Deferred income (rozliczenia międzyokresowe przychodów) is a key element of correct bookkeeping that allows the accrual principle to be observed. Under the Accounting Act, not all cash received can immediately be recognised as revenue of the current period. Part of it has to be spread over time so that revenue is allocated to the periods it actually relates to. We record such items on an ongoing basis in the accounting books we keep as part of our bookkeeping services.
The deferred income mechanism allows businesses to avoid artificially inflating the financial result in one reporting period at the expense of later periods. This is particularly important for businesses that regularly receive prepayments, advances or payments for services to be provided in the future.
The accrual principle set out in Article 6(1) of the Accounting Act requires all income earned and attributable to the entity in a given financial year to be recognised, regardless of when it is paid. This means that income received before it is actually earned must be spread over time
The essence of deferred income
Deferred income follows directly from the need to apply the accrual principle in accounting. Under Article 41(1)(1) of the Accounting Act, it covers the equivalent of funds received or due from counterparties for services to be performed in subsequent reporting periods. It is recognised in line with the prudence principle, which means particular care when estimating and booking it.
The main purpose of deferred income is to ensure compliance with the principle of matching revenue and the related costs. Thanks to this mechanism, the income does not increase the financial result in the period the funds are received, but becomes revenue only in future reporting periods, when the service is actually performed.
The Accounting Act also lists other categories of deferred income, such as cash received to finance the purchase or construction of fixed assets, including fixed assets under construction and development work, if it does not increase equity (Article 41(1)(2)). In this case the amounts recognised as deferred income gradually increase other operating income, in parallel with depreciation of the fixed assets financed.
Negative goodwill, referred to in Article 33(4) and Article 44b(11) of the Accounting Act, is also recognised as deferred income (Article 41(1)(3)). It is a specific case that requires particular care when booking
In practice, deferred income applies where the entity receives payment before actually delivering goods or performing services. The most common examples are rent received in advance for several months, subscriptions paid in advance, ticket sales for future events and accommodation and travel bookings paid in advance. Advances received for goods or services to be provided in later periods need to be assessed separately.
Booking rules in the accounting books
Booking deferred income requires an appropriate accounting method that ensures the funds received are correctly allocated over time. Account 840 Deferred income is used for this purpose and is the basic tool for recording such business transactions.
The analytical records kept on this account must make it possible to determine the balances of individual deferred income items. This is key to managing deferrals properly and checking that they are released on time. The level of detail of the analytical records should match the entity's needs and the nature of its business.
Deferred income is booked in several stages. The first step is to record the receipt of cash in the bank account together with the related settlement with the customer. Next, an invoice is issued, which settles this balance and splits the revenue into the current part and the part to be deferred.
All income that needs to be spread over time is credited to account 840 Deferred income. The debit side of the same account records transfers of income received earlier to revenue of the current period, in line with the accrual principle
Revenue is gradually recognised in the relevant reporting periods by transferring the appropriate part from the deferred income account to the sales revenue account. This should be done systematically, in line with the schedule for performing the services or the passage of time to which the payments received relate.
The balance of account 840 Deferred income can only be a credit balance, which reflects the amount of deferred income awaiting release in subsequent periods. A zero balance on this account means that the entity has no income awaiting release in later periods.
Practical booking examples
To better understand how deferred income works, it is worth analysing a specific example of booking a property rental transaction. A company renting out commercial premises received PLN 18,000 in January 2025 as rent for three months: January, February and March 2025 (for simplicity the example ignores VAT).
Booking starts with recording the receipt of the payment in the bank account. In January 2025 the following entry is made: Dr account 130 Bank account PLN 18,000, Cr account 200 Settlements with customers PLN 18,000. This entry reflects the inflow of cash and the creation of an obligation to the tenant to provide the services.
The next step is issuing an invoice in January 2025, which settles the balance and splits the revenue. The entry is: Dr account 200 Settlements with customers PLN 18,000, Cr account 700 Revenue from sales of services PLN 6,000, Cr account 840 Deferred income PLN 12,000.
The revenue on the invoice is split because only the part relating to January 2025, that is PLN 6,000, can be recognised in the current period. The remaining PLN 12,000 is deferred as income of future periods
In the following months, the revenue attributable to each reporting period is released systematically. In February 2025 the entry is: Dr 840 Deferred income PLN 6,000, Cr account 700 Revenue from sales of services PLN 6,000. The same entry is repeated in March 2025.
This method ensures that revenue is recognised correctly under the accrual principle, in the period it relates to rather than when the payment is received. As a result, the entity's financial result in each month reflects the actual revenue attributable to that period.
