Phase 10: Operate

Operating a Tax Preparation Service

3 min readUpdated September 2026

Operating a tax prep business means running two very different operating modes in the same year: an intense, capacity-constrained 10-12 week filing season where staffing and throughput dominate everything, and a quieter off-season where the focus shifts to the complementary services that keep the business viable year-round.

Season Staffing Has to Be Planned Months in Advance, Not in January

A single preparer can typically complete 6-10 returns per day during peak season depending on return complexity, which sets a hard ceiling on how many clients one person can serve in a 10-12 week window. If your client volume approaches that ceiling, you need seasonal preparers, often part-time, contracted specifically for tax season, hired and trained by December, since finding and onboarding qualified seasonal preparers in January, when demand for them spikes across the industry, is far harder and more expensive.

Due Diligence Documentation Protects You From IRS Preparer Penalties

IRS due-diligence requirements, particularly around credits like the Earned Income Tax Credit and Child Tax Credit, require preparers to document the basis for claiming certain credits, not just file the return; failing to maintain this documentation can result in per-return penalties assessed directly against the preparer, separate from any issue with the client's own return. Build a standardized documentation checklist into your workflow for every return claiming these credits, rather than relying on memory during your busiest weeks.

Off-Season Revenue Requires a Deliberate Plan, Not an Afterthought

The months after April are when tax-only practices often see revenue drop to near zero, so successful practices build a deliberate off-season offering: quarterly estimated tax planning for self-employed clients, bookkeeping retainers, amended return and IRS notice resolution work, or tax planning consultations for clients considering a business structure change. Start marketing and delivering these services well before the current tax season ends, using your existing client relationships, rather than waiting until May to figure out what the off-season business looks like.

Manage Extension Filings and the Second, Smaller Deadline Wave Deliberately

Clients who file extensions create a second, smaller crunch around the October extended deadline, and treating this as an afterthought after the April rush leads to disorganized files and rushed work on returns that were often complex enough to need the extension in the first place. Build a specific process for tracking extended returns throughout the summer, following up with clients for missing documents well before September, and staffing appropriately for the October push so it doesn't become a repeat of the April scramble on a smaller but still meaningful scale.

Build a Client Communication Cadence That Survives the Busiest Weeks

During peak season, client communication can easily become reactive, only responding when a client calls anxious about their return's status, which creates unnecessary phone volume that eats into preparer time better spent on actual returns. Build a proactive status-update cadence, even a simple automated email when a return moves to a new stage, review, filed, refund status, that reduces inbound status-check calls and improves the client experience without adding staff time. Practices that communicate proactively during the crunch consistently report fewer frustrated client calls and better client retention year over year than practices that only communicate when a client initiates contact, since tax clients are often anxious about money and appreciate visibility into where their return stands even when there's nothing wrong.

Maintain Data Security Given the Sensitivity of Client Information

Tax preparers handle some of the most sensitive personal financial information clients have, Social Security numbers, income details, bank account numbers, and the IRS has specific data security plan requirements, an IRS-mandated Written Information Security Plan, that every paid preparer must maintain, not just larger firms. Build secure document handling into your operational workflow from day one, encrypted client portals rather than email attachments for sensitive documents, secure storage and disposal practices for physical documents, since a data breach at a small tax practice can be just as damaging to your reputation and just as legally consequential as one at a larger firm, and clients increasingly expect secure handling as a baseline, not a premium feature.

Build Continuing Education and Tax Law Updates Into Your Annual Calendar

Tax law changes yearly, sometimes significantly, and preparers who don't build a deliberate annual process for reviewing changes before the season starts risk both compliance errors and missed planning opportunities for clients. Block dedicated time each fall, well before the season's crunch begins, to review the current year's tax law changes, complete required continuing education for your credential, and update your internal checklists and software configuration accordingly, since trying to absorb significant tax law changes reactively in the middle of a fully booked filing season is both stressful and a real source of preparer error.

FREQUENTLY ASKED QUESTIONS

How many returns can one preparer handle during peak season?

Roughly 6-10 returns per day depending on complexity, which over a 10-12 week season translates to a few hundred returns per preparer; more complex business and rental-property returns push this toward the lower end of that range.

What happens if I don't maintain due-diligence documentation for credit-related returns?

The IRS can assess per-return penalties directly against the preparer for failing to meet due-diligence requirements on returns claiming certain credits, independent of whether the underlying claim itself was accurate, so this documentation is a compliance requirement, not an optional best practice.

What's the most common off-season service tax preparers add?

Bookkeeping and quarterly estimated tax planning for self-employed and small-business clients is the most common addition, since it uses the same client relationships and much of the same underlying knowledge, and creates a natural touchpoint that also improves next season's tax prep engagement.

How should I handle the October extension deadline differently from the April rush?

Start tracking extended returns and following up on missing documents throughout the summer rather than waiting until September, and staff appropriately for the smaller but still real October crunch, since extended returns are often the more complex ones that needed the extra time in the first place.
