Key distinction: TaxCalc MTD Quarterly Filer is a spreadsheet bridging solution. Digital records are kept in the user's spreadsheet. Only quarterly summary tottals are submitted to HMRC. The Final Declaration, which replaces teh Self-Assessment return under MTD, is handled by TaxCalc Tax Return Production, a separate product, with its MTD annual submission functionality due for release in Summer 2026. QuickBooks is a fully accounting platform that holds all records, submits quarterly updates, and hyandles the Final Declaration within a single subscription.
Both QuickBooks and TaxCalc MTD Quarterly Filer are HMRC-recognised for Making Tax Digital for Income Tax. Both allow quarterly updates to be submitted directly to HMRC. The resemblance ends there. QuickBooks is a cloud accounting platform designed for businesses and individuals to manage their own bookkeeping and tax submissions. TaxCalc MTD Quarterly Filer is a practice-oriented bridging solution designed primarily for accountancy firms managing clients who keep records in spreadsheets, extending naturally from TaxCalc's established Tax Return Production ecosystem.
This article draws exclusively on each provider's own published pages and HMRC's published guidance, all verified as at July 2026. Prices are stated exclusive of VAT unless noted otherwise.
The MTD for Income Tax Mandate: The Essentials
Making Tax Digital for Income Tax became mandatory on 6 April 2026 for sole traders and landlords with combined qualifying gross income above £50,000 in the 2024 to 2025 tax year. The mandate extends to those with qualifying income above £30,000 from April 2027, and above £20,000 from April 2028.
Qualifying taxpayers must keep digital records, submit four quarterly updates due by 7 August, 7 November, 7 February, and 7 May each year, and file a Final Declaration by 31 January. HMRC has paused penalty points for late quarterly submissions during 2026 to 2027. Financial penalties for late Final Declarations apply from April 2026.
Two distinct obligations: The quarterly updates and the Final Declaration are separate obligations under MTD. Quarterly updates are due four times per year and report income and expenses. The Final Declaration is due by 31 January and replaces the Self Assessment return, calculating the final tax position for the year. Software must cover both obligations for a taxpayer to be fully MTD-compliant.
QuickBooks and MTD
HMRC Recognition and Plan Structure
QuickBooks Online is HMRC-recognised for MTD for VAT and MTD for Income Tax across all five paid UK plans: Sole Trader Plus (£10/month), Simple Start (£16/month), Essentials, Plus, and Advanced. Every paid plan supports the full MTD ITSA workflow including digital records, quarterly updates, and the Final Declaration within a single subscription at no additional product cost.
How QuickBooks Manages Digital Records
QuickBooks holds all digital records within its own cloud platform. Bank feeds via Open Banking pull transactions automatically. AI-powered receipt capture extracts data from photographs. Quarterly updates are generated from these records and submitted directly to HMRC via the API. The Final Declaration is prepared from the same records and filed from within QuickBooks. No spreadsheet is required at any stage.
Income Types and VAT
QuickBooks covers UK property income, self-employment income, and foreign property income within a single subscription. MTD for VAT is available on Simple Start (£16/month) and above. Sole Trader Plus does not include VAT. TaxCalc MTD Quarterly Filer covers UK property and self-employment income for quarterly updates; its VAT Filer is a separate product for MTD for VAT.
Important: QuickBooks requires a separate account for each income source. A landlord who also has self-employment income must maintain two QuickBooks accounts. TaxCalc MTD Quarterly Filer supports multiple sources of income, including multiple businesses or property portfolios, under a single client record.
Practice Tools
QuickBooks Online Accountant provides a centralised multi-client agent-level dashboard for practices filing MTD quarterly updates on behalf of clients. Accountants receive a 50% discount on Sole Trader Plus subscriptions managed through the accountant billing portal. A 30-day free trial is available.
TaxCalc MTD Quarterly Filer and MTD
HMRC Recognition and What It Is
TaxCalc MTD Quarterly Filer is an HMRC-recognised spreadsheet bridging solution produced by Acorah Software Products Limited, trading as TaxCalc, registered at Wokingham (Company No. 03948264). It is available for both individual taxpayers and accountancy practices and is designed to allow continued use of spreadsheets for digital record-keeping while submitting quarterly summaries to HMRC via the MTD API.
