In Ankara, current VAT returns go through e-Beyan. Older corrections stay on BDP. Provisional tax in Ankara has not moved to the new screen yet.
The 14 October 2026 announcement from the Turkish Revenue Administration looks, at first, like one sentence for a taxpayer in Ankara: the current VAT return is now accepted on the new e-Beyan system. The problem is treating that sentence as if it covered every return. The question arriving at offices this month is the same. The program opens, the VAT page is no longer where it was, or the opposite happens and a correction is hunted on the new screen. Both waste the day. The door depends on the type of return and on the period.
Ankara is already inside this move, together with every province except Istanbul. Current-period returns KDV1, KDV2, KDV2B, KDV4 and KDV9015 are filed from e-Beyan on the Digital Tax Office. Istanbul starts the same step on 1 November 2026, for the October 2026 period. Ankara does not wait for that date. Opening the old Return Preparation Program (BDP) for a current VAT return ends with a file that looks ready and will not send.
The move did not carry everything. A first return for an earlier period, and a correction for those periods, stays on the old e-return system, BDP. The announcement says so. Provisional income and corporate tax for a taxpayer in Ankara is also outside the five pilot provinces. The July-September provisional return in Ankara still goes through BDP. Tax consulting this month is as much about picking the screen as about the figure.
Which screen takes a current VAT return in Ankara?
For the current period, the address is the Digital Tax Office and e-Beyan inside it. Installing BDP and producing an XML file is not the path for current VAT in Ankara. The screen opens in the browser. Downloading a program, chasing a Java version and waiting for a package update are out of this return. That does not make the accounting software useless. If the software is connected to the e-Beyan web service, the return can leave from there too. If it is not connected, pressing send as though the service existed leaves the file on the road.
On the e-Beyan home page, open the user name at the top right, then Help, e-return documents, and Get started. The VAT page notes are there. Skipping this and hunting the old BDP menu makes a moved screen look closed. Integration is separate: the accounting program has to be prepared for e-Beyan. If it is ready, current VAT can go by web service. If it is not, file from the Digital Tax Office screen. Check that on a weekday, not in the last hour.
Why do older periods and corrections stay on BDP?
The new system took the current period. It did not take the past. The announcement leaves a first return for an earlier period, and a correction of those periods, on the e-return system, BDP. If a invoice difference shows up in a June VAT return in Ankara, that correction is not searched for inside e-Beyan. It is filed from BDP. September, or whichever period is current, sits on e-Beyan. The same tax, two doors.
Hearing “VAT is on e-Beyan now” and moving every VAT job across is how the correction disappears from the list. The old program has to stay until older periods are finished, and the new screen stays open for the current period. The e-ledger and e-invoice guide makes a similar point: the document decides the channel. Before sending, write the month, whether it is a first return or a correction, and which system Ankara uses for that pair. If the three do not agree, do not send. The VAT calculator shows the amount. It does not choose the system.
Provisional tax in Ankara has not moved with it
From 1 October 2026, the July-September 2026 provisional income and corporate tax return is accepted on e-Beyan in five pilot provinces: Afyonkarahisar, Eskişehir, Kayseri, Kırıkkale and Kırşehir. Ankara is not on that list. Provisional tax in Ankara did not move to the new screen on the same day as VAT. It is still filed from BDP. The sentence “everything is e-Beyan now” misses provisional tax in Ankara.
The statutory day is the 17th of the second month after the quarter. For the third period of 2026 that day falls on 17 November. Notices describe the final hour as both 23:59 and 24:00, so download the return and the assessment slip before that day rather than debating the clock. The return calendar shows the day. This piece shows the screen. Returns the notice does not name, such as withholding or the annual returns, should not be treated as moved in Ankara until a later notice says so. An empty menu means the return has not been taken onto that screen yet.
A short check before you send
The order used in the office this month is simple. Write the tax first. Then the period. Then the system that pair uses in Ankara. Current VAT means e-Beyan. An older VAT return or a correction means BDP. Provisional tax means BDP if the taxpayer is in Ankara, and e-Beyan if they are in one of the five pilot provinces. If the software has a web service, sending can be tried from there. If not, use the screen. Last, download the assessment slip. Without the slip, the send is not finished.
| Return | Period | System in Ankara |
|---|---|---|
| KDV1, KDV2, KDV2B, KDV4, KDV9015 | Current period | e-Beyan |
| The same VAT returns | Earlier period, first filing or correction | Old e-return (BDP) |
| Provisional income and corporate tax | July-September 2026 and after | BDP. e-Beyan only in five pilot provinces |
| Current VAT in Istanbul | From the October 2026 period | e-Beyan on 1 November 2026. Ankara does not wait |
The last row is there so an Ankara file is not locked to Istanbul’s calendar. Someone who applies the neighbouring province’s date delays a screen that is already open in Ankara. What gets delayed is the filing.
Attention before sending
These shares are the office’s priority before sending. They are not an official statistic.
The books sit behind this split. A missing invoice breaks the return no matter which screen is chosen. If a gap in the papers is talked through on the accounting side before the period closes, the e-Beyan day has fewer surprises. A new screen does not retire the paperwork.
Frequently asked questions
Is the VAT return in Ankara filed on e-Beyan?
Current-period KDV1, KDV2, KDV2B, KDV4 and KDV9015 returns are filed on e-Beyan in Ankara. Istanbul starts on 1 November 2026. Ankara does not wait for that date.
Which system takes a correction?
A first return for an earlier period, and a correction of those periods, is filed from BDP, the old e-return system. Moving the current period to e-Beyan does not move an older month’s correction onto the new screen.
Has provisional tax in Ankara moved to e-Beyan?
No. The July-September 2026 provisional return is on e-Beyan only in Afyonkarahisar, Eskişehir, Kayseri, Kırıkkale and Kırşehir. In Ankara, provisional tax continues on BDP.
Are e-Beyan and BDP the same program?
No. e-Beyan is the new screen inside the Digital Tax Office. BDP is the older Return Preparation Program installed on a computer. In Ankara both stay side by side for a while. One is for current VAT, the other for older periods and for provisional tax.
What if the accounting software is not connected?
Without a web service, current VAT is filed from the e-Beyan screen on the Digital Tax Office. Forcing an old XML into the new system is not a filing. If the connection exists, the service can be used too. Test that before the filing day, not on it.
If the assessment slip does not download, has the return gone?
No. The filing is finished when the slip is produced. Even if the screen looks done, do not close the period before you download and keep the slip.
Final word
In October 2026 the job in Ankara is not memorising a new rate. Keep current VAT on e-Beyan, keep an older correction on BDP, and keep provisional tax on BDP as well. Piling the three onto one screen is not what the announcement says. As 17 November gets closer, check the door first and the figure second.
If you want the list of your own returns matched to a system, write through the tax consulting page or the contact form to the office in Kızılay. Splitting the periods in a first meeting takes less time than searching for a screen on the last day.
