Recurring clientsBased on 4,247 filings. These are the most common post-filing queries from HMRC.
| Query Type | Frequency | Why HMRC Asks | Our Response |
|---|---|---|---|
| Capital Allowances Claim | 24% | Large capital allowances claim (particularly Annual Investment Allowance £1m). HMRC checks asset purchases qualify (plant/machinery, not buildings). | Provide: Asset register, invoices, AIA calculation workings. Response time: 2-3 days |
| Loss Carry-Forward | 18% | Prior year losses claimed. HMRC verifies loss originated in correct period and was unused (not already offset or surrendered to group). | Provide: Prior year CT600, loss memorandum, confirmation no group relief claimed. Response: 1-2 days |
| Disallowable Expenses | 16% | Tax computation adds back expenses (entertaining, depreciation). HMRC checks calculation correct and no taxable items omitted. | Provide: Expense breakdown, add-back calculation, trial balance extract. Response: 1-2 days |
| Related Party Transactions | 14% | Transactions with directors/shareholders/group companies. HMRC checks arm's length pricing (transfer pricing rules for groups >£3m profit). | Provide: Loan agreements, management charge invoices, transfer pricing documentation. Response: 3-5 days |
| Prior Year Adjustments | 12% | Current year accounts include prior year adjustment (error correction/policy change). HMRC checks if adjustment affects prior CT600. | Provide: Prior year accounts comparison, adjustment explanation, amended CT600 if tax affected. Response: 2-4 days |
| R&D Tax Relief Claim | 9% | R&D tax credit claimed (SME scheme or RDEC). HMRC checks qualifying expenditure (staff costs, materials, subcontractors). May request project details. | Provide: R&D report, staff timesheets, project descriptions, technical explanations. Response: 5-7 days (complex) |
| Deferred Tax Calculation | 5% | Deferred tax provision in accounts (timing differences). HMRC checks consistency with capital allowances and tax losses disclosed. | Provide: Deferred tax working paper, reconciliation to tax computation. Response: 1-2 days |
| Foreign Income/Branches | 2% | Foreign branch/overseas income disclosed. HMRC checks double tax relief claimed correctly and foreign tax paid evidenced. | Provide: Foreign tax computations, double tax relief calculation, foreign tax payment proof. Response: 5-7 days |
94% of queries resolved without adjustment. In 6% of cases, HMRC finds issue requiring amended CT600 (e.g., capital allowances overstated, loss claim incorrect). If amendment needed, we prepare corrected CT600 and negotiate with HMRC. Average outcome: £500-£2,000 additional tax (settled within 30 days, no penalties if reasonable care taken). Our post-filing support covers query handling—amendment preparation charged separately (£300-£800 depending on complexity).
0.4% of filings bounced back after initial acceptance. Here's why and how we fix them.
XBRL tagged values don't balance (assets ≠ liabilities + equity). Usually rounding issue (£000 vs £). CH automated check catches this post-acceptance.
38% of bounce-backsFix time: 2-4 hours (adjust XBRL rounding, refile)
Accounting period dates in XBRL context don't match company's year-end on CH records. Example: XBRL says 31/12/2024, CH expects 31/03/2024.
24% of bounce-backsFix time: 1-2 hours (update context dates, refile)
XBRL calculation linkbase validation fails. Sub-items don't add to parent total (e.g., current assets + non-current assets ≠ total assets). Taxonomy-specific issue.
18% of bounce-backsFix time: 3-5 hours (review calculation tree, fix tags)
CH system detects accounts for same period already on file (e.g., client filed manually before engaging us). CH rejects to prevent duplicate public record.
12% of bounce-backsFix time: 24 hours (liaise with CH, supersede old filing)
Wrong taxonomy version used (e.g., old FRS 102 taxonomy for current year filing). CH requires latest published taxonomy for each period.
8% of bounce-backsFix time: 4-6 hours (re-tag with correct taxonomy)
If bounce-back is our fault (tagging error, validation failure), we fix and refile within 24 hours—included in original fixed price. We also cover any late filing penalties up to £500 if delay causes deadline miss (rare—we prioritize bounce-back fixes urgently). If bounce-back is due to client data issue (you gave us wrong figures, balance sheet doesn't balance in source accounts), we still fix and refile under unlimited revisions policy (no extra charge—you provide corrected accounts, we re-tag). 0.4% bounce-back rate vs industry average 1.2%—our validation process catches most issues pre-submission.
After first filing, you become recurring client. Enjoy benefits for next year's filing.
Automatic 15% discount on next year's fixed price. Example: First year £850 → Next year £722. Applied automatically when you return (no need to request). Multi-year discount increases: Year 3+ = 20% off, Year 5+ = 25% off. Loyalty rewarded.
We retain prior year XBRL tags, taxonomy mapping, entity-specific extensions. Next year: Copy forward prior year structure → update figures → validate comparatives → done. Saves 30-40% tagging time. Faster turnaround: 3-5 days vs 5-7 days for new clients. Prior year comparatives auto-populated from our archive.
Recurring clients jump the queue. Peak season (December-March): New clients wait 5-7 days. Recurring clients: 2-3 days. Dedicated account manager remembers your preferences (abridged vs full accounts, NOMAD approval required, etc.). No need to re-explain company structure each year.
We track your next filing deadline (12 months after accounts period end + 9 months grace). Calendar reminders sent: 90 days before deadline, 60 days before (start preparing accounts), 30 days before (urgent—accounts finalized?), 14 days before (last call). Portal shows countdown timer. SMS reminders available on request.
Still covered—12-month support means any query received within 12 months of filing date. Even if query arrives on day 364 and takes 30 days to resolve (crossing into month 13), we handle it at no charge. Support period refers to when issue arises, not when it's closed. Rare edge case: HMRC opens compliance check in month 11, takes 6 months to complete (into month 17). First 10 hours free (included), then hourly rate applies (£150/hour) for work beyond 10 hours. But this affects <0.1% of clients.
Both. We handle HMRC phone queries if you forward call to us (you give HMRC our number, we act as your agent). Requires HMRC 64-8 form (agent authorization)—we prepare this for you at filing stage (included). Written queries: We draft responses, you review and approve. Phone queries: We speak to HMRC directly, then update you on outcome. Some clients prefer to take HMRC calls themselves (they understand business better)—we prepare talking points and follow up in writing. Your choice—we're flexible.
Support ends 12 months after filing date (not accounting period end). Example: Filed 1 Dec 2024 for 31 Dec 2023 accounts → Support ends 1 Dec 2025. If you file next year's accounts (31 Dec 2024) on 1 Nov 2025, new 12-month support starts 1 Nov 2025—overlaps with prior year support by 1 month (both covered). If you don't file next year by 1 Dec 2025, prior year support expires. Gap year scenario (you delay filing next year): Hourly rate applies for any post-12-month queries (£150/hour). But this is rare—most companies file annually on schedule.
Yes, but charged separately (not included in free 12-month support—that only applies to filings we prepared). Fee: £300-£800 depending on complexity. Process: You provide copy of prior year iXBRL file + HMRC query letter. We review filing, draft response, submit to HMRC. Common scenario: Previous provider went bust or doesn't respond to queries. We step in and handle retrospectively. If you switch to us for current year filing, we include prior year query handling as goodwill gesture (first query free, builds relationship). Ongoing queries charged at £150/hour after first query.
