KPiR (Record of Income and Costs) is a simplified tax accounting method for sole proprietors. But not all business expenses are tax-deductible. Understanding which expenses you CANNOT deduct helps avoid audit issues and penalties. This guide lists the most common non-deductible expenses.

Personal and Household Expenses

Expenses that mix personal and business use cannot be deducted, or only partially:

  • Rent and utilities (home office): Only the business-use portion is deductible. If you use 25% of your apartment for business, you can deduct 25% of rent
  • Groceries and food: Personal meals are never deductible. Business meals may be deductible with proper documentation
  • Personal care: Haircuts, cosmetics, gym memberships – all non-deductible
  • Family member salaries: Only deductible if the person performs actual work and is properly documented in payroll

Fines and Penalties

Legal consequences of business violations are not deductible:

  • Traffic fines
  • Tax penalties and interest
  • ZUS contribution arrears penalties
  • Late payment penalties to suppliers
  • Court-ordered penalties

Rule of thumb: If you're fined for breaking a law, it's not deductible.

VAT on Personal Goods

VAT is only deductible on business purchases. VAT on non-business items cannot be deducted:

  • Luxury goods (cars over certain value, yachts, private aircraft)
  • Fuel for personal vehicle use
  • Private accommodation and meals
  • Entertainment and leisure activities

If you buy supplies for resale but use some personally, only business-use percentage is deductible.

Entertainment and Hospitality Expenses

Business entertainment expenses are strictly limited:

  • Client entertainment: Deductible with proper business justification and documentation
  • Employee entertainment: Christmas parties and team events partially deductible
  • Unnecessary entertainment: Theater tickets, sporting events for personal enjoyment – not deductible

Key requirement: Must be necessary for business operations and properly documented.

Personal Development Without Business Connection

Training and education expenses must be business-related:

  • Industry certification courses: Deductible (e.g., accountant's professional course)
  • Language courses: Deductible if needed for business
  • Academic degrees unrelated to business: Not deductible
  • Personal hobby training: Not deductible

Insurance Premiums - Restricted

Some insurance premiums are limited or non-deductible:

  • Business liability insurance: Fully deductible
  • Vehicle insurance (business use): Only business-use portion deductible
  • Personal life insurance: Not deductible
  • Health insurance (if required to pay separately): Only if properly documented as business expense

Corporate Gifts and Sponsorships

Gift expenses have strict rules:

  • Small gifts to clients: Deductible up to certain value limits (usually €50-100)
  • Employee bonuses and gifts: Deductible only if documented in salary records
  • Sponsorships: Only deductible if directly promoting business (marketing)
  • Charitable donations: Special rules apply; not treated as normal business expense

Asset Depreciation Issues

Not all asset purchases can be immediately deducted:

  • Capital assets: Must be depreciated over years (office equipment, vehicles, real estate)
  • Small assets (under €200): Can be expensed immediately
  • Personal-use assets: Cannot be depreciated at all
  • Mixed-use assets: Only business-use portion depreciable

Loan Losses and Bad Debts

Personal loans to friends and family are not deductible:

  • Personal loans given to non-customers: Not deductible if uncollected
  • Bad debts from customers: Can be deductible with proper documentation
  • Loans to family members: Must be formal business loans with written agreements
