One of the most common questions business owners ask is:
“How much should I be setting aside for taxes?”
If you’ve ever felt unsure about that number, you’re not alone. Most service-based business owners were never shown a simple system — they’re just told to “save for taxes” and left guessing.
The good news? You don’t need a perfect number. You just need a consistent plan.
Here’s a simple timeline you can follow throughout the year to stay ahead of taxes and avoid the last-minute scramble so many business owners face.
January: Take Deep Breath
Honestly, January is most likely taken up preparing for taxes from your prior years work (if you’re doing your own bookkeeping).
Now take a deep breath, and bring your learnings from your recent tax prep to get ready for the upcoming year.
BUT, don’t take more than the month of January! The sooner you start, the easier!
February: Choose Your Starting Percentage
At the beginning of the year, set a baseline percentage to save from your profit. For many service-based businesses, 25–30% of net profit is a reliable starting point, but use last year as your guide.
This doesn’t have to be exact. It’s simply a starting place so you’re building the habit early instead of trying to catch up later.
One important reminder: taxes are based on profit, not total revenue.
If your business brings in $10,000 but expenses total $4,000, your tax estimate should be based on the $6,000 profit — not the full $10,000.
That distinction alone can prevent a lot of confusion (and over-saving or under-saving).
Monthly: Review Profit and Transfer Tax Savings
At the end of each month, review your Profit & Loss report and calculate your estimated tax to set-aside based on that month’s profit.
Then transfer that amount into a separate savings account labeled “Taxes.”
This simple routine keeps things manageable and predictable.
It also helps prevent one of the most common problems business owners face: unintentionally spending money that really should have been reserved for taxes. When everything sits in one account, it’s easy for tax funds to get used for supplies, payroll, or unexpected expenses — and suddenly tax season feels overwhelming.
Setting the money aside monthly removes that stress and gives you a clear picture of what you can safely use for operations and growth.
Quarterly: Prepare for Estimated Tax Payments
Throughout the year, many profitable business owners are required to make quarterly estimated tax payments. These deadlines can feel stressful if you haven’t been planning ahead.
But when you’ve been setting aside money monthly, those payments become much more manageable. Instead of scrambling to come up with a lump sum, the funds are already there waiting.
Quarterly is also a natural time to pause and ask:
- Is income higher or lower than expected?
- Do I need to adjust my savings percentage?
- Is my cash flow still comfortable?
Small adjustments throughout the year are far easier than trying to fix everything at once later.
Mid-Year Check-In: Adjust as Needed
By the middle of the year, you’ll have a clearer sense of how your business is performing. If revenue has increased or expenses have changed, it may make sense to slightly adjust the percentage you’re setting aside.
This is also a great time to review your numbers with your bookkeeper or CPA. A quick mid-year check-in can confirm that you’re on track and prevent an unpleasant surprise next tax season.
Planning ahead like this isn’t about being perfect — it’s about staying informed and making small, proactive adjustments instead of reacting at year-end.
Year-End: Review and Fine-Tune
As the year wraps up, compare your total profit with the taxes you’ve already set aside and paid. This gives you a clear picture of whether you’re on target or need to make a final adjustment before filing.
It also provides valuable insight for the coming year. If your percentage worked well, you can continue with confidence. If not, you now have real data to refine your plan instead of relying on guesswork.
When books are clean and updated regularly, this year-end review becomes a simple check-in instead of a stressful deep dive.
The Goal: Consistency Over Perfection
You don’t need the exact right percentage on day one. What matters most is creating a consistent system you can rely on.
Choose a starting percentage.
Set money aside monthly.
Review your numbers quarterly.
Adjust as your business grows.
When taxes are treated as an ongoing business expense instead of a once-a-year surprise, cash flow becomes more predictable and far less stressful.

Final Thought
Tax planning doesn’t have to be complicated. Most business owners simply need a clear routine that removes the guesswork and builds confidence over time.
If you’re unsure what percentage makes sense for your business, that’s completely normal. The right number depends on your profit margins, deductions, and growth plans — and it becomes much easier to determine when your books are clean and up to date.
Clear, tax-ready financials allow you to plan ahead, protect your cash flow, and make informed decisions throughout the year instead of reacting when deadlines arrive.
