A tax provision is not a number — it is a binder of judgments that auditors and examiners will open later. Pick a tab and see how we build each one. The questions are illustrative examples of what auditors and examiners ask; the workproducts are the services themselves. No figures, no advice — just the shape of the work.
“Show us the path from book income to the provision. Where does every temporary difference live — and does each deferred balance tie back to a filed position?”
Illustrative example — a typical auditor / examiner askCurrent and deferred taxes under ASC 740 (FAS 109), computed from your records and tied to the positions you actually filed — the computation, the support for every material difference, and a package your auditors can follow without a scavenger hunt.
Income Tax Accounting · Tax Provision Preparation & Review“What evidence supports the valuation allowance conclusion — and where is the negative evidence weighed, not just the positive?”
Illustrative example — a typical auditor / examiner askThe realizability analysis for your deferred tax assets is assembled and documented as part of the ASC 740 provision itself — the evidence on both sides, weighed in the open, so the conclusion reads as a judgment that was made, not a number that appeared.
Income Tax Accounting (ASC 740 / FAS 109) · Provision Preparation & Review“For each uncertain position: what is the unit of account, what is the measurement — and where is the file that defends it?”
Illustrative example — a typical auditor / examiner askEvery material uncertain tax position identified, analyzed, and documented under FIN 48 — written to be read by an auditor this quarter and an examiner three years from now, in the same condition.
FIN 48 Uncertain-Tax-Position Analyses & Documentation“Your effective rate moved. Which drivers are permanent, which are one-time — and can you prove the bridge?”
Illustrative example — a typical auditor / examiner askThe reconciliation is built inside the same provision file as the computation — every driver tied to its support, no orphan numbers, no unexplained plugs between the statutory rate and your effective rate.
Income Tax Accounting (ASC 740 / FAS 109) · Provision Preparation & Review“You had an ownership change. What is the annual limitation on your tax attributes — and where is the study?”
Illustrative example — a typical auditor / examiner askThe testing-period analysis and the limitation computation, documented as a standalone study — so the attributes on your balance sheet are attributes with a file behind them, with examination support if the study is ever challenged.
Section 382 Ownership-Change & Attribute-Limitation Studies · Examination SupportYour provision is already a file — the only question is whether it reads like one.

“The technical rigor of a large firm, with the personal attention of a boutique practice.”
That is the trade every growing company is offered: a department too big to know your file, or a generalist too small for your provision. We are the third option — a senior team that treats your tax function as its own.
Start the ConversationNeil D. Bass founded the practice in 2006 as SmarTax — leveraging his background as a Big Four auditor, he developed a concept that has evolved into the trusted Bass Tax Group. Since 2006, the firm has been proudly owned and led by former Big 4 corporate tax professionals, dedicated to delivering excellence every day.
Twenty years on, the model has not changed: a small, senior team, collaborating with your people year after year, quarter after quarter — so the provision, the positions, and the filings are one continuous file, not four disconnected events.
We collaborate seamlessly with your team, year after year, quarter after quarter. Your file is known — not re-learned every season.
We’re here for you whenever you need us — the same senior professionals who built your workpapers are the ones who answer for them.
