Why it matters

Small businesses face the same federal tax rules and many of the same penalties as larger firms. A focused compliance risk assessment highlights where errors or gaps are likely (payroll deposits, filing returns, sales tax, licensing) and builds fixed processes to prevent costly remediation, audits, and fines. In my practice working with over 500 small businesses, early detection and simple controls have saved clients thousands and reduced stress during examinations.

A starter plan — four practical steps

  1. Identify applicable rules
  • List federal, state and local obligations that apply to your business (e.g., income tax, payroll taxes, sales/use tax, licensing, industry rules). Use IRS Employer resources (Publication 15 and Form 941 guidance) for payroll basics (see IRS resources below).
  1. Evaluate where you’re vulnerable
  • Review recent filings, payment histories, and bookkeeping for mistakes or late activity. Score risk by likelihood (rare → frequent) and impact (minor paperwork → major penalties or stoppage of operations).
  1. Implement simple controls
  • Standardize tasks: calendar tax due dates, require two-person review for payroll and tax filings, lock down who can authorize bank debits, and set automated reminders. Use accounting software with audit trails and integrate EFTPS for payroll deposits.
  1. Monitor and adapt
  • Schedule quarterly checks of controls and an annual full reassessment whenever you add employees, change payroll methods, or launch new products or locations.

Practical tools and resources

  • IRS Publication 15, Employer’s Tax Guide — for withholding, deposits, and employer responsibilities (irs.gov/publications/p15).
  • IRS Form 941 guidance — to understand quarterly reporting requirements (irs.gov/forms-pubs/about-form-941).
  • EFTPS — use for reliable federal tax deposits (eftps.gov).
  • Small Business Administration (sba.gov) — for state/local contacts and licensing guidance.

Short example

A small retail client missed a seasonal sales spike and underwithheld payroll taxes for two quarters. We implemented a two-step payroll approval, switched to biweekly reconciliations in accounting software, and set up EFTPS deposits. The change eliminated missed deposits and reduced the client’s exposure to the Trust Fund Recovery Penalty.

Common mistakes

  • Treating compliance as a year-end task rather than ongoing operations.
  • Relying on a single person for filing and payments (no checks and balances).
  • Ignoring state/local tax or licensing differences when expanding.

Quick starter checklist (one-page)

  • Create a compliance calendar with all federal, state, and local due dates.
  • Reconcile payroll and bank accounts monthly.
  • Require dual review for tax filings and bank authorizations.
  • Keep documentation for at least three years; retain payroll records per IRS guidance.
  • Meet with a CPA or enrolled agent at least annually.

Professional tips

  • Automate what you can (payroll, deposits, reminders) to reduce human error.
  • Build relationships with one CPA or tax advisor who understands your industry; that continuity pays off.
  • Document processes in a short operations manual so staff can follow consistent steps.

FAQs (brief)

When should I reassess?

  • Annually and whenever you add employees, change payroll providers, open a location, or adopt new revenue streams.

Can I do this without a CPA?

  • You can start on your own, but a CPA or tax practitioner helps prioritize risks and represent you during an audit.
