Running a small business in San Diego is both rewarding and demanding. Between managing employees, customer service, and operations, taxes often take a back seat — until it’s crunch time. At Lily Tax, we’ve helped hundreds of local businesses find deductions they never knew they were missing.
Here’s how to approach your deductions with confidence and strategy.
1. Know What Counts — And What Doesn’t
Many owners ask, “Can I deduct this?” If the expense is ordinary and necessary for your business, there’s a strong chance it qualifies. Examples we regularly see include:
- Software subscriptions (QuickBooks, Canva, etc.)
- Business use of your home
- Marketing and advertising
- Continuing education
- Mileage and vehicle use
San Diego example: We worked with a local event planner in La Jolla who saved over $2,000 in one year just by tracking travel and training expenses — something they’d overlooked for years.
2. Home Office: Still One of the Most Underused Deductions
If you’re using a portion of your San Diego home exclusively for business, you may qualify for the home office deduction. That includes a portion of utilities, internet, and rent or mortgage interest.
Many clients think this will raise a red flag — but when documented properly, it’s completely legitimate.
3. Meals and Entertainment: Know the 50% Rule
Yes, meals with clients are partially deductible — 50%, to be exact. But it has to be business-related and properly documented (who, what, and why).
Our team advises San Diego realtors and consultants to snap a photo of the receipt, jot down the purpose in their phone, and move on. It doesn’t need to be complicated.
4. Don’t Wait Until Tax Season
A common pattern we see? Business owners scrambling in March to tally expenses. The result: missed deductions and extra stress.
We recommend monthly bookkeeping or even quarterly check-ins, especially for San Diego businesses with seasonal trends like hospitality, surf schools, and independent contractors.
