[IRS](https://resellerindex.com/changes/irs/) Tax Effective Nov 9, 2026 · announced Sep 21, 2026 ### [Car loan interest deduction: final rules take effect Nov 9, 2026](https://resellerindex.com/changes/irs/2026-11-09-irs-car-loan-interest-final-regulations/) Final regulations on the new deduction for car loan interest (T.D. 10054, Internal Revenue Bulletin 2026-39, Sept. 21, 2026) take effect Nov. 9, 2026. The deduction is up to $10,000 of qualified interest per return, reduced by $200 for each $1,000 of modified AGI over $100,000 ($200,000 joint), for loans taken out after 2024 on a new vehicle with final assembly in the US, in tax years 2025 through 2028. It covers only a vehicle bought for personal use, meaning you expected more than half its use to be personal. In the regulation's own example, a sole proprietor expecting 60% business use does not qualify, though the business share of the interest stays deductible as a business expense. General information, not tax advice: check with a tax professional. Your net on a $10 / $25 / $50 sale: n/a / n/a / n/a A tax deduction rule, not a fee. It covers only personal-use vehicles; the business share of interest stays a business expense.

[Whatnot](https://resellerindex.com/changes/whatnot/) Postage Effective Nov 4, 2026 ### [Whatnot will bill sellers for USPS weight adjustments from Nov 4](https://resellerindex.com/changes/whatnot/2026-11-04-whatnot-carrier-weight-adjustments/) For US shipments sent on or after November 4, 2026, USPS charges for packages that weigh more than their Whatnot-generated label go to the seller's Whatnot ledger. Until now Whatnot absorbed them. For now Whatnot still covers dimension and hazmat adjustments, and it doesn't pass on UPS adjustments yet. Sellers whose first sale was on or after Sept 5, 2026 aren't part of this rollout, and neither are sellers who use their own labels. Your net on a $10 / $25 / $50 sale: n/a / n/a / n/a Not a set fee. You pay USPS's charge only when the packed box weighs more than the label says. To avoid it, weigh the packed box and fix the shipping profile before you buy the label. You have 45 days to appeal a charge, and USPS decides the appeal.

[Whatnot](https://resellerindex.com/changes/whatnot/) Fees Effective Nov 1, 2026 ### [Whatnot Premier Shops lose their 10% commission discount on Nov 1](https://resellerindex.com/changes/whatnot/2026-11-01-whatnot-premier-shop-discount-ends/) Until October 31, 2026, Whatnot cuts a Premier Shop's commission by a relative 10%, so 8% becomes 7.2%. Starting November 1 that discount goes away, and the rate depends only on the seller's four-week sales tier. Premier Shops keep the badge, the extra visibility in search and priority support. Qualifying still takes $50,000 in sales, 250 orders and 10 shows in 90 days. Your net on a $10 / $25 / $50 sale: -$0.08 / -$0.20 / -$0.40 Premier Shop sellers only. A Tier 1 fashion Premier Shop going from 6.3% back to 7% keeps $0.07, $0.17 and $0.35 less; at the standard 8% tier (7.2% with the discount) it's $0.08, $0.20 and $0.40. Payment processing (2.9% + $0.30) is unchanged.

[Poshmark](https://resellerindex.com/changes/poshmark/) Postage Effective Oct 26, 2026 · announced Oct 8, 2026 ### [Poshmark will charge you for heavy packages shipped without an upgraded label](https://resellerindex.com/changes/poshmark/2026-10-26-poshmark-overweight-label-deductions/) From October 26, 2026, if you ship a package over 5 lb on the standard label without upgrading it, Poshmark takes the upgrade cost from your earnings. Poshmark used to absorb this cost. The upgrade is $5.00 for 5.01-10 lb and $10.00 for 10.01-15 lb. A package over 15 lb on one label costs $15.00 at 15.01-25 lb, or the full USPS price over 25 lb. Your net on a $10 / $25 / $50 sale: n/a / n/a / n/a Only if you ship over 5 lb without upgrading: -$5.00 (5.01-10 lb), -$10.00 (10.01-15 lb), -$15.00 (15.01-25 lb on one label). Upgrading first costs the same and avoids a surprise deduction.

[Mercari](https://resellerindex.com/changes/mercari/) Postage Effective Oct 19, 2026 · announced Sep 17, 2026 ### [Mercari Media Mail labels get cheaper: 1 lb $4.99 to $4.47](https://resellerindex.com/changes/mercari/2026-10-19-mercari-media-mail-labels-down/) From October 19, 2026, Mercari's prepaid Media Mail labels cost $4.47 for 1 lb (was $4.99), $5.22 for 2 lb (was $5.99) and $5.97 for 3 lb (was $6.99). The new prices apply to new and existing listings, whether the buyer or the seller pays shipping. They match the USPS Media Mail prices in effect from July 13, 2025 to July 11, 2026, so they're still $0.08 to $0.11 above USPS's current prices ($4.39 for 1 lb). Your net on a $10 / $25 / $50 sale: +$0.52 / +$0.52 / +$0.52 If you pay for a 1 lb Mercari Media Mail label. 2 lb: +$0.77; 3 lb: +$1.02.
