Quarterly Estimated Tax Payment Schedule for LLCs

LLC owners—especially single-member and S Corp—may need to make estimated tax payments. Here’s the 2025 schedule:

Avoid IRS penalties by planning ahead. Our Bookkeeping Services help track income and generate accurate quarterly estimates.

Real-World Examples of Filing Deadlines

✔️ Jane – Single-Member LLC in Texas
Jane sells handmade products online and reports $90K revenue in 2024. She must file Schedule C with her personal Form 1040 by April 15, 2025. Since she didn’t pay estimated taxes in 2024, she faces penalties unless she pays the full tax bill by the due date. If you’re in a similar position, our Tax Management and Bookkeeping services ensure accurate planning.

✔️ Ravi & Kim – Multi-Member LLC in California
As co-owners of a marketing agency, Ravi and Kim must file Form 1065 by March 17, 2025. They’ll also need to distribute Schedule K-1s to report each partner’s income on their personal returns due April 15. Our Tax Preparation & Filing and Financial Reporting help streamline this entire process.

What Happens If You Miss a Deadline?

Missing a filing or payment deadline can lead to the following penalties:

Example: If your LLC owes $10,000 and you file three months late without payment, your penalty could reach $1,500+ in combined late filing and payment fees. Avoid this risk by Getting our services, which includes tax, payroll, and bookkeeping in one place.

Can You File for an Extension?

Yes, but remember: an extension gives you more time to file — not more time to pay.

We can file these extensions on your behalf via our Tax Preparation & Filing services, helping you use that extra time wisely to reconcile reports and organize records.

IRS Mileage Rates 2025 Explained: Maximize Your Tax Deduction with Confidence

by stiusallc | Jun 30, 2025 | Blog

For 2025, the IRS has updated the standard mileage rate for business use of a personal vehicle to 70 cents per mile — up from 67 cents in 2024. This rate applies to self-employed professionals, freelancers, and small business owners who use their personal car for work-related travel.

Here’s a quick breakdown:

If you drive 5,000 miles for business in 2025, your total deduction would be $3,500 using the standard mileage method.

💡 Need help calculating your business mileage deduction? Our services can do that for you — with full IRS compliance.

Who Can Claim the Mileage Deduction in 2025?

Mileage deductions aren’t for everyone — and the IRS has specific rules about who qualifies. Here’s a simple rule of thumb:

Eligible:

• Sole proprietors
• Independent contractors
• Freelancers
• Single-member LLCs

Not eligible:

• W-2 employees (unless your employer has a formal reimbursement plan)

If you’re unsure about your eligibility, our tax management services can assess your case and help you claim every legal deduction.

Standard Mileage Rate vs. Actual Expense Method: What’s Better?

You can choose between two deduction methods:

1. Standard Mileage Method

• Multiply total business miles by the IRS rate (70¢/mile in 2025)
• Easier to calculate
• You can’t deduct gas, insurance, or repairs separately

2. Actual Expense Method

• Deduct a portion of actual car-related expenses (fuel, insurance, repairs, lease)
• You must track all expenses and allocate the business-use percentage

To determine which works best for you, we’ll walk you through both as part of our bookkeeping support.

How to Track Mileage for Tax Deductions (Without Mistakes)

Poor mileage logs are one of the top red flags during IRS audits. Avoid errors by:

• Recording date, destination, purpose, and miles
• Separating personal and business miles
• Using trusted apps like MileIQ, Everlance, or QuickBooks Self-Employed

Mileage logs also support clear financial reporting, especially during quarterly or annual reviews.

Reporting Mileage on Your Tax Return: A Step-by-Step Guide

Depending on your business structure, here’s where mileage deductions go:

• Sole Proprietors: Form 1040 Schedule C
• S-Corp / C-Corp: Reimbursements reported via payroll (see your payroll services provider)
• Partnerships: Partners use Schedule E for unreimbursed business expenses

Need help filing correctly? Our tax management services ensure every mile is accounted for.

IRS Mileage Rules for Employees, Contractors, and Business Owners

Self-employed? You can deduct mileage for:

• Client meetings
• Business errands (e.g., banking, supply runs)
• Travel between job sites

Employees? You must use an Accountable Plan through your employer to receive tax-free mileage reimbursements. This is typically handled via payroll services.

Gig worker or freelancer? You still qualify — and we can help you record, report, and defend every mile.

