\n\u2699\ufe0f The modern tax audit<\/b><\/h4>\n
Belgian tax audits have changed. Instead of an inspector showing up with binders and checklists, you\u2019ll often receive digital questionnaires<\/b> with very specific requests.<\/p>\n
The tax administration now uses data mining and algorithms<\/b> to detect irregularities by comparing your VAT returns, income declarations, social data, and even banking information.<\/p>\n
\ud83d\udca1 What this means for you:<\/b><\/p>\n
- \n
- \n
Audits are now more focused and data-driven<\/b>.<\/p>\n<\/li>\n
- \n
You\u2019ll be asked for precise documents or explanations<\/b>, not general overviews.<\/p>\n<\/li>\n
- \n
Keeping your accounting digital, structured, and transparent<\/b> is the best way to stay audit-ready.<\/p>\n<\/li>\n<\/ul>\n
\n1. \ud83d\udce8 Read the audit letter carefully<\/h2>\n
The first thing you should do is understand exactly what the administration is asking for.<\/p>\n
Look for:<\/p>\n
- \n
- \n
The period under review<\/b> (e.g., 2022 income year)<\/p>\n
- \n
- \n
For personal income tax or corporation tax: typically 3 years<\/b> after the tax year; extended to 7 years<\/b> if fraud is suspected.<\/p>\n<\/li>\n
- \n
For VAT: generally 3 years<\/b>, or 7 years<\/b> in case of suspected fraud.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n
- \n
The taxes concerned<\/b>: VAT, personal income tax (imp\u00f4t des personnes physiques \/ personenbelasting<\/i>), or both<\/p>\n<\/li>\n
- \n
The documents requested<\/b><\/p>\n<\/li>\n
- \n
The submission deadline<\/b><\/p>\n<\/li>\n<\/ul>\n
\n\n\n
\n \n \ud83d\udca1 Tip:<\/b> You can upload the audit letter directly in the Documents<\/b> section of Accountable. Our AI assistant will summarise it and tell you which information is required.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
\n\n\n
\n \n \ud83d\udca1 Tip:<\/b> You can also contact the auditor if you need clarification or if you\u2019d like to request an extension,<\/b> this is allowed if you have a valid reason (for example, waiting for your accountant\u2019s availability).<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
\n2. \ud83d\udcc2 Gather the requested documents<\/h2>\n
In Belgium, auditors usually ask for:<\/p>\n
- \n
- \n
Your issued and received invoices<\/b><\/p>\n<\/li>\n
- \n
Proof of payments<\/b> (bank statements)<\/p>\n<\/li>\n
- \n
Expense receipts<\/b> and other supporting documents<\/p>\n<\/li>\n
- \n
VAT returns and the annual client listing<\/b><\/p>\n<\/li>\n
- \n
Income tax returns<\/b> and accounting records<\/p>\n<\/li>\n<\/ul>\n
The auditor is entitled to request all documents necessary to determine your taxable income<\/b> including digital data such as emails or stock lists.<\/p>\n
For VAT audits, bank statements are often checked; however, VAT auditors generally need special authorisation<\/b> to access certain financial information (such as private bank accounts).<\/p>\n
\n
If you use Accountable<\/b>, most of these are already organised for you. Simply go to the related VAT quarter (for instance, Q3 of 2025) \u2192<\/b> go to \u2018Submission\u2019 \u2192 click on \u2018download\u2019 \u2192 select the file-type you want to export.<\/p>\n

<\/div>\n\n
\n3. \ud83d\udd0e Double-check everything (Yes, even triple-check!)<\/h2>\n
Before you send anything, make sure your data is consistent and complete:<\/p>\n
- \n
- \n
Totals in your invoices (excl. VAT if apply) match your declared income<\/p>\n<\/li>\n
- \n
Every expense is backed up by a valid document<\/p>\n<\/li>\n
- \n
VAT is applied and reported correctly<\/p>\n<\/li>\n
- \n
Business and private transactions are clearly separated<\/p>\n<\/li>\n<\/ul>\n
