Individual Tax Returns

|---|---|---|
| Simple 1040 (W-2 only) | $75–$175 | 30–60 min |
| 1040 with investments | $150–$300 | 1–2 hrs |
| Self-employed/1099 filers | $200–$400 | 2–3 hrs |
| Complex high-income returns | $400–$800+ | 3–6 hrs |

Tax season math: 40 clients × $300 average = $12,000 in 3 months — entirely on the side.

2. Freelance Bookkeeping
Year-round, recurring income from small business owners who need monthly bookkeeping but can’t afford a full-time bookkeeper.
| Business Size | Monthly Fee | Services Included |

3. Fractional CFO Consulting
High-growth startups and small businesses need CFO-level financial strategy but can’t afford a full-time CFO ($150,000–$300,000/year). Enter the fractional CFO.

| CPE requirements | CPA licensure requires continuing education — adds time cost |
| Tax season burnout | March–April can be brutal with both a day job and side clients |
| Client management time | Billing, follow-ups, and difficult clients take time |
Bottom Line
| Question | Answer |
|---|---|
| Fastest way to earn | Tax season prep clients |
| Highest recurring revenue | Fractional CFO or bookkeeping retainer clients |

Accountants who build a side practice are in an enviable financial position: they can serve 5–10 bookkeeping clients for $3,000–$6,000/month in recurring revenue while their full-time job handles fixed expenses. The accounting credentials you already hold are worth far more than you’re currently being paid for them.