How TaxCalc MTD Quarterly Filer works
The TaxCalc Workflow: Step 1: Keep records in any spreadsheet, or use TaxCalc's own free downloadable templates with HMRC income and expense categories pre-populated. Step 2: Import the spreadsheet into TaxCalc MTD Quarterly Filer using the on-screen cell selector and import map. Step 3: Submit quarterly summary tools to HMRC directly from within TaxCalc. Only summary totals are sent to HMRC: individual transactions remain in the user's spreadsheet. Users can also import data from accounting software such as QuickBooks by exporting a profit and loss report to Excel first.
The Final Declaration: A Critical Confirmed Gap as at July 2026

The Final Declaration: A Critical Confirmed Gap as at July 2026
Critical: the Final Declaration tool within TaxCalc Tax Return Production is due for release in Summer 2026. TaxCalc's own Tax Return Production page states: "Support for MTD for ITSA Final Submissions for the 2025/26 Tax Year to be released in Summer 2026." TaxCalc MTD Quarterly Filer handles quarterly updates only. The Final Declaration requires TaxCalc Tax Return Production. As at July 2026, that annual submission functionality within Tax Return Production had not yet been released. Practices and individuals using TaxCalc for MTD quarterly submissions must confirm with TaxCalc directly that the Final Declaration tool is available before the 31 January 2007 deadline.
Income Types and Multi-Source Support
TaxCalc MTD Quarterly Filer supports multiple sources of income under a single client record, including multiple self-employment businesses and multiple property portfolios covering UK and overseas property. Separate quarterly updates are submitted for each income source as required by HMRC, but these are managed from within a single client record rather than requiring multiple accounts. This is a structural advantage over QuickBooks Sole Trader Plus, which requires a separate account per income source.
Calendar Quarter Election
TaxCalc MTD Quarterly Filer supports the calendar quarter election, allowing clients to report to 30 June, 30 September, 31 December, and 31 March rather than HMRC's default tax-year quarters. TaxCalc's own guidance notes this is likely to be the preferred option for most clients. The election must be made before the first quarterly update is submitted.
Practice Integration: The Full TaxCalc Suite
TaxCalc MTD Quarterly Filer is designed to operate either standalone or as part of the wider TaxCalc practice suite. When used alongside the full suite, it integrates with TaxCalc WorkFlow, which can automatically generate the next quarter's update as soon as the current one is completed. TaxCalc Communications Centre can automatically generate client information request emails on a schedule, with reminders. TaxCalc Engager handles client communication and engagement letters. eSign Centre provides digital signatures for approvals. Document Manager stores records. The quarterly submissions then feed naturally into TaxCalc Tax Return Production for the Final Declaration.
QuickBooks has no equivalent integrated workflow automation suite of this kind. Its practice tools are centred on QuickBooks Online Accountant, which provides client management and filing capability but does not include the automated client-chasing, workflow generation, and document management depth of the TaxCalc ecosystem.
Pricing
The individual taxpayer version of TaxCalc MTD Quarterly Filer is available from TaxCalc's individual product pages; pricing is not prominently listed on the main site for individual users and should be confirmed directly with TaxCalc at the time of purchase. The practice version starts at £112 per year for up to 12 clients. Existing TaxCalc customers with an active Tax Return Production Individual and Partnership licence receive a 50% discount. A 14-day free trial of the full TaxCalc practice suite, including MTD Quarterly Filer, is available.
TaxCalc CloudConnect, which enables remote and multi-location cloud access to TaxCalc's desktop software, is an optional add-on. TaxCalc is a desktop application for Windows, Mac, and Linux and is not browser-native in the way QuickBooks is.

Pricing: The Real Comparison for Practices
Individual Taxpayers
QuickBooks Sole Trader Plus at £120 per year covers the full MTD ITSA workflow including the Final Declaration within one subscription. TaxCalc's individual MTD Quarterly Filer pricing should be confirmed directly with TaxCalc, as it was not prominently listed on published individual product pages at the time of writing. TaxCalc Tax Return Production for individuals would be required as an additional product for the Final Declaration. For an individual who does not already hold a TaxCalc Tax Return Production licence, the combined cost of both TaxCalc products will narrow or eliminate any apparent pricing advantage over QuickBooks.
