Is Your Tax Deadline at Risk Because Your Books Are Behind?

Tax filing deadlines don't negotiate. If your books are incomplete, incorrectly coded, or missing reconciliations, you risk penalties, extension fees, and the kind of red flags that turn a routine filing into an audit conversation.

A full multi-year clean-up can take months — time you don't have before April 15th or your extension deadline. Most businesses in this position don't need every ledger entry from the last three years rebuilt. They need the accounts that feed the tax return fixed, fast.

KnowVisory's tax-season clean-up focuses on what filing actually demands: accurate accounts payable and receivable, correct general ledger coding, complete bank reconciliation, and verified payroll tax liabilities. We prioritize by tax impact, not by chronology.

Our Tax-Season Clean-Up Process: Fast-Track to Filing Ready

Week 1–2: Triage & Prioritization
We audit your general ledger and AP/AR ledgers, identify the tax-critical errors first — missing vendor invoices, payroll accruals, revenue misstatements — and build a sequenced fix list.
Week 3–4: High-Impact Fixes
We reconcile bank and credit card statements, correct coding on material transactions, verify payroll tax liabilities and W-2 readiness, and validate sales tax accruals.
Week 5–6: Trial Balance & Final Review
We prepare a clean trial balance, flag remaining discrepancies for your CPA or tax team, and deliver audit-ready support documentation.
Throughout: Integration With Your Systems
We work inside your existing QuickBooks, Xero, NetSuite, or Zoho Books instance without disrupting live operations or requiring a platform switch.

What We Fix First (and Why)

Not every error carries the same tax risk. We work in this order because this is the order the IRS and your CPA will check.

Bank & Credit Card Reconciliation

Unmatched transactions hide fraud, coding errors, and cash-flow distortions that auditors and the IRS expect verified before a return is filed.

Payroll Tax Liabilities & Accruals

Missing or understated payroll taxes, benefits withholdings, and W-2 accruals trigger penalties fast and are the first thing a payroll tax audit examines.

Accounts Payable Aging & Cutoff

Year-end AP cutoff errors distort both the balance sheet and expense allocation. We match invoices to receiving records and post them in the correct period.

Revenue Recognition & Coding

For SaaS, professional services, and e-commerce businesses, revenue timing and allocation mistakes flow straight into tax liability. We correct these before anything else touches the P&L.

Fixed Asset Disposals & Depreciation

Sold or scrapped assets still sitting on the books, or missing asset tags, create reconciliation blocks. We audit and clear the fixed asset register before year-end close.

Why Speed Without Sacrifice

A rushed clean-up done wrong costs more than the deadline you were trying to hit. Here's the difference between our approach and a general full-scope clean-up.

Tax-Season Bookkeeping Clean-Up: Common Questions

How quickly can you clean up my books before tax season?

Most tax-critical clean-ups run 3 to 6 weeks depending on how many months are behind and how many accounts need reconciliation. Simple cases — a few months of unmatched invoices or missing bank recs — can close in 2 weeks. We scope the exact timeline in the first consultation once we've seen your books.

What's the difference between a tax-season clean-up and a full catch-up bookkeeping service?

A full catch-up service rebuilds every transaction across all the months or years you've fallen behind, regardless of tax impact. A tax-season clean-up prioritizes only the accounts that feed your tax return — bank reconciliations, payroll liabilities, AP/AR cutoff, and revenue coding — so you can file on time. If you have more runway, we can extend the same engagement into full catch-up bookkeeping afterward.

Will you disrupt my QuickBooks or Xero while fixing errors?

No. We work directly inside your existing QuickBooks, Xero, NetSuite, or Zoho Books instance. There's no migration, no new software to learn, and no interruption to invoicing, payroll, or reporting while the clean-up is underway.

How do I know the cleaned books are audit-ready for my CPA?

Every entry we correct is tagged, journaled, and backed by source documentation — invoices, bank statements, payroll records — so your CPA or auditor can trace each fix without asking follow-up questions. We deliver a reconciliation support package alongside the trial balance specifically for this handoff.

Can you help if my payroll and AP are months behind?

Yes. This is one of the most common scenarios we handle. We reconstruct missing payroll journal entries from bank records and time-tracking data, reconcile payroll liabilities, and separately clear AP backlogs through three-way matching. Both tracks run in parallel so neither delays your filing.

What if I use an accounting software you don't integrate with?

We integrate with QuickBooks, Xero, NetSuite, SAP, and Zoho Books, which covers the large majority of the businesses we work with. If you're on a different platform, tell us during the free consultation — in many cases we can still work with exports or direct access, and we'll confirm feasibility before you commit to anything.

Do you charge extra for tax-specific fixes like payroll liabilities or year-end cutoff?

No separate line items. Tax-season clean-up work is billed at our standard hourly rate, starting from $7.50 an hour, and payroll liability review and year-end cutoff corrections are part of the core scope of the engagement, not an add-on.
