S-Corp Bookkeeping Services
S-CORP BOOKKEEPING THAT KEEPS THE TAX SAVINGS
Electing S-Corp status saves you money on self-employment tax. Sloppy bookkeeping gives those savings back to the IRS in audit penalties. We track W-2 salary separately from owner distributions, document reasonable compensation, prep PA-20S/PA-65 information returns, and recalculate quarterly estimated taxes the way an S-Corp election actually requires. Certified QuickBooks ProAdvisor based in Cranberry Township, serving S-Corps and LLCs taxed as S-Corps across Pittsburgh, Butler County, and the North Hills.

WHAT YOU GET
The Process
HOW IT WORKS
Free Diagnostic Call
We start with a 30-minute call to understand your S-Corp setup. Are you a true S-Corp (incorporated and elected) or an LLC taxed as S-Corp? Is payroll already running through Gusto, ADP, or another provider, or are you still pulling distributions and calling them salary? Do you have reasonable comp documented anywhere? We'll tell you what's already working and what needs to be fixed before we go on a monthly plan. No cost, no commitment.
Setup or Cleanup First
If you just elected S-Corp status, we set up QuickBooks with the right chart of accounts, integrate it with your payroll provider, and document reasonable comp for the year. If your books have been running but the salary-vs-distribution split is a mess, we quote a one-time cleanup before going monthly. The cleanup is a flat fee based on scope. You'll know the exact cost before we start.
Monthly Bookkeeping with S-Corp Specifics
Every month we reconcile your accounts, post W-2 salary entries from payroll, track owner distributions in their own equity account, calculate estimated quarterly taxes on both salary and distributions, and produce a clean P&L and Balance Sheet. Reasonable comp tracking gets reviewed quarterly so you can adjust salary if profit projections shift. You get the reports your CPA needs and the documentation you'd need if the IRS ever asked questions.
Year-End K-1 Prep and 1120-S Handoff
At year-end we prep K-1s for each S-Corp shareholder (Form 1120-S Schedule K-1) and PA Schedule RK-1 for the PA-20S/PA-65 information return. Your CPA files Form 1120-S federally and PA-20S/PA-65 in Pennsylvania. We also prepare the accountable plan reimbursement summary, the reasonable comp documentation packet, and any other backup your CPA needs. Tax season takes days, not weeks.

The Impact
WHY IT MATTERS
S-Corp election is one of the highest-leverage tax decisions a profitable business owner can make. It saves real money on self-employment tax (the 15.3% Social Security and Medicare hit that LLCs and sole proprietors pay on every dollar of profit). On $100,000 of business profit, electing S-Corp status and paying yourself a $50,000 salary instead of $100,000 of self-employment income can save roughly $7,000 in SE tax per year. That's the math that drives the election. Here's the problem most S-Corp owners don't realize until the IRS comes asking: those tax savings are conditional. They depend entirely on whether your bookkeeping documents what you actually did. The IRS audits S-Corps specifically for reasonable compensation issues. If you took $30,000 in salary and $70,000 in distributions on a $100,000 profit business, the IRS can argue your salary should have been $60,000 and reclassify the difference as wages, owing back-payroll-tax plus penalties plus interest. We've seen this hit. A Pittsburgh consultant came to us after the IRS reclassified two years of distributions. The owner had been taking minimal salary and large distributions because the previous bookkeeper didn't document reasonable comp. Total back-tax bill plus penalties: just over $19,000. Cleaner bookkeeping wouldn't have made the IRS audit go away, but it would have given the consultant a defensible position. Without it, there was nothing to argue with. The bookkeeping for an S-Corp is fundamentally different from an LLC taxed as a sole proprietor or partnership. With an S-Corp you have to run yourself on W-2 payroll, which means a payroll provider (Gusto, ADP, OnPay, Patriot are common), tax withholding on every paycheck, quarterly federal payroll filings (Form 941), state unemployment filings (Form UC-2 and UC-2A in PA), and W-2 issuance at year-end. That payroll runs through QuickBooks and has to reconcile with your distributions, which are separate equity transactions, not expenses. The chart of accounts has specific S-Corp accounts (Officer Compensation, Shareholder Distributions, Accountable Plan Reimbursements) that don't exist on a simpler entity's books. Most generic bookkeepers miss these. Reasonable compensation is the term that comes up in every IRS S-Corp audit. The IRS doesn't define a specific number. Instead they look at industry comparables, your role, hours worked, and the size of the business. The most defensible documentation is a written reasonable comp study, often using data from RCReports or BBSI, that shows what someone in your role and industry would earn at a comparable company. We can run a simplified internal version, or we coordinate with your CPA on a formal reasonable comp study for higher-risk situations. Either way, the documentation needs to exist BEFORE you take distributions, not after the audit notice arrives. Pennsylvania adds specific compliance steps S-Corps owe that LLCs don't. PA requires S-Corps to file PA-20S/PA-65 (the same form used for partnerships) as an information return, with each shareholder receiving PA Schedule RK-1 showing their share of PA-source income. Pennsylvania does NOT recognize the federal S-Corp election by default. PA treats S-Corps as pass-through entities for income tax (similar to federal), but you must file PA Form REV-1640 to make the PA S-Corp election for state purposes if you want PA to follow the federal treatment. We track all of this and coordinate with your CPA so you don't end up paying state corporate net income tax by accident. The S-Corp election threshold question comes up every time someone considers the move. As a rule of thumb, electing S-Corp status starts to make financial sense when your LLC or sole proprietorship is netting somewhere in the $40,000 to $60,000 per year range. Below that, the cost of running payroll, filing additional returns, and maintaining reasonable comp documentation often eats the SE tax savings. Above $60,000, the math usually favors S-Corp election once you account for ongoing compliance. We can run the actual numbers for your situation during the diagnostic call so you're not guessing. The S-Corp election itself (Form 2553) is a CPA filing. We handle everything that comes after, including the chart of accounts changes, the payroll integration, the reasonable comp setup, and the quarterly estimated tax recalculation. On the platform question: we work with QuickBooks Online for almost every S-Corp client because Online integrates cleanly with Gusto, ADP, OnPay, and Patriot for payroll. The integration matters because every payroll run posts journal entries to QuickBooks automatically (gross wages, employer taxes, employee tax withholdings) and you don't want to be hand-keying that every two weeks. We set up the integration during onboarding. You'll have books that document the S-Corp election in a way that survives an IRS audit, payroll that runs cleanly without you thinking about it, and a clear separation between W-2 wages and shareholder distributions that holds up in any review. The election saves real money. We make sure the savings stay yours.

