What Is Absolute Excel IT Filer?
What Is Absolute Excel IT Filer?
The Absolute Excel Income Tax Filer is a standalone Excel-based MTD ITSA bridging software product developed by Absolute Accounting Software Limited — a company with over 30 years of tax and accounting software expertise, trusted by more than 15,000 firms ranging from sole practitioners to multi-office accountancy practices. The product is built on the success of Absolute's Excel VAT Filer, which has been used to submit over 1.1 million VAT returns and accounts for approximately 1 in 20 of all MTD VAT returns submitted in the UK since MTD for VAT became mandatory — a market position that gives the Excel IT Filer considerable institutional credibility among accountants.
The Excel IT Filer uses bridging software technology to link a user's existing Excel spreadsheet directly to HMRC's MTD for Income Tax API. A new Excel template is downloaded quarterly, populated with cumulative income and expense totals, and the data is digitally linked to the relevant HMRC submission boxes via formula before being transmitted. The software requires no lengthy installation and can be set up in minutes. It supports all three MTD income types — sole trader, UK property, and foreign property — and covers the complete end-to-end MTD ITSA workflow including quarterly updates, Business Source Adjustment Summary (BSAS) retrieval and amendment, accounting adjustments (including capital allowances), non-mandated income sources (dividends, interest, CIS, pensions, Gift Aid, student loans, HICBC, and marriage allowance), and the final declaration.

Making Tax Digital Compliance
How the Absolute Excel IT Filer Handles MTD Compliance
The Absolute Excel IT Filer provides a complete end-to-end MTD ITSA workflow from within Excel. A quarterly template is downloaded, populated with cumulative income and expense totals from the user's own records, and the data is digitally linked via formula and transmitted to HMRC. The software covers quarterly updates for sole trader, UK property, and foreign property income; retrieval and amendment of the Business Source Adjustment Summary (BSAS); the annual accounting adjustment process (including capital allowances); filing of non-mandated income sources such as dividends, interest, CIS, pension contributions, Gift Aid, student loans, the High Income Child Benefit Charge, and marriage allowance; and submission of the final declaration. This is a notably more complete end-to-end workflow than most bridging tools offer — many of which cover only quarterly updates and leave the final declaration unsupported or in development. The limitation, as with all bridging tools, is that the user must independently maintain the digital records that the Excel IT Filer transmits.

Bookkeeping, Accounting & Digital Record Keeping
Absolute Excel IT Filer: No Bookkeeping Engine — Excel-Based Record Keeping
The Absolute Excel IT Filer performs no bookkeeping functions. The user's own Excel spreadsheet is their digital record — the Excel IT Filer provides the digital link and submission mechanism. However, the product's design philosophy actively supports this approach: Absolute has long argued that Excel-based record keeping is a perfectly valid, HMRC-confirmed long-term option for MTD compliance, and that accountants and landlords should not feel pressured into adopting expensive full accounting software when bridging software meets HMRC's requirements. The product can link to any existing spreadsheet the user already maintains, requiring minimal change to established workflows.

Invoicing, Expense Tracking
Absolute Excel IT Filer: No Expense Tracking or Invoicing Features
The Absolute Excel IT Filer has no expense tracking, receipt capture, invoice creation, or automation features. All expense recording and categorisation takes place in the user's own Excel spreadsheet before the template is populated and submitted. This is consistent with Absolute's product philosophy: the Excel IT Filer is not positioned as a bookkeeping tool and does not attempt to replicate one. Users who have maintained disciplined Excel records for years can continue doing so unchanged — the IT Filer simply adds the digital submission layer that MTD requires.

Reporting & Tax Forecasting
Absolute Excel IT Filer: No Reporting Features — Records Live in Excel
The Absolute Excel IT Filer produces no financial reports of its own. There is no dashboard, no profit and loss output, and no portfolio overview within the software. However, since users maintain their records in Excel, they retain full control over how they present and report their financial data — and can build or use any Excel-based reporting they choose, independent of the submission tool. For accountants already using other Absolute products or wider accounting software, this division of responsibility is a familiar and deliberate workflow structure.

| Balance Sheet | No |
| Trial Balance | No |

Collaboration & Mobile Apps
Absolute Excel IT Filer: Flexible Workflow Split Between Taxpayer and Accountant
The Absolute Excel IT Filer is specifically designed to allow flexibility in how the MTD process is divided between a taxpayer and their accountant. The taxpayer can complete the quarterly data entry and hand the populated template to their accountant for submission — or the accountant can manage the entire process including all quarterly filings and the final declaration. A Client Portal manages licence allocation, tracks submission history, and supports multiple user access within an accountant's subscription. Phone and unlimited email technical support is available from Absolute's experienced team, reflecting a more human-supported model than many lower-cost bridging tools.

