Handing receipts to your tax advisor: how to make it faster and cheaper
Handing receipts to your tax advisor the right way: which documents the firm needs, the format that saves time, and how to avoid the queries and billable hours.
In short: Your tax advisor works fastest when they receive complete, legible receipts as PDFs, sorted chronologically, with date, merchant and amount in the file name and a list to go with them. Every query, every faded receipt and every loose paper bag costs firm time that you pay for. Scan monthly and do one clean handover a year, and you save hours on the bill.
A tax advisor's bill in Germany has two parts: the fee under the Steuerberatervergütungsverordnung (the statutory fee schedule) and the time spent on everything the firm has to sort, decipher or ask about first. You can hardly influence the first part. The second part you can, and considerably. A box of paper receipts, a few photos on WhatsApp and three rounds of questions in February are the most expensive route.
This article shows which documents your Steuerberater (the German term for a tax advisor) really needs, in which format to hand them over, how to sort them and which mistakes push the bill up.
Which documents does the tax advisor really need?
For the bookkeeping and tax return of a small business the firm needs five groups of documents: outgoing invoices, incoming invoices and receipts, bank statements, cash records (if you handle cash) and contracts with tax relevance. Everything else is padding.
A checklist for the handover:
- All outgoing invoices for the period, numbered without gaps
- All incoming invoices and till receipts, each one legible and complete
- Bank statements for all business accounts, including PayPal or credit card, as PDF
- Cash book, if you take cash
- New or changed contracts: rent, leasing, loans, insurance
- Mileage log or a list of business trips with receipts
- Self-made receipts (Eigenbelege) for missing receipts, with a reason
- Open questions collected on one sheet instead of twelve emails
Receipts that match no payment, and payments that match no receipt, are the main source of queries. Reconcile your bank statements with your receipts before the handover. Whatever is missing is easier to find now than in a conversation with the firm. A similar checklist from the Swiss perspective is in Preparing receipts for your accountant.
In which format should you hand documents to your tax advisor digitally?
As PDF, one receipt per file, with a descriptive file name, in one folder per month. That is the format every firm can process without explanation. PDFs can be imported into DATEV Unternehmen online, Lexoffice, sevDesk or any document management system and matched to the booking there.
A good file name contains date, merchant and amount, for example "2026-03-14 Bauhaus 118.90.pdf". The firm can already see what the file contains in the file list and sort by date. With Belego this format is created automatically: the app saves every scan as a PDF, reads date, merchant and amount and names the file accordingly on export. The ZIP export for a year or a month contains all PDFs, a CSV list with category and note, and a short README. That ZIP file is the entire handover.
What to avoid:
- Photos as JPG via messenger: not an archive format, often compressed and blurry.
- One single PDF with 300 pages: the firm has to split it, which costs time.
- Receipts pasted as images into a spreadsheet: cannot be imported.
- Paper and digital mixed for the same period: the firm has to reconcile both.
Why PDF rather than JPG is the standard and what a folder structure with clear file names looks like are explained in two separate articles.
How should you sort receipts for your tax advisor?
Chronologically, by month, and within the month by date. Not by category. The firm books along the bank statements, and those are chronological. A receipt from 14 March is needed when the debit of 14 March is booked. Sorting by "office supplies" or "travel" helps you get an overview, but not the bookkeeper.
Categories still add value when they appear as a column in a list. The CSV from Belego contains date, merchant, amount, currency, category and note for each receipt. The firm can open the list in Excel or the accounting software and filter by category when checking account assignments. Which columns such a list needs is covered in Exporting receipts as CSV.
The note is the underrated part. "Client meeting Weber, trip to Cologne" on the fuel receipt or "Hospitality project X, 3 people" on the restaurant bill answers the question the firm would otherwise have to ask. Two seconds when capturing save an email in February.
Which mistakes make the tax advisor's bill more expensive?
The most expensive mistake is incompleteness, followed by illegibility and lateness. Every missing receipt triggers a query, and every query is billed by time.
| Mistake | Consequence at the firm | How to avoid it |
|---|---|---|
| Receipt missing | Query, late booking, possibly no VAT deduction | Reconcile monthly with bank statement |
| Receipt faded | Unusable, self-made receipt needed | Scan thermal receipts on the day of purchase |
| Everything in January at once | Waiting time, peak-season surcharges | Deliver quarterly or monthly |
| Private and business mixed | Sorting work, queries | Hand over business receipts only |
An example with realistic figures: a firm charges 120 euros per hour for bookkeeping work. Two hours sorting a box of paper, one hour for ten queries by email and half an hour scanning receipts add up to 420 euros that do not arise with a clean ZIP handover. That is more than the annual price of any receipt app and more than the time you need yourself.
Then there is the paper question: if you scan and throw away the original, the scan has to meet the GoBD requirements. What that involves is explained in GoBD and replacement scanning. Many firms provide a template process document for this; ask for it.
Monthly or yearly: when should you hand over receipts?
Monthly if you are registered for VAT and file advance returns; otherwise at least quarterly. The firm needs the receipts for the advance VAT return by the 10th of the following month anyway. If you deliver them by then, the annual bookkeeping gets done as a by-product, and only the annual accounts remain for January.
A realistic rhythm: scan receipts on the day of purchase, spend ten minutes at the end of the month checking (anything missing, every amount correct, notes in place), then export and upload to the firm's portal or send by email. For the year-end handover all that is left is a short check, as described in Year-end receipts: ready in three steps.

Frequently asked questions
Do I have to give my tax advisor the original paper receipts?
No. Most firms now work digitally and prefer PDFs they can match directly in the accounting system. The retention obligation stays with you: you must keep the receipts for eight years, on paper or as a GoBD-compliant scan. The tax advisor archives the bookkeeping, not your receipts. Check with the firm whether they still accept paper at all.
Can I just email receipts to my tax advisor?
Technically yes, in practice only in bundles. Twelve emails with one photo each are more work for the firm than one ZIP file per month. Many firms offer a portal or an upload folder; use it if there is one. Mind the size too: a year of receipts as PDFs usually fits comfortably into one email or upload.
What happens to receipts the tax advisor cannot match?
They ask, or they book the item to a suspense account until the question is resolved. Both cost time. In the end an unresolved receipt either goes without a deduction or is booked as a private withdrawal. A note with the occasion and context at the time of capture prevents this in almost every case.
If I switch tax advisors, what do I take with me?
The previous tax advisor must hand over your documents, including the bookkeeping data and annual accounts. Your own receipts as a PDF archive come with you anyway if you scanned them yourself. That is one more reason to keep the receipts in your own hands instead of only storing them at the firm.
