DIY Bookkeeping in Germany 2026: What Self-Employed Can Legally Handle Without an Accountant

Wondering whether you can run your own bookkeeping in Germany in 2026 without a tax advisor? Short answer: yes, almost entirely. The longer answer (with the legal limits, a realistic workflow and an honest tool comparison) follows.

In short: DIY bookkeeping in 30 seconds

• Almost everything is allowed. For your own bookkeeping there is no requirement to hire a tax advisor; only commercial tax assistance for third parties is reserved (§ 5 StBerG).
• The EBR is usually enough. Below €800,000 revenue and €80,000 profit, the income surplus calculation suffices; double-entry bookkeeping only applies to GmbH/UG or above those thresholds.
• 30–60 minutes per month. With GoBD-compliant software you handle receipts, banking, VAT return and year-end on a fixed monthly rhythm instead of a year-end scramble.
• Excel is the trap. Plain spreadsheets are not GoBD-compliant; a tax audit can result in your income being estimated. A cheap tool (€60–300/year) removes that risk.
• Tax advisor only for the complex. GmbH formation, a dispute with the tax office or international edge cases. For everything else, software plus occasional hourly advice is the cheaper route.

What self-employed can legally handle themselves

The German Tax Consulting Act (§ 5 StBerG) defines exactly what only registered Steuerberater may do; everything else is open to you. For your own bookkeeping, there is no legal requirement to hire an advisor. The returns just need to be factually correct.

Reserved exclusively for Steuerberater: commercial tax assistance for third parties and representation before the tax court. For your own business, you can take every step yourself. Whether it's worth it depends less on the law than on your time and your case profile; more on that below in When you should still hire a tax advisor.

EBR or double-entry: which do you need?

For most self-employed, the income surplus calculation (EBR) is sufficient. It's a simple comparison of income and expenses: no balance sheet, no inventory. It's allowed as long as:

• Revenue below €800,000 per year
• Profit below €80,000 per year
• No commercial register entry (no GmbH, OHG, KG)

Freelancers (Freiberufler: doctors, designers, consultants) can always use EBR, regardless of revenue. Double-entry bookkeeping, with a balance sheet and profit-and-loss statement, is only required for GmbH/UG or once those thresholds are exceeded. As a sole trader or freelancer, the EBR almost always suffices, and you can run it yourself.

5 steps of monthly DIY bookkeeping

The trick isn't the perfect tool, it's the fixed rhythm. Do your bookkeeping "at some point" and you pile up a backlog; do it once a month and you're through in under an hour.

1. Capture receipts. Every receipt and invoice gets archived digitally. Scanning receipts via app replaces the shoebox approach, and keeps you within the GoBD-standard timely capture of about ten days.

2. Import transactions. Pull bank transactions in weekly. Open-banking integration (PSD2) handles this automatically: no more downloading and retyping statements.

3. Match. Link each transaction to a receipt and assign a category (office supplies, travel, training, marketing). Recurring expenses like rent or phone get booked once as a rule, then apply automatically.

4. File VAT return. Monthly or quarterly via ELSTER. Frequency depends on last year's VAT liability. More on the UStVA.

5. Year-end. Generate the EBR, prepare the income tax return, submit everything through ELSTER. If steps 1–4 run all year, year-end is just a summary, not an all-nighter.

With modern software, steps 1–4 take 30–60 minutes per month. With plain Excel: many times longer, because you type every figure by hand and get no automatic check.

Filing VAT returns yourself: ELSTER vs. software

ELSTER is free but clunky. You enter amounts manually (fields 81, 86, 66, 67 …), sum input VAT correctly, capture discounts separately. One typo or forgotten receipt and you overpay VAT, or invite a query from the tax office.

A modern bookkeeping app like Norman generates the VAT return from your booked receipts and submits it to the tax office directly. Less typing, fewer errors. The return is only ever as good as the receipts behind it, which is why steps 1 to 4 interlock. How to automate the whole chain is covered in automating your bookkeeping.

