Preparing Year-End Closing: The Checklist for Freelancers and Self-Employed

The fiscal year is coming to an end - and with it the time when you should get your bookkeeping in order. A well-prepared year-end closing not only saves you time and nerves, but also real money: The better prepared you are, the fewer hours your tax advisor has to invest. In this comprehensive guide, you'll find the complete checklist for your year-end closing as a freelancer or self-employed person - from receipt verification to optimal handover to the tax advisor.

Why Good Year-End Closing Preparation Is So Important

Save Money on Tax Advisor

Tax advisors bill by time. Every minute they spend sorting receipts, following up with you, or correcting errors costs you money. Well-prepared bookkeeping can reduce tax advisor costs by 30-50%.

Calculation example:

• Poorly prepared: 15 hours of work × €120 = €1,800
• Well prepared: 8 hours of work × €120 = €960
• Savings: €840

Use Tax Planning Opportunities

Those who only gather their documents in March of the following year have no time left for tax optimizations. Those who are prepared in December can still:

• Bring forward or postpone investments
• Optimize business expenses
• Plan profit shifts between years
• Use special depreciation

Legal Security and Compliance

A proper year-end closing protects you during tax audits. Complete, chronologically sorted, and traceable documents are the best argument when the tax office comes knocking.

Gain Business Clarity

The year-end closing forces you to reflect on your fiscal year: What went well? Where did you lose money? Which customers were profitable? These insights are gold for the coming year.

The Ultimate Year-End Closing Checklist

Phase 1: Review Open Invoices (November/December)

#### Outgoing Invoices (your invoices to customers)

Analyze open items:

• Create a list of all unpaid invoices
• Sort by age (30/60/90+ days overdue)
• Check which customers regularly pay late

Send reminders:

• First reminder: Friendly reminder (after 14 days overdue)
• Second reminder: Firmer tone, deadline setting (after 30 days)
• Third reminder: Announcement of legal action (after 45-60 days)
• Document all reminders for possible legal steps

Uncollectible receivables:

• Identify receivables that are unlikely to be paid
• Check whether collection or court proceedings make sense
• Prepare write-off (tax deductible!)
• Documentation for tax office (insolvency, unreachability, etc.)

#### Incoming Invoices (invoices to you)

Check completeness:

• Are all invoices for the year recorded?
• Are invoices missing for known expenses?
• Check bank statements for debits without associated invoice

Open liabilities:

• Pay open invoices in the old year (business expense!)
• Or deliberately defer payment to the new year (profit shifting)
• Attention: VAT input tax deduction applies in the month of the invoice

Phase 2: Sort and Digitize Receipts

#### Ensure Completeness

Systematic check:

• Go through each month individually
• Compare receipts with bank statements
• Mark missing receipts

Request missing receipts:

• Request from suppliers and service providers
• For online purchases: Download invoices from customer account
• Set deadline: Receipts must arrive in the old year

Create self-made receipts: For expenses without original receipt (e.g., parking meters, tips):

• Date and time
• Type of expense
• Amount
• Business purpose
• Signature

Note: Self-made receipts should be the exception. The tax office accepts them for plausible small amounts, but not as standard practice.

#### GoBD-Compliant Archiving

The principles for proper management and storage of books, records and documents in electronic form (GoBD) require:

For paper receipts:

• Digitize in readable quality (min. 300 dpi recommended)
• Store immutably (not simple JPG, but audit-proof archive)
• Establish link with booking
• Keep paper original for 6 months after digitization

For digital receipts:

• Store in original format
• No conversion (e.g., email invoice remains as email or PDF)
• Ensure immutable storage
• Document timestamp and origin

Retention periods:

• Invoices and booking documents: 10 years
• Business letters: 6 years
• Period begins at the end of the calendar year

Phase 3: Reconcile Bank Accounts

#### Bank statements complete?

• All months from January to December available?
• Also for secondary accounts (PayPal, Stripe, etc.)?
• Continuous numbering of statements?

#### Assign transactions

• Every account movement assigned to a booking?
• Private withdrawals clearly marked?
• Unclear transactions identified and researched?

