Receipts and attachments
When you make additions and corrections to your pre-completed tax return in MyTax, the service will ask you for the required information in different sections of the tax return. Just fill in the requested details in the appropriate fields. You do not need to attach any receipts or other documentation to the tax return. However, keep them in a safe place for possible future use.
Further, the MyTax view of your tax return does not contain fields for free-form text. We will contact you either by letter or by telephone to ask you to provide additional information, if necessary. The Tax Administration’s phone numbers begin with 0295.
In some exceptional cases you can add an attachment in MyTax: one such case is if you are filing information on dealing in securities. In that case, you will see the header Attachments and the link Add file.
Please note that MyTax does not contain numbered forms (such as Form 7H Rental income – Apartments in a housing company). File different types of income under different headers in MyTax: for example, there is a separate section for rental income.
If you file on paper, do not enclose any receipts or other documentation with your tax return. We will ask you for them if necessary.
Which receipts must I keep?
You do not need to keep receipts for any information that is correct on your pre-completed tax return. A typical example is documentation on wage and loan details. Further, you do not need to keep receipts for your commuting expenses. Keep the driver’s log, however, if you have one.
If you make additions or corrections to your tax return, keep all the receipts and documentation relating to them, such as
- contracts, invoices and payslips relating to the tax credit for household expenses
- documentation relating to the purchase or transfer of property, such as deeds of sale, deeds of estate distribution and deeds of gift
- bank documentation on purchase and sale of securities
- receipts relating to expenses for the production of income, such as purchase of tools.
How long must I keep the receipts and documentation?
Keep the receipts and other documentation for 3 years after the end of the tax year. In some exceptional cases you must keep the receipts even longer: see the Tax Administration decision for exceptions (in Finnish or Swedish).
Documentation on the purchase of assets or on the costs relating to major improvements made in your apartment should preferably be kept even longer. You may need the documentation later when calculating capital gain or loss arising from the sale of property.
Note that you can store the information in electronic form.
Documentation obligation
The documentation obligation applies to
- rental activities
- investment activities, i.e. purchase of securities, investment fund units and other such assets, and dealing in them
- agriculture and forestry
- production of income in the case that you are not an entrepreneur. Production of income includes activities such as dog breeding or working as a freelancer or a day care provider.
In practice, the documentation obligation means that you must make notes or keep documentation showing a sufficiently detailed itemisation of your income and related expenses.
Make notes in chronological order. Enter income as received when you withdraw it or when it is recorded on your bank account. Enter expenses for the date of payment.
As regards investment activities, for example, you must enter the purchase dates and prices and the selling dates and prices. You do not need to keep a separate record: it is enough that you have the documentation available when needed. In practice, you only need to keep the bank statements and documents you receive from your book-entry account operator in chronological order.