Excel vs. software vs. tax advisor

Three realistic options for self-employed, with cost, effort and risk side by side:

Excel warning: pure spreadsheets are not GoBD-compliant: receipts must be stored immutably and bookings documented in an audit-proof way. During a tax audit, non-audit-proof records can lead to the office estimating your income upward, and that estimate rarely favours you. Excel alone no longer cuts it in 2026. DATEV alternatives are now plentiful and cheap.

What does DIY bookkeeping really cost?

A tool's price is only half the bill. The real factor is your time. Do the honest math:

• Software: €60–300 a year, plus about 30–60 minutes of work per month.
• Excel: €0 licence, but quickly several hours a month, plus the GoBD risk that gets expensive if you're audited.
• Tax advisor: €1,500–3,000 a year, but almost no work of your own.

If your working hour is worth €50, two extra Excel hours a month cost you €1,200 a year on paper, more than any software, and without the safety. So the cheapest path is rarely the one with no tool, but the one with the right tool: low licence cost, minimal time, no audit risk.

When you should still hire a tax advisor

Clear triggers for external advice:

• Planned GmbH formation or holding structure
• Complex reverse-charge or OSS scenarios with international clients
• Dispute with the tax office (Einspruch, court case)
• First-time switch from Kleinunternehmer to standard VAT with mixed input VAT
• Inheritance or gift tax matters

For everything else, software plus occasional hourly advice is usually better value than a full advisor engagement. Whether your case qualifies is covered in Do I need a tax advisor?.

Common DIY bookkeeping mistakes

Doing it yourself doesn't mean cutting corners. These mistakes cost money or nerves most often:

• Mixing private and business. Without a separate business account you can't keep clean books: the bank feed can't match, and audits get painful.
• Capturing receipts too late. Collect them at year-end and you lose receipts, and with them your input VAT. Capture every receipt right away.
• Forgetting input VAT. Every business expense with stated VAT lowers your liability, but only if the receipt is booked.
• Missing UStVA deadlines. The return is due by the 10th of the following month; late filing triggers surcharges.
• Relying on Excel. The classic: cheap to start, expensive if you're audited. A GoBD-compliant tool is the cheaper insurance.

Frequently asked questions about DIY bookkeeping

Can self-employed do their bookkeeping entirely themselves? Yes, almost fully. Ongoing bookkeeping, EBR, VAT returns and tax declarations for your own business are all yours to handle. Only commercial assistance for third parties and representation before the tax court are reserved for Steuerberater. Your returns simply need to be factually correct.

Do you need a tax advisor as a Kleinunternehmer? No, it's not legally required. Especially as a small business owner with a manageable receipt volume, DIY bookkeeping with a cheap tool is usually the most economical choice. An advisor only pays off for complex cases like a formation or a dispute with the tax office.

Is bookkeeping with Excel allowed? For your own overview, yes; as official books, no. A spreadsheet isn't GoBD-compliant because it can be changed after the fact without a trace. During an audit that can lead to your income being estimated. Use audit-proof software instead of a spreadsheet.

How long does bookkeeping take per month? With GoBD-compliant software, about 30–60 minutes a month for receipts, banking and the VAT return. The condition is the fixed rhythm: once a month, not once a year. With Excel it takes many times longer, because every figure is entered by hand.

May I file the VAT return myself? Yes. You can submit the UStVA to the tax office for free via ELSTER or directly from your bookkeeping software. Software derives the amounts from your bookings automatically and cuts typos, the most common cause of overstated or incorrect returns.

Conclusion

DIY bookkeeping is legal in 2026 and, for many self-employed, the most cost-effective path, provided you use a GoBD-compliant tool instead of Excel hacks and stick to a monthly rhythm. Norman bundles receipt capture, EBR, VAT return and ELSTER submission in one app. That cuts your monthly bookkeeping to about 30 minutes, with automatic VAT filing included. Get started free.
