Tax calculation Ticket and Account are different

I set up Product $8.95 and Tax 5%. 

On screen:
Ticket Total: $8.95
Tax: $0.45
Balance: $9.40

On Printed Bill:
the same as on screen

On Tickets screen:
Total: $9.39

In Database:
dbo.Tickets $9.39
dbo.AccountTransactions $9.40 and tax $0.45
dbo.Payments $9.40 

I tried set Tax template round 0 and 2 but results are the same. Is there another setting? I try to avoid tax included price becuase if the tax rate change I don't have to change all the price again.
