TDS rates and thresholds set withholding obligations across payment types; Form 13 or Form 15G/15H can reduce or eliminate TDS. The document lists TDS rates and threshold limits across payment categories, noting special rates for non residents and foreign companies, applicable surcharge and education cess rules, and mid year threshold changes. It explains that Form 15G/15H can secure no deduction under specified sections if PAN requirements are met, and that a taxpayer may apply to the Assessing Officer in Form 13 under Section 197 for a certificate authorising no deduction or deduction at a lower rate. Absence of PAN attracts a 20% TDS rate.