Types of deferred income
Deferred income covers various categories of business transactions that need an individual approach in the books. Each type has specific features and needs appropriate treatment under accounting principles. On the cost side, a similar mechanism applies, for example, to prepaid expenses during a business suspension.
Advances received for goods or services need to be assessed separately. They concern situations where the customer prepays for goods or services that will be delivered or performed in future reporting periods. In the balance sheet under Annex 1 to the Accounting Act, advances received for deliveries and services have their own item among short-term liabilities (B.III.3 letter e), so as a rule they are shown as liabilities rather than as deferred income. Booking such advances requires particular care in determining when they are settled, which should be linked to the actual performance of the service.
Rent received in advance for several months is another important category. Here the key is to spread the payment received correctly over the individual rental periods, in line with the principle of even allocation over time. Each rental month should bear a proportional part of the payment received.
Subscriptions paid in advance require particular care when setting the release schedule. The release period should match the period in which the services covered by the subscription are provided, regardless of how often payments are made
Ticket sales for future events are a specific case of deferred income. Revenue from ticket sales should be recognised in the period in which the event takes place, not when the ticket is sold. This is particularly important for events organised on a recurring or seasonal basis.
Accommodation and travel bookings paid in advance are also deferred. Revenue from such bookings should be recognised in the period the service is actually provided, which requires careful planning of releases in line with the service schedule.
Control and management of deferrals
Effective management of deferred income requires appropriate control procedures to ensure that deferrals are correct and released on time. A key element is keeping detailed analytical records that allow ongoing monitoring of individual items.
The analytical records should include information on the title of the deferral, the amount, the release period, the release schedule and the status. Such data allows effective control of timely releases and identification of any irregularities in the booking process.
Regular reviews of deferral account balances are an essential element of internal control. These reviews should include checking whether individual items are still justified, verifying release schedules and identifying items that need to be released immediately.
Documentation of deferral processes should include clearly defined procedures for identifying transactions that require deferral, the method for setting release schedules and the rules for checking that releases are correct
Automating deferral processes can significantly improve the efficiency of managing deferred income. Accounting systems with automatic release modules can generate the relevant entries according to predefined schedules, reducing the risk of errors and ensuring timely releases.
Training accounting staff in the rules and procedures for deferrals is a key element of ensuring the quality of accounting processes. Staff should know how to identify transactions that require deferral, how to book them and how to check that releases are correct.
Reporting and tax aspects
Deferred income is important for the accuracy of the entity's financial statements and tax settlements. In the balance sheet under Annex 1 to the Act, deferred income is shown on the liabilities side in group B "Liabilities and provisions for liabilities", in a separate item B.IV "Accruals and deferred income", reflecting the entity's obligation to provide services or deliver goods in the future. How other liabilities are shown on that side is illustrated, among others, by presenting a ZUS instalment agreement in the balance sheet.
Presenting deferred income in the financial statements requires it to be classified into short-term and long-term parts. Deferrals to be released within the next 12 months are classified as short-term, and the rest as long-term.
In the profit and loss account, deferred income affects the amount of revenue shown in individual reporting periods. Correct deferral ensures that the entity's results are properly reflected and allows data to be compared between periods.
The notes to the financial statements should include information on the entity's rules for deferring income. Information on the methods for setting release schedules and significant changes in this area is particularly important
From a tax perspective, deferred income may affect the income tax base. It is key to keep the accounting records consistent with tax requirements, especially as regards the moment income is deemed earned for tax purposes.
Differences between the accounting and tax timing of revenue recognition may require deferred tax liabilities or assets to be recognised. This is particularly important for entities applying International Financial Reporting Standards or operating on a large scale.
The most common mistakes and how to avoid them
In accounting practice, the most common mistakes with deferred income concern incorrect identification of transactions that require deferral and incorrect release schedules. These mistakes can distort the financial result and breach accounting principles.
One of the most common mistakes is treating all prepayments received as current revenue, without analysing the period to which the services relate. This artificially inflates the result in the period the payment is received and understates it in the periods the services are actually performed.
Incorrect release schedules are another common mistake. Schedules should reflect the actual period in which services are provided or goods delivered, rather than being set arbitrarily to simplify the bookkeeping.
- No regular review of deferral account balances
- No detailed analytical records of individual deferral items
- Incorrect classification of deferrals as short-term or long-term
- Incorrect booking of release transactions
- No documented deferral procedures in the entity
Avoiding mistakes effectively requires clear procedures for identifying transactions that need deferral. These procedures should include criteria for recognising such transactions and rules for setting release schedules
Regular training of accounting staff and periodic reviews of accounting procedures are key to preventing mistakes. Particular attention should be paid to training on new types of business or changes in the entity's revenue structure.
