In limited and joint-stock companies in particular, the movement of money between the company and its partners is perfectly normal. A partner may make a payment on behalf of the company, meet the company's temporary cash needs from their own resources, or withdraw money from the company account. The problem here is not the movement of money itself.

The main problem is that it's unknown why this money moved, the transaction wasn't documented, and the resulting balance was held in a joint current account for years.

A joint current account is not simply an account where unknown money movements are parked. Because as the balance grows, the matter goes beyond mere accounting entries. Many issues can arise, such as comparable interest, customary interest calculations, transfer pricing, VAT, hidden profits, and hidden capital.

Therefore, the joint current account should be viewed not with the mentality of "we'll check and adjust it at the end of the year," but as a financial account that needs to be managed throughout the year .

What is a joint current account?

The joint current account is the account used to track the debt and credit relationships between the company and its partners. If the company has receivables from a partner, these amounts are tracked under receivables from partners; if the company owes money to a partner, these amounts are tracked under liabilities to partners. However, simply looking at which side the balance belongs to is not sufficient.

For example, the same 1,000,000 TL;

• from payments made by the partner on behalf of the company,
• from the temporary financing provided to the company by the partner,
• from the advance given by the company to the partner,
• from personal withdrawals made by the partner from the company account

may be the cause.

The amount may be the same, but the tax and legal consequences of the transactions are not. Therefore, the first thing I look at is how the balance was formed, even before considering the amount itself.

The company is a creditor of the partner.

If a partner withdraws money from the company's cash reserves or bank account, makes personal purchases using the company credit card, or fails to repay an advance given to them, this may create a receivable for the company.

The crucial point here is not that the balance was created even once, but how long it has remained open.

A partner may have temporarily withdrawn money from the company and repaid it shortly afterward. That's a different situation. However, if the balance is constantly growing, not being settled for months or even years, and there's no realistic repayment plan in place, then we can start talking about allowing a partner to use company resources.

From this point onwards;

• comparable interest,
• customs calculation,
• transfer pricing,
• VAT

Topics such as these need to be evaluated separately.

The company owes money to the partner

The opposite situation is also quite common. A partner may pay company expenses from their own pocket or transfer money to the company to meet its cash needs. In this case, the company owes money to the partner. The question I am particularly looking at here is this:

Is this truly temporary financing, or is it a common debt that has been used as capital for years?

Because if a partner is continuously transferring funds to the company, and the company cannot operate without these resources, the issue is no longer just the balance of account 331. There may be another problem in the company's financial structure. The amount of the debt, how long it has been ongoing, whether interest is being applied, and the company's equity structure should all be considered together. If the necessary conditions are met, provisions regarding disguised capital may also come into play.

Key tax and accounting risks

Calculating interest and customary rates in accordance with comparable transactions.

If lending company funds to a partner constitutes a financing relationship, then calculating interest in accordance with market rates becomes relevant. Here, not only the amount is considered, but also the length of time the money remains in the partner's possession. Although some court decisions state that calculating market rates is unnecessary, the generally accepted practice is to calculate market rates. You will understand the reasons for this better in the sections below.

However, there is a classic mistake that is made in this regard:

Finding an interest rate online or in the market and applying it to the joint current account. This alone is not sufficient.

When determining the interest rate, the following factors are considered in the transaction:

• currency
• maturity
• company's financing terms,
• market interest rates,
• credit risk
• comparable operations

They should be evaluated together.

The goal isn't to find an interest rate, but to be able to explain why that rate is used.

Transfer pricing and concealed profit risk.

Although it is not often included in the Corporate Tax Returns of many SMEs , a company and its partner are considered related parties. Therefore, lending and borrowing transactions between the company and its partner are also evaluated in terms of transfer pricing regulations. If company funds are provided to a partner without interest or under conditions significantly different from market conditions, the risk of disguised profit distribution through transfer pricing may arise. However, on the other hand, it is not correct to assume that there is "disguised profit" as soon as every partner sees their current balance.

The process;

• why it was done,
• how long it lasts
• commercial reason,
• Refund method,
• applied interest rate

They should be evaluated together.

But naturally, defending the unexplained, constantly accumulating, and ever-growing joint current account balance becomes increasingly difficult.

VAT and documentation requirements.

When a loan provided by the company to a partner constitutes a financing service, the issues of VAT and documentation related to the calculated interest also arise. Therefore, simply issuing a single accounting voucher for interest accrual at the end of the year is not always sufficient. The period for which the interest is calculated, when the invoice will be issued, when the taxable event occurred, and which declaration period it falls under must all be considered together.

The important thing here is not just creating the accounting record: it's recording the transaction in the correct period, with the correct documentation, and with the correct tax implications.

Suspicious cash register and bank transactions

A significant portion of the problems we see in the joint current account actually begin in the cash and bank accounts.

High cash balances that cannot be explained by the volume of activity, consistently round-amount withdrawals, or bank statements containing only terms like "payment" or "transfer" can later create serious follow-up problems.

For example, let's say 500,000 TL was sent to a partner. The bank statement simply says: "Payment." Three months later, the question naturally arises: Payment for what? You can make an accounting entry. But the mere fact that an accounting entry has been made does not, by itself, prove the commercial justification for that transaction. Therefore, bank statements should not be underestimated. A few words of explanation that seem unnecessary to you today might help you remember why the transaction was made six months later.