Accountancy Practices
TaxCalc MTD Quarterly Filer at £112 per year for up to 12 clients (£9.33 per client per year) is substantially cheaper per client than managing 12 clients through QuickBooks Online Accountant at approximately £10 per client per month (£1,440 per year for 12 clients at Sole Trader Plus rates), though the QuickBooks price covers a full accounting platform, not just the quarterly submission step. Practices with existing TaxCalc Tax Return Production licences receive a 50% discount on MTD Quarterly Filer, making it an even lower incremental cost. For practices that are already TaxCalc-centric, adding MTD Quarterly Filer is the most cost-efficient and workflow-consistent route to quarterly MTD compliance.
Which Is Right for Your Client?
Choose QuickBooks If Your Client or Practice:
Needs a single, complete MTD solution covering digital records, quarterly updates, and the Final Declaration without purchasing multiple products.
Does not currently keep structured digital records and needs bank feeds and AI receipt capture to automate bookkeeping.
Is VAT-registered and needs MTD for VAT and MTD for Income Tax from one integrated subscription.
Is managed by an accountancy practice using QuickBooks Online Accountant for centralised, cloud-based client management and agent-level MTD filing.
Prefers a cloud-native, mobile-accessible platform with no desktop installation required.
Choose TaxCalc MTD Quarterly Filer If Your Practice:
Already uses TaxCalc Tax Return Production and wants to add quarterly MTD submissions as a natural, integrated extension of the existing workflow, at a 50% discounted rate.
Has a client base with established spreadsheet habits and wants to manage MTD compliance for those clients without migrating them to cloud accounting software.
Needs the WorkFlow, Communications Centre, eSign, and Document Manager integration to automate client-chasing, approval, and filing across a large portfolio of MTD clients efficiently.
Manages clients with multiple income streams, including multiple property portfolios, and needs those handled under a single client record rather than multiple accounts.
Has confirmed directly with TaxCalc that the Final Declaration tool within Tax Return Production is released and available for the relevant tax year before advising clients to rely on the TaxCalc route for year-end compliance.
What Neither Platform Fully Resolves
Partnerships are not yet in scope for MTD for Income Tax. HMRC has not confirmed a start date. Both platforms cover individual taxpayers only for MTD ITSA.
MTD for Corporation Tax is not yet mandated. Limited company landlords are outside the scope of MTD ITSA.
The Final Declaration covers qualifying business income but does not replace the need to declare employment income, dividends, or capital gains separately.
Neither platform confirms automated Section 24 mortgage interest tax credit calculations within their standard MTD quarterly update workflows.
HMRC has paused penalty points for late quarterly submissions during 2026 to 2027. Financial penalties for late Final Declarations apply from April 2026. Practices using TaxCalc must confirm the Final Declaration tool is available well before the 31 January 2027 deadline.
Conclusion
QuickBooks and TaxCalc MTD Quarterly Filer serve different purposes and are most naturally compared in the context of a practice decision rather than an individual one.
For individual sole traders and landlords who want a single, complete MTD solution covering digital records, quarterly updates, and the Final Declaration in one subscription, QuickBooks is the more straightforward choice today. Its full-platform design removes the need to purchase, integrate, or maintain separate products for different parts of the MTD workflow.
For accountancy practices that are already TaxCalc-centric, the addition of TaxCalc MTD Quarterly Filer is the most natural, cost-efficient, and workflow-consistent route to quarterly MTD compliance for spreadsheet-based clients. The deep integration with WorkFlow, Communications Centre, Engager, eSign, and Document Manager provides a level of practice automation that QuickBooks Online Accountant does not replicate. The 50% discount for existing Tax Return Production customers makes the incremental cost modest.
The most important practical note for both groups remains the Final Declaration. QuickBooks covers it within every paid plan. TaxCalc's Final Declaration functionality within Tax Return Production is confirmed as due for release in Summer 2026; any practice or individual relying on TaxCalc for the full MTD annual workflow must confirm that release with TaxCalc directly before the 31 January 2027 deadline.
