Business Travel for Employees: Documentation, Payments, Expense Reports, and Mandatory Reporting in 2025–2026

In most companies, issues with business travel do not arise while the employee is away. They surface after the employee returns. That is when it becomes clear that the travel order was issued retroactively, receipts exist only in a messenger thread, the expense report was submitted late, and accounting and HR have different understandings of who was responsible for what.

An employee business trip is not simply a work-related journey. It is a structured process with a clear sequence of actions, documents, and deadlines. If that process is not formally defined, it almost inevitably leads to problems: conflicts with employees, tax risks, and confusion around expenses.

In this article, we explain when a trip must be formalized as business travel, which documents are required, which expense reporting deadlines must not be missed, and what risks arise if the process is not properly documented.

When Is a Trip Considered Business Travel and Who Must Formalize It?

Let’s begin with the key issue that causes most mistakes: not every work-related trip qualifies as business travel.
Business travel is an official assignment outside the employee’s permanent workplace, carried out at the employer’s instruction, for a defined period and with a specific purpose. It is this combination of factors that triggers documentation and reporting requirements.

Typical situations where business travel must be formalized:

• a trip to a client or partner for negotiations;
• participation in a conference, exhibition, or audit;
• installation, service, or inspection work at another site;
• travel between company branches to complete a one-time assignment.

A common mistake is confusing business travel with a travel-based role. If travel is a permanent part of the employee’s job duties (for example, sales representatives or service engineers), this must be stated in the employment agreement or job description. In that case, each trip is not formalized as a separate business trip.

A practical marker: if the trip is one-off, has a specific purpose, and the employee returns to their regular workplace afterward, it qualifies as business travel and must be documented accordingly.

What Documents Are Required for Business Travel?

Travel-related paperwork is often treated as a formality. In reality, it protects both the company and the employee. For clarity, let’s divide the documents by stage and explain what is mandatory, recommended, and optional.

Documents Before the Trip

The first stage is documenting the fact of the trip.

Mandatory: a business travel order. This is the core document without which the trip does not legally exist. It must include the employee’s full name, destination, dates, purpose of the trip, and expense reimbursement terms.

Recommended:

• a service memo or assignment describing what must be accomplished;
• an approved budget or expense limits.

Optional: additional internal forms or instructions, unless required by company policy.

In practice, HR may issue the travel order but fail to define who approves expenses. The employee spends more than expected. After returning, a dispute arises: accounting refuses the expenses, and the manager does not recall the agreement. This could have been avoided by setting limits before departure.

Documents During the Trip

During the trip, the employee collects supporting documents for expenses.

Mandatory (if expenses occur):

• travel tickets;
• invoices or receipts for accommodation and meals;
• other documents confirming expenses related to the assignment.

Recommended:

• immediately store documents in electronic format (high-quality photo or scan);
• clearly indicate which expense each document relates to.

Not mandatory:

• paper originals of supporting documents;
• duplicating electronic documents in paper form;
• additional internal forms if the expense is already confirmed by a valid electronic document.

In a properly organized digital workflow, the employee uploads the invoice or electronic receipt to the travel task. HR and accounting can review it immediately. All expenses are recorded within a single process.

Documents After Returning from the Trip

Returning from a business trip is not the end of the process but its final and most sensitive stage. This is where expenses are finalized, deadlines are confirmed, and risks either disappear or materialize.

Mandatory:

• submit all supporting documents in the format defined by the company;
• file an expense report if the employee received advance funds, overspent, or must return unused funds.

Recommended:

• complete this within the first 24–48 hours after returning;
• link documents to the specific trip;
• verify that expenses comply with approved limits and the trip’s purpose.

In a well-structured process, the employee completes their part of the task, and HR and accounting work within the same electronic environment without chasing files.

Electronic Documents in Business Travel: What Can Be Signed with a Qualified Electronic Signature?

In 2025–2026, the question of electronic documentation is no longer theoretical. The Law of Ukraine On Electronic Documents and Electronic Document Management allows electronic documents signed with a qualified electronic signature to have full legal validity.

