Why 25% to 30% Is the Starting Point
As a self-employed coach, you owe two separate taxes on your profit: self-employment tax and federal income tax. Self-employment tax covers Social Security and Medicare and sits at 15.3% of your net earnings, reported on Schedule SE. On top of that, your net coaching profit gets added to your other income and taxed at your regular federal income tax rate, which for most solo coaches lands somewhere between 10% and 24%. Add state income tax if your state has one. Stack these together and 25% to 30% of net profit is a reasonable default. If your coaching income puts you in a higher bracket, or you live in a high-tax state, move that number up to 30% to 35%.
The key word is net profit, not gross revenue. If a client pays you $5,000 for a package but $600 went to Kajabi fees, $150 to Stripe processing, and $400 to a certification renewal, your taxable profit is closer to $3,850. Track those business expenses on Schedule C so you are not setting aside tax money on income you never actually kept.
Save From Every Payout, Not Just at Launch
Coaching income is lumpy. A launch might bring in $30,000 in one week, followed by two quiet months. The mistake many coaches make is treating that launch deposit as spendable cash, then scrambling when the tax bill shows up. Instead, move a fixed percentage into a separate savings account every time money hits your Stripe or PayPal balance, before you touch it for ads, a VA, or your own paycheck. Treating your tax savings like a bill that gets paid the same day you get paid removes the guesswork later.
If your income varies a lot month to month, consider adjusting your savings rate based on your running year-to-date profit rather than a flat percentage of each transaction. Early in the year, when you are not sure how the year will shake out, saving 30% is the safer buffer. You can always release extra savings back to yourself once you know your actual tax situation.
Quarterly Estimated Taxes
The IRS expects self-employed coaches to pay taxes throughout the year, not just in April. This happens through quarterly estimated tax payments using Form 1040-ES, generally due in mid-April, mid-June, mid-September, and mid-January. If you skip these and owe a large amount at filing time, the IRS can charge an underpayment penalty, even if you pay in full by the deadline.
To estimate each payment, look at your year-to-date net profit, apply your savings percentage, and pay roughly a quarter of your expected annual tax liability each period. Coaches with uneven launch income should recalculate after each big launch rather than paying the same flat amount every quarter, since a strong Q2 launch can significantly change what you owe.
Building Your Own Safety Margin
Because certification renewals, software subscriptions, and platform fees eat into your real profit, it is worth calculating your actual margin at least quarterly, not just guessing based on revenue. A coach who nets 60% of gross revenue needs a very different savings plan than one who nets 85%. Once you know your real profit margin and your marginal tax bracket, you can set a personalized savings percentage instead of relying on a generic rule of thumb, and adjust it as your income grows.