Financing and disguised capital provided by the partner.

The financing provided by the partner to the company should also be monitored.

If the company is constantly borrowing from its partners;

• the amount of the debt
• its relationship with equity,
• usage period
• interest expenses, if any

They should be examined together.

If certain conditions are met, provisions regarding disguised capital may come into play. Consequently, the tax treatment of interest, exchange rate differences, and similar financing expenses may also change. Another issue is the financial statement side of things. High-value debts that have been sitting in a partner's current account for years also affect the company's financial structure. If the money transferred to the company by the partner is no longer just temporary support but is actually being used permanently in the company, then the following question should be asked:

Should this money truly remain as debt, or should it be structured as equity?

This decision should not be made solely based on tax considerations.

How should transactions be documented?

In my opinion, the first requirement for healthy joint current account management is very simple: Know why each money transaction is made. Bank statements show that money has been sent or received. But they don't always show why it was sent.

Depending on the nature of the transaction;

• Invoices, receipts, and expense forms for expenses incurred by the partner on behalf of the company.
• A written loan or financing agreement for temporary financing provided to the company,
• explanatory bank instructions or internal company approval for cash withdrawals,
• Advance payment requests and closing documents,
• Bank statement referring to the relevant debt in repayments,
• If interest is applied, an interest/rate calculation table and data supporting the rate used.
• Company decisions and legal documents required for capital commitment or capital increase transactions.

It must be filed.

In my opinion, the most important rule here is this: Don't try to produce the document six months after the transaction has been completed.

The explanation and supporting evidence for any financial transactions should be created on the same day they occur, if possible. Because six months later, everyone remembers something different. Moreover, documents prepared later and inconsistent with the actual situation can increase the risk instead of reducing it.

Practical checklist for joint current account.

When examining a joint current account, we are essentially looking for answers to a few fundamental questions.

Balance direction:
Does the company owe money to the partner, or does the partner owe money to the company?

If there is more than one partner, each partner's balance must be tracked separately.

Reason for the action:
Why did the money move?

The bank statement should be matched with a contract, invoice, expense receipt, or other supporting document if possible.

Aging:
How long has the balance been open?

Movements that have been open for a long time should also be examined, and an action plan should be developed for them.

Interest:
Has a genuine financing relationship been established?

If applicable, arm's length principle and tax implications should be evaluated.

Document:
Is there a basis for the transaction?

Missing documents should be completed during the process whenever possible.

Authorization:
Who approved the outflow of funds?

Establishing authorization and transaction limits for cash outflows within a company is especially important for growing businesses.

Agreement:
Are the company's accounting records the same as the partner's records?

I find it useful to have written agreements at regular intervals.

A viable management model for SMEs.

Separate personal and company expenses.

The simplest rule is sometimes the most frequently violated. The company bank account and company credit card belong to the company. Partners' personal expenses should be avoided as much as possible when making transactions through the company. If an accidental transaction occurs, it should not be left unnoticed for months; it should be recorded immediately, and if necessary, the partner should be reimbursed to the company.

Monitor each partner separately.

In companies with multiple partners, consolidating all transactions under a single current account creates a significant tracking problem.

Each partner;

• balance
• transaction date,
• explanation,
• currency
• supporting document

They should be monitored separately.

The effects of exchange rate appreciation, particularly in foreign currency movements, should also be taken into consideration.

Prepare a monthly aging report.

“The partner’s balance is 2 million TL.” This information alone doesn’t tell me much. What I want to know is: How much of this 2 million TL was generated last week, and how much has been sitting in the account for nine months? Because the real risk often lies in the age of the balance before its size. Therefore, regular aging reports should be prepared for partner current accounts, and transactions that have not been closed for a long time should be monitored separately.

Don't wait until the end of the year.

In my opinion, the biggest mistake made with joint current accounts is this: “We’ll review and correct it at the end of the year.” Often, when you look at it at the end of the year, the documents are lost. The reason for the bank transaction is forgotten. The current balance has grown. Then we start discussing interest, VAT, and documentation issues from previous months. Therefore, joint current accounts should be part of the monthly closing, not the annual closing . Cash, bank, credit cards, employee advances, and joint current accounts should all be checked together. If a tax-related action is required, it should be taken before the relevant declaration period ends.

Structure sustainable financing correctly.

If the money transferred to the company by the partner is no longer just short-term cash flow, the structure of the financing needs to be re-evaluated.

Money;

• Will it remain as a debt?
• Will there be a capital increase?
• Will a different financing model be used?

The answers to these questions should not be given solely by looking at taxes.

The company's;

• cash flow,
• repayment capacity,
• equity structure,
• the situation from the perspective of company law,
• Bank and credit relations
• partners' expectations

They should be considered together.

Conclusion: Do not use the joint current account as a "parking account".

The fact that a joint current account has a balance is not the problem in itself. The problem is not knowing why the balance was created, not having any documentation, and it being carried for years without any action being taken. In a well-managed joint current account, we should always be able to answer three questions:

1. Why did this money move?
2. When will it close?
3. What are the tax implications?

If we cannot give clear answers to these three questions, we first need to understand what the transaction actually is, instead of trying to close account 131 or 331. Because the main issue in a joint current account is not to zero out the account balance.

The main issue is being able to explain why that balance is there.