FREQUENTLY ASKED QUESTIONS
Significant. An LLC taxed as a sole prop or partnership has owner draws and capital contributions, no payroll, and a simpler chart of accounts. An S-Corp (or LLC taxed as S-Corp) has W-2 payroll for the owner, owner distributions tracked separately from salary, accountable plan reimbursements, reasonable compensation documentation, and a chart of accounts with S-Corp-specific equity accounts. The transactions look different, the year-end filings are different (Form 1120-S vs Schedule C or PA-65), and the audit risks are different. If you've elected S-Corp status, the bookkeeping needs to reflect that, otherwise you can lose the tax savings the election was supposed to create.
Reasonable compensation is the salary the IRS expects an S-Corp owner to pay themselves before taking any distributions. It's the single biggest audit trigger for S-Corps. The IRS doesn't publish a specific number. Instead they look at what someone in your role, industry, and region would earn at a comparable company doing comparable work. If your salary is too low (and your distributions too high) relative to that benchmark, the IRS can reclassify your distributions as wages, owing back-payroll-tax plus penalties plus interest. Documentation matters. We help you build the documentation BEFORE distributions go out, not after the audit notice arrives.
There's no single right answer. The IRS expects reasonable compensation, which depends on your industry, role, hours worked, and business size. A common rule of thumb is the 60/40 ratio (60% salary, 40% distributions) for service-based S-Corps with modest profit, but the actual number depends on the comparables for your specific role. For higher-risk situations (high distributions or large profit), we recommend a formal reasonable comp study through RCReports or BBSI, which uses regional and industry-specific salary data. We can do a simplified internal version or coordinate with your CPA on the formal study.
Yes. The IRS requires S-Corp owners who provide services to the company to be paid as W-2 employees, not just as distribution recipients. That means a payroll provider (Gusto, ADP, OnPay, Patriot are common), tax withholding on every paycheck, quarterly federal payroll filings (Form 941), state unemployment filings (Form UC-2 and UC-2A in PA), and W-2 issuance at year-end. We integrate your payroll provider with QuickBooks during onboarding so the entries post automatically.
Pennsylvania does NOT automatically follow the federal S-Corp election. To get PA to treat your business as an S-Corp for state income tax (pass-through to shareholders rather than corporate net income tax), you must file PA Form REV-1640. Once elected, your S-Corp files PA-20S/PA-65 as an information return each year, and each shareholder receives PA Schedule RK-1 showing their share of PA-source income. We coordinate with your CPA on the PA election filing if it hasn't been done, and we handle the bookkeeping work that supports the annual PA-20S/PA-65 filing.
As a rule of thumb, electing S-Corp status starts to make financial sense when your business is netting somewhere in the $40,000 to $60,000 per year range. Below that, the cost of running payroll (typically $40-80/month), filing additional federal and state returns, and maintaining reasonable comp documentation often eats the self-employment tax savings. Above $60,000, the math usually favors S-Corp election. We can run the actual numbers during the diagnostic call so you can decide whether the election makes sense for your specific situation. The election itself (Form 2553) is your CPA's filing. We handle the bookkeeping side.
An accountable plan is an IRS-approved arrangement that lets your S-Corp reimburse you for legitimate business expenses (home office, mileage, cell phone, internet) tax-free, instead of you deducting them personally. For S-Corps it's a clear win because the company gets the deduction and you get the reimbursement without it counting as additional wages. We set up the accountable plan documentation during onboarding and track reimbursements monthly so the records exist if anyone asks.
Yes, and this is one of the most common setups we see. An LLC that elects S-Corp tax treatment (by filing Form 2553) gets the legal flexibility of an LLC plus the SE-tax savings of an S-Corp. The bookkeeping looks like S-Corp bookkeeping (W-2 payroll, distributions, reasonable comp, K-1 prep) but the legal entity remains an LLC. We see this constantly with profitable single-member and multi-member LLCs. See our LLC bookkeeping page for the LLC-specific compliance side, and this page for the S-Corp tax-treatment side. We handle both together.
Our Growth plan starts at $599/month and is the natural fit for most S-Corps because it includes payroll support and quarterly advisory calls (which S-Corps need for reasonable comp reviews). Scale at $1,199/month is for established S-Corps with multiple entities, higher complexity, or fractional CFO needs. If your books need a one-time cleanup before going monthly (common for S-Corps that have been DIY for a few years), we quote that as a flat fee separately. No hourly billing, no surprise invoices.
We can fix it. This is one of the most common cleanup issues we see in S-Corp bookkeeping, because the previous bookkeeper or the owner didn't understand the equity account structure. We rebuild the chart of accounts, reclassify the distributions to the proper Shareholder Distributions equity account, document reasonable comp retroactively where possible, and produce corrected financial statements. We coordinate with your CPA on whether amended returns are needed. Multi-year S-Corp cleanups typically run between $1,800 and $5,000 as a flat fee.
