Quick Answer
Record retainers as income when received, not when earned. If you get a $5,000 retainer in December 2026, report it on your 2026 taxes even if the work happens in 2027. According to IRS Publication 334, cash-basis taxpayers (most freelancers) report income when actually received.

When to record retainer income
As a cash-basis taxpayer (which includes most freelancers), you must record retainer income when you actually receive it, not when you earn it. According to IRS Publication 334, cash received is taxable income in the year received, regardless of when the work is performed.
This means if you receive a $5,000 retainer on December 15, 2026, it's 2026 taxable income even if all the work happens in January 2027.
Example: $10,000 web design retainer
Let's say you're a web designer who receives a $10,000 retainer on November 1, 2026, for a project that will be completed in February 2027:
Correct approach:
Common mistake:
How to track retainers in your books
Method 1: Simple income tracking
```
Date: Nov 1, 2026
Income: $10,000 - Client retainer (ABC Corp website)
Category: Design income
Status: Received
```
Method 2: Liability tracking (advanced)
Some freelancers prefer tracking unearned revenue:
```
Received: $10,000 (Unearned revenue - liability)
As work progresses: Move portions to earned income
```
However, for tax purposes, the entire retainer is still 2026 income regardless of your internal tracking method.
Refundable vs. non-refundable deposits
*Even refundable deposits are generally income when received under cash-basis accounting
Quarterly tax planning with retainers
Retainers can create quarterly estimated tax challenges:
Example calculation:
If receiving a $15,000 retainer increases your annual income from $85,000 to $100,000:
What you should do
1. Record retainers as income immediately when received
2. Set aside taxes (25-35% depending on your bracket) from retainer payments
3. Track project progress separately from tax reporting
4. Use the freelance dashboard to categorize and monitor all advance payments
5. Make quarterly estimated payments that include retainer income
Key takeaway: Retainers are taxable income when received, not earned. Set aside 25-35% immediately for taxes and include in quarterly estimated payments.

Key Takeaway: Record retainers as income when received, not earned, and immediately set aside 25-35% for taxes to avoid quarterly payment shortfalls.
