critical to your success. Unlike employees who have taxes withheld and are provided with regular paychecks, subcontractors are responsible for handling their own income, taxes, and business expenses. This means that good bookkeeping is not just an option — it's a necessity.

Without solid financial organization, subcontractors can quickly find themselves overwhelmed and at risk of missing important tax deadlines or underreporting income. But don’t worry; with the right strategies, bookkeeping for subcontractors can be manageable, efficient, and even straightforward. Here are essential bookkeeping tips for subcontractors to help you stay on top of your finances and ensure that your business runs smoothly.

1. Separate Personal and Business Finances

One of the first steps to effective bookkeeping is to separate your personal and business finances. Mixing the two can cause confusion and make it difficult to track income and expenses accurately, leading to potential issues when tax time rolls around.

To keep your financials organized, open a dedicated business checking account and apply for a business credit card. Use these accounts for all business-related transactions, including payments for materials, subcontractor services, and other business expenses.

Tip: If you’re using a credit card for business expenses, be sure to categorize purchases correctly. For example, expenses for supplies or vehicle-related costs should be recorded appropriately to ensure you’re claiming the right deductions.

2. Track All Income and Expenses

As a subcontractor, you'll likely work on multiple projects for various clients. It’s essential to keep track of each job’s income and expenses to maintain an accurate picture of your business’s financial health. This is especially important when preparing your tax return and determining your profitability.

You’ll need to track income from different sources and expenses such as:

• Materials: Supplies, tools, and other materials you purchase for the job.
• Labor Costs: Wages paid to other subcontractors or workers you hire.
• Vehicle Expenses: Gas, maintenance, and repairs for the vehicle(s) you use for work.
• Office Expenses: Phone, software subscriptions, office supplies, and home office expenses if applicable.
• Insurance: General liability insurance and any other business-related insurance premiums.

Tip: Use bookkeeping software or an accounting app to track your income and expenses easily. Tools like QuickBooks, Xero, or FreshBooks can help you stay organized, generate reports, and categorize transactions quickly.

3. Keep Detailed Records of All Transactions

Detailed record-keeping is critical, not just for tax purposes but also for tracking the success of your business. Keep receipts for every expense, including materials, supplies, and any services you pay for related to your work as a subcontractor. You should also document all payments you receive from clients, including any invoices you issue.

This documentation is essential in case of an audit and will also help you track where your money is going. It's easier to analyze your spending, improve cash flow, and assess your profitability when you maintain clear records.

Tip: Consider using digital tools to scan and store receipts for easy reference. Apps like Expensify or Receipt Bank can help you organize and track your receipts without the need to keep physical copies.

4. Stay On Top of Invoicing

Effective invoicing is key to maintaining a smooth cash flow. As a subcontractor, you’ll likely submit invoices after completing work for a client. Make sure your invoices are clear, professional, and detailed, including:

• Your business name and contact information
• The client’s name and contact details
• A breakdown of services provided
• The total amount due, payment terms, and the due date
• Any taxes applied (sales tax, for example, if applicable)

Be sure to send invoices promptly after completing work and follow up with clients if payments are delayed. Keeping accurate records of payments received and outstanding invoices will help you stay on top of your finances and ensure you’re paid on time.

Tip: Set up automated reminders for unpaid invoices to stay on top of collections without having to chase down clients manually.

5. Understand Your Tax Obligations

Subcontractors are classified as independent contractors, which means you are responsible for your own taxes, including self-employment taxes. The IRS requires you to pay both the employee and employer portions of Social Security and Medicare taxes, typically through quarterly estimated tax payments.

Keep in mind the following:

• Quarterly Estimated Taxes: As a subcontractor, you will need to make estimated tax payments four times a year to cover your federal income tax, state income tax (if applicable), and self-employment taxes.
• 1099 Forms: If you earn $600 or more from a client in a given year, they are required to issue you a 1099-NEC form, which reports your earnings to the IRS.
• Deductions: You can deduct a variety of business expenses, such as the cost of materials, vehicle use, and home office expenses. Make sure to track all eligible deductions to minimize your taxable income.

Tip: Work with a tax professional or use tax software to ensure you’re calculating your taxes correctly and taking advantage of all available deductions.

6. Keep an Eye on Cash Flow

Effective cash flow management is one of the most important aspects of running a subcontractor business. Even though you might be earning a good amount of money, poor cash flow management can leave you unable to pay bills or cover business expenses.

To improve cash flow, keep track of:

• Outstanding Invoices: Monitor which clients still owe you money and set up follow-up procedures for unpaid invoices.
• Expenses: Keep a close eye on your outgoing expenses, including materials and overhead costs.
• Tax Payments: Set aside money each quarter to ensure you have enough to cover estimated taxes.

Tip: Set aside a separate business savings account to cover tax obligations and emergencies, so you aren’t caught off guard when bills are due.

7. Consider Hiring a Bookkeeper or Using a Professional Service

If you find bookkeeping too time-consuming or complex, consider hiring a professional bookkeeper or accounting service. An experienced bookkeeper can help you manage day-to-day financial transactions, maintain accurate records, and prepare reports that give you insight into your business’s financial health. Additionally, an accountant or tax professional can help with tax preparation and offer advice on maximizing deductions.

Tip: Hiring a professional may feel like an additional expense, but it can save you time, reduce the likelihood of mistakes, and potentially save you money on taxes in the long run.

Conclusion

Bookkeeping is a crucial part of managing a successful subcontractor business. By staying organized, tracking your income and expenses, invoicing promptly, and understanding your tax obligations, you can ensure that your business is financially sound and positioned for growth.

Utilizing the right tools, staying on top of cash flow, and considering professional help will keep your financial house in order, allowing you to focus on what you do best: delivering excellent service to your clients. Whether you’re just starting out or have an established subcontracting business, effective bookkeeping will help you avoid pitfalls, maximize profits, and secure your financial future.
