Tax Services for Small Business in 2026

No single income floor applies to every business. Whether you must file depends on the entity, how it's taxed, and whether it had net earnings, payroll, sales tax or other reportable activity. Sole proprietors, for instance, owe self employment tax once net self employment earnings reach $400. Partnerships and corporations generally file an annual return even in a year with little income or a loss.

Running personal spending through the business account, losing receipts, treating employees as contractors, missing payroll deposits and only looking at the numbers in March. A big one we see often: owners type figures into tax software straight from bank totals without reconciling the books, or roll forward last year's balances without checking them. Late filings and ignored notices then add penalties and interest on top.

Figure out which federal return your entity files: Schedule C for most sole proprietors, Form 1065 for partnerships, Form 1120 or 1120-S for corporations. Reconcile income, expenses, payroll and asset purchases before anything goes into the software. Compare the draft return with your financial statements and last year's return, then file by the deadline. If there are old years open or IRS balances, sort out compliance first.

Payroll platforms can calculate withholding, produce Forms 941 and W-2 and schedule deposits, but you still own the data, the timing and how each worker is classified. When something slips, payroll tax problems grow faster than almost any other tax issue, and the Trust Fund Recovery Penalty can reach owners personally. If you already have a 941 balance, late deposits or IRS letters, software won't fix that. Payroll tax resolution will.

Every income record, bank and credit card statements, invoices, receipts, payroll reports, loan statements, last year's return and paperwork for equipment or other asset purchases. Reconcile each account so the software gets actual figures, not estimates. Keep support for deductions, owner contributions and distributions. Clean, reconciled books make the return more accurate and make any IRS question much easier to answer.

You can, but it's risky to treat each year in isolation. Filing several years together changes the total balance, penalties, interest and which collection options remain open. Each missing year needs complete records and all the related federal filings, payroll returns included. We prepare delinquent business returns as part of a plan for resolving whatever the IRS says you owe.

Read it, find the response deadline, and compare what the IRS says with your return, payment history and records. Respond even if you think the IRS is wrong. Some letters only ask for information, while others propose changes, demand payment or warn of levy action. Keep copies of everything.

When the questions need judgment instead of math. Common tipping points: several entities, payroll tax balances, unfiled years, an audit, real back taxes, cross border income, or a federal contract that brings DCAA and FAR cost rules. At that stage you usually want a professional reviewing the books, and possibly a fractional CFO, with the software as the tool underneath.
