Crypto tax clients are complex—they hold assets across multiple chains, execute dozens of trades yearly, and often underestimate their filing obligations. A retainer agreement locks in predictable revenue while giving clients peace of mind that their tax situation stays on top of your priority list. Here's how to structure retainers that work for both sides.
Why Retainers Beat Hourly Billing for Crypto Tax Work
Hourly billing creates misaligned incentives in crypto tax accounting. A client with 200 Ethereum transactions, three DeFi positions, and a staking income stream will rack up 15+ billable hours—potentially costing them $3,000–$6,000 depending on your rate. They'll hesitate to ask questions, and you'll feel pressure to rush through documentation.
Retainers flip this dynamic. The client knows their cost upfront (typically $500–$2,500/month for active traders, or $2,000–$5,000/month for high-net-worth clients with complex positions). You know your baseline revenue and can allocate your time accordingly.
Define What's Included in Your Crypto Tax Retainer
Vague retainer terms breed disputes. Be specific about what the client gets each month.
A good baseline retainer package includes:
- Transaction reconciliation: Importing and organizing trades from exchanges (Coinbase, Kraken, Uniswap, etc.) into accounting software
- Quarterly check-ins: 45-minute calls to review positions, discuss new tax strategies, and flag upcoming wash sale or staking income issues
- Tax planning for the current year: Ongoing advice on harvest losses, rebalancing, and timing decisions to minimize tax liability
- Preliminary year-end filing: Initial tax return preparation (1040 + Schedule D + Form 8949)
- Email support: Reasonable turnaround (48 hours) for quick questions about specific transactions
- Updates on regulatory changes: Monthly email summary of new IRS guidance or state-level crypto tax rules
Not included: Audit representation, amended returns for prior years, complex entity structuring, or forensic analysis of inherited crypto positions (these are add-ons billed separately).
Tiered Retainer Structure for Different Client Profiles
One-size-fits-all retainers leave money on the table. Create tiers tied to actual effort and complexity.
Starter Tier ($500–$800/month) For hobbyists and small traders (under $50,000 in annual volume). Limited to quarterly check-ins, basic reconciliation of 50–100 transactions, and email support only. No proactive tax planning.
Standard Tier ($1,200–$1,800/month) For active traders and small business owners (traders with $50,000–$500,000 in volume). Monthly reconciliation, bi-monthly planning calls, full tax return prep, and email/Slack support.
Premium Tier ($2,500–$4,500/month) For high-net-worth clients or those with multiple income streams (staking, yield farming, NFT sales, mining). Includes weekly check-ins, daily support, real-time transaction monitoring, and proactive tax strategy adjustments. This tier often justifies itself when a single harvest decision saves a client $10,000+ in taxes.
Set Clear Boundaries and Renewal Terms
Retainer agreements should specify contract length and expectations for both parties.
- Commitment period: 6 or 12 months. Crypto tax is seasonal (most returns file April–October), so shorter retainers leave you chasing renewals constantly.
- Notice period: 30 days for termination, effective the end of the month.
- Out-of-scope work: Define what triggers additional fees (e.g., more than 500 transactions/quarter, entity formation, audit defense).
- Annual adjustment clause: Built-in 5–10% increases on renewal to offset inflation and scope creep.
- Hard cap on transactions: Specify that if a client exceeds agreed-upon transaction volume, overage fees of $50–$100 per 50 transactions apply.
How to Sell Retainers to Prospects
Most crypto clients come to you after scrambling with their taxes. Position retainers as risk management, not cost.
When pitching: "If you filed taxes last year without a tax advisor, you likely missed $5,000–$15,000 in deductions. A retainer costs $1,500/month but saves that back in the first year through proper loss harvesting alone. Plus, you sleep better knowing you're compliant."

Frequently Asked Questions
Q: Can I include prior-year amended returns in a retainer? Generally no—amended returns are reactive, complex work best billed separately at a flat rate ($800–$2,000 per amended return). Retainers cover current-year planning and compliance only.
Q: What if a client's trading activity explodes mid-year? Have a conversation by month 3 or 4. Renegotiate the retainer tier upward or trigger your overage clause. Growth is good; losing margin on a retainer isn't.
Q: Should I offer retainers during off-season (June–December)? Yes, but market them differently. Pitch a "planning retainer" at 40–50% of your annual rate to keep clients engaged year-round and lock in their return prep come January.