This means:

• the business travel order may be electronic;
• an electronic expense report signed with a qualified electronic signature is fully valid;
• approval routes and signature workflows can be fully digital.

Business travel documents are generally classified as short-term retention documents. Under Ukrainian law, such documents may be stored exclusively in electronic form without mandatory paper copies. Supporting documents such as receipts and invoices may also be electronic, provided the company defines internally what formats are accepted and how they are verified.

When all travel documents are collected in a single electronic environment with defined approval routes and an electronic archive, the risk of losing them later is significantly reduced.

Payments During Business Travel: Per Diem and Expense Reimbursement

Payments are the most sensitive part of business travel because this is where employee expectations, internal policies, and accounting requirements intersect.

Per Diem

Per diem compensates daily expenses without requiring proof of every minor purchase. The amounts and rules depend on:

• the category of the company;
• internal policy;
• for public institutions, the limits established by Cabinet of Ministers Resolution No. 663.

Always verify current statutory limits or internal rules before specifying amounts.

Reimbursable Expenses

Typically reimbursed:

• transportation;
• accommodation;
• other expenses directly related to the assignment, supported by documents.

In a well-organized process, the employee purchases a ticket, records the expense in the system, and attaches supporting documents. Dates of purchase, payment, and the trip period are clearly reflected. Accounting can confirm that the expense is directly connected to business activity, reducing tax risks.

Expense Report: When It Is Mandatory, How to Prepare It, and Which Deadlines Must Not Be Missed

The expense report is where HR and financial processes intersect. It confirms that funds issued or spent during the trip were used properly and do not create taxable income for the employee.

An expense report is required if the employee:

• received advance funds before or during the trip;
• incurred overspending to be reimbursed;
• failed to return unused advance funds within the established timeframe.

If funds passed through the employee, the Tax Code of Ukraine requires transparent reporting.

Submission Deadlines

According to subparagraph 170.9.3 of the Tax Code of Ukraine, the expense report must be submitted no later than the end of the month following the month in which the business trip was completed.

Failure to meet this deadline may result in tax consequences for the employee.

Form and Procedure

The approved form is the Report on the Use of Funds / Electronic Money Issued for Business Travel or Under Account, established by Ministry of Finance Order No. 841. Legislation allows this form to be completed and submitted electronically.

In practice, the expense report may be:

• generated within an electronic system;
• signed with a qualified electronic signature;
• approved without paper copies.

Signing and Approval Workflow

In most companies, the expense report follows this route: employee → accountant or responsible officer → manager.

The employee confirms the accuracy of expenses and documents. The accountant verifies compliance with legislation, internal policy, and deadlines. The manager provides final approval.

A qualified electronic signature has the same legal force as a handwritten signature and allows remote approval without physical paperwork.

Common Mistakes in Business Travel and How to Avoid Them

Most travel-related problems repeat themselves and are organizational rather than legal.

Common mistakes:

• no travel order issued or missing key details;
• confusion between business travel and a travel-based role;
• missing or illegible supporting documents;
• unreturned advance funds or missed reporting deadlines, resulting in taxable income;
• no defined approval workflow, with decisions made informally in chats.

Most of these issues arise not from negligence but from the absence of a clearly defined process. When responsibilities, templates, and deadlines are set in advance, the risk of error decreases significantly.

How to Organize Business Travel in Vchasno.Kadry Without Chaos

In Vchasno.Kadry, business travel can be managed as a single structured process rather than a collection of scattered files and chat messages.

The task is closed, and all documents remain properly organized in the electronic archive.

Conclusions

Business travel does not require complex solutions. It requires consistency. When documentation rules, reimbursement policies, and reporting deadlines are clearly defined and applied equally to everyone, the process no longer depends on individuals and does not create tension between HR, accounting, and employees.

It is advisable to start by:

• reviewing whether the company has an approved travel order template and list of required documents;
• formalizing expense report deadlines in internal policies;
• organizing the entire workflow in Vchasno.Kadry so that documents do not get lost or accumulate at the end of the month.