Automatic controls in accounting systems can significantly reduce the risk of errors. These controls can include automatic alerts about transactions that require deferral and checks that release schedules are correct.
Implementation procedures and best practice
Implementing an effective deferred income system requires a systematic approach: analysing the entity's business, developing appropriate procedures and putting control mechanisms in place. The first stage should be identifying all types of transactions in the entity that may require deferral.
Analysing cash flows and service schedules helps identify the key areas that need particular attention as regards deferrals. Seasonality, production cycles and specific contracts with counterparties should be taken into account.
Accounting procedures should include clear criteria for identifying transactions that require deferral, the method for setting release schedules and the rules for checking that releases are correct. The procedures should be tailored to the entity's business and organisational structure.
A consulting firm received a prepayment of PLN 60,000 for a project carried out over 6 months. Instead of recognising the whole amount as revenue in the month the payment was received, the firm correctly spread the revenue over 6 months at PLN 10,000 a month, in line with the project schedule.
Implementing an IT system that supports deferrals can significantly improve the efficiency and accuracy of accounting processes. The system should allow release entries to be generated automatically and detailed analytical records to be kept.
Best practice in deferred income also includes regular reviews and updates of procedures in response to changes in the entity's business or in the law. Flexible procedures allow quick adjustment to new requirements without loss of quality in accounting processes.
Internal control and audit
An effective internal control system for deferred income should include mechanisms ensuring that transactions requiring spreading over time are correctly identified, booked and released. A key element is segregating duties between the people responsible for the different stages of the process.
Preliminary controls should include checking source documents to see whether deferral is needed. Particular attention should be paid to long-term contracts, prepayments and payments for services to be provided in the future.
Ongoing controls focus on correct booking of release transactions and timely releases in line with the agreed schedules. Regular reviews of deferral account balances help identify any irregularities and keep the records up to date.
- Set clear criteria for identifying transactions that require deferral
- Develop standard release schedules for typical transactions
- Introduce procedures for approval of release schedules by authorised persons
- Set up a system for monitoring timely releases
- Carry out regular reviews of deferral account balances
- Document all decisions concerning deferrals
Follow-up controls include checking that deferrals are complete and correct after the end of the reporting period. It is particularly important to check whether all releases have been made in line with the schedules and whether any unreleased items need adjustment.
Internal audit should regularly assess the effectiveness of the deferred income system. The assessment should cover the correctness of procedures, the effectiveness of internal controls and compliance with legal requirements and accounting standards
Documentation of internal controls should include a description of the control procedures performed, the irregularities identified and the corrective actions taken. Such documentation is the basis for assessing the effectiveness of the control system and planning future improvements.
Working with an external auditor on deferred income requires preparing appropriate documentation and providing access to detailed analytical data. The auditor should receive information on the procedures used and the reasons for the adopted release schedules.
Impact on financial analysis
Deferred income has a significant impact on the entity's financial ratios and on how investors and analysts interpret its results. Correct deferral ensures comparability of results between periods and allows a reliable assessment of the entity's development trends.
Profitability ratios can be significantly distorted by incorrect deferral of income. Recognising all prepayments received as current revenue artificially inflates profitability in the period the payment is received and understates it in the periods the services are actually performed.
Liquidity analysis also needs to take deferred income into account. Prepayments received increase the entity's liquidity, but at the same time create an obligation to provide services or deliver goods in the future.
| Ratio | Impact of deferrals | Interpretation | Corrective action |
|---|---|---|---|
| Return on sales | Smoothing of seasonal fluctuations | More stable results | Analysis of long-term trends |
| Liquidity ratio | Increase in current funds | Apparently better liquidity | Taking deferral obligations into account |
| Receivables turnover | Lower receivables balance | Apparently better collection | Analysis of the deferral structure |
| Revenue growth | Even spread of revenue | Realistic picture of growth | Year-on-year comparisons |
Debt ratios can also be affected by deferred income, which is shown on the liabilities side of the balance sheet as liabilities. A high deferral balance may suggest increased debt, even though it actually represents an obligation to provide services rather than to repay cash.
Financial analysts should pay particular attention to changes in the deferred income balance between periods. A significant increase may indicate higher sales of prepaid services, while a decrease may signal the performance of services prepaid earlier
Cash flow forecasting needs to take deferred income release schedules into account. These releases do not generate cash inflows when the revenue is recognised, which must be reflected in the entity's financial planning.
Communication with investors should include explanations of how deferrals affect financial results, especially where their level changes significantly. Transparency in this area increases investor confidence and makes it easier to interpret financial results correctly.