\ud83d\udcd8 Why this matters:<\/b><\/p>\n
Small inconsistencies can trigger additional questions or delays. Showing clean, well-structured data creates trust and helps your audit go smoothly.<\/p>\n
\n
In personal income tax or corporation tax audits, the authorities can correct obvious material errors<\/b> themselves (for example, simple arithmetic or transcription mistakes not interpretation or missing data).<\/p>\n
\n4. \ud83e\udd1d Be transparent and cooperative<\/h2>\n
Auditors from SPF Finances appreciate honesty and professionalism.<\/p>\n
If you made an honest mistake, explain it clearly and provide the corrected figures or documents.<\/p>\n
\n\n\n
\n \n \ud83d\udca1 Tip:<\/b> Keep all communication in writing<\/b> (email is perfectly fine). This ensures you can refer back to it later if needed. Always stay polite and factual.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
\n5. \ud83d\uddc2\ufe0f Stay organised during the audit<\/h2>\n
If the audit happens on-site<\/b> or digitally<\/b>, structure your files by year and category.<\/p>\n
When additional information is requested, provide it promptly.<\/p>\n
\n\n\n
\n \n \ud83d\udca1 Tip:<\/b> For VAT audits, the administration can review up to 3 years back<\/b>, or up to 7 years<\/b> in case of suspected fraud. Keeping a clear archive (even digitally) helps you react fast.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
\n6. \u2705 After the audit<\/h2>\n
Once the audit is completed, the tax administration (SPF Finances \/ FOD Financi\u00ebn<\/i>) may send you different documents depending on the findings.<\/p>\n
\n
Here\u2019s how to understand them \ud83d\udc47<\/p>\n
\n
\ud83e\uddfe If you receive a Statement of Findings<\/b> (Proc\u00e8s-verbal de constatation \/ Verslag van vaststelling<\/i>)<\/h2>\n
This is an official report summarising what the auditor observed<\/b> \u2014 inconsistencies, missing documents, or factual findings.<\/p>\n
It serves as evidence but does not yet change your tax position<\/b>.<\/p>\n
You can:<\/p>\n
- \n
- \n
Review the findings carefully and send explanations or missing documents<\/b><\/p>\n<\/li>\n
- \n
Correct any mistakes voluntarily<\/p>\n<\/li>\n
- \n
Note that the tax office may use this Statement of Findings later to support administrative fines<\/b> (mainly in VAT cases)<\/p>\n<\/li>\n<\/ul>\n
\n\n\n
\n \n The Statement of Findings is not yet a tax adjustment. You don\u2019t need to sign or formally appeal it, but you should respond if something is unclear or inaccurate.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
\n
\u2709\ufe0f If you receive a Proposed Adjustment<\/b> (Proposition de rectification \/ Kennisgeving van wijziging<\/i>)<\/h2>\n
If the administration intends to modify your tax declaration<\/b>, they will send a written proposal explaining why.<\/p>\n
You then have two options:<\/p>\n
- \n
- \n
\u2705 If you agree:<\/b> sign the proposal and pay any additional tax (plus possible late-payment interest).<\/p>\n<\/li>\n
- \n
\u274c If you disagree:<\/b> you can refuse to sign<\/b> and have 30 days<\/b> to respond in writing<\/b> with your explanation or evidence.<\/p>\n<\/li>\n<\/ul>\n
If you don\u2019t respond within that one month, the administration may proceed to an official assessment<\/b> (\u201caanslagbiljet\u201d) based on the information they have. <\/p>\n
If the disagreement continues, the administration may issue a Tax Assessment Notice<\/b> (Avertissement-extrait de r\u00f4le \/ Aanslagbiljet<\/i>).<\/p>\n
From that moment, you have 6 months<\/b> to file an administrative appeal<\/b> (R\u00e9clamation \/ Bezwaar<\/i>).<\/p>\n
You can later go to court if needed, though this is rarely necessary.<\/p>\n
