Extension season for a CPA firm

An example engagement for accounting firms in Houston.

This is an example engagement, not a client story. It shows how we would run an audit and build for a typical firm of this kind. The research figures come from the public sources cited, and nothing here reports a specific client's results.

A Houston CPA firm with several preparers that files a large share of individual and business returns on extension each year.

In April, extensions are filed in a rush and tracked in a spreadsheet. Over the summer, nobody follows up with clients for the missing pieces, so September and October become a second tax season.

Some clients assume an extension also delays their payment and are surprised by interest. When the IRS postpones deadlines after a Gulf Coast storm, the firm has to work out by hand which clients the relief covers.

What the research says02

An individual filing extension moves the filing deadline to October 15, but it is not an extension of time to pay. Tax owed is still due by the April deadline, and interest runs on any unpaid balance.

After Hurricane Beryl in July 2024, the IRS postponed various deadlines to February 3, 2025 for taxpayers in 67 Texas counties, including Harris County. That covered individual returns on extension originally due October 15, 2024, and estimated tax payments due September 16, 2024 and January 15, 2025.

Audit, build, measure03

What the audit checks

  • List every extended return from last year and when its documents actually arrived.
  • Review what clients are told about payment when an extension is filed.
  • Check how the firm tracked last year's disaster postponements and which clients they covered.
  • Measure preparer workload by week from July through October.
  • Rank fixes by hours saved in the final weeks and by penalty risk reduced.

What we build

What we measure

  • Extended returns with complete documents by September 1
  • Returns filed in the final two weeks before October 15
  • Client questions about extensions and payment
  • Time to identify clients covered by a disaster postponement

Every measure starts from the firm's own baseline, taken during the audit, so results are compared with how the firm ran before anything changed.

Tax season document collection for a CPA firm

A small CPA firm spends tax season chasing clients for missing documents. The fix is automatic reminders that follow up until files arrive, plus intake and file search.

Month-end close for a bookkeeping firm

A bookkeeping firm closes the month late because client answers and receipts trickle in. The fix is automatic requests for missing items, clearer work assignment, and reports that build themselves.