Ease of Use, Support & Security
Absolute Excel IT Filer: Straightforward Excel Workflow with Expert Phone and Email Support
The Absolute Excel IT Filer is designed for users who are comfortable with Excel and want to continue using it for MTD compliance. The setup process takes minutes — download the quarterly template, link it to your existing spreadsheet via formula, and submit. Absolute's testimonials — drawn predominantly from the Excel VAT Filer — consistently praise the simplicity of the process, the quality of the step-by-step guidance in the introductory videos, and the responsiveness of the support team. Crucially, Absolute provides free unlimited technical support via both phone and email — a level of support access that is significantly stronger than most bridging tool competitors, which typically offer email only. The company's 30+ year track record and 15,000+ firm customer base provide a degree of institutional trust that newer platforms cannot yet match. GDPR compliance is stated; the product is HMRC-recognised and meets the regulatory requirements for MTD bridging.

Unique Features Only the Absolute Excel IT Filer Offers
30+ years of tax software expertise and 15,000+ firm customer base
Absolute Accounting Software is one of the most established tax software companies in the UK. Its Excel VAT Filer alone accounts for approximately 1 in 20 UK MTD VAT returns — a market position that validates the technical reliability and HMRC API integration of its bridging products.
Complete end-to-end MTD ITSA workflow in Excel
Quarterly updates, BSAS retrieval and amendment, accounting adjustments including capital allowances, non-mandated income sources (dividends, interest, CIS, pensions, Gift Aid, student loans, HICBC, marriage allowance), and final declaration — all from within Excel. This is a more complete end-to-end coverage than many bridging tools, including several where final declaration support is still in development.
Non-mandated income sources in the final declaration
The Absolute Excel IT Filer supports the filing of dividends, interest, CIS deductions, pension contributions, Gift Aid donations, student loan repayments, High Income Child Benefit Charge, and marriage allowance transfer within the final declaration. This level of coverage goes beyond basic quarterly bridging and makes the product genuinely useful for taxpayers with complex income profiles.
MTD for VAT — proven and market-leading
Absolute's Excel VAT Filer has filed over 1.1 million VAT returns and is trusted by 15,000+ firms. Accountants who already use the VAT Filer can add the ITSA product from the same established provider with confidence. RentalBux does not support MTD for VAT.
Works with any existing Excel spreadsheet — zero workflow disruption
No new bookkeeping system, no data migration, no learning curve. The IT Filer simply links to whatever Excel records the user already maintains. For accountants with established Excel-based client workflows, this is the lowest-friction route to MTD compliance.
NFU partnership and member discount
National Farmers Union members receive a 25% discount (£30 + VAT/year), and Absolute is a recommended provider for NFU members — reflecting the product's relevance to agricultural landlords and rural self-employed individuals who often use Excel-based record keeping.
Free guide to MTD for Income Tax and Bridging Software
Absolute publishes detailed, HMRC-aligned guidance documents (including a free MTD for IT Guide and a Bridging Software Factsheet) that are used by accountants and landlords to understand the regulations — adding educational value beyond the software itself.
Who Should Choose the Absolute Excel IT Filer?
Absolute Excel IT Filer is the best fit for:
Excel users who want the lowest-disruption route to MTD compliance
For landlords and sole traders who have maintained disciplined Excel records for years and want to continue doing so, the Absolute Excel IT Filer adds only the HMRC submission layer without changing anything else.
Accountants managing multiple sole trader and landlord clients on Excel
The per-NI-number pricing model (5 NI numbers for £40 + VAT) is cost-effective for practices with Excel-based client workflows. The flexible split between taxpayer and accountant responsibility is designed for exactly this use case.
Landlords and sole traders who want a fully featured end-to-end MTD workflow from a proven provider
The Absolute Excel IT Filer covers quarterly updates, BSAS retrieval and amendment, capital allowances, non-mandated income sources, and the final declaration — all within a single flat-fee annual licence from a company with 30+ years of tax software expertise.
Users who value phone support from a specialist tax software team
Absolute provides free unlimited phone and email support from an experienced in-house team — a level of support access that few bridging tools at this price point offer.
VAT-registered landlords and sole traders who already use the Excel VAT Filer
Accountants and businesses already using Absolute's VAT Filer can add the ITSA product from the same trusted provider, maintaining a single supplier relationship for all MTD bridging needs.
NFU members and agricultural landlords
The NFU partnership (£30 + VAT/year for members) and Absolute's established presence in the agricultural sector make the Excel IT Filer a natural choice for farming-related property income and self-employment.
Landlords who want complete MTD ITSA coverage including complex year-end income
The ability to include dividends, interest, CIS, pensions, Gift Aid, and other non-mandated income sources in the final declaration makes the Absolute Excel IT Filer suitable for taxpayers with more complex income profiles than simple rental or self-employment income alone.
