Hand your accountant a clean file for the period, with the gaps already marked.

Tax return data assembles what your accountant needs for a period. Sales are grouped the way your tax returns ask, alongside the purchase register with supplier tax registration numbers, credit notes and an item code summary. Problems in your data show before the file leaves your office. Your accountant confirms the local treatment, and we record that decision against the setting. The software prepares data and gives no tax or legal advice.

What it is

On the eighth the accountant asks for last month’s sales file. What arrives is an export with three customers missing a tax registration number, two bills raised with the wrong place of supply, and a credit note nobody mentioned. The next four days go on corrections by email.

The data is assembled from bills as they were raised, period by period. Anything a return would reject shows up first on your side. Fix it here. Then the file goes across clean.

What it replaces

What your team uses today.

The module takes over these, one at a time, so nothing has to stop while it is set up.

  • A sheet pieced together at period end
  • A pile of purchase bills checked by hand
  • A note of items to correct next time
Where it goes wrong today

The problems this is meant to ease.

Returns assembled in a rush

Sales are totalled in the final days of the period. Errors found then are fixed under pressure.

Supplier details missing

Purchase bills arrive without a tax registration number. The gap is found while the return is open.

Credit notes detached

A credit note exists but is not tied to the bill it corrects. The return shows both. Nobody can reconcile them.

Mismatch found after filing

The authority statement differs from your register. The difference is noticed when it is costly to fix.

Filed periods change quietly

An old bill is edited after filing. The return and the books no longer agree.

Inside the module

What tax return data does.

Sales, grouped as the return asks

Business sales, counter sales, exports and credit notes, grouped for the period your accountant is preparing, in the way your own tax rules require.

Purchase register with registration numbers

Supplier bills for the period with their tax registration numbers, tax split and bill dates. This is the half that is usually missing.

Checks before it goes out

A missing registration number, a wrong place of supply, an item with no classification code. Each is listed with the bill it sits on.

Item code summary

Quantity and value by item classification code for the period, worked out from the item master and not typed into a sheet.

Compared against the authority statement

Your purchase register is set beside any statement your accountant downloads from the tax authority, so bills a supplier never reported are visible early.

A period locked once filed

After the return goes, that month cannot be quietly edited. Changes become amendments, which is what your accountant needs them to be.

Where it gets used

What this looks like in a working week.

Illustrative scenarios, written to show the shape of the work. They are not accounts of client systems.

Period close

The accounts assistant runs the checks for the period. Missing registration numbers appear on a list. So do unmatched notes.

Credit note against a bill

Returned goods lead to a credit note. It links to its bill and appears under the proper heading in the data.

Compare with the statement

The accountant loads the authority statement. Lines that differ from the purchase register are listed, with a note on each.

After filing

The accountant locks the period. A later correction goes in as an amendment, visibly.

Who touches it

The people who open this every day.

Accounts assistant

Clears the check list, exports the period and answers one email and not nine.

Your accountant

Receives a file that opens in the filing software already in use, with the differences already marked.

Owner

Learns which suppliers never upload their bills. That is money and not paperwork.

How it is set up

From first conversation to daily use.

  1. Review the returns you file

    Share a past return and the register behind it. A note follows. It names the groupings the data must follow.

  2. Confirm treatment with your accountant

    How local rules apply to your items is decided by the accountant. Each decision is recorded against its setting. The software prepares data and gives no tax advice.

  3. Trial on a past period

    Provide the bills of a closed period. A trial output comes back with the check list, to hold against the filed return.

  4. Train accounts

    Accounts staff and the accountant rehearse the checks on real bills. Written answers follow any questions.

  5. First live period

    Data for the period is prepared and the accountant files from it. The period locks after filing.

Measuring it

How you would know it is working.

Record where you stand before it goes live, so the change is measured against your own figures.

  • Bills missing a supplier registration number
  • Credit and debit notes not linked to a bill
  • Mismatch lines still open against the authority statement
  • Periods locked after filing
  • Amendments made after a period was locked
How it fits

It is one part of a system, not an island.

A module earns its place by what it passes to the next one. These are the connections we set up most often.

  • Invoice management
  • Tax management
  • E-invoicing where a tax authority requires it
  • Your accountant’s filing software
  • Accounting software
Common questions

Questions owners ask about tax return data.

Does it file our tax returns?

No, and be careful with software that says it does. It prepares the data for a period. Filing happens in your accountant’s software or on the authority’s system, and nothing is filed without your approval. Responsibility for what is filed stays with your business and your accountant.

Can it match our input tax credit?

It can compare your purchase register with any statement your accountant downloads, and show what is missing on either side. Whether a credit may be claimed is your accountant’s call.

Is this needed if our accountant works straight from accounting software?

Then leave it alone. This is for businesses billing at a counter or a site, where bills reach the books late and corrections happen over email early every month. Share how your bills reach your accountant today and we will say whether this is worth building.

What if a bill has to change after the return is filed?

The period is locked, so the change is recorded as an amendment with its own date and reason. How it is reported afterwards is decided by your accountant and not by the software.

What changes the quote for tax return data?

The volume of bills raised, the invoicing and accounting systems linked, and any e-invoicing need. Each connection is separate work. Your scope is read first, and any connection can be taken out of the quotation.

What decides when the first period can be prepared?

The completeness of item codes and supplier details, plus the date your accountant confirms treatment. Sales grouping, the purchase register and the checks make the opening release. Statement comparison follows. The proposal holds dates.
