What's the difference between late interest and late surcharge?

**Late interest** and **late surcharge** are not the same. Late surcharge (Law 6183) applies to public receivables, while late interest (Law 2577) is used for receivables paid according to a court decision from the administrative court. For private law receivables, Law 3095 applies.

How is the check delay interest calculated?

**Check Delay Interest Calculation:** The interest is calculated by multiplying the number of days between the check return date and the payment date by the annual statutory interest rate, then dividing by 365. For commercial checks, the rate is the **TCMB advance rate** plus 30%, while for consumer checks, the **Consumer Law** applies.

**Will I be exempt from late fees if I set up a payment plan?**

Yes, you will be exempt from most late fees and penalties under tax payment laws (similar to Law 7440). Any remaining balance will be recalculated with interest and must be paid.

Frequently asked questions

The late payment penalty is calculated as follows: Tax Amount × Annual Rate × (Number of Days / 365). For example, if you owe 10,000 TL in taxes and you're late by 90 days, the penalty would be: 10,000 × 72% × (90/365) = 1,775 TL in late payment penalty.
