A client came to us eighteen months behind, dreading corporate tax, and convinced the situation was unusual. It was not. Businesses grow faster than their finance function, bookkeeping slips, and then it slips further because catching up feels overwhelming. The recovery has a sequence, and following it in order makes the whole thing manageable.
Backlog accounting step 1 — establish what exists
Before any bookkeeping happens, we work out what evidence is available. That means bank statements for every account and every period, sales invoices, purchase invoices and expense receipts, existing accounting file if there is one, prior filed returns, and any loan or related-party agreements.
Bank statements are the spine. Almost everything can be reconstructed around them, and they are almost always obtainable even where the paperwork has gone. Missing invoices create difficulty, not impossibility.
This step also produces the fee estimate. Anyone quoting reconstruction without seeing the source material is guessing.
Step 2 — Rebuild the ledgers chronologically
Reconstruction runs forward from the earliest incomplete period, not backwards from today. Each period is posted, reconciled and closed before moving on, because an error in year one propagates through everything after it.
The output for each period is a reconciled bank position, a complete general ledger, a fixed asset register with depreciation, and a trial balance that balances without a suspense account absorbing the difference.
Where genuine gaps remain, they are documented as estimates with the basis stated rather than quietly plugged. That distinction matters enormously if the FTA ever reviews the file.
Step 3 — Correct the VAT position
Reconstructed books almost always reveal VAT that was misstated — output tax omitted, input tax over-claimed, reverse charge missed.
Those errors are corrected through the appropriate route, which depending on size is either a voluntary disclosure or correction in a subsequent return. We covered the mechanics in the voluntary disclosure guide.
Doing this proactively costs materially less than having it found during an assessment.
Step 4 — Bring corporate tax current
With reliable financial statements in place, corporate tax can be computed properly for each affected period — registration regularised if it was missed, elections made where still available, and returns filed.
This is the step that most often produces relief rather than pain. Businesses fearing a large liability frequently find that Small Business Relief applied, or that the profit was smaller than they assumed once expenses were properly captured.
Step 5 — Audit, where required
If your free zone requires audited statements, or a bank or investor has asked for them, the reconstructed accounts go to audit.
Where the same firm did the reconstruction and holds the audit licence, this is substantially faster — there is no second team learning your business from scratch.
Step 6 — Make sure it does not happen again
Reconstruction is wasted money if the same gap opens next year. What prevents recurrence is unglamorous: monthly bookkeeping with bank reconciliation, a chart of accounts built for your actual business, a documented process for capturing expenses, and a compliance calendar with real deadlines.
Monthly bookkeeping costs a fraction of annual reconstruction. That is the entire financial argument, and it holds every time.
What it costs
Reconstruction is priced on transaction volume and the completeness of source documents, not on revenue. A low-volume company with tidy bank statements and most invoices available is a straightforward exercise. A high-volume business with missing records across multiple entities is not.
We scope it first and quote a fixed project fee, so you know the full cost before committing. Open-ended hourly billing on a job of unknown size is how these projects become expensive.
Behind on your books?
We reconstruct backlogged accounts, correct the VAT and tax position, and audit in-house. Fixed fee, scoped up front.
Frequently asked questions
As far back as the underlying evidence allows. Bank statements are usually obtainable for several years, and they form the spine of any reconstruction. Missing invoices make it harder but rarely impossible.
Penalties may apply for late registration, late filing and late payment, and they generally accrue over time. Bringing the position current stops that accrual, which is why acting sooner costs less than waiting.
For a typical SME with two years of backlog, four to eight weeks is a realistic range, depending on transaction volume and how complete the source documents are.
Yes. Reconstruction runs alongside normal operations. What it does affect is licence renewal and any bank or FTA interaction where current financials are requested.
