"Now I'm working 50 hour weeks but only 35 are billable."
That's from a consultant on Reddit describing their reality after two years of growing a practice. The other 15 hours? Invoicing, email, scheduling, CRM updates, proposal formatting, chasing late payments, and managing a VA who was supposed to save time but created different work.
At $200/hour, those 15 non-billable hours cost $3,000 per week. $12,000 per month. $144,000 per year.
That's the admin tax. And it goes up every year your business grows.
Key Idea
Your admin tax is the difference between your total hours worked and the hours you can actually bill. As your practice grows, that gap widens unless you deliberately build operations around you.
Compounding Risk
If you grow revenue without building operations, you lock in a higher admin tax at every new level of your business. The longer you wait, the harder it is to unwind.
Quick Calculation
Take your hourly rate × non-billable hours per week × 4.3. That’s your monthly admin tax. If that number is more than 3× what you’d pay for proper operations support, you’re under-investing in leverage.
