Tax return is an annual obligation that many people postpone until the last few weeks. However, in practice, the later you start, the greater the risk of errors and stress. Processing a tax return is not just a form, it is about checking the documents, correctly evaluating income and expenses, applying reliefs and, above all, meeting deadlines.
The risk of errors increases when time is tight
Tax returns are often processed at the last minute without sufficient checking. This can result in incorrect data, forgotten attachments, or incorrectly applied items, which can cause complications during the audit or the need for a corrected tax return.
Most common mistakes:
missing or incomplete documents,
poorly classified income (especially a combination of employment, business, rental, abroad),
incorrectly applied non-taxable parts, bonuses or deductions,
incorrectly stated advances and payments.
The most time-consuming part is finding the documents, not the actual confession.
Clients often underestimate how much time it will take. In the last few weeks, the following is addressed:
confirmation of taxable income from the employer,
documents for rent, business or other income,
confirmations from banks and insurance companies,
documents on tax benefits (e.g. child tax bonus),
information about paid contributions and advances.
If even one essential piece of information is missing, the return either cannot be filed correctly or must be corrected later.

Tax return also affects cashflow
Your tax return often determines whether you will have to pay back your tax or have an overpayment. When your return is filed late, the overpayment can have a negative impact on your budget.
Timely processing gives the opportunity to:
know in advance the amount of the surcharge,
plan your payment and avoid delays,
to gain a better understanding of what can be optimized (within the law).
In season, capacities are limited and everything takes longer
March is the busiest period. This means less time for consultations, higher workload for accountants, and often longer response times for additional questions or additional documentation.
If you want the confession to be processed with quality, with control and without improvisation, it is worth starting earlier.
Unnecessary fines and interest are the most expensive tax
Late filing or paying taxes can result in penalties and interest. Often, this is completely unnecessary money that can be easily avoided with simple preparation in advance.