FAQs About IRS Mileage Rates and Tax Deductions

Q1: Can I deduct commuting miles from home to my office?
No. The IRS doesn’t allow deductions for commuting. Only business-related travel counts.

Q2: Do I need receipts for gas if I use the standard mileage rate?
No. The rate covers gas, maintenance, depreciation, etc.

Q3: Can I switch between methods each year?
Yes — unless you’ve claimed depreciation under the actual method in a prior year, which limits switching.

Q4: Are electric vehicle miles deductible?
Yes, the same rules apply. But fuel costs (charging) are not separately deductible if using the standard method.

Q5: What if I get audited?
You’ll need a complete mileage log. We prepare audit-proof logs as part of our bookkeeping and accounting services.

YoY Growth Formula Explained: How to Calculate Year-over-Year Growth for Business Success

by stiusallc | Jun 30, 2025 | Blog

Year-over-year (YoY) growth is one of the most trusted metrics for measuring a business’s long-term success. Whether you’re a small business owner, CFO, or growth strategist, understanding this formula can help you assess performance trends and improve decision-making. More importantly, for firms offering accounting services, it’s an essential tool to evaluate financial health and guide future strategies.

What Is YoY Growth and Why Is It Important?

Year-over-year growth compares a specific financial metric (such as revenue, expenses, or net income) from one period to the same period the previous year. This approach minimizes seasonal distortions and provides a more consistent view of a company’s performance over time.

Unlike month-over-month comparisons, YoY metrics offer clearer insight into annual performance trends—making them vital in financial reporting and growth forecasting tools.

YoY Growth Formula: The Basics

The YoY growth formula is straightforward:

YoY Growth (%) = [(Current Year Value − Previous Year Value) / Previous Year Value] × 100

Example:

• January 2025 Revenue = $60,000
• January 2024 Revenue = $48,000
• YoY Growth = (($60,000 – $48,000) / $48,000) × 100 = 25%

This means revenue increased by 25% compared to the same month last year.

How Different Industries Use YoY Growth

Ecommerce:

• Q1 2025 Sales: $500,000
• Q1 2024 Sales: $400,000
• YoY Growth = 25%

SaaS:

• MRR in May 2025: $45,000
• MRR in May 2024: $30,000
• YoY Growth = 50%

Retail:

• Net income on Black Friday 2024: $80,000
• Black Friday 2023: $60,000
• YoY Growth = 33.3%

Such growth trends are often integrated into financial dashboards provided through professional accounting services.

Advanced Variations of YoY Growth

While the standard YoY formula is useful, there are advanced variations:

• Trailing 12-Month (TTM) YoY: Measures the most recent 12 months against the 12 before that.
• Compound Annual Growth Rate (CAGR): Smooths out growth over multiple years.
• YoY vs. Sequential Growth: While YoY compares the same period year over year, sequential growth looks at consecutive periods (e.g., Q1 to Q2).

These metrics support deeper performance evaluation and are critical for services like tax planning and financial forecasting.

Implementing YoY in Your Reporting

To start using YoY growth:

• Collect historical data from reliable bookkeeping services
• Choose comparison periods (monthly, quarterly, or annually)
• Apply the formula using spreadsheet software or accounting platforms
• Visualize the data through trend charts or financial dashboards

Including YoY analysis in your financial reporting allows businesses to identify seasonal patterns, forecast revenue, and make better investment decisions.

Sample YoY Growth Table

Visual tools like this are often part of business advisory and accounting software solutions.

FAQs

Q1: What is the YoY growth formula?
YoY Growth (%) = ((Current Period – Previous Year Same Period) / Previous Year Same Period) × 100

Q2: Why is YoY growth better than MoM?
It eliminates seasonal bias and provides a more stable view of performance trends over time.

Q3: Can YoY be used for cost analysis?
Yes. Compare yearly expenses to monitor cost control, especially in payroll services or overhead.

Q4: Is YoY relevant for small businesses?
Absolutely. It provides insights that can guide decisions around bookkeeping services, marketing spend, and hiring.

Q5: How does YoY growth support financial planning?
It helps accountants and clients forecast revenue and expenses, informing tax planning services and investment decisions.

Conclusion: Why YoY Growth Matters

Understanding and applying the YoY growth formula can dramatically improve your business’s ability to interpret long-term performance. It simplifies reporting, enhances investor communications, and helps in forming smarter strategies.

If you’re looking to integrate YoY analysis into your business reporting, our expert team at Smart Accountants can help you track key metrics, identify patterns, and make data-driven decisions.
