Mid-Year Check-In: Why July Is the Best Time to Review Your Numbers (And How Much You Should Actually Be Setting Aside for Taxes in 2026)

Mid-Year Check-In 2026

Six months into 2026, most small business owners have a decent read on how the year is going. Revenue is either ahead of plan or behind it. Payroll is running. The busy season either happened or is still coming. What most owners have not done is stop and ask the one question that determines whether next March/April feels like a formality or a crisis: how much of what came in this year actually belongs to the IRS and the state? This is why a Mid-Year Check-In is smart!

July is the right month to ask it. The spring filing rush is over, the extension deadline is still a couple months away, and there is enough real income and expense data on the books to make an accurate projection instead of a guess. Wait until December and the options for fixing a problem shrink fast. Ask now and there is still time to adjust withholding, make an estimated payment, or change an entity structure before it costs anything extra.

This piece covers both halves of that mid-year conversation: why July is the moment to look, and the number every business owner actually wants, how much to set aside for taxes.

Why a Mid-Year Review Matters More in 2026

Two things make this July different from a routine check-in.

First, the One Big Beautiful Bill Act (OBBBA) reshaped a long list of business provisions for 2026, from the small business deduction to bonus depreciation to research expense rules. A plan built on 2025 assumptions may already be out of date.

Second, six months of actual bookkeeping data is simply more reliable than a projection made in January. A business that has real numbers from January through June can extrapolate the rest of the year with far more confidence than one that relies solely on last year’s tax return.

What a mid-year review should actually cover:

• Year-to-date profit compared to the same period last year

• Whether estimated tax payments made so far are tracking to actual income

• Entity structure, specifically whether an S-corp election still makes sense at current income levels

• Retirement plan contributions that still have time to be adjusted before year-end

• Equipment purchases planned for the second half of the year, and whether 100% bonus depreciation changes the timing decision

Plan a Mid-Year Financial Review with your CPA before the numbers get stale again.

What Taxes Do Small Businesses Actually Pay?

Before setting aside a dollar amount, it helps to know exactly which taxes that dollar is covering. For most small business owners, there are three layers.

1. Federal Income Tax

This is the tax on business profit itself, whether the business is a sole proprietorship, partnership, S-corp, or C-corp passing income through to the owner’s personal return. For 2026, federal income tax brackets run from 10% to 37%, with the standard deduction rising to $16,100 for single filers and $32,200 for married couples filing jointly, according to IRS Revenue Procedure 2025-32. The top 37% rate does not apply until taxable income exceeds $640,600 for single filers or $768,700 for married couples filing jointly, so most small business owners land somewhere in the 22% to 32% range on their business income.

Most pass-through business owners also qualify for the Section 199A Qualified Business Income deduction, a 20% deduction on qualifying business income that the OBBBA made permanent.

2. Self-Employment Tax

This is the one that catches new business owners off guard. Sole proprietors, single-member LLC owners, and partners pay self-employment tax at a combined rate of 15.3%, covering 12.4% for Social Security and 2.9% for Medicare, according to the IRS. The Social Security portion applies only to the first $184,500 of net self-employment income for 2026. Income above that threshold is subject only to the 2.9% Medicare portion, and an additional 0.9% Medicare surtax applies once combined income exceeds $200,000 for single filers or $250,000 for married couples filing jointly.

A business owner who elects S-corp status only pays this tax on their reasonable salary, not on the full profit distributed to them, which is one of the most common reasons growing businesses revisit entity structure.

3. State Income Tax

If you are a Georgia resident, Georgia has been phasing down to a flat personal income tax rate since 2022. For 2026, that rate is 4.99%, applied to all taxable income, with a standard deduction of $15,000 for single filers and $30,000 for married couples filing jointly, according to the Georgia Department of Revenue. Unlike many states, Georgia has no city or county income tax layered on top, which simplifies the math for business owners operating across the metro Atlanta area.

How Much Should a Small Business Set Aside for Taxes in 2026?

Here is the number most owners are actually looking for. There is no single percentage that fits every business, because it depends on entity type, profit margin, and household income, but the following ranges are a reliable starting point based on current 2026 rates.

