Direct submission of the completed Form 3-NDFL through the web interface of the taxpayer’s Personal Account occurs instantly after entering the confirmation code received via SMS or the Gosklyuch application. This final step records the fact of contacting the tax authorities and starts an automatic check of control ratios. If you plan to return part of the funds paid or report income, digital filing is the fastest and most reliable way to interact with Federal Tax Service.
Unlike the paper version, electronic document management eliminates the risk of losing papers and allows you to track the status of the verification in real time. Tax code equates the electronic signature created in the Personal Account to a handwritten one, giving the file legal force. The user does not need to attend the inspection or send registered letters, since the entire procedure is carried out remotely.
To successfully complete the process, you only need to have a valid account on the nalog.ru portal and a verified account. The system will automatically pull up income certificates if your employer has already submitted them to the database, which greatly simplifies filling out the fields. The program corrects errors in calculations on its own, offering to correct the data before the final submission.
Preparation for filling out the declaration electronically
Before entering the service interface, you must collect a package of documents confirming your right to deduct or have income. Digital copy passports, INN and 2-NDFL certificates must be ready for downloading or manual data entry. If you are claiming medical or educational expenses, scan contracts with medical or educational institutions.
Keep the originals of all documents for at least 3 years, as the tax office may request them for a desk audit even after successful online submission.
It is important to check the relevance of the software if you use specialized programs to prepare files, although the Federal Tax Service web service does not require the installation of additional applications. A modern browser with JavaScript and pop-up support enabled is sufficient. A stable Internet connection is critical when the final file is generated and signed.
⚠️ Attention: Make sure that the 2-NDFL certificate correctly indicates the code of the tax authority where you plan to submit the report. An error in the Federal Tax Service code will result in the declaration being sent to the wrong address and will have to be redone.
Authorization in the Taxpayer’s Personal Account
Access to the reporting functionality is available only after authorization on the official portal. Login via Public services, which requires a verified account on the unified portal. An alternative way is to use a qualified electronic signature or login card obtained from any tax office.
The login process through the ESIA (State Services) takes a few seconds and does not require remembering separate passwords for the Federal Tax Service website. After successful identification, the system redirects the user to the personal section, where the entire tax history is displayed. This is where the button to start working with new documents is located.
| Login method | Prerequisites | Access speed |
| :--- | :--- | :--- |
| Through State Services | Confirmed ESIA account | Instantly |
| Login card | Physical card from the Federal Tax Service + PIN envelope | Requires pick up in office |
| Electronic signature | Valid CEP certificate + reader | Depends on PC setup |
What to do if the password for State Services is lost
Access is restored through the standard procedure on the gosuslugi.ru portal. After changing your password, you must wait about 15-30 minutes to synchronize the databases before logging into the tax website.
Selecting the type of declaration and year of the reporting period
In the “Income and Deductions” menu, select the “Declarations” option, and then click the “Submit 3-NDFL declaration” button. The system will prompt you to select the reporting year for which you want to report. It is important to understand that in the current year reports are submitted for the previous calendar period.
If you are submitting a declaration for the first time, the interface will prompt you to fill out the data again. For those who have already submitted reports previously, the “Fill out a new declaration based on last year’s data” function is available. This allows you to copy permanent parameters such as address and details, saving time on entering repetitive information.
Choosing the right year is critical, as tax rates and social deductions may change depending on the legislation of a particular period. An error in choosing a year will result in the generation of a document with incorrect control ratios.Filling out data on income and deductions
The central part of the process is entering information about income received. The “Income” section often already contains data automatically transmitted by employers. All you have to do is check the amounts and, if necessary, add sources of payments that were not reflected in the database, for example, income from the sale of property or royalties.
Next comes the “Deductions” block, where the purpose of filing the declaration is indicated. You can choose a tax refund on medical expenses, education, home purchases, or standard deductions. For each type of deduction, the system will request the download of the corresponding documents in PDF or JPG format. The quality of the scans must be readable so that the inspector can verify the information.
☑️ Checklist before sending the deductions section
When filling out fields with expenses, use only numbers, without spaces or currency signs, unless the system requires a different format. Social deductions have limits that the program takes into account automatically, but you should still control the maximum amounts yourself.
Checking control ratios and calculating tax
After entering all the data, the system performs an automatic check for logical errors. If the amount of expenses exceeds income or incorrect codes are specified, the interface will highlight the problem fields in red. Such warnings cannot be ignored, since the declaration will not pass the primary format and logical control.
At this stage, the total amount of tax payable or refundable from the budget is formed. Study the calculation carefully: sometimes users forget to take into account amounts already paid by the employer, which distorts the balance. Correcting the entered data instantly recalculates the final result.
If after all calculations the amount to be returned is zero, but you must submit a declaration (for example, when selling property), this is normal. The main thing is to record the fact of receiving income.
Signing and sending a declaration to the Federal Tax Service
The final stage is signing the generated file. For this purpose, a password is used, which you come up with and enter in a special field at the time of sending. This password becomes your key electronic signature for this document. It must be remembered or saved, as it may be needed to revoke a declaration or submit an amendment.
After entering the password and clicking the “Submit” button, the document is encrypted and sent to the tax office. The status in your personal account will change to “Registered”, which means the file has been successfully received by the Federal Tax Service server. From this moment the countdown of the desk audit period begins, which is up to three months.
⚠️ Attention: After sending the declaration, changes can only be made to it by submitting an updated declaration (adjustment). Please check all details carefully before final confirmation.
How to find out the password for an electronic signature
You come up with a password yourself when you first submit your declaration online. If you have forgotten the password you set earlier, the next time you submit, the system will prompt you to create a new one, but you may need the old password to revoke previous documents.
Frequently asked questions (FAQ)
Can I submit a return online if I do not have an electronic signature?
Yes, to submit 3-NDFL through the taxpayer’s Personal Account, a separate purchased electronic signature is not required. You create an analogue of a handwritten signature immediately at the time of sending the document by setting a password in the service interface.
How long does it take to check a declaration submitted online?
The period for the desk audit is 3 months from the date of registration of the declaration in the system. After its completion, another 10 days are allotted for the return of funds to your current account, if the amount to be returned was declared.
What should I do if the system writes an error when uploading documents?
Make sure that the files do not exceed the allowed size (usually up to 10-20 MB) and are in a supported format (PDF, JPG, PNG). Also check the readability of the text on the scans. If the problem persists, try using a different browser or device.
Do I need to bring paper originals to the tax office after filing online?
No, originals are carried only if the inspector identifies inconsistencies during a desk inspection and requests them personally. However, it is mandatory to keep the originals at home during the limitation period (3 years).
