Benefits: Clean separation, easy tracking, more professional

Method 2: Digital Receipt Management

Go paperless with receipt scanning:

1. Take photo of every receipt immediately
2. Use receipt scanning app
3. Categorize expense right away
4. Store digitally in cloud
5. Shred physical receipts after scanning (or keep for major purchases)

Method 3: Mileage Tracking

For vehicle expenses, track every business mile:

• Use mileage tracking app with GPS
• Log date, starting point, destination, purpose
• Calculate deduction using IRS standard rate (check current rate annually)
• Alternative: Track actual vehicle expenses (gas, maintenance, insurance)

Method 4: Expense Management Software

Use dedicated tools that:

• Connect to bank accounts
• Automatically categorize transactions
• Store receipt images
• Generate expense reports
• Integrate with accounting software

Organizing Expense Categories

• Rent or lease
• Repairs and maintenance
• Supplies

• Utilities
• Other expenses

What Documentation to Keep

The IRS requires proof of:

• Amount: How much you spent
• Date: When the expense occurred
• Business purpose: Why it was necessary
• Business relationship: Who you paid (for certain expenses)

Acceptable Documentation

• Receipts (paper or digital)
• Canceled checks
• Credit card statements
• Invoice copies
• Bank statements
• Electronic payment confirmations

How long to keep: Minimum 3 years, but 7 years is safer for major expenses

Special Situations

Home Office Deduction

If you work from home, you can deduct:

• Percentage of rent/mortgage
• Utilities
• Internet
• Repairs and maintenance

Requirement: Space must be used exclusively and regularly for business

Meals and Entertainment

Current rules (verify annually as they change):

• Business meals: 50% deductible
• Entertainment: Generally not deductible
• Client meals: 50% deductible
• Office snacks/meals: 50% deductible

Documentation needed: Who attended, business purpose, amount

Mixed-Use Expenses

For expenses that are partly personal, partly business:

• Calculate business use percentage
• Only deduct business portion
• Keep detailed records showing allocation method

Example: Phone bill that's 60% business use = deduct 60%

Monthly Expense Review Routine

Set aside time each month to:

1. Review all transactions
2. Verify categorization
3. Upload any missing receipts
4. Reconcile accounts
5. Note any anomalies or questions
6. Calculate profit/loss

Recommended time: First week of each month for previous month

Tax Time Preparation

When tax season arrives:

1. Generate expense reports by category
2. Verify totals against bank statements
3. Gather any additional documentation
4. Review for missed deductions
5. Share organized records with accountant
6. File and store records properly
