ReplyEvery year, HMRC answers millions of calls. A call is recorded as ‘answered’ when a customer got through to an adviser after hearing the automated messages and choosing the option to speak to an adviser (this is also referred to as ‘adviser attempts handled’ (AAH) in HMRC published data). A call is recorded as ‘abandoned’ when a customer hears the automated messages and chooses the option to speak to an adviser, but then hangs up before their call is answered. Customers may hang up before their call is answered for a number of reasons. For example, they may have had their query answered by HMRC’s recorded messages, they may have found the information they require online or they may have decided to call back another time. The below tables provide a breakdown of calls answered and calls abandoned over the past ten years for HMRC’s main helplines: Calls answered2015-162016-172017-182018-192019-202020-212021-222022-232023-242024-252025-26 YTDChild Benefit1,815,1662,071,5902,009,1351,777,7361,712,3001,386,8181,569,2671,377,8171,017,1401,142,678833,880National Insurance1,483,0951,671,6771,475,4161,377,8551,349,9291,069,7101,247,3491,242,9431,097,0361,044,772682,058Tax Credits Helpline and Tax Credits Payment Helpline – combined figures11,509,09011,581,9139,265,2066,671,7784,557,1612,343,0441,895,3841,587,6331,147,483647,815109,086Corporation Tax373,190500,940508,270475,961441,835378,406507,372506,145421,603378,862231,741Stamp duty land tax112,333154,415164,259144,667131,610100,624122,429122,582107,538103,22971,526Agent Dedicated Line1,707,2241,851,7531,432,4051,360,2341,374,380705,308968,9251,041,355640,405503,105289,091Construction Industry Scheme Helpline584,630496,413376,861343,789334,675225,708293,478281,009239,920168,99094,016Employers Helpline819,618984,212976,437939,286755,040588,062650,432686,890589,002506,637328,452Online Services Helpline675,1581,073,270982,535730,981635,733548,319688,575780,038978,228932,393611,680PAYE6,513,0628,913,0088,199,6217,707,5647,127,5564,703,8785,973,9095,908,2094,405,3654,586,3523,177,096Self Assessment Helpline2,389,4003,094,0583,444,4523,219,5523,236,7192,560,8622,602,9172,643,6911,441,3801,904,3631,113,666VAT-282,301644,072585,882771,572500,095623,494657,205486,335395,747277,184 Calls abandoned2015-162016-172017-182018-192019-202020-212021-222022-232023-242024-252025-26 YTDChild Benefit653,242190,353147,771171,017224,611194,436267,186410,792332,543256,223146,160National Insurance891,375126,759118,987156,762132,920109,035196,346415,222336,696277,05884,032Tax Credits Helpline and Tax Credits Payment Helpline – combined figures2,295,327596,654726,769599,007539,088360,618565,334420,411334,029208,92310,735Corporation Tax99,49837,06451,40645,76363,95735,26778,89489,90068,08456,57435,108Stamp duty land tax16,5189,96912,63413,92416,3216,20810,55617,64810,1088,3845,989Agent Dedicated Line13,82124,21911,4135,1277,855175,775110,683119,404115,31685,35628,577Construction Industry Scheme Helpline72,50031,31037,28939,09533,56629,73236,74349,25037,57419,08710,167Employers Helpline226,89050,28863,01966,16362,85263,13586,365138,787122,053125,47081,521Online Services Helpline350,563138,02797,650108,720119,130126,824128,903235,456197,111226,44676,031PAYE2,755,469401,321840,726917,2321,067,3041,427,8421,303,2841,769,3381,765,2271,248,174628,559Self Assessment Helpline1,193,023206,772372,471380,719443,148611,544689,0071,144,135704,546523,645201,569VAT-13,14343,17384,53972,64862,494127,450162,969150,24472,01436,010 Further telephony data is published as part of HMRC’s quarterly performance reports: www.gov.uk/government/collections/hmrc-quarterly-performance-updates And HMRC publishes a historical data series as part of its annual report and accounts: www.gov.uk/government/publications/hmrc-annual-report-and-accounts-2024-to-2025Data covering VOA helplines:Financial YearAnsweredAbandoned2015-16283711491732016-17327896673482017-18232687563342018-19225205728982019-20261216974602020-21106016275542021-22222467389492022-23218353378962023-24202043521912024-25201663712252025-2026 (YTD)12931919618