Business Type	Recommended Set-Aside	Why
Sole proprietor / single-member LLC	25% to 30% of net profit	Covers 15.3% self-employment tax plus federal and state income tax on the remainder
Partnership / multi-member LLC	25% to 30% of each partner’s distributive share	Same combined tax exposure, applied per partner
S-corp owner (reasonable salary already withheld)	20% to 25% of K-1 distributive share	Payroll tax is already covered through W-2 withholding on salary; the remainder only owes income tax
Higher-income owners (combined household income above $250,000)	30% to 35% or more	Additional Medicare tax, higher marginal brackets, and possible Net Investment Income Tax exposure push the effective rate up

These ranges assume a business with a healthy profit margin and no unusual deductions or credits. A business with significant equipment purchases, home office deductions, or retirement plan contributions may need less. A business with a side hustle stacked on top of a W-2 job, or one nearing the Social Security wage base, may need to recalculate mid-year rather than relying on a flat percentage all year.

The practical version: every time a payment clears for work performed, move 25% to 30% of that deposit into a separate savings account before touching the rest. Businesses that do this consistently rarely get surprised in April. Businesses that treat the bank balance as the true profit number almost always do.

The Safe Harbor Rule: How to Avoid an Underpayment Penalty

Setting money aside is only half the job. The IRS also expects that money to be paid in during the year, not all at once in April, through quarterly estimated tax payments. The IRS safe harbor rule protects against an underpayment penalty as long as a business owner pays in, over the course of the year, whichever is smaller:

• 90% of the current year’s total tax, or
• 100% of the prior year’s total tax (110% if prior-year adjusted gross income was above $150,000, or $75,000 for married filing separately)

For 2026, the quarterly due dates are April 15, June 15, September 15, and January 15, 2027. Missing a quarter does not just mean a bigger bill later. It can mean interest charged on that specific quarter’s shortfall, calculated at the federal short-term rate plus three percentage points, even if the full year’s tax is eventually paid in full.

Case Study: Catching a Six-Figure Swing Before It Became a Problem

The following is an illustrative example based on a common pattern we see with growing service businesses, not an identification of any specific client.

A Woodstock landscaping company had a strong first half of 2026, with revenue up nearly 40% over the same period the year before, largely from three new commercial contracts. The owner had continued making quarterly estimated payments based on the prior year’s numbers, which had already been a solid year.

A mid-year review in July caught the gap. Based on six months of actual bookkeeping, the business was on pace to owe roughly $28,000 more in combined federal, self-employment, and Georgia tax than the estimated payments already made would cover. Because the gap was identified in July rather than discovered in April, there was still time to increase the September and January estimated payments, evaluate an S-corp election for the following year to reduce self-employment tax exposure on future growth, and time a planned equipment purchase to use 100% bonus depreciation before year-end. The result was a manageable, planned adjustment instead of a surprise bill with penalties attached.

This is the entire argument for a mid-year check-in. The tax bill does not change based on when you look at it. Only your ability to do something about it does.

Frequently Asked Questions

What taxes does a small business owner’s actually pay? Three main layers: federal income tax on business profit (10% to 37% depending on income), self-employment tax of 15.3% for sole proprietors and partners, and state taxes. For Georgia business owner’s there is a flat state income tax of 4.99% for 2026. S-corp owners pay payroll tax on salary instead of self-employment tax, and everyone pays Georgia’s flat rate on top of federal tax.

What happens if I don’t pay enough estimated tax during the year? The IRS can assess an underpayment penalty, calculated as interest on the shortfall for each quarter it went unpaid. The penalty can be avoided entirely by meeting the safe harbor rule: paying at least 90% of the current year’s tax or 100% of the prior year’s tax (110% for higher earners) through withholding and estimated payments spread across the year.

Is July too late to make changes for my 2026 tax bill? No. July is actually the ideal window. There is enough real income data from the first half of the year to project accurately, and there is still time before year-end to adjust estimated payments, time equipment purchases, evaluate an entity structure change, or increase retirement plan contributions. Waiting until the fourth quarter narrows those options considerably.

How Pantana CPA Helps You Avoid the April Surprise

A mid-year tax projection is the single most effective tool for making sure April never shows up with a number you weren’t expecting.

From there, we walk through where you stand against the safe harbor thresholds, whether your entity structure still fits your current income, and whether any planned purchases, hires, or retirement contributions should be timed differently before December 31. The goal is simple: by the time your projection is done, you know the number, you know the plan to cover it, and there is nothing left to guess about between now and tax season.
