Restaurants, contractors, nail salons, food trucks, retail cash operations—these businesses face more IRS scrutiny than businesses that process most transactions digitally. It's not a presumption of guilt. It's a recognition that cash is harder to trace, and the IRS has developed specific methods for reconstructing income when books and records don't tell the full story. Knowing those methods helps you understand what your records need to prove. Why Cash Businesses Draw More

The Tax Cuts and Jobs Act introduced a limitation that surprises many business owners who have a large loss year: the excess business loss limitation under IRC §461(l). In plain English, this rule can stop you from using all of your business loss against other income in the current year. That does not mean the loss disappears. It means part of the deduction may be delayed and carried forward. This is one of the reasons tax planning across years matters. A loss year is not jus

The Offer in Compromise is one of the most misunderstood and oversold products in the tax resolution industry. The ads promise pennies on the dollar. The reality is a financial analysis where the IRS calculates how much it believes it can reasonably collect from you over the remaining collection period—and if that number is at least as large as your balance, your offer will be rejected. Here's how the IRS actually evaluates one. What an OIC Is An Offer in Compromise is an agr

Pass-through losses from an S-Corp or partnership flow through to your personal return on Schedule K-1. But a K-1 loss doesn't automatically translate into a deduction. Multiple limitation systems — including basis, at-risk, and passive activity loss rules — can block or defer that deduction, sometimes for years. Understanding how these work prevents surprises on your return and helps you plan around them. Basis Limitations In an S-Corp or partnership, your ability to deduct

If you're self-employed and paying for your own health insurance, you may be entitled to deduct 100% of your premiums without itemizing. It's one of the few above-the-line deductions that directly reduces your adjusted gross income, which can ripple through your entire return—affecting other calculations on the return, including QBI in some cases, eligibility for certain credits, and ultimately your tax bill. Many business owners either miss this entirely or set it up incorre

Starting a business often means losing money before making it. The IRS actually accounts for this. The Net Operating Loss (NOL) rules allow you to offset future profitable years with losses from less profitable ones—which is one of the reasons tax planning across years matters more than looking at any single year in isolation. What Is an NOL? A Net Operating Loss can occur when allowable deductions exceed income for the year, after the NOL rules make specific adjustments. Not

S-Corp owners often pay for business expenses out of pocket—mileage, home office, phone, supplies—and then either forget to reimburse themselves or run expenses through the S-Corp account in ways that create tax problems. An accountable plan solves this. It's not complicated, but getting it wrong costs money, and most S-Corp owners either don't have one at all or have one that doesn't actually work. Why This Matters for S-Corp Owners Specifically Unlike a sole proprietor, an

Making the S-Corp election is theoretically straightforward: file Form 2553, get confirmation, done. In practice, Form 2553 has a surprising number of failure points, and many business owners don't discover the problem until they're mid-audit or trying to prepare returns years after the fact. Here's where the election goes wrong. Missing the Filing Deadline For a calendar-year entity, the S-Corp election is generally due no more than 2 months and 15 days after the beginning o

Starting a business costs money before you make any. Market research, legal fees, training, licenses, state filing fees—all of this happens before you open. The IRS has specific rules for how these pre-opening costs are treated, and a lot of new business owners either miss the deduction entirely or get the timing wrong. Here's how it actually works. What Are Startup Costs? Startup costs are amounts paid or incurred to investigate the creation of an active business or to creat

Most people use lien and levy interchangeably. In IRS collection, they are not the same thing—not even close. The confusion matters because the correct response to each is completely different, and getting them mixed up means you're solving the wrong problem. What a Federal Tax Lien Is A federal tax lien is a legal claim the IRS places against all of your property—real estate, financial accounts, personal property, business assets—to secure a tax debt. It's a public notice th

There has been a lot of confusion around Form 1099-K over the last few years. For a long time, many small sellers and freelancers only received Form 1099-K if they had more than $20,000 in payments and more than 200 transactions through a third-party payment platform. Then the threshold became a moving target, which created a lot of panic and bad information online. But the more important point never changed: The 1099-K does not create the tax liability. The income does. If y

Retirement planning is one of the few areas where the tax code is genuinely trying to help you. As a self-employed business owner, you have access to retirement vehicles that allow you to contribute significantly more than a traditional employee—and, in many cases, deduct contributions within IRS limits. The three most common options for small business owners are the SEP-IRA, the Solo 401(k), and the SIMPLE IRA. Each one fits a different situation. SEP-IRA (Simplified Employe

If your business owes payroll taxes, you might assume that's a business problem. The IRS disagrees. Under the Trust Fund Recovery Penalty (TFRP), the IRS can assess the unpaid employee portion of payroll taxes directly against individuals—piercing through the business entity entirely and going after personal assets. This is one of the few places in tax law where the protection a business entity normally provides simply disappears. What Are Trust Fund Taxes? When you run payro

Closed sign Closed sign Closing a business isn't just a business decision—it's a tax event. The IRS has specific expectations for what needs to happen when you shut down operations, and skipping these steps creates problems that follow you long after the doors close. Most owners focus on the operational side and never think through the tax side until it's too late. Filing Final Returns Every entity type has a required final return process. For a sole proprietor filing on Sche

S-corps are one of the IRS's most consistent examination targets in the small business space. The reason is straightforward: owner compensation is the primary mechanism through which S-corp owners avoid self-employment tax on business income, and the IRS knows it's frequently abused. Here's what triggers scrutiny, what agents look at during an S-corp payroll examination, and what makes a defensible position. How S-Corp Owners Get Selected The IRS uses automated scoring system

A lot of small business owners do their own bookkeeping, especially early on. It makes sense at the start — the transaction volume is low, the categories are simple, and paying someone to do it feels like an unnecessary overhead. But as the business grows, that calculation changes. And most owners don't realize it until the cost has already been paid. The Time Cost Is Larger Than It Looks Small business owners consistently underestimate how long bookkeeping takes. Logging tra

The Section 199A qualified business income deduction is now permanent. For pass-through business owners — sole proprietors, S-corps, partnerships — it's worth up to 20% of qualified business income. It's one of the most valuable deductions available to small business owners. It's also one of the most commonly miscalculated. Let's put a number on what a planning error here actually costs over time. How the Deduction Works (Briefly) QBI is the net income from a qualified trade

A refund feels like a passing grade. It means you paid more than you owed, the IRS processed your return, and you're getting money back. For most people, it signals: no problems here, move on. That's not how it works. What a Refund Actually Means A refund is a cash flow calculation — it reflects the difference between your tax liability and what you prepaid through withholding or estimated payments. It says nothing about whether the return was prepared correctly. You can have

Starting the process with a tax or bookkeeping firm should not require phone tag. Many small business owners reach out when something already feels messy. The books may be behind. A tax return may need to be filed. An IRS notice may have arrived. Or there may simply be a question that is too detailed to explain well in a voicemail. That is why Zero Fluff Books now allows prospective clients to begin through our secure online intake portal. This change is not about making the

If you're in a partnership — or an LLC taxed as a partnership — there's a number you're supposed to be tracking every year. It's called your outside basis. Most partners have no idea what it is. And the IRS doesn't track it for you. The consequences of ignoring basis don't always show up immediately. They accumulate quietly over years, and then they surface at exactly the worst time: when you sell your interest, when you receive a large distribution, or when the partnership g
