As with anything here dealing with KRA, it is hard to tell.
Technically the withholding tax is supposed to be a final tax. Especially if you are a non-resident.
My advice. Always get a TCC whether or not you file your bond income. That way you are covered each year if they lete nyoko nyoko.

I agree. That's where the TCC comes in. It's a legal document admissible in court showing you are tax compliant. If withholding tax is a final tax (at least for non residents) then one does not need to worry. For residents, the worry is not that you did not pay enough tax and hence accrue penalties) but how to recover the taxes paid if you overpaid. Most people do not even bother since the overpaid % is negligible at best.

I registered for TMD
Very easy process. Do not waste your time printing and filling the form like I did. The real form is 3 pages long, not the single page they post online, so just go to CBK and fill it there. Does not take more than 10 minutes.
Within 3 hours I had received a text saying I'm registered.
Using their USSD I set my PIN and logged in.
Yes, you are able to see bonds and bills on offer.Have not traded any yet.
They send you nifty little alerts whenever each coupon payment hits your account (but as expected...the alerts come hours later in the evening, not realtime.) Those alerts only say bond FXD blah blah blah has paid a coupon to account with digits ending XYXZ.
You can also check your total portfolio balance.
And query a particular bond or bill you own.
Overall this is a wonderful service. CBK finally left the dark ages. Now they should link it to secondary trading eg I assume the SC service some of you are talking about above. You still need to go through an outside party to trade your bills or bonds.
Good luck to all.

Bilas! You pay as you have always paid. For me it has been bank transfer direct into my virtual account. I assume you can also do m-pesa to virtual account if CBK has a paybill but I highly doubt this. Someone else can confirm for us.

that percentage sounds okay to me considering the improved level of service and peace of mind you will get from stanchart. I would say it all depends on how much time you have in your hands and what else you have going with the bank .. for some people it's a reasonable rate

No brainer, tbill is 9.5%pa before withholding tax then you give some 3% on the principal amount not even on interest yawa. Hata kama.

Yet you can apply, bid, get results & transfer the cash at the comfort of your office / laptop.

Why would i pay 3% of the principal amount , for what service?

I have a relative who is sooooooo lazy, they could not make that short trip to CBK to fill some forms, verify bank account and start bidding for free. Hata RTGS from our bank to CBK is free. Na kimpelempele mingi they went ahead and bought cbk bonds through Barclays. Can you say shaved super proper? I think out of a 12% bond they are getting 6% and are very happy about it. They keep talking about how much they are "making a good 12% without the hassle of having to walk allll the way to CBK." Bure sana.

Guys, don't waste so much energy typing such large paragraph's just to prove you are smarter than someone else. Things are not always black and white, there are good reasons to pay the 2% or 3% especially with a word-class reputable provider like stanchart. you just DON"T KNOW WHAT YOU DON"T KNOW

Tell us in black & white, we are all ears!!!