Typical problems:

• Regular debits without recognizable purpose
• Transfers to unknown recipients
• Unassignable credits

#### Reconcile cash balance

If you keep a cash register:

• Document cash balance as of December 31
• Compare cash book with actual balance
• Clarify and document differences

Phase 4: Review Fixed Assets

#### What are fixed assets?

Assets that permanently serve the business and have an acquisition value over €800 net:

• Computers and IT equipment
• Office furniture
• Vehicles
• Software (for purchase licenses)
• Machines and tools

#### Calculate depreciation

Straight-line depreciation (standard):

• Acquisition costs ÷ useful life = annual depreciation
• Example: Laptop €2,400 ÷ 3 years = €800 per year

Useful lives (depreciation table):

Low-value assets (GWG):

• Up to €800 net: Immediately fully depreciable
• €250-800: Right to choose between immediate depreciation and regular depreciation
• Since 2024, digital assets like computers are immediately depreciable (regardless of value)

#### Record asset additions

• All purchases of the year in the asset register?
• Acquisition date and costs correct?
• Useful life determined?

#### Document asset disposals

• Sell or dispose of sold or discarded assets
• Record residual book value on sale as profit/loss
• Keep proof of disposal

Phase 5: Provisions and Accruals

#### Form provisions

Tax provisions:

• Estimated income tax and solidarity surcharge
• Trade tax (if subject to trade tax)
• Attention: Consider advance payments!

Vacation provisions (for employees):

• Remaining vacation × daily wage = provision
• Also consider overtime credits

Outstanding invoices:

• Services provided but not yet billed?
• These revenues economically belong to the old year

#### Accruals

Prepaid expenses: Expenses that relate to the new year but were paid in the old year:

• Insurance premiums for January-December, paid in December
• Rent for January, paid in December
• Software annual licenses from January

Deferred income: Income that relates to the new year but was received in the old year:

• Advance payments for projects in the new year
• Maintenance contracts with advance payment

Phase 6: Inventory (if relevant)

If you keep goods (trade, production):

#### Conduct inventory

• Physical count of all goods
• Reference date: December 31 (or max. 10 days before/after with continuation)
• Four-eyes principle for higher accuracy

#### Perform valuation

Valuation methods:

• Acquisition costs (standard case)
• Lower of cost or market principle: If market value has fallen
• Average method for similar goods
• FIFO (First In, First Out) or LIFO (Last In, First Out)

Write-down for:

• Damaged goods
• Obsolete products (fashion, technology)
• Overstocked goods (food, cosmetics)
• Slow movers without demand

Phase 7: Tax Optimization (December)

#### Shape profit

Reduce profit (if too high):

• Bring forward investments (computer, software, office equipment)
• Bring business expenses into the old year
• Perform repairs and maintenance
• Book and pay for training
• Pay business insurance for the following year in advance

Increase profit (if too low):

• Issue invoices faster
• Ask customers for advance payment
• Defer expenses to the new year

#### Use investment deduction (IAB)

• For planned investments in the next 3 years
• Deduct up to 50% of the planned acquisition costs
• Max. €200,000 per year
• Profit decreases, tax burden decreases

#### Optimize business expenses

Check whether you've claimed all business expenses:

• Home office (proportionate rent, utilities)
• Telephone and internet (business portion)
• Travel expenses (€0.30 per km or actual costs)
• Entertainment (70% deductible for business purposes)
• Professional literature and training
• Work clothing (if typical, e.g., protective clothing)
• Account management fees (business account)
• Software and online tools

Typical Mistakes and How to Avoid Them

Mistake 1: Starting too late

Those who only start preparing in February have no time left for optimizations and must frantically gather documents.

Solution: Start at the latest in early December.

Mistake 2: Not sorting receipts chronologically

An unsorted pile of receipts costs the tax advisor (and thus you) a lot of time.

Solution: Sort by date, preferably monthly in folders.

Mistake 3: Mixing private and business expenses

When private and business purchases are on the same receipt, delimitation becomes difficult.

Solution: Strict separation of private and business accounts. If mixed: clearly mark.

Mistake 4: Forgetting digital subscriptions

Software subscriptions, online tools, and streaming services for business are easily overlooked.

Solution: Create a list of all recurring digital payments.

Mistake 5: Not updating depreciation

New acquisitions are forgotten, old assets not written off.

Solution: Maintain your asset register continuously, not just at year-end.

Mistake 6: Not asking questions

Uncertainties are concealed instead of clarified.

Solution: Note questions for the tax advisor throughout the year.
