The game changed in 2026. Four new rules you need to know.

Before the mistakes, the context. As of January 1, 2026, six laws of the fiscal package will be in effect, and four of them directly affect how you file.

First, physical cash was strictly limited. Business-to-business payments over 100,000 lek must now pass exclusively through the bank, down from the old limit of 150,000 lek, and sales over 500,000 lek to individuals cannot be paid in cash. Second, the time to correct errors was shortened. The amended declaration must be filed within 24 months, down from the previous 36, and the annual personal return must be corrected within six months, up to a maximum of two times. Third, the POS terminal becomes mandatory by May 30, 2026 for tourism and transportation and by December 31, 2026 for others. Fourth, automatic fines: the e-Filing system issues them itself once the deadline passes, without waiting for an inspection.

There are also two relief measures worth knowing about. Old obligations are conditionally forgiven until December 31, 2026, as covered in the final section, and sales and purchase books must now be submitted by the 11th of the following month, one day later than the old rule of the 10th. All the updated rules are available on our website. tax legislation.

Ten mistakes, from the most serious to the least serious

1. Lower pay on paper than in hand

The most common and most costly mistake. The employee receives the actual salary, the payroll records a lower amount, and the difference is paid in cash. Hiding wages is punishable by up to 2001 TP3T in fines under Article 119 of Law No. 9920, plus unpaid contributions backdated. The employee bears the second loss, with pension and credit calculated on the fictitious wage.

How does the audit find it? By comparing salaries with the sector market, by employees' bank transactions, and by the loan declarations themselves. And with the new cash limits, the difference in hand becomes increasingly traceable. The avoidance is simple: a real salary on the payroll, with costs calculated in the job offer itself. Pay calculator.

2. Employee working without being declared

Summer seasonal, trial waiter, weekend assistant. The fine is 200,000 lekë per person for VAT and profit taxpayers under Article 119, and the on-site inspection confirms it with a simple question: who is working here today. Evasion: every employee must be declared before starting work, even for a one-day trial, with a contract according to Labor Code and with Statement of personal status in the folder.

3. Sales without an invoice and hidden revenue

A portion of sales goes without an invoice, and the declared revenue is lower than the actual amount. Tax evasion is punishable by a 100% penalty on the difference under Article 116, failure to issue an invoice by 25,000 to 75,000 lek under Article 123, and on recurrence by up to 500,000 lek with a 30-day business suspension. This also includes income from clients abroad, which often goes completely undeclared.

How the tax authority finds it. The tax system sees invoices in real time, the bank sees the incoming funds, and with POS made mandatory as of the end of 2026, the cash register also becomes readable. Evasion, every sale by invoice through fiscalization system, no exceptions for VIP clients.

4. Rent paid without withholding

The business rents the premises from an individual, pays the rent, and does not withhold 15% tax at source. This is the most common finding in audits, because it is revealed by the lease agreement itself, and the unpaid liability is imposed on the business with fines and late‐payment interest. Also be careful with multi-net contracts: tax is calculated on the reconstructed gross amount.

5. Withdrawals by a partner without a resolution and without tax

The partner withdraws money from the business account during the year and accounting records it as a loan. The loan grows year after year and at audit is reclassified as a profit distribution, with the 8% dividend tax, Fines and late fees. Avoidance: profits are distributed by board resolution with withholding tax applied, and personal withdrawals are kept separate from business funds.

6. Unnoticed tour thresholds crossed

Two thresholds change everything. A turnover of over 10,000,000 lek makes VAT registration mandatory, and late registration triggers retroactive VAT on sales made without it. Revenue over 14,000,000 lek takes the business out of the exemption. 0% rate of profit tax. Avoidance: the cycle is monitored every month and the threshold crossing is planned; it is not detected in December.

7. Personal expenses, undocumented, and cash over the new limit

Family fuel, private travel, purchases without a tax invoice. Upon audit, these expenses are removed from deductions, profit increases, and the difference is taxed with fines and interest. The deductible VAT is also lost when the document is missing, such as for machinery purchased without a proper invoice, resulting in a loss of 400,000 lekë VAT on a 2,000,000 lekë value.

From 2026, the risk of using cash increases. Payments between businesses exceeding 100,000 lek must be made through a bank, and breaching the limit is punishable by a 10% fine on the transaction value under Article 120. The old habit of making cash payments to suppliers has become a new mistake.

8. Unverified pre-populated statements

The newest systemic error. VAT declaration and the withholding tax They come pre-populated by the system and can be confirmed with a click. But the system only populates what it recognizes; new rent, a newly paid dividend, or an occasional honorarium must be added manually. An inaccurate statement is penalized under Section 115, and the error remains under your name, not the system's.

9. Missed deadlines and compressed correction time

Late filing costs 3,000 to 10,000 lek according to the category, Article 113 of the Law No. 9920, and now the fine is automatically imposed by the system after the deadline has passed. Late payment adds 0.06% per day plus a 7.8% late‐interest charge. Also Late-filed balance sheet It has its own fine.

The 2026 change makes this mistake more dangerous. The time to correct a return was cut from 36 to 24 months, and the personal annual return can be corrected within six months, up to two times. A mistake left for later can remain forever. Avoid it: use a financial calendar with notifications, appoint a single person responsible for deadlines, and review statements within the year—not when oversight is lacking.

10. The entire system is based on a person's memory.

The nine above-mentioned errors have a common denominator. They occur where statements depend on memory rather than on a system maintained according to the rules of Finance and Accounting, with a professional eye. The cost of a external economist It is almost always lower than the sum of the fines, late fees, and lost opportunities it prevents.

Old fines are forgiven on condition, until December 31, 2026.

The 2026 package also included the forgiveness of old obligations. Obligations up to December 31, 2014, are completely wiped out. For the years 2015 through 2019, fines, interest, and a portion of the principal are forgiven under an installment plan. For the years 2020 through 2024, fines and interest are forgiven only if the principal is paid in full by December 31, 2026.
